Plastic occurrence, sources, and impacts in Antarctic environment and biota

Water Biology and Security, Год журнала: 2022, Номер 1(2), С. 100034 - 100034

Several studies have documented that plastic pollution is affecting one of the most remote and pristine regions our planet, Antarctica. Plastics different size polymeric composition been retrieved in Antarctic sea ice, surface waters sediments, with microplastics (mostly fibers) found both terrestrial marine organisms. Such evidence raises concerns about potential detrimental effects on biodiversity ecosystem functions. The present review aims to report up-to-date knowledge occurrence distribution environment biota including interaction microorganisms, sources, its impact biota. Our understanding this polar region will help us define human footprint Antarctica predict future ecological risks.

The number of scientists and tourists visiting Antarctica is on the rise and, despite management framework for environmental protection, some coastal areas, particularly in Antarctic Peninsula region, are affected by plastic contamination. few data available occurrence microplastics (<5 mm) difficult to compare, due different methodologies used monitoring studies. However, indications emerging guide future research implement protocols. In surface subsurface waters Southern Ocean, debris >300 µm appears be scarce far less abundant than paint chips released from vessels. Yet, near scientific stations, fragmentation degradation larger items, as well microbeads microfibers into wastewater personal care products laundry, could potentially affect marine organisms. Some studies indicate that, through long-range atmospheric transport, fibers produced other continents can deposited Antarctica.

Microplastic Interactions and Possible Combined Biological Effects in Antarctic Marine Ecosystems

Antarctica and the Southern Ocean are most remote regions on Earth, their quite pristine environmental conditions increasingly threatened by local scientific, tourism fishing activities long-range transport of persistent anthropogenic contaminants from lower latitudes. Plastic debris has become one pervasive ubiquitous synthetic wastes in global environment, even at some coastal Antarctic sites it is common enduring evidence past recent human activities. Despite growing scientific interest occurrence microplastics (MPs) lack standardized methodologies for collection, analysis assessment sample contamination field lab does not allow us to establish bioavailability potential impact. Overall, appears be little-affected plastic contamination, with exception marine ecosystems impacted wastewater stations tourist vessels or Microplastics have been detected sediments, benthic organisms, krill fish, but there no clear transfer seabirds mammals. Therefore, we suggest directing future research towards standardization methodologies, focusing attention nanoplastics (which probably represent greatest biological risks) considering interactions MPs macro- microalgae (especially sea-ice algae) formation epiplastic communities. In directly activities, combined exposure paint chips, metals, organic pollutants (POPs), emerging (CEI) pathogenic microorganisms represents a danger organisms. Moreover, very sensitive water acidification shown remarkable decrease years. These climate-related stresses could reduce resilience increasing impact microorganisms.

Progress in selecting marine bioindicators for nanoplastics ecological risk assessment

Ecological Indicators, Год журнала: 2023, Номер 154, С. 110836 - 110836

Nanoplastic (<1 µm) pollution in the marine environment is a cause of growing concern due to current difficulties measuring their occurrence abiotic and biotic matrices, with consequent uncertainties on ecological risk for natural communities associated ecosystem services. Most investigations dealing nano-ecotoxicity have been conducted bench-scale by examining effects single model species under short-term exposure conditions at high concentrations (>50 mgL−1). Both negligible impacts detrimental effects, although poorly descriptive real environmental scenarios, documented different trophic levels functionalities. Polystyrene nanospheres (<100 nm) are far most tested as proxy nanoplastics, even though nanoplastics composed other polymers shapes (i.e., irregular fibers) has reported seawater column sediments. Limited information bioaccumulation hamper selection key bioindicator following various criteria target, highly sensitive, endangered, etc) monitoring assessment (ERA) purposes. A holistic approach thus required starting from setting environmentally relevant coupled chronic exposure, selecting bioindicators including those having role processes, functions services, also human consumption (shellfish seafood). The present mini-review aims provide framework best nanoplastic along knowledge sources, circulation behavior temperate polar environments potential compartments/species more support ERA. Less investigated niches habitats, which should deserve attention future studies, identified.
