Photochemical dissolution of buoyant microplastics to dissolved organic carbon: Rates and microbial impacts

Journal of Hazardous Materials, Journal Year: 2019, Volume and Issue: 383, P. 121065 - 121065

Published: Aug. 26, 2019

Trillions of plastic fragments are afloat at sea, yet they represent only 1–2% the plastics entering ocean annually. The fate missing and its impact on marine life remains largely unknown. To address these unknowns, we irradiated post-consumer microplastics (polyethylene, PE; polypropylene, PP; expanded polystyrene, EPS), standard PE, plastic-fragments collected from surface waters North Pacific Gyre under a solar simulator. We report that simulated sunlight can remove sea surface. Simulated also fragmented, oxidized, altered color polymers. Dissolved organic carbon (DOC) is identified as major byproduct sunlight-driven photodegradation. Rates removal depended upon polymer chemistry with EPS degrading more rapidly than PP, PE being most photo-resistant studied. DOC released photodegraded was readily utilized by bacteria. However, one sample organics or co-leachates inhibited microbial growth. Thus, although may ocean's surface, leachates formed during photodegradation have mixed impacts microbes food webs support.

Functional polymer materials for modern marine biofouling control

Progress in Polymer Science, Journal Year: 2022, Volume and Issue: 127, P. 101516 - 101516

Published: Jan. 29, 2022

Marine biofouling is a well-known massive problem: within the shortest time, ship hulls and other man-made submerged surfaces are inevitably populated by various marine organisms. causes severe economic environmental problems. Thus, effective control on of utmost importance. Since middle 20th century, scientists engineers have developed antifouling coatings mainly based continuous release toxic metal ions accompanying booster biocides to repel or kill organisms approaching surface. However, these caused serious harm non-target ocean. Therefore, development environmentally friendly alternative an urgent need, research in this field growing rapidly. This review includes concise basic theory from biology, chemistry, physics. It provides introduction into formation, as well physicochemical surface properties that can be manipulated achieve control. Furthermore, complete overview currently presented summarized. wettability, self-renewable coatings, containing agents, switchable biomimetic coatings.

Pervasive distribution of polyester fibres in the Arctic Ocean is driven by Atlantic inputs

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Jan. 12, 2021

Abstract Microplastics are increasingly recognized as ubiquitous global contaminants, but questions linger regarding their source, transport and fate. We document the widespread distribution of microplastics in near-surface seawater from 71 stations across European North American Arctic - including Pole. also characterize samples to a depth 1,015 m Beaufort Sea. Particle abundance correlated with longitude, almost three times more particles eastern compared west. Polyester comprised 73% total synthetic fibres, an east-to-west shift infra-red signatures pointing potential weathering fibres away source. Here we suggest that relatively fresh polyester delivered Ocean, via Atlantic Ocean inputs and/or atmospheric South. This raises further about reach textile domestic wastewater, our findings this remote region world.
