| Summary: | 碩士 === 中華醫事科技大學 === 生物安全衛生研究所 === 101 === As an island that depends on the ocean, we have been disregarding the marine environment for a long period of time. Our ocean has been seriously damaged and polluted. Hence, we must have more studies and understandings focused on marine environment. Environmental Protection Bureau of Tainan City Government has specially proposed this project: Project of Marine Environmental Monitor and Pollution Emergency Response for Tainan City 2011 to have direct understandings in present situations of sea areas in Tainan City, and to protect these areas from being polluted and damaged.
This research investigates three times water qualities, and ranges from Bajhang River of northern Tainan to Erren River of southern Tainan. The results match Tainan City standards, such as Chl-a 0.27~5.73 μg/L, Suspended solids 4.0~66.2 mg/L, Dissolved Oxygen 6.2~8.3 mg/L, pH 8.0~8.2, and Ammonia Nitrogen 0.04~1.06 mg/L.
As for the major feeding territory and activity areas of Black-faced Spoonbill, we investigate nine times water qualities and compares to the Class-A sea area water quality standard of Environmental Protection Administration. The results show higher dissolved oxygen than the previous year and much lower concentration of suspended solids and Ammonia nitrogen than the previous year. Above three results show the water quality has been improved. However, the Biochemical oxygen demand is over the standard of the Class-A sea area water quality. There are many aquacultures along the coasts and constantly discharge organic waste water; hence, the result may be slightly higher.
