Dissipation of the insecticide profenofos in tropical agricultural soils (Berambadi catchment, South India): insight from compound-specific isotope analysis (CSIA)

Résumé

Rapid dissipation of profenofos in soil, with half-life of 1.1 ± 0.6 days. • Development of carbon CSIA of profenofos with precision of ± 0.3 ‰ for δ 13 C values. • Photolysis and biodegradation in soil of profenofos caused carbon isotope fractionation. • Profenofos biodegradation in soil reached 96 %, 3 days after a field application. • Experimental data aligned with model, showing minimal (< 0.02 %) profenofos leaching.
