“…Pesticides applied immediately before a heavy rain may wash into streams or other surface waters and threaten fish and wildlife. For these reasons, usage of pesticides directly around a drinking water source would be forbidden (Bonner 1993;Pesando et al 2004).…”

The levels of 16 organochlorine pesticides (OCPs) in surface water in Mid-Black Sea Region in Turkey were investigated to evaluate their potential pollution and risks. The analysis of OCPs extracted by C-18 solid phase extract was performed using Fisions Mega II Series gas chromatograph coupled by electron capture detector. Surface water samples have been collected seasonally from ten rivers for a period of 1 year. The most commonly encountered OCPs in surface water were the isomers of hexachlorocyclohexane, dieldrin, p,p-DDD, and heptachlor epoxide. In some cases the concentrations detected were higher than the qualitative target levels set by the European Union, especially for δ-hexachlorocyclohexane. The concentration levels found are lower than the EU maximum acceptable concentration of 0.10 μg/l for all compounds examined, except for δ-HCH in two samples (0.2505 μg l −1 in the S-5 and 0.2046 μg l −1 in the S-10). The occurrence of these compounds

“…It will disappear from the water by secondary mechanisms such as adsorption on sediment, biological breakdown by microflora and fauna, and adsorption by fish through gills, skin, and food (Lawson et al, 2011). Although no clinical signs have been observed in aquatic organisms subjected to lindane toxicity, lindane toxicity affects the endocrine system of fish as a result of biochemical changes, resulting in hormonal imbalance due to the breakdown of steroidogenesis in the ovary, and a significant decrease in egg production (Singh et al, 1993;Ensenbach and Nagel, 1997;Pesando et al, 2004;Consiglio et al, 2009;Lawson et al, 2011;Mnif et al, 2011).…”

In this study, histopathological changes induced by lindane a gamma isomer of hexachlorocyclohexane and its intoxication associated with reproductive system and hormone levels were investigated in zebrafish. In all, 320 zebrafish adults approximately 1 year in age, (Danio rerio) obtained from a commercial entity were used in the study. Zebrafish were divided into 8 groups, each one containing 40 zebrafish. Groups were organized as 0 (the control group), 1 ml/L methanol, and 5, 10, 20, 40, 80, 160 µg/L/day lindane. In the study, the gamma-HCH-isomer was applied at rates of 5/10/20/40/80/160 µg/L/day as doses of immersion to each group for 21 days. Macroscopically, the drop in egg production was observed, especially in the 80 and 160 µg/L/day groups of female zebrafish. A microscopic decrease in ovulation and biochemical decreases in estradiol (E 2 ) levels (40/80/160 µg/L) were also observed in the female zebrafish. As a result, lindane was found to cause changes in the reproductive system, and consequently, to cause hormonal disorders and to have significant effects on ovulation and fertilization in the female zebrafish.
