Finding F-1028

“The mean indoor CO, CO2, and TVOCs concentrations in the preservation environment were 0.75 ± 0.21 ppm, 368.91 ± 32.23 ppm, and 320.03 ± 44.20 μg/m3, respectively, satisfying the standards set by the MOE, as was the case for SO2 and NOX.”

Structure

Factor: Carbon dioxide (CO₂)
Setting: archive repository, KR
Study design: technical note on the indoor air of an archive repository: carbon monoxide, carbon dioxide, total volatile organic compounds, sulphur dioxide, nitrogen oxides, individual volatile compounds and aldehydes measured indoors and outdoors on two floors (class 4)
Effect: mean 368.91
Caveat: an archive kept for preservation, so the levels say what a controlled store looks like rather than a dwelling
