Method for investigating the hygroscopic and optical character of organic carbon in atmospheric aerosols
… absorption of the water-soluble organic carbon (WSOC) component of the aerosol. This method is applied to organic aerosol generated by burning and pyrolyzing biomass. The IE-HPLC method can fractionate WSOC, generated from a range of combustion conditions, into several distinct groups using …

Spatial trends in surface-based carbonaceous aerosol measurements during DISCOVER-AQ in Houston, TX.
… carbon (EC) and water-soluble organic carbon (WSOC) ambient concentrations. On average, peak concentrations of OC, EC and WSOC occurred during the last week of the campaign, which coincided with peak ozone on September 25, 2013. Determining carbonaceous aerosol concentrations is fundamental in …

Inorganic and organic speciation of atmospheric aerosols by ion chromatography and aerosol chemical mass closure
… to the water-soluble organic carbon (WSOC); (3) to perform quality control of the IC data, e.g., by comparing them with total element data; (4) to examine the sampling artifacts for inorganic and organic species on quartz fibre filters; and (5) to perform aerosol chemical mass closure. …

Characterization and source apportionment of ambient PM2.5 in Atlanta, Georgia: on-road emission, biomass burning and SOA impact
… carbon (OC), water-soluble organic carbon (WSOC), elemental carbon (EC), ionic species, and tens of trace metals. Day-night, seasonal and spatial variations of PM2.5 characterization were also studied. Contributions of PM2.5 major sources were identified quantitatively through the receptor …

Measurement of the cellular oxidative potential and cytotoxicity of ambient pm2.5 – an assessment of toxic pm2.5 chemical components and their sources in the midwest US
… compounds (i.e., water-soluble organic carbon (WSOC)) and metals (Fe and Cu). To further confirm the interaction of metals (Cu, Fe, and Mn) and organic compounds in cytotoxicity, these two components in different concentration ratios were mixed to expose the cells, and the cytotoxicity results …

Auswirkungen atmogener Stickstoffeinträge auf die Kohlenstoff- und Stickstoffdynamik unterschiedlich stark stickstoffbelasteter Waldböden
… vom POC in der Sand-Braunerde zum WSOC und CKCl im Sand-Podsol zu verschieben. 7. Als verfügbare Stickstoffquelle nutzen die Mikroorganismen am Standort Kreinitz den PN, während sich für den Standort Thülsfeld keine eindeutige Stickstofffraktion als Hauptnahrungsquelle ermitteln …

Ambient measurements of chemical and physical properties of organic aerosols: Insights into formation, growth, and heterogeneous chemistry
… resembles secondary organic aerosol (SOA), while WSOC at TF appears to result from mixed sources.</p><p>In Chapter IV, a newly identified formation pathway for nitrous acid (HONO) is presented. HONO is an important precursor to hydroxyl radicals in the troposphere and thus contributes to the …
