STUDIES REGARDING POLLUTING AGENTS IN BLACK SEA ALGAE

The capitalization of marine resources for therapeutic purposes is a desideratum which can bring about numerous advantages. Black Sea algae represent an important marine bioresource. They have represented an object of study in numerous published papers. The main prerequisite condition for the use of algae as a marine bioresource is the absence of contamination by polluting substances. The present paper studies polluting agents heavy metal content with a potential toxic effect (Pb, Cd, Cu and Zn). The method for heavy metal content determination was atomic absorption spectrometry. The studied algae included Cystoseira barbata, Ceramium rubrum, Ulva lactuca, Enteromorpha intestinalis, and Cladophora vagabunda, harvested from the Black Sea during June-August in two different years: 2016 and 2017. Comparisons in what regards the heavy metal content between the two years were made. The results obtained outline the low level of pollution of the algae biomass studied, in what regards heavy metal content.
