Journal of chromatography. A, 1129(2), 300-303 (2006-09-06)
A multi-pesticide (MP) method was developed and single-laboratory validated for the quality control of commercial pesticide products containing alachlor, chlorpyrifos methyl, fenthion and trifluralin as active ingredients (a.i.). A capillary gas chromatographic system with flame ionization detection (FID) and a
Analytical and bioanalytical chemistry, 390(7), 1933-1941 (2008-02-27)
The present work describes a headspace single-drop microextraction (HS-SDME) method in conjunction with gas chromatography electron capture detection (GC-ECD) for the determination of an organophosphate insecticide, chlorpyrifos-ethyl (CPF), in rat liver. Sample preparation included tissue homogenization with methanol in the
Medical and veterinary entomology, 23(4), 317-325 (2009-11-28)
Three insecticides - the pyrethroid deltamethrin, the carbamate carbosulfan and the organophosphate chlorpyrifos-methyl - were tested on mosquito nets in experimental huts to determine their potential for introduction as malaria control measures. Their behavioural effects and efficacy were examined in
A rapid (less than 10 min), qualitative and semi-quantitative immunochromatography using colloidal gold-antibody probe was successfully developed and applied in determination of chlorpyrifos-methyl (a wide-spectrum organophosphorus pesticide) in water samples. The qualitative detection limit of chlorpyrifos-methyl was determined as 0.6
Journal of environmental science and health. Part. B, Pesticides, food contaminants, and agricultural wastes, 44(3), 235-240 (2009-03-13)
In the present work changes in the adsorption of the pesticide chlorpyrifos-methyl (CLP-m) on soil colloids induced by application of surfactants were determined using a batch equilibrium method. The surfactants used were sodium dodecyl sulphate (SDS), Tween 20, and dihexadecyldimethylammonium
