av LE Øi · 2014 · Citerat av 7 — The level of accepted water content after dehydration depends on the next step for the captured CO2, and can be in the range between 5 and 500 parts per million From the current level of about 380 parts per million in the atmosphere, further CO2 increases will have a trivial effect. Med tanke på de nuvarande nivåerna på Carbon dioxide (CO2) levels are a key indicator of indoor air quality in schools, colleges, offices, cinemas, 2.5 %rh, 0.3 C, 30 ppm CO2 +5 % measured value. carbon dioxide concentration levels, air temperature, and relative humidity.

David R. writes, “Our studies found carbon dioxide levels rise to over 3,000ppm from 400ppm (outdoor air) in 30 minutes in an enclosed automobile with a single passenger.” In fact, studies show that drowsiness accounts for between 10 and 30% of all automobile accidents and high CO2 levels are known to cause drowsiness. 2020-06-10 · May 2020 hit a record high, 417 parts per million (ppm) carbon dioxide as measured at the Mauna Loa Observatory, which has continually measured CO2 in the atmosphere since 1958. Even low carbon monoxide levels over long periods can have an impact on brain chemistry. While exact short term and long term CO levels recommended by ASHRAE, OSHA, NIOSH and other organizations differ, the consensus is that 9 ppm (parts-per-million) is the maximum indoor safe carbon monoxide level over 8 hours.
