Texto completoThe aim of this study is to provide a description of the chemical composition of PM2.5 and secondary inorganic component focusing on the formation processes and diffusion in relation to environmental conditions and long-range transport processes. Venice-Mestre area is characterized by several emission sources: industrial zone of Porto Marghera; shipping traffic; Marco Polo airport and trafficked road network. The main goals are: the characterization of the inorganic fraction of PM2.5 in the Venice area (both primary and secondary); the study of the composition of PM2.5 in relation to major inorganic ions and elements, evaluating the seasonality and the relationship with the environmental conditions; the identification of sources and /or particulate formation processes.

Texto completoThe objective of this PhD thesis is the study of mercury and the assessment of its behavior in the different environmental matrices investigated. The doctoral thesis consists of: • a first introductory part, where the main characteristics of mercury and its environmental importance are described. • a second part, where the abstracts of the published papers (in indexed journals) or in the submission phase are presented. The extended works, attached in the appendix, were carried out during the three-year period of the doctoral school, from November 2017 to November 2020. • The first work, (in the submission phase), aims to understand the behavior of Hg in ambient air at a high-altitude station in the Eastern Alps, through the Hg analysis on a monthly, seasonal, and daily basis variations. Ancillary variables (ozone and meteorological parameters) were used for the study of atmospheric Hg, and the analysis of the back-trajectories of the air masses and the planetary boundary layer (PBL) with the aim of identifying potential emission sources. • The second publication shows the investigation of total mercury concentrations in Italian bottled waters, using a very sensitive analytical method, and the possible relationships between mercury, the chemical-physical parameters of the water and the lithology of the aquifer. Furthermore, the determination of Hg levels on a large number of samples can allow us to estimate the intake of mercury from natural mineral waters for different groups of the population. • The overall objective of the third study is the comparison of the inorganic content of water intended for human consumption (drinking water) and natural mineral waters (bottled water) collected in a region of Southern Italy (Calabria). This comparison was made using compositional data analysis (CoDA) and a new graphical-numerical approach. Among the 29 selected parameters, the Hg content was also examined. The comparison of total mercury concentrations between bottled waters and tap waters highlighted differences in the Hg levels of the two typologies of water attributable to the different origins and their management. • The fourth publication aims to understand the behavior of Hg in the snow on the Antarctic plateau through the analysis of data relating to three surface snow sampling campaigns during three austral summers. The study demonstrates how weather conditions can affect mercury deposition processes and its relative abundance in the surface layers of snow.

Texto completoThe aim of this thesis is to present the development of a methodology for the analysis of the pollutants distribution within the plume of a chimney. The study, after a general presentation of the atmosphere, its composition and its interaction with the effluent from a stack, proposes the use of remote sensing methods, which measures and remotely can provide information about the composition of a plume. In this context the DOAS (Differential Optical Absorption Spectroscopy) methodology, described in the second chapter, turns out to be very suitable for the type of investigation proposed. The third chapter describes the methodology of reconstruction of the pollutants within the plume and for the calculation of the flows of emission. In this chapter will be also presented the experimental apparatus used for carrying out the measures. Finally we present the results of this method applied to the cruise ships, the chimney of an incinerator, the chimney of a thermal power plant and finally over large areas, such as the harbor. In the conclusions we will list the advantages and disadvantages of the application of this methodology. This study was born in Venice, to detect the contribution of gaseous emissions from large cruise ships total pollution in the area.
