Pollutant emissions need to be accurately estimated to ensure that air quality plans are
designed and implemented appropriately. Emission factors (EFs) are empirical functional …

Traffic-related emissions represent a major component of airborne pollution. Historically,
dynamometer testing has been most widely used to estimate vehicle emission rates, and …

This paper discusses the development and validation of passenger car emission factors,
using real world operation data. In total, six passenger cars of different technologies were …

Ammonia (NH3) is classified as a toxic air pollutant but its release from vehicles is not
regulated. Herein we report on the efficiency of the catalytic reduction of nitrogen monoxide …

Excess nitrogen (N) is a serious water-quality problem in most of the estuaries in the United
States, especially those downstream of developed coastal basins. Understanding sources of …

Vehicular emissions of reactive nitrogen compounds (RNCs) such as nitric oxide (NO),
nitrogen dioxide (NO2), and ammonia (NH3) have a substantial impact on urban air quality …

An in situ field experiment was conducted in a highway road tunnel in the Taipei City to
determine the motor vehicle emission factors (EF) of different kinds of air pollution species …

Long-term air quality measurements from a roadside monitoring site of the Swiss national air
pollution-monitoring network (NABEL) are analysed for average real-world road traffic …

Traffic-induced emissions are a major source of air pollutants, particularly in urban areas.
Adequate characterization and quantification of the contribution of this source depend to a …

Emission factors (EF) of volatile hydrocarbons, oxygenated organics, polycyclic aromatic
hydrocarbons (PAH) and sulfur dioxide measured in a road tunnel study (Gubrist tunnel …
