BIOS5412 – Toxicants in Ecosystems and Humans: Exposure and Accumulation
The course gives insight into how toxicants are distributed in the environment and accumulated by humans and other organisms. The course focuses on mechanisms and processes that are important to understand distribution and accumulation of toxicants and how these processes are affected by other stressors, physiological and ecological adaptations, life history traits and the phylogenetic history of the organism. The course encompasses both different ecosystems, including organisms, and humans.
The course will provide in-depth knowledge of how toxicants are distributed in the environment and different ecosystems, and how they accumulate in plants, animals and humans.
After completing the course, you will have knowledge:
- concerning important drivers for distribution and accumulation of toxicants, including environmental, chemical, physical, physiological and ecological factors.
- about different methods used to monitor the toxicant exposure in ecosystems and humans, as well as describing the extent of uptake and biomagnification.
- about exposure- and accumulation-models, statistical tools within ecotoxicology, as well as an understanding of different accumulation metrics and how to calculate them.
Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.
