The fine particulate matter baseline (PMB), which includes PM2.5 monitor readings fused with Community Multiscale Air Quality (CMAQ) model predictions, using the Hierarchical Bayesian Model (HBM), is less accurate in rural areas without monitors. To address this issue, an upgrade...

The global disease burden resulting from exposure to traffic emissions is a growing worldwide public health threat. Children&mdash;from infancy to the age of 14&mdash; are especially susceptible to the health effects of traffic emissions due to their rapidly developing immune, ne...

Ozone exposure is associated with higher risk of asthma-related emergency department visits. The meteorological conditions that govern ozone concentration are projected to be more favorable to ozone formation over much of the United States due to continued climate change, even as...

The overall objective of this study was to characterize fungal and bacterial populations in the Martin Pe&ntilde;a Channel (MPC) urban community residences in San Juan, Puerto Rico, following flooding events. The profiles presented were generated by comparing the fungal and bacte...

• Identify why wildfire smoke exposure is a public health and clinical concern. • Identify groups at greatest risk from particle pollution in wildfire smoke. • Explain how particle pollution from wildfire smoke affects the general population....

Severity of large fires has increased. Science is there: smoke produces a range of health outcomes, impacts productivity, and wellbeing. Can we construct communication strategies that deliver information when we most need it and when we perceive salience of intervention? Educa...

Acute and chronic exposures to biomass wildfire smoke pose significant health risks to firefighters and impacted communities. Susceptible populations such as asthmatics may be particularly sensitive to wildfire effects. We examined pulmonary responses to biomass smoke generated f...

VITROCELL&reg; systems permit cell exposures at the air-liquid interface (ALI); however, there are inconsistent methodologies in the literature for their operation. Some studies find that exposure to air (vehicle control) induced cytotoxicity relative to incubator controls; other...

Epidemiology studies over the past 5 decades have provided convincing evidence that air pollution exposure is associated with multiple adverse health outcomes, including increased mortality. Air pollution is a complex mixture of particles, vapors, and gases emitted from natural ...

Halogenated platinum salts can trigger the development of occupational asthma. Until recently, laboratory research into the development and manifestation of platinum hypersensitivity responses were hindered by the lack of an animal model suitable for assessing the functional con...

This presentation will summarize the past 20 years of our research in this area. The presentation will demonstrate the application of quantitative PCR in quantifying fungi/molds.

Introduction Asthma affects &gt;24 million children and adults in the United States (US). Daily fluctuations in ground level ozone are associated with higher rates of emergency department (ED) visits for exacerbation of asthma symptoms. For a given level of anthropogenic emission...

Advancements in air pollution monitoring using (satellite) remote sensing of fine particulate matter, i.e., Aerosol Optical Depth PM2.5 (AOD PM2.5), along with ground-based air quality monitors, air quality models, and Hierarchical Bayesian Models (HBMs), have been used to combin...

Advancements in air pollution monitoring using (satellite) remote sensing of fine particulate matter (i.e., Aerosol Optical Depth PM2.5 [AOD PM2.5]), along with ground-based air quality monitors and air quality models have been used together in Hierarchical Bayesian Models (HBMs)...

Numerous studies have linked exposure to traffic-emitted air pollution with increased risk for many adverse health effects including asthma, cardiovascular disease, cancer, premature mortality, birth and developmental defects, and even autism. Air quality measurements indicate t...

Summary of EPA research and resources on how green and built infrastructure affects near-road and urban air quality

To the Editor: Short-term exposure to ambient air ozone has long been recognized to have adverse respiratory effects, leading the Environmental Protection Agency (EPA) to lower the 8-hour National Ambient Air Quality Standard (NAAQS) to 70 parts per billion (ppb) in 2015 (1). Al...

To quantify the on&#8208;road PM2.5&#8208;related premature mortality at a national scale, previous approaches to estimate concentrations at a 12&#8208;km &times; 12&#8208;km or larger grid cell resolution may not fully characterize concentration hotspots that occur near roadways...

Pollen is an important environmental cause of allergic asthma episodes. Prior work has established a proof of concept for assessing projected climate change impacts on future oak pollen exposure and associated health impacts. This paper uses additional monitor data and epidemiolo...

We previously showed offspring from Long-Evans rat dams given a high-fat diet (HFD) before, during, and after pregnancy had increased pulmonary and metabolic responses to acute ozone exposure. Increased susceptibility to allergy and asthma may also result from maternal HFD consum...

We examined influences of asthma and household environment (passive smoking, gas stove use, and having a dog or cat), on seven measures of spirometric lung function in 8-16 yearold subjects, as measured in the Third National Health and Nutrition Examination Survey (NHANES III). ...

As of 2014, approximately 7.4% of U.S. adults had current asthma. The etiology of asthma is complex, involving genetics, behavior, and environmental factors. To explore the association between cumulative environmental quality and asthma prevalence in U.S. adults, we linked the U....

The US Environmental Protection Agency (EPA) is interested in the interplay of environmental and genetic factors on the development and exacerbation of asthma. The Mechanistic Indicators of Childhood Asthma (MICA) study will use exposure measurements and markers of environmental ...

Characterizing cumulative risk and understanding the complex relationships between environmental exposures and human health outcomes requires collection and analysis of a wide range of data. Information on the characteristics of multiple stressors (chemical, physical, biological...

Indoor-mold exposure has been associated with an increased risk of asthma and respiratory illness. This study investigated respiratory illness, asthma and indoor mold contamination in two low-income, Hispanic communities, Mecca and Coachella City, in the Eastern Coachella Valley...
