Abstract: | Abstract Adipose tissue, milk and blood from Dutch citizens have been investigated for the occurrence of organochlorine compounds since 1968. In this paper, median values for HCB, α-HCH, β-HCH, γ-HCH, β-Hepo (heptachlorepoxide), dieldrin, p.p′-DDE, o.p′-DDT, TDE and PCBs (first determined by the perchlorination method, later by a selection of individual congeners) are given. Time trends, influence of age and sex of the donors, changes in concentrations of milk during lactation, the possible effect of life-style, and statistical evaluation of the data collected over the past twenty years will be discussed. PCBs and p.p′-DDE occur in the highest concentrations in all tissues investigated, followed by HCB and β-HCH. Especially the p.p′-DDT levels decreased dramatically over the years of the investigation. Blood/fat accumulation factors were derived; they decrease in the order PCBs?p.p′-DDE >β-HCH?HCB > β-Hepo?dieldrin > α-HCH?γ-HCH. |
