Summary
The subject is focused on deepening knowledge in the field of chemistry of water, soil and air, i.e. chemical reactions occuring in these systems, further in the field of pollution of these compartments of the environment with interconnection to selected technologies having a potential to significantly affect quality of the environment. Introduction to potential environmental risks of the above mentioned innorganic and organic pollutants will be included as well.
