  • mobile monitoring by vehicle mounted instruments - fine scale air pollution data
  • Ozone and Pm2.5 vary over the regional, not neighbourhood scale (ref 17)
  • BC, UFP, NO have highly localized dynamics (refs)
  • linked exposure to census block estimates based on lit
  • concentration gradients and hyperlocal (~ 100 m) variation - NO has the most of this, BC, NO2, UFP have shallower hyperlocal gradients
  • higher concentration ranges in Black/Hispanic neighbourhoods
    • many neighbourhoods w highest avg pollution were subjected to racial discriminatory housing policies
  • no universal trends at local level
