DYNAMICS OF POLLUTION OF THE ARDON RIVER WATER POOL (REPUBLIC OF NORTH OSSETIA-ALANIA, RF) WITH BURIED INDUSTRIAL WASTE FROM THE SADONSKY LED-ZINC COMBINE (SLZC) AND MINE WATERS

The article presents the generalized results of chemical composition research of waters from Inhulets and Saksahan rivers on the territory adjacent to the Northern and Inhulets with pumping of underground waters (mine and quarry), which have an abnormal chemical composition, high mineralization and contain high concentrations of microcomponents. The following scheme of mine water utilization is used in the Kryvyi Rih iron ore basin: the mines of the northern part of Kryvbas discharge water into the tailings dam of Northern Iron Ore Dressing works (Northern GZK); mines of the southern part discharge mine waters into the storage pond of the Svistunov creek during the year, and in the winter its waters are discharged into the Inhulets River with subsequent washing of the river in the spring-summer period. Such treatment of mine and quarry waters has led to the formation of a hydrochemical anomaly on the territory of Northern GZK with the center in the tailings. The mineralization of water in the pond reaches 23 g / l (2020). There is a high content of microcomponents: lead, cadmium, vanadium, manganese, boron, bromine, nickel, mercury, thiocyanates. As a result, the mineralization of the Saksahan River water increases over time (up to 5.4 g / l), the content of microcomponents also increases and becomes quite high. Prolonged use of the Inhulets River for utilization of mine water from the Svistunov creek storage pond has led to a change in the type of water: instead of type II (river water), Inhulets water belongs to the type III (metamorphosed waters). There are no regularities in the change of chemical composition of water (hydrochemical regime) in Inhulets, which is a consequence of the introduction of the scheme "discharge – flushing" for the disposal of mine water. Among the microcomponents in the water of Inhulets there is an increased content of vanadium, boron and bromine (7–8 times), single excess of lead content. The analysis of equilibria in the carbonate-calcium system of the Inhulets and Saksahan rivers confirmed that the existing hydrochemical regime for the studied rivers is stationary, thus, the environmental measures implemented will not have rapid consequences.

Strategic Role

Kondisi sungai Brantas Kota Surabaya semakin memprihatinkan akibat pencemaran dari limbah rumah tangga maupun limbah industri. Sebagai pemasok bahan baku PDAM, kualitas sungai Brantas harus diperhatikan sehingga tidak menimbulkan kerugian bagi masyarakat pengguna air. Letak sungai yang berada di kawasan hilir menjadikan beban pencemaran yang dialami sungai Brantas semakin berat serta lemahnya pengawasan dan penegakan hukum juga ikut mempengaruhi penurunan kualitas air sungai Brantas. Penelitian ini dilakukan untuk menunjukkan peran strategis Dinas Lingkungan Hidup Kota Surabaya dalam pengendalikan pencemaran air sungai Brantas baik dalam pengeluaran izin, pengawasan, pemberian sanksi maupun upaya dalam penanggulangan pencemaran. The condition of Brantas river in Surabaya is deteriorating as a result of contamination from household as well as industrial waste. As the provider of water for municipal fresh water supply service, the quality of Brantas river must be considered so as not to cause harm to the water users. The river part which is located in the downstream region makes the pollution even more severe. This condition is worsened by the lack of scrutiny and law enforcement efforts which ultimately also cause the degradation of the water quality of Brantas river. This study was performed to demonstrate the strategic role of the Environmental Office of Surabaya Municipality in controlling Brantas river water pollution in terms of the issuance of licenses, supervision, implementation of sanctions and measures taken to prevent water pollution.

Indirect Impact

Cikapundung River, Bandung is headed from Bukit Tunggul. It is flowing down to the residential area of Bandung. Based on biological and chemical analysis, this river has been polluted due to domestic and industrial waste. So far, impact on human health due to this water pollution has not known. In order to obtain an information on human health, descriptive analysis including questionnare and intervieuw has been carried out at five study locations of Cikapundung Riveer (Bukit Tunggul, Maribaya, Babakan Siliwangi, Babakan Ciamis and Bojong Soang). The result from this study that respondents living at Bukit Tunggul, Maribaya and Babakan Siliwangi get the water from water supply and well. The three latest locations are polluted (Surtikanti, et al, 2002). They are not aware using river water for their essential need. However, their human health has to be paid attention, because diarrhoea, skin disease and fever dengue that related to water pollution were experienced by respondents. It indicates that water pollution of Cikapundung River has indirect impact to environmental health.Keywords: human health, water pollution, Cikapundung River, domestic- industrial waste.

Copper Mines

Through this study special attention was paid to AMDs, originating from copper mines, containing different heavy metal ions, and a certain amount of sulphuric acid. The research was conducted on the territory encompassing the RTB Bor mines (now Serbia Zijin Bor Copper). The AMDs occurrences, their water composition, metal potential, and impact on the local surface waters were determined. The major amount of mine waters flow into the Krivelj River damaging extremely its water quality. The research also included monitoring the Timok river water quality along its course from the Krivelj River inflow to the confluence with the Danube. Evaluating the metal losses, it was found that every year around 360 tons of copper, >500 tons of iron, and 30 tons of zinc from mine waters are lost, as being transported via the Krivelj River to the Timok and then to the Danube.

Abstract The aim of the study was to determine the influence of coal mine waters on water quality in the Vistula River. Water samples for laboratory analysis were collected in 2011 and 2012 on one kilometer long section of the river. Basic parameters were measured at the collection spot. The study asseses the dynamics of physicochemical water properties, fulfillment of the quality requirements necessary to introduce contaminated water into the river, water salinity, quality, and utility values. The study indicates that water quality of the Vistula River has been rapidly decreasing as a result of coal mine water introduction. Water becomes degraded, unfavourable for fish communities and unsuitable for use by people. Coal mine water contamination exceeds allowable pollution levels stated by legal regulations. Self-purification of the river is efficient as contamination levels decrease at the length of the examined section of the river.

Fingernail Clams

Fingernail clams (Muscu1ium transversum) are dominant bottom-dwelling animals in some waters of the midwest U.S. These organisms are key links in food chains leading from nutrients in water and mud to fish and ducks which are utilized by man. In the mid-1950’s, fingernail clams disappeared from a 100-mile section of the Illinois R., a tributary of the Mississippi R. Some factor(s) in the river and/or sediment currently prevent clams from recolonizing areas where they were formerly abundant. Recently, clams developed shell deformities and died without reproducing. The greatest mortality and highest incidence of shell deformities appeared in test chambers containing the highest proportion of river water to well water. The molluscan shell consists of CaCO3, and the tissue concerned in its secretion is the mantle. The source of the carbonate is probably from metabolic CO2 and the maintenance of ionized Ca concentration in the mantle is controlled by carbonic anhydrase. The Ca is stored in extracellular concentric spherical granules(0.6-5.5μm) which represent a large amount of inertCa in the mantle. The purpose of this investigation was to examine the role of raw river water and well water on shell formation in the fingernail clam.
