STUDY ON ELEMENTAL CONCENTRATION IN AIR PARTICULATE MATTER BY ICP-MS

This study conducted air particulate matter sampling to measure the total suspended particulate (TSP), PM 10 (particles10 μmm in aerodynamic diameter) and PM 2 5 (particles2 5 μmm in aerodynamic diameter) mass concentration at Tongan district in Xiamen. One hundred and nineteen samples were obtained to measure the mass concentrations of TSP, PM 10 and PM 2 5 during 15 April to 6 June 2002. According to these results, the TSP, PM 10 and PM 2 5 mass concentrations varied from 53 μg·m -3 (from 26 to 105 μg·m -3 ), 48 μg·m -3 (from 23 to 74 μg·m -3 ) and 41 μg·m -3 (from 18 to 62 μg·m -3 ), respectively. 18 elemental concentrations were determined by ICP MS, most elemental profiles were lower than previous studies. However, high levels of Pb and Zn indicate some pollutants existed in air particulate matter.
