Course objectives
At the end of the course, students should be able to:;
- describe and understand basic principles of ecotoxicology
- discuss and explain environmental stressors (chemical compounds, physical and biological stressors)
- clasify and interpret adverse effects (organisms are understood as receptors of the stress) at different levels and different organisms (bacteria, algae, plants, invertebrates, vertebrates including man)
- explain and use methodological approaches in ecotoxicology
- solve practical problems of the ecotoxicology applications
Syllabus
  • 1 - history and present ecotoxicology frame ecotoxicology - the science of effects of (chemical) stressors on ecosystems and their living parts (organisms); knowledge base of ecotoxicologist; ecotoxicology vs. (human) toxicology; relations and connections between ecotoxicology and other biological and environmental sciences; terminology of toxicology and ecology. retrospective and prospective ecotoxicology; types of ecosystems and ecotoxicology (aquatic and terrestrial ecotoxicology); 2 - chemical compounds in ecosystems environmentally relevant properties of chemical compounds (basic and specific descriptors - partition coefficients, sorption constants, lipophility); introduction to principles of study of fate of chemicals in the environment - transport, distribution, transformations; bioconcentrations and bioavailability - specifities of aquatic and terrestrial ecosystems; biotic transformations - biodegradation and metabolism of xenobiotics. 3 - biological systems in ecotoxicology exposure-dose-response concept, toxokinetics and toxodynamics; acute and chronic toxicity vs. genotoxicity vs. karcinogenity; biomarkers; hierarchy of biological systems - specifications and effects of (chemical) stresors in different levels. 4 - effects in various levels of the organism subcellular and cellular level - biochemical and molecular modes of toxic action; mutagenicity and genotoxicity; effects on organ level of auto- and heterotrophic organisms; organismal level - health vs. letality, reproduction and developlmental effects; 5 - effects in various levels of trophic chains ecotoxicology of producents - cyanobacteria, algae, plants ecotoxicology of predators - invertebrates, vertebrates, man as a component of ecosystems ecotoxicology of destruents - bacteria, fungy 6 - (chemical) stress in communities and ecosystems properties, structure and functions of ecosystems, spatial and temproral changes, connections and relationships between components of ecosystems, trophy and food chains; effects of chemical stress, respones and recovery in ecosystem level; aquatic and terrestrial ecosystems, case studies, indicator of ecosystem health; organic pollution vs. toxicity. 7 - experimental approaches laboratory testing vs. in situ studies vs. biomonitoring; experiments of different complexity - design and principles; standardization, reproducibility, and ecological interpretations; biological factors affecting toxicity (nutrition, sex, annual and life cycles ...) 8 - methods in ecotoxicology (I) - laboratory biotests biotests - hierarchy and batteries of tests - trophic levels; studies of effects and their parametrization - derivation and interpretation of ECx, LCx, LO(A)EL, NO(A)EL values. Methods for aquatic and terrestrial organisms - representatives and examples; multispecies testing - laboratory microcosms. microbial ecotoxicology 9 - metody in ecotoxicology (II) - ecological studies metods of in situ studies - types and selection of organisms and exposures, negative-background localities, mesocosms. biomonitoring - field studies, concept of biological integrity, characteristics and parametrizations of community structure; problems and specifities of bioindicators; 10 - major classes of important contaminants: chemical individuals vs. mixtures and complex samples; industrial and urban pollution; basic characterisitics of major classes - sources, fates and effects: inorganic compounds (metals, gases, nutrients - phosphorus, nitrogen); organic pollutants (organic gases, solvents, pesticides, products and byproducts of industrial activities, combustion products). 11 - Applications of ecotoxicology predictive ecotoxicology (principles and characteristics of structure-activity relationship modelling (QSAR) mathematical models for fate and transport of chemicals in the environment and food chains; risk assessment - basic concepts and realization, hazard vs. risk, fate and effects analyses and synthesis - risk evaluation; human vs. ecological risks national and international standards in ecotoxicology, regulatory frame for ecotoxicology, corresponding practical aspects, derivation and interpretation of safety limits or benchmarks.

Teaching methods
Combination of lectures (weekly during whole semester), practical exercises - ecotoxicology tests (block at the end of semester), e-learning materials (within IS.MUNI.CZ), independent seminar project (1x during the semester), continuous check (using Questionaires in the IS.MUNI.CZ (3x during the semester).
Assessment methods
3 online tests during the lectures (ROPOTs - Revision, Opinion Poll and Testing) in the is.muni.cz - results are considered for the final examination). Final exam - written test, followed by oral examination.
Language of instruction
Czech
