Background: Large wildfires are increasing in frequency and contribute substantially to the air quality across the United States. Smoke Sense is an initiative that aims to understand the health effects of wildfire smoke exposure and evaluate effective forms of communication. The...

Until recently, most wildfire air quality impacts were determined by permanent stationary regulatory monitors that are used to calculate the Air Quality Index (AQI). Low-cost particulate matter (PM) sensors have found widespread use by the public in smoke impacted areas but have ...

The American Lung Association is sponsoring a webinar titled &ldquo;Protecting Lung Health During the Wildfire Season&rdquo; which will focus on Western US states who are presently be impacted by nearly 100 wildfires. Within the broader webinar Dr. Wayne Cascio will make a presen...

Wildland fires are diminishing air quality on a seasonal and regional basis, raising concerns about respiratory health risks to the public and occupational groups. This American Thoracic Society (ATS) workshop was convened to meet the growing health threat of wildland fire smoke....

Objectives: California plans to substantially increase the use of prescribed fire to reduce risk of catastrophic wildfires. Although for a beneficial purpose, prescribed fire smoke may still pose a health concern, especially among sensitive populations. We sought to understand co...

Startling images of smoke-filled skies have filled the news and social media in recent years during major wildfires in the U.S. (Figure 1). In 2020, over 10 million acres burned from nearly 59,000 wildland fires, including wildfires and prescribed fires (National Interagency Coor...

Wildland fires are one of the largest sources of emissions to the atmosphere in the United States causing extended, and occasionally extreme, smoke episodes in many parts of the country. Wildland fires have increased in magnitude over the past decade, burning millions of acres of...

Air pollutant concentrations near major highways are usually attributed to a combination of nearby traffic emissions and regional background, and generally presumed to be additive in nature. During a recent year-long near-road monitoring study conducted in Las Vegas, NV, a substa...

Wildfires have increased dramatically over the past decade in extent and severity, with unprecedented adverse impacts on the wellbeing of humans and the environment. The US Southeast, with its rapidly changing economy and demographics, is a region where both climate and socioecon...

Wildland fire emits a substantial quantity of aerosol to the atmosphere. These aerosols typically comprise a complex mixture of organic matter and refractory elemental or black carbon with a relatively minor contribution of inorganic matter from soils and plant micronutrients. Id...

This research was completed during the authors' previous position at Duke University prior to August 2020. Exposure to pollution from wildland fires (wildfires; bushfires) contributes significantly to poor air quality, a leading risk factor for premature death. The frequency and ...

Rationale: Epidemiological studies have shown associations between the incidence of increased emergency room admissions, hospital and outpatient clinic visits for respiratory causes with the exposures to wood stove, wildfires, and other forms of organic mass burning. In June 2008...

Emissions Research for the National Emissions Inventory &ndash; 2017 NEI and Beyond Objective: Improve science of emissions sources that are associated with natural and physical processes in the environment. Include these improved emissions in the National Emissions Inventory (N...

Background: The effects of exposure to fine particulate matter (PM2.5) during wildland fires are not well understood in comparison to PM2.5 exposures from other sources. Objectives: We examined the cardiopulmonary effects of short-term exposure to PM2.5 on smoke days and evaluat...

This presentation will provide an overview of recent research on causal modeling concepts with Bayesian networks at a Pacific Ecological Systems Division seminar series for wildfires. mistry. He is currently a Research Toxicologist in EPA’s Office of Research and Development in G...

Wildland fires emit high concentrations of airborne particulate matter (PM) and volatile organic compounds which can impact sensitive populations such as asthmatics. Health effects of these biomass emissions may vary significantly depending on fuel type and burn conditions. We as...

National Academies of Sciences, Engineering, and Medicine. Wildland Fires: Towards Improved Understanding and Forecasting of Air Quality Impacts &ndash; A Workshop

This chapter assesses the current state of the science regarding the composition, intensity, and drivers of wildland fire emissions in the USA and Canada. Globally and in the USA wildland fires are a major source of gases and aerosols which have significant air quality impacts an...

Fires that occur in the wildland urban interface (WUI) often burn structures, vehicles, and the items contained within them as well as biomass in the natural landscape. Because these fires often burn near population centers, their emissions may have a sizeable impact on public he...

Biomass burning from wildfires, prescribed fires, grasslands, rangelands, and crop residue is an important contributor to the degradation of air quality because of its impact on ozone and particulate matter. During the past several years, there have been several updates and revis...

The area burned by wildland fires (prescribed and wild) across the contiguous United States has expanded by nearly 50% over the past 20 years, now averaging 5 million hectares per year. Chemical transport models are used by environmental decision makers to both examine the impact...

This presentation is part of the &ldquo;Ecological, Human Health, Economic and Social Impacts of Wildland Fires&rdquo; session. This presentation will highlight the health impacts of wildland fire smoke exposure, and the various facets of ORD&rsquo;s wildland fire and health rese...

Wildland fires are a major source of fine particulate matter (PM2.5), one of the most harmful ambient pollutants for human health globally. Within the U.S., wildland fires can account for more than 30% of total annual PM2.5 emissions. In order to represent the influence of fire e...
