- Course objectives
- The main objective of this class is to get an overview and deeper expert knowledge and competences in the field of ecotoxicological assessment of hazardous properties of various types of materials and chemical compounds
At the end of this course, students should be able to:
- explain the legislation framework of ecotoxicological biotests, the approaches for evaluation of ecotoxicity of chemical compounds and hazardous materials in CR and EU
- know the guidelines, their structure and system of standardized ecotoxicological biotests
- discuss the applicability of standard and alternative methods for practice
- select the best approaches and model organisms for ecotoxicological assessment of test materials
- suggest the optimal test or battery of tests according to the requirement of the study
- assemble design of single or multifactorial ecotoxicity tests
- assess the limitations and advantages of bacterial tests for toxicity and genotoxicity
- characterize the most often used batteries of biotests, tests with the model autotrophic organisms (producents) and consuments
- compare the biotests for assessment of toxicity of solid environmental matrices
- describe the options for evaluation of toxicity for higher animals in terrestrial and aquatic environment
- argue applicability and the need of in vitro and in vivo tests for ecotoxicity evaluation
- consider potential influence of other factors on the test outcomes
- 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
- integrate the results from various types of biotests for the purpose of risk assessment
- analyze in detail and critically interpret the biotest outcomes in broader context - Syllabus
- 1. Introduction to the class, terminology, needs, requirements and classification of ecotoxicological biotests

- Teaching methods
- Education is performed as lectures with Powerpoint presentations and discussions of the lecture topics. It includes homework assignments where students need to elaborate answers to assigned set of questions. Every student also prepares Power Point presentation on a selected biotests based on individual study of the guidelines and other materials.
- Assessment methods
- During school term every student prepares 10 min presentation for his/her colleagues. The gained knowledge is supported by two home assignments with sets or questions during the school term. The presentation and assignment are required for the credit. The final evaluation is based on written exam, where student needs to reach at least 60% of total score, followed by oral examination.
