The article confuses Nitrogen Monoxide (NO), Nitrogen Dioxide (NO2) and Nitrous Oxide (N2O). I know this as a few kids in chemistry class a few decades ago thought they'd sneak into the the lab and make laughing gas (N2O). The made Nitrogen Dioxide (NO2), inhaled it and hospitalised themselves! Not a laughing matter (at least not for them). Anyway, I digress, but if you're going to write an article about gases, at least get the names and formulae right...
