  • Abstract en In this study, the emission sources of various types of airborne organic matter, which deteriorates cement concrete by penetrating into it together with moisture, were identified using high-performance liquid chromatography and gas chromatograph mass spectrometer. As a result, it was revealed that the types of organic matter contained in decalcified cement concrete were almost the same as those found in total suspended matter in the air, and that they were primarily being emitted as particles of exhaust from diesel vehicles and radial tires used in summer. Such organic matter includes substances suspected as having endocrine disrupting properties. Hydrolysis occurs when these substances penetrate into a highly alkaline cement concrete, and leads to deterioration of cement concrete and the release of particular kinds of alcohols and ammonia gases, which pollute indoor air and can cause sick building syndrome.
