Exams after the reopening

As a general rule, exams will be conducted without physical attendance in the autumn of 2021, even after the reopening. See the semester page for information about the form of examination in your course. See also more information about examination at the MN Faculty in 2021.

Course content

The course gives insight into how toxicants affects humans and the environment, with a particular focus on individual effects. Toxicants affect many of the same processes in different organisms and the course will discuss similarities and differences between different species, using mammalian toxicology as a starting point. The course includes aspects of both ecotoxicology and human toxicology.

Learning outcome

The course will provide in-depth knowledge of how toxicants affect humans and other organisms.

After completing the course, you will:

  • Have knowledge of the mechanisms of toxicity for different toxic substances, including endocrine disruption, genotoxicity, reproductive toxicity, immunotoxicity, neurotoxicity, developmental toxicity and behavioural toxicity.
  • Have knowledge of the metabolism of toxicants in different species.
  • Have knowledge about the effects of toxicants on a molecular and cellular level, on individual health, on populations in nature and on communities, as well as the use of biomarkers.
  • Understand the importance of different groups of toxicants for human health and the environment.
  • Expertise in conveying toxicological knowledge at the Master´s level

Admission to the course

PhD candidates from the University of Oslo should apply for classes and register for examinations through Studentweb.

If a course has limited intake capacity, priority will be given to PhD candidates who follow an individual education plan where this particular course is included. Some national researchers’ schools may have specific rules for ranking applicants for courses with limited intake capacity.

PhD candidates who have been admitted to another higher education institution must apply for a position as a visiting student within a given deadline.

Master's students must register for BIOS5411 – Toxicants in ecosystems and humans: Effects.

The courses BIOS5411 and BIOS9411 have common admission. Applicants are ranked by the following criteria:

1. PhD candidates and master's students at the MN faculty who have the course as part of the approved curriculum.

2. Other PhD candidates, master students and visiting PhD candidates.

3. Students with admission to single courses on master’s level and exchange students

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
