The activity of the Environmental Geochemistry and Geochemical Mapping laboratory (GASLAB) is focused on the study on the gas migration processes from shallow and deep geological sources to the surface environment, and their interactions with geosphere, biosphere and atmosphere, as well as with human activity. In particular, the activity is mainly focused on the study of the origin, the analysis of the molecular composition and the spatial distribution of gases occurring in the interstitial soil pore spaces, of the dissolved gases in groundwater, as well as on the measurements of the gas exhalation flux from the soil.
The GASLAB research activity is conducted in different fields of the Geosciences:
- measurements, quantification and mapping (also in urban areas) of non-volcanic and volcanic gas emissions (CO2, CH4 and H2S) for environmental and health protection;
- measurement of endogenous gas emissions in areas at risk of natural and anthropogenic (in urban areas)
- measuring the geogenic radon and thoron (222Rn and 220Rn) potential in soil/rocks and groundwater to quantify the radon risk of an area and to map radon priority areas according to art. 103 of the EU Directive 2013/59/EURATOM (EU-BSS)
- monitoring and mapping of indoor radon and thoron (222Rn and 220Rn) in buildings, cellars and caves to predict the probability of exceeding the Action Level (high radon exposition) in support of the EU Directive 2013/59/EURATOM (EU-BSS)
Geochemical earthquake precursors and microzonation studies:
- shallow measurements for mapping and monitoring of endogenous gas emissions (CO2, CH4, H2, H2S, Rn and He) for the identification and study of buried/exposed active faults in seismogenic areas
- measurements and bottom-up quantification of natural (CH4 and CO2 from gas seeps) and anthropogenic (CH4 from boreholes, pipelines) greenhouse gas emissions
- site selection and monitoring for CO2 geological sequestration, hydrocarbon and geothermal exploration researches.

The GASLAB is equipped with the following portable measuring devices. The goal is to provide and develop innovative analytical and experimental methods in order to improve the quality and quantity of measurements, reducing acquisition times, facilitating the availability of the data collected, and using the most recent techniques for the data processing and interpretation.
