CDC guidance states that health risk in a child begins at which blood lead level, with death risk at 80 ug/dL or higher?

CDC guidance states that health risk in a child begins at which blood lead level, with death risk at 80 ug/dL or higher?

• A. False
• B. True
• C. Not sure
• D. Unknown

Answer: (B)

Lead exposure is harmful to children even at very low levels, and there is no safe threshold. The health effects we see—such as impacts on IQ, attention, and behavior—can begin well below the high concentrations that cause acute illness. As blood lead levels rise, the risk increases in a dose‑response manner, and at very high levels the chance of life-threatening outcomes, including death, becomes possible. CDC guidance uses a reference value to identify those with elevated exposure, but the key idea is that health risk starts at detectable levels of lead and grows with higher levels, with death risk around 80 µg/dL or higher. This alignment makes the statement true.
