Question

If lead accumulation occurs for long in body, outcomes may include _____.

• A. Death
• B. Coma
• C. Lead poisoning
• D. All of the above

Answer 1

Answer: (D)

All of the above

Lead is a cumulative toxicant that affects multiple body systems. Lead in the body is distributed to the brain, liver, kidney and bones. It is stored in the teeth and bones, where it accumulates over time. There is no known level of lead exposure that is considered safe. Lead can have serious consequences for the health of children. If lead accumulation occurs for long in body, it attacks the brain and central nervous system to cause coma, convulsions and even death. Children who survive severe lead poisoning may be left with mental retardation and behavioural disorders.
