An inexpensive method to estimate CO and NOx emissions from mobile sources

Abstract CO and NO x measurements from mobile sources at two urban locations in Cordoba City, Argentina, were used to develop a very simple method to estimate emission from these sources. This development was possible because primary urban air pollution in Cordoba comes mostly from mobile sources and because a field measurement campaign was conducted by the city government during 1995–1996 that has allowed us to have a complete and valuable data bank. Air concentrations of CO, NO x as well as physical, and meteorological variables were measured at two urban sites with two monitoring stations. We compared the measured CO and NO x air concentration data with the predictions of a method that uses regression analysis to estimate the emission factor from the mobile sources. The agreement is good, considering the simplicity of the approach.
