Application of proton transfer reaction mass spectrometry to measure hydrocarbon emissions in engine exhaust: Author: Rogers, Todd Michael; Date: 2007-08-15; Program: Chemistry; Abstract: Megacities around the world face air quality problems due to exhaust emissions from large vehicle fleets. Chemical reactions involving volatile organic compounds (VOC) from automobile exhaust are known to produce ground level ozone which poses a threat to human health and plant life. Additionally, some of these organic compounds are known carcinogens. While the dangers of VOC are well known, their production from in use vehicles and aircraft are relatively poorly understood.
