NEW YORK — An Air Quality Advisory has been issued for New York City, Long Island and the areas of western New York and the lower Hudson for Wednesday.

The advisory is in effect from 11 a.m. through 11 p.m. Wednesday.

Ozone levels are expected to exceed their normal amounts due to an increase in car exhaust and out-of-state emission sources, according to a news release.

Ozone is a ground-level pollutant that is created when summer heat combines with pollution from exhaust, power plants, consumer products and other sources.

Exposure to ozone can harm health. Side effects of breathing air containing ozone include eye irritation, chest pain, coughing and shortness of breath, increased likelihood of asthma attacks and respiratory infections and inflammation in the lungs. Ozone can also worsen conditions like bronchitis, emphysema and asthma, according to the New York State Department of Environmental Conservation.

Officials urge New Yorkers to do the following to help cut down on ozone production:

  • Use mass transit or carpool to cut down on emissions
  • Turn off all lights and appliances that aren’t being used, and use appliances during off-peak hours after 7 p.m.
  • Use fans, but if AC is necessary, set the thermostat at 78 degrees
  • Close blinds and shades to preserve the cooled air in your home
  • Set refrigerators and freezers at more energy efficient temperatures
  • Install energy efficient appliances with the Energy Star label
