In the present study, source apportionment of the ambient summer and winter time particulate carbonaceous matter (PCM) in aerosol particles (PM1 and PM10) has been conducted for the Norwegian urban and rural background environment. Statistical treatment of data from thermal-optical, 14C and organic tracer analysis using Latin Hypercube Sampling has allowed for quantitative estimates of seven di...

Aged organic aerosol (OA) was measured at a remote coastal site on the island of Crete, Greece during the Finokalia Aerosol Measurement Experiment-2008 (FAME2008), which was part of the EUCAARI intensive campaign of May 2008. The site at Finokalia is influenced by air masses from different source regions, including longrange transport of pollution from continental Europe. A quadrupole aerosol m...

In order to investigate the chemical characteristics of aerosol pollution including PM1 and PM2.5 in Handan, offline sampling campaign was conducted concentrations total water-soluble inorganic ions (TWSI), carbonaceous components (OC EC) were analyzed. The average 88.5 ?g/m3 for 122 PM2.5, corresponding ratios versus on non-pollution, mild-moderate heavy 0.67, 0.70 0.77, respectively. TWSI OC ...

We assess impacts of the 2020 COVID-19 lockdown on ambient air quality in Delhi, building over three years real-time measurements black carbon (BC) and nonrefractory submicrometer aerosol (NR-PM1) composition from Delhi Aerosol Supersite public data regulatory monitoring network. performed source apportionment organic (OA) robust statistical analyses to differentiate lockdown-related baseline s...

As a background sampling site in western Japan, the Kanazawa University Wajima Air Monitoring Station (KUWAMS) continuously observes air pollutants, including PM1, PM2.5, organic carbon (OC) and element (EC). Data for September 2019 to April 2020 were compared with data 2018 2019. The mean concentrations of both PM1 PM2.5 4.10 µg/m3 (47%) 5.82 (33%) lower, respectively Coronavirus Disease (COVI...

Fine particulate matter (PM) is object of particular attention due to its health effects. It currently regulated by adopting PM2.5 as an indicator control anthropogenic combustion emissions. Therefore, it crucial collect aerosol samples representative such sources, without including PM from natural sources. Thus, a clean separation between coarse and fine mode should be set. With this purpose, ...

Submicron aerosols (PM1) have more serious effect on the visibility, air quality, human health and climate change compared to coarse particles (particle size between 2.5 10 ?m). There is practical significance in understanding formation mechanisms sources of these particles. In this study, we conducted real-time measurements composition non-refractory submicron (NR-PM1) Guangzhou from 20 Octobe...

Atmospheric submicron particulate matter (PM1) is one of the most significant pollution components in China. Despite its current popularity in the studies of aerosol chemistry, the characteristics, sources and evolution of atmospheric PM1 species are still poorly understood in China, particularly for the two harvest seasons, namely, the summer wheat harvest and autumn rice harvest. An Aerodyne ...

Although China’s severe air pollution has become a focus in the field of atmospheric chemistry and the mechanisms of urban air pollution there have been researched extensively, few field sampling campaigns have been conducted at remote background sites in China, where air pollution characteristics on a larger scale are highlighted. In this study, an Aerodyne high-resolution time-of-flight aeros...
