Abstract.

The concentrations of chlorinated biphenyls (CBs), 1,1-bis(4-chlorophenyl)-2,2-dichloroethene (DDE), hexachlorobenzene (HCB), and the methylsulfonyl metabolites of CBs (MeSO2-CBs) and DDE (MeSO2-DDE) were determined in human plasma samples and in the fractions obtained by ultracentrifugation of plasma into very-low-density (VLDL), low-density (LDL), high-density (HDL) lipoprotein and lipoprotein depleted (LPDP) fractions (containing primarily albumin). The concentrations of triacylglycerols, cholesterol, phospholipids, and apolipoprotein B (apoB) were determined. The organochlorine compounds were associated with all fractions, but predominantly with the LPDP fraction. On an average 44% of CBs, 61% of MeSO2-CBs, 73% of DDE, 77% of MeSO2-DDE, and 45% of HCB were distributed in the LPDP fraction. A tendency to greater association of 3-methylsulfonyl substituted than of corresponding 4-methylsulfonyl substituted chlorobiphenyls to the LPDP fraction was noticed. Among the lipoprotein fractions, LDL was the main carrier of HCB, DDE and CBs. MeSO2-DDE was predominantly found in HDL and MeSO2-CBs were distributed equally among the LDL and HDL fractions. Calculating the concentrations of organochlorine compounds in relation to the content of apoB, the levels were about 10 times higher in VLDL than in LDL.
