Lead and Copper Rule especially for young children and pregnant women." It also explained that the rule has reduced copper exposure "that can cause stomach and intestinal distress, liver or kidney damage, and complications of Wilson’s disease in genetically predisposed people." Although lead is a known poison, the mechanical and chemical characteristics of the metal continue to keep lead as an important component in many products. In water supply, lead's durability and workability selected it for use as water pipes. Lead alloys (bronze, brass) are used for plumbing fittings. Lead solders were preferred in plumbing. While lead pipes were replaced by other materials, such
Copper in health childhood cirrhosis) are associated with the improper utilization of copper in the body. All of these diseases involve mutations of genes containing the genetic codes for the production of specific proteins involved in the absorption and distribution of copper. When these proteins are dysfunctional, copper either builds up in the liver or the body fails to absorb copper. These diseases are inherited and cannot be acquired. Adjusting copper levels in the diet or drinking water will not cure these conditions (although therapies are available to manage symptoms of genetic copper excess disease). The study of genetic copper metabolism diseases and
