Perchlorate is chemical used in military and industrial products such as solid rocket fuels, explosives, fireworks, road flares and air bag inflation systems.

Perchlorate can affect Thyroid function. Perchlorate is chemical used in military and industrial products such as solid rocket fuels, explosives and fireworks, road flares and air bag inflation systems. It can also occur naturally at low levels in the environment, for example in certain arid regions of the world. Recent sampling has detected the presence of very low levels of perchlorate in some Canadian drinking water sources. American data also show that perchlorate could also be found in foods such as lettuce, milk and bottled water (Health Canada,

Exposure to significantly higher levels of perchlorate has the potential to cause some health effects, primarily related to thyroid function. Perchlorate inhibits the transfer of iodide from the blood to the thyroid gland, which is required for the gland to produce hormones essential for metabolism and growth. Although short-term fluctuations in thyroid hormones are not a concern to healthy adults, long-term disruptions may result in hypothyroidism and related changes in metabolism, decreased mental performance, and altered development. This is of particular concern for people who are already experiencing hypothyroidism, as well as for pregnant women and children (Health Canada,

In 2005, the American National Academy of Science produced a report on the health implications of perchlorate ingestion, which has been used by the U.S. Environmental Protection Agency to establish a preliminary clean-up goal of 24.5 ppb for perchlorate in water. There is currently no enforceable national drinking water standard for perchlorate either in Canada or in the United States, although various states have implemented guidelines or goals ranging from 1 ppb to 18 ppb for perchlorate in drinking water (Health Canada,
