Environmental fate:
Animals:Thiobencarb was metabolised principally by S-oxygenation to the corresponding sulfoxide by liver microsomes from the striped bass (J. R. Cashman , Chem. Res. Toxicol., 1990, 3, 433).Soil:Rapidly adsorbed by soil, and not readily leached. Degradation is primarily by microbial breakdown, with little loss from volatilisation and photodegradation. Half-life in soil varies from 2-3 w under aerobic conditions to 6-8 under an
