Course for environmental risk 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 both exposure and effects in two parallel modules and offers a combination of lectures and hands-on exercises. This combination of theory and practice is an excellent opportunity to deepen your knowledge and understanding of exposure and effect assessment and to improve your skills.

Content & Approach

This course offers a hands on training by the combination of lectures, exercises and discussions in two parallel modules, A (Exposure) and B (Effects). Back home you can apply new knowledge and approaches straight away in your daily work. 

Module A: Exposure assessment of groundwater and surface water (Introductory course)

The content of module A focuses on leaching and aquatic exposure, including emissons from greenhouses, of plant protection products. You will apply the following models: GeoPEARL, PEARL, FOCUS_TOXSWA and GEM. Hands-on exercises include the determination of pesticide input parameters and interpretation of the results in relation to the applied input parameters and in relation to regulatory use. Please note that module A is an introductory course.

Module B: Aquatic Effect Assessment (Advanced course)
The content of module B focuses on aquatic effect assessment and the linking of exposure to effects, including consistency of the tiered approach, issues in each of the tiers, geomean approach, species sensitivity distributions, modified exposure tests, micro- and mesocosm studies, realistic worse-case exposure profiles, statistical power, recovery option and models (TK-TD and population models).

Target audience

This course aims at professionals using guidance for the authorization of plant protection products:
-  Regulators working for admission authorities who apply the guidance for their dossier evaluations
- Consultants and business representatives working for industry and or consulting agencies who apply the guidance for dossiers (evaluation, preparation and submission)
- Scientists performing lower and higher tier fate and effect experimental and modelling research, applying the latest and newest available guidance

Module A is an introductory course and handles exposure of plant protection products. For module A we ask at least a Bachelor degree or similar in natural sciences and experience with at least one of the exposure models.

Module B is an advanced course and handles aquatic effect assessment at the applied level. We ask at least a Bachelor degree or similar in natural sciences and in-depth  experience with the Tiered approach for effects on the aquatic ecosystem.

The importance of environmental risk assessment knowledge

The governmental guidance regarding the authorization of plant protection products is regularly updated to keep pace with scientific developments. New guidance may lead to questions on how to apply these guidance properly and how to apply new approaches, for example higher tiers in the risk assessment. Highlights are the new guidance for aquatic organisms (EU), new tools for exposure in surface waters (EU), greenhouse emissions in NL, leaching to groundwater (EU and NL).
