www.esdat.net Esdat Environmental Database Management Software +61 2 8875 7948 GAC have been derived for 4 generic land-uses; residential with consumption of homegrown produce, residential without consumption of homegrown produce, allotments and commercial land-use. The generic assumptions used for deriving the GAC for each of these land-uses are described in detail in the Environment Agency of England and Wales SR3 report (2009a). Each land-use scenario has had GAC produced for 3 soil organic matter (SOM) contents; 1%, 2.5% and 6%. This range in SOM is considered a reasonable representation of the majority of soils within the UK. Note that due to limitations in time and scope of the project plant uptake factors were not derived for the metals (see Section 3.4) and therefore the metals GAC have only been produced for the residential without consumption of homegrown produce and commercial land-uses. Physico-chemical data were collated for a further 9 organic contaminants as listed in Table 2.2. However, there were insufficient toxicological data available to derive health criteria values (HCV) that were acceptable to the entire group of risk assessors and consequently GAC are not presented for these contaminants. This is not to say that there are insufficient data to assess the risk from these compounds on a site specific basis but rather that the uncertainties involved prevent the derivation of industry agreed GAC for general use on all sites within the UK. Data collated for the 44 contaminants assessed are provided in Appendix B. Definition and Use Table 2.2: Additional contaminants researched but with insufficient data to derive EIC/AGS/CL:AIRE GAC Substance CAS Synonyms 1-Methylnaphthalene 90-12-0 α-Methylnaphthalene 2-Methylnaphthalene 91-57-6 β-Methylnaphthalene 1,3,5-Trimethylbenzene 108-67-8 Mesitylene; sym-trimethylbenzene Carbazole 86-74-8 9-Azofluorene; dibenzopyrrole; diphenylenimine; diphenylenemide Dimethyl phthalate 131-11-3 Dimethyl 1,2-benzenecarboxylate Isopropyltoluene 99-87-6 4-Isopropyltoluene; p-Isopropyltoluene; 1-methyl-4-propan-2-ylbenzene; p-methylcumene; cymene n Butylbenzene 104-51-8 1-Butylbenzene; 1-phenylbutane sec Butylbenzene 135-98-8 2-Butylbenzene; 2-phenylbutane tert Butylbenzene 98-06-6 Pseudobutylbenzene; dimethylethylbenzene; trimethylphenylmethane 2.2 Use of EIC/AGS/CL:AIRE GAC The GAC have been derived in general accordance with the CLEA framework documents (see Section 3) and are intended to be used in the same way as the SGV. Guidance on the use of SGV is provided in the Environment Agency of England and Wales report entitled “Using Soil Guideline Values” (Environment Agency, 2009a) and although intended for the use of SGV, this guidance is also highly relevant to the use of the EIC/AGS/CL:AIRE GAC. The reader should therefore familiarise themselves with this guidance before using the GAC. The reader is also recommended to familiarise themselves with the SR2, SR3 and SR7 CLEA methodology framework documents (Environment Agency, 2009b, 2009c and 2008), the CLEA software handbook (Environment Agency, 2009d) and the Environment Agency of England and Wales CLR11 technical framework document for assessing and managing risks from land contamination (Environment Agency, 2004). 6
