32 INORGANIC CONTAMINANTS OF HEALTH CONCERN 33 TABLE 2–1. 038 Source: Reference 2. Health Effects Aluminum has low acute toxicity. At lower doses, aluminum ad- ministered to laboratory animals is a neurotoxin. Chronic exposure data are limited, but indicate that aluminum likely affects phosphorus absorption in a way that can create weakness, bone pain, and anorexia. 3 After considerable controversy and extensive research, it appears that aluminum in drinking water does not significantly increase the incidence of Alzheimer’s disease.
Also, constituents such as lead and copper may be contributed from corrosion of piping and plumbing materials in the distribution system. The following sections present information on the source, occurrence, and health effects of 23 inorganic contaminants of concern. 1 per- cent—and the third most abundant element. It is found in nature as alumino silicates, such as clay, kaolin, mica, and feldspar. Bauxite, an impure hydrated oxide ore, is a major source of industrial production. Occurrence Aluminum occurs naturally in nearly all foods.
Water quality standards for these contaminants is found in Chapter 1. INORGANIC CONTAMINANTS OF HEALTH CONCERN Drinking water supplies are susceptible to contamination by a wide range of inorganic constituents that are known or suspected to cause adverse health effects. These contaminants enter water supplies from natural sources or from pollutant sources.
