Outline of Final Research Achievements

Successful environmental risk assessments require a profound understanding of the partitioning and sorption behavior of chemicals in the environment and organisms. This study considered ion exchange resins (IERs) as possible model sorbents to investigate the sorption behavior of ionic organic contaminants. Sorption coefficients of IERs for a large number of ionic chemicals were measured by batch and column experiments and were compared to environmentally and biologically relevant sorption coefficients. The measured IEP sorption coefficients correlate well with environmental and biological sorption coefficients in some cases, suggesting that the former can be used for predictions of the latter.
