Q: Blue Baby Disease in children is due presence of _____in water.
  • A. excess nitrates
  • B. excess sulphates
  • C. excess chloride
  • D. excess carbonates
Correct Answer: Option A - • Blue baby disease in children is due to presence of excess amount of nitrates in water. • The permissible value of nitrate in water should be 45 mg/l. • Nitrates have been defined as the non-objectionable final end product in aerobic treatment of sewage, yet its concentration in potable water are controlled, because larger concentrations (above 45 ppm) may cause nitrate poisoning in infants. • This happens because there exists lower acidity in the intestines of the infants, which permits growth of nitrate reducing bacteria, which convent nitrates to nitrites, the nitrites, when absorbed in blood, prove very harmful, because they have greater affinity for hemoglobin than does oxygen and thus, nitrite replace oxygen in the blood complex. This diseases, popularly called blue baby disease or technically as methaemoglobinemia.
