New York City’s air quality dropped to unhealthy levels Wednesday morning, but don’t blame the Canadian wildfires — this time fireworks and sizzling weather are the main culprits.
Conditions improved enough by 11 a.m. local time to reach moderate levels across most of the city, with pockets of Brooklyn and Staten Island rated unhealthy for sensitive groups, according to the Environmental Protection Agency’s AirNow map. Air quality was also moderate for most of the Great Lakes region and mid-Atlantic.
