On-road vehicle emissions of carbon monoxide (CO), nitrogen oxides (NO(x)), and volatile organic compounds (VOCs) during 1995-2009 in the Atlanta Metropolitan Statistical Area were estimated using the Motor Vehicle Emission Simulator (MOVES) model and data from the National Emissions Inventories and the State of Georgia. Statistically significant downward trends (computed using the nonparametri...

Using real options, we analyze the timing of implementing emission limits for a decaying pollutant when random environmental effects affect its stock. Two types of irreversibility are present: the first type results from long-term environmental damage, and the second from sunk costs in pollution abatement. We assume that social damage from pollution is a power function of the stock of pollutant...

A tunable infrared laser differential absorption spectrometer (TILDAS) has been developed to measure airpollutant emission from on-road motor vehicles. The system uses a monostatic source–detector platform and a retroreflector. It has been shown to be able to measure the emissions from individual vehicles at highway speeds. Excellent detection sensitivity is obtained with measurement precision ...

Human health, the environment, and climate are being profoundly aff ected by complex pollutant interactions in the atmosphere. Almost all human activities cause the emissions of air pollutants. Their understanding and quantifi cation is the fi rst step towards the control and mitigation of air pollution. The general aim of this paper is to summarise the fi ndings of selected Croatian and Indian...

Air quality progress in the North American megacities of Los Angeles, New York, and Mexico City is reviewed, compared, and contrasted. Enormous progress made in North America over the last 5 decades provides a template for other megacities of the world, especially in developing countries, attempting to achieve rapid economic growth without compromising air quality. While the progress to date ha...

the wide availability of data on air pollutant emissions, the knowledge already achieved on theset of chemical and photochemical reactions in the troposphere, the ability to access real time weatherconditions at the local scale that determine the transport and transformation of gases and aerosol, now make it possible to obtain credible and reliable predictions, retrospective analyses and/or fut...

Modern diesel engines should have higher pollutant emissions standards with better performance and by using split injection strategies which could optimize the air – fuel mixture, this purpose could be achieved. After achieving the successful validation between modeling and experimental results for both single and double injection strategies, for the first time and in this paper, double i...

Road transport has become by far the major source of environmental pollution and traffic congestion in urban areas. Though a lot of research has been done to investigate the functional relationship linking air quality and air pollution from transport, a further improvement in the knowing of this relationship is needed. The aim of this study was to analyze this relationship and to develop a more...

Over recent decades, there has been a clear progress across Europe towards reducing anthropogenic emissions (EEA, 2010). However, poor air quality remains an important public health issue, especially in urban environments. Airborne particulate matter (PM), tropospheric ozone (O3) and nitrogen dioxide (NO2) are the main problematic pollutants in Europe. Accurate air quality forecast system can o...
