Course content
|
The course covers most environmental chemical topics focusing on metals in the environment and provides deeper understanding of pollutants occurrence, origin and processes in the environment, biota, soil, air and water. The methodologies for chemical analysis and isotope tracing is also included. 1. Introduction to biogeochemistry of metals. Metals and compounds in the environment. Bioavailability of metals. 2. Trans-boundary air pollution with metals. 3. Deposition of metal pollutants into soils. Factors influencing the behaviour of metal pollutants in a soil system. 4. Mobility of metal pollutants in a soil system. Direct and indirect methods, suction cups for pore water sampling. 5. The forms of metal pollutants and methods of their study. Direct and indirect methods, single and sequential extraction schemes. Speciation analysis. 6. Soil compounds and metal sorption/desorption behaviour. Surface complexation models. 7. Remediation of contaminated soils, chemical and fyto- stabilizations. 8. Isotope fingerprints of metal sources. Comparison of an inductively coupled plasma- and thermal ionization mass spectrometry.

Learning outcomes
|
Students will have knowledge of environmental chemistry focused on metals and their behaviour in environment, as well as decontamination technologies, waste handling technologies and environmental protection. The further aim of the course is to provide students comprehensive knowledge of environmental protection. The course involves areas of atmosphere, water and soil contamination and protection. Students are also oriented towards industrial toxicology, ecotoxicology, environmental analysis, decontamination technologies and environmentally oriented legislation.
Students are well oriented in areas of atmosphere, water and soil contamination with metals. They are able to predict metal behaviour with respect to environment characteristics. They know about decontamination technologies available in recent time. Students are able to critically assess the environmental contamination based on data from up-to-date analytical technics.
