• Protective biochemical responses:<br />
– Monoxygenase (OCs <strong>and</strong> PAHs)<br />
– Induction <strong>and</strong> binding to metalothionein (Cu,<br />
Cd, Zn <strong>and</strong> Hg)<br />
– Binding to blood plasma, bones <strong>and</strong> hair<br />
(Metals <strong>and</strong> xenobiotics)<br />
– Dissolving in fat (organics- e.g. OCs)<br />
– Mineralization ( e.g. MeHg to Hg 2+)<br />
– Demineralization (As to MeAs)
