Air Quality Alert On Shoreline

Southwest wind transporting ozone into Madison, Clinton and surrounding towns

The state Department of Environmental Protection issued an air quality alert for shoreline towns yesterday.

The Air Quality Index (AQI) in Madison late Monday afternoon was 140, according to data gathered at a monitoring station at Hammonasset Beach State Park. An AQI of 0 to 50 is considered good, 51 to 100 is considered moderate, and 101 to 150 is considered unhealthy for sensitive groups, such as people with respiratory problems.

"Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion during elevated ozone events," said the state DEP. "In addition, when particulate levels are elevated, people with respiratory or heart disease, the elderly and children should limit prolonged exertion."

An air quality action day alert has been issued for southern Middlesex, southern New Haven, and southern New London counties, according to the National Weather Service.

"An air quality action day means that ozone within the region may approach or exceed unhealthy standards," the National Weather Service said. "A broad southwest wind flow is transporting ozone and ozone precursors into the state, combined with hot, humid conditions and abundant sunshine."

In New Haven, the air quality index was 172 at 4 p.m., which means that ozone levels had reached unhealthy levels. In New Haven, "active children and adults, and people with lung disease, such as asthma, should avoid prolonged or heavy exertion outdoors. Everyone else, especially children, should reduce prolonged or heavy exertion outdoors."

In New London-Groton, the AQI was 109 at 4 p.m.

The state DEP says ozone is "a colorless gas that is a major constituent of smog. This pollutant alone contributes to the majority of unhealthy air quality days in CT, as measured by the Air Quality Index (AQI). Ozone is found both at high altitude and ground level. High altitude ozone is beneficial because it shields the earth from the sun's ultraviolet radiation. Ground level ozone is harmful because it reacts with the mucus membranes of the respiratory system and causes inflammation."
