Bone Pb in temporal<br />

bone, cortical part <strong>of</strong><br />

the mid-femur, and<br />

pelvic bone from<br />

120 female and 120<br />

male adult cadavers.<br />

AAS.<br />

Bone Pb in temporal<br />

bone, cortical part <strong>of</strong><br />

the mid femur, and<br />

pelvic bone from<br />

82 child cadavers.<br />

Nitric acid digestion,<br />

AAS.<br />

Pb in rib bone and hair<br />

from 59 cadavers, aged<br />

1-87 yrs. Perchloric<br />

acid digestion, AAS.<br />

76 cadavers, age range<br />

0 to 83 yrs.<br />

Geometric means:<br />

Males: Pelvic 1.95 ± 1.00 (µg/g, wet weight), mid-femur 4.75 ± 2.53, temporal 6.24 ± 3.17.<br />

Females: Pelvic 1.41 ± 0.74 (µg/g), mid-femur 3.14 ± 1.89, temporal 5.00 ± 2.66.<br />

(values in µg/g wet weight)<br />

Found cortical lead ><br />

trabecular lead. Limited<br />

difference in Pb <strong>for</strong> younger<br />

males and females; much<br />

higher Pb in bones <strong>of</strong> men<br />

>50 yr old compared with<br />

women<br />

Negligible difference <strong>for</strong> 0 to<br />

1 yr olds, <strong>for</strong> pre-school<br />

children (1-6 yrs) and <strong>for</strong><br />

10 to 20 yr olds; mean values<br />

<strong>for</strong> cortical bones showed<br />

higher Pb concentrations than<br />

trabecular bone; mean Pb in<br />

the mid femur and temporal<br />

bone was not statistically<br />

different <strong>for</strong> each <strong>of</strong> three<br />

age groups.<br />

Bone Pb 3.0 (±1.5) µg/g (n = 54). Small increases to age 50 yrs<br />

in rib bone. Number <strong>of</strong><br />

samples <strong>for</strong> each age group<br />

not stated.<br />

Age 0 yrs (1.25 µg/g wet weight) to 59 yrs (4.5 µg/g) after which there was a decrease<br />

(~2.5 µg/g). For the age range 10-49 yrs, there was no significant difference in mean<br />

values <strong>of</strong> 2.8 to 3.1 µg/g.<br />

Found no significant gender<br />

difference but levels in 1986<br />

were significantly lower than<br />

in 1976.
