Suspended particle matter (SPM) data were collected in Kitakyushu area to study on the joint application of dispersion and Chemical Mass Balance (CMB) method to source apportionment of particulate in atmosphere.
Source contributions were identified by CMB method using chemical components of particulate collected by hi-volume air sampler. Dispersion data were classified into source groups which discharges similar components, and these dispersion data were compared with same source groups calculated by CMB method. As to source groups which could not be calculated by dispersion model (secondary particulate, sea salts, etc.), CMB data were added to dispersion data.
By these method, 73% of observed data were identified by calculation, and dispersion results could be compared with CMB results each source groups. Source apportionment estimates from these two models were good affinity in the comparisons of carbonaceous materials, but not in soil dust. And a good agreement was obtained between the observed and calculated concentration. Source contributions estimatedby CMB model (secondary particulate, sea salt etc.) were classified into each block to simulate the present SPM concentration.
Thus calculated SPM concentration isopleth in Kitakyushu area could be described.
