“…The liver is the main organ for detoxification (Dutta et al, 1993) that suffers serious morphological alterations in fish exposed to pesticides (Rodrigues and Fanta, 1998). Alterations in the liver may be useful as markers that indicate prior exposure to environmental stressors.…”

“…However, values in a few sites are considerately high considering to being used as a drinking water source. Due to the analytical restrictions, ionic and thermally unstable pesticides could not be covered by our monitoring study, although some of them were also frequently used in the study area and they were also identified as potential or suspected endocrine disruptors such as atrazine, 2,4-D, diazinon, malathion (Dutta et al, 1993;Crain and Guillette, 1998;Ren and Jiang, 2001;Laura and Dutta, 2005). Further monitoring method study, which can screen more endocrinedisrupting pesticides, is also needed to understand and assess fully the contamination status about endocrinedisrupting pesticides in the studied area.…”

For screening 31 potential or suspected endocrine-disrupting pesticides in water and surface sediments, a multiresidue analysis method based on gas chromatography with electron capture detection (GC/ECD) was developed. Solid phase extraction (SPE) technology with Oasis Ò HLB cartridge was also applied in sample extraction. The relevant mean recoveries were 70-103% and 71-103% for water and sediment, respectively. Relative standard deviations (RSD) are 2.0-7.0%, 4.0-8.0% for water and sediment, respectively. Thirty one pesticides (a-HCH, b-HCH, c-HCH, d-HCH, hexachlorobenzene (HCB), aldrin, heptachlor, endosulfan I & II, p,p 0 -DDD, o,p 0 -DDT, p,p 0 -DDT, p,p 0 -DDE, endrin aldehyde, endosulfan sulphate, methoxychlor, hepachlor epoxide, a-chlordane, c-chlordane, dieldrin, endrin, dicofol, acetochlor, alachlor, metolachlor, chlorpyriphos, nitrofen, trifluralin, cypermethrin, fenvalerate, deltamethrin) in water and surface sediment samples from Beijing Guanting reservoir were analyzed. Concentrations of pesticides ranged from 7.59 to 36.0 ng g À1 on a dry wt. basis for sediment samples, from 279.3 to 2740 ng l À1 for pore waters and from 48.8 to 890 ng l À1 for water samples, respectively, with a mean concentration of 10.7 ng g À1 in sediment, 735 ng l À1 in pore water and 295 ng l À1 in water, respectively. The data obtained provides information on the levels and sources of endocrine-disrupting pesticides in Guanting reservoir. These results underscore the need to improved environmental protection measures in order to reduce the exposure of the population and aquatic biota to these endocrine-disrupting compounds.

Abstract. GuanTing Reservoir (GTR) is one of two main water resources for the agriculture, industry, and living uses of Beijing (China). As a result of extensive pollution over the last few decades (particularly the 1980s), the reservoir has not supplied potable water to Beijing city since 1997. Composition, distribution, and characterization of 31 suspected endocrine-disrupting pesticides in surface water, pore water, and surface sediments from the reservoir are reported in this study. An analytical procedure based on solid-phase extraction (SPE) technology and capillary gas chromatography with electroncapture detection has been developed for the simultaneous determination of the 31 suspected endocrine-disrupting pesticides including the compounds hexachlorocyclohexane, cyclodiene, diphenyl aliphatic, chlordane, and other selected pesticides (hexachlorobenzene, heptachlor, endrin aldehyde, hepachlor epoxide, dicofol, acetochlor, alachlor, metolachlor, chlorpyriphos, nitrofen, trifluralin, cypermethrin, fenvalerate, and deltamethrin). The result shows that the pesticide pollution is moderate in GTR and its tributaries, although pesticide residue values in a few sites are quite high when considering their endocrine-disrupting effects and chronic health effects. Among the analyzed pesticides, p,p¢-DDE, o,p¢-DDT, b-HCH, endosulfan sulfate, and aldrin were the most abundant pesticides in water while o,p¢-DOT, d-HCH, b-HCH, p,p¢-DDE, p,p¢-DDT, and endosulfan sulfate were the most abundant in sediment. The variation in concentration of pesticides among sites can be expected to be caused by several factors such as contaminants in the rivers and drainage of contaminated water from the surrounding agricultural fields.
