Paralysis of respiratory cilia and can damage epithelial tissue, so easily penetrated pathogenic microorganisms, weaken the body's resistance to disease. Usually in the form of ammonia gas is inhaled, after ammonia is easily inhaled into the lungs through the alveoli into the blood, combined with hemoglobin, oxygen transport function destruction. Ammonia into the alveoli, the small part of the carbon dioxide and the rest is absorbed into the blood, a small amount of ammonia can be with the sweat, urine or breath excreted. In order to prove that a low concentration of ammonia in the air hazards and effects on human health, experts monitoring the workers working in contact with 3-13 mg / m concentration of ammonia in the indoor environment, which lasted 8 hours, 10 people in each group, Compared with no contact with ammonia healthy people, find contact 13 mg / cubic meter man, urinary urea and ammonia levels were increased, blood urea increased significantly.
