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.
In recent years, microplastic pollution has become one of the major global concerns and represents a complex, multidimensional, and multisectoral reality. The considerable existing data relating to microplastic pollution in matrices such as water and soil suggests that microplastics are widespread globally, but there are several knowledge gaps regarding their actual distribution mostly in remote locations far from sources. In this review we examine current knowledge on microplastic pollution in the Antarctic continent. Antarctica, the unique continent not permanently anthropized, is the southernmost part of the planet but its geographic isolation does not protect against the harmful impact of human activities. This continent is characterized by limited internal pollution sources but high-burden external routes of contaminants and represents a unique natural laboratory to analyze how pollution can reach every part of the biosphere. This review reports the presence of microplastics in organic and inorganic matrices not only at marine level (water, sediments, benthic organisms, krill, and fish) but also in freshwater (lakes, rivers, snow, and glaciers) highlighting that microplastic contamination is endemic in the Antarctic environment. Microplastic pollution is of great environmental concern everywhere, but the characteristics of remote ecosystems suggest that they could be more sensitive to harm from this pollution.

This review summarizes existing research on microplastic pollution in Antarctica, covering how these tiny plastic particles reach even the most remote environments through fishing, tourism, and ocean currents. Despite Antarctica being considered pristine, microplastics have been found in both water and sediment across the region. The findings highlight that no place on Earth is free from microplastic contamination, raising concerns about effects on wildlife and ecosystems that are connected to global food chains.
The transport and fate of microplastic fibres in the Antarctic: The role of multiple global processes
AI summary Read the abstract
Researchers investigated microplastic contamination across air, seawater, and sediment samples in the Antarctic Weddell Sea and identified 47 distinct microplastic categories, predominantly fibers. The overlap of fiber types across different sample media suggests that microplastics reach Antarctica through multiple transportation pathways, including atmospheric and oceanic currents. The study demonstrates that even one of the most remote regions on Earth is affected by diffuse microplastic pollution from global sources.
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.
