Ecological and biogeochemical monitoring of the state of the landscapes of the Tsemesskaya Bay studied changes in the content of a number of metals in the most common algae. Sampling was conducted annually in spring and summer. To increase the reliability of the data, information was processed on a specially compiled map of aquatic geochemical landscapes. During the period under study the highest concentration of the majority of studied metals in algae was registered in 1998. This is most likely due to previous pollution of the bay, when almost all enterprises of Novorossiysk were still operating. Minimum concentrations of metals in algae are typical for 1999. In 2000 metal concentrations started to increase again.
An environmental-geochemical study was carried out for the landscapes of the Black Sea coast, dividing the territories into regions according to the nature and degree of technogenic impact. A map of geochemical landscapes of Tsemesskaya Bay was drawn up. For the purpose of their biogeochemical assessment, some species of laurel, kelp and green algae growing in the coastal zone were analyzed to determine the concentrations of 20 chemical elements in their ashes. Some elements (Pb, Mn, Cu, Co) characterized by predominant accumulation in cystosira with significant general pollution of coastal areas of the bay were identified. In 1999 there is a slight decrease in the concentrations of some elements in the ash of the studied algae compared to the previous year. In 2000, some increase of element concentrations in ashes of the observed algae was observed.
