Characterization of Metal Species in TSP and PM10 Aerosols in Jiaozuo, China

Aerosol samples for TSP and PM₁₀ were collected in April 2007 at two different sampling locations in Jiaozuo, China. TSP and PM₁₀ were collected by mid-volume samplers and the concentrations of major metal elements were quantified by inductively coupled plasma mass spectrometry (ICP-MS). The ratios of PM₁₀/TSP were 0.72 and 0.76 at the HPU campus and WIST campus, respectively. These results indicated that the concentrations of PM₁₀ contribute the majority of the TSP fraction. The concentrations of anthropogenic species (e.g. As and Se) in TSP and PM₁₀ measured in urban areas were generally higher than those in a rural environment. The high concentrations of As and Se in Jiaozuo City showed a good relation of coal combustion compared with those studied in other cities in China.
