The emissions of gasoline and diesel engines contribute significantly to ever increasing pollution of living environment. A specific part of exhaust gases is composed of carcinogenic derivatives of polycyclic aromatic hydrocarbons. Amino derivatives of parent hydrocarbon fluorene, namely 2-aminofluorene (2-AF) and 2,7-diaminofluorene (2,7-DAF), are well-known hazardous air and water pollutants ...

Studies on the characteristics of hazardous air pollutants (HAPs) in emissions medium-duty diesel trucks are significantly insufficient compared to those heavy-duty trucks. This study investigated regulated and HAPs, such as volatile organic compounds (VOCs), aldehydes, polycyclic aromatic hydrocarbons (PAHs), estimated non-methane hydrocarbon (NMHC) speciation Ten conforming Euros 5 6 were tes...

The mapping of air quality over the city of Strasbourg and its vicinity requires an increase of the number of measurements aiming at spatializing information about air pollutants concentrations. A methodology based on a multisource approach for mapping air pollutants concentrations over the city was presented in previous communications. One step of the methodology is the estimation of pollutant...

Asthma is a respiratory disease whose prevalence has been increasing since the mid 1970s and that affects more than 14.6 million residents of the United States. Environmental triggers of asthma include air pollutants that are respiratory irritants. Air toxics emitted into the ambient air are listed in the 1990 Clean Air Act Amendments as hazardous air pollutants (HAPs) if they can adversely aff...
