Course content

The course is an introduction to general principles in toxicological risk assessment, both ecotoxicology and human toxicology. The practical use of these principles for protection of the environment and humans will be in focus. The risk assessment principles are well standardized internationally, and in the course, the OECD test protocols and EU's technical guidance system will be elucidated. In addition to lectures on the interaction between toxicology and the society, the students will do practical data exercises of risk assessment, and will present this and project to the other students.

After finishing the course, you will:

  • have knowledge on general principles for risk assessment in both human and ecotoxicology.
  • have knowledge on national and international principles for the assessment, test protocols and legislation
