    ABSTRACT: The six heavy metal concentrations (Cr, Cr, As, Cd, Cu, Zn and Pb) in water samples collected from five reservoirs of Liao River Basin were studied. The health risk assessment for heavy metals pollution in reservoirs was conducted based on the environmental health risk assessment model recommended by U. S. Environmental Protection Agency. The results showed that the average concentrations of CrCuZnAsCd and Pb in five reservoirs of Liao River Basin were 3.36, 1.03, 2.70, 1.23, 0.02 and 0.03 μg·L-1respectively. In fact, these heavy metals concentrations were obviously lower than the Standard of National Drinking Water in China (GB 5749—2006). The results also showed that the metal carcinogenic risk was relatively high in this region. The order of the risk level of carcinogenic metals was Cr>As>Cd. The highest carcinogenic risk was from Cr, with the risk for adults ranging from 4.50×10-5~7.53×10-5 a-1 and the risk for children ranging from 6.29×10-5 to 1.05×10-4 a-1. The health risk levels caused by non-carcinogenic metals ranging from 10-13 to 10-10 a-1 were lower than the acceptable range suggested by International Commission on Radiological Protection (ICRP) and the order of the risk level of non-carcinogenic metals was Cu>Zn>Pb. The total health risk of heavy metals for adults ranging from 1.07×10-4 to 1.72×10-4 a-1 and for children ranging from 1.49×10-4 to 2.40×10-4 a-1 exceeded the accepted level of 5×10-5 a-1 as suggested by ICRP. The health risk levels of carcinogenic metals were significantly higher than those of non-carcinogenic metals in the reservoirs for Liao River Basin.

    ABSTRACT: Pentachlorophenol (PCP) is frequently detected in the aquatic environment and has been implicated as an endocrine disruptor in fish. Here, 4-month-old zebrafish (Danio rerio) were exposed to one of four concentrations of PCP (0.1, 1, 9 and 27 µg/L) for 70 days. The effects of PCP exposure on plasma thyroid hormone levels, and the expression levels of selected genes were measured in the brain and liver. PCP exposure at 27 µg/L resulted in elevated plasma thyroxine concentrations in male and female zebrafish, and depressed 3, 5, 3'-triiodothyronine concentrations in males only. In both sexes, PCP exposure resulted in decreased mRNA expression levels of thyroid stimulating hormone β-subunit (tshβ) and thyroid hormone receptor β (trβ) in the brain, as well as increased liver levels of uridine diphosphoglucuronosyl transferase (ugt1ab) and decreased deiodinase 1 (dio1). We also identified several sex-specific effects of PCP exposure, including changes in mRNA levels for deiodinase 2 (dio2), cytosolic sulfotransferase (sult1 st5), and transthyretin (ttr) genes in the liver. Environmental PCP exposure also caused an increased malformation rate in offspring that received maternal exposure to PCP. The present study demonstrates that chronic exposure to environmental levels of PCP alters plasma thyroid hormone levels, as well as the expression of genes associated with thyroid hormone signaling and metabolism in the HPT axis and liver, resulting in abnormal zebrafish development.

    ABSTRACT: Seldom monitored trace element concentrations in road dusts colleted from Shihezi City were studied. A total of 32 sampling stations were selected. The concentration of 10 seldom monitored trace elements (B, Be, Bi, Co, Ga, Li, Sb, Sn, T1, V) were determined. Their pollution degree and source identification were analyzed by using Geoaccumulation Index, correlation coefficient and principal factor analysis. The results indicated that the mean concentrations of Li, Be, B, V, Co, Ga, Sn, Sb, T1 and Bi were 24. 91, 1.68, 41. 11, 72. 66, 13. 58, 36. 26, 3.64, 3.37, 0. 42 and 0.52 mgkg-1, respectively. The mean concentrations of Li, T1, Co, Be, B, and V were lower than or similar to the soil background values of Xinjiang province. However, the mean concentrations of Ga, Sn, Sb and Bi were higher than the background values of Xijiang province and world soil. The results of Geoaccumulation Index indicated that the pollution degrees of Li, Be, B, V, Co, Ga and T1 were zero, and belonged to the category of non-pollution. However the pollution of Sb, Bi and Sn were considerably serious, and their pollution grades were 2, 1 and 1 respectively. The source of SMTEs in road dusts of Shihezi City was identified by multivariate statistics (principal component analysis and correlation analysis). The results showed that Sb, Co, T1 and Bi mainly originated from human activities, Li, Be, B, V represented natural sources, while Sn and Ga have the mixed sources of nature and human activities.

    ABSTRACT: Heavy metals have been accumulated in sediment after impoundment in the Three Gorges Reservoir (TGR). In order to evaluate the risk of biomagnification of heavy metals, we investigated the trophic relationships and heavy metal concentrations in fish from a tributary within TGR. Sixteen fish species were collected from Daning River, and concentrations of eight heavy metal elements (Cr, Ni, Cu, Zn, Pb, Cd, As, and Hg) were determined, as well as the ratios of stable carbon and nitrogen isotopes. Results showed that most heavy metal concentrations were low in TGR, but changed significantly among different species. The delta13C values varied significantly among different groups (-22. 80 per thusand - 28. 97 per thusand) ; while the delta15N values (6. 41 per thusand - 13. 88 per thusand) varied based on their feeding types. A significantly trophic level-dependent increase was found in concentrations of Hg, indicating an overall biomagnification of Hg; but the increase of Hg concentration per trophic level was lower than that in previous studies. No tendency towards trophic-level enrichment was observed for other elements studied. However, a much higher heavy metal concentration was observed in small-sized fish samples, indicating a potential risk in environment.

    ABSTRACT: A total of 28 surface sediment samples (at the top 0-5 cm layer) were collected from the Three Gorges Reservoir of Yangtze River. The content of polybrominated diphenyl ethers (PBDEs) in sediments was measured with Varian GC-MS (NCI). The results showed that sigma26 PBDEs and BDE209 both had a low concentration in sediments, with a mass concentration of 35.24 pg x g(-1) and 11.92 pg x g(-1), respectively. Among the 26 PBDEs, BDE28, 47, 77 and 99 were the most predominant sigma26 PBDEs congeners. The highest concentrations of sigma26 PBDEs and BDE209 were detected in the sediment samples collected from Long River, with geometric mean of 146.07 and 502.63 pg x g(-1), respectively. A significant correlation was found between sigma26 PBDEs and BDE209, indicating that they might have the same pollution source. The concentrations of sigma26 PBDEs and BDE209 in the sediment were in the same order of magnitude with those reported on background levels in sediments of remote lakes in other countries, which shows the toxic biological effects on aquatic biota and potential risk due to sigma26 PBDEs and BDE209 contamination in sediments are negligible.

    ABSTRACT: The humic acid (HA) and nonhydrolyzable carbons (NHC) were isolated from three river sediment samples (1, 2, 3) from the rivers in the Tongzhou district of Beijing and four soil samples(4, 5, 6, and 7) from the surface soils in the vicinity area of Tianjin near Bohai Bay, respectively. The isolated HA and NHC fractions were also characterized using elementary analysis, X-ray photoelectron spectroscopy (XPS), solid state 13C cross-polarization and magic angle spinning nuclear magnetic resonance spectroscopy (13C NMR), and Fourier transformed infrared spectroscopy (FTIR). The results showed that NHC had lower H/ C and O/C atomic ratios than HA from the same source. The sum of surface O-containing groups accounted for 7.6%-10.7% and 40.9%-46.7% in NHC and HA samples, respectively. 13C NMR and FTIR spectra of the NHC samples revealed a large contribution of alkyl carbon and aryl carbon. In addition, the NHCs isolated from soils had higher content of aromatic carbon than the NHC form river sediments. Systematic characterization showed that the NHC samples were more condensed and hydrophobicity than the HA samples.

    ABSTRACT: CH4 and CO2 are important greenhouse gases, playing a very important role in greenhouse effect. In order to estimate the current situation of source and sink of main greenhouse gases in Baiyangdian wetland and evaluate the influences of wetland system to the greenhouse effect of North China, static closed chamber-gas chromatogram method was adopted to study the space-time variation characteristics of N2O, CH4, and CO2 emission fluxes in Baiyangdian wetland. The analysis results indicate: the lake wetland which was abundant in organic matters and nutritive salt was an important greenhouse gases emission source. During one year of observation, it was found out that the fluxes of N2O, CH4, and CO2 of Baiyangdian wetland posses a very high time variability, with the range of variation being-0.08~0.33 mg·m-2·h-1, -5.40~328.65 mg·m-2·h-1 and -814.06~2934.93 mg·m-2·h-1. The emission fluxes of N2O, CH4, and CO2 reaches to maximum in summer, respectively being 62.09%, 92.15% and 87.04% of the annual total emission flux, The lakeside was a core area of N2O, CH4 emission, with annual average emission flux respectively reaching up to 0.11 mg·m-2·h-1 and 40.86 mg·m-2·h-1. Although the main emission area of CO2 was land, the emission flux of lakeside, with annual average emission flux being 692.35 mg·m-2·h-1, was also very high, ranking only second to land, the lakeside area of Baiyangdian wetland was only 12.60% of the whole lake wetland area, but the emission loads of N2O, CH4, and CO2 were respectively 26.51%, 43.96% and 23.76% of the total emission load, which explains that the lakeside wa- leading the greenhouse gases emission of Baiyangdian wetland.

    ABSTRACT: Eighty-one surface water samples were collected from 3 tributaries of the Yangtze River in different periods. Contents of 28 PCB congeners in surface water samples were measured using Varian CP3800/300 GC-MS/MS technique. PCB8, 18, and 28 are the most predominant PCB congeners in the samples from tributaries. The measured level of PCBs in the samples from the Tuo river, downstream of Ouchi River and Songlihongdao tributary were 1.96-2.59 ng x L(-1), 1.84-2.54 ng x L(-1) and 1.52-2.38 ng x L(-1). The average concentrations of PCBs in the samples were lower than USEPA criterion continuous concentration (14 ng x L(-1)), which were also in the same order of magnitude of those reported with lower levels in European and American countries. The estimated cumulative cancer risk for the local residents who drink water from tributaries were 0.15 x 10(-7)-0.26 x 10(-7), which shows that cancer risk are negligible due to PCBs contamination in these samples.

    ABSTRACT: Forty-seven surface water samples were collected from the main stream and 22 tributaries in area of the Three Gorges Reservoir, 15 phenolic compounds in these samples were analyzed using GC/MS. The results showed that the concentrations of phenolic compounds in the samples from the main stream and tributaries were 52.47 ng x L(-1) and 87.99 ng x L(-1), respectively. The concentrations of non-chlorinated phenols were higher than those of chlorinated phenols in the main stream and tributaries, and so the non-chlorinated phenols were the predominant compounds in these surface water samples. Phenol, o-cresol and 2-nitrophenol were the predominant compounds accounted for 79.1%, 3.7% and 3.6% in the samples from the main stream, respectively. Phenol, o-cresol, 2,6-dichlorophenol and 2-nitrophenol were the main compounds accounted for 77.5%, 5.4%, 3.8% and 2.2% in the samples from the tributaries, respectively. As compared the concentrations of phenol and 2-nitrophenol with the standard limits in The National Environmental Health Risk List, the levels of phenol and 2-nitrophenol were much lower than the standard limits, suggesting negligible risk of phenol and 2-nitrophenol in these samples.

    ABSTRACT: A geochemical study of Beijiang River sediments was carried out to analyze the concentrations, distribution, accumulation and potential sources of the seldom monitored trace elements (SMTEs: Sc, V, Co, Ga, Y, Sn and Sb). The mean concentrations of Sc, V, Co, Ga, Y, Sn and Sb were 8.2, 60.3, 9.6, 17.2, 28.6, 85.6 and 39.0 mg/kg, respectively. The concentrations of the SMTEs, together with their spatial distribution showed that the SMTEs were mainly due to anthropogenic inputs from the metal smelting industries and local mining activities in the upper region of the river. The assessment by geoaccumulation index indicates that Sc, V, Co, Ga and Y are at the unpolluted level, Sn is at the 'strongly contaminated' level, and Sb is at the 'extremely contaminated' level. The pollution level of the SMTEs is: Sb > Sn > Y > Ga > Co > V > Sc. The results of correlation analysis and principal component analysis indicated the Sn and Sb were positively correlated with each other, indicating a common source in sediments. In conclusion, our results indicate that the sediments in Beijiang River have been severely contaminated by Sn and Sb.

    ABSTRACT: Violent disturbance are occurring in Haihe River basin due to a large number of human activities. To investigate the PBDEs pollution status and their distribution character, 48 surface sediment samples (at the top 0-5 cm layer) were collected from 14 principal tributaries in Haihe River basin. The contents of 27 PBDEs congeners in sediments were measured using Varian CP3800/300 GC-MS/ MS technique. The measured level of PBDEs ranged from 0.06 to 2.10 ng g(-1), the highest concentrations of PBDEs were detected in the sediment samples from Tuhai River, with geometric mean 2.10 ng x g(-1). BDE184, 207, 197, 191, 183 and 156 were the most predominant PBDE congeners, with their concentrations accounting for 40% of the total PBDEs concentration observed in the samples. Whereas BDE15, 28 and 47 were the primary PBDE congeners in the sediments from other rivers, with their concentration accounted for over 22% of the total PBDEs concentration. The PBDEs levels monitored in the present study were compared to those reported recently for districts located in other countries. The concentrations of PBDEs in the sediment samples were in the same order of magnitude of those reported on background levels in remote lakes sediment in European and American countries, which shows low-level PBDEs contamination in sediments.

    ABSTRACT: In order to survey platinum group elements (PGEs) contamination in central urban area of Beijing, dust samples were collected from the second ring road in December 2009. The road samples were digested with aqua regia and separated and purified with cation exchange resin, and the resulting solutions were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The results showed that the concentrations of Pd, Pt and Rh in road dust ranged from 17.40-458.75 ng x g(-1) (126.66 ng x g(-1)), 10.04-182.89 ng x g(-1) (65.25 ng x g(-1)), 4.00-68.04 ng x g(-1) (22.67 ng x g(-1)) respectively. In comparison with international cities, Pd and Rh concentrations in Beijing road dust were middle level and Pt concentration was lower. Pd concentration was rapidly increased in recent years. The concentrations of PGEs in four locations of the second ring road were arranged in the following order: West approximately East > North > South, which were controlled with the traffic intensity. Size partitioning indicated that the 0.125-0.25 mm fraction had the higher PGEs concentrations than other fractions and the < 0.063 mm fraction had the lower PGEs concentration. These data suggest that autocatalyst PGEs flux estimates into the environment will be significantly underestimated if only a fine grain size fraction (< 0.063 mm) is analyzed.
