Applied Geochemistry

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 affecting the Earth on a local, regional and global scale. Concerns about antropogenic impact on the atmosphere, the hydrosphere, the lithosphere and potentially toxic effects on the biosphere have raised the need for environmental forensics. In environmental forensics, stable isotopes, concentrations of metals and mineral identification are used to trace the sources of pollution and transport routes in the environment. Over the past 10-15 years, the topic has been broadened from having previously worked mainly with the mining industry's environmental issues to applications in infrastructure and society building, such as environmental issues linked to hydropower development, forestry, acid sulphate soils and sulphide-bearing rocks.

In Agenda 2030, the UN sets 17 Global Goals for an economically, socially and environmentally sustainable development. Applied geochemistry focuses in particular on the three goals 6) Clean water and sanitation for everyone, 9) Sustainable industry, innovations and infrastructure and 13) Climate Action.

"Here we want to show everyday life to us teachers, students and researchers who work with the environment and water within the subject applied geochemistry. There will be contributions from field exercises, study visits and lab exercises at Luleå University of Technology, but also with research results, says Lina Hällström, researcher and teacher at the Master Programme in Natural Resources Engineering.

As one of a total of two projects, Lina Hällström has been awarded SGU's research grant in 2022 of SEK 2,815,000 spread over 2.5 years.

Mining and environmental cooperation with Ghana

A research group from applied geochemistry at Luleå University of Technology has just returned from Ghana, where a new joint research and education collaboration has been initiated. It is about increasing the efficiency of metal extraction and reducing the environmental and health risks of mining in Ghana.

Reusability of sulphide-bearing rock material

In infrastructure and development projects, large amounts of rock and soil masses are handled. The masses that arise in the projects can often be reused on site or in other projects in need of rock material, provided that the material meets the set technical and environmental requirements.
