Abstract. A systematic study of black carbon (BC) vertical profiles measured at high-resolution over three Italian basin valleys (Terni Valley, Po Valley and Passiria Valley) is presented. BC are scarcely available in literature. The campaign lasted 45 days resulted 120 profiles. Besides the mass concentration, measurements along also included aerosol size distributions optical particle counter range, chemical analysis filter samples a full set meteorological parameters. Using collected...
Volatile organic compounds (VOCs) released into the atmosphere by natural and anthropogenic sources play a key role in atmospheric processes. They can react with oxidants leading to secondary aerosols tropospheric ozone, effects on air pollution, human health climate.The Po Valley, located North of Italy is densely populated area influenced intense agricultural, industrial urban-related activities, suffering among worst pollution Europe. Although efforts aimed at characterizing chemical...
Light-absorbing aerosols heat the atmosphere; an accurate quantification of their absorption coefficient is mandatory. However, standard reference instruments (CAPS, MAAP, PAX, PTAAM) are not always available at each measuring site around world. By integrating all previous published studies concerning Aethalometers, AE33 filter loading parameter, provided by dual-spot algorithm, were used to determine multiple scattering enhancement factor from Aethalometer itself (hereinafter CAE) on yearly...
The energy demands of data centers (DCs) worldwide are rapidly increasing, as their environmental and economic costs. This paper presents a study conducted at Sannazzaro de' Burgondi (Po Valley), Italy, specifically aimed optimizing the operating conditions DC designed for Italian Oil Gas Company (Eni) (5200 m(2) Information Technology installed, 30 MW) based on direct free cooling (DFC) system. aim was to save largest possible quantity energy, while same time preventing aerosol corrosion....
Climate and pollution can lead to materials weathering. In this study, an innovative method is employed evaluate the hazard for heritage stone substrates induced by synergic effect of particulate matter (PM) climate. respect, two indicators were determined: time wetness number dissolution crystallization cycles. The computed coupling experimental measurements PM deliquescence relative humidity with climatic data. For first time, these estimated based on hygroscopic properties, considering...
Regarding secondary aerosols, in addition to the significant contribution of anthropogenic gases such as NO x and SO 2 , atmospheric ammonia (NH 3 ) plays a crucial role primary basic gaseous species capable neutralizing acidic compounds. This acid–base reaction is responsible for formation ammonium nitrate 4 ), constituting up 60% PM 10 within Po River basin Italy. Ion chromatographic analyses performed on offline samples indicate that this inorganic exhibits minimal concentration...
The effects of hygroscopic atmospheric particles are investigated in relation to the corrosion tin. Surface insulation resistance test boards were directly contaminated both with ambient sampled field at Milan, Italy, and pure saline generated laboratory. An innovative particle deposition device was used uniformly coat circular spots on board surfaces. Deliquescence crystallization water-soluble compounds detected by observing impedance response varying relative humidity (RH) conditions a...
Abstract. This study presents the first measured high resolution vertical profiles of black carbon and calculation aerosol radiative forcing atmospheric heating rates in lower troposphere, over Italy Europe. The is based on carbon, number size distribution chemical composition three Italian basin valleys (Po Valley, Terni Valley Passiria Valley) by means a tethered balloon equipped with micro-Aethalometer, an optical particle counter (OPC), cascade impactor meteorological station....
It is a matter of fact that exposure to persistently high concentrations atmospheric particulate (PM) leads respiratory, cardiovascular, and brain dementia diseases[1]. Establishing direct link between the chemical composition PM its detrimental health effects could potentially inform policies act on sources specific harmful compounds. Unfortunately, composed thousands organic compounds, for most them, their sources, molecular structures, fates are unknown[2]. Significant progress in...
The role of the elemental carbon (EC), in synergy with hygroscopic ionic species, was investigated to study formation electrical bridging phenomena once aerosol deliquescence is achieved. Ambient samples were collected on hydrophobic surfaces urban and rural sites Northern Italy; their conductance measured an Aerosol Exposure Chamber (AEC) while varying relative humidity. An electric signal detected 64% values (11.20 ± 7.43 μS) above failure threshold (1 printed circuit boards. content...
