Cíle předmětu

After this course, students should be able to:
- describe and understand basic principles of ecotoxicology
- discuss and explain environmental stressors (chemical compounds, physical and biological stressors)
- classify and interpret adverse effects (organisms are understood as receptors of the stress) at different levels and for different organisms (bacteria, algae, plants, invertebrates, vertebrates including man)
- explain and use methodological approaches in ecotoxicology
- solve practical problems of the ecotoxicology applications
- explain the legislative framework of ecotoxicological biotests
- discuss the approaches for evaluation of ecotoxicity of chemical compounds and hazardous materials
- know the guidelines, their structure and system of standardized ecotoxicological biotests
- suggest the optimal test or battery of tests according to the requirement of the study
- plan sampling strategies for various biotic and abiotic matrices
- suggest bioindication and biomonitoring approaches for studies in situ
- determine and calculate the crucial parameters characterizing the toxicity from the test results
- combine the information obtained by biotests with data from chemical analysis for effective risk assessment of polluted environmental matrices
- discuss basic principles, specifics, methods and approaches of aquatic and soil ecotoxicology
- characterize main water and soil properties and discuss their relations to the effects of contaminants
- discuss factors affecting bioavailibility and fate of pollutants in the aquatic and soil environment

Výukové metody

Education is performed as lectures (weekly or in blocks) with Powerpoint presentation. Understanding of mechanisms and consequences is emphasized. Students are frequently asked questions to think about actual topic. They are encouraged to ask questions and be in interaction with the lecturer. Students perform independent seminar project (1x during the semester). In laboratory exercises (blocks at the end of semester) basic methods related to the field of the course will be demonstrated.

Metody hodnocení

Attendance of the lectures is not mandatory but strongly recommended for fluent understanding of the educated subjects. During the lectures, students are asked about subjects of past lecture. Final assessment (at the end of semester) is by written examination or oral exam
