Values are expressed relative to pre-industrial conditions (CO2 = 280 ppm; in atmospheric pCO2 and orbital forcing at the obliquity time scale (30–40 k.y.)"
Det betyder at evnen til at koncentrere sig nedsættes markant, desuden giver det fysisk ubehag som hovedpine og træthed. Mid-ocean ridge volcanism is the “key contributor” to the CO2 flux from the Earth’s mantle to the sea surface. It has previously been observed that the acid pouring into the abyssal ocean from seafloor volcanism may contain about 9,000 to 57,000 ppm CO2 concentrations (Helo et al., 2011).

by removing carbon dioxide from compressed air down to 10 ppm or 1 ppm; by removing moisture from compressed air below 0.5 ppm (-70°C/-70°F)
2021-04-10 If you just want the total CO2 that is in the empty 200 liters. Convert from ppm to g/m^3 as explained above, then realize that 1 m^3 = 1000 liters, so the gas phase part of your tank is 1/5 of a cubic meter. If you are interested in total CO2, however, you need to worry about what's dissolved in your liquid.
