廢水處理廠 (WWTP) 排放的都市污水被認為是環境中奈米塑膠 (NPs) 和污水有機物 (dEfOM) 的主要來源。本研究模擬NPs對 dEfOM 在污水處理廠至海洋的水體特性變化下聚集行為和能力以及表面粒度之影響。模擬數據指出在高鹽度條件下NPs與有機物較容易團聚成微凝膠(microgels),其機制可能是由二價離子架橋和材料間疏水相互作用的協同效應所驅動的。值得注意的是,當NPs摻入微凝膠中會降低表面粒度,這可能會影響環境中microgels的沉降速度以及微生物附著之能力。

多氟烷基物質 (PFASs) 的運輸和最終歸宿通常被認為受水、懸浮顆粒物 (SPM) 和沈積物之間分配行為的影響。 本研究首次調查了淡水河PFAS 在淡水河-海系統中的水、SPM 和沈積物中的分佈。值得注意的是,SPM 上的 PFASs 與透明胞外聚合物顆粒 (TEP) 含量之間存在正相關關係,這提供了 TEP 可能在 SPM 上積累和集中更多 PFAS 的第一個證據。

本研究室最新研究「海洋塑膠雪花在微型塑膠通過氣泡破裂從水相轉移到大氣作用的新見解」已發表於國際頂尖期刊 Water Research。微型塑膠(MPs)在海洋環境中普遍存在,引起了人們對其對生態系統不利影響的擔憂。瞭解 MPs的傳輸機制對評估其宿命、通量和生態風險至關重要。我們的結果證實 MPs 在海氣相之間轉移的步驟。這項工作為海洋塑料凝膠在決定 MPs 宿命和運輸中的作用提供了獨特的見解。
Our paper with the title “New insights into the role of marine plastic-gels in microplastic transfer from water to the atmosphere via bubble bursting” has been accepted for publication in “Water Research”.
The pervasiveness of microplastics (MPs) in global oceans is raising concerns about their adverse impacts on ecosystems. Our results suggested three steps for MP transfer between air–sea phases. Collectively, this work offers unique insights into the role of marine plastic-gels in determining MP fate and transport, especially at air–sea interfaces.

2) Aggregation and sedimentation of gel-like materials and their environmental implications;
3) Aquatic gel interactions with pollutants, including changing fate, partitioning, toxicity, mobility, etc.;
4) Novel measurement and observation technologies for the properties of aquatic gels;
5) Effect of gel-like substances on surface corrosion and biofouling/biofilm formation;
6) Studies on the role of gels in air–water interfacial physics and chemistry;

本研究室最新研究「“純淨的”黑潮水中的海洋塑膠微粒」已發表於國際頂尖期刊 Marine Pollution Bulletin。該研究是文獻中第一次分析台灣貢獻多少塑膠微粒至黑潮環境。該地區的塑膠微粒(MPs)濃度從 N.D. - 0.15 items/m3。大多數 MP 是聚丙烯、聚乙烯、聚乙烯和對苯二甲酸酯。此外,我們在沿海地區附近發現了 MP 熱點。且在黑潮中亦發現了MP的熱點,該數據表明河流和當地洋流可能可將台灣釋出之MP傳輸或注入北太平洋環流。
Our paper with the title “Marine microplastics in the surface waters of “pristine” Kuroshio” has been accepted for publication in “Marine Pollution Bulletin”.
Microplastics (MPs) are ubiquitous in oceans. Their transboundary transport and fate have aroused global attention. Taiwan is located close to the western boundary current-Kuroshio, is an excellent location to study of MP mobility in the global current and Pacific Garbage Patch. This study is the first investigation to understand the microplastic contamination from Taiwan to the Kuroshio. MP concentrations in the area varied from N.D. to 0.15 items m−3, with an average concentration of 0.05 ± 0.03 items m−3. The majority of MPs were polypropylene, polyethylene, polyethylene and terephthalate. We found two MP hotspots near the coastal zone. One additional hotspot was also identified in the “pristine” Kuroshio suggesting rivers and local currents may play critical roles in transporting or injecting MPs from Taiwan into the North Pacific Gyre.

Our paper with the title “Marine Gel Interactions with Hydrophilic and Hydrophobic Pollutants” has been accepted for publication in “Gel” .
Microgels play critical roles in a variety of processes in the ocean, including element cycling, particle interactions, microbial ecology, food web dynamics, air–sea exchange, and pollutant distribution and transport. Exopolymeric substances (EPS) from various marine microbes are one of the major sources for marine microgels. This review on marine gels focuses on the discussion of the interactions between gel-forming EPS and pollutants, such as oil and other hydrophobic pollutants, nanoparticles, and metal ions.

本研究室與國立清華大學、美國加州大學 (Merced) 合作研究之「利用磁性鑷子平台測量在不同表面上胞外聚合物之粘性」已發表於頂尖期刊 Science of The Total Environment。粘性是海洋有機顆粒聚集和傳輸的主要影響因子,目前文獻中的預測顆粒聚集模式之粘度皆是粗略估算(無法實際測量),這粗估之粘度數值可能會造成顆粒聚集模式與海洋實際狀況產生較大的誤差。有鑑於此,本研究開發一新穎磁性鑷子直接測量胞外聚合物(EPS)粘性的平台,以增進我們對有機顆粒的聚集和沈降過程的理解,這些過程對於有機碳的聚集/垂直傳輸以及對海洋表面生物膜的形成和微生物定殖至關重要。[ Paper Link ]
