Contributions to ecological chemistry, CXIV1. Fate of 2,2'-dichlorobiphenyl-14C in rats upon long-term feeding.


Each of five male and five female rats was orally dosed with 49.2 mug 2,2'-dichlorobiphenyl-14C daily for 42 days. After 36 days, the radioactivity in the body reached a plateau level, and male rats had excreted 84.5% of the applied radioactivity, females 87.9%; the residues in most organs were below 0.2 mg/kg. The daily excreted radioactivity after 50 days… (More)
