Endosulfan is an insecticide-acaricide used in South Florida and is one of the remaining organochlorine insecticides registered under the Federal Insecticide Fungicide and Rodenticide Act by the U.S.EPA. The technical grade material consists of two isomers (alpha-, beta-) and the main environmental metabolite in water, sediment and tissue is endosulfan sulfate through oxidation. A comprehensive...

Endosulfan as a new member of persistent organic pollutants has been shown to induce reproductive dysfunction in various animal models. However, the action mechanism of endosulfan-produced reproductive toxicity remains largely unknown. This study was focused on investigating the reproductive toxicity induced by α-endosulfan and clarifying the role of mitochondria and genotoxic response genes in...

toxic effects of malathion and endosulfan to fertile chicken eggs were determined. in-jection of 1.25, 2.5, 5.0 and 10.0 mg/egg of malathion into yolk sac of fertile eggs prior to incubation caused mortality of 10.0, 30.0, 83.33 and 93.33% respectively. similar trend was observed with injection of endosulfan doses. malathion and endosulfan at 1.25 mg/egg caused no pronounced ld50 increase in mo...

This paper assesses the uptake of persistent organic pollutants (POP's) into plants. In particular, uptake of alpha-endosulfan, beta-endosulfan and endosulfan sulfate from lettuce. The lettuce plants were grown on compost that had previously been contaminated at 10 and 50 microg g(-1) per POP. The soil was slurry spiked by adding the appropriate amount of POP in acetone in an approximate ratio ...

Endosulfan contamination is one of the major concerns of soil ecosystem, which causes detrimental effects not only to humans but also to animals and plants. Therefore, the aim of this study was to isolate and identify a novel bacterial strain capable of degrading endosulfan in agriculture contaminated soils. A novel bacterial strain was isolated from the sugarcane field contaminated with endosu...

Omissions and Flawed Data The main objective of the Endosulfan Manufacturers and Formulators Welfare Association in India is disseminating scientific facts concerning the use of endosulfan. Because endosulfan is used in several countries, the association watches for global news and information relevant to endosulfan. Members of the Endosulfan Manufacturers and Formulators Welfare Association ar...

Endosulfan (6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro6,9-methano-2,4,3-benzo-odioxa-thiepin-3-oxide) is a chlorinated cyclodiene insecticide which acts as a contact poison in a wide variety of insects and mites (Naqvi and Vaishnavi, 1993). Endosulfan was first registered for use in the USA in 1954 to control agricultural insects and mite pests. Due to its toxic effect, the World Health O...

The concentrations of 16 pesticides residues (alpha BHC, gamma BHC (lindane), beta BHC, Heptachlor, Aldrin, Heptachlor Epoxide, Endosulfan I, Dieldrin, Endrin, Endosulfan II, 4, 4 DDT, Endosulfan Aldehyde, Endosulfan sulfate, Atrazine, Phosphomethylglycine and Carbofuran) in two fish species (Tilapia zilli and Clarias gariepinus) from selected rivers (Illushi, Owan and Ogbesse) in Edo State, Ni...

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

Endosulfan is an organochlorine pesticide commonly used in agriculture yet classified by the Stockholm Convention in 2011 as a persistent organic pollutant (POP). Its potential toxicity makes its continued use a major public health concern. Despite studies in laboratory animals, the molecular mechanisms underlying the carcinogenic effects of endosulfan in human liver remain poorly understood. I...
