About this course
- Students will acquire advanced knowledge about principles of ecotoxicology and the main challenges in the field.
- Students will have in-depth knowledge of main pollution sources in the environment ( e.g., metals and heavy metals, radionuclides and organic pollutants), about typical concentration levels, different species, mobility and transport processes in different ecosystems, biological uptake, bioaccumulation and biomagnification in organisms and physiological and biological effects.
- Students will be able to assess the short and long-term impact on man and the environment from contamination, and for some pollutants evaluate alternative countermeasures to reduce the impact in different ecosystems.
- Students will be introduced to modern analytical techniques applied within the field, and how ecotoxicological tools are used to evaluate risks and to identify chemical compounds being of main importance to the total cumulative effect and how effects can be identified by biomarkers.
- Students will acquire an understanding of why assessments of long-term effects of pollutants is required to prevent negative impact onto vulnerable ecosystems.
Environmental chemistry and ecotoxicology are experimental disciplines, lectures, colloquia and exercises are closely integrated. The lectures give a theoretical background for the practical training.
Lectures: focus on naturally occurring and anthropogenic sources contributing to contamination of different ecosystems, soil, water, vegetation, animals etc. The speciation of contaminants influences the mobility and biological uptake (toxicokinetic), and effects in organisms (toxicodynamic). Toxic effects from molecular to population and ecosystems, responses and multiple species and life stage concept. Mixtures and multiple stressors and cumulative effects. Risk assessments.
Colloquia on selected topics to be discussed and presented by the students.
Practical exercises include:
- Water sampling and analyzing of water quality to be used in the field to evaluate possible impact of pollution.
- Tissue sampling for determination of contaminants in fish organs according to an international protocol. A certificate is issued for the sampling (voluntarily).
Case study: Assessment of pollution and risks based on data from measurements of contaminants and biomarkers in aquatic ecosystem - group presentation.
- Discussions in colloquia and assistance through laboratory courses. Recordings of lectures are placed on CANVAS as far as possible. Lecturers are available for questions..
