title: [Element characteristics and sources of PM2.5 at Mount Dinghu in 2006].
abstract: To study the characteristics and sources of particles in Pearl River Delta Region, samples of PM2.5 were collected by high volume sampler, and elements of the samples were determined by ICP-MS. The results showed that concentrations of Pb, V, Cu, As, Zn and Se were 216.24, 15.40, 60.56, 31.81,432.06 and 8.12 ng x m(-3) respectively, those were in high level. Factor analysis on the chemical composition of PM2.5 showed that fuel combustion, metal-working industry, ash and sea salt were the main sources of PM2.5 in this region.
