Which of the following is a known effect of benzene exposure?

• A. Muscle cramps
• B. Cancer
• C. Skin irritation
• D. Insomnia

Answer: (B)

Benzene exposure is primarily associated with an increased risk of developing cancer, particularly hematologic cancers such as leukemia. This is due to benzene's ability to affect the bone marrow, leading to disruptions in blood cell production. Chronic exposure to benzene is well-documented in scientific literature as a risk factor for various forms of cancer.

The other options, while they may relate to different substances or exposures, do not specifically tie back to benzene in the way that cancer does. Muscle cramps, skin irritation, and insomnia are not well-established effects of benzene exposure, making them less relevant in this context. Understanding the carcinogenic properties of benzene is crucial for those working in environments where they may encounter this hazardous material, underscoring the importance of appropriate safety measures and monitoring to minimize exposure.
