摘要:近年國內食安問題為國人所重視,而農安為食安根本,監察院目前對於國內農業生產環境管理現況也積極進行多項專案調查,足見此議題之重要性。農業生產環境受國土規劃所造成之城鄉發展失衡,面臨之污染風險迥異,相對管理策略與資源投入亦應根據分區分級進行彈性調整。此外,台灣農業生產環境以重金屬為主要污染物,其流佈需經由適當之傳輸模式加以評估,以作為總量管制的基礎。爰此,本計畫首先將延續去年水土分級指標,考量納入有機污染物資訊以完善農業生產環境分級標準,並召開專家諮詢會議評估新分級標準之適當性。此外,本計畫將持續繪製全台農田水利會灌區內農業生產環境分級地圖範圍達37.3萬公頃。隨後針對上述各級農業生產環境制定相對應管理策略,並召開專家諮詢會議探討管理策略之適宜性。另外將探討並公佈農業生產環境風險區與警戒區所帶來之影響與衝擊。本計畫採用兩項模擬軟體,結合灌溉渠道之水文水理資訊,推估重金屬污染物於水體中之流佈。同時,辦理今年度隱患區(台中、彰化地區)之補充採樣調查,以驗證傳輸模式之合理性。為實際掌握渠道水體確切重金屬濃度資料,本計畫亦持續開發縮時之離子交換樹脂包,強化對現地污染物捕捉能力,並應用計畫採購之檢測儀器驗證樹脂包所測得之重金屬濃度。最後,蒐整農業生產環境中水體、土壤、作物、產銷等四階段重金屬污染預警相關資料,將結合本總體計畫「農業生產環境安全管理研發計畫」之各項科研試驗與政策研究成果,研擬農業生產環境安全預警流程與方法,並辦理專家諮詢會議探討此預警架構之妥適性。為了達到維護農業生產環境安全之目標,本計畫將整合上述農業土水資源分級管理策略、污染物傳輸模式,建立整合性之農業生產環境預警系統。
Abstract: Food safety draws highly attentions from people in recent years and agricultural safety is the root thereof. Now, The Control Yuan of R.O.C. intensively performs a number of investigation projects related to the current situation of domestic agricultural production environment management, this action stresses the importance of the food safety issue. Due to imbalanced developments between city and county caused by national spatial planning and, pollution risks encountered by different agricultural production environments varies largely so that relative management strategies and resources input should be adjusted elastically according to a classification of water and soil. Furthermore, heavy metals are main pollutants in the agricultural production environment in Taiwan and the spread thereof should be assessed through suitable transfer mode to be used as the foundation of total quantity controls. As a result, the project keeps on the result of indicators of classification of water and soil last year and incorporates information of organic pollutants into the indicators to enhance the classified standards of an agricultural production environment. Also, an expert consultative council will be launched to evaluate the adequacy of new classified standards. Moreover, the project keeps making classified map of agricultural production environment within irrigation areas of irrigation associations in Taiwan up to 373,000 hectares. Followed by formulating different management strategies for the aforementioned agricultural production environment in each classification of water and soil and launching expert consultative council for discussing the adequacy of the management strategies. Next, the project adopts two transfer mode software and incorporates hydrographic information of irrigation ditches to estimate the spread of heavy metals pollutants in water. Meanwhile, an investigation by supplementary sampling in the hidden risk area, Taichung and Changhua, this year will be launched to verify the adequacy of transfer mode. For practically controlling concentrations of heavy metals in water, the project continues developing time-lapse ion-exchange resin capsules and strengthens the ability to capture in-situ pollutants. Moreover, detection equipment purchased in this project will be applied to verify the concentrations of heavy metals obtained from the resin capsules. Finally, literatures relevant to the early-warning of heavy metal pollutants in agricultural production environment at four stages (water, soil, crops, and production market) will be collected and incorporated into each scientific research and policy research within entire project "Development Project of Safety Management in Agricultural Production Environment" to develop early-warning flow and method for agricultural production environment safety. Furthermore, an expert consultative council will be launched to assess the adequacy of the frame of the early-warning system. To reach the goal of maintaining the safety of agricultural production environment, the project will combine the aforementioned management strategies of classified agricultural water and soil resources and transfer mode of pollutants to establish an integrated early-warning system of the agricultural production environment.
