Abstract: This
thesis was an analysis of the Environmental Protection Agency's Criteria Air Pollutants
(NAAQS) in the near highway neighborhood of Savin Hill "Over the Bridge" (OTB) in North
Dorchester, Massachusetts. CO, NO2, SO2, O3, PM2.5 and PM10 concentrations were measured
during the morning and evening rush hour commutes of Interstate 93 for 2 weeks in both
the summer of 2007 and the ... read morewinter of 2008. Meteorological and traffic influences were
also assessed. Results demonstrated higher pollutants concentrations than allowed by the
NAAQS during multiple sampling periods. Seasonal differences in concentrations of
pollutants were observed. Variability between sampling sites differed markedly between
pollutants. The prevailing wind direction placed the OTB neighborhood downwind of the
highway pollutant emissions during both summer and winter sampling periods. Travel times
between Braintree and Boston did not display an impact on pollutant
concentrations.
