Arsenic in Aquatic Environments

Studies on arsenic removal (arsenite and arsenate) by mineral and organo-mineral complexes from contaminated solutions, affected by pH, presence of competing ligands (at different molar ratios and sequence of addition), adsorbents nature, etc.

Arsenic in Soil System

Studies on the mobility of arsenic (arsenite and arsenate) in soil and its adsorption on soil organic and inorganic compounds (clays, Al and Fe oxides), etc.

Arsenic in Soil-Plant System

Studies on phyto-availability of arsenic  (arsenite ed arsenate) in soil, its uptake by edible plants grown on naturally As-contaminted soils or irrigated with As-contaminated waters, affected by either arbuscular mycorrhyzal fungi, phosphorus or compost supply.

Bioremediation of Contaminated Sites

This topic was studied by our research group for long time and deals with different approches to bioremediate soil and  waste water.  The bioremediation processes are based on biotic   catalysts such as enzymes responsible for the oxidative process of pollutants or the direct use of microorganisms able to metabolize pollutant molecules.

Degradation of Aircraft Deicing Fluids in Oslo Airport

The research dealed with the fate of aircraft deicing fluids in Oslo Airport and the effect on biochemical and biological properties on soil profiles (EU project-Environment “Soil Contamination: Advanced integrated characterisation and time-lapse Monitoring (SoilCAM)” (2008-2012).

Heavy Metals in Soil and Waters

Studies on the mobility of heavy metals in soil and their adsorption on soil organic and inorganic compounds (clays, Al and Fe oxides), etc.   Studies on heavy metals removal by mineral or organo-mineral complexes from contaminated solutions, in single or multiple systems, affected by pH, sequence of addition of the metals and their molar ratio, adsorbents nature, etc.

Monitoring of Soil Quality

Chemical methodologies for assessment of soil and sediment contamination and feasability to reclamation. Aims of  investigations are:
- to assess the mobility, bioavailability and geochemical forms of potentially toxic metals in soils from agricultural, urban and industrial areas;
- to assess the potential of a plant-based methodology of reclamation of polluted soils and the plant induced effects on metal bioavailability and soil properties.
