(Heat and Air Pollution)…That is what they are dealing with in Calexico.

Temperatures began to rise Saturday, and so did levels of PM 2.5. The Air Pollution Control District issued an Air Quality Alert at 1:00 Saturday afternoon due to high levels of the Particulate Matter. Another Alert was issued at noon Saturday afternoon. The latest Air Quality Alert was issued at 7:00 Monday morning. Air Quality in Calexico beginning Saturday was listed as Unhealthy for Sensitive Groups. People in the Sensitive Groups are those with respiratory of heart disease, the elderly and children. Those in the Sensitive group are being advised to stay indoors and avoid heavy exertion as much as possible until the levels of PM 2.5 are lower. PM 2.5 is a finite particulate matter, created mostly from Vehicle Exhaust. The long lines crossing the border are being blamed for the high levels of PM 2.5.
