Abstract:

This study was conducted to assess the concentration levels of nine pesticides in vegetables of the Fabaceae family. For this purpose we used chromatography with electron capture detector (GC-ECD) after the extraction and cleaning. The recoveries are between 96 and 99%. The repeatability of the method, expressed by coefficient of variation is less than 4.7%. The limits of quantification of the method are between 0.2 to 0.3 ppb. Residues of these pesticides are distributed differently in vegetables, depending on the organ of the plant and areas where vegetables were grown. For all the vegetables studied, DDD, DDE and DDT were below the limit of quantification. All concentrations of organochlorine pesticides from the samples studied are located within the limits imposed by the regulations of the European Commission.

Keywords:
