An air quality alert for Long Island, citing expected high ozone levels, is in effect for Wednesday from 11 a.m. to 11 p.m., issued by the state Department of Environmental Conservation.

The air quality index value is expected to be greater than 100 for the pollutant ozone, with the higher the index level, the greater the health concern, the National Weather Service’s Upton office said on its website.

The very young and those with respiratory problems, such as asthma or heart disease, may be especially sensitive to the elevated levels.
