PCDD/DFs released to the atmosphere are mainly emitted from anthropogenic activities, including waste incineration, power/energy generation, other high-temperature sources and chemical-industrial sources. Furthermore, polycyclic aromatic hydrocarbons (PAHs) are emitted to the atmosphere from variety sources. Therefore, it is important to evaluate quantitatively the relationship between receptor and sources for effective control about pollutants.
In this study, ambient air samples are collected from 7 highly industrialized area(A∼G) in Korea. Major PAHs sources such as waste incinerator, iron/steel and nonferrous industry, chemical industry were examined and the reference data from other sources such as open burning, crematory, road dust, vehicle exhaust, boiler and briquette was quoted from previous study in Korea.
The first purpose of this study is to evaluate the characteristic of PCDD/DFs, DL-PCBs and PAHs on ambient air of industrial area.
Second purpose is to examine the characteristic of PAHs profile pattern on PAHs sources. PAHs sources were identified with PCA and diagnostic ratio analysis about the ambient air in industrial area and PAHs air emission sources.
Finally, A chemical mass balance model, CMB8.2 was used to apportion the major sources of PAHs detected in ambient air of industrial area. The coefficient of determination R², χ² and percent mass were average 0.99, 1.42 and 83.25%, respectively. Therefore these results of CMB model were confirmed statistically valuable. Modeling results verified that chemical industry and iron/steel and nonferrous industry are major sources of PAHs in this study.
