Which organ is primarily affected by mercury?

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

Answer: (C)

Mercury has a significant impact on the kidneys, making this organ the primary target when exposed to high levels of mercury. The kidneys are responsible for filtering waste and toxins from the blood, and mercury can accumulate in these organs, leading to renal damage and dysfunction. This detrimental effect is particularly pronounced in cases of chronic exposure, where the buildup of mercury can cause nephrotoxicity, resulting in conditions such as proteinuria (excess protein in urine) and ultimately leading to kidney failure if exposure continues.

While other organs such as the heart, liver, and nervous system can also be affected by mercury exposure, the kidneys are the most directly and severely impacted, especially in the context of mercury contamination and its ingestion or inhalation. Understanding this relationship is crucial for recognizing the health risks associated with mercury and implementing appropriate safety measures when handling or encountering this hazardous material.
