title: Marine environment status assessment based on macrophytobenthic plants as bio-indicators of heavy metals pollution.
abstract: The main aim of study was to develop the environmental quality standards (EQSMP) 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: 104Lkg-1for lead, 103Lkg-1for nickel and mercury and even 105Lkg-1for cadmium formed the basis for the determination of EQSMPvalues. The EQSMPvalues were: 26mgkg-1d.w. for Pb, 33mgkg-1d.w. for Cd, 32mgkg-1d.w. for Ni and 0.4mgkg-1d.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.
