Finding F-1231

“As shown in Figure 2, the ratios (CS/CE) of concentrations of the confirmed compounds and TVOC measured in Brand A in sunshine condition (CS) to that in the environment test chamber (CE) were greater than 1, indicating that the VOCs and TVOC pollution concentrations in the three model vehicles increased sharply when the temperature rose from 28.7 °C to 61.5 °C.”

Structure

Factor: Total volatile organic compounds (TVOC)
Method: Emission test chamber method
Setting: car cabin, CN
Study design: measurement study of vehicle interior air quality in new vehicles of three brands in China, sampled under the Chinese method standard HJ/T 400-2007: each vehicle tested statically in an environment test chamber at 25 degrees Celsius and again in sunshine on a windless summer day, and then under driving conditions, with total volatile organic compounds and eight confirmed compounds measured by gas chromatography with mass spectrometry and by high performance liquid chromatography (class 4)
Caveat: the sentence states only that every ratio is greater than 1; the individual ratios are in the study's Figure 2 and are not taken
