AIR ALERT: NOVEMBER, 2019
FINE PARTICLE POLLUTION (PM2.5) CHRONICALLY IMPACTING THE VALLEY, TAKE PRECAUTIONS
PM2.5 are particles in the air that are so small they can bypass the body’s normal defenses and move directly into the bloodstream. Chronic exposure to PM2.5 of 12 micrograms or more (AQI of 50) is linked to the development of heart and lung diseases. When PM2.5 spikes to 35 micrograms or more (AQI of 100+), it can incite events in sensitive populations – like an asthma attack, heart attack, stroke or premature death. “Sensitive populations” include those under the age of 18, pregnant mothers, those over the age of 65, and those with a chronic lung and/or heart disease. Roughly half the population of the Valley is considered “sensitive.” Please see our “Know the Air” and “Protect Your Health” webpages under our Resources tab for more information, and contact firstname.lastname@example.org if you have any questions.
