A method capable of accurately and selectively measuring Cr3+ in water is required and was therefore studied. The precision and reproducibility of chlorophosphonazo I color reaction spectrophotometry (CCRS) for the selective determination of Cr3+ was improved to be acceptable standards. The CCRS established is therefore an accurate, reproducible and inexpensive method. It also has reasonably go...

A 2011 survey of Mexico City’s households revealed that families prefer alternative sources of drinking water instead of relying in the city’s quality supply services. These include the purchase of bottled water, installation of filtration devices, and other means of water purification. The demand for better water quality was tested by estimating the household’s willingness to pay (WTP), using ...

METHODS Dietary intake data for 845 children aged 4-13 years came from the nationally representative cross-sectional National Diet and Nutrition Survey, 2008-2011. Beverage categories we...

Storage of water that was deliberately contaminated with enteric viruses in polyethylene terephthalate (PET) bottles led to a rapid decrease of the apparent viral load, thereby hampering the development of samples for a collaborative evaluation of viral detection methods for bottled water. To determine if this decrease was due to spontaneous inactivation or to adhesion, an elution protocol was ...
