Long lines coming across the border is creating high levels of PM 2.5, a finite particulate matter mostly from vehicle emissions.  The Air Pollution Control District began issuing Air Alerts for the Calexico area over the weekend. At mid-morning Monday air quality in Calexico was listed as Unhealthy for Sensitive Groups. Those most at risk are those with respiratory or heart disease, the elderly and children. It is recommended those in the Sensitive groups avoid heavy or prolonged exertion, and stay indoors as much as possible until the levels of PM 2.5 are lower.
