The main goal of this research proposal is to provide new insights on the molecular and elemental composition of water soluble organic matter (WSOM) in fine atmospheric aerosols collected in two urban areas with different pollution levels at the West Coast of Portugal. This proposal will also address the non-water soluble organic component, in order to assess the contribution of different groups of organic compounds to the aerosol organic material. The original contribution of this research will derive from the application of a state-of-the-art, well-established analytical methodology that couples an isolation procedure with the investigation of C-H bond connectivities. In order to accomplish a comprehensive characterization of the chemical nature of urban fine air particles, their inorganic chemical composition will also be assessed. The ORGANOSOL strategy will contribute to a comprehensive understanding of the occurrence, origin and identity of particulate organic matter, focusing on their seasonal cycles for different scenarios of emission sources. The establishment of a comprehensive urban organic aerosol data set, lacking until now, will provide scientifically sound and global conclusions regarding the structure-origin relationships that govern the breathable organic matter present in urban air particles.
In order to achieve the proposed objectives, the ORGANOSOL project will involve one Associated Laboratory and one Research Unity of University of Aveiro (UA): CESAM (Centre for Environmental and Marine Studies) and GeoBioTec (GeoBioSciences, GeoTechnologies and GeoEngineering), engaging researchers from the Department of Chemistry and Department of Geosciences. A researcher from the University of Vigo (Spain) will also participate in the project. Additionally, two researchers, one from the Organic Chemistry, Natural and Agro-Food Products Research Unit (Department of Chemistry, UA) and the other from CESAM & Department of Chemistry (UA), will also participate as scientific consultants for this research project. The multidisciplinary team combines expertise on structural characterization of complex organic matrices and metal pollution in atmospheric aerosols, soil, and water samples; mineralogical, isotopic and geochemical characterisation of sediments and clays; development of advanced bio-analysis procedures based on mass spectrometry techniques for environmental applications; and the use of advanced spectroscopic techniques in the characterization of several types of organic compounds.
