Health effects of lead: Increased levels of lead affect children the most. In children, low levels of exposure have been linked to damage to the central and peripheral nervous system, learning disabilities, shorter stature, impaired hearing, and impaired formation and function of blood cells. Other at-risk populations include pregnant women who can experience reduced growth of the fetus and premature birth. Adults who consume too much lead can experience cardiovascular issues and decreased kidney function.
Health effects of copper: The Food and Drug Administration recommends a dietary allowance of 2 milligrams (mg) of copper per day. However, eating or drinking too much copper can cause vomiting, diarrhea, stomach cramps, nausea, liver damage, and kidney disease. People with Wilson’s disease and some infants (babies under 1 year) are extra sensitive to copper. Their bodies are not able to get rid of extra copper easily.
