計畫中文摘要	電子廢棄物回收設施對於處理過時電子設備的處置至關重要，但其可能導致有機磷酸酯（OPEs）對土壤的污染；近年來科技產業日益發達，而伴隨而來的電子廢棄物（e-waste）所致之環境污染已成為一個關鍵問題，迫切需要創新和永續的治理策略。 有機磷酸酯（OPEs）通常被用作電子產品中的阻燃劑和增塑劑，當滲入土壤時可能對生態系統和人類健康構成潛在風險，為應對這一環境挑戰，本研究探索了當前先進之微波電漿和管型爐技術，作為降解來自電子廢棄物回收設施土壤中 OPEs 的潛在解決方案。 本實驗建立OPEs分析方法，利用超音波萃取及索式萃取，其標準品回收率皆介於80~120%之間，結果顯示OPEs在電子廢棄物中的濃度含量，高濃度的有TBP(320~334 ng/g)、TPHP(146~148 ng/g)、TBEP(265~284 ng/g)；中濃度的有TCIPP（5.7~7.82 ng/g）、o-TCP(17.2~24.8 ng/g)、 TiPPP(8.57~9.32 ng/g)；其餘的OPEs皆為較低濃度的TEP、TPrP,、TCEP、 TPeP、TDCPP、 EDP、 TEHP、 CDP、 m-TCP、 p-TCP、 BPDP(其濃度範圍皆< 3 ng/g)。
計畫英文摘要	Environmental contamination resulting from electronic waste (e-waste) has emerged as a critical concern in recent years, prompting a need for innovative and sustainable remediation strategies. E-waste recycling facilities, while essential for managing the disposal of obsolete electronic devices, may inadvertently contribute to soil contamination with Organophosphate Esters (OPEs). These OPEs, commonly used as flame retardants and plasticizers in electronic products, pose potential risks to ecosystems and human health when leached into the soil. In response to this environmental challenge, the current research explores the application of advanced technologies—specifically microwave plasma and electric tube furnace methods—as potential solutions for decomposing OPEs in soil from e-waste recycling facilities. The complex matrix of e-waste, consisting of a myriad of electronic components, necessitates a nuanced and effective approach to address the specific challenges posed by OPE contamination. The following exploration delves into the contextualization of the problem, the need for innovative remediation technologies, the objectives of the study, and the overarching significance of the research in advancing sustainable practices in e-waste management. This comprehensive investigation seeks to shed light on the environmental implications of OPE contamination, offer pioneering solutions through cutting-edge technologies, and contribute to the broader discourse on responsible electronic waste disposal. In this project, the concentration levels of various OPEs in e-waste were determined using Soxhlet extraction. The OPEs found at high concentrations were TBP (320~334ng/g),TPHP (146~148ng/g),TBEP (265~284ng/g);at medium concentrations were TCIPP(5.7~7.82ng/g),o-TCP (17.2~24.8ng/g), TiPPP (8.57~9.32 ng/g);The remaining OPEs were found at lower concentrations, including TEP, TPrP , TCEP, TPeP, TDCPP , EDP , TEHP , CDP , m-TCP , p-TCP , BPDP (all with concentrations < 3 ng/g).
