計畫中文摘要	鑑於偷排廢水事件含有不定時、延時短、污染濃度高且地點廣泛等特性，故偷排行為難以防範。連續監測成本高昂，因此違法行為始終難以全面掌控。本研究利用樹脂離子交換為基材做成重金屬監測包(稱之為「樹脂縮時記錄膠囊」)，大量將其投放於監測之區域，一段時間後收回監測包測定所吸附之重金屬，汙染源的分布特性即被有效掌握，輔以環境指紋辨識方法之科學證據，污染行為人無所遁形。本計畫研發「樹脂縮時記錄膠囊」之架構分為實驗室與現地試驗兩個方向進行。實驗室試驗結果顯示陽離子交換樹脂與水體接觸的通量越大，其吸附重金屬的效率越好；兩者接觸時間達30分鐘時，陽離子交換樹脂對重金屬的吸附效率可達40%以上；在離子交換樹脂之交換容量未達飽和的情況下，重金屬濃度的高低對離子交換樹脂吸附效率的多寡並無顯著差異。針對現地試驗部分，「樹脂縮時記錄膠囊」投放在彰化縣東西二、三圳灌溉區域，涵蓋面積8.8平方公里。監測時間最長達21天，期間共回收404個陽離子樹脂膠囊(回收率89.2%)與28個陰離子樹脂膠囊(回收率93.9%)。根據監測膠囊回收數據顯示，背景元素監測資料特性會隨著時間的累積，水體中因一直存在穩定含量，讓交換形式持續進行，導致背景元素含量有增加的趨勢，以鈣跟鍶為主；另類則是以人為形式(如工廠排放、農業施肥等)加諸於環境水體之中，在特定時間與地點的大量排放，使得「樹脂縮時記錄膠囊」中重金屬元素在特定點位異常增加。本研究透過研發「樹脂縮時記錄膠囊」發展為環境指紋辨識的方法是有效且可行，能夠協助鎖定廢水違法排放之區域，提供政府相關單位能利用有限稽查資源為土壤環境品質監督做最佳把關。
計畫英文摘要	It is difficult to block wastewater illegal discharge behavior owing to the high cost of continuous monitoring, and therefore illegal situation always difficult to fully control. In this study, the heavy metal monitoring package (called "Resin Lapse recording capsule ") made of ion-exchange resin as a substrate was developed. It is an effective monitor device with low cost and rapidly analytic surveillance would be a way to suppress illegal emissions under the limited resource. The goals of this project were divided into the laboratory and the field experiment on two trails direction to carry on. The laboratory experiments to show that the cation exchanges a flux of resin and water body contact affect the adsorb efficiency of heavy metals. The contact time with the heavy metal and cation exchange resin in solution for 30 minutes, cation exchange resin adsorption efficiency of heavy metals can reached 40%. Under the unsaturated condition for the commutation capacity in the ion exchange resin, the level of concentration of heavy metals to the ion exchange resin is no significant difference in the amount of adsorption efficiency. For the field experiment, launch and recovery operations for “Resin Lapse Recording Capsule” had been completed. There were 151 points, covering an area of approximately 8.8 square kilometers. Each site placed three capsules for monitoring time covering 21 days with interval of 7 days. 453 cation resin capsules and 30 anion resin capsules were totally launched in the research areas. After the monitoring, cationic resin capsule recovery was 89.6%; anion resin capsule recovery was 93.9%. Finally, “Resin Lapse Recording Capsule” was carried out to be one of the environmental fingerprint recognitions and also provided the official inspector to identify the specific areas of the illegal pollution emissions under the limited resource condition.
