“The devices do not improve air quality but can be used to gauge whether a room is well or poorly ventilated. Since COVID-19 can spread through the air, they’ve also been used as COVID risk assessment tools.”
“ “If CO2 is increasing in a room, it means you’re not evacuating one of the contaminants accumulating, so that’s probably the case with the others,” explained Stéphane Bilodeau, an indoor ventilation expert and lecturer in the bioengineering department at McGill University.”
“How much of the air you're breathing is air someone else exhaled? And in the midst of a pandemic caused by an airborne virus, where are the riskiest places to be? In the first in a series of five stories Farah Hancock reports on hot spots of hazardous air.”
“Shuffling my way onto the bus I had no idea it might be the most dangerous thing I would do all day…
From a level of 516 parts per million at the bus stop, it took only 20 minutes for CO2 inside the bus to peak at a whopping 5737ppm.”
“Although many public health officials still dismiss COVID infections as inevitable and even beneficial, a growing body of science shows this fashionable dogma is dangerously wrongheaded, if not an outright form of malpractice.”
“Reinfections, and 2022 is surely the year of reinfections, just increase the damage from COVID, which can be profound: immune dysregulation, blood clots, nerve cell death, inflammation, lung damage, kidney failure and brain damage.”
