OBJECTIVE: To study contamination of endocrine disrupting chemicals (EDCs) in aquatic environment of Qiantang River. METHODS: Carp vitellogenin (VTG) content in serum and ethoxyresorufin-o-deethylase (EROD) activity in liver of wild crucian, pesticide content including organic cholorine, organic phosphorus and pyrethroid in its muscle from 7 monitoring sites including Zhangtan (ZT), Jiekou (JK), Jiangjunyan (JJY), Yandongguan (YDG), Tonglu (TL), Fuyang (FY) and Yuanpu (YP) in Qiantang river were detected. And chemical analysis of water quality was carried on in four sites. RESULTS: EROD activity in crucian from ZT, JJY, FY and YP [(23.51 +/- 4.17), (16.79 +/- 7.39), (18.74 +/- 5.16), (18.65 +/- 8.86) nmol x g(-1) pro x min(-1), respectively] was significantly higher than that of control ((7.84 +/- 2.42) nmol x g(-1) pro x min(-1)), and VTG content in wild crucian from ZT, TL, FY and YP [(1.536 +/- 0.521), (16.404 +/- 13.579), (19.672 +/- 16.354) and (17.079 +/- 18.397)] microg/ml, respectively) was significantly higher than that of control [(0.400 +/- 0.099) (microg/ ml]. No significantly difference in biomarkers was observed between other site and control. From high to low, in total organophosphorus, it was followed as: TL, YDG, YP, FY, QZ, JK, JJY (EPN was up to 2695.64, 611.96 microg/kg in TL and YDG, respectively). In total organochlorine: TL, YP, YDG, FY, QZ, JK and JJY (tetradifon content in muscle of wild crucian from TL was up to 3962.17 microg/kg). For pyrethroid pes...
