Dietary Risk Assessment and Decontamination of Chlorantraniliprole Residues in Tomato through Different Household Approaches

The residues of chlorantraniliprole applied at the dose of 30 g ai ha^-1 in tomato crop were estimated at different time intervals. Samples collected at 0 and 1 day afterthe third application were analyzed using high-performance liquid chromatography (HPLC) with a photo-diode array (PDA) detector with a wavelength of 260 nm. The limit of quantification (LOQ) was 0.05 mg kg^-1. The study aimed to assess residual levels on harvested tomatoes at 0 and 1 day. Initial deposits were found to be 0.70 mg kg^-1 at 0 day and 0.21 mg kg^-1 at 1 day, showing a reduction ranging from 12.9 to 54.3% and 4.7 to 52.4%, respectively. The highest reduction of residues due to processing was observed while boiling and least at dipping in 4% acetic acid solution. Further, dietary risk assessment confirmed no risk to Indian consumers, as the risk quotient remained below one.
