Title: A screening method for organochlorine and -phosphorus pesticide residues in vegetables using thin-layer chromatography
Abstract: Abstract A screening method is described for the semi-quantitative determination of the contamination level of organochlorine and -phosphorus pesticides in fruit and vegetables using thin-layer chromatography. The separations and R F values are reproducible using this method that is sensitive and useful in confirmation of identity of the most wisely used and typical pesticides; common organochlorine and organophosphorus pesticides are selectively eluted from extracts without a preliminary purification procedure and detected. The method allows one to determine whether a vegetable is contaminated below the tolerance limits, detecting residues as low as 0.05 p.p.m. of organochlorine and p.p.b. of organophosphorus pesticides.
