Persistence, Dietary and Ecological Risk Assessment of Chlorantraniliprole in Brinjal Ecosystem

Abstract

Chlorantraniliprole residues in brinjal fruits and soil were determined using GC-MS. The average recoveries of chlorantraniliprole were in the range of 92.7–98.5% with a relative standard deviation of 1.1–3.3% and the matrix effect was less than 2%. The dissipation of chlorantraniliprole residues followed first-order kinetics with a half-life of 2.09 and 1.75 days for fruits and soil, respectively. Consumer dietary risk assessment indicated that risk quotient was less than one even on day the application of chlorantraniliprole and does not pose a risk to the health of consumer. The calculated environmental risk quotient (RQ) values were found to be less than one, indicating the low risk to earthworms and arthropods following the application chlorantraniliprole in the brinjal field.
