The stagnant hot and humid airmass over the Northeast United States will contribute to moderate to unhealthy concentrations of ground level ozone in Southern New England on Saturday, July 20, 2013. The hot stretch and poor air quality will end Saturday night when a cold front sweeps through and brings a cleaner, slightly cooler airmass from Canada.
The following information is from the RI DEM website

HEALTH EFFECTS
| Rating | Adverse Health Effects | Ways to Protect Your Health |
|---|---|---|
| Good | None expected | No precautions necessary |
| Moderate | Ozone levels in this range may cause respiratory problems in some children and adults engaged in outdoor activities. These effects are of particular concern for those with existing lung problems. | People with respiratory diseases such as asthma and other sensitive individuals should consider limiting outdoor exercise and strenuous activities during the afternoon and early evening hours, when ozone levels are highest. |
| Unhealthy | As ozone levels increase, both the severity of the health effects and the number of people affected increase.Health effects commonly include: coughing; eye, nose, and throat irritation; chest pain; decreased lung function; shortness of breath; increased susceptibility to respiratory infection; aggravation of asthma; and other respiratory ailments.
It is important to be aware that individuals react differently when exposed to various ozone levels in the unhealthy range; some people experience problems at lower unhealthy levels, while others may not be affected until higher levels are reached. However, certain groups are particularly sensitive to ozone in the unhealthy range, including:
|
In general, everyone should limit strenuous outdoor activity during the afternoon and early evening hours, when ozone levels are usually highest.If you find that you are particularly sensitive to ozone, or if you have asthma or other respiratory problems, stay in an area where it’s cool and, if possible, where it’s air-conditioned.
If you want to take action to minimize exposure to unhealthy ozone levels, you should consider scheduling outdoor exercise and children’s outdoor activities in the morning hours, when ozone levels are generally lower. As ozone levels increase, individuals who experience respiratory problems may wish to consult their doctors. At the highest levels – an AQI between 201 and 300, everyone should avoid being outdoors. |
