However, research on the effects of drinking bottled low mineral water on bone health is sparse. OBJECTIVE To elucidate the skeletal effects of multi-generati...
Nineteen bottled water products were purchased from stores in Potsdam and Wappingers Falls, New York and analyzed for 71 inorganic elements by inductively coupled plasma - mass spectrometry (ICP-MS). The wide range in elemental concentrations observed suggests considerable variation in source water composition, processing, and treatment. Comparison with samples from a typical small municipal wa...
A cross-sectional telephone survey (n = 2,332) was performed to better understand the drinking water consumption patterns among residents in Waterloo Region, Ontario, Canada. We investigated the daily volume of water consumed (including tap and bottled) and factors related to that consumption. In addition, we investigated the daily volume of cold tap water consumed by those respondents who cons...

We find a water quality violation ...

Drinking water, tap and bottled, is essential for the proper functioning of the human body. It is also the main component of food and hence it should be safe for human health and free of contaminants...
Purpose: To assess whether bisphenol A contamination occurred in seven brands of bottled drinking water in Riyadh, Saudi Arabia. Methods: Liquid-liquid extraction (using dichloromethane) was used to analytically extract bisphenol A from drinking water bottles and a gas chromatograph-mass spectrometer was employed for its detection using a splitless capillary column and helium as the carrier gas...

This type of water supply is an appropriate alternative in prevention of much investment in full- scaled water treatment and duall water distribution system. In Iran, where water is considered as a serious challenge, use of bottled water can be con...
