Full Description

Scotland, with its soft, acidic waters and old, lead-plumbed dwellings, is acknowledged to have a serious problem with plumbosolvency (dissolved lead). Recent medical studies have confirmed that unacceptably elevated concentrations of lead in blood correlate with excessive levels of lead in drinking water. Bottle-fed infants were shown to be particularly at risk. Controlled water treatment that reduced lead solubility by pH adjustment and orthophosphate addition was found to be an effective method of reducing concentrations of lead in both water and blood. Duplicate-diet studies were undertaken also. Includes 34 references, figures.
