In Japan, maximum residue limits for pesticides (MRL) in coffee are set on green coffee beans, but not roasted coffee beans, although roasted beans are actually used to prepare coffee for drinking. Little is known about the behavior of pesticides during the roasting process. In the present study, we examined the changes in the concentration of pesticide (organochlorine: γ-BHC, chlordane and hep...
Glutathione S-transferases (GSTs) are one of the major families of detoxifying enzymes that detoxifies different chemical compounds including insecticides in different insect species. Among the GST subclasses, sigma GSTs are found to be the most abundant and conserved among different insect orders. These GSTs are found to play an important role in lipid peroxidation as well as detoxification. C...
American Healthy Homes Survey: a national study of residential pesticides measured from floor wipes.
The U.S. Department of Housing and Urban Development in collaboration with the United States Environmental Protection Agency conducted a survey measuring lead, allergens, and insecticides in a randomly selected nationally representative sample of residential homes. Multistage sampling with clustering was used to select the 1131 homes of which a subset of 500 randomly selected homes included the...
Deltamethrin and piperonyl butoxide two synthetic pyrethroids, when used in a combination it produces synergistic effect. This insecticide has found to be widely the management of mosquito, housefly other insects control various vector born diseases. In this review we assessed toxic effect deltamethrin on beneficial organisms commonly available ecosystem. It was fish, honey bees prime pollinato...
an investigation was carried out on permethrin-susceptible and resistant strain of malaria vector, an.stephensi. efficacy of several pyrethroids such as permetrhrin, deltamethrin, lambdacyhalothrin, cypermethrin and cyfluthrin against this species showed that those with an α-cyano group and dibromo substitutions were more toxic to sensitive strains than the other classes like permethrin. the ra...
Fe(1+x)Te(0.5)Se(0.5) is the archetypical iron-based superconductor. Here we show that the superconducting state is controlled by the stacking of its anti-PbO layers, such that homogeneous ordering hinders superconductivity and the highest volume fractions are observed in phase separated structures as evidenced by either a distribution of lattice parameters or microstrain.
