In this module, students will be lectured on the basics of risk assessment for plant
protection products. The most important aspects and definitions in the field of exposure,
selection of representative test species, (statistical) data evaluation and risk assessment
will be discussed. The for registration purposes considered organism groups, i.e. birds,
mammals, aquatic organisms (incl. fish, invertebrates, primary producers), honeybees,
soil organisms (incl. earthworms), non-target arthropods and non-target plants, and
the corresponding data requirements will be reviewed. Specific aspects of exposure
and assessment of each of these organism groups will be discussed. Furthermore, the
importance of ecotoxicology in the registration process of a plant protection product will
The theoretical basis will be handled in the lectures and subsequently some aspects will
then be applied in the practical part. This includes:
- Methods in ecotoxicology (e.g. standardisation and quality of testing)
- Exposure pathways, bioavailability
- Selection of test species and testing methods
- Risk assessment and risk management
In the practical part, students will learn to design, conduct and evaluate acute toxicity
tests with plant protection products in the laboratory. It is planned to use test species
from the group of arthropods, mainly insect larvae (depending on animal availability).
The aim of the tests is to obtain a dose-response relationship and (mathematically)
derive EC50 or LC50 values and also, if the data permit, to (statistically) derive NOEC
and LOEC values.
Finally, a choice of publically available European registration dossiers will be reviewed
and critically discussed.
To gain a basic knowledge of ecotoxicology and understanding its principles and
associated testing and ecological risk assessment methods, specifically for application
to plant protection products.
Knowledge of ecotoxicological testing methods and their evaluation for the risk
assessment of plant protection products.
