“…NPEOs with EO chains of 6-13 were the most abundant, and their profiles showed some difference from that of a standard NPEOs sample. This result may be associated with the low sewage treatment ratio in China; a similar profile was also found in fish from Changjiang River (11).…”

4-Nonylphenol (4-NP) is of particular concern because of its ubiquity in aquatic environment and its endocrinedisrupting effects in aquatic organisms. On the basis of its octanol-water partition coefficient (10 4.6 ), it has a potential to bioaccumulate in aquatic food webs. However, there are no reported field studies on the trophodynamics of 4-NP and its precursor, nonylphenol polyethoxylate (NPEOs) surfactants, in aquatic food webs. This study reports the trophodynamics of 4-NP and NPEOs (4 < s < 16) in a marine aquatic food web from Bohai Bay, North China. 4-NP and NPEOs (4 < s < 16) were determined in 14 marine species including plankton, benthic invertebrates, fish, and marine birds. This paper provides the first report on the occurrence of NPEOs with s > 5 in marine biota. Co-analysis of DDTs in all samples allowed a direct comparison of the bioaccumulation behavior of DDTs with that of NP and NPEOs. The lipid equivalent concentration of DDE and 2,2-bis(chlorophenyl)-1-chloroethylene (DDMU) increased with increasing trophic level, and the trophic level was determined by stable isotope ratios. The trophic magnification factors (TMFs) of DDE and DDMU were 3.26 and 3.7, respectively. Lipid equivalent concentrations of 4-NP and of all NPEOs did not exhibit a statistically significant correlation with trophic levels in the food web, and the TMF of NP was 0.83, which was similar to those of all NPEOs (0.45-1.22). These results show that in the studied aquatic food web, there was no trophic magnification for 4-NP and NPEOs, whereas DDE and DDMU biomagnified.

“…This result was within the ranges reported for different countries; Japan (50-1100 ng/L) (Hayakawa et al, 2001;Isobe et al, 2001), China (100-7,300 ng/L) (Shao et al, 2005), Taiwan (1800-10,000 ng/L) (Ding et al, 1999), the United States (<LOD to 640 ng/L) (Naylor et al, 1992), Canada (<LOD to 920 ng/L) (Bennie et al, 1997), Germany (10-400 ng/L) (Zellenr and Kalbfus, 1997), and Switzerland (<LOD to 480 ng/L) (Ahel et al, 2000).…”

Fecal sterols, nonylphenolic compounds (NPs), and polycyclic aromatic hydrocarbons (PAHs) were determined in surface water from Masan Bay and its adjacent rivers in February 2005. Concentrations of coporstanol (Cop), an indicator of fecal pollution, in surface water ranged from <10 to 13,853 ng/L, and concentrations of nonylphenol, the most toxic of the NPs, ranged from 10.2 to 481 ng/L, and concentrations of PAHs ranged from 8.61 to 223 ng/L. The concentrations of the compounds measured in this study were lower than or comparable to those at other locations in Korea and other countries. The contamination of Cop and PAHs in surface water was associated with the discharge from rivers passing through cities and/or industrial complexes. The NP contamination was associated with wastewater treatment plant (WWTP) effluents through outfalls as well as riverine discharge. Compared to ecotoxicological values, the concentrations of NPs from rivers, the mouths of rivers, and WWTP outfall areas exceeded guidelines, suggesting that hot spot areas may pose a potential risk to sensitive species.

“…Nevertheless, these compounds have not been effectively restricted in China. The NPEOs are found in various Chinese rivers at concentrations of up to 97.6 μg/L (Shao et al, 2005;Shen et al, 2005;Yu et al, 2009). In contrast to E2 and EE2, the estrogenic activity of 4-NP is very weak because 4-NP is a weak structural mimic of E2, but the levels of 4-NP can be extraordinary high to compensate (Soares et al, 2008).…”

Detection of estrogenic disrupting compounds (EDCs) in drinking waters around China has led to rising concerns about health risks associated with these compounds. There is, however, a paucity of studies on the occurrence and identification of the main compounds responsible for this pollution in the source waters. To fill this void, we screened estrogenic activities of 23 source water samples from six main river systems in China, using a recombinant two-hybrid yeast assay. All sample extracts induced significant estrogenic activity, with E2 equivalents (EEQ) of raw water ranging from 0.08 to 2.40 ng/L. Additionally, 16 samples were selected for chemical analysis by gas chromatography-mass spectrometry. The EDCs of most concern, including estrone (E1), 17β-estradiol (E2), 17α-ethinylestradiol (EE2), estriol (E3), diethylstilbestrol (DES), estradiol valerate (EV), 4-t-octylphenol (4-t-OP), 4-nonylphenols (4-NP) and bisphenol A (BPA), were determined at concentrations of up to 2.98, 1.07, 2.67, 4.37, 2.52, 1.96, 89.52, 280.19 and 710.65 ng/L, respectively. Causality analysis, involving comparison of EEQ values from yeast assay and chemical analysis identified E2, EE2 and 4-NP as the main responsible compounds, accounting for the whole estrogenic activities (39.74% to 96.68%). The proposed approach using both chemical analysis and yeast assay could be used for the identification and evaluation of EDCs in source waters of China.
