Air composition inside the cabins of nine new vehicles of the same model, but with different interior equipments and materials used, was examined. Air samples were collected short after vehicles' production date. None of the vehicle was driven before sampling. Air pollution was assessed on the basis of the concentration of different volatile organic compounds (VOCs) and total VOC. Since only new vehicles were under study, it can be stated that different VOCs, present in vehicle cabin, were emitted from interior materials. The main aim of the present work was to answer the question about the representativeness of collected air samples and intra-model variability of VOCs concentrations. Air samples were collected by an active method onto duplicate Carbograph 1TD and Tenax TA sorbents. VOCs were thermally desorbed and analyzed with the use of the TD-GC-FID/MS method. Quantitative and qualitative analyses as well as statistical calculations were performed. Total VOCs concentration ranged from 1.5 to 2.1 mg/m 3 in vehicles tested. About 200 different organic compounds were detected in each vehicle interior. Strong linear correlation was observed for concentrations of some kind of compounds.

The investigation of air pollution is a highly important field of research. Air quality in a vehicle's interior has attracted growing attention since people spend much of their time in vehicles and those frequently travelling in new cars are exposed to harmful compounds. The main air pollutants inside new vehicles are volatile organic compounds (VOCs), present as a result of interior materials' de-gassing. Among the sampling methods used in indoor air quality research, active sampling for VOCs collection is one method that has been extensively described and applied. The present study sought to implement passive sampling with Radiello samplers to collect air samples directly in the car factory. The results from passive sampling were compared with results derived from active sampling using Carbograph 1TD and silicagel coated with 2,4-dinitrophenylhydrazine cartridges, based on previously validated methods. The identification and quantification of organic compounds was performed using gas chromatography with flame ionisation coupled with a mass spectrometer after thermal desorption. Aldehydes were determined by means of high-performance liquid chromatography. In the present study, the results obtained with the use of active and passive methods of air sampling were compared, correlations between the two sampling methods were designated and the repeatability of passive sampling was detailed.

In present work results of researches on influence of temperature on air quality inside vehicle are presented. One new car was tested in different atmospheric conditions, after conditioning in climate chamber. Air quality was evaluated on the basis of detected volatile organic compounds (VOC) and calculated as toluene equivalent. Samples were collected onto solid sorbents and examined, after thermal desorption, with the use of gas chromatography (GC) method with flame ionisation (FID) and mass spectrometry (MSD) detectors.
