Studies have shown perchlorate accumulates in some food crop leaves, tobacco plants and in broad-leaf plants (ATSDR 2008).
Newman, Johns Hopkins Medicine, using NASA and public domain images. Perchlorate seems to be everywhere these days. Perchlorate is used in munitions, fireworks, explosives, airbag initiators for vehicles, matches, signal flares, fertilizers, chlorine cleaners, and pool chlorination chemicals. A solid propellant consists of several chemical ingredients such as oxidizer, fuel, binder, plasticizer, curing agent, stabilizer, and cross-linking agent. Perchlorate, the explosive component of solid rocket and missile fuel, can affect the thyroid gland's ability to make essential hormones. It can serve as the only fuel in the propellant, the main fuel with smaller amounts of other fuel, or another substance may be the main fuel with the binder being a lesser contributor. Because perchlorate dissolves easily and is mobile in water, it is frequently detected in water supplies near sites where rocket fuel is used or made.
Photo: Perchlorate, a chemical compound used in rocket fuels (such as the Space Shuttle’s solid propellant seen here during the program’s final launch in 2011) and other materials, may be a more hazardous pollutant than previously thought. Perchlorate is a manufactured chemical and colorless salt that is most commonly used in rocket fuel. Perchlorate, the explosive main ingredient of rocket and missile fuel, contaminates drinking water supplies, groundwater or soil in hundreds of locations in at least 43 states, according to Environmental Working Group’s updated analysis of government data.
The specific chemical composition depends on the desired combustion characteristics for a particular mission. EPA Moves to Set Limit for Rocket Fuel Chemical in Water at Rate Scientists Say Is Unsafe The Trump administration proposed a drinking water standard of 56 parts-per-billion for perchlorate. Propellants in onboard rocket are burned in a controlled way (deflagration) to produce the desired thrust. Technical Fact Sheet – Perchlorate As of October … For fetuses, infants and children, disruptions in thyroid hormone levels can cause lowered IQ, mental retardation, loss of hearing and speech, and motor skill deficits. That is … The lowest cost solid fuel is based on nitrocellulose. There are high levels of perchlorate naturally in some areas such as the southwestern United States. ammonium perchlorate as rocket fuel Ammonium perchlorate composite propellant is used as rocket fuel in solid-propellant rockets . Surveys conducted by the U.S. Food and Drug Administration have detected perchlorate in food crops and milk (Murray and others 2008). Solid propellants are …

An ammonium perchlorate composite propellant (APCP) first-stage motor has a vacuum exhaust speed of 2.8 km/sec (Titan IVB SRMU).
During the developmental years, some propellants such as those using synthetic rubbers were cast at elevated temperatures where they were liquid and then became solid when they cooled. It is in a lot of water supplies, in fruits and vegetables, in Chile's Atacama Desert, and even on Mars.

Some chewing tobacco products contain perchlorates. Credit: M.E. In addition to the solid rocket motor, the booster contains the structural, thrust vector control, separation, recovery, and electrical and instrumentation subsystems.
