Bioavailability of Metals from Drinking Water

Price: £50  

Bioavailability is an issue of concern for the UK Water Industry because it has important implications for the setting of drinking water quality standards and for assessment of potential risks to consumers in case of a contamination incident. This report discusses the concepts and issues concerning bioavailability of metals from different sources of exposure, relates them to the water industry and assesses the state of current knowledge. The report concludes that the current database regarding bioavailability of metals from diet is diverse but not very cohesive, rarely distinguishing between water and food components of the diet. The review did not find universal support for the traditionally held dogma that metals are more available for absorption from water owing to their presence in soluble form. Some metals e. g. iron, are preferentially absorbed from food owing to specifically developed uptake mechanisms to absorb forms primarily found in food. The forms found in drinking water, although soluble, may b
