Write short note on lead poisoning

Lead is a highly toxic metal and a very strong poison. Lead poisoning is a serious and sometimes fatal condition. It occurs when lead builds up in the body.

Lead is found in lead-based paints, including paint on the walls of old houses and toys. It is also found in:

• art supplies
• contaminated dust
• gasoline products sold outside of the United States and Canada

Lead poisoning usually occurs over a period of months or years. It can cause severe mental and physical impairment. Young children are most vulnerable.

Children get lead in their bodies by putting the lead-containing objects in their mouths. Touching the lead and then putting their fingers in their mouths may also poison them. Lead is more harmful to children because their brains and nervous systems are still developing.

Lead poisoning can be treated, but any damage caused cannot be reversed.
