Abstract
Synthetic chelating agents and the metals they carry can be environmental pol1utants. Chelating agents are organic molecules with two or more functional groups which bond
metals by encircling them with ligand "arms". Metals, which would normally be stationary in soils and sediments, can be resolubilized and transported by chelating materials. Chelates are often used to scavenge metals in industrial processes and can carry metals into the environment.
Preliminary research is needed to determine
the kinetics of chelating agents being sorbed or degraded in order to further study the impact they, and the metals they carry, have on soils, sediments and waters. Chelating agents could have profound influences on the free toxic metal concentrations in waters in Georgia due to possible release from soils and sediments.
