“…This area is characterized by an increase in the water salinity from the surface to the bottom and seawards, with a pronounced wedge of salt water penetrating relatively far upstream from the river mouth. The pH value at the sampling site was 8.42 (Boltachev et al 2010), and the mean TRIX value in Sevastopol Bay was 4.01 (Slepchuk et al 2017), which corresponds to the moderate trophic level.…”

The mussel M. galloprovincialis is one of the most popular species in world's mariculture and environment pollution bioindicators. Although this mollusk was in a focus of numerous publications, the detoxifying and accumulating role of some of its body parts was insu ciently studied. In the present work, using inductively coupled plasma mass spectrometry, the distribution of Cr, Co, Ni, Cu, Zn, As, Cd, Hg, Pb in soft tissues, byssus, and shell liquor of this bivalve was studied for the rst time as a function of sampling location in the Black Sea off southwestern Crimea. Multivariate analysis showed signi cant differences in the overall distribution of the elements among the body parts and sampling sites under consideration. Human health risks from the consumption of this mollusk were shown to be unlikely. Byssus of M. galloprovincialis was characterized as an ideal indicator of marine environment pollution with Ni, Cu, Pb, Сo, and Cr as it contained the highest contents of these elements among the body parts under study (Ni up to 91%, Cu and Pb up to 79%). For the rst time, the concentrations of trace elements were determined in the shell liquor and its role as the trace element excretion system was demonstrated. In the shell liquor, the largest share among the body parts was that of Hg (up to 71%). In soft tissues, Zn, Cd and As were in largest proportions among the body parts (63, 62, and 54%, respectively). The trace element contents in soft tissues of M. galloprovincialis decreased in the following order: Zn > Cu > As > Ni > Pb > Cd > Cr > Co > Hg.

“…Tingkat kesuburan yang tergolong tinggi di perairan pesisir Desa Mantang Baru diduga disebabkan adanya aktivitas pemukiman dan masukan nutrien dari sekitar pesisir. Fosfat, nitrat, dan oksigen terlarut merupakan tiga unsur senyawa kimia yang sangat penting untuk mendukung kehidupan organisme dan penentu tingkat kesuburan dalam suatu perairan (Slepchuk et al, 2017). Secara alami ketiga senyawa kimia ini terdapat dalam air laut pada kadar yang sesuai.…”

The village of Mantang Baru which is lcoastal area, located in the district of Mantang. The objective of this study was to analyze the trophic status of the Mantang Baru village, subdistrict of Mantang, Bintan regency. The reserch was conducted by survey method, sampel observation using random sampling at 15 sampling points. Analysis of trophic levelwas used the TRIX index. The results of supporting parameters namely physics, chemistry, and biology of he water have met the water quality standards based on PPRI no.22 years of 2021 attachment of 8 the expect NO3 and PO4. The results of the measurement of chlorophyll-a content in the waters of the village of mantang baru at high t ide was 0,094µg/L at low was 0,089µg/L, the resutls of water based on TRIX at high tide ranged from 5,16 mg/L at low tide ranged from 5,87mg/L. Based on category TRIX the waters of the village of Mantang Baru are classified as eutrophic waters.

“…Due to the recreational development of Sevastopol, the presence of nature conservation facilities such as dolphinariums and mariculture development zones, there is a need to increase the requirements for compliance with sanitary standards in the region. Therefore, special attention is paid to the study of the ecological state of the Sevastopol Bay [1][2][3][4][5][6][7].…”

The aim of the present paper is to solve the problem of choosing the localities in the Sevastopol Bay for optimal placing the pollution sources using the adjoint equations of the admixture transfer. Methods and Results. The embankments in the city center, the Artilleriyskaya Bay and the city beach zone are chosen as the nature protection areas. Solution of the adjoint equation of the passive admixture transport yields the influence function that permits to reveal the areas on the coast, where, in case the pollution sources are placed there, the sanitary standards will be violated, and, at the existing structure of currents, these nature protection zones will suffer significant damage. To make sure that the adjoint equation is solved correctly, the direct problem can be solved for various locations of the impurity sources. Solution of the adjoint equation makes it possible to obtain information on the impurity amount in the preset nature protection zones during the preset time period at an arbitrary location of the impurity source. The currents velocities are calculated by the linear three-dimensional barotropic model for the steady wind currents. Conclusions. The numerical modeling results revealed the regions, where placing of the pollution sources would violate sanitary standards in the nature protection zones under study. The experiments showed that the north and east winds were the most dangerous. Hence industrial facilities, storm and sewage discharges having been placed at the Northern side of the Sevastopol Bay, can be extremely harmful for the ecological state of the regions under consideration. At the east and southeast winds, the industrial activity products in the Yuzhnaya Bay constitute a basic source of contamination. At the south winds, the most dangerous situation occurs in case the pollution sources are placed at the coast of the recreational zone of the city.
