To improve our understanding and management of marine plastic pollution the ocean, a total budget is needed which quantifies sources sinks, as well inputs removal per unit time. The current state knowledge indicates that coastal zone ocean water column are major locations for pollution, but fate much this must ultimately be deep floor. We reviewed 23 journal articles provide 280 observations deep-sea sediment microplastic concentration across six different off-shelf environments. calculate following mean concentrations particles (number) kg sediment: continental slope 502; submarine canyons 784; fans rise 714; abyssal plains 217; trenches troughs 2782; hills, mountains other floor 165 kg−1. These figures alarming because several exceed one estimate 'safe' levels benthic life (540 kg−1). Monitoring in sediments canyons, environments should priority to ensure efficacy policies actions taken curb at both national global level. 3.05 million tonnes resides acknowledge uncertainties figure. If correct, figure implies (which may contain 90 microplastic) major, transitory sink MP, forming suspended, cloud. In addition particle concentrations, further measurements size mass advance development balance budgets pollution.

Distribution of microplastics in bathyal- to hadal-depth sediments and transport process along the deep-sea canyon and the Kuroshio Extension in the Northwest Pacific

Marine Pollution Bulletin, Год журнала: 2023, Номер 199, С. 115466 - 115466

Understanding microplastic (MP) behavior in oceans is crucial for reducing marine plastic pollution. However, the complex process underlying MP transportation to deep seafloor remains unknown despite sea being considered its major sink. We focused on distribution Sagami Bay (adjacent highly populated areas of Japan), plate triple junction connected through Trough, and abyssal plain immediately below Kuroshio Extension. observed highest number MPs stations, more than previously reported. The polymer types aspect ratio stations significantly differed from those bathyal/hadal stations. study suggests that accumulated open ocean surface layer sink plains it, while land sources accumulate bathyal depth are transported hadal near coast turbidity currents along submarine canyon.

Are you drowned in microplastic pollution? A brief insight on the current knowledge for early career researchers developing novel remediation strategies

Microplastics (MPs) composed of different polymers with various shapes, within a vast granulometric distribution (1 μm - 5 mm) and wide variety physicochemical surface bulk characteristics spiral around the globe, atmospheric, oceanic, cryospheric, terrestrial residence times, while interacting other pollutants biota. The challenges microplastic pollution are related to complex relationships between generation mechanisms (physical, chemical, biological), their properties, interactions microorganisms, changes in properties aging, small sizes that facilitate diffusion transportation air, water, land, biota, thereby promoting ubiquity. Early career researchers (ERCs) constitute an essential part scientific community committed overcoming new ideas innovative perspectives for development remediation technologies. However, because enormous amount information available, it may be difficult ERCs determine complexity this environmental issue. This mini-review aims provide quick updated overview insights help them acquire background needed develop highly physical, biological technologies, as well valorization proposals education awareness campaigns. Moreover, recommendations holistic strategies presented here can propose technologies considering environmental, social, practical dimensions fulfilling current government policies manage plastic waste.
