BOSTON -- The U.S. Environmental Protection Agency is predicting another day of unhealthy air quality for Thursday, June 26, with elevated levels of ground-level ozone (smog) predicted for southern Maine, southern New Hampshire, Massachusetts, Rhode Island, and Connecticut with the highest smog concentrations expected in southwestern Connecticut. Elevated levels of fine particles are also expected throughout New England for tomorrow which will result in hazy conditions.
Ground level ozone, the main ingredient of smog, is unhealthy when average concentrations exceed 0.08 parts per million over an eight-hour period. So far this year, there have been 3 days, including today, when ozone monitors in New England have recorded concentrations above this level. (A preliminary list of the unhealthy readings recorded so far this summer can be found at https://www.epa.gov/region01/airquality/o3exceed-03.html.)
Exposure to elevated ozone levels can cause serious breathing problems, aggravate asthma and other pre-existing lung diseases, and make people more susceptible to respiratory infection. Exposure to elevated particulate levels can increase the likelihood of respiratory symptoms in sensitive individuals, aggravate heart or lung disease and cause premature mortality in persons with cardiopulmonary disease and the elderly.
When smog levels are up, residents should refrain from strenuous outdoor activity, especially sensitive populations such as children and adults with respiratory problems. In addition, when particulate concentrations in the ambient air are elevated, people with respiratory or heart disease, the elderly, and children should limit prolonged exertion.
“The medical community speaks loudly and clearly on this issue: When ozone levels are up, New Englanders should refrain from strenuous outdoor activity, especially sensitive populations such as children and adults with respiratory problems,” said Robert W. Varney, EPA New England’s regional administrator. “Up to 20 percent of summertime respiratory-related hospital visits in New England are directly attributable to ozone.”
Ground-level ozone (smog) is formed when volatile organic compounds and oxides of nitrogen interact in the presence of sunlight. Cars, trucks and buses give off the majority of the pollution that makes smog. Fossil fuel burning at electric powerplants, particularly on hot days, give off a lot of smog-making pollution. Gasoline stations, print shops, household products like paints and cleaners, as well as lawn and garden equipment also add significantly to the ozone smog.
Major sources of particulate pollution are factories, power plants, trash incinerators, motor vehicles, construction activity, and fires.
When air quality is forecast to be unhealthy, EPA asks the public to take ozone action. You or your employer can help get rid of ozone-smog by limiting the things you do that make air pollution. For instance:
- use public transportation, or walk whenever possible;.
- if you must drive, car pool and combine trips;
- go to the gas station at night to cut down on gasoline vapors getting into the air during day light hours when the sun can cook the vapors and form ozone;
- avoid using gasoline powered engines, such as lawn mowers, chain saws, leaf blowers on unhealthy air days.
In order to help New England residents prepare for poor air quality this summer, EPA and the New England states provide real-time ozone data and air quality forecasts. The real-time air quality data and forecasts are available at www.epa.gov/ne/aqi. New at this web site this year is an interactive tool that allows individuals to access the most recent air quality index reading for ozone monitors in their area.
People can also sign up at this web address to receive smog alerts from EPA’s New England office. Smog Alert is a free service provided by EPA in conjunction with the New England states which automatically notifies you by e-mail or fax when high concentrations of ground-level ozone are predicted in your area. Smog Alerts are issued to notify interested persons of predicted poor air quality in specific geographical areas of New England throughout the smog season, May through September.
