Applied geochemistry focuses on studies of the presence of elements and the geochemical processes that take place in rock, soil and water at Earth's surface.
Humans are today a significant geological factor that affects the Earth on a local, regional and global scale. Concerns about man's impact on the atmosphere, hydrosphere, lithosphere and potentially toxic effects on the biosphere have actualized the need for environmental geochemistry. Research and education in environmental geochemistry relates to environmental issues linked to the mining industry, infrastructure construction and community building, hydropower development, forestry, acid sulfate soils and sulfide-bearing rocks. In environmental forensics, we use isotopes, multi-element analyzes and mineral identification to trace pollution sources, mobility and geochemical processes in both natural and affected systems.
