Subject aims expressed by acquired skills and competences
The utilization of knowledge and application of natural relations from geochemical behaviour of elements in Earth crust in to the areas influenced by antropgenic activity. Understanding of the principles of risk elements during thermic processes by the waste processing. Identification areas of contamination in surroundings of landfills and old ecological loads with utilization of geochemical models (SURFER).

Summary
The course „Geochemistry of Environment“ is focused on geochemical processes
and principles of migration of both chemical elements and organic pollutants in individual components of environment (water, soil, atmosphere) including
anthropogennous processes – waste production.
