Abstract

A sampling station was set up in the suburb of southwest Beijing. PM_2.5 (diameter <2.5 μm, fine) and PM₁₀ (diameter <10 μm, coarse) airborne particulate matter (APM) were collected by a Gent stacked filter unit sampler. The samples, collected during spring and summer of 2005, were analyzed by k₀ instrument neutron activation analysis (INAA) using the software of ADVNAA. The average volume concentrations of PM_2.5 and PM₁₀ APM during spring season are found to be 41.43 μg/m³ and 140.82 μg/m³, respectively, while those during summer season are 50.63 μg/m³ and 119.10 μg/m³, respectively. The major pollution elements and their variations with season and special weather condition are primarily identified by enrichment factor analysis.
