Methods Rats were dosed orally and i.p. with a single dose of 14^C-deltamethrin （0.64 mg/Kg） body weight. The required dose was applied daily for 3 days. At the end of the experiment, selected organs, such as liver, kidney, fat, intestine, and blood were excised for radioassay of 14^C-content. Results Deltamethrin was almost eliminated from the body within 1-3 days. The main portion of 14^C-residues was extracted from urine （38%, 32%） and feces （20%, 24%） with a little amount remained in various organs. Conclusion The elimination and distribution of 14^C-radioactivity in rats treated orally and intraperitoneally signify that deltamethrin is bioavallable in urine and feces.展开更多
