Ecological state assessments of coastal areas are a worldwide important task in management of the coastal environment. The present study is focused on analysis of key patterns of elemental concentration levels in aquatic organisms/biomonitors from a model coastal area of the Black Sea at the Taman peninsula. The objects of research were seawater and freshwater, bottom sediments, coastal soils and macrophytes (algae and aquatic plants) of the Krasnodar Region, RF, (Cystoseira barbata, Cystoseira сrinita, Cladophora seriace, Ulva rigida, Polysiphonia elongata, Enteromorpha intetinalis, Ceramium rubrum, Padina pavonica, the species of higher hydrophytes: Zoostera noltii, Zoostera marina, Zannichellia palustris, Ruppia cirrhosa, Stuckenia pectinata, Potamogeton pectinatus, Phragmites communis, Carex and Ceratophyllum demersum) which were collected at different distances from the coast. Three complementary analytical techniques: neutron activation analysis (INAA), atomic absorption spectrometry (AAS) and X-ray fluorescence analysis (XRF) were used for determination of concentrations of 10-15 macro and 20-25-trace elements. The study confirmed the uniformity in the character of concentrations / dispersion of elements by bottom sediments in the model zones of the Russian Black Sea coastline, regardless of the increase in distance from the coastline. All biomonitors showed their own specificity in the accumulation of mineral elements. Similar patterns of concentration and dispersion were found for different morphophysiological parts of macrophytes (root system and suprabottom green part) of all studied species. Sites of background, polluted and in moderate pollution state among analyzed sites of the Russian coastal zone were proposed. The observed key patterns of elemental accumulation in aquatic plants-biomonitors, bottom sediments, and soils may be used in the future coastal environmental management and special ecological studies.
