This study was designed to estimate and compare the air pollution exposures experienced
by commuters in six common transportation modes utilized by California residents, and to …

Personal exposure to ultrafine particles (UFP) can occur while people are cooking, driving,
smoking, operating small appliances such as hair dryers, or eating out in restaurants. These …

Concentrations of air pollutants from vehicles are elevated along roadways, indicating that
human exposure in transportation microenvironments may not be adequately characterized …

ABSTRACT Globally, 1.3 billion on-road vehicles consume 79 quadrillion BTU of energy,
mostly gasoline and diesel fuels, emit 5.7 gigatonnes of CO2, and emit other pollutants to …

Vehicle emissions are identified as a major source of air pollution in metropolitan areas.
Emission control programs in many cities have been implemented as part of larger scale …

Monitoring street-level particulates is essential to air quality management but challenging in
high-density Hong Kong due to limitations in local monitoring network and the complexities …

Urban air pollution is quite complex and exhibits significant spatial variability within
communities. Traditional centralized monitoring captures temporal variability as well as the …

Accurate quantification of exposures to traffic-related air pollution in near-highway
neighborhoods is challenging due to the high degree of spatial and temporal variation of …

Recent studies have suggested that exposures during traffic participation may be associated
with adverse health effects. Traffic participation involves relatively short but high exposures …

Abstract Particulate matter that< 2.5 µm in aerodynamic diameter (PM 2.5) has been
recognized as one of the principal pollutants that degrades air quality and increases health …
