Her expertise includes both environmental and human health risk assessment, with particular emphasis on metal toxicity to terrestrial and aquatic organisms and humans, contaminant bioaccumulation, and food chain modelling. Lesley is responsible for conducting or overseeing risk assessments for aquatic, terrestrial or human receptors; developing and implementing selenium management and monitoring plans; and effluent discharge permit applications under the BC Environmental Management Act.
