Unhealthy air redux: You know the routine

Unhealthy air quality's coming -- one more time.

That's the recipe for tomorrow as we get ready to stew again, though overall temperatures are forecast to be lower and there's a chance of thunderstorms. The likelihood of thunderstorms increases tomorrow night.

For tonight, fog is in the forecast and there could be areas of fog before 9 a.m. tomorrow, according to the National Weather Service in Taunton, Mass.

The Department of Environmental Management predicts air quality will approach unhealthy levels, the same prediction over the past couple of days.

It means tomorrow will bring more free RIPTA routes, aside from special services.

The poor air expected tomorrow is due to high levels of fine particles in the ambient air, the DEM said in a news release. Fine particles are produced by many natural and manmade sources, including factories, power plants, motor vehicles, fires and windblown dust.

The state Department of Health warns that short-term exposure to elevated levels of fine particles can cause irritation of the eyes, nose and throat, coughing, chest tightness and shortness of breath. Short-term exposures also can aggravate symptoms of asthma and bronchitis and can increase susceptibility to respiratory infections.

For people with heart disease, short-term exposure to elevated levels raises risk of heart attacks and arrhythmias, DEM said.

"Long-term exposures can cause decreased lung function, chronic respiratory disease and even premature death," the DEM said.

People with heart or lung disease, older adults and children are more sensitive to the effects of breathing this stuff.
