Course objectives
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
Syllabus
  • 1. General ecotoxicology
  • • history and present ecotoxicology frame; ecotoxicology definitions, links, relations, ecotoxicology areas and types
  • • chemical compounds in ecosystems; single chemical vs. mixtures; environmentally relevant properties of chemical compounds; fate of chemicals in the environment; biotic transformations; major classes of important contaminants – sources, fate and effects
  • • biological systems in ecotoxicology; exposure-dose-response concept; toxicokinetics and toxicodynamics; acute and chronic toxicity vs. genotoxicity vs. carcinogenity; biomarkers; hierarchy of biological systems
  • • (eco)toxicological effects at various levels; subcellular and cellular level; modes of toxic action; mutagenicity and genotoxicity; organ level; organismal level; population, community and ecosystem level; levels of trophic chains: producents, consumers, predators, destruents
  • 2. Experimental approaches of ecotoxicology
  • • laboratory testing vs. in situ studies vs. biomonitoring - design and principles; standardization (ISO, OECD, US EPA); factors affecting test results; data analysis and interpretation; good laboratory practice
  • • laboratory biotests; classification and hierarchy of tests; test batteries; parameterization of effects - derivation and interpretation of ECx, LCx, LO(A)EL, NO(A)EL values; needs and requirements of the tests; alternative biotests
  • • methods for testing toxicity of chemicals and environmental samples - representatives and examples; multispecies testing - laboratory microcosms; tests with destruents; genotoxicity tests; tests with producers and consumers
  • • ecological methods of in situ studies; design and needs; measured parameters; characteristics of community structure; problems and specifics of bioindicators; bioindication of air quality, soil quality and water quality
  • • evaluation of biomarkers and toxicity mechanisms; principles, methods and approaches; endocrine disruption; in vitro testing
  • • sampling, handling and preparation of samples from various environmental matrices for ecotoxicological assessment, sampling design and strategies
  • 3. Aquatic and soil ecotoxicology
  • • classification of waters; properties of aquatic ecosystems; factors affecting the fate of contaminants and their effects; sediment; properties of sediments and their specifics
  • • problems in aquatic ecosystems; cyanobacterial blooms; pharmaceuticals and personal care products; endocrine disruption; Water Framework Directive 2000/60 EEC
  • • toxicity tests for aquatic ecosystems; in situ studies; using plankton, benthos, algae, macrophytes, invertebrates, vertebrates in aquatic ecotoxicology; passive sampling of pollutants
  • • soil properties and functions; problems of soils, their contamination and protection of soils; legislative framework of soil ecotoxicology • fate of contaminants in soils; bioavailability
  • • effects of contaminants on soil microorganisms, invertebrates and plants; methods, examples, principles and interpretations; bioassays and bioindication
  • 4. Applications of ecotoxicology
  • • regulatory frame for ecotoxicology; role of ecotoxicology in environmental protection

Teaching methods
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.
Assessment methods
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
Language of instruction
English
