Because of their
versatility in a wide variety of chemical reactions, many trace
metals are essentiAAal micronutrients in biological systems. However,
their reactivity can also lead to toxicity even at relatively low
levels. This delicate limit between trace metals as micronutrients
and toxicants plays a crucial role in the balance of life. Knowledge
of the metal distribution among the different physical and chemical
forms (i.e. chemical speciation) is therefore essential for
predicting their environmental impacts.
