Font Size Extra Large Font Size Large Font Size Default

Particulate matter is the principal pollutant of concern in wildfire smoke for short-term exposures. The tiny particles can build up in your respiratory system causing a number of health problems including burning eyes, runny noses, and illnesses such as bronchitis. They can also aggravate other health problems.

In the event of a wildfire, go to San Diego County Emergency Home Page for the latest information.
