DESCRIPTION OF ACTIVITIES:
The activity carried out includes numerous applications of geochemical analysis concerning the study of natural systems
The activity of the laboratory includes various geochemistry applications in the study of natural (e.g., active volcanoes, hydrothermal and geothermal systems, surface water, groundwater) and anthropogenic (e.g. industrial plants, MSW landfills, mining sites) systems.
This activity is the result of decades experience in the development of techniques for sampling and analysis devoted to the determination of inorganic and organic components of fluids (water and gas) and rocks.
The laboratory staff is highly trained to carry out studies in the following fields of investigation:
- Quality of water resources
- Exploration Geochemistry
- Air quality
- Geochemistry of Volatile Organic Compounds
- Geochemistry of MSW landfill sites
- Urban geochemistry
Our staff also offers the opportunity to provide the following services:
- In situ measurements of diffused gas flow from the soil (CO2, CH4, hydrocarbons and Hg0)
- In situ measurements of environmental tracers in air (CO2, CH4, H2S, SO2 and Hg0)
