Multiresidue determination of organophosphorus pesticides in corn oil using solid-phase extraction with lanthanum silicate sorbent and gas chromatography
Phosalone, malathion and diazinon were analyzed in corn oil using solid phase extraction (SPE)with lanthanum silicate as a new solid sorbent followed by gas chromatography with nitrogenphosphorus detection (GC-NPD). The efficiency of different eluents (methanol, dichloromethane,ethyl acetate, dichloromethane — ethyl acetate (1:1) and ethyl acetate — methanol (1:1)) werecompared for elution of o...
متن کاملDetermination of organophosphorus pesticides in stomach contents of postmortem animals by QuEChERS and gas chromatography.
The quick, easy, cheap, effective, rugged and safe (QuEChERS) method for sample preparation was applied to determine seven organophosphorus pesticides (OPs) in stomach contents of poisoned postmortem animals. The pesticides consisted of diazinon, edifenphos, ethyl p-nitrophenyl phenylphosphonothioate, fenitrothion, monocrotophos, parathion and phosphamindon, and tested samples included stomach ...
متن کاملDetermination of Twenty Organophosphorus Pesticides in Wheat Samples from Different Regions of Iran
Background: Organophosphorus pesticides are widely used in agriculture, homes, gardens, and veterinary practices. Extensive application of pesticides in agriculture often results in residues of these compounds being absorbed into the foods, including wheat. The aim of this study was to evaluate the residue levels of 20 organophosphorus pesticides in wheat samples collected from different region...
متن کاملGas-liquid chromatographic determination
A method for the determination of total bile acids in human feces that is suitable for routine application is described and discussed. Bile acids are extracted from freezedried feces with acetic acid and toluene, in the presence of the i?ternal standard 23-nordeoxycholic acid. After saponification of the extract, bile acids and the internal standard are methylated and converted by mild chromic ...
متن کاملMultiresidue method for the gas chromatographic determination of pesticides in honey after solid-phase extraction cleanup.
A new multiresidue method is described for the determination of pesticides in honey. The method involves dissolution of the honey in a methanol-water mixture, followed by solid-phase extraction cleanup and gas chromatographic determination. Twenty-six pesticides used on flowering field crops, on flowering fruit and vegetables, or as acaricides to control Varroa jacobsoni in beehives are determi...
