Course on Aquatic Effect Assessment of Plant Protection Products

Do you want to apply existing guidance and new approaches in risk assessment? But don’t know how? In the authorization of plant protection products the potential risks of active ingredients and products for the environment are assessed at EU and MS level using governmental guidance. This course focuses on aquatic effects and offers a combination of lectures, hands-on exercises and virtual classroom. This combination of theory and practice is an excellent opportunity to deepen your knowledge and understanding of aquatic effect assessment and to improve your skills.
