Perchlorates have been found in food and milk. Some plants, especially leafy green vegetables. They are found in environment in two forms either solid or dissolved in water, Food, milk, leafy green vegetables.
Four perchlorates are of primary commercial interest: ammonium perchlorate (NH 4 ClO 4), perchloric acid (HClO 4), potassium perchlorate (KClO 4), and sodium perchlorate (NaClO 4). Perchlorate is the anion resulting from the dissociation of perchloric acid and its salts upon their dissolution in water. Except for potassium perchlorate, perchlorate salts are soluble in water and dissociate into the perchlorate anion and the cation from the salt. In the U.S., perchlorate has been found in the water resources of several western states, including Lake Mead and the Colorado River, ranging from 4 to16 μg/L. April 3, 2009 -- CDC scientists have found a chemical called perchlorate in samples of powdered infant formula. Perchlorate occurs naturally in the environment; it's also made for use in rocket propellant, explosives, fireworks, and road flares. Perchlorate has been found in drinking water in some areas of the country, as well as in food and breast milk. Purpose. This fact sheet answers questions about CDC’s recent study of perchlorate in infant formula published in The Journal of Exposure Science and Environmental Epidemiology1. It explains what the study looked at, what it found, and what CDC’s next steps will be. Previous CDC studies have shown that nearly everyone in the U.S. is exposed regularly to low levels of perchlorate. People are exposed through eating food, and drinking milk and water that contain perchlorate. Trace levels of perchlorate have been found in both breast milk and infant formula. Perchlorate has been linked to its negative influence on the thyroid gland. Most perchlorates are colorless solids that are soluble in water, except for potassium perchlorate, which has the lowest solubility of any alkali metal perchlorate (1.5 g in 100 mL of water at 25 °C). In the U.S., perchlorate has been found in the water resources of several western states, including Lake Mead and the Colorado River, ranging from 4 to16 μg/L. You may be exposed to perchlorates if you eat food or drink water that contains perchlorates. Perchlorates have been found in food and milk. Some plants, especially leafy green vegetables, have been found to have elevated levels of perchlorate. When water containing perchlorate is used to irrigate the plants, perchlorate is left behind when water evaporates from the leaves of the plants. Perchlorates are colorless and have no odor. Five perchlorates are manufactured in large amounts: magnesium perchlorate, potassium perchlorate, ammonium perchlorate, sodium perchlorate, and lithium perchlorate. Perchlorates are found in the environment in two forms, either as a solid or dissolved in water. Perchlorate exposure may occur in any of the following ways: 1  Drinking water that is contaminated with perchlorates. 2  Most contaminated water supplies are found near hazardous waste sites where perchlorates are found. 3  Eating food or drinking milk contaminated with perchlorates. Perchlorates can enter the environment in and around sites where rockets are made, tested, and taken apart. Perchlorates have also been found in milk and food. Factories that make or use perchlorates may also release them into soil and water. Perchlorates will not stay in soil and will wash away with rain water. Perchlorates do eventually end up in ground water This fact sheet answers the most frequently asked health questions (FAQs) about perchlorates. For more information, call the ATSDR Information Center at 1-800-232-4636. This fact sheet is one in a series of summaries about hazardous substances and their health effects. Perchlorates are colorless salts that have no odor. There are five perchlorate salts that are manufactured in large amounts: magnesium perchlorate, potassium perchlorate, ammonium perchlorate, sodium perchlorate, and lithium perchlorate. Perchlorate salts are solids that dissolve easily in water.
