Absorbed from the intestines into the blood, nitrites (NO2-) interact with the hemoglobin of the blood and block its respiratory function, turning part of the hemoglobin (HbFe2+) into methemoglobin (HbFe3+), unable to transfer oxygen from the lungs to tissues. With the formation of a large amount of methemoglobin, oxygen starvation of tissues occurs, which can cause damage to the central nervous system. 10 to 20 % - of methemoglobin (HbFe3+) - asymptomatic cyanosis, 20 to 50% of methemoglobin (HbFe3+) -hypoxia develop, > 50% of methemoglobin (HbFe3+) - the person will die. The body weight of the average person is 60 kg. Blood mass averages 8% of a person’s body weight; blood density ρ = 1,050 g/cm3, the hemoglobin (Hb) content in it is 14 g per 100 ml. molecular weight of hemoglobin 65-68 kg/mol (use 68 kg/mol for calculation). Assume that 1 mole of hemoglobin reacts with one mole of nitrite ion to form 1 NO molecule: HbFe2+ + NO2- → HbFe3+ + NO will a 290 mg dose of sodium nitrite…
