Study program:

Environmental Chemistry: 1. year, winter semester, elective (E51S2) course

Teacher:

Konstantin B. IlijeviŠ, Ph.D.
assistant professor, Faculty of Chemistry, Studentski trg 12-16, Beograd

Assistant:

Jovana P. RoganoviŠ, Ph.D.
scientific associate, Faculty of Chemistry, Studentski trg 12-16, Beograd

Hours of instruction:

Weekly: four hours of lectures + two hours of exercises + three hours of labwork (4+2+3)

Goals:

Monitoring of soil, water and air is a legal obligation arising from the legislation of both the Republic of Serbia and the European Union. Monitoring is, by its nature, more complex than classical analytical measurements or analyzes performed within scientific research, therefore conducting monitoring requires additional professional development. The objective of the course is to provide students with additional knowledge and competences that will enable them to find employment more easily and successfully work in accredited laboratories (which are an indispensable element of any monitoring program). The course should provide the necessary knowledge related to the validation and verification of analytical methods (determination of measurement uncertainty, detection and quantification limits, accuracy, reproducibility and precision of the method), which will be determined not only theoretically, but also through practical examples.

Outcome:

The student is able to successfully complete the accreditation process for a given analytical method, use standard procedures, determine and pass judgment on environmental quality parameters. Upon completion of the course, students will be familiar not only with the principles of basic instrumental analytical techniques which are routinely used in environmental monitoring, but also with their limitations, disadvantages and benefits. The student is able to perform all operations within the monitoring of eco-chemical parameters in accordance with best laboratory practice which include: sampling, sample preparation, sample analysis, processing and interpretation of measurement results.

Teaching methods:

Lectures, theoretical exercises, labwork, semester papers.

Extracurricular activities:

Collecting of the literature, preparing reports and presentation, learning for exams.
