Health and Environmental Impacts of Smoke from Vegetation Fires: A Review
Year: 2016
Smoke exposure is often an inevitable side effect of open vegetation fires (both planned and wild) and is an important public health concern. The objective of this paper is to summarize state-of-the-art knowledge on health and environmental impacts of smoke from vegetation fires, to identify research gaps, and to provide needed information to researchers, land managers, policymakers, health care workers, and the general public. The main components of vegetation fire smoke and their characterizations are identified and evaluated. Concentrations, emission ratios, and emission factors of smoke…

Wildfire smoke and public health risk
Year: 2015
Wildfire activity is predicted to increase with global climate change, resulting in longer fire seasons and larger areas burned. The emissions from fires are highly variable owing to differences in fuel, burning conditions and other external environmental factors. The smoke that is generated can impact human populations spread over vast geographical areas. Wildfire smoke is a complex mixture of pollutants that can undergo physical and chemical transformation processes during transport and can have major impacts on air quality and public health. This review looks at the main features of smoke…

Smoke management of wildfire and prescribed fire: understanding public preferences and trade-offs
Year: 2014
Smoke from forest fires is a serious and increasing land management concern. However, a paucity of information exists that is specific to public perceptions of smoke. This study used conjoint analysis, a multivariate technique, to evaluate how four situational factors (i.e., smoke origin, smoke duration, health impact, and advanced warning) influence public tolerance of smoke in the northern Rocky Mountains and south-central United States. Separate analyses were performed for subgroups, based on community type, level of fire preparedness, demographics, and smoke experience, to explore…

Research Perspectives on the Public and Fire Management: A Synthesis of Current Social Science on Eight Essential Questions
Year: 2012
As part of a Joint Fire Science Program project, a team of social scientists reviewed existing fire social science literature to develop a targeted synthesis of scientific knowledge on the following questions: 1. What is the public’s understanding of fire’s role in the ecosystem? 2. Who are trusted sources of information about fire? 3. What are the public’s views of fuels reduction methods, and how do those views vary depending on citizens’ location in the wildland-urban interface or elsewhere? 4. What is the public’s understanding of smoke effects on human health, and what shapes the public’…

Health Effects of Wildland Fire Smoke: Insight from Public Health Science Studies
Year: 2012
Due to the composition and dispersion of wildland fire smoke, particulate matter is the principal pollutant of public health concern. Effects will vary based on the source of smoke but predominantly impact local communities in the same way. Studies of the effects of PM from non-fire sources show that long-term exposure can reduce lung function and cause the development of chronic bronchitis. Short-term exposure (hours or days), typical of wildland fire events, can aggravate lung disease, leading to asthma attacks and acute bronchitis. These effects can also increase the susceptibility to…

Smoke Science Plan: The Path Forward
Year: 2012
Wildland fire managers face increasingly steep challenges to meet air quality standards while planning prescribed fire and its inevitable smoke emissions. The goals of sound fire management practices, including fuel load reduction through prescribed burning, are often challenged by the need to minimize smoke impacts on communities. Wildfires, of course, also produce smoke, so managers must constantly weigh the benefits and risks of controlled burns and their generated emissions against potential wildfires and their generated emissions and must communicate those benefits and risks to the…
