About Coarse Particulate Matter
Particles between 2.5 and 10 micrometers, including dust, pollen, and mold.
Measured in µg/m³
Health Impact
Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
Active children and adults, and people with respiratory disease, such as asthma, should avoid prolonged outdoor exertion; everyone else, especially children, should limit prolonged outdoor exertion.
What Is a Safe Level of PM10?
By the EPA Air Quality Index, coarse particulate matter is Good — safe for everyone up to 54 µg/m³ (AQI 0–50). From 54 to 154 µg/m³ is Moderate (AQI 51–100): acceptable for most people, though unusually sensitive individuals may notice symptoms. Above 154 µg/m³ the air turns Unhealthy for Sensitive Groups and EPA health guidance applies.
Riverside is currently at AQI 53 (≈59 µg/m³, estimated) for PM10 — in the Moderate range, which is acceptable for most people but worth watching if you're in a sensitive group.
Thresholds are the official EPA AQI category breakpoints for coarse particulate matter. The current concentration is estimated from the measured AQI sub-index; the exact value within a band is not recoverable from the index alone.
