Vedclass · Answer

(B) The disease methemoglobinemia,also known as 'blue baby syndrome',is caused by the presence of excess nitrates $(NO_3^{-})$ in drinking water.When ingested,nitrates are reduced to nitrites $(NO_2^{-})$ in the body,which then react with hemoglobin to form methemoglobin.Methemoglobin is unable to transport oxygen effectively,leading to oxygen deficiency in the blood.

Which of the following,when present in excess in drinking water,causes the disease methemoglobinemia?
