The main aim of study was to develop the environmental quality standards (EQS) for selected heavy metals: Pb, Cd, Hg and Ni bioaccumulated in the tissues of marine macrophytobenthic plants: Chara baltica, Cladophora spp., Coccotylus truncatus, Furcellaria lumbricalis, Polysiphonia fucoides, Stuckenia pectinata and Zanichellia palustris, collected in designated areas of the southern Baltic Sea in period 2008-2015. The calculated concentration ratios (CR), which attained very high values: 10Lkg for lead, 10Lkg for nickel and mercury and even 10Lkg for cadmium formed the basis for the determination of EQS values. The EQS values were: 26mgkgd.w. for Pb, 33mgkgd.w. for Cd, 32mgkgd.w. for Ni and 0.4mgkgd.w. for Hg. The application of macrophytobenthic plants as bioindicators in marine environment status assessment of certain areas of the Baltic Sea is also described in the paper.
本研究的主要目的是为选定的重金属制定环境质量标准（EQS）：在 2008 年至 2015 年间，在波罗的海南部指定地区采集的海洋大型底栖植物组织中生物积累的 Pb、Cd、Hg 和 Ni，包括北海藻（Chara baltica）、叶状枝（Cladophora spp.）、短沟蜷（Coccotylus truncatus）、海韭菜（Furcellaria lumbricalis）、泡叶藻（Polysiphonia fucoides）、刚毛藻（Stuckenia pectinata）和扁浒苔（Zanichellia palustris）。计算出的浓度比（CR）非常高：铅为 10Lkg，镍和汞为 10Lkg，甚至镉为 10Lkg，这为确定 EQS 值提供了依据。EQS 值分别为：Pb 为 26mgkgd.w.，Cd 为 33mgkgd.w.，Ni 为 32mgkgd.w.，Hg 为 0.4mgkgd.w.。本文还描述了将大型底栖植物作为波罗的海某些地区海洋环境状况评估的生物指标的应用。
