Assessment of Zinc Intake From Enriched Water and Other Dietary Sources in Kisumu, Kenya

Device: LSF-filtering device LifeStraw Family is a water purification device that by means of hollow fibres removes solid particles (\<0.5 Nephelometric Turbidity units turbidity reduction), bacteria (\>Log 6 reduction), viruses (\>Log 4 reduction) and cysts (\>Log 3 reduction). Zinc enrichment is provided by a chamber housing a zinc releasing glass-plate that is placed annexed to the hollow fibre column. It is estimated that the LSF can provide about 5 mg of zinc/l of filtered water. By consuming daily a portion of 0.6 litres of enriched water, \>100% of the age-specific estimated physiologic requirement would be covered, assuming a fractional absorption of 40%.
