摘要：Effects of sulphur dioxide gas, mists of aqueous sulphur dioxide and of sulphuricacid solution and silica gel particles exposed to sulphur dioxide and to sulphuric acid solution on the metal film were studied electronmicroscopically. Mists of aqueous solution of sulphur dioxide and sulphuric acid showed very similar but a little different figures. Sulphur dioxide and particles, absorbing sulphur dioxide or sulphuric acid, showed a corrosive effect on the metals with or after the exposure to high humidity. It was emphasized that the biological effects of these pollutants should be consideredtogether with air humidity.
