Abstract: To understand pollution level and possible sources ofatmospheric
fine particulates in rural areas of southern Jiangsu Province of China, samples
of PM_{2.5} were collected and analyzed in Xueyan Town and
Taihu Lake Station over three seasons from July 2002 to January 2003. The mass
concentrations of PM_{2.5} and 14 principal component
elements were obtained. The results showed that pollution of
PM_{2.5} was serious and the concentration levels of S, Zn,
Pb and As were similar to city. There are different seasonal distribution laws
of pollutant elements in PM_{2.5} between two sampling
sites, probably due to contribution of local sources, medium or long distance
transportation of fine particulates and complicated meteorological conditions.
The enrichment levels of S, Zn, Pb, As, K were high, reflecting the influence
of anthropogenic activities. Particularly enrichment level of S was much higher
in summer, which was probably related to meteorological condition. The result
of principal components analysis showed major sources of
PM_{2.5} included crustal resuspension, coal burning, metal
processing industry or waste incineration, vehicular emission, which suggests
anthropogenic activities is of important influence on
PM_{2.5} in rural areas of southem Jiangsu Province.
