The environmental movement, effects, and fates of hazardous waste compounds
are strongly related to their chemical properties. For example, a toxic heavy metal
cationic species, such as Pb2+ ion, may be strongly held by negatively charged soil
solids. If the lead is chelated by the chelating EDTA anion, represented Y4-, it
becomes much more mobile as PbY2-, an anionic form.
