Laboratory Studies

A wide range of mechanisms and processes influence the transformation, movement and availability of pesticides in soil, water and air. This session will provide an update of research and new work including microbial, hydrolytic and photolytic mechanisms; diffusion, plant uptake, adsorption, desorption (including time dependency), bound residues, leaching and volatilization processes. Work on soil microbial understanding, including effects would be welcome, as would modelling work related to laboratory scale investigations. Combined mechanism studies such as aerobic mineralisation, water/sediment and microcosm systems, the effects of light etc. would also be relevant, as would studies on metabolites.

Papers/Posters with new results, new study types, new pesticide molecules, new modelling approaches or a more in-depth understanding would be welcomed, particularly if they contribute to providing more basic scientific information behind calculations of exposure in the soil, water and air compartments.
