Nine bottled water brands collected from retail shops and food shops beside the University of Dhaka were analyzed for their major and trace element constituents to ascertain their suitability for human consumption. The results obtained were compared with parametric values (PVs) set by European Community Council Directive 98/83/EC and the guideline values (GVs) recommended by WHO. It was found that the majority of the brands tested were low in mineral contents. Moreover, lower values of hardness, TDS and conductivity than the prescribed limits of WHO showed that water was deficient in essential minerals. Minerals like magnesium, potassium, calcium were present in some cases in such a low concentration that water seemed to be as good as distilled water. In case of heavy metals, only lead and cadmium were found to be below the detection limit (0.001 mg/L) which indicates bottled water brands are better for drinking.

Dietary Requirements

This study assesses the quality of drinking water from commercially available bottled waters in Bangladesh in terms of nutrient minerals and estimates their contribution in fulfilling the dietary requirements from such minerals. Ca, Mg, Na, trace element concentration and other physical parameters of the various bottled waters were investigated and compared on 13 samples of major local and imported brands of bottled water collected from local markets. It was found that imported brands had significantly high levels of bicarbonates (245 to 485 mg/l) compared to local brands (12.27 to 86.87 mg/l). Imported brands also had distinctively high levels of calcium (average concentration108.56 mg/l) and magnesium (average concentration 18.49 mg/L) concentrations compared to local brands and can fulfil upto 19.8% and 16.6% of the calcium and magnesium dietary reference intake (DRI) requirement respectively (for an average male). The DRI fulfilment from local brands hardly exceeded 3.3% for calcium and 7.3% for magnesium. The lack of mineral in local brands can be attributed to inadequate mineral amendments after extensive demineralization treatment. This study suggests that most of the local brands of bottled water in the market,poor in mineral content, may have negative dietary implications for long term consumption.Bangladesh J. Sci. Ind.

Bottled Mineral Water

A bottled spring water with a low mineral content was compared with tap water in the reconstitution and/or dilution of five different infant formulas and cows' milk. The osmolality, buffering power and renal solute load potential of the formulas reconstituted with the bottled water were all significantly lower than when tap water was used ( P < 0.01). When the bottled water was used to dilute cows' milk, the morphology of milk casein precipitates (after addition of rennet) was finer and more dispersed than when tap water was used. For formula reconstitution and milk dilution, a benefit, in terms of solute/electrolyte balance, appears to be conferred on infants by the improved rheological characteristics of modified milks reconstituted or diluted with this bottled mineral water.

Abstract The occurrence of fungi in drinking water systems has received increased attention over recent decades and fungi are now generally accepted as drinking water system contaminants. However, fungal contamination of bottled water has received little attention. Forty unopened bottled water samples, of different trademarks, were collected from various localities in Jeddah city, Saudi Arabia and analyzed for fungal contamination: (1) immediately after opening the bottles; and (2) after closing and storing them for 180 and 365 days. The fungal species were identified under a compound microscope followed by molecular sequencing. At least one fungal species were found in 58% of the bottles. In total, 18 fungal species belonging to 11 fungal genera were identified. Rhizopus nigricans and seven different species of Aspergillus were found to frequently contaminate the bottled water samples. Penicillium sp. were found in one sample. The 180 days storage of opened and reclosed bottles did not substantially affect the abundance of fungi or the species found. Some of the fungi identified may be pathogenic and the contamination of fungi in bottled water should be considered during the processing of water.
