A study was supported by SUS/STAR to investigate the fate of heavy metals in bridge runoff which are received by surrounding floodplains. Three bridge sites in Central Florida were selected and various locations in each site were sampled. Soil, plant, and water samples were analyzed for Cd, Zn, Cu, Fe, Pb, Ni and Cr. Statistical analysis of results for heavy metal content of plants and soils at control versus bridge sampling areas were conducted. In agreement with other investigators, Pb was found to be a good indicator of highway pollution in soil, plants and water. Possible mechanisms for metal sorption were developed from laboratory sorption experiments. Soil capacities for lead increased with increasing pH, organic content, and soil buffering capacity. Also, information about the types of heavy metal compounds in a floodplain was obtained using various extraction solutions.
