Learning outcomes
|
The subject on environmental analytical chemistry has expanded in recent years into a fully grown scientific field. This course represents introduction into a theoretical basis of the distribution of the chemical compounds between the compartments of the ecosystem and overview of the isolation and concentration of the pollutants from the atmosphere, water and soil, their determination with the modern instrumental techniques with the emphasis on the chromatography and its connection with the spectroscopic techniques.
The student is able to understand the occurrence of chemical substances in environmental compartments, is able to independently assess the possibilities of their movement through environmental compartments. The student is acquainted with basic physico-chemical properties of pollutants - especially emerging pollutants, is able to find out their toxicity, understands the nature of toxicity tests. He/she masters the principle of air, water and soil sampling, pre-concentration of substances and methods of their determination.
