Bathurst Harbour (1989) Trace Metals

Bathurst Harbour and Macquarie Harbour are estuarine systems on the west coast of Tasmania, Australia. While Macquarie Harbour is grossly polluted from mine operations via contamination of the King River, Bathurst Harbour is surrounded by World Heritage wilderness and is essentially free of anthropogenic influences. The vegetation of the catchments of both harbours is similar and the waters of both harbours are deep brown due to the presence of humic substances. A hydrographic survey of the pristine Bathurst Harbour estuarine system was carried out over 4 days in January/February of 1990 (Austral Summer). Sampling and laboratory analyses for a range of trace elements (Cd, Co, Cu, Fe, Mn, Ni, and Zn) were made using non-contaminating procedures.

巴瑟斯特港（Bathurst Harbour）与麦夸里港（Macquarie Harbour）均为澳大利亚塔斯马尼亚西海岸的河口系统。其中麦夸里港因金河（King River）受到矿业活动带来的污染，已遭到严重污染；而巴瑟斯特港四周环绕世界遗产荒野，基本未受人为活动影响。两港流域的植被特征相似，二者水体均因腐殖物质（humic substances）的存在而呈现深褐色。1990年1月至2月（澳大利亚夏季），研究人员对处于原始状态的巴瑟斯特港河口系统开展了为期4天的水文调查（hydrographic survey）。本次研究采用无污染操作流程，对镉（Cd）、钴（Co）、铜（Cu）、铁（Fe）、锰（Mn）、镍（Ni）及锌（Zn）等多种微量元素完成了采样与实验室分析。
