The VSEPR predicts a tetrahedral shape. A suppression technique, which suppresses the conductivity of the electrolyte but not the separated ions, can further improve sensitivity. The lung tissue was removed and analyzed, and it was found that perchlorate injected lung tissue showed several adverse effects when compared to the control group that had been intratracheally injected with saline. [68][needs update], In 2006, a study reported a statistical association between environmental levels of perchlorate and changes in thyroid hormones of women with low iodine. [75], In 1998, perchlorate was included in the EPA Contaminant Candidate List, primarily due to its detection in California drinking water. Studies have been performed on rabbits where perchlorate has been injected into the trachea. What is Perchlorate? Structural Formula. Perchlorate is a persistent contaminant of concern that has presented a number of issues to the government, the private sector and other organizations and interested parties. The VSEPR predicts a tetrahedral shape. Perchlorate is an anion having the chemical formula ClO 4–.

Perchlorate reduces hormone production in the thyroid gland. There are 32 valence electrons available for the Lewis structure for ClO 4-.. Be sure to check the formal charges to make sure that you have correct Lewis structure for ClO 4- VLA4NZX2P4. nov", "Detection of Perchlorate & the Soluble Chemistry of Martian Soil at the Phoenix Mars Lander Site", "Stability of perchlorate hydrates and their liquid solutions at the Phoenix landing site, Mars", Photooxidation of chloride to perchlorate in the presence of desert soils and titanium dioxide, Look What We Found on Mars - Curiosity Rover Serves Up Awesome Science, "Toxic Mars: Astronauts Must Deal with Perchlorate on the Red Planet", Mars covered in toxic chemicals that can wipe out living organisms, tests reveal, "NASA Confirms Evidence That Liquid Water Flows on Today's Mars", "NASA Says Signs of Liquid Water Flowing on Mars", "Video Highlight (02:58) - NASA News Conference - Evidence of Liquid Water on Today's Mars", "Video Complete (58:18) - NASA News Conference - Water Flowing on Present-Day Mars m", "A review of perchlorate occurrence in public drinking water systems", "Perchlorate, Source and Distribution in Groundwater at Massachusetts Military Reservation", "Inorganic Chemical Maximum Contaminant Levels, Monitoring Requirements and Analytical Methods", "Fireworks Displays Linked To Perchlorate Contamination In Lakes", "Perchlorate in the Pacific Southwest: California", Perchlorate found in breast milk across US, "Perchlorate levels in samples of sodium nitrate fertilizer derived from Chilean caliche", "Eliminating Water Contamination by Inorganic Disinfection Byproducts", "ARA Perchlorate Contamination Solutions", "The effect of perchlorate, thiocyanate, and nitrate on thyroid function in workers exposed to perchlorate long-term", "Health effect assessment for environmental perchlorate contamination: The dose response for inhibition of thyroidal radioiodide uptake in humans", "Urinary Perchlorate and Thyroid Hormone Levels in Adolescent and Adult Men and Women Living in the United States", "Perchlorate: Health and Environmental Impacts of Unregulated Exposure", "Perchlorate Levels in Pregnancy Linked to Low Childhood IQ", NAS Report: The Health Effects of Perchlorate Ingestion, Macho Moms: Perchlorate pollutant masculinizes fish: Science News Online, Aug. 12, 2006, New Scientist Space Blog: Phoenix discovery may be bad for Mars life, State Threatening To Sue Military Over Water Pollution, Health Effects Of Perchlorate From Spent Rocket, Dept of Defense, Dept of Energy, and US Environmental Protection Agency's Strategic Environmental Research and Development Program, Elimination of Perchlorate Oxidizers from Pyrotechnic Flare Compositions, 2009, https://en.wikipedia.org/w/index.php?title=Perchlorate&oldid=982902782, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Articles with unsourced statements from November 2017, All articles with vague or ambiguous time, Vague or ambiguous time from November 2017, All articles with specifically marked weasel-worded phrases, Articles with specifically marked weasel-worded phrases from November 2017, Wikipedia articles in need of updating from May 2017, All Wikipedia articles in need of updating, Articles with unsourced statements from May 2017, Articles lacking reliable references from November 2017, Creative Commons Attribution-ShareAlike License, The dominant use of perchlorates is as oxidizers in propellants for rockets, fireworks and highway flares. It originates from perchloric acid. The oxidation state of chorine atom in this compound is +7. [69] When the Blount research was re-analyzed with the creatinine adjustment made, the study population limited to women of reproductive age, and results not shown in the original analysis, any remaining association between the results and perchlorate intake disappeared. Perchlorate anion. EPA prepared extensive responses to submitted public comments. On February 11, 2011, EPA determined that perchlorate meets the Safe Drinking Water Act criteria for regulation as a contaminant. Structural Formula ClO 4- perchlorate ion. It originates from perchloric acid. Of particular value is, Potassium perchlorate has, in the past, been used therapeutically to treat, This page was last edited on 11 October 2020, at 02:10. Both DWEL and Cleanup Guidance were based on a 2005 review of the existing research by the National Academy of Sciences (NAS). Perchlorate is an anion having the chemical formula ClO 4 –. Synonyms. The majority of perchlorates are commercially produced salts. CopyCopied, VLTRZXGMWDSKGL-UHFFFAOYSA-M The agency then calculated a "drinking water equivalent level" of 24.5 ppb by assuming a person weighs 70 kg (150 lb) and consumes 2 L (0.44 imp gal; 0.53 US gal) of drinking water per day over a lifetime. UNII-VLA4NZX2P4. regarding perchlorate use. [O-]Cl(=O)(=O)=O ", EPA (2011-02-11). The perchlorate ion has the formula ClO4 and has a -1 charge. Adverse effects included inflammatory infiltrates, alveolar collapse, subpleural thickening, and lymphocyte proliferation. [72], Some studies suggest that perchlorate has pulmonary toxic effects as well. Potassium Perchlorate is the potassium salt of perchloric acid and a member of the Hofmeister ions series with thyroid blocking properties. Perchlorate(1-) ClO4. Molecular Formula ClO 4; Average mass 99.451 Da; Monoisotopic mass 98.949059 Da; ChemSpider ID 109953 [86] EPA Administrator Andrew R. Wheeler signed a proposed rule on May 23, 2019 and the proposal was published on June 26, 2019. EPA (1998-03-02). [80] California also issued guidance[when?] Perchlorate (ClO 4 –) is both naturally occurring and a man-made contaminant that is increasingly found in groundwater, surface water and soil.Most perchlorate manufactured in the U.S. is used as an oxidizer in solid fuel for rockets and missiles. tetraoxidochlorate(1-) Perchlorate (8CI,9CI) ClO4(-) DTXSID6024252. [74] Subsequent investigations have indicated the connection between administration of potassium perchlorate and development of aplastic anemia to be "equivocable at best", which means that the benefit of treatment, if it is the only known treatment, outweighs the risk, and it appeared a contaminant poisoned the 13. Molecular Formula. PERCHLORATE ION. Perchlorate Ion. All the bonds are the same length and must be thought of as a hybrid of multiple resonance structures. What is Perchlorate? FDA approved perchlorate use in food packaging in 2005. [76][3], In 2003, a federal district court in California found that the Comprehensive Environmental Response, Compensation and Liability Act applied, because perchlorate is ignitable, and therefore was a "characteristic" hazardous waste.
