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.

Copper toxicity gastrointestinal distress. Individuals with glucose-6-phosphate deficiency may be at increased risk of hematologic effects of copper. Hemolytic anemia resulting from the treatment of burns with copper compounds is infrequent. Chronic (long-term) copper exposure can damage the liver and kidneys. Mammals have efficient mechanisms to regulate copper stores such that they are generally protected from excess dietary copper levels. Those same protection mechanisms can cause milder symptoms, which are often misdiagnosed as psychiatric disorders. There is a lot of research on the function of the Cu/Zn ratio in neurological, endocrinological, and psychological conditions. Many of the substances that protect us from
