Course content

The course can be used as part of the curriculum for a MSc or PhD in toxicology or ecotoxicology. The course is offered in the autumn semester following the course in general toxicology (BIO 4500). The course can form part of the theoretical basis for recognition as an EUROTOX-registered toxicologist.

Learning outcome

The course offers advanced subjects in aquatic ecotoxicology, including bioaccumulation, trophic transfer of contaminants, quantitative methods including multivariate statistics and mechanistic modelling, effects of environmental contaminants, specific pollution challenges, and in vitro methods. Upon completing the course students should achieve an up-to-date knowledge of the most important areas of ecotoxicology.


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.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.

PhD-students must register for BIO9550.

The courses BIO4550 and BIO9550 have common admission. Applicants are ranked by the following criteria:
1. PhD students and master students at the MN faculty who have the course as part of the approved curriculum.
2. Other PhD students and visiting PhD students.
3. Students with admission to single courses on master’s level and exchange students
4. Applicants are ranked by credits in each group; all applicants within 1st rank before applicants in 2nd etc. If admission is limited to a fixed number of participants, admission will be decided by drawing lots for students who are ranked equally
