A comprehensive study measuring ultrafine particles, lead, and other air pollutants from aviation emissions at Hanscom Field across four surrounding Massachusetts towns. The study found that UFP concentrations were up to two-fold higher at downwind sites and often exceeded WHO guidelines, with the highest impacts in Bedford and Lexington.

This contour plot displays Scanning Mobility Particle Sizer (SMPS) particle bin counts (log10 scale, 2.6–5.0) by particle size (5–382 nm) and local PST time (08:31–12:54) at the SeaTac North monitoring station on September 15, 2025. Brown diamond markers indicate the geometric mean particle diameter over time, generally ranging between approximately 15–30 nm. The chart was generated at 13:08:16 local time on 2025-09-15, with last UTC data at 19:54:26.

This plot shows Scanning Mobility Particle Sizer (SMPS) aerosol particle size distribution data (5–382 nm) collected at the 10th & Weller monitoring site, generated on 2025-09-15 at 13:08:09 PST with last UTC data timestamp of 2025-09-15 19:56:31. The contour plot displays log(10) particle counts over local PST time from approximately 13:11 on September 14 through 12:56 on September 15, with brown diamond markers indicating the geometric mean particle diameter over time.
