Calexico Air Quality unhealthy for some overnight

(Calexico Air Quality affected, again)….Again, it was high levels of PM 2.5.

The Air Pollution Control District issued an Air Alert at 10:00 pm Wednesday night. The Alert was for high levels of PM 2.5, a finite Particulate Matter, created mostly from vehicle emissions. The high levels resulted in an air quality condition of Unhealthy for Sensitive groups. By 6:00 am Thursday the levels had reduced to an air quality condition of Good. The high PM 2.5 levels in Calexico are attributed in most part by the long lines to cross the border and heavy traffic in Mexicali.
