Characterization of major chemical components of fine particulate matter in North Carolina.
This paper presents measurements of daily sampling of fine particulate matter (PM2.5) and its major chemical components at three urban and one rural locations in North Carolina during 2002. At both urban and rural sites, the major insoluble component of PM2.5 is organic matter, and the major soluble components are sulfate (SO4(2-)), ammonium (NH4(+)), and nitrate (NO3(-)). NH4(+) is neutralized...
متن کاملInteractive comment on “Elemental and organic carbon in PM10: a one year measurement campaign within the European Monitoring and Evaluation Programme EMEP” by K. E. Yttri et al
This manuscript deals with the measurement of carbonaceous particulate matter in aerosols collected at 12 rural/background sites and 2 sub-urban sites across Europe, using, mainly, the EMEP measuring network. Taking into account the relative importance of carbonaceous material in continental atmospheric aerosols and the lack of extensive measurements of carbonaceous aerosol characteristics in r...
متن کاملIdentification of Indoor and Outdoor Particulate Concentration and its Chemical Composition in Kathmandu Valley
The indoor and outdoor particulate concentration and its chemical composition in six monitoring stations and selected residential dwellings were studied in May 2010 in Kathmandu valley. The six stations were strategically located to measure the air quality of the valley viz. -urban roadside, urban hospital, urban residential, urban background and valley background. Particulate concentration was...
متن کاملEvaluation of organic carbon, elemental carbon, and water soluble organic carbon concentration in PM2.5 in the ambient air of Sina Hospital district, Tehran, Iran
In the present study, carbon species including organic carbon (OC), elemental carbon (EC), and water-soluble organic carbon (WSOC) concentration in PM2.5 were assessed at an urban site of Tehran, Iran during March to June 2014. The PM2.5 samples were collected using an frmOMNITM Ambient Air Sampler. Thermal gravimetric analysis (TGA) was used to analyze OC and EC. The results showed that PM2.5 ...
متن کاملUrban impacts on regional carbonaceous aerosols: case study in central Texas.
Rural and background sites provide valuable information on the concentration and optical properties of organic, elemental, and water-soluble organic carbon (OC, EC, and WSOC), which are relevant for understanding the climate forcing potential of regional atmospheric aerosols. To quantify climate- and air quality-relevant characteristics of carbonaceous aerosol in the central United States, a re...
