What type of chemical is benzene known to affect?

• A. Blood
• B. Liver
• C. Nervous system
• D. Kidney

Answer: (A)

Benzene is primarily known to affect blood, specifically by impacting the production of blood cells. Prolonged exposure to benzene can result in various hematologic conditions due to its bone marrow suppressive effects. It is associated with a decreased production of red blood cells, leading to anemia, as well as a decrease in white blood cells, which can increase the risk of infections. This is particularly significant as benzene is a known carcinogen, with long-term exposure linked to disorders such as leukemias, which directly relate to the health of the blood and its components. Understanding benzene's effects on blood is critical for assessing health risks in environments where exposure is possible.
