Correlating Particulate Matter Mobile Source Emissions to Ambient Air Quality
نویسندگان
چکیده
This paper describes the work and results of the second phase of research sponsored by the Federal Highway Administration (FHWA) initiated to study the relationship between traffic activity and ambient PM2.5 concentrations. The study, entitled “Estimating the Transportation Contribution to Particulate Matter Pollution”, had the objective of performing a correlation analyses on particulate matter (PM) and traffic monitoring data collected in several metropolitan areas. This effort is a cooperative initiative between the FHWA, the Environmental Protection Agency (EPA), state Departments of Transportation (DOTs), and, in some cases, local transportation agencies. The study approach linked EPA monitoring initiatives with the traffic data collected by state and/or local transportation agencies to evaluate mobile source emission contributions to ambient PM concentrations.

Methods of characterizing the distribution of exhaust emissions from light-duty, gasoline-powered motor vehicles in the U.S. fleet.
Mobile sources significantly contribute to ambient concentrations of airborne particulate matter (PM). Source apportionment studies for PM10 (PM < or = 10 microm in aerodynamic diameter) and PM2.5 (PM < or = 2.5 microm in aerodynamic diameter) indicate that mobile sources can be responsible for over half of the ambient PM measured in an urban area. Recent source apportionment studies attempted ...

Two experimental monitoring campaigns were carried out in 2012 to investigate the air quality in the port of Naples, the most important in southern Italy for traffic of passengers and one of the most important for goods. Therefore, it represents an important air pollution source located close to the city of Naples. The concentrations of sulfur dioxide (SO₂), nitrogen dioxide (NO₂), and BTEX (be...

Air quality is an important determinant of public health and quality of life. A secondary data analysis was carried out to investigate trends and air quality in Virginia. The analysis included an evaluation of two major air pollution source categories, emission of criteria and hazardous air pollutants, ambient concentrations of criteria pollutants, ozone standard violations and associated meteo...
متن کاملThe contribution of motor vehicle emissions to ambient fine particulate matter public health impacts in New York City: a health burden assessment
BACKGROUND On-road vehicles are an important source of fine particulate matter (PM2.5) in cities, but spatially varying traffic emissions and vulnerable populations make it difficult to assess impacts to inform policy and the public. METHODS We estimated PM2.5-attributable mortality and morbidity from on-road vehicle generated air pollution in the New York City (NYC) region using high-spatial...

The control of particulate matter emissions from cotton gins is a priority in many states. The air pollution regulatory process requires that concentrations measured off-property be less than the National Ambient Air Quality Standards. Two methods are commonly used to determine the concentrations on or beyond the property line: ambient sampling and dispersion modeling. In order to limit the emi...
