Question

Lead concentration in blood is considered alarming if it is

• A. 20 $\mu$/100 ml
• B. 30 $\mu$/100 ml
• C. 4-6 $\mu$/100 ml
• D. 10 $\mu$/100 ml

Answer 1

The correct option is C 4-6 $\mu$/100 ml

The Centers for Disease Control and Prevention (CDC) states that a blood lead level of average 5 g/dL or above is a cause for concern in children. However, lead can impair development even at blood lead below 5 g/dL. Adults that are exposed to a dangerous amount of lead can experience anaemia, nervous system dysfunction, weakness, hypertension, kidney problems, decreased fertility and increased level of miscarriages, and low birth weight and premature deliveries.
