摘要

Parabens, bisphenol A (BPA), triclosan, and triclocarban are recognized endocrine-disrupting contaminants (EDCs); and their occurrence in the environment has attracted increasing concern. Body size-dependent bioaccumulation, tissue distribution, trophic magnification, and maternal transfer of methyl-, ethyl-, propyl-, and butylparabens; 2-phenylphenol (PHP); BPA; triclosan; and triclocarban were investigated in freshwater fish of the Pearl River catchment, China. Most of the EDCs were detected in more than half of the biota samples, ranging from not detected to 6750ngg(-1) lipid weight, with median concentrations of 5 to 72ngg(-1) lipid weight. Livers generally contained the highest EDC levels (1609 +/- 1860ngg(-1) lipid wt, mean +/- standard deviation), followed in decreasing order by eggs (842 +/- 1317ngg(-1) lipid wt), belly fats (488 +/- 465ngg(-1) lipid wt), and dorsal muscles (240 +/- 239ngg(-1) lipid wt) of the wildlife. Body size-dependent bioaccumulation of the EDCs was observed in the freshwater fish, which varied according to species, tissue, and compound. The concentrations of triclosan, PHP, and BPA usually showed decreasing trends, whereas parabens mostly demonstrated increasing tendency with increasing fish weights, indicating effects of growth dilution and bioaccumulation, respectively. Potential biomagnification was shown by triclosan with trophic magnification factors of 3.0, 4.3, and 4.0 in liver, belly fat, and dorsal muscle, respectively. In addition, the potential of maternal transfer in the fish was primarily revealed for methyl- and propylparabens, PHP, triclosan, and BPA. Presence of the EDCs in the freshwater organisms of the Pearl River catchment warrants more attention considering the potential of trophic magnification and maternal transfer.
