Due to screening, loading, transport and piling of sand and gravel(hereinafter referred to as sand and gravel processing), A lot of activities related to sand and gravel processing. The sand and gravel, when agitated, create particulate matter that has long affected the air quality in those areas. In the river basins within Nantou County, the sloped river banks collapse, lands slide and huge amount of debris move downstream to deposit on the riverbed as a result of 921 Earthquake and the super-heavy rain down washed in typhoon seasons in every summer and autumn, and necessitate regular dredging, which makes the sand and gravel processing activities more frequent and more concentrated. In order to control and prevent the polluting behaviors arised from the disposing roads in dredging engineering, the processing at depots and the transportation of dump trucks, the Environmental Protection Bureau of Nantou county launched and carried out various pollution control strategies and practice. This research explored possible controlling and preventing measures including the legal and technical aspects administered by the Environmental Protection Bureau of Nantou County since 2003, and the intensity survey in dredging engineering and activities at depots, and other data like TSP taken on-site, the effect of intensity of activities at depots on the generation of air pollution and whether these pollution control measures taken has been effective in improving air quality. Looking at all the sand and gravel depot controls the Bureau has enforced special programs, and the study on various baseline data to effectively comprehend and to control the polluting emission at the depot. It is found that due to the enforcement of pollution controlling measures and the decrease in pollutant status were observed. There is a trend of lessening in the changes of depot yield during the period of 2004 to 2007, of particulate matter emission at depot and of annual mean airborne particulate obtained at Chusan Air Quality Monitoring Station. By linear regression analyses, close relation were found between changes in depot yield and annual mean particulate concentrations observed at Chusan. 望熙榮 2009 學位論文 ; thesis 91 zh-TW |
