Abstract

The algae geochemical anomaly coefficient (K_GA) and hazard coefficient (K_Me), which are geochemical coefficients characterizing the condition of an algae habitat, have been calculated based on heavy metal (Fe, Mn, Cu, Zn, Pb, Cd, and Ni) levels in the brown alga Sargassum miyabei sampled at different time intervals from 49 stations in Peter the Great and Kievka bays, Sea of Japan. It has been found that K_Me > 1 occurs for K_GA > 2. A sketch map of the degree of metal contamination of algae in Peter the Great Bay has been compiled. At 22% of stations, algae show increased threshold levels of metals, which means that the ecological condition of these areas requires monitoring and measures to mitigate the environmental impact.

利用褐藻Sargassum miyabei在日本海彼得大帝湾金属污染的空间评估

摘要

基于重金属（Fe，Mn，Cu，Zn，Pb，Cd和Cd）计算了藻类地球化学异常系数（K _GA）和危害系数（K _Me），它们是表征藻类栖息地状况的地球化学系数。 Ni）在日本海的Peter the Great和Kievka海湾的49个站点以不同的时间间隔采样的褐藻Sargassum miyabei中的水平。已经发现，ķ_我> 1为发生ķ _GA> 2.绘制了彼得大湾中藻类金属污染程度的示意图。在22％的站点中，藻类显示出较高的金属阈值水平，这意味着这些区域的生态状况需要监测和采取措施以减轻对环境的影响。
