Organochlorine pesticides such as endosulfan have been shown to have both lethal and sublethal effects on amphibians. In this context, behavioral endpoints have proved their usefulness in evidencing impacts of such chemicals at environmental concentrations that do not necessarily cause mortality. The recent development of video-tracking technologies now offers the possibility of accurately quan...

One of the most common pesticides in the developing world, endosulfan, can be detected in ppm levels using gold nanoparticles. Endosulfan adsorbs on the nanoparticle surface and upon interaction for a long time, the nanoparticles precipitate from the solution. Interaction with silver is weak, yet adsorption occurs leading to removal of endosulfan from the solution. A multilayer assembly of gold...

There is experimental evidence of adverse effects of endosulfan on the male reproductive system, but there are no human data. Therefore, we undertook a study to examine the relationship between environmental endosulfan exposure and reproductive development in male children and adolescents. The study population was composed of 117 male schoolchildren (10-19 years of age) of a village situated at...

A seasonal field campaign by passive sampling was conducted from February 2008 to February 2009, aiming to measure air concentrations of organochlorine pesticides (OCPs) in the urban and suburban areas in Dalian. At the urban site, similar annual average concentrations of α-endosulfan and α-HCH were found, both being approximately 4 times as high as those of p,p'-DDT and p,p'-DDE, while at the ...

Recently use of endosulfan has aroused a great concern among clinical and basic neuroscientists as besides adult population even the children residing in some areas of touristic state of Kerala, India which are under constant spraying of endosulfan had shown symptoms of CNS dysfunctioning including cerebral palsy, retardation of mental and physical growth, epilepsy and various congenital anomal...

This project consisted of two separate studies. The first was conducted with the two isomers of endo14 sulfan and three of its metabolites, the other with C technical endosulfan. The primary objective of the first study was to examine qualitatively and quantitatively differences in toxicant metabolism among rats subjected to low, normal, and high temperatures. Young adult, male rats were dosed ...

Overall persistence (POV) and long-range transport potential (LRTP) of and endosulfan and two of their transformation products, endosulfan sulfate and endosulfan diol, are estimated with two multimedia box models, the OECD POV and LRTP Screening Tool and the global, latitudinally resolved model CliMoChem. The OECD Tool yields POV and LRTP for each compound separately, whereas the CliMoChem mode...

In the present study, changes in velocity of cytoplasmic streaming in the giant internodal cells of Nitella for varying concentration of the pesticides, 2,4-D, dieldrin, malathion, methyl parathion and endosulfan, were measured. Marked decrease in the velocity of cytoplasmic streaming was found at the concentrations of 0.01, 0.1, 1, 10 and 100mM. Dieldrin was the most toxic to all the pesticide...

The problem of endosulfan bioremediation is poor solubility and restriction of appropriate biocatalyst. One promising approach in increasing the bioavailability of this organic compound is addition of surfactants. The synthetic surfactant Tween 80 was non-toxic to soil microorganisms and inert to the soil matrix and had the additional benefit of causing an enhanced dissolution rate for single c...
