碩士 === 國立雲林科技大學 === 環境與安全衛生工程系碩士班 === 100 === Variational tendency of particulate matter less than 10 micrometer (PM10) using the data from 12 air quality monitoring sites of central Taiwan was investigated and comparison with calculated fugitive dust emission between using Taiwan Emission Data System (TEDS) and using total suspended particulate (TSP) concentration was studied. First, the data of PM10 concentration from 2000 to 2010 indicated better and better air quality at central Taiwan, showing the highest PM10 concentration of 108.07 μg/m3 at central Taiwan and the lowest PM10 concentration of 43.96 μg/m3 at central Taiwan. For evaluation of fugitive dust by vehicles, comparison with calculated emission using TEDS and TSP showed that the result of calculated emission using TEDS was eight-fold high than calculated emission using TSP before washing work of the road due to the silt soil value showing 0.67 g/m2. Moreover, the result of calculated emission using TEDS was three-fold high than calculated emission using TSP after washing work of the road due to the silt soil value showing 0.13 g/m2. Therefore, evaluation models of fugitive dust from road should be modified by experimental data. In addition, a new method for evaluation of fugitive dust from road using weight of road dust was developed and it is a suggestion that weight should be less than 0.15 g for A level of road, between 0.15 and 0.6 g for B level, and more than 0.6 g for C level of road.
