CO-koncentration mäts i enheten ppm (parts per million). Som komplement till den aktuella koncentrationsnivån kan man även mäta medelvärdet över en given tidsperiod. Tabellen nedan summerar några hälsoeffekter som orsakas av förlängd exponering av kolmonoxid. The peak CO level for employees engaged in roll-on roll-off operations during cargo loading and unloading is 200 ppm. ASHRAE Carbon Monoxide Exposure Limits The American Society of Heating, Refrigerating and Air-Conditioning Engineers ASHRAE is a voluntary world-wide organization that sets standards for members focused on building systems, energy efficiency, indoor air quality, refrigeration Koldioxid (CO 2) är en färglös och luktfri gas med en svagt sur smak.CO 2 är molekylformeln för den kemiska föreningen mellan grundämnena kol (C) och syre (O). Gasen förekommer i vår atmosfär med en halt på ca 400 ppm, dock kan halten uppgå till 800 ppm i miljöer med höga utsläpp, t.ex. i storstäder, industriområden, trafikleder etc.

Ceiling - An upper limit on the concentration of CO at any moment Expressway CO levels approached 25-100 ppm. The EPA emission standards have reduced the amount of carbon monoxide produced by over 95%. Still, a single vehicle emitting high concentrations of CO can leave a plume (cloud) of carbon monoxide. Following the dirty vehicle and driving in the plume can cause health problems for some people.
