    摘要: 石化工業在初期扮演著火車頭的角色,但隨著工商業快速發展,大量的汙染物至經由工廠運作排放至大氣中,對人類的健康會產生不良的影響。本研究旨在探討石化工業污染物與社區居民健康影響之關連性,石化工業為大氣環境中揮發性有機物重要排放源,同時也是多環芳香烴的來源之ㄧ。研究發現,暴露於致癌物質的環境中,發生癌症的機率有較高的趨勢;但也有研究認為石化工業區民眾癌症的發生率與一般民眾的發生率無顯著差異。
    Petrochemical industrial acts an important role in the past in Taiwan. As industrial and economic develop rapidly, pollution problems become significant. Air pollutants may be released from operation in plants, thus affect human health. This research studies the relationship between petrochemical pollutions, especially some volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs), and the impact on the health of community residents. Petrochemical industry is an important emission source for atmospheric VOCs, as well as PAHs. Numerous studies have reported outcomes associated with the exposures and health effects. However, results from some studies indicated otherwise.
    The objective of this study is to evaluate the impacts of VOCs and PAHs in the air in the vicinity of a petrochemical plant on community, using basic risk assessment protocol, and expressed as carcinogenic (probability) and noncarcinogenic risk (hazard index) for the residents near the studied area.
    The result of risk assessment is followed, using either the average or highest concentrations scenario, benzene caused the highest carcinogenic risk comparing to other chemical evaluated. The increased total carcinogenic probability for residents in one of the area will be 1×10-5 and 3×10-5, respectively, for either the average or highest concentrations scenario. For the other 3 areas, the risks are all below 1×10-5. The noncarcinogenic risks, expressed as hazard index, for all of areas were below 1.
