Pesticide residues analysis in Iranian fruits and vegetables by Gas Chromatography-Mass Spectrometry
Pesticide residues in fruits and vegetables are one of the highest concerns of consumers who need food safety. In this study, forty-eight pesticide residues from different chemical structure including organochlorine, organophosphorus, organonitrogen, dicarboximides, strobilurin, triazine, pyrethroids and other chemical groups. in 85 fruits and vegetables were determined and confirmed by GC-MS. ...

متن کاملDetermination of organochlorine pesticide residues in rice by gas chromatography tandem mass spectrometry
A simple and sensitive method for the determination of organochlorine pesticide residues namely HCH isomers (alpha, beta, gamma (lindane) & delta), DDT isomers (2,4-DDE, 4,4-DDE, 2,4-DDD, 4,4-DDD, 2,4-DDT & 4,4DDT), endosulfan (alpha and beta), endosulfan sulfate, heptachlor, heptachlor epoxide aldrin, dieldrin, endrin, chlorthalonil, chlordane & dicofol in rice grains by gas chromatography –ta...
متن کاملAnalysis of pesticide residues in fruits, vegetables, and milk by gas chromatography/tandem mass spectrometry.
A method for detection, quantitation, and confirmation of more than 100 pesticides by gas chromatography (GC) with ion trap mass spectrometry (MS/MS) has been developed. The sensitivity of this method for many analytes is equal to or lower than those of selective GC detectors such as flame photometric detectors and electrolytic conductivity detectors. Using MS/MS, very low detection limits and ...
متن کاملValidation of the analysis method of 25 pesticide residues in rice using LC-MS/MS device (liquid chromatography-mass spectrometry)
Introduction: In recent years, due to the increase in the use of pesticides in agricultural products and its entry into the human food chain, there has been an increase in concerns about the health of food among people. Therefore, the purpose of conducting this research is to validate the analysis method. 25 pesticide residues in rice using LC-MS/MS. Methods: In this research, a simultaneous an...
