"淡水河流域因受到家庭污水排入影響，造成其上中游缺氧，其中下游因海水入侵水中溶氧逐漸飽和，本計晝擬研究橈足類浮游動物在水體環境中從缺氧環境到有氧環境其生態變化之機制，及在這樣的環境中橈足類浮游動物對微量元素蓄積能力行為的影響。本計晝擬於淡水河上中下游海域設定共15個測站，租用漁船採取表層水(ca. 2m)，及浮游動物拖網作業，收集浮游動物，分析水樣中之基本水質（鹽度、酸驗度、溶氧、磷酸鹽、矽酸鹽、氨氮、亞硝酸鹽和硝酸鹽）項目，另分析橈足類浮游動物及水樣中溶解態微量元素(Ag、Al、As、Ba、Bi、Cd、Co、Cr、Cs、Cu、Fe、Mn、Ni、 Rb、Pb、Sr、Zn、Se、Hg)濃度，瞭解在缺氧及有氧之自然海域環境中，橈足類浮游動物生態變化與其對微量金屬元素累積能力之影嚮。""The upper and middle sections of the Danshuei estuary are anoxic environments because of untreated and treated domestic effluents and industrial wastes discharged into the estuary from its tributaries. The lower estuary gradually becomes oxic environment due to the intrusion of seawater. Thus, the Danshuei Estuary provides a natural environment to study the ecological variation of the marine copepod under such an anoxic/oxic estuarine environment. This project will collect the estuarine water and copepod samples from the Danshuei Estuary in Northern Taiwan to study the ecological change of the marine copepod and to 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 estuarine water 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 anoxic/oxic estuarine environment."
