The Tehama County Air Pollution Control District and the Tehama County Health Services Agency-Public Health is issuing an Air Quality Advisory about wildfire smoke impacts in Tehama County due to the Green Fire. Conditions throughout Tehama County will likely vary from “Moderate” to “Unhealthy” as smoke from wildfires drifts over the area.
When wildfires move into communities, they present both environmental and public health hazards. The main public health hazard is caused by small particles of toxic materials contained in the smoke that originate from the burning plastics and other chemicals. These particles are referred to as PM2.5. The reason PM 2.5 is a concern is because this size particle can cause both pulmonary and cardiovascular health problems. In addition to particulate matter, ground -level ozone can also cause inflammation in the lungs and an overall reduction in lung function.
Health related symptoms associated with smoke and ozone impacts can vary across different age groups, but in general common symptoms to look for include coughing, scratchy throat, watery and itchy eyes, headaches, and difficulty breathing. For at risk individuals, children, elderly and those with existing heart and lung disease, symptoms may also include wheezing, chest pain and fatigue.
Strategies to reduce your exposure to wildfire smoke include staying indoors, reducing outdoor physical activity, reducing indoor sources of air pollution (use of tobacco, vape devices and wood burning stoves), and changing your indoor air filters frequently. If you must go outside, consider wearing an N95 mask, especially if you are in a high-risk category.
In addition, all open burning is prohibited during this period.
