Environments, Год журнала: 2023, Номер 10(9), С. 161 - 161

In recent years, interest in the impact of environmental pollutants on ecosystem has increased significantly, with particular attention being paid to relationship between climate change and aquatic world. This is because increasing pollution causing fundamental changes welfare animals marine ecosystem. A primary focus microplastics (MPs) nanoplastics (NPs), as evidenced by our bibliometric network analysis (BNA). However, while research focused accumulation these organisms, their effects redox homeostasis are still seldom discussed despite role played reactive oxygen species mitochondrial well-being maintaining an optimal state health. some scientific evidence suggests that MPs NPs organisms at base trophic chain can cause a transfer substances towards more complex reaching humans through consumption fauna food. Therefore, this review, we have tried discuss oxidative stress even if studies regard scarce.

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.

The Abundance of Microplastics in the World’s Oceans: A Systematic Review

Oceans, Год журнала: 2024, Номер 5(3), С. 398 - 428

Опубликована: Июнь 21, 2024

Microplastics are ubiquitous in marine environments and have been documented across all ocean compartments, especially surface waters, the world. Even though several studies identify presence of microplastics world’s five oceans, there remains an overt problem large inconsistencies their sampling, extraction, consequent quantification. Despite complexity these methodologies, researchers tried to explore microplastic abundance waters. Using a systematic review approach, dataset was derived from 73 primary undertaken since year 2010 following Oslo Paris Conventions (OSPAR) guidelines monitor harmonise debris. The results showed differences distribution waters oceans. overall concentration oceans ranged between 0.002 62.50 items/m3, with mean 2.76 items/m3. highest found Atlantic (4.98 items/m3), while least observed Southern Ocean (0.04 items/m3). While challenging, this paper recommends harmonisation separation, identification methods globe aid design appropriate mitigation strategies for reducing plastic pollution.

Life in the Midwater: The Ecology of Deep Pelagic Animals

Annual Review of Marine Science, Год журнала: 2024, Номер 16(1), С. 383 - 416

Опубликована: Янв. 17, 2024

The water column of the deep ocean is dark, cold, low in food, and under crushing pressures, yet it full diverse life. Due to its enormous volume, this mesopelagic zone home some most abundant animals on planet. Rather than struggling survive, they thrive—owing a broad set adaptations for feeding, behavior, physiology. Our understanding these constrained by tools available exploring sea, but tool kit expanding along with technological advances. Each time we apply new method depths, gain surprising insights about genetics, ecology, physiology, diversity, dynamics change. These discoveries show structure within seemingly uniform habitat, limits inexhaustible resources, vulnerability impervious environment. To understand midwater need reimagine rules that govern terrestrial ecosystems. By spending more at depth—with whatever are available—we can fill knowledge gaps better link ecology environment throughout column.

High concentrations of microplastic (MP) particles have been reported in the Arctic Ocean. However, studies on high-resolution lateral and vertical transport MPs from European waters to are still scarce. Here, we provide information about compositions surface, subsurface, deeper (< 1 m, ~ 4 17–1679 m) collected at 18 stations six transects along Norwegian Coastal Current (NCC) using an improved Neuston Catamaran, COntinuos MicroPlastic Automatic Sampling System (COMPASS), situ pumps, respectively. FTIR microscopy spectroscopy were applied measure MP concentration, polymer composition, size distribution. Results indicate that small microplastics (SMPs, <300 μm) varied considerably (0–1240 m−3) within water column, with significantly higher surface (189 subsurface (38 compared (16 m−3). Furthermore, average concentration SMPs samples was four orders magnitude than abundance large (LMPs, >300 μm), overall, <50 μm account for >80 % all detected MPs. no statistically significant geographical patterns observed SMP surface/subsurface seawaters between sampling transects, suggesting a relatively homogeneous horizontal distribution upper ocean NCC/Norwegian Atlantic (NwAC) interface. The Lagrangian particle dispersal simulation model further enabled us assess large-scale Northern Arctic.
