ppm - parts per million; Normal CO 2 Levels. The effects of CO 2 on adults at good health can be summarized to: normal outdoor level: 350 - 450 ppm; acceptable levels: < 600 ppm; complaints of stuffiness and odors: 600 - 1000 ppm; ASHRAE and OSHA standards: 1000 ppm; general drowsiness: 1000 - 2500 ppm; adverse health effects may be expected: 2500 - 5000 ppm

At lower concentrations, e.g. 100 parts per million (PPM), the detector does not sound an alarm for many tens of minutes. At 400 PPM, the alarm sounds within a few minutes. This concentration-time function is intended to mimic the uptake of carbon monoxide in the body while also preventing false alarms due to brief bursts of carbon monoxide

CO2 PPM - Trends in Atmospheric Carbon Dioxide. Data are sourced from the US Government's Earth System Research Laboratory, Global Monitoring Division. Two main series are provided: the Mauna Loa series (which has the longest continuous series since 1958) and a Global Average series (a global average over marine surface sites).

As of 2001, measured atmospheric concentrations of carbon dioxide were 100 ppm higher than pre-industrial levels. Natural sources of carbon dioxide are more than 20 times greater than sources due to human activity, [9] but over periods longer than a few years natural sources are closely balanced by natural sinks, mainly photosynthesis of carbon Some express the concentrations as ppmv (parts per million by volume) and some express the concentrations as mg/m 3 (milligrams per cubic meter), while others require adjusting or correcting the concentrations to reference conditions of moisture content, oxygen content or carbon dioxide content.
