中文摘要	本計畫彙整近年稻米檢測資料，篩選稻米砷濃度偏高區域進行環境砷濃度流布探討，調查稻米砷濃度曾偏高區域之鄰近土壤與引灌水源之砷含量，進一步整合自「食品中污染物質及毒素衛生標準」實施以來，國內稻米砷超標農地案例，歸納其環境土壤與地下水砷濃度趨勢，並驗證相關應變程序可行性，作為縣市環保機關會調砷米超標通報事件之因應策略參照。環保署為協助縣市環保機關辦理農地土壤砷濃度達污染管制標準之成因判定，雖已於民國107年3月28日公布土壤砷污染判定及處理原則，然而前述原則自發布以來時常發生無法判定或判定困難等問題，因此本計畫依據國內歷史土壤檢測數據篩選3處樣區，利用調查結果及歷年土壤砷污染判定案例，修正原有土壤砷污染判定流程。長期引灌富砷地下水致使農地土壤砷逐漸累積，在我國主要農業區與地下水砷潛勢範圍重疊度高的條件下，倘若貿然限制地下水的使用對現今農地農地活化政策產生衝突，為此本計畫期建立農地土壤砷預警機制，以利未來縣市主管機關就轄下農地面臨風險之管理作為，同時確保推動示範之管理機制符合民意與實務需求，於本計畫辦理3場次培力學堂、1場專諮會與2場座談會，收集實務運用之回饋意見供環保署參考。

摘要	This project has aggregated rice testing data from Taiwan Agriculture Chemicals and Toxic Substances Research Institute(TACTRI), Council of Agriculture of Executive Yuan, screened and discussed Arsenic(As) environmental distribution in areas where high As concentration was found in rice outside the potential area of high As concentration in groundwater in order to clarify heavy metals’ concentrations such as As in soils and irrigating water in the adjacent area where high As concentration in rice was observed. Also, to provide a reporting strategy of As in rice incidents as a reference to local environmental protection bureaus(EPBs), this project has integrated historical domestic cases of inorganic As concentration in rice exceeded the limit value, summarized As concentration in soils and groundwaters, and verified the response protocol. To reduce the cost of investigation, complete As exceedance determination efficiently through initial evaluation by local EPBs, and solve the difficulty and issue where As concentration exceedance in agriculture soils was occurred naturally, this project has completed a revised version of “the process for determining soil arsenic pollution” and amended an initial evaluation method by screening 3 sample areas over 28,880 historical domestic soil testing data, completing an investigation, and integrating historical As contamination in soil cases. Long-term As-rich irrigating water from groundwater source discharged into farmlands may cause As accumulation in farmlands and increase the probability of farmland soil exceeding the standard. Moreover, the potential areas of high As in groundwater and main agricultural areas are highly overlapped, the conflicts between current farmland revitalization policy and sustainable use policy may occur if stricter groundwater use regulation was implemented. This project has established early warning mechanisms for As in farmland soil with long-term continuous monitoring, and developed soils, groundwaters, and crops safety management measures to facilitate local EPBs to evaluate agriculture land management and the necessity of remediation. Meanwhile, to demonstrate its management mechanism in both public opinion and practical needs, public participation was introduced in this investigation process by collecting the opinions of stakeholders in 3 meetings involving a total of 130 participant.
