Content: CCA accounts for about 90 percent of all the arsenic used in the United States. It is added to wood used to build houses and other wooden structures. It prevents organisms from growing in the wood and causing it to rot. In 1996, about 19,200,000 metric tons of arsenic were used for this purpose. There is significant concern about the use of arsenic-treated wood in playground equipment and raised garden beds because of toxicity. Health effects
Arsenic and its compounds are toxic to animals. In low doses, arsenic produces nausea, vomiting, and diarrhea. In larger doses, it causes abnormal heart beat, damage to blood vessels, and a feeling of "pins and needles" in hands and feet. Small corns or warts may begin to develop on the palms of the hands and the soles of the feet. Direct contact with the skin can cause redness and swelling.
