Endosulfan is a pesticide of organochlorine group. The lipophilic nature of endosulfan suggests that endosulfan initially accumulates in fatty tissues and that relatively high amounts can be found in the liver and kidneys after exposure. In the present investigation spermatozoa architecture after endosulfan treatment in mice have been evaluated. Hence, the dose of 3 mg/Kg b.w of Endosulfan was ...

Endosulfan has emerged as a major environmental menace worldwide due to  extensive usage and environmental persistence, seeking its remedial by a cheaper and efficient means. Therefore, natural resource (soil) was explored to search a potential candidate for biodegradation of endosulfan. A soil bacterium was enriched and isolated by applying a strong nutritional selection pressure, using a non-...

The objective of this study was to find and validate estrogen-related biomarkers from plasma proteins in Oryzias latipes after exposure to an estrogen disrupting compound, α-endosulfan. The acute toxicity of α-endosulfan on O. latipes after 96 h of exposure was 13.72, 16.18, and 22.18 μg L(-1) for the LC10, LC20, and LC50 values, respectively. To confirm estrogenic disturbance by α-endosulfan, ...

Organochlorine pesticides (OCPs), viz. β-hexachlorocyclohexane (β-HCH), γ-HCH, aldrin, dieldrin, endrin, heptachlor, endosulfan-I, endosulfan-II, heptachlor endoepoxide, heptachlor exoepoxide, mirex, dicofol, o,p'-dichlorodiphenyltrichloroethane (o,p'-DDT), p,p'-dichlorodiphenyltrichloroethane (p,p'-DDT), dichlorodiphenyldichloroethane (DDD), and dichlorodiphenyltrichloroethylene (DDE) and 12 o...

The effects of two different categories of pesticides viz. chlorpyrifos (an organophosphate) and endosulfan (an organochlorine cyclodiene) were evaluated on soil dehydrogenase activity. The medium and higher dose of endosulfan resulted in the significant decrease in dehydrogenase activity till third and fourth week of treatment, respectively. In case of chlorpyrifos, decrease in dehydrogenase a...

Present study revealed the importance of endosulfan in mediating stress responses in Sorghum bicolor L. Moench (variety JP-1-1). The seeds treated with different concentrations (0.2, 0.4 and 0.6%) of endosulfan showed a significant decrease in percent germination over control. As the concentration increased, the shoot length, root length and biomass decreased. The amount of chlorophyll-a and pr...

Field tests were conducted to evaluate the effect of Spodoptera litura (Fab.) nuclear polyhedrosis virus (NPVS) alone and in combination with endosulfan and neemarin (neem seed kernel extract) against S. litura in cabbage. Treatment with NPV-S (500 LE/ha) + Endosulfan (625 ml/ha) was better in reducing the larval population and increasing yield than other treatments. However, considering cost b...

Endosulfanis metabolized to a single metabolite, endosulfan sulfate, in pooled human liver microsomes (Km 9.8 M, Vmax 178.5 pmol/mg/min). With the use of recombinant cytochrome P450 (P450) isoforms, we identified CYP2B6 (Km 16.2 M, Vmax 11.4 nmol/nmol P450/min) and CYP3A4 (Km 14.4 M, Vmax 1.3 nmol/nmol P450/min) as the primary enzymes catalyzing the metabolism of endosulfan, although CYP2B6 had...

Abstract—In the present study, presence of endosulfan, imidacloprid, carbendazim, in the soil /vegetables/cereals and water samples was observed in agriculture fields of Uttarakhand. In view of biodegradation of these pesticides, 9 bacterial isolates were recovered from the soil samples of the fields which tolerated endosulfan, imidacloprid, carbendazim from 100 to 200 μg/ml. Three bacterial co...

*Corresponding author, Email: [email protected] Tel./Fax: +91-9884787202 ABSTRACT: Endosulfan, a chlorinated cyclodiene insecticide is of environmental concern because of its apparent persistence and toxicity to many non target organisms. Endosulfan is hydrophobic and persists in soil for more than a year. To overcome the problem of hydrophobic and limited availability, surfactants play a major...
