Analysis of residues of seven pesticides in some fruits and vegetables by means of high pressure liquid chromatography.
The results presented show that a simple one-column HPLC technique can be used in the analysis for residues of seven pesticides in various fruits and vegetables. The pesticides investigated are some of the most important in fruit and vegetable production, including azinphos-methyl and -ethyl, carbaryl, fenitrothion, parathion-methyl and -ethyl and the last also as the oxygen analogue paraxon. Two concentration levels were used in the enrichment of the products, one at half and another at the total permissible concentration value for each pesticide as enforced in Denmark. Multiple additions at each level showed that the recoveries were within 75%-90% and the coefficients of variation were below 10%. The chromatographic development was for 15 min, and since the pre-analysis cleanup is simple, this method is well suited for routine control analysis, in which the time and simplicity of the analysis are of great importance.
