Agardh in the littoral zone of Sevastopol (Black Sea) JF - Marine Biological Journal JA - mbj VL - 2 IS - 2 SE - Scientific communications DO - 10.21072/mbj.2017.02.2.05 UR - https://marine-biology.ru/mbj/article/view/76 SP - 49-54 AB - <p>The coastal zone of Sevastopol, especially the recreational part, feels great anthropogenic impact due to hosting a large number of tourists, but also because of the urban and stormwater discharge, containing oil hydrocarbons in its composition. Brown algae <em>Cystoseira</em> <em>barbata</em> forms vast underwater thickets here. Cut off from the substrate algae are at the edge of the water, mixed with coastal casts, resulting in secondary pollution of both coastline and coastal waters. At the same time freshly detached plants are used by representatives of different taxonomic groups and are actively involved in the food chain. In this context, the aim of this work is to study the lipid-hydrocarbon composition of <em>Cystoseira</em> from the coastal storm casts. The amount of oil hydrocarbons was determined by gravimetric method and the amount of lipids by color reaction with phospho-vanillin reagent. The results obtained indicate higher levels of chloroform-extracted substances, total lipids and oil hydrocarbons in macrophytes of Kruglaya Bay in comparison with the levels in water area of Park Pobedy. Onshore casts of <em>Cystoseira</em> may be the source of secondary pollution of the coastal waters by oil hydrocarbons.</p> ER -
