## Abstract The toxicokinetics of benzo(a)pyrene (BaP) and 3โhydroxybenzo(a)pyrene (3โOHBaP) were assessed in 36 male SpragueโDawley rats injected intravenously with 40 ยตmolโkg^1^ of BaP to explain the reported atypical urinary excretion profile of 3โOHBaP. Blood, liver, kidney, lung, adipose tissu
3-hydroxy-benzo(a)pyrene (3-OH-B(a)P) and mutagenic activity in rat urine were determined after the oral administration of benzo(a)pyrene given in three repeated doses of 10, 20 and 50 pmol kg-'. The procedure for the determination of 3-OH-B(a)P consisted of enzymic hydrolysis, separation and HPLC-a
