ABSTRACT The persistence study of some non-approved pesticides viz., fenvalerate, imidacloprid and profenofos on cabbage heads and cabbage cropped soil was conducted using gas chromatography-mass spectrometry after application of recommended single and double doses. QuEChERS technique was employed for sample preparation methodology and validated, as per SANTE 2019 guidelines. Residue analysis in cabbage cropped soil was also undertaken at the harvesting stage. Samples were extracted with acetonitrile and cleaned up with anhydrous magnesium sulphate and primary secondary amine (PSA). Average recoveries were in the accepted range of 80-120%. Half-life and waiting period were calculated. The efficiency of different household decontaminants in mitigating the residues of from the cabbage heads were evaluated from consumption point of view. Among the different decontaminants unwrapping of the outer leaves from the cabbage head proven to be most efficient treatment as it removes 63-70 per cent of residues. |
