A mathematical approach to groundwater quality and pollution of Adyar sub-basin, Tamil Nadu, India

The quality of drinking water sources in the Adyar river sub-basin of northern Tamil Nadu is assessed in this study. This research uses a combined water quality index (WQI) and pollution index (PI) to assess and characterise groundwater quality. Water samples will be collected from nine locations in the study area for the assessment. The water quality index was calculated based on Total Dissolved Substances (TDS), Nitrogen oxides (NOx), Calcium (Ca), Magnesium (Mg), Sodium (Na), Potassium (K), Chloride (Cl), Sulphate (SO4), Bicarbonate (HCO3), Fluoride (F), Power of Hydrogen (pH) and Electrical Conductivity (EC). These twelve parameters were analysed and characterised according to standard methods and the Indian standard, which were then used in calculating the water quality index. Groundwater quality and pollution status of the Adyar river basin were assessed using the Groundwater quality index and comprehensive pollution index for the years 1990, 2005, and 2020. A result reveals that the groundwater quality has decreased from 1990 to 2020. Around seven parameters exceeded the permissible limits in 1990, nine parameters exceeded the permissible limits in 2005, and around eight parameters exceeded the allowable limits in 2020. The pollution status of the groundwater has considerably reduced from 1990 to 2020. Eastern parts of the study area were highly polluted and had low groundwater quality.

Diversity of Antibiotic-Resistant <i>Escherichia coli</i> from Rivers in Palembang City, South Sumatra, Indonesia

<abstract> <p>One of the indicators of water pollution is the presence of coliform bacteria, such as <italic>Escherichia coli (E. coli)</italic>. The development of resistance properties to several antibiotics by this pathogen is a serious health problem. Therefore, this study aims to isolate and identify antibiotic-resistant <italic>E. coli</italic> using the 16S rRNA gene. Samples were taken along the Kedukan, PU, and Buah rivers in Palembang City, South Sumatra, Indonesia, using the purposive sampling method. Each river consists of 9 sampling points, namely, the lower, middle and the upstream regions. The water quality result for the three rivers show that several water quality parameters do not meet the water quality standards: namely, BOD levels in the Kedukan and Buah rivers, Fe levels in the Kedukan and PU rivers, and chlorine in the three rivers. The results showed that <italic>E. coli</italic> isolates from the Kedukan, PU and Buah rivers were sensitive to 9 antibiotics. The highest resistance (100%) of <italic>E. coli</italic> isolates to tobramycin was in the Kedukan and PU rivers, while those from the Buah river were resistant to ampicillin. The phylogenetic tree analysis showed genetic diversity. Two main groups were formed from <italic>E. coli</italic>, namely, A and B, which consist of 17 and 4 isolates, respectively. Furthermore, the water quality analysis results of the Kedukan, PU, and Buah rivers in Palembang City, South Sumatra, revealed that they are polluted.</p> </abstract>

Spatial and temporal variations of physical-chemical parameters of the Akor River in Ikwuano local government of Abia state, Nigeria

Abstract. Physical-chemical parameters of the Akor River were investigated. The river water was sampled for seven months (February August) in 2019 and analysed following standard procedures and protocols. The results revealed that there were no significant differences (P > 0.05) among all the investigated physical-chemical parameters across stations. Mean values of all the investigated physical-chemical parameters were within Federal Ministry of Environment set standards (2011) except for chemical oxygen demand and pH. Spatiotemporal results revealed that turbidity, total suspended solids, total dissolved solids, and the major cations (Na+, K+, Ca2+, and Mg2+) as well as the major anions (PO43-, NO3- and SO42-), were high during the rainy season months, but water temperature, pH, dissolved oxygen, and biochemical oxygen demand were higher during the dry season months. The percentage of Na+ contents ranged from 15.85 to 16.39%, indicating that Akor River has excellent irrigation water quality. The Nemerow pollution index varied from 0.59 to 0.63, also indicating that the river water is of good quality. The water quality index results varied from 52.70 to 54.50%, indicating that Akor River has a good water quality status. The result of water pollution index revealed that Akor River status is excellent and capable of sustaining biodiversity as well as crop irrigation.

Water is one of the primary needs of every living creature. With the increase in population, the need for water continues to increase. The declining water quality caused by human activities is one of the world’s concerns. This study examines river water quality status in the gold mining area in the downstream of Krueng Kluet sub-watershed. The method used to determine the level of river water pollution is based on the Decree of Minister of Environment Number 115 the Year 2003, which uses class 1 water quality standards according to Government Regulation of The Republic of Indonesia Number 82 the Year. The results show that river water in the study area is in the category that is not polluted or fulfills water quality standards for drinking water and daily needs.

Analysis of Water Pollution Causes and Control Countermeasures in Liaohe Estuary via Support Vector Machine Particle Swarm Optimization under Deep Learning

This study explores the loss or degradation of the ecosystem and its service function in the Liaohe estuary coastal zone due to the deterioration of water quality. A prediction system based on support vector machine (SVM)-particle swarm optimization (PSO) (SVM-PSO) algorithm is proposed under the background of deep learning. SVM-PSO algorithm is employed to analyze the pollution status of the Liaohe estuary, so is the difference in water pollution of different sea consuming types. Based on the analysis results for causes of pollution, the control countermeasures of water pollution in Liaohe estuary are put forward. The results suggest that the water pollution index prediction model based on SVM-PSO algorithm shows the maximum error of 2.41%, the average error of 1.24% in predicting the samples, the root mean square error (RMSE) of 5.36 × 10−4, and the square of correlation coefficient of 0.91. Therefore, the prediction system in this study is feasible. At present, the water pollution status of Liaohe estuary is of moderate and severe levels of eutrophication, and the water pollution status basically remains at the level of mild pollution. The general trend is from phosphorus moderate restricted eutrophication to phosphorus restricted potential eutrophication. To sum up, the SVM-PSO algorithm shows good sewage prediction ability, which can be applied and promoted in water pollution control and has reliable reference significance.

Hydrobiological Studies and Zooplankton Diversity of Sagar Talao District Bhandara Maharashtra

Air, water, land, flora and fauna are the natural resources of any ecosystem. Water is very important for existence of life. It is the medium, which gave birth to first primitive living molecules,as the living organisms found in water are reliable indicators of water quality. The distribution and diversity of zooplankton in aquatic ecosystem depends mainly on the physic-chemical properties of water. For the study of water quality, the limnological observation is needed. Most of the organisms are being extensively used as indicators of water pollution. The biological indicators provide a direct clue and quick information of the aquatic systems. In present study, the zooplankton of the Sagar Talao was studied for a period of one year with its physico chemical factors. In present study total of 09 species of zooplanktons belonging to Rotifera, Ostracoda Cladocera, Copepoda, were present..

Regarding the choice of composite indicators of ecological safety of water in the basin of the Siversky Donets


 
 
 
 The lack of effective mechanisms of the methods of basin management, control of and responsibility for the ecological state of surface sources of drinking water leads to the fact that the main man-made objects that determine the ecological state of surface water sources are most often located in one oblast, while the production and consumption of the drinking water from those sources occur in the territory of other oblasts, which complicates the effective management of environmental safety of surface water sources. This is especially true for the regions of Ukraine which are poor in surface water resources, located in the basin of the Siversky Donets River, the water bodies of which are the main sources of water supply in the eastern regions of the country. The main consumer of water is Donetsk Oblast (over 50 % of the annual volume), and Kharkiv and Luhansk Oblasts together consume approximately the same volume of water per year (up to 50 % of the annual volume). Therefore, it is important to substantiate the integrated indicators of the ecological status of the water body to improve the environmental safety of surface water sources. The paper shows that oxygen indicators play an important role in the ecology of a water body. They are associated with the assimilative ability of water, the ability of water to decompose organic matter. Therefore, the content of dissolved oxygen and biochemical oxygen consumption in water is of great interest not only in terms of life development, but also as a composite measure of the ecological status of the aquatic environment. The relationship between the value of the combined index of water pollution and the value of biochemical oxygen consumption makes the indicator of biochemical oxygen consumption important for the integrated assessment of water contamination with various organic substances. For the tasks for which we justify the choice of composite measures of the ecological condition of surface waters, it is more important to identify the effects of contamination not directly at the site of contamination, but at some distance from it and after some time. Therefore, the use of the amount of dissolved oxygen and biochemical oxygen consumption as indicators that characterize the oxidation of pollutants present in water is the most appropriate for the tasks of timely monitoring of water bodies. Therefore, as a composite indicator for characterizing the condition of the watercourse and conducting timely monitoring, we chose oxygen indicators.
 
 
 

Study of the role of natural and anthropogenic factors in the formation of water quality in small rivers on the example of the Veletma river in the Nizhny Novgorod region

Small rivers of Central Russia often experience a high anthropogenic pressure, and at the same time their study and measures taken to preserve them are incomparably more modest than for large rivers. On the example of the Veletma river in the Nizhny Novgorod region, the factors affecting the formation of the water quality of the small river are considered. The ecological and geographical characteristics of the Veletma river are given. It is shown that the current methodology for assessing the water quality of large rivers by the Specific Combinatorial Water Pollution Index does not allow to determine what is the contribution of anthropogenic pressure to the deterioration of water quality, and what is the contribution of natural factors. Studies of a number of physical and chemical characteristics of the waters of the Veletma river have shown that on a short section of the river, which is less than 400 m, there are significant changes in the physical and chemical composition of water, reaching 45-95%. Such significant changes are associated on the one hand with the influence of the treatment facilities of the city of Navashino, and on the other hand, with the special location of the lake Zelenoe in the path of the river. Satellite images of the Veletma's confluence with the lake Zelenoe show the plume. It is suggested that the lake is characterized by the same processes that take place in the confluence of large and medium-sized rivers into the seas and lakes, called marginal filter, in which not only suspended but also dissolved impurities are retained. This fact is confirmed by laboratory studies.

Removal of cyanide from alumina smelter wastewater using precipitation and filtration technique

Aluminum is a metal that is used in many products because of its good conducting properties. However, in the production process, aluminum is not obtained easily but through a long process. In aluminum smelting process, wastewater that is produced indicates the existence of pollutants as determined by several indicators of water pollution, one of which is cyanide that will threaten human and environmental health if not treated properly. This study was conducted to determine the optimal dose of ferrous sulfate to remove cyanide, the precipitation and filtration process efficiency in reducing cyanide, and its effect on pH of wastewater. Data were collected from an aluminum smelting company, and experiments were conducted in the laboratory. Based on results, ferrous sulfate dose of 93 mg/l is the most optimal dose in removing cyanide with an efficiency of 58.74±0.51%, while filtration process provides an efficiency of 81.65±0.42%. Precipitation with ferrous sulfate makes pH value of wastewater decrease, but filtration process increases the value again. Throughout the whole process, cyanide can be reduced by a combination of precipitation and filtration process with the efficiency of 92.43±0.26% and an average final effluent concentration of 0.78 mg/L from an initial concentration of 10.3 mg/L.

In this study, 12 springs were discovered with Kasimpar spring having the highest discharge (5.01 liters/second). The overall condition of the spring ecosystem services is one of surplus water / carrying capacity has not been exceedee (Dda ratio > 1), and the condition appropriate with water quality standards (IP <1). In conclusion, this study plays an important thing to figure it out about the existence of water ecosystem services in this area, as well as being a pioneer study on Payment for Ecosystem Services (PES) model in Banjarnegara Regency with an integrated upstream-downstrean concept and based on the principle of sustainability

Kajian Kualitas Air dan Indeks Pencemaran Di Perairan Kampung Sejahtera Pulau Baai Kota Bengkulu

Water quality is one of the important factors supporting the growth of mangrove ecosystems. The activites of Kampung Sejahtera’s people were allegedly polluted the waters and disturbing the mangrove ecosystem. This study aimed to identify the status of water quality and pollution index in the waters of Kampung Sejahtera, Bengkulu City. The method used is a direct measurement at the research location which was carried out at 9 location points, 5 points representing the waters near the settlements of the prosperous village residents, and 4 location points representing the waters near the mangrove ecosystem. Then the results are compared with the Decree of the State Minister of the Environment No. 51 of 2004 concerning seawater quality standards for marine biota and to determine the status of water quality by using the pollution index method based on the Decree of the State Minister of the Environment No. 115 of 2003. The results of this study indicate that the temperature parameter, salinity, and pH met the quality standard while the TSS and DO parameters did not fulfill the quality standard. Based on the results of the calculation of the pollution index that the waters of Kampung Sejahtera are in the category of good condition to lightly pollute.

Significant impact of seasonality, verticality and biofilm on element accumulation of aquatic macrophytes

Submersed macrophytes accumulate large amounts of macro- and trace elements from the environment and, therefore, are frequently used as indicators of water pollution and tools to remove pollutants from contaminated waters. This study provides evidences that the quantity of macro- and trace elements accumulated in the macrophyte Ceratophyllum demersum depends strongly on the seasonality, on the vertical position of the plant material and on the biofilm cover. Element contents of macrophytes with and without biofilm cover and that of vertical plant sections were investigated by an ICP-MS technique in three different habitats, at the beginning and at the end of the vegetation period. Results demonstrated that the element concentrations of Ceratophyllum demersum dropped to one-half and one-eighth by the end of the summer; and the amount of certain elements in the lower part of plants were up to six times higher than in the upper and in plants with well-developed epiphytic microbial community 2-5-fold higher than in plants without biofilm.These results help in phytoremediation practice and in setting up future biomonitoring studies. When it is necessary to calculate the exact amount of elements which can be accumulated by plants in a polluted environment or should be removed from a contaminated water by harvesting macrophytes, it is of high importance to consider the month of the study, the plant parts harvested and the biofilm cover.

Monitoring the Landscape Pattern and Characteristics of Non-Point Source Pollution in a Mountainous River Basin.

This study aimed to assess the relationship between the landscape patterns and non-point source (NPS) pollution distribution in Qixia County, China. The sub-basin classification was conducted based on a digital elevation model and Landsat8 satellite images. Water samples were collected from each sub-basin, andtheir water quality during the wet and dry seasons was estimated. The correlation between the landscape indices and water pollution indicators was determined by Pearson analysis. The location-weighted landscape contrast index (LWLCI) was calculated based on the “source-sink” theory. Qixia was further divided into five sections based on the LWLCI score to illustrate the potential risk of NPS pollution. The results showed that the water quality in Qixia County was generally good. Cultivated land, orchards, construction areas, and unused land were positively correlated with the water pollution index and weredesignated as the “source” landscape categories, while forests, grasslands, and water bodies, which were negatively correlated with water pollution, were the “sink” landscapes; the LWCI was high in 36.94% of the study area. In these areas, measures such as increasing vegetation buffer zones are necessary to decrease the sediment and nutrient loads carried by precipitation.

Chemical and ecological quality of water and bottom sediments in small rivers of Belgorod oblast

Belgorod Oblast has limited water resources. The paper explores the chemical and ecological characteristics of water and bottom sediments in the Oskol River tributaries. In samples of water taken from small rivers, Maximum Allowable Concentrations (MAC) for pollutants was excessive, including suspended matter, ammonium ions, nitrite ions, phosphate ions, BOD5 and mineral elements. A hydrochemical water pollution index (WPI6) ranges from 1.0 to 1.9, which characterizes water bodies in the categories from clean to moderately polluted watercourses. A comparatively high WPI6 index is recorded in summer for the Kotel River – 1.4, for the Belenkaya River – 2.3, which is attributed to a high concentration of ammonium ions, nitrites and phosphates found to be present in the water. This indicates recent pollution and a changing trophic status of the reservoir. The amount of metals in river water exceeds the MAC norms: for iron – 1.7 -6 MAC; for copper – 1.6 - 8 MAC; for manganese – 0.8 - 22 MAC; for zinc – 1.9 - 9.9 MAC. Concentrations of micronutrients are subject to significant seasonal fluctuations. No excess of lead is found to be present in surface waters. In the samples of bottom sediments taken from the Oskol River tributaries, no excess of MAC values is found, except for lead (1.1 - 2.9 MAC), manganese (1.6 - 2.2 MAC), copper (1.2 - 1.6 MAC) and phosphate ions (1.3 - 2.3 MAC). It is obvious that the sources of pollution for small rivers are runoffs from agricultural land, livestock farms and household wastewater of nearby settlements.

ЭКОЛОГИЧЕСКАЯ ОЦЕНКА КАЧЕСТВА ВОДЫ УРБАНИЗИРОВАННОГО ПРИТОКА ОНЕЖСКОГО ОЗЕРА ПО ХИМИЧЕСКИМ ПОКАЗАТЕЛЯМ

Introduction. The Lososinka River is an urban tributary of Lake Onego, the lower reaches of which flow through the territory of Petrozavodsk city, receiving untreated drains of the city’s storm sewers. The river enters the Petrozavodsk Bay of Lake Onego, which is used as a source of public drinking water supply in the city. Methods. During the 2015 open water period, the oxygen concentration, total iron, color, pH, total suspended matter, biochemical oxygen demand (BOD5), content of oil products, and dichromate chemical oxygen demand were measured by standard methods in the water of the background and urban areas of the Lososinka River. Results. In the river water, high values of water color (132 mg/l Cr-Co), total iron (1.5 mg/l), dichromate chemical oxygen demand (23 mgO/l) were revealed, which is associated with the geochemical peculiarities of the surface waters in Karelia, enriched in the humic matter. Seasonal increases in the concentrations of these indicators were associated with floods. The oxygen saturation of the water reached 90% due to the fast current and riffles. The indicators of water pollution include total phosphorous (60 μg/l), mineral phosphorous (40 μg/l), BOD5 (1.5 mgO2/l), suspended matter (25.5 mg/l), and content of oil products (0.02 mg/l). Seasonal changes in these indicators were not associated with the hydrological regime of the river. In the storm sewers of the city, the maximum permissible concentrations for BOD5 are exceeded by 4 times, and for oil products — by 15 times. The Kruskal–Wallis test showed that all the studied chemical indicators in the urban and background areas of the river do not have significant differences. Conclusion. Water quality in the Lososinka River is considered satisfactory in terms of most of the studied parameters. According to the total iron content, the water is characterized as polluted, and according to water color, the river water is classified as dirty. The maximum permissible concentrations for total iron in the background and urban areas of the river were exceeded by 10 times. The standards for water quality adopted in the Russian Federation and the maximum permissible concentrations for total iron and water color are inapplicable for the water bodies in Karelia with high background values of these indicators. The trophic status of the river corresponds to the eutrophic state. Good saturation of the river water with oxygen hinders water pollution in the city territory due to self-purification processes.

ASSESSMENT OF RIVER WATER QUALITY IN THE CITY BY HYDROCHEMICAL INDICES (THE OKHTA RIVER, ST. PETERSBURG)

The Okhta River water quality was assessed in the period 2016–2020 using the component- wise assessment method and three hydrochemical indices (Water Pollution Index (WPI), Specific Combinatorial Water Pollution Index (SCWPI), and Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI)). The component-wise assessment demonstrated that the pH was neutral or slightly alkaline, and water hardness was low. Dissolved oxygen deficit was observed at most stations during the entire research period. The content of dissolved oxygen declined downstream along the river. At the river mouth, the oxygen situation is slightly better due to the inflow of the Neva River water. The BOD5 exceeded the MPC at all sampling stations, suggesting the Okhta River water was polluted with readily oxidizable organic matter. The iron content in the water exceeded the MPC manifold. An elevated content of various forms of nitrogen was also revealed. Over the entire observation period, increased concentrations of oil products were constantly recorded (exceeding MPC more than 50‑fold in different years). The Okhta River water was characterized as “dirty” and “extremely dirty”, and the water quality was “poor” according to the calculated values of the indices – WPI, SCWPI and CCME WQI. The methodology of the little-known in Russia CCME WQI is considered separately. It was compared with the WPI and SCWPI. The relationship between the indices is clarified. The use of CCME WQI for surface water quality assessment along with SCWPI is recommended.

Mechanism of action and toxicological evaluation of engineered layered double hydroxide nanomaterials in Biomphalaria alexandrina snails.

Layered double hydroxide (LDH) nanomaterials have recently become immense research area as it is used widely in industries. So, it's chance of their release into natural environment and risk assessment to nontarget aquatic invertebrate increasing. So, the present study aimed to synthesize and confirm the crystalline formation of Co-Cd-Fe LDHs and Co-Cd-Fe/PbI2 (LDH) and then to investigate the toxic impact of the two LDH on the adult freshwater snails (Biomphalaia alexandrina). Results showed that Co-Cd-Fe/PbI2 LDH has more toxic effect to adult Biomphalaria than Co-Cd-Fe LDHs (LC50 was 56.4 and 147.7 mg/L, 72 h of exposure, respectively). The effect of LC25 (117.1 mg/L) of Co-Cd-Fe LDHs exposure on the embryo showed suppression of embryonic development and induced embryo malformation. Also, it showed alterations in the tegmental architectures of the mantle-foot region of B. alexandrina snails as declared in scanning electron micrograph. Also, exposure to this sublethal concentration caused abnormalities in hemocyte shapes and upregulated IL-2 level in soft tissue. In addition, it decreased levels of nonenzymatic reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD), caspase-3 activity, and total protein content in significant manner. Glutathione S-transferase (GST) activity was not affected by LDH exposure. It caused histopathological damages in both glands of snails and also caused a genotoxic effect in their cells. The results from the present study indicated that LDH has risk assessment on aquatic B. alexandrina snails and that it can be used as a biological indicator of water pollution with LDH.

Evaluation of a Household Drinking Water Purification System Performance in terms of Organic – Inorganic Water Pollution Indicators and Ecological – Health Risk Assessment Indices

In this study, the performance of one of the most popular household drinking water purification systems (WPS) of Turkey was evaluated. Tap and purified water samples were taken from İpsala District (Thrace Region). A total of 23 significant water quality assessment parameters including essential and toxic metals (pH, TDS, EC, turbidity, Cl, NO3, SO4, PO4, BOD, COD, B, Al, Cr, Mn, Ni, Cu, Zn, As, Sr, Mo, Sb, Ba, Pb) were measured in water samples and how much the WPS improves these parameters were determined. Also Water Quality Index (WQI), Heavy Metal Pollution Index (HPI), Heavy Metal Evaluation Index (HEI), Nutrient Pollution Index (NPI), Cancer Risk (CR), Hazard Quotient (HQ) and Hazard Index (HI) were applied to data in order to assess the qualities of tap and purified water in terms of multiple effects of toxicants and possible risks of human health. As a result of this research, it was determined that the investigated WPS significantly improved the drinking water quality and significantly reduced the scores of applied ecological and health risk assessment indicators.

Study of water quality using of Physico-chemical parameters of two perennial ponds of Darbhanga district, Bihar

Darbhanga district is known as city of ponds. The present investigation was undertaken the study of the physico-chemical conditions of two perennial ponds- Maharani Pokhar and Raj Pokhar of Darbhanga city. Present study revealed that physico-chemical parameters was comparatively higher of Maharani Pokhar to other pond, Raj Pokhar. The water samples were analyzed for water temperature, transparency, pH, free CO2, chloride, carbonate, bicarbonate, magnesium, dissolved oxygen (DO) and biological oxygen demand (BOD). Higher value of physico-chemical parameters BOD, is considered to be sewage water pollution indicator for eutrophication and it also lower down the fish production.

Pollution of mine and ground water in Shakhtinsky district of Eastern Donbass

The main purpose of this research is to assess the role of coal mines in generation of chemical composition of mine and ground water in the oldest coal-bearing Shakhtinsky district in Eastern Donbass. The standard methods of mathematical and statistical data analysis are used to characterize mine and ground water (estimated arithmetical mean, median estimator, minimum and maximum values, standard deviation). The main index of water contamination is the contamination rate of water, soil, bottom sediments, etc., which is commonly used in geochemistry and geoecology, namely, the pollution load factor and the overall water pollution index. The water quality assessment uses the standards adopted in RF, USA, EU and WHO for drinking and fishery water. The practices of coal mining and mine closure widely use leaching, oxidation and dissolution elements, especially sulphur and sulphides, the content of which in coals and rocks reaches 4-5 %. As a result, mine water becomes highly mineralized and often acidic, and has the highest concentrations of Fe and Mn, hundreds of time higher than MAC in drinking water. Furthermore, it should be noted that MAC is largely exceeded by concentrations of Be, Ni, SO4, Mg and Na. Heavily contaminated ground water in coal-bearing Shakhtinsky district sometimes contain acid water with mineralization up to 15 g/l. The studies show that mine water is the main source of ground water pollution. The high contamination rate of mine and ground water in Shakhtinsky coal mining district necessitates monitoring observations toward improvement of water treatment technologies and environmental reclamation. In the development of mine water treatment technologies, it is necessary, first, to reduce the concentrations of Fe and Mn, as well as Be, Ni, SO4, Mg, and the index of mineralization M.
