This project investigated the usefulness of single-species laboratory tests and outdoor multiple-species mesocosms to improve the understanding of pesticide mixture effects on aquatic ecosystems. Results indicate that both approaches should be used in a complementary manner to develop a weight-of-evidence approach. Further, the integration of sublethal endpoints in pesticide monitoring could improve identification of environmentally realistic and low-level pesticide concentrations and potential detrimental effects on aquatic environments.     «
