Накратко на български
Вторичните органични аерозоли и влиянието на азотните окисли от човешката дейност върху тяхното образуване се анализират чрез лабораторни опити. Тези процеси влияят върху климата, качеството на въздуха и здравето на хората.

Secondary organic Aerosols Production in pre and post-Industrial-like ENvironments : The Impact of biogenic and Anthropogenic emissions on cliMate
The main scope of the SAPIENTIAM (Secondary organic Aerosols Production in pre-and post-Industrial-like ENvironments: The Impact of biogenic and Anthropogenic emissions on climate) project is the identification of innovative mechanisms to describe and investigate the atmospheric composition in pristine environment that are affected by the anthropogenic emissions. The latter, such as nitrogen oxides (NOx, e.g, NO and NO2), are related to human activities in post-industrial scenarios. In detail, the project studies the effect of NOx emissions on Secondary Organic Aerosol (SOA) formation and its chemical compositions. Moreover, we investigate the production and the gas to particle partitioning of organonitrates (ONs, e.g., ΣRO2NO2, and ΣRONO2). Despite the SOA yield as a function of different NOx regimes have been investigated in previous studies, further laboratory experiments are necessary, as the dependency is not univocally determined, to explore the chemistry in chamber conditions that represent more realistically atmospheric concentrations. Particulate matters, which can be emitted both by anthropogenic and biogenic activities, play a significant role in the radiative forcing, i.e. on climate change, via direct and indirect effects; they affect also the atmospheric visibility, and their adverse impact on human health has been demonstrated. At the same time, the ONs represent reservoir species for NO2, and the reaction cycle for their reaction strongly affects the tropospheric ozone (O3) production, which is a greenhouse gas with important oxidative capacity. As a consequence, the study of SOA and ONs production in different NOx regimes has important, different effects in terms of both climate change and air quality, with interdisciplinary impact on society in terms of policy and economy. The SAPIENTIAM project allowed to produce more and innovative knowledge about the role played by the ONs in SOA formation, chemical composition and yield. The gas-to-particle partition of ONs it seems to be really important in new particle formation events and the chamber experiments results have positive feedback in field campaigns data analysis and help to their interpretation.

Цел на проекта
Anthropogenic emissions (i.e. particles and trace gases) are constantly rising since the industrialization inducing wide changes on the climate of the Earth system, on local degradation of air quality and impactAnthropogenic emissions (i.e. particles and trace gases) are constantly rising since the industrialization inducing wide changes on the climate of the Earth system, on local degradation of air quality and impacting human health. The aim of the SAPIENTIAM project is to identify new mechanisms that allow to describe the preindustrial atmospheric status and its change as consequence of the human activities emission related to industrialization. Secondary organic particles are produced in the atmosphere by the reactions of biogenic volatile organic compounds in presence of nitrogen oxides (NOx) and sulfate (SO2). One of the main uncertainties of the role of particles on the changes of climate and air quality, is related to the impact of anthropogenic emissions on their concentrations and properties. In order to define new mechanisms of atmospheric particle formation in pre-industrial and post-industrial conditions, a laboratory experiment will be carried out at the Harvard Environmental Chamber (outgoing phase). In detail, the pristine pre-industrial-like environment’s atmosphere will be simulated in the chamber considering first only the biogenic emissions and, then, adding the contribution of anthropogenic emissions such as NOx and SO2. Recent studies highlighted the important role played by the ocean as potential source of atmospheric particle, but field observations to confirm this hypothesis are quite rare. Another aim of this project is to verify the results obtained by the laboratory experiments in a field campaign in marine environment representing an innovative post-industrial-like site, where the interaction between biogenic and anthropogenic emissions are poorly explored (return phase at the University of Chieti-Pescara, Ud'A)
