Long-term exposure to cadmium is particularly harmful to the kidneys, making kidney toxicity a well-documented health effect associated with this heavy metal. Cadmium accumulates in the body over time, predominantly in the kidneys, leading to damage that can impair renal function. This toxicity results in specific symptoms and complications such as proteinuria (the presence of excess protein in the urine), which indicates kidney damage, and can progress to more severe conditions like kidney failure if exposure continues.

The pathways of cadmium toxicity in the kidneys involve oxidative stress and disruption of cellular functions, which ultimately impact overall kidney health and function. Given the known mechanisms of cadmium's effect on renal tissues and the epidemiological evidence linking cadmium exposure to kidney damage, this option aligns closely with recognized health risks in occupational and environmental settings involving cadmium exposure.
