Abstract:
Dissipation dynamics of profenofos, triazophos, cypermethrin are studied at doses used by farmers for recommending maximum residue limits (MRL) and pre harvest intervals (PHI) for food safety based on chronic hazard exposure assessment. Profenofos @ 500, triazophos @ 500 and cypermethrin @ 50 g ai ha-1 sprayed twice and fruit samples analysed following validated QuEChERS method using GC-ECD, GC-TSD, GC-MS/MS (TQD). Fruit samples are detected with deposits of 1.698 mg kg-1 profenofos, 1.108 mg kg-1 triazophos, and 0.158 mg kg-1 cypermethrin dissipated to BDL by 10th, 7th and 5th day, respectively. MRL of 4 mg kg-1 for profenofos, 3 mg kg-1 for triazophos and 0.4 mg kg-1 for cypermethrin is recommended based on chronic hazard exposure assessment parameters (theoretical maximum daily intake), and PHI of 1 day is recommended for food safety taking into consideration of MRLs of Codex and MRLs calculated from present investigation
