Microplastics and Nanoplastics in Antarctica. Considerations on Their Impact on Ecosystems and Human and Fauna Health
AI summary Read the abstract
This review examines the current state of knowledge about microplastic and nanoplastic contamination in Antarctica, assessing concentrations detected in air, water, sediment, and biota across the continent. The authors discuss the vulnerability of polar ecosystems to plastic pollution and the challenges of attribution given long-range atmospheric and oceanic transport pathways.
In recent years, microplastics and nanoplastics have been identified in a range of remote environments, including Antarctica.However, data throughout the Southern Hemisphere, particularly Antarctica, are largely absent.Microplastics and nanoplastics have negative effects on marine organisms and act as vectors for persistent organic pollutants and other toxic substances, which are harmful to aquatic environments and organisms.Microplastics and nanoplastics also pose serious problems for human health, especially due to its nanotoxic capacity, of which the mechanisms are not yet fully established.Microplastics and nanoplastics have been recognized as widespread pollutants in the marine environment and are known to be damaging to terrestrial and aquatic ecosystems, while their small size and relatively low density also allow them to become airborne and transported over large distances.This work summarizes the results of different research carried out by the various Antarctic programs in marine and terrestrial ecosystems of Antarctica.In addition, we analyze the knowlege about potencial nanotoxicity of nanoplastics and underscore the need for further research and development in this field.

Pollution Has No Borders: Microplastics in Antarctica
AI summary Read the abstract
This review documents the spread of microplastics throughout Antarctica -- in seawater, sediments, freshwater lakes, snow, glaciers, and marine organisms -- despite the continent having minimal local pollution sources. The findings demonstrate that microplastic contamination is truly global, reaching even the most isolated ecosystems on Earth through atmospheric and ocean currents.
Plastic occurrence, sources, and impacts in Antarctic environment and biota

This review summarized evidence for microplastic contamination in Arctic and Antarctic environments — including water, sea ice, sediment, and biota — characterizing polar regions as sinks for globally transported plastic particles and calling for improved monitoring to track long-term trends.
Microplastic Pollution in Antarctic Environments
AI summary Read the abstract
This review examines microplastic pollution in Antarctic environments, summarizing evidence that even this remote continent has been contaminated by plastic particles, with implications for its unique fauna, influence on global climate systems, and value as a pristine scientific reference site.
Microplastics in Antarctic air: revealing current findings
AI summary Read the abstract
This review examines the growing body of evidence on microplastic air pollution in Antarctica, one of the most remote places on Earth. Researchers found that both micro- and nanoplastics have been detected in Antarctic air, posing potential threats to this fragile ecosystem and its freshwater reserves. The study emphasizes that global action to reduce microplastic emissions is essential, since these particles can travel vast distances through the atmosphere.
