A convenient fluorescence quenching method for determination of Quizalofop-p-ethyl(Qpe) was proposed in this paper. Eosin Y(EY) is a red dye with strong green fluorescence (λex/λem=519/540nm). The interaction between EY, Pd(II) and Qpe was investigated by fluorescence spectroscopy, resonance Rayleigh scattering(RRS)

Organophosphates (e.g. chlorpyrifos ethyl) and carbamates (e.g. fenobucarb) are commonly used to control a wide range of pests in rice fields of the Mekong Delta in Vietnam. This study assesses the combined effect of chlorpyrifos ethyl (CPF) and fenobucarb (F)
Mice showed no toxic signs after a single injection of o-sec-butylphenyl methylcarbamate (BPMC, 10 mg/kg) or 2-isopropoxyphenyl-N-methylcarbamate (propoxur, 2 mg/kg). Each dose of BPMC or propoxur caused an increase in acetylcholine content and a decrease in acetylcholinesterase activity in the

Organophosphate (OP) insecticides have been used widely to control Culex pipiens L. populations and this has led to the emergence of OP-resistance. Predominantly, resistance in Cx. pipiens is caused by over-production of nonspecific esterases, such as Est beta 1(1) and

This study was undertaken to determine whether interactions of toxicologic importance might occur during combined exposure of male mice to 2-sec-butylphenyl N-methylcarbamate (BPMC) and O,O-dimethyl O-(3-methyl-4-methylthiophenyl)phosphorothioate (fenthion). The equitoxic coadministration of BPMC and fenthion resulted in only a 1.6-fold potentiation
