Question

Which organs are critically affected by environmental exposure to cadmium?

• A. Liver and Lungs
• B. Kidney and Bone
• C. Heart and Brain
• D. Skin and Eyes

Answer 1

Answer:

B. Kidney and Bone

• Kidney and bone are the critical target organs with regard to environmental exposure. The main critical effects include increased excretion of low-molecular weight proteins in the urine (as a result of proximal tubular cell damage) and an increased risk of osteoporosis.

• An increased risk of lung cancer has also been reported following inhalation exposure in occupational settings.

• The margin of safety between the present daily intake of cadmium in the diet and the intake that can result in effects is very narrow and, for highly exposed sub populations, even non-existent.
