摘要:Organic gases emitted during the flaming phase of residential woodcombustion are characterized individually and by functionality using protontransfer reaction time-of-flight mass spectrometry. The evolution of theorganic gases is monitored during photochemical aging. Primary...

摘要:Organic aerosols (OAs), which consist of thousands of complex compounds emitted from various sources, constitute one of the major components of fine particulate matter. The traditional positive matrix factorization (PMF) method often apportions aerosol mass spectrometer (AMS) org...

摘要:Equivalent black carbon (EBC) measured by amulti-wavelength Aethalometer can be apportioned to traffic and woodburning. The method is based on the differences in the dependence of aerosolabsorption on the wavelength of light used to investigate the sample,parameterized by th...

摘要:Black carbon is a primary aerosol tracer for high-temperaturecombustion emissions and can be used to characterize the time evolution ofits sources. It is correlated with a decrease in public health andcontributes to atmospheric warming. Black carbon measurements are usuallyc...

摘要:A PM2.5-capable aerosol chemical speciation monitor (Q-ACSM) was deployed in urban Nanjing, China, for the first time to measure in situ non-refractory fine particle (NR-PM2.5) composition from 20 October to 19 November 2015, along with parallel measure...

摘要:Secondary organic aerosol (SOA) yields from the photo-oxidation of α -pinene were investigated in smog chamber (SC) experiments at low(23–29 %) and high (60–69 %) relative humidity (RH), variousNO x ∕ VOC ratios (0.04–3.8) and with different aerosol seedchem...

摘要:Secondary organic aerosol (SOA) is an important contributor to fine particulate matter (PM) mass in polluted regions, and its modeling remains poorly constrained. A box model is developed that uses recently published literature parameterizations and data sets to better const...

摘要:The present study offers the first chemical characterization of the submicron (PM1) fraction in western Africa at a high time resolution, thanks to collocated measurements of nonrefractory (NR) species with an Aerosol Chemical Speciation Monitor (ACSM), black carb...

摘要:We investigated the seasonal trends of OA sources affecting the air quality of Marseille (France), which is the largest harbor of the Mediterranean Sea. This was achieved by measurements of nebulized filter extracts using an aerosol mass spectrometer (offline-AMS). In total ...

摘要:Water-soluble organic carbon (WSOC) is a large fraction of organic aerosols (OA) globally and has significant impacts on climate and human health. The sources of WSOC remain very uncertain in polluted regions. Here we present a quantitative source apportionment of WSOC, isol...
