Scenario.


Every time we exhale, we make the air around us a little less hospitable. Every place we go, we raise CO2 levels. We do not normally convert PPM concentrations of a gas by volume into weight for CO2 or other gases; the gas detection tube or gas monitoring device is giving us a direct reading of PPM in the air being tested.

However, concentrations may also be expressed as 2016-12-04 However, on an average, a normal human being exhales about 35 to 50K ppm per day; and if there is inadequate ventilation then the exhaled CO2 accumulates. Let's take an example, in an enclosed space of 3.5m X 4m, with single occupancy, without any ventilation, CO2 will increase from 500ppm to … Carbon Dioxide (CO2) in air is normally measured in Parts Per Million (ppm). At 1,000 ppm CO2, a volume or air containing one million air molecules would contain a mixture of 999,000 air molecules and 1,000 CO2 molecules. The volume of air necessary to contain one million air molecules is affected by air temperature and … Stabilize CO2.

The SI unit for CO2 concentration is µmol per   Indoor air quality also appears to influence rates of absence, work performance, and 350 ppm and indoor CO2 generation rate is 0.31 Lmin-1 per person.

This is more than what had happened naturally over a 20,000 year period (from the Last Glacial Maximum to 1850, from 185 ppm to 280 ppm).
