Assessment and Statistical Modeling of the Relationship Between Remotely Sensed Aerosol Optical Depth and PM2.5 in the Eastern United States

Christopher J Paciorek

2012
Research Report 167
Particulate Matter

This report describes a study to assess the ability of satellite-based measurements from National Aeronautics and Space Administration (NASA) satellites to fill spatial and temporal gaps in existing monitoring networks in the eastern United States. Dr. Paciorek and colleagues developed statistical models for integrating monitoring, satellite, and geographic information system (GIS) data to estimate monthly ambient PM2.5 concentrations and used those models to estimate monthly average PM2.5 concentrations across the eastern United States. They then developed and applied statistical methods to quantify how uncertainties in exposure estimates based on ground-level monitoring data might be reduced. This study was funded under the Walter A. Rosenblith New Investigator Award.

Communication 17 describes Phase 3A of the Advanced Collaborative Emissions Study (ACES) to test emissions and health effects of emissions from 2007- and 2010-compliant diesel engines. The Communication contains results from the characterization of exposure atmospheres by Drs. Joe Mauderly and Jake McDonald at the Lovelace Respiratory Research Institute in advance of the start of animal toxicity testing in ACES Phase 3B. It provides important background information on the emissions from one selected 2007-compliant engine and their concentrations in the animal exposure chambers.

Research Report 165
Nitrogen Oxides

This report describes a study evaluating the effects of exposure to diesel exhaust (DE) and nitrogen dioxide (NO2) on the lower airways and blood of allergic asthmatic participants. The study by Dr. Riedl and colleagues was funded as part of HEI's research program looking at diesel exhaust and other particle exposures and allergic response. The participants were exposed in random order to 100 µg/m3 diesel exhaust or 0.35 ppm nitrogen dioxide for 2 hours, with or without an allergen inhalation challenge. The investigators measured multiple physiologic and pulmonary function endpoints, including specific airway resistance, oxygen saturation, bronchial reactivity, and inflammatory and immunologic endpoints.

Assessment of the Health Impacts of Particulate Matter Characteristics

Research Report 161
Particulate Matter

This report describes a study by Dr. Michelle Bell of Yale University to evaluate the effects of exposure to components of the PM2.5 mixture on short-term morbidity and mortality, using data on 52 components of PM2.5 for 187 US counties. The report explores regional and seasonal variation in the chemical composition of PM2.5 and whether this variation affects the association between short-term exposure to PM and health effects. This study was funded under the Walter A. Rosenblith New Investigator Award.

Assessing the Impact of a Wood Stove Replacement Program on Air Quality and Children’s Health

Research Report 162
Accountability
This report describes a study evaluating a community-wide program to improve air quality in a rural mountain community (Libby, Montana) by replacing older, more polluting wood stoves with new, less polluting stoves. Over the course of 4 winters, Dr. Noonan and colleagues measured PM2.5 and markers for wood smoke outdoors, in schools, and in about 20 homes before and after stove changeout. In parallel, they tracked children's respiratory symptoms (based on parental surveys) and school absences.

Research Report 164
Particulate Matter

This report describes a study that evaluated whether exposure to fine or nano-titanium dioxide (TiO2) particles may affect cardiovascular endpoints, in particular endothelium-dependent vascular dilation. Dr. Nurkiewicz and colleagues exposed rats via inhalation to 0.5 to 20 mg/m3 TiO2 for up to 12 hours and evaluated them for vascular dilation and for markers of oxidative stress, coagulation, and inflammation. This study was funded under the Walter A. Rosenblith New Investigator Award.

This report describes a study evaluating the feasibility of studying potential changes in air quality and health associated with the London Low Emission Zone (LEZ), which went into effect in 2008 and restricts entry of older, more polluting vehicles into Greater London. Based on their earlier study of London's Congestion Charging Scheme, Dr. Kelly and colleagues conducted emissions and exposure modeling to estimate the projected effects of LEZ implementation. They also assessed the feasibility of using medical records from private practices to evaluate the relationships between exposure to traffic and indicators of respiratory and cardiovascular disease.

Air Toxics
Particulate Matter

This report describes a study that tested whether an air toxics "hot spot" existed in Camden, NJ. Dr. Lioy and colleagues evaluated ambient and personal exposures of nonsmoking residents to PM2.5, VOCs, aldehydes, and PAHs in two neighborhoods in Camden, NJ, one of which was hypothesized to be a regional air toxics "hot spot." The investigators compared concentrations of air pollutants in the two neighborhoods with each other and then with concentrations at other locations in the United States. They also assessed the effects of seasonality, contributions from mobile sources, and spatial variability.
