中文摘要 | 本計畫之調查工作自81年10月至82年6月止,調查屏東縣大鵬灣之水質及蚵體之重 金屬含量,檢測項目為銅、鋅、鉛、鎘、鎳、及汞等。檢測結果顯示大鵬灣水質中銅含量介 於 0.9 ∼ 16.2 ppb 之間,低於臺灣區海域水質標準規定值 20 ppb;鋅含量介於 N.D. ∼ 20.2 ppb 之間,亦不超過標準規定值 40 ppb,其餘鉛、鎘、鎳、汞等含量均低於標準規定 值,顯示大鵬灣水域目前尚未受到嚴重污染。 大鵬灣水域養殖之牡蠣,銅含量介於 1.7 ∼ 36.1 ppm,鋅介於 24.6 ∼ 149 ppm,大鵬灣 水域養殖之其它水產品包括蝦體、魚體等之重金屬含量分析顯示亦皆在安全限量範圍內。 東港、林邊、枋寮等地區之魚蝦養殖水中重金屬含量皆在安全限量內,但枋寮養殖池水之銅 含量介於 N.D. ∼ 154.4 ppb, 其變異範圍甚大。 東港地區養殖池底泥中之銅含量介於 12.3 ∼ 146 ppm,較臺南縣養殖池底泥中銅含量( 0.9 ∼ 6.0 ppm )高出甚多, 且變異 範圍相當大,仍需持續注意追蹤監視之。 |
英文摘要 | This study was conducted to monitor the pollution of fish and aqueous culture area by heavy metals in Ping-Tung. Samples of water and fishes collected from Da-Pung Wan、 Dong-Gang、 Lin-Bian、 Fong-Liaw and Tainan area during the period of Oct. 1992 to June 1993, were analyzed for the content of heavy metals including Cu、Zn、 Pb、 Cd、Ni and Hg. The content of Cu and Zn of water samples from Da-Pung Wan were in the range of 0.9-16.2 and N.D.-20.2 ppb respectively, which were under the recommended or tolerated values of trace elements in marine water defined by the government of Taiwan. The contents of the other four elements were also far below the recommended values, indicating the Da-Pung Wan area was not seriously polluted yet by heavy metals. Copper and Zinc were the major elements accumulated in oyster. The content of Cu and Zn in oyster varied with the culture area, which cultured in Da-Pung Wan area were in the range of 1.7-36.1 and 24.6-149 ppm respectively, which were less than those in oyster cultured in Chia-Yi and Pu-Dai area where seriously polluted by Cu had been reported. The content of heavy rnetals in water samples collected from the culture ponds of Dong-Gang、 Lin-Bian and Fong-Liaw area were also below the defined value of trace elements in water except the content of Cu in culture water from Dong-Gang area ranged from N.D.-154.4 ppb. The high level of Cu in water may be due to the improper application of algaecide, of which Cu was the major ingredient. The content of heavy metal in the sediments of culture pond was also investigated in this study. Results indicated that the content of Cu in the sediment from Dong-Gang area were varied in the range of 12.3-146 ppm, which was much higher than those found in Tainan area (0.9-6.0 ppm). |
