An air quality health advisory has been issued for Long Island and New York City today for the pollutant ground-level ozone.
State officials issued the alert because ozone is expected to exceed the air quality index of 100 in the NYC metro-Long Island region. That level is considered unhealthy for sensitive groups.
Ozone is a major component of photochemical smog, which can have adverse health effects, especially for young children and people with respiratory disease, such as asthma. Strenuous outdoor activity should be avoided. The ozone advisory is in effect from 10 a.m. through 10 p.m.
