摘要：Suspended particulate matter (SPM) levels in air samples collected with a high-volume air sampler from the Kobe area in Japan were measured. Furthermore, the evaluation of the source apportionment to SPM was investigated by the chemical mass balance (CMB) method based on nine elements, i.e., Ca, K, Na, Fe, Mn, Al, Ni, Zn and V, as an index element. The sum of the percent contributions to SPM from six main sources (soil, marine, fuel oil combustion, iron-and-steel industry, refuse incineration, cement particles) was calculated to be about 25%. Among these sources, fuel oil combustion showed the largest contribution.
