ANALYSIS OF FENPROPATHRIN, LAMBDA-CYHALOTHRIN, AND CHLOROTHALONIL IN POTATO AND TOMATO SAMPLES USING GAS CHROMATOGRAPHY WITH AN ELECTRON CAPTURE DETECTOR
Keywords:Gas chromatography, Electron capture detector, Organic vegetable, Non-organic vegetable, Fenpropathrin, Lambda-cyhalothrin, chlorothalonil, Dutch mini-Luke
Objective: This study aimed to analyze pesticide contents in potato and tomato samples.
Methods: In the present study, we determined the presence of the pesticides fenpropathrin, lambda-cyhalothrin, and chlorothalonil in conventional
and organic potatoes and tomatoes using a gas chromatograph equipped with an electron capture detector and validated the associated methods.
Acetone-based extraction was performed using the Dutch mini-Luke method with minimal weights and volumes.
Results: Validation tests showed a range of 70â€“120% and precision of â‰¤20%, and linearity tests on the three standard pesticides gave r values of
â‰¥0.9990 for all three pesticides. Limit of detection and limit of quantitation values showed high sensitivity, although in vegetable sample analyses,
none of the three pesticides were detected.
Conclusion: Our data show that the chosen method for analysis of the pesticides fenpropathrin, lambda-cyhalothrin, and chlorothalonil in potatoes
and tomatoes is valid and that the marketed potatoes and tomatoes meet the SNI 7313: 2008 standard for Maximum Limits of Pesticide Residues on
Agricultural Productsâ€ and the associated Japanese standards
