    摘要: 自然環境污染是一種被視為對人類健康有害的情況,這種情況常常暴露於特定地理區域的化學物質,尤其是受人類活動影響的化學物質。長期的地下水質量調查顯示,台灣南部屏東平原地下水的20%明顯受到砷,鎘,鉻,鉛,錳和氮氧化物濃度的測量,超過了建議的最大可接受水攝入量。世界衛生組織。屏東平原除了用於家庭活動的用水外,還有很高的農業活動。為了確定健康風險管理的重要性,努力評估與受污染的飲用水中攝入有害化學物質有關的健康風險。 。為此目的,進行人體健康風險評估的傳統方法可能有限,本研究採用地質統計學克里格法對屏東平原飲用地下水攝取有害化學物質所帶來的健康風險進行空間分析。根據危險指數(HQ)和目標癌症風險(TR)評估健康風險。結果表明,大多數總部超過1的區域位於研究區的西南部。因此,應嚴格避免在這些地方使用地下水飲用。此外,還提供了描繪具有高TR值和高人口密度的區域的地圖,以及顯示所有致癌物質污染物的癌症曲線圖。;Natural environmental contamination is a situation regarded as harmful for human health which are routine expose to chemicals that are present in a particular geographical area, especially as affected by human activity. A long-term groundwater quality survey has revealed that 20% of the groundwater in southern Taiwan’s Pingtung Plain is clearly contaminated with measured As, Cd, Cr, Pb, Mn and NO_3 concentrations in excess of the maximum accepted levels of water ingestion recommended by the World Health Organization. Pingtung Plain has a high agriculture activity in addition of the water use for domestic activities, Efforts to assess the health risk associated with the ingestion of harmful chemicals from the contaminated drinking water need for a particular purpose in order to determine the importance for health risk management. The conventional approach to conducting a human health risk assessment may be limited for this purpose, this study adopts a geostatistical Kriging method to perform a spatial analysis of the health risk associated with ingesting harmful chemicals through drinking groundwater in the Pingtung Plain. The health risk is assessed based on the hazard quotient (HQ) and target cancer risk (TR). The results show that most areas where the HQ exceeds 1 are in the southwestern part of the study area. Thus, the use of groundwater for drinking in these locations should be strictly avoided. A map that delineates areas with high TR values and high population densities is provided in addition a cancer curve diagram to display all carcinogen chemicals contamination.
