Strategic Insights

— 1 min read

State officials have issued an updated Air Quality Health Advisory for the Long Island, New York City Metro, and Lower Hudson Valley regions due to high levels of ozone and lingering smoke from Canadian wildfires. The advisory, issued by DEC Commissioner Amanda Lefton and DOH Commissioner Dr. James McDonald, is in effect from 11 a.m. to 11 p.m. on Tuesday, August 12, 2025. The public is advised to take precautions to minimize exposure to ozone, especially those with respiratory issues.

Key Takeaways:

  • The Air Quality Health Advisory is in effect for the Long Island, New York City Metro, and Lower Hudson Valley regions, covering six counties in total.
  • Ozone levels are expected to exceed an Air Quality Index (AQI) value of 100, posing a health concern for vulnerable populations.
  • DEC and DOH issue Air Quality Health Advisories when meteorologists predict ozone levels will exceed 100 AQI, requiring residents to take precautions.
  • Automobile exhaust and out-of-state emission sources are the primary contributors to ground-level ozone, a major air pollution problem in the northeast.
  • New Yorkers are encouraged to check airnow.gov for accurate information on air quality forecasts and conditions.
  • Highly vulnerable groups, including those with cardiovascular disease and respiratory issues, should limit strenuous outdoor activity when ozone levels are high.
  • Residents can minimize ozone exposure by curtailment of automobile travel, using public transportation, and taking energy-saving steps such as turning off lights and appliances.

Statistics:

  • Ozone is a colorless gas that forms when sunlight reacts with nitrogen oxides and volatile organic compounds from automobile exhaust and industrial emissions.
  • Automobile emissions account for approximately 60% of pollution in New York City.
  • DEC and DOH issue Air Quality Health Advisories when ozone levels are expected to exceed 100 AQI, which poses a significant health threat to vulnerable populations.
  • High ozone levels can also be enhanced by wildfire smoke, reducing visibility and exacerbating respiratory issues.
