Geochemistry and Soil Pollutants   (1512S)

Academic year:

2012/2013.

Attendance requirements:

1102S + 1201A

ECTS:

7

Study level:

Study program:

Teacher:

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

Assistants:

Hours of instruction:

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

Goals:

With the course Geochemistry and soil pollutants a student has the possibility to meet the geosfere, its structure and its composition. He meets transformation of organic substances in geosfere, and, on that way, he has formed the full picture concerning the organic carbon cycle. Additionally, a student has met the soil as a nature resource, which has a very big importance and which is exhibited by a lot of type of pollutants.

Outcome:

Knowledge of these topics is necessary for forming a full expert for environmental chemistry because geosphere (including soil) is on of the most important segments of the environment.

Teaching methods:

Lectures, exercises with colloquies (every exercise is one colloquia).
