Isoprene from expired air inside a private car.
The concentration of isoprene inside a small-sized parked private car with one person was found to be of the order of 20 micrograms/m3. Isoprene was then the major non-methane volatile hydrocarbon except in strongly traffic-polluted parking places. On driving, with intermediate fan ventilation, the isoprene levels were one order of magnitude lower. In the empty car, the concentrations were stil...
متن کاملPentane and isoprene in expired air from humans: gas-chromatographic analysis of single breath.
Both pentane and isoprene are excreted in human breath. Although pentane is considered an index of lipid peroxidation, the significance of isoprene is unknown. Having a similar boiling point, these two hydrocarbons are difficult to separate by gas chromatography. We separated pentane from isoprene on both a Poraplot Q and a Poraplot U column, injecting single-breath samples directly into a gas ...

متن کاملSubjective Preference for Air-Conditioner Sounds inside A Car In Summer and Winter
The sound quality inside a car is a very important aspect of automobile design. Many different sources produce sounds that can be heard inside a car. Previous studies have investigated the sound quality of the sources, such as those produced by the engine [1,2], door closing [3,4], and power windows [5,6]. Recent developments in vehicle design have led to a reduction in various sound levels, pr...
متن کاملA simple method of carbon dioxide estimation in expired air.
A SIMPLE method for the estimation of carbon dioxide in air or gas mixtures containing anaesthetic gases finds many applications in the investigation of anaesthetic problems and in the control of artificial respiration by mechanical respirators. This adaptation of already established techniques utilizes apparatus which may be found in most hospitals. It is rapid, and can be performed at the bed...
