Title: NARSTO_SOS_SC_UPSTATE PM2.5 Composition Data
Description:
Abstract:
The purpose of this study is to determine experimentally the
concentration and chemical composition of fine particulate
matter(PM2.5, particles with a diameter less than 2.5 um) in South
Carolina. During the course of this study,data were collected during
July of 2001 and then again during January of 2002 in order to
elucidate the seasonal variability of the aerosol. Samples, which were
collected at a rural location in South Carolina, begun and finished at
midnight in order to associate each sampling event with a calendar
day. In all, 40 samples per month have been collected (including
blanks). The collection of PM2.5 samples on Teflon filters was carried
out using a cyclone-based system. Ion chromatography analysis for
anions and cations was performed, as well as x-ray fluorescence (XRF)
analysis for crustal metals. PM2.5 samples on quartz filters also
were collected in order to determine the organic and elemental carbon
(EC/OC) particle concentration.
The average concentration for PM2.5 during July of 2001 was 20.85
mg/m3. The major components of the aerosol were organic compounds
(38.5%) and sulfates (34.7%). During January of 2002, the average
concentration for PM2.5 was 9.4 mg/m3. Again, the major components of
the aerosol were organic compounds (64.1%) and sulfates (21.9%).
