The macroand micro-element content in a homogenate of macrophytes was studied. Hydrochemical investigation of the littoral waters and surface and deep layers of the soil in the recreational areas of the Tiligul estuary was carried out. In red algae-macrophytes, a high correlation was noted between the following parameters: potassium and sodium; potassium and calcium; potassium and magnesium; sodium and chloride; calcium and chloride; and magnesium and chloride. A very high correlation between potassium and chloride was also noted. In green algae-macrophytes, there is a high correlation between indices such as: phosphorus and iron. We found that the biomass of algae-macrophytes across five recreational areas was highest in the «Atamanskaya Kosa» sector, both in the composition of macrophyte species and their biomass, while the lowest was observed in the «Tashinskoe» recreational area. We conducted complex measurements in the spring season, which allowed us to establish the ecological status of Tiligul estuary coastal waters.enmacrophyteecolodical monitoringlittoral watersmacro– and micro– elementred and green algaeTiligul estuaryArticle
