(Davis, CA) – The Yolo-Solano Air Quality Management District is issuing an Air Quality Advisory for Tuesday, Oct. 10, to notify residents of air quality conditions in the District. The Advisory includes smoke from multiple wildfires occurring in neighboring counties that have been transporting smoke into the District due to winds and wind direction.

Air quality in the District for PM has reached Moderate in Davis, Woodland, Rio Vista, Dixon and West Sacramento and Unhealthy (for everyone) in Vacaville, which reached an AQI of 194 at 6 a.m. Tuesday morning. Continuing wind conditions and wildfires today may prolong impacts to local communities and residents who might smell smoke and/or experience a range of health issues from coughing and trouble breathing to headaches and chest pain.

“Wildfire smoke is especially harmful because of PM2.5 (Particulate Matter),” said the District’s Air Pollution Control Officer Mat Ehrhardt. “PM2.5 is so small, about 1/30 the width of a human hair, that it can penetrate deep into the lungs.”

Those that are sensitive to air quality or smoke impacts, such as pregnant woman, the elderly, young children and those with respiratory illnesses such as heart or lung disease and asthma should take additional precautions if necessary, such as closing windows and doors, turning on the air-conditioning, or avoiding vigorous outdoor or indoor exertion. To avoid worsening health effects of smoke, don’t use indoor or outdoor wood-burning appliances, including fireplaces. Smoke impacts can affect anyone, regardless of physical fitness, age or health.

These fires have damaged buildings and thousands of homes with evacuations in effect for multiple locations.
