Breath CO monitor displaying carbon monoxide concentration of an exhaled breath sample (in ppm) with its corresponding percent concentration of carboxyhemoglobin. As many symptoms of carbon monoxide poisoning also occur with many other types of poisonings and infections (such as the flu), the diagnosis is often difficult.

WMO:s rapport Greenhouse Gas Bulletin 2016 säger att den snabba ökningen av koldioxid och andra växthusgaser i atmosfären kan starta förändringar i klimatsystemet som aldrig tidigare förekommit. No standards for CO have been agreed upon for indoor air. The U.S. National Ambient Air Quality Standards for outdoor air are 9 ppm (40,000 micrograms per meter cubed) for 8 hours, and 35 ppm for 1 hour.

In the home a concentration of no more than 9 PPM is recommended. Parts per million (z angličtiny, česky „dílů či částic na jeden milion“), zkráceně též ppm, je výraz pro jednu miliontinu (celku); někdy je tento výraz odvozován i z latinského pars per milion.
