Learning outcomes
|
The aim of subject is detailed knowledge of the effect of pollutants on the aquatic environment and above all on fish as a managing agent of organisms in aquatic ecosystem. Special attention will be paid on the entrance of pollutant into water ecosystem, and their action mechanism on water organisms and diagnostics of poisoning.
The main objective of this class is to get an overview and deeper expert knowledge and competences in the field of toxicological assessment of hazardous properties of pollutants on aquatic organisms. At the end of the course, students should be able to understand the concept of aquatic toxicology and assessment of pollutant. Students will be able to explain the effects of pollutants on living aquatic organisms. Students can discuss and interpret the general principles of aquatic toxicology and will manage the evaluation and use of methodologies in toxicology, which to predict the effects of toxic substances. Students will be able to justify application of aquatic toxicology and application of knowledge in practice.
