Scientists Uncover Nanoplastics and Other Pollutants Released from Disposable Face Masks Written by AZoNanoMay 5 2021 Swansea University scientists have uncovered potentially dangerous chemical pollutants that are released from disposable face masks when submerged in water. The research reveals high levels of pollutants, including lead, antimony, and copper, within the silicon-based and plastic fibres of common disposable face masks. The work is supported by the Institute for Innovative Materials, Processing and Numerical Technologies (IMPACT) and the SPECIFIC Innovation & Knowledge Centre Project lead Dr Sarper Sarp of Swansea University College of Engineering said: "All of us need to keep wearing masks as they are essential in ending the pandemic. But we also urgently need more research and regulation on mask production, so we can reduce any risks to the environment and human health".
