IS 45 Air Monitoring Station, New York City | New York Environmental Monitoring

IS 45 is an operational air monitoring station located at School IS 45 on 1st Avenue in New York City, New York. Operated by the New York State Department of Environmental Conservation, this station is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other atmospheric parameters across the United States. The station collects ambient air samples to assess local air quality, supporting regulatory compliance with the Clean Air Act and National Ambient Air Quality Standards (NAAQS). While specific parameters measured are not detailed, typical urban monitoring stations in New York City track pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. The station's location at a school provides representative data for community exposure. As part of New York State's extensive monitoring network, IS 45 contributes to public health protection by informing air quality forecasts and regulatory decisions. The data supports the state's efforts to reduce emissions and improve air quality in one of the most densely populated urban areas in the United States, benefiting millions of residents.

New York City faces air quality challenges from vehicle emissions, building heating, and industrial sources. The IS 45 station, situated in a mixed residential-commercial area, helps characterize local pollution patterns. Its placement at a school allows for monitoring of children's exposure, a key concern for environmental health. The station's data supports the state's compliance with NAAQS and contributes to regional air quality management strategies.
