“…More than 70.15% of the samples (Table 6) Zinc is one of the important trace elements that play a vital role in the physiological and metabolic process of many organisms. Nevertheless, higher concentrations of zinc can be toxic to the organism (Rajkovic et al, 2008). It plays an important role in protein synthesis and is a metal which shows fairly low concentration in surface water due to its restricted mobility from the place of rock weathering or from the natural sources (Rajappa et al, 2010).…”

The study was undertaken to assess the status of drinking water quality in the urban areas of the Tigray region, northern Ethiopia. A total of 106 drinking water samples were collected from 16 densely populated urban areas of the region, viz.: Alamata, Korem, Maichew, Adigudom, AbyiAdi, Hagereselam, Zalambessa, Adigrat, Edagahamus, Firewoini, Wukro, Mekelle, Indaselassie, Axum, Adwa, and Enticho. All the samples were analyzed for six physicochemical parameters such as temperature, conductivity, total dissolved solids (TDS), salinity, pH, and turbidity and ten heavy metals,viz., As, Cd, Co, Cu, Cr, Fe, Mn, Ni, Pb, and Zn using standard procedures. The results were compared with other national and international standards. Among the analyzed samples, regarding physicochemical parameters, 84.01 % for electrical conductivity, 47.17 % for TDS and 31.13% for turbidity show concentrations higher than the WHO (2008) recommended values. More than 93.4% of the samples were within the United States Environmental Protection Agency (US EPA) admissible pH limit (6.5-8.5) and all the samples analyzed were within the EU (1998) admissible pH limit (6.5-9.5). All samples contain manganese and copper within the WHO (2008) maximum admissible limit, but arsenic (40.3 %), cadmium (7.46 %), chromium (64.18 %), iron (37.31 %), nickel (7 %), and lead (29.85 %) crossed the maximum admissible and desirable limits recommended by WHO (2008). The maximum admissible limit of cobalt in drinking water is not mentioned by WHO, but all the samples analyzed were found to comply the New Zealand (1000 μg/L) and US EPA (100 μg/L) maximum admissible limits. Although no guideline is set by WHO (2008) for Zinc level in drinking water, of the samples analyzed, 94.02% comply the New Zealand standard and 97.01% comply all the maximum admissible limits referred in the present study. In general, the results of the present study have shown that some of the physico-chemical parameters have shown values higher than the WHO (2008) recommended maximum admissible limits. This is an indication of pollution hazards and weak drinking water treatment practices in the areas, which in turn have important human health implications. This study, therefore, recommends the government and other responsible authorities to take appropriate corrective measures.

“…The reduction in the fluorescence intensity has been brought to the lowest degree possible by the technique of "standard addition" after the extraction of uranium by the synergetic mixture TOPO (three-n-octal phosphine oxide) ethyl acetate. The fluorescence intensity has been determined by means of the Fluorimeter 26-000 Jarrel Ash Division (Fisher Scientific Company, Waltham, 1978) [17][18][19][20][21][22].…”

In this paper it is presented the analysis of basic physical and chemical parameters, alkalinity and acidity, the analysis of kations, anions, heavy metals, microbiological analysis and determination of uranium content in waters of Serbia from 10 springs of Arandjelovac region and 2 samples of bottled drinking water. It is done by different methods of analysis according to which conclusion about the content and the quality of these waters can be made. The pH value of analysed waters shows that waters from springs Maiden spring, Je?ovac, Vrelo and Svin?ine are slightly acid, while mineral waters from springs Aleksijevi?, Exploitation and Talpara are slightly basic. The sample from Olga’s spring has slightly lower pH value. According to Regulation on the hygiene of drinking water, conductivity should be less than 1000 μS/cm. This condition is fulfilled by waters from springs Aleksijevi?, Talpara (ordinary), Maiden and Olga’s spring, Svin?ine and water from city supply system. Springs Je?ovac and Vrelo have slightly increased conductivity, while springs Exploitation and Talpara have conductivity significantly above the allowed values (mineral). Analysed natural mineral waters contain only hydrogencarbonates (bicarbonate). According to the content of bicarbonate it was concluded that samples from springs Exploitation, Talpara (mineral), Vrelo and Svin?ine belong to the category of bicarbonate waters, as the content of hydrogencarbonate in these samples is higher than 600 mg/dm3. Analysed mineral waters don’t show acidity towards methyl orange, which means that acidity of analysed waters comes from dissolved carbon acid

The study was undertaken to assess the status of water quality in the urban areas of Gharian district, northwestrn Libya. All the samples were analyzed for four physicochemical parameters such as total hardness, pH, nitrate and sulfate and twelve heavy metals, Al, Ba, Se, Hg, Cd, Cu, Cr, Fe, Mn, Ni, Pb, and Zn using standard procedures. The analysis indicated that concentrations of the metal were mostly far below the maximum allawable concentration. However, the concentration of Ni in some of the water samples were relatively high when compared to the Libyan and International standards values. Relatively high concentrations of Se had been detected in all samples. The results showed that other parameters differ form each sample. Total hardness, nitrate and sulfate concentration of all samples were higher than the International standards. The pH of all analyzed samples was within the allowable limit.
