“…β-HCH (the most toxicological active HCH isomer) was the predominant isomer in HCHs for all mussel samples, similar to the results obtained by several researchers (e.g. Zhou et al 2008). γ-HCH concentrations measured in the mussels (0.03-0.09 ng g −1 ww) were below the recommended levels for human consumption by US EPA (2000) (3.78 ng g −1 ww).…”

“…However, in general, the residuals of total HCHs and DDTs as well as other OCPs in this study are relatively lower than those measured in bivalve mollusks from many sites in other Asian countries (Sarkar et al 2008;Zhou et al 2008), except Korea (Khim et al 2000) and Thailand (Siriwong et al 1991). DDT results obtained in this study are also lower than those obtained for Mytilus sp.…”

This study was conducted to determine the status and trends of organochlorine pesticide (OCP) compounds in the sediment and mussel samples collected along the Istanbul Strait and from the coasts of an island in the Marmara Sea. The total concentrations of OCPs were found in the range of 40-13,852 pg g(-1) dry weight for sediments and 5,195-12,322 pg g(-1) wet weight for mussels. The levels of OCPs in both sediments and mussels were dominated by DDTs and HCHs; β-HCH, 4,4(')-DDD and 4,4(')-DDE were the major pollutants. The degree of sediment pesticide contamination was more severe in the inner part of the strait. OCP concentrations in sediments and mussels were compared with the sediment guideline values and legal limits for human health, respectively. The results showed that OC pesticide contamination in the strait might not pose a serious threat to the health of the marine inhabitants at most of the stations.

“…EDI values obtained in this study were lower than reported in the literature. Zhou et al (2008) reported that estimated daily intake (EDI) of HCH isomers through shellfish by human was 5.83 ng · kg -1 body wt/day. It was ten times higher than EDI obtained in our study.…”

Tomza-Marciniak A., Witczak A. 2010. Distribution of endocrine-disrupting pesticides in water and fish from the Oder River, Poland. Acta Ichthyol. Piscat. 40 (1): 1-9.Background. Organochlorine pesticides (OCPs), which act in a similar way to natural hormones, lead to disorders of the endocrine system in animals and humans (endocrine disruptors). Among food products, fish are considered to be the main source of these compounds in the human diet, posing a health risk to consumers. The aim of this study was to determine concentrations in fish and their environment of certain organochlorine pesticides in fish and their environment and to estimate daily intakes (EDI) of individual pesticides from the fish examined. Materials and Methods. Analyses aimed at detecting the pesticides (OCPs: α-, β-, γ-HCH, heptachlor, heptachlor epoxide, aldrin, dieldrin, and endrin) included samples of water taken from the lower stretch of the Oder River and three fish species, which are commonly harvested in that area. Quantitative analyses were carried out using the Capillary Gas Chromatography/Mass Spectrometry method in a GC MSD HP 6890/5973 apparatus.Results. The study found that concentrations of OCPs in fish gonads were significantly higher than in the muscle tissue. The dominant pesticide compound in gonads of roach and bream was γ-HCH, whilst β-HCH predominated in the muscle tissues of those fishes. Endrin, on the other hand was the major pesticide in the muscle tissue of ide. Mean concentrations of OCPs in the gonads ranged from 0.385 to 0.544 ng · g -1 wet weight (w.w.) for α-HCH, 0.745 to 0.832 ng · g -1 w.w. for γ-HCH, 0.479 to 0.576 ng · g -1 w.w. for dieldrin, and 0.381 to 0.684 ng · g -1 w.w. for endrin. Concentrations of the studied compounds in the water taken from the Oder River followed the order: endrin > γ-HCH > α-HCH > dieldrin > β-HCH > heptachlor ≈ aldrin > heptachlor epoxide. The highest log BCF was obtained for fish gonads and ranged from 1.5 (endrin) to 3.4 (heptachlor epoxide). Estimated daily intakes (EDI) varied from 0.0014% to 0.097% of the acceptable daily intake (ADI). Conclusion. This study revealed no direct risk linked to the consumption of fish captured from the study area. However, from the ecological aspect, the accumulation of organochlorine residues in fish gonads has been considered a dangerous phenomenon, as this may result in decreased reproduction of fish and other aquatic organisms, potentially leading to their extinction.

“…These compounds can enter aquatic environments through effluent release, atmospheric deposition, runoff, etc., and can be transferred into food chains and, finally, accumulated in aquatic organisms (Zhou et al 2008). As is well known, DDT was listed by the Stockholm Convention as 1 of 12 persistent organic pollutants (POPs) in 2004 (Zhu et al 2005), and more recently, a-HCH, b-HCH, and c-HCH (lindane) were added to the list in 2009.…”

“…Technical HCH and DDT were widely used in China from the 1950s until their production was officially banned in 1983 (Gong et al 2007), however, measurable concentrations of HCH and DDT still exist in environmental media in China (Liu et al 2007;Wang et al 2007a;He et al 2008;Zhou et al 2008;Hu et al 2009). From a developing-country perspective, the lack of data and information about the sources, releases, and environmental levels of persistent organic pollutants (POPs) hampers effective assessment and risk evaluation of specific compounds and indicates a great need for research (Bouwman 2004).…”

Residues of organochlorine pesticides (OCPs), hexachlorocyclohexanes (HCHs), and dichlorodiphenyltrichloroethanes (DDTs) and their environmental risks in surface sediments collected from marine and adjacent riverine/estuarine areas in the northern Bohai Sea, China, were investigated. Concentrations of RHCH and RDDT in sediments ranged from below detection (\LOD) to 1964.97 ng g -1 dry wt (dw; mean, 92.51 ng g -1 dw) and \LOD to 86.46 ng g -1 dw (mean, 9.23 ng g -1 dw), respectively. Concentrations of HCH and DDT were generally higher in marine than riverine sediments. Concentrations of HCH and DDT residues found in the present study were higher than those reported in marine and river/ estuary sediments from other areas of the world. The source of HCH in sediments could be explained by the large amount of historical use, while DDT seemed to be a combination of erosion of the weathered soils and longrange atmospheric transport. Concentrations of HCH in sediments from the study areas did not exceed sediment quality guidelines (SQGs), with the exception of c-HCH. However, risks posed by concentrations of DDT observed in sediments were found to be moderate to high compared with those posed by consensus-based SQGs. Although the mean sedimentary concentrations of HCH and DDT found in the area of the northern Bohai Sea, China were lower than suggested SQGs in general, their concentrations in some locations were close to or above the SQGs for adverse effects in benthic organisms and, thus, remain a cause for concern.
