“…As shown in Table 2, ∑HCH concentrations of the 26 sediment samples ranged from 0.56 to 232.60 ng/g dw, with an average of 19.59 ng/g dw. This was similar with the value in Dalian Bay (21.25 ng/g dw) (Li and Fu, 1998), higher than those in other two deltas in China, the Yangtze Delta (6.0 ng/g dw) (Liu et al, 2008) and Pearl River Estuary (0.68 ng/g dw) (Hong et al, 1999), but was lower than values in Liaodong Bay (68.6 ng/g dw) (Lu et al, 2008) and Tianjin Dagu Drainage Canal (87.74 ng/g dw) (Yang et al, 2005). Total DDT concentrations in the sediment samples in the study area ranged from undetectable to 52.03 ng/g dw, with an average of (2008) 7.20 ng/g dw.…”

The environmental occurrence, sources and risk factors of organochlorine pesticides (HCHs and DDTs) and their isomers or metabolites were studied using comprehensive surveys (including soil, surface water, groundwater and sediment sampling) conducted in the Yellow River Delta (YRD). HCHs and DDTs were all detected in multi environmental media. Compared with reported organochlorine pesticide values in China and abroad and with related environmental quality standards, the concentrations of HCHs and DDTs were generally at low levels in the YRD. Composition of OCPs (DDT metabolites and HCH isomers) showed that DDTs in the multiple environments of the YRD not only came from residues of dicofol but also from atmospheric deposition, while HCH pollution results from the historical usage of a mixture of technical HCH and lindane. Furthermore, the sum of Excess Lifetime Cancer Risk (∑ELCR) exposure to HCHs exceeded the generally acceptable risk level of 1.0E-06 recommended by the USEPA for carcinogenic chemicals.

“…The concentrations of the chlorinated pesticides are similar to literature data, 0.003 mg/kg for atrazine (Holvoet et al 2007) and 0.033 mg/kg for DDTs (Liu et al 2008). Higher concentrations of chlorinated pesticides are reported in the literature, e.g., 0.45 mg/kg for lindane (Villaverde et al 2008) and 0.81 mg/kg for the sum of 18 substances (Malik et al 2009), but even these extreme values remain far below the threshold for these substances.…”

Development and application of a methodology for screening, on the basis of the carcinogenic (H7), toxic for reproduction (H10) and mutagenic (H11) criteria of the latest European legislation, hazardous vs. non-hazardous sediments to be disposed of on land. Journal of Soils and Sediments, Springer Verlag, 2011, 11 (7), pp.1292-1307. <10.1007/s11368-011-0404-x>. Networks -RSMNs. Criteria H7, H10 and 11 are the only ones for which quantitative data are available in RSMNs. The second purpose was to apply, with a perspective of sediment management, the methodology to data sets from RSMNs. Materials and methodsThe data sets held up to 4,012 inland and 1,362 marine sediments for trace elements, and up to 2,774 inland and 952 marine sediments for organic micropollutants. Based on i) the trace elements analysed in RSMNs, ii) a literature review of aqueous solubility of the dangerous inorganic substances (EU list), and iii) a literature review of trace elements speciation in sediments, twelve inorganic dangerous substances with CRM properties were selected. For each substance, the threshold concentrations corresponding to a hazardous waste were then transformed into threshold total trace element contents. For the organic micropollutants, the list of dangerous substances considered was imposed by the content of RSMNs data bases, and the threshold values were directly taken from the waste regulation. The statistical distributions of the data set values were then compared to the threshold values.

Overall, only 0.08% of the samples may pose a CRM hazard due to their content in Ni, 0.2% for Cd, 0.26% for Cr, and 0.09% for Zn. The highest concentration of organic contaminant with CRM properties (62 mg/kg, benzo(a)pyrene) remains 16 times below the corresponding threshold value. ConclusionsNo CRM hazard results from the organic dangerous substances analysed in RSMNs. For the dangerous inorganic substances holding trace elements analysed in RSMNs, the possibility of CRM hazard exists at most for 0.6% of the samples considered. Taking into account the H7, H10 and H11 criteria in the assessment of the possible hazard caused by dredged sediments analyse...

“…Mean concentrations of HCHs, DDTs and HCB were 5.62 ± 4.35 ng/g dw, 2.43 ± 3.12 ng/g dw and 1.55 ± 4.17 ng/g dw, respectively (Table 2). When compared with other six major rivers in China, concentrations of OCPs in sediments of the Huaihe River were generally moderate and lower than those in sediments from the Daliao , Haihe (Yang et al, 2005), Yangtze (Liu et al, 2008) and Pearl Rivers (Fung et al, 2005), but higher than concentrations in sediments from the Songhua (He et al, 2008) and Yellow Rivers . Considering that agriculture is the primary source of OCPs, variation in concentrations in sediments among these rivers is mainly a result of regional differences in crops (Li et al, 2001).…”
