Scientists of Swansea University have released potentially dangerous chemical pollutants released from the disposable facial masks when immersed in water.
Research shows high pollutant levels, including lead, antimony and copper, within the silicon base and plastic fibers of the usual disposable facial masks.
The work is supported by the Institute for Innovative Materials, Processing and Numerical Technologies (Impact) and the Specific Innovation and Knowledge Center.
Project management Dr. Sarper Sarp The Swansea University College of Engineering said: "We all have to wear masks, as they are essential at the termination of the pandemic. But we also urgently need more research and regulation for mask production, so we can urgently research and regulation for mask production Reduce all the risks to the environment and human health. "
In a recent paper sketched tests used by the research team used a variety of masks - from standard normal facial masks to novelty and festive masks for children with many currently in British retail stores.
The increase in import masks, and the associated waste, due to the COVID 19 pandemic was documented as a new cause of pollution. The study aimed to explore this direct link - with investigations to determine the level of existing toxic substances.
The results show significant pollutant levels in all tested masks - with micro / nanoparticles and heavy metals that are dissolved in the water during all tests. The researchers concludes that this will have a significant environmental impact and additionally the issue of potential damage to public health - warning that a repeated exposure could be dangerous because the found substances found are known to cell death, genotoxicity and cancer formation.
To combat this, the team recommends further research and subsequent rules in the manufacturing and examination processes.
Dr Sarper Sarp continued: "The production of disposable plastic facial masks (DPFS) in China alone is achieved alone in a global effort to address the spread of the new SARS COV-2 virus. However, improper and Unregulated disposal of these DPFS is a problem with plastic pollution that we already face, and will only intensify.
"With regard to the amount of evidence suggests that DPFS waste may possibly have a significant environmental impact by releasing pollutants by simply exposing them to water. Many of the toxic pollutants found in our research became bioaccumulative properties, if in the environment and our findings show that DPFS could be one of the main sources of these environmental impurities during and after the Covid-19 pandemic.
"It is therefore absolutely necessary for stricter rules to be enforced during manufacture and disposal / recycling of DPFS to minimize the environmental impact.
"There is also a need to understand the effects of such particles leaching on public health. One of the main concerns with these particles is that they were easily separated from face masks and without stirring into the water, which indicates it To these particles are mechanically unstable and easily available to be dissolved.
"Therefore, a complete investigation is required to determine the amounts and potential effects of these particles into the environment, and the levels that are inhaled by the users during normal breath. This is a significant concern, especially for health professionals, Key workers and children who need to wear masks for large proportions of work or school days. "
