Analytical Environmental Geochemistry

Basic principles of thermodynamics equilibrium and kinetics. Redox processes in natural systems. The system CO2 carbonic acid and carbonate, natural waters pH. Box models and geochemical cycles. Metals, sources, anthropogenic impacts, speciation, enrichment factors, ion exchange, sorption, desorption, case studies.

Objectives

• Understanding of Service of natural systems and the impact of humans on them. • Understanding the impact of the exploitation of mineral raw materials and energy resources in the environment. • Understanding the purpose of natural materials in the environment.

Prerequisites

Typically there are no pre requisites, but knowledge of the following courses is considered necessary: a) XHM101 Inorganic Chemistry (1st semester) and b) MOP304 Geochemistry (6th semester) of Undergraduate Studies of the School of Mineral Resources Engineering.
