Abstract
Polychlorinated-biphenyl (1336363) (PCB) residues and chlorinated hydrocarbon pesticide residues were assayed in 723 plasma samples collected from healthy volunteers, who resided in a single southeastern county and were not occupationally exposed to pesticides. As expected, p,p'DDT (50293) and DDE residues were almost universal. Residues of DDD (72548) (84 percent), and dieldrin (60571) (63 percent) were also common. PCB residues were found in 43 percent, ranging up to 29 parts per billion. Significant age effects, not always linear, were observed for all residues except dieldrin and PCB. Ethnic differences were marked for every residue and ethnic residence interactions were significant for all except dieldrin. Independent residential effects were observed for all except DDE and dieldrin. Sex differences were noted only for p,p'DDT and DDE. PCB residues were more frequent and higher in whites and urban residents. Residues were rare (4.1 percent) in rural blacks. Likely urban exposure routes of PCB include polluted air and contaminated water. Other similar occult pollution problems are discussed.
