Uptake of polycyclic aromatic hydrocarbon compounds by the gills of the bivalve mollusk Elliptio complanata.

abstract：:Embryonic zebrafish were used to compare the uptake and metabolism of six polybrominated diphenyl ether (PBDE) congeners (BDEs 28, 47, 99, 100, 153, and 183) and identified metabolites from static exposures at 24 and 120 h postfertilization (hpf). An inverse relationship was observed between uptake of PBDEs and their ...
