Mean body burdens of p,p'-DDE among Inuit mothers were 3- to 11-fold higher than among the Uppsala mothers [ 13, 50].
According to the National Human Adipose Tissue Survey (NHATS), the mean TCDD body burden for U.S. men was 4.22 ppt compared with a mean TCDD level of 4.6 ppt in the comparison group (Orban et al. 1994).
Cadmium is unique among the common heavy metal pollutants in that urinary cadmium is a biomarker of lifetime exposure, providing a means for assessing total body burden of cadmium[ 14, 15].
Thus, after long-term low-level exposure, BCL measurement offers a useful means to estimate the total body burden of cadmium, as it is closely related to the total body burden of cadmium in the general population [ 4, 35, 38].
This is indicated by significantly shorter mean half-life at higher blood lipid TCDD concentrations (> 700 ppt) and higher TCDD mass in the body fat (> 7,000 ng) compared to means for the paired, lower body burden groups (Table 1).
This means that only 1/20th of the body burden of Hg is confined to the vascular space.
The predominant congener found in blood was BDE-47; it contributed 51 100% of the body burden in our subjects (mean, 85%).
Alternately, this means that, at steady state, partitioning of the body burden of Hg between the tissue regions associated with the central and peripheral compartments is about 2 1.
Besides, the Cheras respondents also had low urinary Cd which means that they had the risk of increasing body burden of Cd.
The observed NS digestive gland mean concentration of 831.85 ng Zn/mg tissue is similar to the body burden observed (approx. 200 500 µg Zn/g tissue) in effluent treatments resulting in mortality and reduced fecundity in Lymnaea palustris [9].
