Canada issues graphene mask recall in health concerns


Canadian health officials have announced a prophylactic recall of masks containing graphene, a nanomaterial composed of a single layer of carbon atoms. He states that health risks need to be studied after studies in animals have revealed that the substance has “some potential” to cause lung toxicity.

recall, Issued on friday Health Canada is urging Canadians not to use masks containing graphene or biomass graphene as small particles can be inhaled. This can pose a health risk.

The advisory cites studies showing that inhaled graphene particles “may cause premature lung toxicity in animals,” but the health risks to humans are still unknown and require further research. It states that there is.

Health Canada said it is working with mask manufacturers to assess potential impacts on people’s health.

“We are taking a proactive approach to removing them from the market while continuing to collect and evaluate information until the department has completed a thorough scientific evaluation and established the safety and effectiveness of graphene-containing face masks. “The agency said.

Mask design can affect the likelihood of inhaling graphene particles, but all other variables such as the type of graphene used and the amount and duration of exposure to the substance all affect health risk. It’s likely, says Health Canada.

Authorities are currently not using masks and are calling on people to report adverse events at Health Canada. Reporting platform..

Masks containing graphene have been sold and used by adults and children in Canadian schools and day care, and may have been distributed for use in the medical setting, officials said.Canadian Media reported Approximately 4.6 million graphene-coated masks have been distributed to schools by the Government of Quebec, a Canadian province, but it is unknown how widely used masks are.

Graphene was discovered by Andre Geim and Konstantin Novoselov of the University of Manchester in 2004 and was awarded the 2010 Nobel Prize in Physics for its discovery. It is a new one-atom-thick nanomaterial that can be used in a variety of applications, including small antennas, computer chips, and coatings that absorb potentially harmful waves.

Health Canada noted that the substance has been reported to have antiviral and antibacterial properties, adding that some of the “COVID-19 claimed” graphene-containing masks are sold in the Canadian market. I did.

Researchers at the University of Hong Kong have produced a graphene mask with “80% antibacterial efficiency.” Recent press release The team has not yet tested with the CCP (Chinese Communist Party) virus, a new coronavirus that causes COVID-19, but was published in ScienceDaily and has “very promising results inactive” for the two coronaviruses. It will be transformed. “

According to the release, a research team at City University of Hong Kong is working with a research institute in mainland China to test graphene materials with two types of human coronavirus.

“Initial tests showed over 90 inactivated [percent] Almost 100 viruses in 5 minutes [percent] In 10 minutes in the sunlight. The team will later test with the COVID-19 virus, “said the release.
