Knowledge of environmental pollution with an impact on health is essential for a sustainable environment and useful for people. The coastal areas of the world�s seas and oceans are polluted with different pollutants from technological sources and from other sources of socio-human activities. The pollutants studied are heavy metals Cd, Cu, Zn and Pb. In the paper are presented researches regarding the heavy metal concentrations determined in samples from marine water, sediments and algal mass, harvested from six stations from different areas of the Romanian Black Sea in two different years 2017 and 2018. The analyses were performed in the Chemistry Laboratories of the Faculty of Pharmacy, Ovidius University in Constanta, by a spectrophotometric method using Atomic Absorption Spectrometer ContrAA-700, Analytic Jena AG. For marine water in 2018 the following concentrations were obtained: Zn ] Pb ] Cu ] Cd and in 2017 the order was different: Zn ] Cu ] Pb ] Cd. For sediments in 2017 the order of concentrations is Cu ] Zn ] Pb ] Cd and in 2018 the highest values in the sediment are recorded by the next high values Cu ] Pb ] Zn ] Cd. Constant climate change and increased eutrophication in recent years have led to a massive increase in marine biomass in the Black Sea. For seaweed samples there are accumulations in the order of Zn ] Cu ] Pb ] Cd in both years. Bioaccumulation factors in water BCF water, were higher in algae for Zn and Cu. From the analysis of bioaccumulation factors, it can be noticed that seawater algae accumulate heavy metals from seawater and sediment (confirmed by BCF water ] 1 or BCF sed. ] 1). The accumulation of heavy metals in seaweed shows the existence of pollutants and marine pollution factors. Marine algae are the best biomarkers of pollution.

In the Turkish Black Sea coasts fish is particularly consumed because of high protein supplies, essential amino acids, vitamin, and mineral content. Fish are exposed to contaminants such as heavy metals in polluted waters. The aims of the study are to determine heavy metals in Pleuronectiformes species from Sinop coasts of the Black Sea and determine the health risks due to the consumption of contaminated fish. Pleuronectiformes species Scophthalmus maximus (Linnaeus, 1758) belonging to Scophthalmidae family, Arnoglossus laterna (Walbaum, 1792) belonging to Bothidae family and Pegusa lascaris (Risso, 1810) belonging to Soleidae family were collected from Sinop coasts of the Black Sea in fishing season of 2016. Heavy metals (Hg, Cd, Pb, Cu and Zn) in edible tissues were determined by ICP-MS (Agilent 7700x). The limit values given by the international and national organizations did not exceed in the muscle tissues of turbot, Mediterranean scald fish and sand sole. Overall Zn was detected in higher concentrations in all species followed by Cu, Pb, Hg and Cd. The results obtained from the analyses of the maximum levels of the metals except Hg were found in turbot. The highest Hg (0.021±0.007 µg g-1 wet wt.) was found in sand sole. However, the high amounts of Cd, Pb, Cu and Zn in turbot were 0.011±0.004, 0.07±0.005,1.32±0.28 and 14±3 µg g-1 wet wt., respectively. The EDIs and EWIs of the metals were estimated taking into account the mean of metal in all fish samples and the mean consumption of fish per day/week for adults. These results are normally significantly lower than the recommended values of FAO/WHO. Estimated HIs of all the considered metals were below the value of 1, therefore the metals in fish samples do not toxic any apparent threat to the population and these fishes are healthy for consumption.Keywords: Scophthalmus maximus, Arnoglossus laterna, Pegusa lascaris, heavy metals, Black Sea

In the Bulgarian part of the Black Sea coast there are seventeen rivers and three lakes which contribute to the pollution and eutrophication of the Black Sea. The hydrophysical and hydrological characteristics of these rivers are described. The variation in the concentration of heavy metals during recent years (data up to 1996) has been determined. The total annual quantity of some pollutants and their percentage distribution are presented. Conclusions are made based on the variation of water quality of the rivers and their impact on the heavy metal pollution of the Black Sea.

Sediments are an important repository for various pollutants such as pesticides and heavy metals and also play a significant role as sensitive indicators for monitoring contaminants in aquatic systems. Heavy metals which are regarded as serious pollutants of aquatic ecosystems are a major environmental problem in the Black Sea. Contamination by heavy metals has not been extensively studied in the Black Sea coast of Turkey, even though these are subjected to intense discharges of pollutants. It is important, therefore, that sediment by heavy metals be assessed in order to facilitate better management and protection of these valuable coastal ecosystems. This is especially the case, since Turkish Black Sea coast represents a prominent area for fishing, industrial development and urban extension and tourism activities. In view of the economic importance of the Black Sea coastal region of Turkey, this review aims to analyses the distribution and concentrations of heavy metals in bottom sediment in the coastal sediment along the Black Sea.
