Abstract: Pesticides are effective in protecting crops against diseases and pests and ensuring high food and feed yields, on the other hand they are bound to be toxic against target organisms but can also harm non-target organisms. Actually, most environmental scientists agree that pesticides, globally and deliberately introduced into the environment in large amounts, contribute to the insect decline on a regional, continental and global scale. With a focus on pesticides I will report on gaps in their current environmental risk assessment: the discrepancy in fate and effect studies between single substance testing, i.e., the typical scenario when performing authorization studies, and pesticide mixtures, which occur in every agricultural practice, the disregard of further stress factors (multiple stress), and necessary developments in the persistence assessment of chemicals.
