Research currently focused on investigating (1) the metabolic actions of toxic chemicals in aquatic animals using nuclear magnetic resonance (NMR)-based metabolomics (environmental metabolomics); (2) the biochemical actions of toxic chemicals in aquatic animals using in vivo NMR; (3) the kinetics and biotransformation of pesticides and petroleum hydrocarbons in aquatic animals; (4) the influence of surfactants on the bioavailability of petroleum hydrocarbons in aquatic systems; (5) the dissipation of herbicides via volatilization, soil sorption, photodegradation and microbial degradation under rice field conditions; and (6) the fate of pesticides and petroleum hydrocarbons in marine mussels and sediments.
