“…The HCHs concentration in the soil of JRW was a little higher than that in QBC, but they were almost in the same level. In contrast with other regions, the mean values of HCHs concentration in the soil of JRW and QBC were comparable to those reported in Tibet (0.18-5.38 ng/g) (Fu et al, 2001) and Shanghai (2.41 ng/g) ) and lower than those in Beijing (median 5.25 ng/g) and Tianjing (median 7.03 ng/g) (Lv et al, 2010), but higher than James Ross Island (0.49-1.34 ng/g) (Klá nová et al, 2008) and Wolong Natural Reserve, China (0.23-0.80 ng/g) ). In the soil of JRW, d-HCH was dominant in HCHs, with mean value of 0.80 With regards to DDTs, the concentrations ranged from 1.77 to 25.03 ng/g and 1.53 to 53.26 ng/g for DDTs (sum of o,p 0 -DDT, p,p 0 -DDE, p,p 0 -DDD and p,p 0 -DDT) in the soil of JRW and QBC, respectively.…”

“…Organochlorine pesticides (OCPs) are an important class of environmental organic pollutants that are commonly found in all regions of the world, even in such a regions where OCPs never have been used such as the Arctic, Antarctica and others (Muir et al, 1995;Klánová et al, 2008;Wang et al, 2008). The organochlorine pesticides are in general very hydrophobic substances with low aqueous solubility and high octanol-water partition coefficients ranging from 3 to 7 (Wania, Mackay, 1995;Paasivirta et al, 1999).…”

Surface sediment samples from three water reservoirs of Slovakia were analyzed for selected organochlorine pesticides (OCPs). Concentrations of total dichlorodiphenyltrichloroethanes (ΣDDTs) in the sediments from Velke Kozmalovce, Ruzin, and Zemplinska Sirava ranged from 12 to 24 ng g -1 , 5 to 28 ng g -1 , and 1 to 20 ng g -1 , respectively, with the exception of one sediment sample from Zemplinska Sirava, having anomalously high concentration of ΣDDTs (526 ng g -1 ). Concentrations of hexachlorobenzene (HCB) in the sediments from these water reservoirs were generally lower and ranged from 0.3 to 9 ng g -1 . Other organochlorine pesticides such as mirex, lindane and heptachlor were not detected in the surface sediments. Ratios of DDT/(DDE + DDD) were lower than 1.0 in majority of the sediment samples indicating that the degradation of the parent DDT occurred significantly and DDT in the sediments from the studied water reservoirs was derived mainly from the weathered agricultural soils. Moreover, ratios of DDD/DDE indicated that the parent DDT was degraded under aerobic conditions before depositing into the sediments of these water reservoirs. . Iné v sedimentoch sledované organochlórované pesticídy ako mirex, lindán a heptachlór neboli zistené. Vo väčšine vzoriek sedimentov boli hodnoty pomeru DDT/(DDE + DDD) nižšie ako 1, z čoho sa dá usúdiť, že väčšia časť pôvodne prítomného DDT sa rozložila na jeho hlavné metabolity a že DDT v sedimentoch vodných nádrží pochádza najmä z erodovaných poľnohospodárskych pôd. Hodnoty pomeru DDD/DDE ukázali, že predtým ako bol DDT deponovaný do sedimentov vodných nádrží, rozkladal sa najmä za aeróbnych podmienok.KĽÚČOVÉ SLOVÁ: organochlórované pesticídy, DDT, dnové sedimenty, vodná nádrž, organická hmota.

“…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. This was similar to the value in the Yangtze Delta (8.2 ng/g dw) (Liu et al, 2008), lower than the values in Liaodong Bay (42.8 ng/g dw) (Lu et al, 2008), Dalian Bay (21.75 ng/g dw) (Li and Fu, 1998) and the Tianjin Dagu Drainage Canal (87.74 ng/g dw) (Yang et al, 2005), while higher than those in the Pearl River Estuary, China (2.84 ng/g dw) (Hong et al, 1999), Wu-Shi River estuary, Taiwan (2.51 ng/g dw) (Doong et al, 2002a), Ulsan Bay, Korea (2.34 ng/g dw) (Khim et al, 2001), Andes Lake (Borghini et al, 2005) and James Stuart Island in Antarctica (Klanova et al, 2008) (Table 5). Furthermore, according to National Marine Sediment Quality Standards of China (GB18668-2002), all of the sediment samples were unpolluted by ∑HCHs (b500 ng/g dw), and 91.6% of the sediment samples were unpolluted by ∑DDTs (b20 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.
