background bottled mineral water is generally considered more pure than tap water in developing countries. immunocompromised patients and those with co morbid conditions are often offered bottled mineral water since they are believed to be safer. the present study was designed to determine the risk of common bacterial contamination of commercially available bottled mineral water in iran. materi...

UNLABELLED ISSUED ADDRESSED: The increase trend in the prevalence of dental caries in Australian children is a concern to public health professionals. Attitudes, behaviours and lifestyle patterns established in childhood are often carried throughout adult life. The objective of the study was to estimate the proportion of Perth metropolitan year two public primary school children drinking tap wa...

Less than 1 % of bacteria in drinking water are typically culturable on conventional growth media with the heterotrophic plate count (HPC) method. In addition, it is believed that some culturable bacteria can enter a state of unculturability when exposed to nutrient-poor environments. Therefore, a need exists for rapid and cultivation-free methods with which the viability/activity of drinking w...

A portable total reflection X-ray fluorescence spectrometer was applied to commercial bottled drinking water containing 62 ppb (microg/L) V, 7.5 ppm (mg/L) Ca, and 1 ppm K. A dry residue, prepared by repeated pipetting and drying a 20 microL portion of drinking water on a sample holder six times, and another dry residue, prepared by pipetting and drying a 120 microL portion of the drinking wate...

In this study the sensing capabilities of a combination of metals and conducting polymer electrodes for drinking water and dissolved tastants using an AC-impedance mode in frequency range 10 to 10 Hz at 0.1 V potential has been carried out. Classification of seven different bottled and municipal drinking water samples along with various tastants dissolved in DI water (DI water) for KCl (5mM) (s...

The occurrence of Campylobacter spp was examined in a variety of waters in Northern Ireland. Conventional cultural techniques were employed with 768 water specimens, including drinking waters (tap, spring, bore hole and bottled) and recreational waters (swimming pool, lough, river and sea). Positive waters included 1/11 (9.1%) drinking water from untreated well water, as well as 5/12 (41.7%) un...
