The hot and humid air which is in place over the Washington, D.C. area plus the lack of strong wind, lots of sunlight and normal workday traffic is going to create some real bad pollutants for our area over the next couple of days. This cocktail is going to cause a Code Orange Air Quality Alert, the first of 2013.
A Code Orange Air Quality Alert means that air pollution concentrations in our region may become unhealthy for sensitive groups, which include the elderly, children and people suffering from asthma, heart disease or other lung diseases.
The effects of air pollution can be minimized by avoiding strenuous activity or exercise outdoors.
Air quality in our has improved in the region over the years thanks to pollution controls. The number of combined code orange and red days has declined markedly since the mid-1990s according to an American Lung Association report.
