Wildfire smoke and your health
Smoke is made up of primarily small particles, gases and water vapor, with trace amounts of hazardous air pollutants. The most harmful are the small particles, or particulate matter smaller than 2.5 micrometers in diameter (100 micrometers is the diameter of a human hair). These particles can be inhaled deeply into the lungs, damaging lung tissue and causing respiratory and cardiovascular problems.
Wildfire can be a significant source of air pollution in Oregon and can pose a major health risk. Symptoms from short-term smoke exposure can range from scratchy throat, cough, irritated sinuses, headaches, runny nose and stinging eyes. Persons with asthma, emphysema, congestive heart disease and other existing medical conditions can have more serious reactions. The elderly and children are also high-risk groups.
