Dissolved gaseous mercury (DGM) in the Mediterranean Sea : spatial and temporal trends. Marine Chemistry, ISSN 0304-4203. [Print ed.], 2017, vol. 193, str. 8-19, doi: 10.1016/j.marchem.2017.03.002. [COBISS.SI-ID 30436647] All three papers relate to the study of Hg cycling in the marine environment. The first article describes the seasonal variability and the main parameters that influence the methylation potential of Hg in the coastal sediment of the Gulf of Trieste with low Hg content. The second article deals with the development of a new on-line method for determining MeHg in marine water samples, while the third article describes the distribution of the DGM in the Mediterranean Sea, where the highest concentrations are observed at the bottom of the water column and in the vicinity of volcanic activity areas.

The study was oriented into the characterization of deep CO2 source and the possibility to use stable isotope approach as a tool for volcano emissions. The study helped to define a clearer way to identifying/understanding the physico-chemical interactions occurring between deep CO2 deriving from magma degassing inside Mt. Etna feeder conduit and the shallow environment of the volcano, together with the type of temporal variations that take place as a consequence of the dynamics of magma release and transport to the surface through the volcano flanks.

The article describes the link between Hg cycling and its speciates and carbon cycling in the sediment pore waters of the shallow Grade Lagoon. The results suggest that elevated carbon concentrations stimulate the formation of MeHg.
