One model of mask distributed to Quebec schools and daycares may be dangerous for the lungs as they could contain a potentially toxic material, according to a directive sent out by the provincial government on Friday.
Radio-Canada has obtained documents showing Health Canada warned of the potential for “early pulmonary toxicity” from the SNN200642 masks which are made in China and sold and distributed by Métallifer, a Quebec-based manufacturer.
“If you have this type of mask in stock, we ask that you stop distributing them and keep them in a safe place now,” the provincial government says in the directive that was sent by three ministries: education, families and higher education.
Some daycare educators had been suspicious of these grey and blue masks for a while because they felt like they were swallowing cat hair while wearing them, Radio-Canada has learned.
Health Canada conducted a preliminary risk assessment which revealed a potential for early lung damage associated with inhalation of microscopic graphene particles. Graphene is a strong, very thin material that is used in fabrication, but it can be harmful to lungs when inhaled and can cause long-term health problems.
As a former commissioner on the congressionally chartered U.S.–China Economic and Security Review Commission, identifying toxic ingredients from China in American products has always been a grave concern for me. In its 2019 report to Congress, the commission noted China was the No. 1 global source of pharmaceutical ingredients, which includes dietary supplements for pet consumption.
As far back as 2007, we found rampant agricultural contamination by airborne pollutants as a result of China’s rapid growth, conflicting layers of oversight, oppressive control of state media, and China’s tacit refusal to enforce its own product safety laws.

A town in Florida has been target of a hack which briefly altered chemicals in its water supply to “potentially damaging levels” according to local media reports. Federal and local authorities are currently investigating the computer network intrusion which happened last Friday morning, the alarming details of which are emerging Monday.
Plant operators overseeing the small city of Oldsmar’s water supply began observing strange activity on their monitors. That’s when technicians noticed that sodium hydroxide levels (or lye), which is used to treat the city’s water in small amounts in order to control acidity while removing heavy metals, was being remotely pushed higher.
Technicians noticed the chemical levels being subject of unauthorized external manipulation in real-time and immediately moved to restore the sodium hydroxide input to its safe, correct levels. The AP detailed based on local reporting: “A plant worker first noticed the unusual activity at around 8 a.m. Friday when someone briefly accessed the system.”
“At about 1:30 p.m., someone accessed it again, took control of the mouse, directed it to the software that controls water treatment and increased the amount of sodium hydroxide,“ the report continued.
The hacker or hackers have yet to be uncovered and apprehended.
