摘要

The acute photoactivated toxicity of fluoranthene to the glochidial larvae of the paper pondshell, Utterbackia imbecillis, was characterized in the laboratory using three sets of experiments. Toxicokinetic studies revealed that glochidia rapidly bioac- cumulated fluoranthene, reaching an apparent steady state in 4 h. Based on a two-compartment model, uptake(K_u)and depuration (K_d)rate constants were 1394 ml/g/h and 0.769/h, respectively. However, experimental data suggested the presence of a fast and the overall sensitivity of with a K_d of 0.290 and 0.031/h, respectively.
