Indoor/Ambient Residential Air Toxics Results in Rural Western Montana
… organic compounds (including 14 hazardous air pollutants) were measured in the homes of nearly 80 western Montana (Missoula) high school students as part of the ‘Air Toxics Under the Big Sky’ program during the 2004/2005 and 2005/2006 school years. Target analytes were measured using low …

Human Health Risk Assessment for Petroleum Refining Industry of the Remaining Air Toxics after MACT I Emissions Reductions
Inhalation risks on human health for hazardous air pollutants emitted from MACT I petroleum refining industry were determined using EPA HEM-3 Program. Methodology included compiling vertical and fugitive emissions from 2002 National Emissions Inventory for sources inside two facilities in …

EXPLORING RISK ASSESSMENT METHODS TO EXAMINE NEUROLOGICAL RISK DUE TO AIR TOXIC EXPOSURE IN MINNESOTA
… between sociodemographic characteristics and air toxic exposure in the United States. However, a few studies have examined the neurological risk from exposure to air toxics. The purpose of the study was to determine the correlation between sociodemographic variables and neurological risk due …

Intraurban Spatiotemporal Variability of Ambient Air Pollutants across Metropolitan St. Louis
<p>Ambient air monitoring networks have been established in the United States since the 1970s to comply with the Clean Air Act. The monitoring networks are primarily used to determine compliance but also provide substantive support to air quality management and air quality research including …

Atmospheric volatile organic compound measurements: Distributions and effects on air quality in coastal marine, rural and remote continental environments
… of the analytical methods employed for whole air sampling and analysis of atmospheric volatile organic compounds is presented. The system described in this thesis produced high precision measurements for a large suite of nonmethane hydrocarbons, halocarbons, and alkyl nitrates, from part per …

Application of a Mobile Flux Lab for the Atmospheric Measurement of Emissions (FLAME)
According to the World Health Organization, urban air pollution is a high public health priority due its linkage to cardio-pulmonary disease and association with increased mortality and morbidity (1, 2). Additionally, air pollution impacts climate change, visibility, and ecosystem health. The …

Characterization of Risk From Airborne Benzene Exposure in the State of Florida
Environmental airborne benzene is a ubiquitous hazardous air pollutant whose emissions are generated from multiple sources, including industrial emissions, fuel station emissions, and automobile emissions. Chronic occupational exposures to elevated levels of benzene are known to be associated with …

Adsorption Thermodynamics and Mass Transfer of Toxic Volatile Organic Compounds in Activated -Carbon Fiber -Cloth for Air Pollution Control
… compounds (TVOCs) constitute 69% of the total air toxics emitted by major industrial point sources. Adsorption is one of the most practical mechanisms that can be used to separate and recover TVOCs before they are discharged into the atmosphere. Research on new adsorbent materials and …

Quantifying the health and economic impacts of mercury : an integrated assessment approach
… used to evaluate the benefits of the Mercury and Air Toxics Standards-a recent US regulation that targets emissions from coal-fired power plants-until 2050. I estimate the annual benefit of MATS to be 13 million 2005 USD, compared to a scenario that includes stringent air quality policy, and 414 …

The Spatial Relationships among Neurotoxicant Exposure, Child Admissions, and Mental Health Assessment Scores: How do they Interact in the State of Ohio?
… neurological toxicants were released into the air and water of the United States. Ohio had the dubious distinction of being one of the worst offenders because it was in the top-five emitters nationally (U.S. EPA, 2009a). While environmental toxicants are harmful to everyone, children are …

Potential for City Parks to Reduce Exposure to Hazardous Air Pollutants
… ethylbenzene, and xylenes (BTEX) are hazardous air pollutants commonly found in outdoor air. Several studies have explored the potential of vegetation to mitigate BTEX in outdoor air, but they are limited to a northern temperate climate and present conflicting results. To investigate this issue …
