scholarly journals River Runoff Impact on the Taganrog Bay and the Kuban River/Azov Sea Coastal Waters Quality

Author(s):  

The low-depth Azov Sea coastal waters quality has been investigated. The sea faces considerable human-originated loads caused by the different origin pollutants river runoff. The river runoff pollutants comprise petroleum products, synthetic surface-active substances, phenols, chlorinated hydrocarbons, and heavy metals. Results of the investigation intended to affirm the suppositions on possibilities of the Azov Sea Temryuk Bay and Taganrog Bay coastal waters quality forecasting with the use of limited hydrological and hydro/chemical information obtained from the control stations have been presented. Comparison of the most significant water quality characteristics of river runoff and sea water has confirmed such a possibility. Further studies will be aimed at founding of the correlation dependencies for the most hazardous pollutants.

Aim. Currently, oil pollution remains one of the primary pollutants of the marine environment. This is especially true for the Black Sea and Azov Sea which experience significant anthropogenic pressure. The study presents the results of two-year monitoring studies of the content of oil hydrocarbons in the surface and bottom horizons of the coastal waters of the Azov-Black Sea regions of Russia.Materials and Methods. The determination of oil hydrocarbons was conducted by infrared spectrometry using a FSM-1201 Fourier spectrophotometer with preliminary transmission of the extracts through a chromatographic column with aluminum oxide. The work was carried out as part of five scientific expeditions (93th, 96th, 100th, 102nd and 105th) of the research vessel, Professor Vodyanitsky, in 2017 and 2018.Results. The general environmental status for this pollutant is characterized as stable, despite in some cases being 3 to 4 times in excess of established standards (MPC). Separate foci of localized oil pollution have been identified and vulnerable areas of the sea coast of southern Russia have been identified. An excess content of petroleum hydrocarbons in the surface layer compared to the bottom layer was noted, which indicates a surface path of entry of petroleum products into sea water.Conclusion. Currently, the coastal waters of the western part of Crimea are most affected by oil, primarily associated with the runoff of European rivers and the peculiarities of the marine hydrological regime, including the Kerch Strait, an area of heavy shipping traffic. The Caucasian coast is less affected by oil pollution than the Crimean. Despite the fact that currently the content of oil hydrocarbons in sea water is far from the quantities dangerous to humans and aquatic organisms, monitoring of this indicator is vital due to the increasing anthropogenic pressure on the recreational zones of the Crimean and Caucasian coasts of the Russian Federation.

Coastal areas play a crucial role in maintaining the ecological balance of ecosystems and developing the social and economic wellbeing of the countries bordering it. However, the pressure on both terrestrial and marine resources, the use of oceans as a wastes deposit, the growth of population and the increasing of urbanization and human activities in coastal areas are all causes for marine and coastal degradation. The present situation constitutes a significant danger in many places. As an example, the pollution of the coastal waters in the Mediterranean has increased in recent years. Industrialization, tourism and ports activities along the coastline of the Mediterranean are the main sources of many pollutants that have effects on human’s health and environment. So that, it is very important to examine seawater quality in order to protect the marine and coastal areas from degradation. Hence, comes the need to consider a physicochemical and bacteriological study to evaluate the quality of Tangier coastal seawater using the Water Quality Index (WQI). A campaign of 25 sampling points was conducted and the results of the WQI calculation have highlighted the Tangier water was between medium and bad.

Fresh groundwater quality and accessibility in coastal zones is influenced via seawater interruption into coastal aquifers, and coastal water quality and biological community status might be altogether influenced by groundwater pollutants that are transported into coastal waters by submarine groundwater discharge (SGD). SGD and its pertinent evaluation as one associating part  among the different principle local pathways of freshwater and tracer/poison contributions from land to sea and the coordinated framework working of both and as primary segments of the same coastal groundwater framework. An elective technique might be to control seawater interruption through fake groundwater revive, for example by adequately treated wastewater, which may impressively decrease long haul patterns of saltiness increment in pumped groundwater, notwithstanding for little simulated energize rates contrasted with pumping rates. Both the outside sources and the interior wellsprings of water seepage might be distinguished via doing infrared thermo-realistic assessments subsequent to directing water snugness tests, flooding tests or pressure driven tests as suitable. A contextual investigation was led to discover the examinations on groundwater issues in a region subjected to sea water ingression and seepage into groundwater in Karaikal

The number and size of colonies found in bacterial counts of sea water collected from the Menai Straits varies with the concentration of peptone in the medium. The optimum concentration of peptone was found to be 0.3%. Neither yeast extract, beef extract or added iron increased the count when added to media made from Menai Straits water. The effect of various temperatures on the count, and the relative merits of pour plates and surface growth techniques were examined. Vigorous shaking, or passage through a Sharpies centrifuge, was found to increase the count.
