A fairly unique combination of chemical and physical properties of perchlorate poses challenges to its analysis and reduction in the environment or in drinking water. The implications of these properties are discussed in terms of remediative or treatment strategies. Recent developments are also covered.
The authors conclude that with proper manufacture, storage conditions, and handling, formation of perchlorate, chlorate, and bromate can be minimized. If care is not taken during manufacture and storage of hypochlorite solutions, however, perchlorate, chlorate, and bromate levels can exceed health-based guidelines in drinking water.

Furthermore, study data from human volunteers who were given perchlorate (at dosages up to 0.5 mg/kg/day for two weeks), and perchlorate-manufacturing workers, revealed no apparent change in various parameters of thyroid function despite exposure to the equivalent of anywhere from 200 to 17,500 ppb of perchlorate in water. 6,7 The …
Interest in perchlorate as environmental pollutant has increased since 1997, when high concentrations have been found in the waters of the Colorado River, USA. Perchlorate is very persistent in nature and it is slowly degraded. Although harmful effects of large doses of perchlorate on thyroid function have been proven, the environmental effects are still …

At room temperature, Aluminum Perchlorate typically exists as a white crystalline solid. It is odorless and its density is approximately 2.42 g/cm 3. The compound is soluble in water, alcohol, and acetone. The solubility in water and its high hygroscopic nature makes it an effective dessicant. Chemical formula: Al (ClO 4) 3.

In pharmacological doses, perchlorate decreases the active transport of iodine into the thyroid. During the 1950s, perchlorate (in high doses of 600–1000 mg daily) was used to treat hyperthyroidism. 1, 2 Its use diminished after several cases of aplastic anaemia were observed, perhaps due to the large doses employed. 3.
