Antarctic wastewater: A local source of microplastic pollution
AI summary Read the abstract
Researchers identified for the first time that a wastewater treatment plant in Antarctica is a local source of microplastic pollution, detecting 64 to 159 particles per liter of wastewater. Over 90% of the identified particles were smaller than 50 micrometers, comprising common polymer types including polyethylene, polypropylene, and PET, demonstrating the need for improved treatment technologies even in remote polar regions.
Microplastic (MP) particles can be found all around the planet, even in Antarctica where they can be locally originated or transported by marine currents and winds. In this communication, we identify and report for the first time the contribution of a wastewater treatment plant (WWTP) as a local source of MP particles in the region. The analysis of the entire sample using micro-Raman spectroscopy revealed an MP concentration that ranged from 64 to 159 particles per liter of wastewater. >90 % of the identified particles were smaller than 50 μm. Among those analyzed, microplastics were identified as polyethylene, polypropylene, polyvinyl chloride, polytetrafluoroethylene, polyethylene terephthalate, and polystyrene. These findings demonstrate the need for urgent policies and technologies to mitigate this MP contamination source.
