中文摘要 | 本研究係利用微分脈波陽極脫除伏安法(differential pulse anodic stripping voltammetry, DPASV)測定不安定銅(labile copper)。在熊蝦(Penaeus semisulcatus)苗培育於水溫27±1℃、30±1℃、33±1℃及36±1℃下,研究第六天至第十天的培育水對銅之錯合能力。結果顯示,於33℃的處理組,在糠蝦期後,其培育水對銅有較高的錯合能力(1.3~15.9 μg/l);而30℃的處理組,其蝦苗培育至後期幼蟲第一期的育成率最高(84 %),且在糠蝦期前,其培育水對銅的錯合能力最高(27.5 μg/l),在糠蝦期後,則維持在2.8~11.9 μg/l。27℃的處理組,其蝦苗育成率次高(77%),在糠蝦期後,其培育水對銅的錯合能力為2.8~14.9 μg/l。 36℃的處理組,蝦苗的育成率最差,平均僅 7%,而其培育水對銅之錯合能力亦不穩定。培育水的錯合物種型態以強穩定錯合型和弱穩定錯合型為主,本實驗證明蝦苗培育水中有機物質可螯合銅離子,減低銅離子對於蝦苗的毒性。 |
英文摘要 | A measurement of labile copper was conducted by differential pulse anodic stripping voltammetry (DPASV). The bear prawn, Penaeus semisulcatus, larvae were raised at different water temperature (27±1℃, 30±1℃, 33±1℃ and 36±1℃). The copper complexing capacity in the tank water was measured from the sixth to the tenth day, after larvae were stocked. The result showed that the water in the 33℃ treatment almost had the highest copper complexing capacity (1.3-15.9 μg/l) after the mysis stage. The survival rate (84%) of prawn larvae was the highest in the 30℃ treatment. Before the mysis stage, the copper complexing capacity (27.5 μg/l) in the 30℃ treatment was the highest. However, the copper complexing capacity in the 30 ℃ treatment water after Mysis stage ranged between 2.8 and 11.9 μg/l. In the 27℃ treatment, the survival rate of the larvae was 77% and the copper complexing capacity of culture water after the mysis stage ranged between 2.8 and 14.9 μg/l. The survival rate of prawn larvae in the 36℃ treatment were the lowest (7%), and the copper complexing capacity of culture water was unstable. Most of the complexes belonged to strong stable nonlabile complexes and weak stable nonlabile complexes. |
