97年度臺南縣海域環境監測及海污緊急應變計畫

中文摘要 海洋立國的我們，長期以來對海洋環境的忽略，使我們的海洋遭受嚴重的破壞與污染，所以有必要對海洋環境，作更多的研究與了解。因為，人類生活環境除了陸地，海洋其實是調節人類生活環境最大的寶庫，所以我們要更加愛護海洋環境。因此藉由監測和掌握台南縣海域環境，台南縣環保局特研提出本計畫「97年度臺南縣海域環境監測及海污緊急應變計畫」，提出有效解決台南縣海洋污染防治對策，保護這個生態環境不被破壞及污染，以及在發生船隻漏油事件時，能有效進行海面上油污之清除工作。 本計畫調查範圍為曾文溪以北海域沿海海域水質，北從台南縣海岸北端之八掌溪河口北側，南至網子寮沙洲外南側。本年度3次的水質調查結果與環保署甲類海域水質標準做比較，大部份皆符合甲類海域水質標準。前2次水質合格率皆為100%，第3次水質合格率為98%(其中不合格項目為總磷)。 另本計畫的海域底質監測結果與國外基準值(NOAA)相比較下，發現大部分之重金屬小於TEL(影響門檻值)，其中銅、鎘、鉛、鋅、鉻及汞濃度變化範圍均小於TEL，應該不會對生物造成危害。鎳則有超出TEL，但小於ERL(低影響值,20.9mg/kg)的情形出現，本計畫底質鎳濃度平均值約16.9 mg/kg，相較於其他區域如：台南七股沿岸沉積物(45 mg/kg)、淡水河沉積物(55 mg/kg)、高雄港沉積物(59 mg/kg)、嘉義沿海沉積物(32 mg/kg)，本區域測值均優於其他區域。 而黑面琵鷺重要覓食區與活動區10次的水質調查結果與環保署甲類海域水質標準做比較，結果顯示在溶氧部份，較前一年度濃度高，而懸浮固體物濃度與氨氮濃度，則較前一年度濃度低許多，三者皆有改善情形。而生化需氧量方面，本區域各測點皆超過甲類海域水質標準，與歷年情形相同，由於沿海有很多的養殖漁業，持續地向潟湖排出有機廢水，可能造成測值稍微偏高。另於化學需氧量方面，監測濃度皆較前一年度高，可能亦與沿海養殖漁業排出有機廢水影響與水量變少有關。 此外綜觀永康大灣中排、三爺溪漏油事件、將軍鄉將軍漁港海洋污染漏油事件，由於應變處理得當，並能在第一時間內做好有效的控制與防範，值得作為往後應變類似事件的借鏡。 另外為協助台南縣境內海洋污染防治稽查環保業務，本團隊協助配合港口稽查及船舶稽查兩部份，共計查核426件，大部分為無汙染情形，約佔63%，其次為少許漂浮垃圾及少許浮油花情形，另增加協助辦理其他海洋污染防治宣導，包括辦理宣導活動及印製宣導文宣等，以防止與減少相關海洋污染情形。

2008 Taina County sea area environmental monitoring and sea dirt urgent contingency plan

英文摘要 The seashore marine water quality of the area northern Zheng-yen River basin was investigated, investigation area ranged from the north side of Ba-Zhang River estuary to the south side of Wang-Zi-Liao Sandbank in Tainan County. In comparison with Environmental Protection Agency’s marine water quality standards (Class A), the 3 monitoring results indicate that the water quality is within the standards. The first two monitoring results show that 100% of the water index concentrations are within standards. The third monitoring results show that 98% of the water index concentrations are within standards. In addition, over the years the concentrations of suspended solids and the total phosphorus are in the decline. In comparison with international water quality standards (NOAA), our results show that the majority of heavy mental concentrations are lower than TEL (Threshold Level). The concentration fluctuations of Copper, Cadmium, Lead, Zinc, Chromium and Mercury are lower than TEL. The levels should not cause harm to eco-system. The Nickel level has exceeded TEL standard, but is lower than ERL (Lower threshold, 20.9mg/kg). Nickel concentration detected here shows 16.9 mg/kg, in comparison with the detected Nickel concentrations from other regions, such as Qi-Gu sediment (45 mg/kg), Dan-shui sediment (55 mg/kg), Koahsiung harbor sediment (59 mg/kg), Jia-yi sediment (32 mg/kg), our results indicated better marine water quality. In comparison with Environmental Protection Agency’s marine water quality standards (Class A), our 10 monitoring results of water quality in the natural habitats of Black-faced Spoonbill indicate that the concentrations of DO, N-NH3,SS have improved. The BOD levels of this region mostly surpass marine water quality standards (Class A), it might be due to the overly populated fishery industries. As for COD levels, the detected levels were also higher than last years’, it can also be attributed to the same wastewater discharged by coastal fishery industries. As for the marine petro leakage incidents, following cleanup and the effective and complete handling at the early possible moments were all properly done, All this can be taken as the examples of further similar incidents. For assisting Tainan County marine pollution prevention, our team assisted in the checking of ports and the ships, 426 cases were completed. Only around 37% of the cases turned out to be some pollution events, they are random floating oil and trash problems. In addition, we helped to organize marine pollution prevention info. sessions, which included organizing activities and printing pamphlets.
