中文摘要 | 本研究為延續2003年春季於高雄市分析之大氣71種C2-C15碳氫化合物(HC) (Lai, Chen, Ho, & Chou, 2004)中有19種HC被美國環保署列為有害空氣污染物(HAPs)(USEPA, 2003a),並探討其HAPs之健康風險評估與污染源探討。研究結果顯示,楠梓站除Bromoform外, Benzene及含氯HC之Chloroform、Carbon tetrachloride、Vinyl chloride、1,2-Dichloroethane、Trichloroethylene、Tetrachloroethene、Arcylonitrile、1,2-Dichloropropane等之平均致癌風險值介於2.73×10-6-1.04×10-4,都已高過致癌風險標準(10-6)約3-100倍。而小港站19種HC 中之9種致癌性HAPs之平均致癌風險值為2.67×10-6-1.19×10-4 ,亦高過致癌風險標準(10-6)。由統計之變異分析可知,兩測站在累積致癌風險值百分比在前三大致癌HAPs特徵化合物是有差異的,而在非致癌物質HAPs特徵化合物是相似的。 由因素分析可知,HAPs主要為移動源、塑膠相關製程及溶劑使用/逸散等排放,此類污染源亦是高雄市HC排放源百分比之前三大,故值得未來重視與管制。 |
英文摘要 | Data of 19 hydrocarbon species of 71 HC in C2-C15 from previous measurement in Kaohsiung (Lai, Chen, Ho, & Chou, 2004) were defined as Hazardous Air Pollutants (HAPs) by U.S. Environmental Protection Agency (EPA) (USEPA, 2003), the risk assessment was investigated, and the emission source was analyzed. Eight carcinogenic HAPs of mean cancer risk levels except Bromoform exceeded the 1×10-6 risk level by more than 3-100 times, including Benzene, Chloroform, Carbon Tetrachloride, Vinyl chloride, 1,2-Dichloroethane, Trichloroethylene, Tetrachloroethene, Arcylonitrile, and 1,2-Dichloropropane at Nan-Chie site. Nine carcinogenic HAPs of 19 HC mean cancer risk (2.67×10-6-1.19×10-4) also exceeded the 1×10-6 risk level at Hsiung-Kong site. Through the ANOVA analysis, the results showed the top three percent cumulative cancer risk of carcinogenic HAPs characteristic compounds were significant in two sampling stations, but non-carcinogenic HAPs were similar. Factor analyses show that motor vehicle exhaust, plastic product process, and solvents used/fugitive emission are the top three percentage source of HAPs in Kaohsiung city. Theses emission source will be worthy to be paid attention and managed in the future. |
