The Arizona Department of Environmental Quality has issued an Ozone Health Watch for the remainder of Monday, July 8 and for Tuesday, July 9.
A health watch is issued when ozone levels may approach federal standards.
Ground level ozone is formed by a chemical reaction that needs heat from sunlight, nitrogen oxides and volatile organic compounds [VOCs] to form. It can aggravate existing health conditions like asthma.
The months of April through September make up our Valley’s longer-than-normal "ozone season."
During a health watch, the department suggests residents:
- Avoid waiting in long drive-thru lines, for example, at coffee shops, fast-food restaurants or banks. Park your car and go inside.
- Unplug unused appliances.
- Fuel your vehicle after dark or during cooler evening hours.
- Connect your outdoor lights to a timer or use solar lighting.
