Other metals are accordingly to the EPA to be monitored with care as they also<br />

create health risks. Some <strong>of</strong> them are even needed as trace elements for good<br />

body functioning but are toxic in elevated concentrations. Zinc and copper for<br />

example are essential for certain physiological processes and symptoms are<br />

related to a lack <strong>of</strong> them. To high levels on the other side will also cause<br />

problems so it is again a question <strong>of</strong> homeostasis.<br />
