摘要
Bioconcention of tetrachlorobenzene(TeCB) in Chlorella marine, Nannochloropsis oculata,Pyramidomonas sp., Platymonas subcordiformis,and Phaeodactylum tricornutum;and toxicity of TeCB to the marinealgae were tested.Values of bioconcentration potential parameters,including uptake rate constant k1,elimination rate constant k2 and bioconcentration factor BCF, were obtaintal not only from the time course of TeCB uptake by the marine algae by using a bioconcentration model,but also from the acute toxicity test data for percent inhibition P (%) ~ exposure concentration of TeCB-time by using a combined bioconcentration and probability model. The results showed good relationship between k1(TOXIC) and k1(UPTAKE),and k2(TOXIC),k2(UPTAKE), and BCFD(TOXIC) and BCFD(UPTAKE). Especially,the values of BCFD(TOXIC) were well consisten with those of BCFD(UPTAKE).
