All of the data were divided into three stages, and then analyzed according to the features of control status, environmental medium, land usage, area distribution, and pollutant categories to investigate their characteristics and trends. The results showed as following: First of all, on the part of control status, the local authorities pronounced control sites had the largest amount of pollution sites for whole period and every stage ,the following were the pronounced remediation sites with more serious pollution after preliminarily assessment by EPA, the latest were the groundwater usage restriction regions with uncertain sources of pollution; Secondly, in terms of environmental media, soil pollution sites occupied the great majority for whole period and every stage , following were the groundwater pollution sites, while soil and groundwater pollution sites were the least, the main reason was that most of the pollutants came from the adsorption of ground and soil; for land usage, the amount sequence was agricultural land, factories, gas stations, other categories, illegal disposal sites, and storage tanks, which caused due to the scope pollution investigation process over various types of industrial and land number-based pronounced; other terms of area distribution, the number of pollution sites had expanded from 15 to 18 to 20 counties/cities during the first stage to the third stage , and concentrated in those more prospering counties/cities of agriculture, industry and commerce, the main reason was they got more pollution sources, in addition; in terms of the pollutant categories, the soil pollutants were mainly copper, zinc, chromium, nickel, while VOCs was the most part of groundwater pollutant, the reason of the former was due to Taiwan’s prospering metal industry, the latter was because of the factories and gas stations nation-wide. 李芳胤 2013 學位論文 ; thesis 55 zh-TW |
