Course content

The course will cover basic toxicology and ecotoxicology, including how toxic substances are taken up in the organisms, distributed, biotransformed and excreted, how toxic substances react with biomolecules and downstream consequences for the organism, as well as knowledge about toxic substances, e.g. metals, organic contaminants, and pesticides. The course aims to provide a holistic view of the topic by bridging human toxicology and ecotoxicology.

BIO4500 can be taken in the same semester as BIOS5411 – Toxicants in ecosystems and humans: Effects and BIOS5412 – Toxicants in Ecosystems and Humans: Exposure and Accumulation.
