Question

Blue-baby syndrome results from

• A. Excess of dissolved oxygen
• B. Excess of chlorides
• C. Excess of TDS
• D. Methaemoglobin

Answer 1

The correct option is D Methaemoglobin

Blue baby syndrome

Higher nitrate levels cause a blood disorder in infants of 6 months. This disorder is called blue baby syndrome. The nitrates get converted to nitrites in the body which then bind to the haemoglobin.

The methemoglobin thus formed will be unable to carry oxygen resulting in the skin of the baby turning blue. This is called blue baby syndrome.

Final answer

(D) Methaemoglobin
