Copper for treatment of Wilson's disease have been investigated for use in cancer therapy. Copper is an essential trace element in plants and animals, but not all microorganisms. The human body contains copper at a level of about 1.4 to 2.1 mg per kg of body mass. Copper is absorbed in the gut, then transported to the liver bound to albumin. After processing in the liver, copper is distributed to other tissues in a second phase, which involves the protein ceruloplasmin, carrying the majority of copper in blood. Ceruloplasmin also carries the copper that is excreted in milk, and is particularly
Blood lead level glass of water containing lead and absorb 50% of it. An adult might only retain 10% of the lead in that water. And once the lead is in the child's body, it reaches the brain through the not fully developed blood brain barrier. The body removes lead from blood and stores it in bone, but in children it subsequently leaves the bone more readily compared to adults. "Lead that has accumulated in a woman's bones is removed from her bones and passes freely from mother to child; maternal and fetal blood lead levels are virtually identical. Once in the fetal
