Car cabin atmosphere quatilty: vehicle interior toxicity assesment based on In vitro tests

Abstract

In the article the problem of vehicle interior as an important environment of human life hase been discussed. The problem is very important in aspect of indoor air quality. A vehicle interior is a specific environment where levels of volatile toxic organic compounds concentrations are particularly high. In the article the results of statistical analysis of human resistance time in vehicle interior are presented. A method of gaseous mixtures toxicity estimation based on in vitro tests has been proposed in application for vehicle cabin interior and compared to the popular toxicity indicators (relative toxicity coefficients). The results of the method application in brand new passenger vehicles (in parking conditions) are presented. The results was correlated with volatile organic compounds concentration in vehicles interior (method: gas chromatography).
