Abstract

Release of chemical substances significantly impacts European waters. Impacts are both direct and indirect, through degradation products, acute and/or chronic toxicity, and/or long-term effects via bioaccumulation in aquatic food chains. As the number of substances is large and measures to reduce emission are costly and time demanding, there is a necessary prioritisation of the efforts through risk assessment studies requiring exposure data, which are both scarce and difficult to obtain. This is complicated by the fact that contaminants may reach the aquatic environment and hence biota and sediments, through several routes ranging from atmospheric deposition (airshed), diffuse and/or point sources in the watershed. Furthermore, a contaminant may arrive constantly during the year or in a pulse due to an accidental release or periodically driven by environmental fluctuations.
