Several metals (see also chapter 7 and chapter 11) are essential for biological systems and must be present in a certam concentration range. Too low concentrations lead to a decrease in metabolic activity. At too high concentrations these metals lead to toxicity. Nonessential metals are tolerated at very low concentrattons and inhibit metabolic activny at higher concentrations.
