"龜山島海域有海底熱泉湧出，促使周遭海域微量金屬元素濃度增加，浮游動物中的橈足類在許多海域調查中其數量經常佔浮游動物的最主要部份，文獻顯示海水中浮游動物之橈足類動物對微量金屬元素之生物濃縮倍數可答達 103-107，本計畫擬在龜山島附近海域設定六個測站，採取海水中浮游動物樣品與海水，並挑選主要優勢種之橈足類浮游動物樣品分析其微量金屬元素(Ag、Al、As、Ba、Bi、Cd、Co、Cr、Cs、Cu、Fe、Mn、 Ni、Rb、Pb、Sr、Zn、Se、Hg)濃度。瞭解在有海底熱泉之自然海域環境中，不同物種之橈足類浮游動物對微量金屬元素之累積能力與喜好，並探討龜山島海底熱泉之影響範圍與對橈足類浮游動物生態影嚮。""It is known that there has a hydrothermal vent around the Kueishantao islet, which elevating the concentrations of trace elements in seawater near the Kueishantao islet. The abundance of copepod is generally the richest among the zooplankton species in seawater. Many studies have indicated that marine copepods have a great ability to accumulate trace metals in seawater and the ranges of bioconcentration factor can are 103-107, varying with different elements. This project will collect seawater and copepod samples in seawater around the Kueishantao islet and study the accumulation ability of trace elements (Ag、Al、As、Ba、 Bi、Cd、Co、Cr、Cs、Cu、Fe、Mn、Ni、Rb、Pb、Sr、Zn、Se、Hg) by means of determining trace elements concentrations in dissolved phases of seawater and in dominant species of copepods. The determination of trace elements in the collected copepod samples will be analyzed by ICP-MS prior to digestion by HNO3-HCl acid in the water bath. The concentrations of trace elements in seawater samples are also analyzed by ICP-MS after pre-concentration. The analyzed results can help us to understand the bioaccumulation ability of trace elements by marine copepods and to evaluate the ecological system of copepods under the influence of the hydrothermal vent input."
