Field-investigations show that species populations in the wild are effected at exposure concentrations far below those predicted by the current risk assessment framework. The research work will contribute to understand basic mechanism responsible for this mismatch of prediction and reality. Based on this improved understanding this work will suggest a improved approach on predicting effect of toxicants on ecosystems. The methodological approach includes literature analysis, laboratory and mesocosm experiments The conceptual approach is to assess, how toxic effects propagate through different levels of biological organization.
