Teacher:

Ksenija A. Stojanović, Ph.D.
full professor, Faculty of Chemistry, Studentski trg 12-16, Beograd

Hours of instruction:

Weekly: three hours of lectures + four hours of labwork (3+0+4)

Goals:

The main goal of the course Geochemistry and Soil Pollutants is to introduce students to the geosphere, particularly its structure and composition. Students learn about the transformation of organic substances in the geosphere and about the natural carbon cycle. Additionally, students learn about the soil as a natural resource which is very important and which is subjected to various types of pollution.

Outcome:

The knowledge gained in this course greatly helps students’ further education in the field of environmental chemistry because the geosphere (including soil) is one of the most important segments of the environment.

Teaching methods:

Lectures, experimental work, progress tests.
