Supervised field experiments were conducted to study the dissipation of ethion, chlorpyriphos, profenophos, carbendazim and cypermethrin in curry leaves. An analytical method was developed in line with the SANTE guideline on the method validation procedure for pesticide residue analysis. The validated method showed good recovery (70–120%) and repeatability (<20%). The limit of detection and limit of quantification were determined as 0.01 and 0.05 mg/kg respectively, for all analytes, except cypermethrin (0.05 and 0.1 mg/kg respectively). The mean initial deposit of pesticides analysed ranged from 9.53 to 93.92 mg/kg with a half-life of <8 days. Except for ethion, the dietary risk assessment for women, men and children was at an acceptable level.

Abstract


Supervised field experiments were conducted to study the dissipation of ethion, chlorpyriphos, profenophos, carbendazim and cypermethrin in curry leaves. An analytical method was developed in line with the SANTE guideline on the method validation procedure for pesticide residue analysis. The validated method showed good recovery (70–120%) and repeatability (<20%). The limit of detection and limit of quantification were determined as 0.01 and 0.05 mg/kg respectively, for all analytes, except cypermethrin (0.05 and 0.1 mg/kg respectively). The mean initial deposit of pesticides analysed ranged from 9.53 to 93.92 mg/kg with a half-life of <8 days. Except for ethion, the dietary risk assessment for women, men and children was at an acceptable level.
