Module aim (aims)

The course introduces different types of toxic threats in the aquatic ecosystems (e.g. cyanotoxins, toxins produce by eukaryotic algae, heavy metals, ksenobiotics etc) and characterizes their influence on functioning of ecosystems and human health. Moreover harmful algal blooms, biocenotic transformation, reaction of organisms to different toxins are broadly presented as well as detection methods and economic cost of toxic threats.

Pre-requisites in terms of knowledge, skills and social competences (where relevant)

General knowledge in hydrobiology and ecologyGraduate students (B.A.)
