The 2006–2007 wildfire period was one of the most extensive and long lasting fires in Australian history with high levels of fine particulate matter (PM2.5). Large populations were exposed to smoke for over 2 months. The study aimed to investigate the association between wildfire‐related PM2.5 exposure and emergency department (ED) visits for asthma. 

Exposure to fine particulate matter (PM2.5) during landscape fire events and the risk of cardiorespiratory emergency department attendances: a time-series study in Perth, Western Australia

Exposure to PM 2.5 concentrations during LFs was associated with an increased risk of all-cause EDA, overall EDA cardiovascular diseases, acute respiratory tract infections and transient ischaemic attacks.

Health impacts of bushfire smoke exposure in Australia

The existing Australian evidence base is identified and suggestions for future research are made on how to deal with smoke exposure from bushfires are discussed.

Cardiopulmonary Effects of Fine Particulate Matter Exposure among Older Adults, during Wildfire and Non-Wildfire Periods, in the United States 2008–2010

Exposure to PM2.5, on all days and locations, was associated with increased hospitalizations on smoke and non-smoke days using modeled exposure metrics, whereas risk for asthma-related hospitalizations was higher during smoke days.

Meteorological controls on atmospheric particulate pollution during hazard reduction burns

Abstract. Internationally, severe wildfires are an escalating problem likely to worsen given projected changes to climate. Hazard reduction burns (HRBs) are used to suppress wildfire occurrences, but

A positive trend in 98th quantile PM2.5 is found in the Northwest United States, due to wildfire activity and was supported by positive trends in total carbon and no trend in sulfate across the Northwest, which supports model predictions of increasing wildfire occurrence and PM1.5 in a warming world.

Wildfire particulate matter in Shasta County, California and respiratory and circulatory disease-related emergency department visits and mortality, 2013–2018

The health effects of California’s 2018 Carr Fire and preceding wildfire seasons in Shasta County are evaluated to evaluate their health effects, particularly in highly exposed populations.

Particulate matter and emergency visits for asthma: a time-series study of their association in the presence and absence of wildfire smoke in Reno, Nevada, 2013–2018

It is suggested that wildfire PM is more hazardous than non-wildfire PM for patients with asthma on days when wildfire smoke was present.

Sustained Effects on Lung Function in Community Members Following Exposure to Hazardous PM2.5 Levels from Wildfire Smoke

It is suggested that wildfire smoke can have long-lasting effects on human health and as wildfires continue to increase both here and globally, understanding the health implications is vital to understanding the respiratory impacts of these events as well as developing public health strategies to mitigate the effects.

Impacts of fire smoke plumes on regional air quality, 2006–2013

Fire smoke substantially affects regional air quality and accounts for a disproportionate number of unhealthy days and the magnitude of effects varied by location, but the largest impacts were observed across the southeast.

Intense and prolonged PM2.5 exposure during the 2019/2020 bushfires was associated with acute and persistent symptoms among people with severe asthma and monoclonal antibody use for asthma was associatedwith a reduced risk of persistent symptoms.



California Wildfires of 2008: Coarse and Fine Particulate Matter Toxicity

Concentrations of PM were not only higher during the wildfire episodes, but the PM was much more toxic to the lung on an equal weight basis than was PM collected from normal ambient air in the region.

The effects of bushfire smoke on respiratory health

During bushfire smoke episodes, PM concentrations are usually much higher than urban background concentrations, at which effects on respiratory health have been observed.

The relationship of respiratory and cardiovascular hospital admissions to the southern California wildfires of 2003

Wildfire-related PM2.5 led to increased respiratory hospital admissions, especially asthma, suggesting that better preventive measures are required to reduce morbidity among vulnerable populations.

Peat Bog Wildfire Smoke Exposure in Rural North Carolina Is Associated with Cardiopulmonary Emergency Department Visits Assessed through Syndromic Surveillance

This is the first study to demonstrate both respiratory and cardiac effects after brief exposure to peat wildfire smoke in rural counties with sparse air-quality monitoring.

A case‐crossover analysis of traffic‐related air pollution and emergency department presentations for asthma in Perth, Western Australia

Whether changes in 24‐hour average background ozone (O3), nitrogen dioxide (NO2), carbon monoxide (CO) and particulates < 10 μm (PM10) increase the risk of hospital emergency department presentations for asthma among children among children is investigated.

Implications for Community Health from Exposure to Bushfire Air Toxics

Elevated levels of respirable particles are likely to be the major cause of the higher number of hospital visits and admissions for respiratory and/or cardiovascular treatment, increased mortality, and elevated respiratory-related symptoms that were observed in communities after major bushfire events.

Impact of the 2002 Canadian forest fires on particulate matter air quality in Baltimore city.

The transport and monitoring results consistently identified a forest fire related PM episode in Baltimore that occurred the first weekend of July 2002 and resulted in as much as a 30-fold increase in ambientfine PM.

Long- and Short-Term Exposure to PM2.5 and Mortality: Using Novel Exposure Models

A novel exposure model combining satellite aerosol optical depth and land-use data to investigate both the long- and short-term effects of PM2.5 exposures on population mortality in Massachusetts, United States, for the years 2000–2008 is presented.

Measures of forest fire smoke exposure and their associations with respiratory health outcomes

Studies with varied approaches to exposure assessment and varied measures of respiratory outcomes were consistent among themselves, and consistent with most previous work.
