Code Orange air quality in Richmond as of 3:00 pm, June 5th

Code Orange air quality in Richmond as of 3:00 pm, June 5th.

As of 3:00 pm, Thursday, June 5th, the estimated Air Quality Index (AQI) in the Richmond area based upon current ground-level ozone concentrations is in the Code Orange range. Active children and adults, and people with respiratory diseases, such as asthma, should limit strenuous outdoor activities through this evening.

In addition, the air quality forecast for Friday, June 6th for Richmond is Code Orange - Unhealthy for Sensitive Groups air quality. Active children and adults, and people with respiratory diseases, such as asthma, should limit strenuous outdoor activities tomorrow afternoon through tomorrow evening. The Virginia Department of Environmental Quality (DEQ) expects similar air quality conditions to continue through the upcoming weekend.

DEQ recommends that people take these voluntary steps:
-- Avoid unnecessary car trips. Combine errands.
-- Share a ride or use public transportation.
-- Limit or halt use of gasoline-powered lawn equipment and solvents.
-- Avoid excessive engine idling.
-- Telecommute.
-- Conserve electricity.
-- Avoid burning yard debris or brush.

Note: Recent health studies have shown that adverse health effects for ozone can happen at lower levels than previously thought. Consequently, the ozone concentrations that go into the AQI calculation have been adjusted. Ozone concentrations that had yielded a 79 AQI (Code Yellow) will now yield a 101 AQI (Code Orange). The effect of the new AQI will be an increase in the AQI forecast along with a corresponding increase in the number of Code Orange and possibly Code Red forecasts.
