“…Specifically, the K OC value for OP determined in the present study was lower than that measured in the Elbe River, Germany (log K OC ¼ 5.52 AE 0.04) [11] and in the Jamaica Bay of the United States (log K OC ¼ 5.18 AE 0.28) [16], but higher than that measured in three English rivers (log K OC ¼ 3.91 AE 0.24) [14]. The log K OC value for NP in the Pearl River was close to that measured in the other studies.…”

Abstract-The distribution of endocrine-disrupting chemicals (EDCs) and its relationship with dissolved and particulate organic carbon (DOC and POC) was investigated in selected rivers of the Pearl River Delta, South China. The aqueous concentrations (average; ng/L) and particulate concentrations (average; ng/g, dry wt) for 4-tert-octylphenol (OP), 4-nonylphenol (NP), bisphenol A (BPA), and estrone (E1) were in the ranges of not detectable to 153 (31.8), 276 to 2,457 (1,178), 8.4 to 628 (161), and less than 1.5 to 11.5 (3.2), respectively, and 4.4 to 402 (98.1), 342 to 12,053 (4,922), 12.3 to 758 (128), and not detectable to 14.4, respectively. The highly significant correlation of EDCs with DOC and POC, and the similar regression slopes, implied the critical importance of DOC and POC on the distribution, transport, and fate of EDCs in the aquatic environment. The in situ particle-water partition coefficients (log K OC ) for OP (4.89 AE 0.41), NP (5.05 AE 0.33), and BPA (4.34 AE 0.50) were close to those reported by other field studies, but one to two orders of magnitude higher than those predicted with n-octanol-water partition coefficient (K OW ). The higher K OC values were attributed to the combined effects of low EDC concentrations, nonlinear sorption, and heterogeneity of POC and DOC. Moreover, a regression between in-situ K OC and K OW for phenolic xenoestrogens was observed (log K OC ¼ 0.625 Â log K OW þ 2.28, r 2 ¼ 0.99), suggesting that hydrophobicity contributed predominantly to the overall sorption of OP, NP, and BPA.

“…Stimulatory effects of M. aeruginosa by low concentration of NP (0.02-0.2 mg/L) might be the effect of hormesis, and further studies are needed to investigate the possible relationship between such hormesis effect with cyanobacteria bloom. The finding of this study that NP enhanced growth and toxin production of M. aeruginosa at low concentrations of 0.02-0.2 mg/L that can be found in natural freshwaters Bennie, 1999;Johnson et al, 1998;Kvestak and Ahel, 1994) might imply that low concentration of NP favor survival of toxic M. aeruginosa in the field. At the mean time, microcystin releasing also influenced by NP hint us that NP and may include other POPs have taken part in the process of microcystin synthesis and releasing.…”

Abstract. Sediment and mysids from the Scheldt estuary, one of the largest and most polluted estuaries in Western Europe, were analyzed for a number of contaminants that have shown to possess endocrine-disrupting activity, i.e. organotins, polybrominated diphenyl ethers (PBDEs), hexabromocyclododecane (HBCD), tetrabromobisphenol A (TBBPA), nonylphenol ethoxylates (NPE) and transformation products nonylphenol (NP) and nonylphenol ether carboxylates (NPEC). In addition, in vitro estrogenic and androgenic potencies of water and sediment extracts were determined. Total organotin concentrations ranged from 84 to 348 ng/g dw in sediment and 1110 to 1370 ng/g dw in mysid. Total PBDE (excluding BDE-209) concentrations ranged from 14 to 22 ng/g dw in sediment and from 1765 to 2962 ng/g lipid in mysid. High concentrations of BDE-209 (240-1650 ng/g dw) were detected in sediment and mysid (269-600 ng/g lipid). Total HBCD concentrations in sediment and mysid were 14-71 ng/g dw and 562-727 ng/g lipid, respectively. Total NPE concentrations in sediment were 1422 ng/g dw, 1222 ng/g dw for NP and 80 ng/g dw for NPEC and ranged from 430 to 1119 ng/g dw for total NPE and from 206 to 435 ng/g dw for NP in mysid. Significant estrogenic potency, as analyzed using the yeast estrogen assay, was detected in sediment and water samples from the Scheldt estuary, but no androgenic activity was found. This study is the first to report high levels of endocrine disruptors in estuarine mysids.Capsule. Field populations of mysid shrimp (Neomysis integer) of the Scheldt estuary (The Netherlands) are exposed to high concentrations of endocrine disruptors.
