Massport collects ambient (outdoor) nitrogen dioxide concentration data using diffusion tubes at locations throughout the airport and in neighboring communities. The program began in 1982 and is intended to track ambient nitrogen dioxide levels at Boston Logan and compare them to the levels in nearby communities and to the National Ambient Air Quality Standards (NAAQS).

Centerfield Taxiway Air Quality Monitoring Study
In 2008 Massport began a $1.6 million air quality monitoring study in and around Logan Airport in compliance with its Massachusetts Environmental Policy Act (MEPA) Section 61 findings for the centerfield taxiway component of the Logan Airside Improvements Project.
The intent of the study is to assess air quality changes related to the operation of the new centerfield taxiway by measuring air quality data in communities around Logan Airport both before and after the centerfield taxiway became operational, with an emphasis on ambient (i.e., outdoor) levels of particulate matter and hazardous air pollutants.

Nitrogen Dioxide Emissions by Airline
As part of the reporting process, the Air Quality Initiative calls for an itemization of nitrogen dioxide emissions generated by activities at Logan Airport according to the individual airline operator.
