“…The Dagu River is another very important channel into which wastewater from domestic sources and from industries in Tianjin is discharged to be finally emptied into the Bohai Sea. Some toxic compounds, such as organochlorine pesticides (OCPs), xeno-estrogens (including 4-tert-octylphenol, 4-nonylphenol and bisphenol A) and mercury, have been reported in the previously studies in this area (Jin et al, 2004;Shi et al, 2005;Wan et al, 2005;Yang et al, 2005). However, few data are available to indicate the level of contamination of dioxin-like compounds in these rivers.…”

Total concentrations of compounds that can cause activation of the aryl hydrocarbon receptor (AhR) in extracts of river sediments from various locations in the Haihe and Dagu Rivers, Tianjin, China were determined by use of the in vitro H4IIE-luc cell line. AhR-active compounds were isolated from sediments by Soxhlet extraction, and the crude extracts were fractionated using a Florisil column into three Fractions. The response of samples was compared to the TCDD standard and expressed as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) equivalents (TCDD-EQs). Significant dioxin-like activity was observed in each sample. The TCDD-EQs in crude extracts of sediments (SCEs), as determined with the bioassay were 2-4 times greater than the sum of the TCDD-EQs of the eluent from fractions separated with a Florisil column. The results also showed that Fractions 2 and 3 contained most of the AhR-mediated activity. The results obtained by using the bioassay were compared with those of previous measurements of the concentrations of polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) and the structurally-similar AhR-active polychlorinated biphenyls (PCBs). It was determined that sediments from the Dagu River contained greater concentrations of TCDD-EQ than did sediments from the Haihe River except at Jingangqiao (location R3), which is associated with industrial activities in the adjacent densely populated area. The concentrations of TCDD-EQs, based on the EC 20 and the relative potency ranges, of SCEs ranged from 330 to 930 and 1200 to 13 900 pg TCDD-EQ g À1 dry wt in Haihe and Dagu Rivers, respectively.

“…Although DDT was also banned at the beginning of the 1980s in China, one of its metabolite residues, DDE, is still detected in aquatic environments due to its environmental persistence and the emergence of other sources such as the usage of dicofol, which contains DDT-related chemicals (25). The concentrations of DDTr's measured in the eggs of the common tern inhabiting Bohai Bay are summarized in Supporting Information Table 3.…”

“…Thus, p,p′-DDE in water and sediment is regarded as the source of p,p′-DDE in the eggs of common terns. The probability distribution of the p,p′-DDE concentration in the surface water of Bohai Bay was determined to have a log-normal distribution (p ) 0.5265) using the data set reported by Wan et al (25). The mean p,p′-DDE concentration and SD in water were calculated to be 1.19 ng/L and 0.62, respectively.…”

“…Although DDT was banned at the beginning of the 1980s in China, there are still p,p′-DDE residues in the water and sediment in Bohai Bay (25). Several papers have reported that the common tern is susceptible to p,p′-DDE, and its reproductive success decreased even at low concentrations of p,p′-DDE (25)(26)(27)(28). Common terns are not listed as an endangered species in China.…”

In this paper we first present a method of deriving site-specific water and sediment quality criteria of chemicals for protecting wildlife populations. The method has two steps: (1) identification of the threshold concentration in specific tissue corresponding to a population benchmark response and (2) extrapolating quality criteria on the basis of the bioaccumulation in tissue from the water or sediment (e.g., the bioaccumulation factor (BAF) and biota/sediment accumulation factor (BSAF)). The method was applied to derive 2,2-bis(chlorophenyl)-1,1-dichloroethylene (p,p‘-DDE) quality criteria of water and sediment of Bohai Bay, China, for common tern populations. The benchmark concentration in eggs of the common tern was determined to be 663 ng/g wet weight from the relationship curve between concentration (biotic burden in eggs) and the intrinsic rate of population increase (r) calculated by an age-structured matrix approach. The p,p‘-DDE concentra tions (mean 58.79 and ranging from 13.14 to 326.60 ng/g wet weight) measured in common tern eggs (n = 35), collected from the Beidagang wetland on the coast of Bohai Bay in China, and those in surface water or sediment from literature values were combined to estimate the probability distribution of BAF and BSAF using the Monte Carlo method. Finally, the marine water and sediment quality criteria of p,p‘-DDE in Bohai Bay were estimated to be 4 ng/L and 1.9 ng/g dry weight, respectively.

“…Persistent organic pollutants (POPs) that are released from the intensive agricultural and industrial activities have stressed the surrounding coastal ecosystems and have been regarded as one of the pollutant sources impacting the health of marine coastal environment and organisms (Fung et al 2004;Liu et al 2012). Previous studies have showed that the increased POPs along the Yantai coast could cause potential risk for the seafood (Wan et al 2005a;Liu et al 2008;Leng et al 2009). SB is an important aquaculture bay, which supports the seafood market in Yantai and adjacent cities.…”

To evaluate the contamination of organochlorine pesticides (OCPs) in marine organisms and their potential health risk on consumers in the northern Yellow Sea of China, mollusks, wild shrimps, and crabs were collected from the Yantai coast, and the OCP contents in the samples were analyzed and compared. The results indicate that all the samples have been contaminated by OCPs, and OCP concentrations varied in individual species and in sampling sites. Among the studied OCPs, ∑HCH and ∑DDT concentrations ranged from 0.91 to 13.92 ng g −1 and from 10.16 to 411.19 ng g −1 , respectively. Meretrix was highly enriched with HCHs, while the highest DDT concentration was found in Crassostrea. For the OCP isomers, β-HCH was the predominant isomer of HCHs, and p,p′-DDE concentration was much higher than other isomers of DDTs. The concentrations of other OCPs (HCB, t-CHL, endrin, and mirex) were relatively low. For the shrimp and crab samples, Alpheus distinguendus samples accumulated a higher level of HCHs but lower DDTs than Oratosquilla aratoria and Carcinoplax vestitus in all sampling areas. HCHs in the samples of contrast area were not significantly lower than that of the sewage outfall area and port area, whereas DDTs in the samples of contrast area were relatively lower than that of the other two areas. Generally, all the OCP contents in the samples are in the range of the edible hygienic criteria except the total concentration of DDTs in Crassostrea.
