Description of Thesis

Thesis description: Following release to aquatic systems, many environmental contaminants will associate with the sediment compartment and consequently may affect benthic organisms. One important factor in determining potential impacts is the bioavailability of the contaminants. While we have a fairly good understanding of the factors and processes that influence the fate and uptake of neutral organic chemicals in the aquatic environment, less is known about ionisable chemicals, especially in sediments. This project aims to explore the factors and processes affecting uptake of ionisable chemicals from sediment into benthic invertebrates. The output of the studies is likely to be an improved modelling approach for use to better assess the environmental risks of ionisable substances.
