Determination 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 کامل[Multiresidue method for determination of pesticide residues in processed foods by GC/MS/MS].
A rapid and simple multiresidue method has been established for determination of pesticide residues in processed foods by GC/MS/MS. The pesticides were extracted with ethyl acetate, and were cleaned up with a double-layered SPE cartridge column (graphite carbon black/PSA silica gel). Recovery tests of 258 pesticides from five kinds of processed foods (dumpling, curry, French fries, fried chicke...
متن کاملStudies on Analysis of Pesticide Residues in Foods (XXVIII) Determination of 33 Organophosphorus Pesticides in Agricultural Crops
A modified method for the simultaneous determination of 33 organophosphorus pesticides in agricultural crops was presented. After extraction of samples with acetonitrile, the pesticides are transfered into 20% dichloromethane in benzene, cleaned up by charcoal column chromatography, and then determined simultaneously by the gas liquid chromatography with a flame photometric detector using the c...
متن کامل[Investigation of pesticide residues in foods distributed in Kitakyushu City].
We investigated 160 kinds of pesticide residues in 715 samples of 116 kinds of foods distributed in Kitakyushu city. Sixty kinds of pesticides were detected in 55 kinds of foods (204 samples) in the range of 0.002-22 mg/kg. Five kinds of pesticides in 7 samples violated the residue standards and the indication of "unused". The detection ratios of unregulated pesticide in domestic and imported f...
متن کامل[Survey of pesticide residues in baby foods (1999.4-2005.6)].
A survey of pesticide residues in 316 baby foods on the Tokyo market from April 1999 to June 2005 was carried out. Fifteen kinds of pesticides, including organophosphorus, organochlorine, carbamate, pyrethroid and others, were detected between at levels Tr (below 0.01 ppm) and 0.55 ppm from 28 samples. The baby foods in which residual pesticides were detected were produced from flour, leaf vege...
