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 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...

Organochlorine pesticides (HCB, HCH with α-, β-, and γ isomers, heptachlor, cis-heptachlor epoxyde, trans-heptachlor epoxyde, endosulfan with α- and β isomers, sulfate endosulfan, o,p'-DDT, p,p'-DDT, o,p'-DDE, p,p'-DDE, o,p'-DDD, p,p'-DDD, chlorothalonil, alachlor, aldrin, dieldrin, methoxychlor, oxychlordane, chlordane with α- and γ isomers, p,p'-dicofol and o,p'-dicofol) and indicators PCBs (...

*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...

BACKGROUND In South Africa there is little data on environmental pollution of rural water sources by agrochemicals. METHODS This study investigated pesticide contamination of ground and surface water in three intensive agricultural areas in the Western Cape: the Hex River Valley, Grabouw and Piketberg. Monitoring for endosulfan and chlorpyrifos at low levels was conducted as well as screening...

Endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9methano-2,4,3-benzodioxathiepin 3-oxide), a pesticide that is highly toxic to aquatic organisms, is widely used in the cotton (Gossypium hirsutum L.) industry in Australia and is a risk to the downstream riverine environment. We used the GLEAMS model to evaluate the effectiveness of a range of management scenarios aimed at minimizi...

Endosulfan can induce convulsions that could lead to brain damage. The variability and lack of specificity of neurological signs and symptoms in the pre-convulsive stages makes early diagnosis difficult. We sought to determine if electrophysiological exploration of the cerebral cortex could yield objective signs of endosulfan intoxication at levels that do not elicit convulsions. Endosulfan was...
