Does lead stay in body forever?

Lead stays in the body for different periods of time, depending on where it is. Half of the lead in the blood will be excreted in 25 days (this is called the “half-life”).

How is lead obtained?

Most lead is obtained by roasting galena in hot air, although nearly one third of the lead used in the United States is obtained through recycling efforts. Lead is a soft, malleable and corrosion resistant material. The ancient Romans used lead to make water pipes, some of which are still in use today.

What rock is lead found in?

The main lead mineral is galena (PbS), which contains 86.6% lead by mass. Cerussite (PbCO3) and anglesite (PbSO4) commonly occur in the near-surface weathered or oxidised zone of lead orebodies. Lead deposits form from hot, aqueous (or hydrothermal) fluids generated within the earth.

Different materials have different densities. For example, the mass density of gold is 19.3 g/cc, lead is 11.4 g/cc, copper is 9.0 g/cc, aluminum is 2.7 g/cc, water is 1.0 g/cc (1g/cc = 1 gram per cubic centimeter). If we want the density in English units we could use 11.1 oz/cubic inch as the density of gold.
