(Another Air Alert in Calexico)….It was issued Sunday morning.
The Air Pollution Control District says the Air Quality Index at the Ethel Street monitoring station reached very high levels of PM 2.5, for a Condition of Unhealthy Air Quality for Sensitive Groups. The Sensitive, or At Risk groups for this condition are those with Heart or Respiratory disease, the elderly and the very young. It is recommended those in the Sensitive groups reduce physical activity, or remain indoors until the levels of PM 2.5 lower. PM 2.5 is a finite particulate matter created mostly from vehicle emissions. Calexico is the only area that experiences high levels of PM 2.5.
