CONSEQUENTIAL SPECIES OF HEAVY METALS IN HIGHWAY RUNOFF
Speciation of heavy metals in aquatic systems plays a key role in their transport, chemical reactions, and bioavailability. Those physical and chemical forms that may cause significant consequences, known as consequential species, should be identified before the potential environmental impact of the metal can be determined. Species of dissolved lead, zinc, copper, and cadmium were identified by using anodic stripping voltametry for rainfall, highway and bridge runoff, and receiving streams at the intersections of Maitland Interchange and I-4, and US-17-92 and Shingle Creek in the central Florida area. Natural water systems reduce ionic species by complexation of incoming trace metals, which results in the reduction of their toxic effects. Most of the heavy metals in highway runoff that are discharged into detention/retention ponds similar to the Maitland site are concentrated in the upper layer (approximately 5 to 6.8 cm) of the bottom sediments. The potential for their release is unlikely if an aerobic environment of the sediment is maintained.
