摘要:
The carbonaceous aerosol concentrations in coarse
particle (PM10: Dp≤10 μm, particulate matter with an aerodynamic
diameter less than 10 μm), fine particle (PM2.5: Dp≤
2.5 μm), and ultrafine particle (PM0.133: Dp≤0.133 μm) carbon
fractions in a rural area were investigated during haze
events in northwestern China. The results indicated that
PM2.5 contributed a large fraction in PM10. OC (organic carbon)
accounted for 33, 41, and 62 % of PM10, PM2.5, and
PM0.133, and those were 2, 2.4, and 0.4 % for EC (elemental
carbon) in a rural area, respectively. OC3 was more abundant
than other organic carbon fractions in three PMs, and char
dominated EC in PM10 and PM2.5 while soot dominated EC
in PM0.133. The present study inferred that K+
, OP, and OC3
are good biomass burning tracers for rural PM10 and PM2.5,
but not for PM0.133 during haze pollution. Our results suggest
that biomass burning is likely to be an important contributor to
rural PMs in northwestern China. It is necessary to establish
biomass burning control policies for the mitigation of severe
haze pollution in a rural area.
