When present in the air in a quantity greater than.8 milligrammes per litre, it produces serious symptoms and even death from oedema of the lungs. In a proportion not exceeding.1 milligrammes per litre, ozone becomes a powerful therapeutic agent. The question of dose is therefore of the greatest importance. Unfortunately the estimation of ozone is a procedure which can only be carried out in the laboratory. It depends on the property which ozone possesses of decomposing potassium iodide. The liberated iodine may be estimated by means of hyposulphite of soda in the presence of starch. Another method is to use arsenic acid, which is reduced to arsenious acid by the liberated iodine. The determination of the quantity of arsenious acid before and after the passage of ozone through the solution will give the quantity of iodine liberated. It is most important to determine whether the ozone is accompanied by nitrous products. Bordier's method is to shake up the ozonised air with a solution of meta-phenylene diamine, which takes a brown colour with nitrous products. The air may also be shaken up with a solution of potash, subsequently examining the solution for nitrates and nitrites. We shall proceed to the study of the action of ozone on the blood, on microbes, and on the higher animals. 352. Action of Ozone on the Blood.--In the pulmonary alveoli, the haemoglobin of the blood takes up oxygen from the air and is transformed into oxy-haemoglobin. This oxyhaemoglobin carries the oxygen to the tissues and is there reduced again to haemoglobin. According to Labbe's observations, ozone augments the proportion of...show more
