The article deals with the determination of the factors responsible for the degradation of the Reghaia nature reserve. The objective of this research was to evaluate the spatial variation of chemical pollutants including the accumulation of some heavy metals (Iron, Zinc, Copper, Cobalt, Cadmium, Silver, Nickel and Lead) in the water of Lake Reghaia, Algiers. The study was carried out on 64 water samples taken from Reghaia Lake. For physico-chemical parameters and for MTEs that have been assayed by atomic absorption spectrophotometry. On the chemical level, high levels of nitrates have been recorded in water between 4mg / l, 30mg / l and concerning the phosphate, it has a high content (5.7 mg / l). Surface waters have high levels of suspended solids. BOD5 and COD are high, with COD / DBO5 ratios well above 3, dissolved oxygen values do not comply with WHO standards with P = 0.000001. Water degradation is caused by the presence of latrines, piles of garbage, farms, draining of sanitation facilities in nature and especially in watercourses. Heavy metal pollution is significant and has been reported for Plomp (Pb), copper (Cu), iron (Fe) and cobalt (Co), which reached the high risk level (p <0.01) especially upstream of the Reghaia Lake. And that the MTE contents vary irregularly from one station to another and from one depth to another. The results reveal that the waters of the Réghaia Lake are of very poor quality and the degradation of the ecosystem is more and more increased, to this effect a treatment is recommended.

Abstract The occurrence of heavy metals (Cd, Cr, Cu, Ni, Pb, Zn) has been determined in the fluvial sediment samples collected along three transects in the Middle Odra River (western Poland) with a width of 360 m. The total concentrations of the metals were obtained after HNO3 microwave digestion and the available fractions of heavy metals were determined by single extraction procedures using two extractants: 0.01M CaCl2 and 0.05M EDTA. The measurement of physico-chemical parameters was also performed. The determination of total and available fractions of heavy metals, except potential available fractions of Cr, revealed high concentrations of studied elements detected in the sediment samples characterized by high content of coarse and very coarse-grained sand fraction and high content of organic matter. It was found that the concentrations of total and available fractions of metals could increase along with the content of organic matter, Eh values and concentrations of H+. Apart from the above, those concentrations become the lowest, the higher the content of medium grain size fractions is. Furthermore, the amounts of CaCl2 and EDTA extractable metals increase in the sediments samples characterized by the lowest total and available concentrations of heavy metals.

Assessment on the level of pollution of Turag river water was performed by measuring various physico-chemical parameters. Water samples were collected five times in a year both dry and rainy season at five different locations: Bishwa Ijtema field, Tongi Bridge, Kachare ghate, River side of Dhaka Dying and Effluent of Dhaka Dying. Most of the measured parameters exceeded the permissible limit of standard level. Values for different parameters at different points were recorded such as Temperature (T): 23.9 to 31.2°C, pH: 7.2 to 10.1, Salinity: 64 to 933 ppm, Total dissolved solid (TDS): 90 to 1244 ppm, Electrical Conductivity (EC): 135 to 1856 µs/cm, Dissolve oxygen (DO): 0.5 to 3.6 mg/L and Chemical oxygen demand (COD): 220 to 1170 mg/L. The concentration (ppm) of heavy metals were also observed such as Chromium (Cr) 0.0339 to 0.6334, Cadmium (Cd) 0.0068 to 0.0170, Nickel (Ni) 0.1282 to 0.6207, Cooper (Cu) 0.0148 to 0.1703 and Zink (Zn) 0.0366 to 0.1890 at dry season. The values of different parameters determined are above the safe limits recommended by DoE, EQS and WHO. Therefore, it can be concluded that water relieved from selected locations were not suitable for human consumption during the period of experiments.Bangladesh J. Sci. Ind. Res. 51(3), 193-202, 2016

This paper intends to prepare the environmental impact of "Ganesh Idol" & "DurgaPratima" immersion on water quality of Kakerpura Lake, Mhow. For this purpose site of Kakerpura lake was selected where idols are actually immersed. Water samples were collected in morning at different intervals i.e. pre-immersion (August) immersion (September, October) Post immersion period (November). The "Ganesh Idols" & "DurgaPratima" are made up of degradable and non-degradable components and paints containing heavy metals due to that immersion activity deteriorates water quality. The physico-chemical parameters were analysed to study the environmental impact of idol immersion on Kakerpura Lake and these parameters shows the significant variation due to immersion of idols.

The quality of water from surface and ground water sources in Hong Local Government Area of Adamawa State was studied to determine their suitability or otherwise for drinking and domestic purposes. Nine (9) samples, three (3) each from streams, dug wells and boreholes were randomly collected, during the dry season, in the months of October and November, 2016. The samples were analysed, and the values compared with WHO and NAFDAC standards to ascertain their compliance. The results of the analysis revealed that the physico-chemical parameters studied and concentrations of heavy metals determined, falls within the maximum permissible limits of WHO and NAFDAC standards for drinking water. However, the water samples were predominantly alkaline (pH 6.30 ± 0.10 to 7.00 ± 0.10), (6.70 ± 0.20 to 7.30 ± 0.20), and (7.60 ±0.20 to 8.20 ± 0.10), for boreholes, dug wells and streams respectively. The heavy metals concentrations were determined using Atomic Absorption Spectrophotometric method. The suitability of water for domestic and drinking purposes indicates that water samples were within the standards prescribed for potable waters.

Abstract. This study investigated ground water quality collected from two industrial and residential locations each of Lagos metropolis. Prescribed standard procedures of American Public Health Association (APHA) were used to measure physico-chemical parameters of each of the ground water samples which include pH, EC, DO, TDS, BOD, COD, anions (Cl−, NO3−, SO4−, PO4−) and heavy metals (Cu, Zn, Pb, Mn, Fe, Co, Cd and Cr). From laboratory analysis, measured physico-chemical parameters were within the permissible ranges specified by WHO and NSDWQ except pH, TDS, EC, Pb, Mn and Fe for ground water samples from industrial locations and pH, Pb, Mn and Fe for residential locations. Higher concentrations of TDS and EC reported for ground water samples from industrial locations were attributed to heavy discharge of effluents from industrial treatment plants as well as dissolution of ionic heavy metals from industrial activities of heavy machines. Statistical Pearson’s correlation revealed physico-chemical parameters to be moderately and strongly correlated with one another at either p ˂ 0.05 or ˂ 0.01. In conclusion, ground water samples from residential locations are more suitable for drinking than those from industrial locations.

Abstract The quality of well-dug water for drinking and irrigation purposes must be measured as part of a sustainable groundwater analysis. The study aimed to assess water quality and to evaluate their usefulness for drinking and irrigation, using the Drinking Water Quality Index (DWQI) and Irrigation Water Quality Index (IWQI). To achieve this, standard methods were used for the determination of physicochemical parameters of the water samples, while using models (ESP, SSP, SAR, MAR, KR, TDS, and EC) to ascertain their suitability for drinking and irrigation. According to the findings, the determined Physico-chemical parameters were compared to standard limits and found desirable because they were within the guidelines. Low pH (6.4-7), total dissolved solids (106–130 mg/L), total hardness (42–56 mg/L), calcium (3.5–8.3 mg/L), magnesium (1.13.6 mg/L), nitrate (4.6–16 mg/L), chloride (1.8–3.1), and sulphate (14–15. mg/L) in the well samples were found to be the key cause of the low DWQI and IWQI value at these sites. The results also depicted that all the water samples are of exceptional quality (excellent).

This paper shows the results obtained in field analysis performed at the Tamis River, starting from the settlement Jasa Tomic - border between Serbia and Romania to Pancevo - confluence of Tamis into the Danube. The Tamis is a 359 km long river rising in the southern Carpathian Mountains. It flows through the Banat region and flows into the Danube near Pancevo. During the years the water quality of the river has severely deteriorated and badly affected the environment and the river ecosystem. In situ measurements enabled determination of physico-chemical parameters of water quality of the Tamis River on every 400 m of the watercourse, such as: water temperature, pH value, electrical conductivity, contents of dissolved oxygen and oxygen saturation. The main reason of higher pollution of Tamis is seen in connection to DTD hydro system. Sampling was performed at 7 points with regard to color, turbidity, total hardness, alkalinity, concentration of ammonium nitrogen, nitrite nitrogen, nitrate nitrogen, iron, chlorides and sulphates in samples. The aim of the present work was to evaluate water quality in the Tamis River taking into account significant pollution, which originates from settlements, industry and agriculture, and to suggest appropriate preventive measures to further pollution decreasing of the river's water.
