Bioconcentration and tissue distribution of perfluorinated acids in rainbow trout (Oncorhynchus mykiss).
Rainbow trout (Oncorhynchus mykiss) were exposed simultaneously to a homologous series of perfluoroalkyl carboxylates and sulfonates in a flow-through system to determine compound-specific tissue distribution and bioconcentration parameters for perfluorinated acids (PFAs). In general, PFAs accumulated to the greatest extent in blood > kidney > liver > gall bladder. Carboxylates and sulfonates w...

15 صفحه اولAnthracene Bioconcentration in Rainbow Trout during Single-compound and Complex-mixture Exposures
Rainbow trout were exposed for 72 h to [ 14C]anthracene alone and [ I4C]anthracene in an oil shale retort water. Tissue levels of [I4C]anthracene were analyzed at 24, 48 and 72 h to determine non-steady-state bicconcentration factors (BCFs), and uptake and depuration rates were calculated from anthracene disappearance in exposure waters and metabolite appearance in depuration waters. Uptake rat...
متن کاملEvaluation of estrogenic activities of aquatic herbicides and surfactants using an rainbow trout vitellogenin assay.
Estrogenic potencies of four herbicides (triclopyr, 2,4-dichlorophenoxyacetic acid (2,4-D), diquat dibromide, glyphosate), two alkylphenol ethoxylate-containing surfactants (R-11 and Target Prospreader Activator (TPA)), and the binary mixture of surfactants with the herbicides were evaluated using an in vivo rainbow trout vitellogenin assay. Juvenile rainbow trout exposed to 2,4-D (1.64 mg/l) f...
متن کاملPredicting the bioconcentration of fragrance ingredients by rainbow trout using measured rates of in vitro intrinsic clearance.
Bioaccumulation in aquatic species is a critical end point in the regulatory assessment of chemicals. Few measured fish bioconcentration factors (BCFs) are available for fragrance ingredients. Thus, predictive models are often used to estimate their BCFs. Because biotransformation can reduce chemical accumulation in fish, models using QSAR-estimated biotransformation rates have been developed. ...
