Finding F-1121

“Acetaldehyde (3.81–36.0 μg/m3), formaldehyde (3.26–26.7 μg/m3), n-tetradecane (below the method quantification limit (<MQL) to 47.7 μg/m3), toluene (4.23–78.3 μg/m3), and n-undecane (<MQL to 6.24 μg/m3) concentrations exceeded method detection limits in all the investigated car cabins.”

Car indoor air pollution by volatile organic compounds and aldehydes in Japan… (2016). AIMS Environmental Science. Page 9. CKB 0139

Structure

Factor: Formaldehyde (CH₂O)
Setting: car cabin, JP
Study design: measurement study of 24 car cabins in Japan: volatile organic compounds and aldehydes sampled inside the cabins with outdoor air for comparison, against the advisable values of the Japanese Ministry of Health, Labour and Welfare, with a screening-level risk assessment (class 4)
Effect: other 26.7
Sample: 24 measurements
Caveat: the sentence gives a range for each compound; the upper end is the estimate and the whole range sits in dispersion
