DEVELOPMENT OF ANALYTICAL METHOD FOR DETERMINATION OF DITHIOCARBAMATE RESIDUES, EXPRESSED AS CS2 IN FRUITS AND VEGETABLES BY GC-ECD

Abstract

This report presents the development of analytical method for determination of dithiocarbamat fungicides (DTCs) residues in vegetables through CS₂ using gas chromatography with electron capture detector (GC-ECD). Research results show that the method recovery ranges from 84.9 – 98.7% and meets the requirement for pesticide residues analyzing. This method has also been applied for analyzing 12 vegetable samples collected in Tan Dinh and Thi Nghe markets. The results showed that the majority of DTCs levels of these samples are lower LOD value except sample BC2 (0.08 mg/g) and sample X3 (0.11 mg/g).
