In 2006, the seventh round of <strong>Interlaboratory</strong> 

<strong>Comparison</strong> on Dioxins in Food was conducted on the 

determination of the 2,3,7,8-chlorinated dibenzo-pdioxins 

(PCDDs) and dibenzofurans (PCDFs) as well as 

dioxin-like non-ortho and mono-ortho chlorinated 

biphenyls (PCBs) in three different food items. In this 

round, also polybrominated diphenyl ethers (PBDEs) 

as well as the six indicator PCBs could be determined 

and reported. The objectives of this interlaboratory 

comparison study were a) to offer a quality assurance 

instrument for the participating laboratories, b) to 

assess the between laboratory reproducibility and c) to 

assess the readiness of expert laboratories world-wide 

to determine levels of chlorinated and brominated 

persistent organic pollutants in regular foodstuffs. 

The 2006 study was performed on sample homogenates 

of egg yolk, halibut filet and breast milk. 

In addition, five standard solutions were provided 

containing known concentrations of a) PCDDs/ PCDFs, 

b) non-ortho PCBs, c) mono-ortho PCBs, d) PBDEs and 

e) indicator PCBs. The testing materials were sent to 

104 laboratories in February 2006, and results were 

returned from 96 laboratories in 28 different countries 

by the deadline in May. Most laboratories analysed all 

the three food items. A draft report was made available 

on the web in July and was discussed among the 

participants at a consultation meeting during the 

DIOXIN2006 Symposium in Oslo, Norway. 

This report presents the reported results for: all 

seventeen 2,3,7,8-substituted PCDDs/PCDFs, the nonortho 

substituted PCBs #77, 81, 126 and 169 and the 

eight mono-ortho substituted PCBs #105, 114, 118, 

123, 156, 157, 167, 189 in the three food items on a 

fresh weight basis. In addition, the results for eight 

PBDE congeners BDE #28, 47, 99, 100, 153, 154, 183 

and 209 and six indicator PCBs #28, 52, 101, 138, 153 

and 180 were reported from those laboratories that 

voluntarily determined their concentrations. Nondetected 

congeners were assigned a concentration 

corresponding to the reported detection limit except 

for PBDEs and indicator PCBs where non-detects were 

removed from the data set. The consensus concentration 

(assigned value) for each analyte in the three food 

samples was determined as follows: The median of all 

reported concentrations for each analyte was calculated. 

All values above two times the median were 

removed from the calculation. The consensus median 

and consensus mean plus standard deviation (SD) were 

calculated from the remaining data. Toxic equivalents 

(TEQs) were calculated from the consensus values of 

individual congeners using the toxic equivalency factors 

derived by WHO in 1998. Z-scores for PCDD/PCDF 

TEQs were calculated for each laboratory using ±20% 

of the consensus TEQs as a value for target standard 

deviation (σ). Further, Z-scores were calculated for 

the non-ortho PCB TEQ, the mono-ortho PCB TEQ, the 

total TEQ, the sum of six indicator PCBs, the sum of 

seven PBDEs and for each single congener in all three 

matrices. 

The consensus values for the standard solutions 

were calculated in the same manner except that 

values outside ± 50% of the median of all values were 

removed prior to the final calculation of the consensus 

median and mean. The consensus values for the lipid 

content were calculated by first excluding results deviating 

more than two SD from the mean of all values 

and then re-calculating the median, mean and SD. 

For the determination of total TEQs, Z-scores 

within ±1 were obtained by 61-79% of the laboratories. 

The majority of the laboratories (81-92%) 

reported results for total TEQ with a trueness of ±40% 

for all food samples (Z-score ±2). Also the relative 

standard deviation (RSD) calculated for the total TEQ 

after removal of outliers is quite low (8-15%). It is 

therefore concluded that the performance of laboratories 

world-wide in determining dioxin-like compounds 

is generally good for the food samples included in this 

study. 

Forty-one laboratories reported concentrations 

for the seven tetra- to hepta-BDEs and 63 laboratories 

reported results of the six indicator PCBs. The 

sum of the PBDE concentrations ranged from 79 pg/g 

fresh weight in breast milk to 1.4 ng/g fresh weight 

in halibut filet. The RSD for PBDE concentrations on 

fresh weight basis was on average 27, 36 and 38% 

for breast milk, egg yolk and halibut filet, respectivly. 

The consensus concentrations calculated for BDE-209 

are just indicative values as few laboratories reported 

this congener. The sum of concentrations for indicator 

PCBs were 2.1, 9.9 and 19 ng/g fresh weight for breast 

milk, halibut filet and egg yolk, respectively. The corresponding 

average RSDs were 28, 31 and 32%. 

��

�� 

In order to ensure consumer protection and reduce human 

exposure to dioxins and dioxin-like PCBs through 

food consumption, many countries request frequent 

monitoring of the presence of these toxic pollutants 

in food and feed. There is therefore a large demand 

for chemical laboratories that are able to determine 

these contaminants at low levels in food and feed. It 

is usually required by the authorities that laboratories 

performing such measurements are accredited according 

to ISO standards and prove their competence by 

successful participation in interlaboratory studies. 

This study is the seventh round of a world-wide 

interlaboratory comparison study on dioxin-like compounds 

in food organised by the Department of Analytical 

Chemistry, Division of Environmental Medicine, 

Norwegian Institute of Public Health in Oslo, Norway. 

The exercise took place from February 2006, 

when the samples were shipped to the laboratories 

for analysis, to the beginning of May 2006, when the 

last reports on the results were received. A draft report 

was made available to the participants on the web 

(http://www.fhi.no) in July and was discussed during a 

consultation meeting at the DIOXIN2006 Symposium 

in Oslo, Norway. 

The main objective of this exercise was to assess 

the between laboratory reproducibility of dioxin-like 

compounds analyses in frequently consumed foods 

and provide a QA/QC instrument for each participating 

laboratory to contribute to its proficiency. Participants 

were also asked to voluntarily determine the concentrations 

of eight PBDEs and six indicator PCBs in the 

food samples in order to assess the readiness of laboratories 

to analyse these persistent organic pollutants. 

All of the participants from previous rounds of this 

series of “<strong>Interlaboratory</strong> <strong>Comparison</strong>s on Dioxins in 

Food” were invited to participate. In addition, several 

other laboratories announced their participation. 

There was no limit to the total number of participating 

laboratories. The 96 laboratories that submitted 

results, and thereby contributed to the study results, 

are presented in Table 1.

As in the previous rounds of this interlaboratory comparison 

studies, the test material chosen represented 

naturally contaminated food samples. The analytes to 

be determined by each participating laboratory were 

all seventeen 2,3,7,8-substituted PCDDs/PCDFs, the 

four non-ortho substituted PCBs #77, 81, 126 and 169 

and the eight mono-ortho substituted PCBs #105, 114, 

118, 123, 156, 157, 167 and 189. In addition, laboratories 

were asked to determine on a voluntary basis 

eight PBDEs #28, 47, 99, 100, 153, 154, 183 and 209 

and six indicator PCB congeners PCB #28, 52, 101, 138, 

153 and 180. These six PCB congeners belong together 

with the mono-ortho PCB #118 to the selection of 

PCBs commonly referred to as ICES-7. 

The analysis should be performed using the laboratories 

own methods for sample preparation and instrumental 

analysis, their own standards and quantification 

procedures, and their own method for lipid determination. 

It was recommended that laboratories determine 

as many as possible of all 2,3,7,8-substituted PCDDs/ 

PCDFs and dioxin-like PCBs, PBDEs and indicator PCBs. 

The report was to include the determined lipid percent 

for the test samples. Also the actual sample and lipid 

intake (g) for each determination should be reported. 

For each sample, laboratories were to report the found 

concentration on fresh weight basis for each congener 

which was detected (e.g. S/N ≥3) as well as the level 

of determination (LOD, e.g., S/N =3). Non-detected 

congeners (e.g. S/N

detection limit as concentration for non-detected 

congeners (upperbound concentration). For PBDEs and 

indicator PCBs, non-detected congeners were removed 

from the data set prior to consensus calculation. Outliers 

were defined as those values above two times the 

median of all values and were removed from the data 

set. The consensus values were defined as the median 

of the remaining data for each congener. In addition, 

the consensus mean and SD were calculated from this 

data set for each congener. Those congener data which 

had been removed prior to consensus calculation are 

marked in the tables presenting the individual results. 

For the standard solutions, outliers were defined 

as those values outside ± 50% of the median of all 

reported values. Consensus median, mean and SD were 

calculated from the remaining data. The consensus 

of the lipid content was calculated as the mean after 

removal of values outside ± 2SD. 

TEQs were calculated from the consensus values 

for PCDDs/PCDFs, non-ortho PCBs, and mono-ortho 

PCBs, using the toxic equivalency factors derived by 

WHO in 1998. As the detection limit was used for the 

concentration of non-detects, these TEQs represent 

upper bound concentrations. 

Z-scores for PCDD/PCDF TEQ as well as for the 

non-ortho PCB TEQ, the mono-ortho PCB TEQ, the 

total TEQ, the sum of six indicator PCBs, the sum of 

seven PBDEs and for each singel congener were calculated 

for each laboratory according to the following 

equation: 

z = (x – X)/� 

where x = reported value; X = assigned value (consensus); 

� = target value for standard deviation. A � of 

20% of the consensus was used, i.e. z-scores between 

+1 and -1 reflect a deviation of ± 20% from the consensus 

value. 

�� 

The draft of the final report was prepared by the coordinators 

and published on the web in July 2006. The 

draft was discussed at the consultation meeting at the 

DIOXIN2006 Symposium in August in Oslo, Norway. 

A certificate, stating the participant’s code, will 

be sent to each participant contributing to the results 

together with the printed report in autumn 2006. 

Further copies of the report may then be ordered from 

the co-ordinators for a fee covering printing and mailing 

costs. 

�� 

The study was initiated and carried out by the 

Department of Analytical Chemistry, Division of 

Environmental Medicine, Norwegian Institute of Public 

Health, Oslo, Norway. Members of the co-ordination 

committee were: 

Line Småstuen Haug, Senior Engineer

��

�� 

Results are presented in the chapters below. A participating 

laboratory will be able to compare its performance 

congener by congener with the other laboratories. 

Since variations in performances are based on 

several factors, it is recommended that each laboratory 

carefully evaluates the factors that, favourably or 

unfavourably, have contributed to its performance. A 

general reader of the report, who has no access to the 

laboratory codes, will be able to get a picture of the 

analytical performance of laboratories world-wide for 

determining dioxins, dioxin-like PCBs, indicator PCBs 

and PBDEs in regular foods. 

�� 

Ninty-six laboratories from 28 different countries 

have submitted results. In appendix C the consensus 

statistics are given on fresh and lipid weight basis for 

concentrations and TEQ values of individual congeners, 

a summary of TEQ values for each food item, and the 

Z-score plots based on a target deviation of ±20%. 

Further, the results of the lipid determinations are 

presented. Finally, individual results reported by the 

laboratories for each congener are given for egg yolk, 

halibut filet and breast milk in appendix 2, 3 and 4.. 

�� 

�� 

�� 

Concentrations for PCDDs/PCDFs were reported by 88 

laboratories. The average RSD for the 17 congeners 

was 8.5% ranging from 7.4% for 2,3,7,8 TCDD to 11% 

for 1,2,3,4,6,7,8,9-OCDF. The calculation of Z-scores 

for the TEQs (target 13.6 pg TEQ/μl) of the PCDD/PCDF 

standard solution showed that 98% of the labs were 

within the range of ±20% of the consensus value. This 

demonstrates that high quality calibration solutions 

were used. 

�� 

For the egg yolk sample, PCDD/PCDF results from 82 

laboratories were received. The consensus TEQ was 0.21 

pg/g fresh weight and 0.94 pg/g lipid weight. Z-scores 

within ±1 were obtained by 66% of the laboratories 

and 83% of the laboratories had Z-scores within ±2. 

�� 

PCDD/PCDF concentrations in the fish sample were reported 

by 87 laboratories. The consensus TEQ was 0.33 

pg/g fresh weight. Z-scores were within ±1 for 64% of 

the laboratories and within ±2 for 84% of the laboratories. 

More than 90% of the PCDD/PCDF TEQ is made 

up by the four congeners 2,3,7,8-TCDD, 1,2,3,7,8- 

PeCDD, 2,3,7,8-TCDF and 2,3,4,7,8-PeCDF. 

�� 

For breast milk 82 laboratories have determined 

PCDD/PCDF concentrations. The consensus TEQ was 

0.19 pg/g fresh weight and 5.9 pg/g lipid weight. The 

average RSD was 33% ranging from 19-65%. Z-scores 

for PCDD/PCDF TEQ within ±1 were obtained by 73% 

of the laboratories and 88% had Z-scores within ±2. 

�� 

�� 

The 12 dioxin-like PCBs in the analyte solution were 

analysed and reported by 85 to 87 laboratories. The 

RSDs for the different congeners were 8.5-11% with 

an average of 10%. 

�� 

Dioxin-like PCB concentrations were reported from 73 

to 78 laboratories. The concentrations of the 12 congeners 

varied between 0.49 pg/g fresh weight (CB-81) 

and 1210 pg/g fresh weight (CB-118). The dioxin-like 

PCBs contribute as much as 97% to the total TEQ in 

the sample with CB-126 as the dominanting contributor. 

This special pattern of dioxin-like compounds 

results from the the use of free-range eggs from a 

contaminated area. The average RSD for concentrations 

of individual dioxin-like PCB congeners on fresh 

weight basis was 23% ranging from 13% for CB-126 

to 39% for CB-123. 

�� 

Between 77 and 82 laboratories have measured and 

reported dioxin-like PCB concentrations in halibut. The 

concentrations ranged from 0.34 pg/g fresh weight to 

1.8 ng/g fresh weight. The dioxin-like PCBs contribute 

to about 80% of the total TEQ in the sample. 

�� 

Dioxin-like PCBs were reported by 75 to 80 laboratories. 

Levels were ranging from 0.033 pg/g fresh weight 

��

to 227 pg/g fresh weight. The average RSD was 25%. 

The contribution of the dioxin-like PCBs to the total 

TEQ was about 50%. 

�� 

In Figure 1, the contribution of the three groups of 

dioxin-like compounds is depicted. For all three sample 

types, dioxin-like PCBs contributed to 50% or more of 

the total TEQs, demonstrating the importance of PCBs 

for the determination of the total 2,3,7,8-TCDD related 

toxic potency of food samples.

Figure 1. Contribution of PCDDs/PCDFs, non-ortho 

PCBs and mono-ortho PCBs to the total TEQ in the food 

samples used in this interlaboratory comparison study. 

The RSD for total TEQ on fresh weight basis calculated 

from the RSD of individual congeners was 11.9% for egg 

yolk, 15.2% for halibut filet and 8.3% for breast milk. 

�� 

�� 

�� 

�� 

Indicator PCBs were reported by 63 laboratories in the 

analyte solution. The average RSD was 11% ranging 

form 10-12%. 

�� 

For the egg yolk sample indicator PCB results were 

received from 56 laboratories. The concentrations 

were varying between 15 pg/g fresh weight and 6.9 

ng/g fresh weight. The RSDs were ranging from 24- 

36%. The consensus median for the sum of indicator 

PCBs,18.6 ng/g fresh weight, was quite high due to the 

partial use of contaminated free-range eggs. 

�� 

Within the deadline 61 laboratories reported results 

of indicator PCBs in halibut filet. The concentrations 

ranged form 0.21 ng/g fresh weight to 3.9 ng/g 

fresh weight with a consensus median for the sum of 

indicator PCBs of 10 ng/g fresh weight. The average SD 

was 31% ranging from 27-35%. 

�� 

Reports were obtained from 58 laboratories. The concentrations 

of indicator PCBs in the breast milk were 

ranging from 9.3 pg/g fresh weight to 0.96 ng/g fresh 

weight and the consensus median for the sum was 2.1 

ng/g fresh weight. The average RSD was 28% ranging 

from 22-38% for CB-180 and CB-28, respectively. 

�� 

�� 

The PBDE standard solution was analysed by 40 to 41 

laboratories for BDE-28 to BDE-183, but only 29 laboratories 

reported values for BDE-209. The RSDs were 

between 11-13%. 

�� 

PBDE concentrations were reported by 33 to 35 

laboratories, except for BDE-209 for which only 25 

results were received. The consensus concentrations 

were quite low, varying between 1.4 pg/g fresh weight 

for BDE-28 and 198 pg/g fresh weight for BDE-99. The 

concentration for BDE-209 at 130 pg/g fresh weight 

must be regarded as indicative. The sum of tri- to 

heptaBDEs was 456 pg/g fresh weight. The range of 

RSDs on fresh weight was 21-73% with an average of 

36%, excluding BDE-209. 

�� 

Within the deadline 38-39 laboratories had reported 

results for tri- to hepta BDEs. The concentrations varied 

between 0.89 pg/g fresh weight and 1.1 ng/g fresh 

weight. The sum of tri- to heptaBDEs was 1.4 ng/g 

fresh weight. The RSD calculated from the concentrations 

on fresh weight ranged from 28-69% with an 

average of 38% for the tri- to heptaBDEs. 

�� 

Between 34 and 35 laboratories reported results for 

tri- to hepta BDEs and 24 reported results for BDE- 

209. The sum of tri to hepta-BDEs was 79 pg/g fresh 

weight. The RSDs for the individual congeners were 

ranging from 18 to 41% with an average of 27%, 

excluding BDE-209. 

�� 

The mean and RSDs (in parentheses) for the lipid 

contents of the food samples were calculated to 

22.8% (8.0%) for egg yolk, 2.58% (25%) for herring 

and 3.19% (13%) for breast milk. The distribution of 

Z-scores shows that several laboratories have reported 

a far too low lipid content for the halibut filet which 

indicates that they have not been able to efficiently 

extract the lipids from the lean fish tissue. 

��

�� 

The laboratories were asked to provide information regarding 

the methods used for lipid determination. The 

questions were focused on solvents used and extraction 

techniques. Figure 2 summarise the frequency of 

different extraction techniques used. 

The frequency of different extraction methods 

used for egg yolk and halibut filet is similar, except 

that twice as many used liquid/liquid extraction for 

egg yolk than for halibut filet. For breast milk as many 

as 65% of the labs used liquid/liquid extraction and 

20% used Soxhlet extraction. 

It is generally assumed that it is advantageous to 

use a mixture of polar and apolar solvents to obtain 

efficient extraction of both polar and apolar lipids. In

this study 72, 72 and 84% of the laboratories reported 

that they used both polar and apolar solvents for the 

egg yolk, halibut filet and breast milk, respectively. 

When comparing the reported lipid content with the 

polarity of solvents used, no relationship was found. 

Laboratories reporting results based on use of either 

only polar or apolar solvents, obtained as good 

Z-scores for all three matrices as laboratories using 

solvents of different polarity. This implies that either 

the choice of solvent is of minor importance for the 

quantitative extraction of lipids for these matrices, or 

that the particular extraction technique has an equally 

important influence on the extraction efficiency.

The laboratories are acknowledged for their participation 

in this interlaboratory comparison and their interest 

in its overall objectives, thereby making it clear 

that they value good analytical performance. All the 

individual analysts are acknowledged for their contributions 

to the results. 

We are grateful to Cambridge Isotope Laboratories, 

Inc. for providing the standard solutions for this interlaboratory 

study. We thank Dr. Rainer Malisch, CVUA, Freiburg, 

Germany for providing us the contaminated free-range 

eggs and the National Institute of Nutrition and Seafood 

Research, Bergen, Norway for the halibut sample.

Announcement for 

<strong>Interlaboratory</strong> <strong>Comparison</strong> on Dioxins in Food 2006 

Introduction 

We herby announce the seventh round of interlaboratory comparison on the determination of 

dioxins, PCBs and PBDEs in food. It is open for academic, regulatory as well as commercial 

laboratories world-wide. The organiser of this study is the Department of Analytical 

Chemistry at the Norwegian Institute of Public Health in Oslo, Norway. The study is 

scheduled to take place from February to May 2006. A draft report will be available prior to 

the evaluation meeting to be held at the Dioxin 2006 Symposium in August in Oslo, Norway. 

The final report will be prepared and sent to participants by November 2006 together with a 

certificate for participation. 

Objectives 

The objectives of this exercise are to assess the interlaboratory consistency in results from 

analyses of dioxins, PCBs and PBDEs in regular foods known to contribute to the intake in 

the general population and to assess the world-wide readiness and capacity in analysing 

dioxins and other halogenated persistent pollutants in food. The study also serves as a quality 

assurance instrument for the participating laboratories. 

Participants 

We encourage all laboratories world-wide working in this field to participate and assess their 

analytical performance. Participants are requested to completely fill out the Registration Form 

and mark for the desired sample types and whether they intend to determine PBDEs. 

Analytical requirements 

In this interlaboratory comparison, all the seventeen 2,3,7,8-substituted PCDDs and PCDFs, 

the four non-ortho PCBs, CB-77, 81, 126 and 169 as well as the eight mono-ortho PCBs, CB- 

105, 114, 118, 123, 156, 157, 167, and 189 will be assessed. In addition, you are invited to 

determine on a voluntary basis six marker PCBs and eight polybrominated diphenylethers 

(PBDEs). The concentration of the following congeners should be reported: CB-28, 52, 101, 

138, 153 and 180 and BDE-28, 47, 99, 100, 153, 154, 183 and 209. The test materials consist 

of three fresh food homogenates; Egg yolk, Halibut filet and Breast milk. You can choose to 

analyse one, two or all three of the food items. We encourage you to determine as many 

analytes as possible. You are further requested to determine and report the lipid content of the 

foods. 

We also include standard solutions of all analytes that should be analysed as solutions of 

known concentration, which may be used to check your own calibration solutions. 

Test material 

The test materials consist of three unfortified natural food product homogenates, Egg yolk (E) 

~60 g, Halibut filet (H) ~100 g, and Breast milk (B) ~130 g. They will be distributed by DHL 

to the participating laboratories labelled as test material E, H, and B.

Please note: 

In order to avoid delay at customs, please inform us if there are import restrictions for 

any of these samples in your country. 

Instructions for analysis and reporting 

Further detailed instructions and reporting forms will be sent out simultaneously with the

1. Introduction 


Instructions for participants 

February 2006 

This is the seventh round of the interlaboratory comparison exercise on the determination of 

dioxins, PCBs and PBDEs in food organised by the Department of Analytical Chemistry, 

Norwegian Institute of Public Health, Oslo, Norway. The objective of this exercise is to assess 

the interlaboratory comparability of the results from analyses of all dioxins and dioxin-like 

PCBs included in the WHO98-TEF scheme in regular foods. Participants may also determine 

and report concentrations of six marker PCBs and eight polybrominated diphenylethers 

(PBDEs). The exercise serves as a quality assurance instrument for the participating 

laboratories. A further objective is to assess the world-wide readiness and capacity for the 

determination of dioxin-like compounds, marker PCBs and PBDEs in food. Instructions for 

the analysis and submission of results are given below. 

Please read these instructions carefully before starting the experimental work. 

The participating laboratories will collaboratively assess the interlaboratory comparability in 

the analytical performance for determination of: 

� dioxins and furans: all seventeen 2,3,7,8-substituted PCDDs and PCDFs 

� non-ortho PCBs: CB-77, 81, 126 and 169 

� mono-ortho PCBs: CB-105, 114, 118, 123, 156, 157, 167 and 189. 

� marker PCBs: CB-28, 52, 101, 138, 153 and 180 

� PBDEs: BDE-28, 47, 99, 100, 153, 154, 183 and 209 

in egg yolk (E), halibut filet (H), and breast milk (B).The mentioned analytes should also be 

determined in the respective five standard solutions. 

2. Participants 

A list of participants is attached. 100 laboratories have announced their participation in the 

study. 

3. Design of the study 

3.1 Test materials 

Samples 

One standard solution of each: 

� EDF-5008-50 with PCDDs/PCDFs at concentrations 2:5:10 pg/�l for tetra:penta-hexahepta:octa 

chlorinated dibenzo-p-dioxins/-dibenzo furans respectively 

� EC-4986/1000 with non-ortho PCBs at concentration 10 pg/�l 


32 

1

� EC-4987/100 with mono-ortho PCBs at concentration 100 pg/�l 

� EC-5179/50 with marker PCBs at concentration 100 pg/�l 

� EO-5103/100 with PBDEs at concentration 25 pg/�l, except BDE-209 at 100 pg/�l. 

One sample of each 

� ca. 60 g egg yolk, lipid content about 20-27 % 

� ca. 100 g halibut filet homogenate, lipid content about 1-5% 

� ca. 150 g breast milk, lipid content about 2-5% 

Fortification 

The samples are prepared from regular market foods. There is no fortification or spiking of 

the PCDD, PCDF, PCB or PBDE analytes in the food samples. 

Shipment 

The samples are fresh frozen food homogenates. They are distributed by DHL and should 

reach the receiving laboratory in good condition within a few days. The airwaybill numbers 

will be made available for the participants to trace the shipment at http://www.dhl.com. 

3.2 Coding 

Coding of laboratories 

Upon arrival of the samples in the participant’s laboratory, the Microsoft excel file named 

"Participant confirmation", shall be filled in and immediately returned to the co-ordinators by 

e-mail or telefax. The code of the laboratory will then be given by the co-ordinators. The 

laboratory codes will not be revealed to the other participants or to third parties. 

Coding of samples 

Egg yolk samples E 

Halibut filet samples H 

Breast milk samples B 

The above sample coding is marked on the sample bottles. 

3.3 Analytical procedure 

Methods to be used 

Laboratories shall use 

� their own methods for sample preparation and instrumental analysis 

� their own internal- and quantification standards 

� their own lipid determination procedure 

Standard solutions 

The standard solutions should be analysed using the laboratory’s own quantification standards 

and methods and the results shall be reported. 

General 

Beware of the high risk of background contamination and positive blank values when 

analysing food samples with levels of dioxins, PCBs and PBDEs in the low ppt range. 


33 

2

Use sample size according to expected levels of dioxins for the determinations in order to 

achieve a detection level that leaves as few as possible analytes as non-detected. The sample 

amount dispatched is not meant for replicate analyses. 

The samples might become inhomogeneous during freezing and transport. Re-homogenise all 

received material of each food item before any portion is taken out for analysis. 

4. Reporting 

4.1 Results to be reported 

Laboratories are recommended to report as many as possible of the congeners mentioned in 

chapter 1. 

The reports must include the determined lipid percent for all three matrixes. Also, the actual 

sample intake (g) for each determination must be reported. 

The analytical report must include concentrations for all the congeners in all the samples on 

fresh weight basis, see Report forms B, C, D for PCDD/PCDF and dioxin-like PCBs and 

Report form 2, 3, 4 for marker PCBs and PBDEs . 

Laboratories must report one concentration on fresh weight basis for each congener which is 

detected (S/N �3), as well as the limit of determination (LOD, S/N =3) for each sample. Nondetected 

congeners (S/N

The electronic report shall be sent to dioxin@fhi.no within the deadline. 

If necessary, a hard copy of the Report forms can be provided. Please contact one of the coordinators. 

If a hard copy report is used, it shall either be faxed to: + 47 22 04 26 86 or mailed 

to:

P.O. Box 4403 Nydalen 

N-0403 Oslo, Norway 

Deadline 

The reports must be in our hands no later than May 5, 2006 to enable us to prepare the 

draft report for the Dioxin 2006 Symposium in Oslo, Norway. There will be no extension of 

this deadline. A confirmation for receiving your results will be sent to you by e-mail within a 

week. 

5. Statistical evaluations 

Prior to the final report, a draft version will be prepared based on the data reported by May 6. 

The co-ordinators will calculate mean, median and between-laboratory standard deviations for 

each congener. Outliers will be removed, and consensus values will be calculated. In case of 

extreme deviation from normal distribution, appropriate procedures will be used to get a best 

available estimate of the true value. For the dioxin-like compounds, TEQ values will be 

calculated for each laboratory and a consensus TEQ value based on the consensus of the 

congeners. Z-scores will be calculated for laboratories’ results for PCDD/PCDF TEQs and 

PCB TEQs. 

Statistical results based on the reported data as well as other important information from the 

evaluation of the data, will be discussed during a consultation meeting in August at the Dioxin 

2006 Symposium in Oslo, Norway. 

6. Final report 

The final report will be prepared by the co-ordinators. All participants will be presented by 

their laboratory code. A draft will be published on the internet in July/August. The results will 

be discussed during the Dioxin 2006 Symposium in Oslo, Norway. The final report will be 

printed by November 2006 and thereafter distributed to the participating laboratories. The 

report will also be partly available in an electronic version on http://www.fhi.no. Certificates 

of participation in the study will be given to all laboratories submitting results. 

7. Fee 

To all laboratories that have received the materials, an invoice will be sent. The participation 

fee for any combination of the 29 dioxin-like congeners, six marker PCBs and 8 PBDEs is 

� EURO 1000 for one food item 

� EURO 1200 for two food items 

� EURO 1400 for the complete set of all three food items. 


35

Four standard solutions will be distributed free of charge to all participants. A fifth standard 

solution containing PBDEs will be distributed to those laboratories which intend to determine 

PBDEs. 

Invoices will be sent out after we have received the Participant confirmation from the 

participants.

Presentation of results for lipid determination 

Removal of outliers and calculation of consensus were done by the following procedure: 

1. The mean was calculated from all the reported data. 

2. Values outside a range of � 2 � the standard deviation of this mean, were defined as 

outliers and removed from the data set. 

3. Mean, standard deviation and median were re-calculated from the remaining data. This 

mean was called consensus. 

The diagram shows the reported data with consensus and consensus � the new standard 

deviation � 2.

Z-Scores of lipid content 

Lab code 

Consensus 

mean 

Z-scores of lipid content were calculated for each laboratory according to the following 


z = (x – X)/� 

where x = reported value; X = assigned value (consensus); � = target value for standard 

deviation. A � of 20% of the consensus was used, i.e. z-scores between +1 and -1 reflect a

Appendix 1: Presentation of results: Analyte solution 

Statistic calculations for PCDDs, PCDFs, dioxin-like PCBs, indicator PCBs and PBDEs 

The analyte solution contained 

� PCDDs/PCDFs at concentrations 2:5:10 pg/�l for tetra:penta-hexa-hepta:octa chlorinated 

dibenzodioxins/furans respectively. 

� non-ortho PCBs at concentration 10 pg/�l. 

� mono-ortho PCBs and indicator PCBs at concentration 100 pg/�l. 

� PBDE at concentration 25 pg/�l, except BDE-209 at 100 pg/�l. 

These concentrations are called the congeners' target value. 

For each congener, the outliers were removed and the consensus calculated according to the 

following procedure: 

1. The median was calculated from all the reported data. 

2. Values outside a range of 50 % to 150 % of this median, were defined as outliers and 

removed from the data set. 

3. Median, mean and standard deviation were re-calculated from the remaining data. This 

median and mean were called consensus median and mean. 

The diagram shows the target value and the reported data. Values outside a range of 50 % to 

150 % of “median of all values”, were defined as outliers and are not shown in the plot.

Appendix 2: Presentation of results: Egg yolk 

Statistic calculations for PCDDs, PCDFs and dioxin-like PCBs 



1. The median was calculated from all the reported data, using the detection limit as 

concentration for non-detected congeners. 

2. Values exceeding 2 � this median, were defined as outliers and removed from the data set. 


second median was called consensus. 

Statistic calculations for indicator PCBs and PBDEs 




concentration for non-detected congeners (NDs). 


The NDs were also removed. 



4. For comparison, median, mean and standard deviation were also calculated without 

removing NDs. 

The diagram shows the reported data up to approximately the limit for outliers (2 � the first 

median).
