This project addresses the need to assess the environmental and health risks of chemicals used in food production, since their release into the environment may lead to different ecological effects. The occurrence and effects of selected chemicals on wildlife and humans will be addressed to provide data sets, which are necessary for scientifically-based risk assessment. Special emphasis will be put on the combined effects of environmentally relevant mixtures. A combination of state-of-the-art methods will be applied to predict synergistic and/or additive effects of combined exposure. Development and implementation of new technologies for waste treatment and re-use of food industry by-products by converting them into value-added items will also be a significant task.
