Agrochemical fate and transport

Man-made agrochemicals are investigated in a wide-range of environments, such as orchards, irrigation canals, post harvest commodity treatment facilities, and organisms.  Examples of these chemicals we routinely analyze include: fumigants, pesticides, fungicides, disinfection byproducts, engineered nanomaterials, and endocrine disruptors.  Considerable effort is spent delineating the spatio-temporal effects of concentration-dependent phenomenon, at both the molecular and systemic levels, on the formation, degradation, transport, and toxicity (targeted and nontargeted) of these chemicals.
