Answer:
Lead is toxic mostly because during biochemical reactions it tries to substitute certain metals. hence while doing this, It disrupts with the proteins that control blood pressure, the production of heme and the formation of sperm. Through reactions that propagate electrical signals in the brain, lead often consumes calcium, which reduces the capacity to think and retrieve information.
