摘要: | 健康風險評估因可將環境污染現況的模擬結果與當地居民的生活情境作結合,進一步了解污染情況對於人類健康的影響,有利於相關評估者,決策管理者的進行相關的剖析及判斷,故近年來已廣泛地做相關的運用。
本研究收集高雄臨海工業區內的一貫作業鋼鐵廠生產過程中所排放代表性的有害空氣污染物-戴奧辛為案例,結合及周遭的居民受體的暴露資訊,納入大氣擴散及多介質擴散方法,量化出在我國環保主管機關所訂定的排放標準是否有保護到居民的健康,並進一步比較在實際排放濃度下居民所受到的實際風險,研究結果健康致癌風險均低於10-6。 另以累積性風險評估的思維,設定於多重污染源下單一污染物種的系統進行分析,除前述一貫作業鋼鐵廠外尚包含背景源,進行多重來源下對於戴奧辛累積性致癌風險綜合探討,研究結果顯示背景源所造成的風險不可忽略。 Human health risk assessment can connect the contaminated environment media with the scenario of human life and estimate the probability of adverse health effect in humans. Recently, this approach has been largely applied in several areas and helps assessors or leaders make the decision. The research is focus on the typical air toxic pollutant – dioxin from the sinter process of the steel plant in Linhi industrial park in Kaohsiung city . I combine the exposure scenario with contaminated environment media which was predicted by the air dispersion model and multiple media model in order to understand whether the emission standard of the dioxin from steel plant is reasonable for the local residents. Furthermore, I also evaluate the human health risk in the real pollutant emission status. The results show the both risk are below 10-6 The research also discuss and investigate the system from multiple source of dioxin ,including sinter process of the steel plant and background concentration by the accumulative health risk analysis . The results show the human health risk from background concentration can’t be ignored. |
