Scientists have discovered microplastic in the snow of remote areas in Antarctica for the first time, according to a study by the British Antarctic Survey, reported by the Daily Mail.
The samples were taken from research stations near the Union and Schanz glaciers. Analysis revealed microplastic particles in concentrations ranging from 73 to 3,099 particles per liter of snow. About 95 percent of the particles were less than 50 micrometers in size. Dr. Clara Manno, an oceanographer with the British Antarctic Survey, pointed to possible sources of the microplastic, including outdoor clothing and ropes and flags used to mark safe paths in and around the camp.
The article also highlights the potential negative impacts of the discovered particles on the environment, where the strict regulations for brought items have previously ensured the absence of similar findings. Kirstie Jones-Williams, a co-author of the study, lamented that “there is no truly untouched place on Earth.”
Additionally, the report references earlier studies, mentioning that microplastic can accelerate snow melting. Antarctica is also home to a variety of species, including penguins, seals and fish, in which microplastic has been found in their bodies.
Researchers expressed hope that the findings would contribute to emphasizing the urgent need to curb the global spread of plastic pollution. In February, scientists announced that the number of microplastic particles in the human brain had increased by 50 percent over the past eight years, with the current concentration reaching around 4,800 micrograms on average, enough for a small plastic spoon.
Microplastic is defined as any plastic particle smaller than five millimeters in size. There are primary and secondary forms of microplastic. Primary microplastic is used in cosmetics, toothpaste and household chemicals, while secondary microplastic is formed when plastic objects, such as bags, cups, disposable cutlery, fishing nets and more, break down into smaller pieces after exposure to heat, air, water and salt.
