NORTHRIDGE-CHATSWORTH, CA — The South Coast Air Quality Management District predicts that air quality will be in the moderate to unhealthy range in the San Fernando Valley on Monday.

The forecast released by the AQMD states that air quality could be in the unhealthy range for people who are sensitive to air pollution.

The Air Quality Index measures the amount of pollutants in the air, whether ozone, carbon monoxide, nitrogen dioxide, PM2.5 (particulate matter 2.5 micrometers or less in diameter) or PM10 (particulate matter 10 micrometers or less in diameter).

Air quality is designated “unhealthy for sensitive groups” when AQI levels are from 101 to 150. At this level, active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.
