E-book Wildfire Smoke : A Guide for Public Health Officials
Wildfire smoke events can occur without warning – but we can be prepared. This Guide is intended to provide state, tribal, and local public health officials with information they need to be prepared for smoke events and, when wildfire smoke is present, to communicate health risks and take measures to protect the public. Although developed for public health officials, the information in this document could be useful to many other groups including health professionals, air quality officials, and members of the public. The document is divided into five Chapters and five Appendices. Guide authors and contributors will post up-to-date guidance, documents, and other new evidence based information here between revisions for use by public health officials. Wildfire smoke is a mixture of air pollutants of which particulate matter is the principal public health threat. The initial basis for understanding wildfire smoke health effects was derived primarily from studies of ambient air pollutants, specifically particulate matter. Extensive scientific evidence has demonstrated health effects in response to shortterm (i.e., daily) particulate matter exposure ranging from eye and respiratory tract irritation to more serious effects, including reduced lung function, pulmonary inflammation, bronchitis, exacerbation of asthma and other lung diseases, exacerbation of cardiovascular diseases, such as heart failure, and even premature death. Recent studies examining the health effects of wildfire smoke provide evidence of health effects consistent with those reported for particulate matter. However, there is only limited evidence about the potential health impacts due to cumulative exposures from repeated, multi-day wildfire smoke exposures or multiple, consecutive fire seasons.
