The aim of this course is to explain the principles of toxicity testing mainly as a tool for determination of effects of chemical compounds present in the environment and their impact on different biological species and ecosystem balance. Besides chemical analysis, estimation of ecotoxicity of chemical compounds is an important part of environmental monitoring. Broad spectrum of toxicity tests and their application in waste management or environemntal protection is demonstrated. The student will be guided through the whole process of toxicity testing from sample collection, planning of experimental design to final data interpretation.

Students will be able to: Interpret dose-response curve and other toxicity indexes like EC50, NOEC, LOEC etc. Describe design of the toxicity test and choose its suitable process. Propose a suitable test battery for a certain typ of study. Students will get knowledge of broad variety of toxicity tests at different trophic levels.

Examination requirements:
The exam starts with written part (student must get min 50 points from 100). After successful written part the oral exam follows. The exam is focused on topics within the syllabus and the recommended literature. Last update: Kubová Petra (06.03.2019)

We recommend practicing in e-learning before the exam. Any consultations (even in written form by email) should be requested at least 7 days before the scheduled exam. Otherwise, there is a risk that the teacher will not have enough time for corrections. However, any practice in e-learning is optional and does not affect the outcome of the final exam. The exam starts with written part (student must score at least 50 points from 100). After successful written part the oral exam follows. The oral part of the exam is optional for capacity reasons. The exam is focused on topics within the syllabus and the recommended literature. Last update: Mocová Klára Anna (31.08.2024)
