Dissipation pattern, risk assessment and decontamination of residues of emamectin benzoate, fipronil and acetamiprid on bell pepper.

Present investigation evaluated the persistence of emamectin benzoate, fipronil, and acetamiprid in bell pepper fruits and soil, their dietary risks, and the effectiveness of decontamination methods. Initial residues at the X dose were 0.045, 1.216, and 0.093 mg kg-1, and at 1.25X dose, 0.088, 1.480, and 0.127 mg kg-1, respectively. Residues fell below the limit of quantification (BLOQ) by the 7th, 21st, and 15th days at the X dose and the 10th, 25th, and 15th days at 1.25X. Half-lives ranged from 2.08-4.17 days. Initial residues in bell pepper soil were 0.028, 0.436, and 0.049 mg/kg at X dose, and 0.055, 0.621, and 0.070 mg/kg at 1.25X dose. By day 10, all residues were BLOQ, except for fipronil at 1.25X dose. Hazard quotients were below 1, indicating no significant dietary risk. Calyx removal was the most effective decontamination method (59.68%), while running water was the least effective (25.22%).
