碩士 === 逢甲大學 === 土木工程學系 === 101 === Based on the research, the dust has been produced during engineering constructing which belongs to fugitive emissions. However, constructional engineering labors have exposed in a high percent environment of dust, noise and other pernicious factors whose respiratory systems, eyes, skins and listen comprehension might be harmed. The industry and commerce have been rapid growing lately and also the information and knowledge have well developed which influence human being start pursuing better living quality and concern about indoor air quality and indoor environment as well. Yet, the engineering construction environments have rarely concerned by the mass population, but there are still thousands of house repairing cases being processed. As the main constructions are proceeding indoor, but there are quite limited researches being in public, so it has been concerned a worth project to be analyzed. This research targets on the dust diameter of suspended particulates is smaller then and or equal to 2.5 um and smaller then and or equal to 10 um, not catalogue the standard of suspended particulate diameter. The research methods will be used via literature review, questionnaires survey, simulation experiment, contrastive experiment and also sample experiment figures to collect PM2.5 and PM10 in a construction site and at the same time will use interview or questionnaire to test and verify. The data received from the experiments will cross check with the interview data to find out the related factors and bring up a method or a strategy. The data of the experiment, which was measured on a construction site, found that when mixing cement and sand, and cutting ceramic tiles would produce more flying dust than the standard of indoor air quality recommended by Environmental Protection Administration Executive Yuan, R.O.C(Taiwan). Spraying is the most effective and best way to reduce the amount of dust in the air, thus serving as a solution in the experiment. It&;#39;s obvious that the data acquired from the questionnaires and interviews is relative to the workers&;#39; working environments and hygienic habits. The research only focused on some parts of the new constructions in winter; therefore, it didn&;#39;t include measurements during spring, summer and fall. The theme of the study in the future could consider revising this section due to the expansion of reconstruction markets and the saturation of new constructions. Measurements done separately in different seasons could be the future objective. Better effects might be achieved by using a mask on the mannequin to acquire a measurement in the future than by watering and spraying as the only proposed solutions.
