Determination of tetraconazole and diniconazole fungicide residues in tomatoes and green beans by capillary gas chromatography.
A sensitive gas chromatographic method using an electron-capture detector (ECD) has been developed for the determination of tetraconazole and diniconazole fungicide residues in tomatoes and green beans. The developed method consists of extraction with methanol, partition with methylene chloride, and column chromatographic clean-up, followed by capillary gas chromatographic determination. The re...
متن کاملPesticide 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 pesticide residues in nonfatty foods by supercritical fluid extraction and gas chromatography/mass spectrometry: collaborative study.
A collaborative study was conducted to determine multiple pesticide residues in apple, green bean, and carrot by using supercritical fluid extraction (SFE) and gas chromatography/mass spectrometry (GC/MS). Seventeen laboratories from 7 countries participated in the final study, and a variety of different instruments was used by collaborators. The procedure simply entails 3 steps: (1) mix 1.1 g ...
متن کاملDetermination of Organophosphorus Pesticide Residues in the Liver by Gas Chromatography with Flame Photometric Detection
A method for simultaneous determination of residues of six organophosphorus pesticides in animal liver samples has been developed and validated. The method is based on the extraction of organophosphorus pesticides with a mixture of acetone-petroleum ether, clean up on a gel permeation chromatography, further clean up on a small silica gel column, and finally determination by gas chromatography ...
