The course is also offered to the students of the fields other than those the course is directly associated with.
fields of study / plans the course is directly associated with
Course objectives
The aim of this course is to obtain knowledge and deeper understanding in the area of key characteristics of aquatic ecosystems, factors affecting their stability, impacts of various stressors and environmental factors on aquatic ecosystems, approaches to their assessment and regulatory principles of their protection. An important goal is to understand current problems of aquatic pollution, methods of its monitoring and the ways of its reduction.
Learning outcomes
After this course, students should be able to:
- define aquatic ecotoxicology and discuss its basic principles;
- classify the aquatic environment according to its characteristics;
- characterize main water properties and their relation to the state of the ecosystem;
- recognize main aquatic contaminants;
- discuss factors affecting bioavailability and fate of pollutants in the aquatic environment;
- propose and interpret tests for evaluation of toxicity in aquatic environment also in legislative context;
- plan sampling strategies for various biotic and abiotic matrices;
- assess characteristics, contamination and ecotoxicity of sediments;
- interpret the results of bioindication and biomonitoring in aquatic environment;
- evaluate the potential effects of stressors on ecosystem level;
- explain principles of the Water Framework Directive – evaluation of chemical and ecological status;
- compare the various approaches for waste water treatment;
- recognize and discuss up-to-date problems of aquatic environment – such as new types of pollutants, endocrine disruption, cyanobacterial water blooms;
- assess the influence of multiple stressors in aquatic ecosystems;
Syllabus
  • 1) Introduction and the goals of class, basic terminology and definitions, classification of waters, components of aquatic ecosystem
  • 2) Characteristics of water, stratification in reservoirs and rivers, types of flow, carbonates, redox potential a pH in ecotoxicology of aquatic ecosystems, circulation of major biogenic elements
  • 3) Factors affecting bioavailability and fate of compounds in the aquatic environment
  • 4) Tests of negative impacts on aquatic environment. Laboratory and field models, sources of variability and uncertainty, legislative context
  • 5) Fish in aquatic system - reproduction, population structure, embryotoxicity, bioaccumulation, bioconcentration. Methods, organisms suitable for evaluation of bioaccumulation of xenobiotics in aquatic systems, tests, data analysis, interpretation
  • 6) Sampling of plankton, benthos, fish communities, macrophytes, sediments, water. Discrete, continuous and passive sampling (SPMD, DGT, POCIS etc.)
  • 7) Sediments as memory of aquatic ecosystems - advantages, disadvantages, sampling, storage, detection of toxicity, fauna and flora of sediments, interpretations
  • 8) Adaptation and oscillation – impact of flow, light, season

Teaching methods
The classes are composed of lectures and associated discussions.
Assessment methods
Examination usually takes place at the end of each semester or when the course is completed. The final evaluation is based on a written test containg 30 questions. Student needs to reach at least 60% of total score in this test.
