TL;DR: In this paper, it was found that carbon dioxide is as good an indicator of chemical air quality in an urban atmosphere as any other indicator presently used, even though it is not a toxic substance.
Abstract: Carbon dioxide as an indicator of chemical air quality, its relationship to other indices of air pollution, and its characteristics in an urban atmosphere were the points of investigation in this study. It was found that carbon dioxide is as good an indicator of chemical air quality in an urban atmosphere as any other indicator presently used. On days of high pollutant concentrations, CO2 concentrations were correspondingly high, and on days of lower pollutant concentrations, CO2 concentrations were correspondingly lower. Diurnal and seasonal variations of carbon dioxide, carbon monoxide, nitric oxide, nitrogen dioxide, and oxidant reflected this relationship. In all types of fossil fuel combustion, CO2 - together with the other products of combustion processes - is produced in a fairly standard proportion as an exhaust product. Since fossil fuel combustion products are a major source of reactants and pollutants in air pollution, CO2 can be used as an indicator of air quality even though it is not a toxic substance. The high magnitudes of CO2 concentrations found in the atmosphere, and the simplicity of CO2 measuring equipment, also help to make CO2 an attractive indicator of air quality. A projected use of CO2 in air quality analysis is presented.more » Data from a mobile CO2 unit are presented as they relate to a freeway study, a residential study and an ocean study. 34 references, 15 tables.« less

TL;DR: In this paper, the relationship of local meteorology, traffic volumes and roadside air quality is discussed, showing that the main source of air pollution in London is now road vehicle emissions.
Abstract: The main source of air pollution in London is now road vehicle emissions. In addition to meteorological conditions, traffic volume is an important factor which influences the local air pollutant concentrations to which pedestrians and road users are exposed. This paper discusses the relationship of local meteorology, traffic volumes and roadside air quality. Data from the London Borough of Southwark's roadside monitoring station, situated at a major London route (A2), has been analyzed for traffic volumes and nitrogen oxides. Data sets for the months of February and March 1995 have been employed for this study. The data analysis indicates a measurable correlation between the levels of NO and NC>2, traffic volumes and wind speed.
