Course/Module description:
Basic concepts in aquatic geo-chemistry, buffer capacity of natural waters, acid rain and acid waters, redox processes in lakes, marine environment and groundwater, photochemical processes in natural waters and sediments, colloids as components of naturals waters, carbonate, iron and sulfur geochemistry in naturals waters and sediments, chemical weathering of minerals, aquatic biochemistry, pollution of natural water bodies, aqueous geochemistry radionuclides, water quality monitoring, chemical composition and contamination of groundwater, chemistry and pollution of marine environment.
Course/Module aims:
to facilitate an advanced understanding of geochemical processes in natural water bodies
Learning outcomes - On successful completion of this module, students should be able to:
• Understand the mechanisms of geochemical processes occurring in different components of hydrosphere
• Understand the effect of variable geochemical processes on the composition of water bodies
• Understand the close correlation between geochemistry of water bodies with environmental chemistry.
Attendance requirements(%):
100
Teaching arrangement and method of instruction:
Lectures, and seminars every week. Homework will include exercises (questions, calculations), and reading scientific papers related to the topic of the lectures. During the seminars, exercises will be checked and students will present the papers and answer the questions. Discussions of the results published by the other researchers will help students to develop scientific thinking, and thus might be useful for their M. Sc. studies.
Course/Module Content:
• Lecture 1. The hydrosphere and basic concepts in aquatic geo-chemistry. Natural water bodies – outlines of different hydro-chemical natural environments.
• Lecture 2. Buffer capacity of natural water. Acid rains and acid waters and the impact of the water acidification on the geochemical processes.
• Lecture 3. Redox processes in natural waters. Redox conditions and processes in lakes, marine environment and groundwater.
• Lecture 4. Photochemical processes in natural waters. Heterogeneous photochemistry.
