dc.description.abstract | Raman microspectroscopy and thermo-optical-transmittance (TOT) method were used to
study airborne ambient soot collected at the suburban air monitoring station in southern Poland
during the residential heating (January-February) and non-heating (June–July) seasons of 2017.
Carbonaceous material constituted on average 47.2 wt.% of PM2.5 during the heating season and
26.9 wt.% in the non-heating season. Average concentrations of OC (37.5 11.0 g/m3) and EC
(5.3 1.1 g/m3) during the heating season were significantly higher than those in the non-heating
season (OC = 2.65 0.78 g/m3, and EC = 0.39 0.18 g/m3). OC was a chief contributor to the
TC mass concentration regardless of the season. All Raman parameters indicated coal combustion
and biomass burning were the predominant sources of soot in the heating season. Diesel soot, which
is structurally less ordered than soot from other sources, was dominant during the non-heating
season. The D1 and G bands area ratio (D1A/GA) was the most sensitive Raman parameter that
discriminated between various soot sources, with D1A/GA > 1 for diesel soot, and less than 1 for soot
from coal and wood burning. Due to high daily variability of both TOT and Raman spectroscopy data,
single-day measurements can be inconclusive regarding the soot source apportionment. Long-time
measurement campaigns are recommended. | pl_PL |
