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.

The aim of our investigation is a survey of heavy metal pollution in algae, sediments and water from the Bulgarian Black Sea coast and determination of algae species appropriate as bioindicators. The levels of iron, copper, manganese, zinc, lead and cadmium are determined in water, sediments and eight species of macroalgae: (four green: Cladofora laetevirens, Ulva rigida, Enteromorpha intestinalis and Bryopsis plumosa; two brown: Cystoseira crinita and Cystoseira barbata; and two red: Ceramium rubrum and Corallina mediterranium), widely distributed in the Bulgarian coastal zone, and dominant in the Black Sea. The studied area is the littoral coastal zone from four locations - Tuzlata, Ravda, Ahtopol and Sinemoretz. No significant variations between metal concentrations in algae samples are obtained, while for sediments and water there are significant differences between location and season. The Cladofora laetevirens and Ceramium rubrum species show the highest metal content while Cystoseira crinita and Cystoseira barbata show the lowest level. The correlation coefficients and concentration factors of the elements are calculated.

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.

Creation of infrastructure for coastal sea passenger transport and yachting along the Black Sea coast of Russia is one of the important direc-tions of development potential of coastal cities. This infrastructure will al-low increasing significantly quality of the recreation, to diversify tourist ac-tivity (tourism, hotel business, etc.). Creation of modern yacht-harbors, re-construction and development of port piers for coastal passenger transport will allow increasing in essence quality of tourism and developing touristic activity in the region. The basic principles are defined for the analysis of re-quirements and existing conditions of the territory and the prospects of de-velopment of the Russian coast. They take into account all aspects of func-tioning of yacht-harbors and port piers as one of the most important ele-ments of development of seaside city.
