Health Implications

Massachusetts currently meets the nitrogen dioxide (NO2) ambient air quality standards and does not experience unhealthy levels of NO2.

Because NO2 is a criteria pollutant, MassDEP continues to monitor for NO2 to ensure that NO2 levels continue to meet the standard.

goodNo AQI
The monitors for NO2 are grey because, while data is being reported, no AQI can be calculated. Click the circle for a monitor to see the value or select Table View. NO2 has no short-term Federal standard, and EPA specifies no AQI value below concentrations of 0.65 ppm NO2, which is much higher than levels experienced in Massachusetts currently.
