Aims
The aim of the course is to clarify the essence of ecotoxicological work; The use of bioindication systems as a tool to assess the effects of chemical substances or contaminated matrices present in the environment on different biological species. To predict the effects not only at the person level but also at the ecosystem level, i.e. to assess the impact of chemicals on ecosystem balance and vulnerability. To give an overview about the tests of ecotoxicity and their use at waste management and environmental protection.
1. The student gains knowledge about principles and performance of ecotoxicological tests.
2. The student Get acquired with all types of tests that are recommended by the legislation of the Czech Republic and the EU a OECD.
3. The student will master the test evaluation procedures, including interpretation of their results.
4. The student will acquire knowledge enabling the use of ecotoxicological tests to assess the level of environmental contamination in environmental monitoring.
5. Knowledge of legislation and overview of the wide range of ecotoxicity tests will also enable the student to apply them in waste management or environmental protection.
