Observation, prediction, and risk assessment of volatile organic compounds in a vehicle cabin environment
Open accessAbstract
While vehicle cabin environment significantly impacts human health, systematic studies on this important microenvironment are lacking. Here, we conduct a 12-day field observation of a new car under varying environmental conditions. Concentrations of 20 common volatile organic compounds are determined. Levels of formaldehyde and acetaldehyde exceed the suggested limit, with 34.9% and 60.5% over the standard rate, respectively. By combining an improved multi-source model with quantitative correlations between three key parameters of volatile compound emissions from various in-cabin materials and temperatures, we predict formaldehyde concentrations at different temperatures, which are consistent with measurements. We find that volatile compound emission characteristics are dependent on material surface temperature rather than the widely used metric of air temperature. This study probes volatile compound variability in a realistic vehicle cabin via observation and modeling and estimates in-cabin incremental lifetime cancer risk via three exposure routes, indicating a high health risk for drivers.

In a space cabin, the existence of hardware, thermal degradation of polymeric materials, and even the human themselves (metabolism) contribute to the emissions of many kinds of toxic pollutants, e.g., formaldehyde, ammonia, benzene, which may pose adverse health effects on the crew.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
