Project objectives:
Processes underlying sorption, ageing and bioavailability are the key soil parameters controlling dispersion of pollution to ground water and exposure 
of fauna and plants within in the soil environment. It is therefore the overall aim of this project to improve ground water protection and assessment of ecological
risk of contaminated land and connective freshwater by developing and validating a novel decision support system for sustainable management of contaminated
land that includes measures of bioavailability. We will study the underlying mechanisms affecting the bioavailability and mobility of contaminants in soils
and identify key parameters controlling sorption, desorption, mobility, leaching and ecotoxicity in soil and aquatic receptors. We will assess changes
in the bioavailable fraction of model compounds in different soil types using various biological assessment tools and chemical extraction methods. We will
measure and monitor changes in the bioavailable fraction during ageing processes. The usefulness and ecological relevance of these measures of bioavailability
will be evaluated by correlating them to ecotoxicological studies with soil and water organisms and with changes in ecosystem structure observed at field
sites with mixed pollution, and by collecting ground water samples.
Project Summary:
The primary objective is to improve ground water: protection and ecological risk assessment by developing and validating a decision support system (DSS) 
for sustainable management of contaminated land and connective freshwater and groundwater systems. Current risk assessment practise is based on determining
total concentrations in soils, which overestimate risks by not considering bioavailability. Bioavailability provides a measure of exposure to organisms
within in the soil and influence dispersion of pollutants to ground water . The results from this project will help in reducing remediation costs and at the same
time ensure sustainable land management, as it links bioavailability measures to ecological effects and ground water pollution. The DSS will help site redevelopers
to manage risk by providing rapid, cheap and reliable chemical and biological tools for assessing bioavailability and leaching.
