Which health effect is associated with lead exposure in workers?

• A. Elevated blood pressure
• B. Increased speed of reaction time
• C. Improved hearing
• D. Lower blood pressure

Answer: (A)

Lead exposure in workers is linked to cardiovascular effects, especially elevated blood pressure. Chronic exposure can contribute to hypertension through pathways like kidney effects, increased vascular resistance, and oxidative stress that disrupts normal blood vessel function and calcium signaling. This makes higher blood pressure a common and well-supported outcome of lead toxicity. The other options don’t fit because lead’s neurotoxic effects tend to slow processing and reaction times rather than speed them up, it can cause hearing problems rather than improvements, and it does not lower blood pressure—in fact, it’s more likely to raise it.
