Temporal and spatial characteristics of atmospheric carbonyl compounds in Kaohsiung Area
No full textThe concentrations of atmospheric carbonyls were studied by the LpDNPH-Cartridge and the microcomputer air sampling device at Nan-Chie \ue3Hsiung-Kong\ue3Ren-Wu and Lin-Yuan sites. Factor analysis was also used to determine the source apportionment in the Kaoshiung area.
The results showed that the highest concentrations of carbonyls was acetaldehyde (27.83, 28.91, 11.46 and 10.06 \uce\ubcg/m3) at four sites, followed by formaldehyde (5.03, 6.92, 7.88 and 6.59 \uce\ubcg/m3), respectively.
The highest concentration of total carbonyls at Nan-Chie and Hsiung-Kong was 65.42 \uce\ubcg/m3 and 85.09 \uce\ubcg/m3 in summer, the lowest concentration was 25.06 \uce\ubcg/m3 and 37.12 \uce\ubcg/m3 in winter, relatively, the highest concentration of total carbonyls at Ren-Wu and Lin-Yuan was 49.94 \uce\ubcg/m3 and 55.24 \uce\ubcg/m3 in winter, the lowest concentration was 24.48 \uce\ubcg/m3 and 11.78 \uce\ubcg/m3 in autumn. Additionally, peak rush hours of the traffics, either in the morning or at night, would result in increased concentration of Carbonyls.
The results of factor analysis showed that the principle sources at Nan-Chie were traffic exhausts (diesel and gasoline vehicle) and stationary sources (metal assembly, waste treatment, pulp and restaurant). The principle sources at Hsiung-Kong were traffic exhausts (diesel, and gasoline vehicle), stationary sources (leather, chemical process and restaurant). The main sources at Ren-Wu were traffic exhausts (gasoline vehicle) and stationary sources (metal assembly, chemical process and restaurant). The main sources at Lin-Yuan were traffic exhausts (diesel vehicle) and stationary sources (metal assembly, leather, steel production and restaurant)
