Air Pollution Monitoring
In order to understand how best to improve our air quality, the City has been engaged in monitoring air quality throughout all five boroughs at certain times. This effort helps the City improve its air quality policies and enforcement. DEP can also monitor the air quality for specific pollutants like asbestos during emergencies such as 9/11 or an event with wide-area impact.

New York City Community Air Survey
The New York City Department of Health and Mental Hygiene (DOHMH) partners with Queens College to conduct the New York City Community Air Survey (NYCCAS) which measures air pollution at roughly 150 locations in the New York City. This program studies how pollutants from traffic, buildings boilers and furnaces, and other sources impact air quality in different neighborhoods. NYCCAS monitors pollutants that cause health problems such as fine particles, nitrogen oxides, elemental carbon (a marker for diesel exhaust particles), sulfur dioxide and ozone.
Tree Debris Burning Disposal at Floyd Bennett Field
