Abstract: | The concentration of total suspended particulate (TSP) matter was determined at commercial, residential, rural and industrial sites in metropolitan Jacksonville during the summers of 1989 and 1990. These data were compared to samples taken at the Mathews Bridge Toll Plaza in 1989 and at a similar location one year later, after removal of the toll facility. All samples were analyzed by reflectance analysis and the approximate elemental carbon content used to estimate the contribution of vehicular traffic at the roadway. The results indicate a significant improvement in air quality at the location of the previous toll facility, but did not show that a widespread improvement resulted from the removal of tolls in Jacksonville, Florida. |
