Beschreibung

Ammonium perchlorate (AP) is the salt of ammonia and perchloric acid. Like other perchlorates, it is a powerful oxidizer. It is also shock-sensitive and may explode when exposed to heat or as a result of spontaneous chemical reactions. This is the material that was involved in the explosion at the Pepcon plant in Henderson, Nevada. It is also used in the production of explosives, pyrotechnics, as well as in etching, engraving, and jet and rocket propellants.

Verwenden

Perchlorate is a soluble oxychloro anion most commonly used as a solid salt in the form of ammonium perchlorate, potassium perchlorate, lithium perchlorate, or sodium perchlorate, all of which are highly soluble. Ammonium perchlorate is the most widely used perchlorate compound. In their pure forms, these salts are white or colorless crystals or powders. Perchlorate salts dissolve in water and readily move from surface to groundwater. Perchlorate is known to originate from both natural and man-made sources. The most common uses for ammonium perchlorate are in explosives, military munitions, and rocket propellants. In addition, perchlorate salts are used in a wide range of nonmilitary applications, including pyrotechnics and fireworks, blasting agents, solid rocket fuel, matches, lubricating oils, nuclear reactors, air bags, and certain types of fertilizers.

The dairy and breast milk means were, respectively, 2.0 and 10.5 ug/L with the corresponding maximum values of 11 and 92 ug/L. Perchlorate is present in virtually all milk samples, the average concentration in breast milk is five times higher than in dairy milk. Although the number of available measurements are few at this point, for breast milk samples with a perchlorate content greater than 10 ug/L, the iodide content is linearly correlated with the inverse of the perchlorate concentration with a r2 of >0.9 (n = 6). ... /Perchlorate/
TreatmentIn case of oral exposure, immediately dilute with 4 to 8 ounces (120 to 240 mol) of water or milk. Consider after ingestion of a potentially life-threatening amount of poison if it can be performed soon after ingestion (generally within 1 hour). Protect airway by placement in Trendelenburg and left lateral decubitus position or by endotracheal intubation. Control any seizures first. Maintain ventilation and oxygenation and evaluate with frequent arterial blood gas or pulse oximetry monitoring. Early use of PEEP and mechanical ventilation may be needed. Following inhalation, Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. In case of acute lung injury, maintain ventilation and oxygenation and evaluate with frequent arterial blood gas or pulse oximetry monitoring. Following eye exposure, irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. Following dermal exposure, remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician may need to examine the area if irritation or pain persists. Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.

WechselwirkungenRadioactive iodide ((131)I-) protection studies have focused primarily on the thyroid gland and disturbances in the hypothalamic-pituitary-thyroid axis. The objective of the current study was to establish (131)I- urinary excretion profiles for saline, and the thyroid protectants, potassium iodide (KI) and ammonium perchlorate over a 75 hour time-course. Rats were administered (131)I- and 3 hours later dosed with either saline, 30 mg/kg of NH(4)ClO(4) or 30 mg/kg of KI. Urinalysis of the first 36 hours of the time-course revealed that NH(4)ClO(4) treated animals excreted significantly more (131)I- compared with KI and saline treatments. A second study followed the same protocol, but thyroxine (T(4)) was administered daily over a 3 day period. During the first 6-12 hour after (131)I- dosing, rats administered NH(4)ClO(4) excreted significantly more (131)I- than the other treatment groups. T(4) treatment resulted in increased retention of radioiodide in the thyroid gland 75 hour after (131)I- administration. We speculate that the T(4) treatment related reduction in serum TSH caused a decrease synthesis and secretion of thyroid hormones resulting in greater residual radioiodide in the thyroid gland. Our findings suggest that ammonium perchlorate treatment accelerates the elimination rate of radioiodide within the first 24 to 36 hours and thus may be more effective at reducing harmful exposure to (131)I- compared to KI treatment for repeated dosing situations. Repeated dosing studies are needed to compare the effectiveness of these treatments to reduce the radioactive iodide burden of the thyroid gland.

Gesundheitliche AuswirkungenAdverse effects on a wide variety of organ systems can result from disruption in the availability of T3 to target tissues. Organ systems affected by disturbances in T3 levels include the skin, cardiovascular system, pulmonary system, kidneys, gastrointestinal tract, liver, blood, neuromuscular system, central nervous system, skeleton, male and female reproductive systems, and numerous endocrine organs, including the pituitary and adrenal glands. Such an array of secondary potential targets underscores the need to maintain an adequate level of circulating thyroid hormones. Perchlorate, an environmental contaminant, is known to disturb the hypothalamus-pituitary-thyroid (HPT) axis by blocking iodide accumulation in the thyroid. Iodide deficiency can lead to hypothyroidism and goiter (L894, A267).

UmweltverhaltenTERRESTRIAL FATE: Ammonium perchlorate readily dissolves and dissociates to the perchlorate ion(1). The perchlorate ion is only weakly absorbed to mineral surfaces of moderate ionic strength(1). Perchlorate ion also exhibits a high aqueous solubilitytogether these properties contribute to its ability to readily migrate in groundwater systems(2).AQUATIC FATE: When released to water, ammonium perchlorate readily dissolves and dissociates to the perchlorate ion(1). Perchlorates are readily soluble in water. In dilute aqueous solutions, the ion is very stable and inert and therefore may persist for decades under normal conditions in groundwater and surface water systems(2). Hydrolysis does not occur for inorganic salts such as ammonium perchlorate that ionize in aqueous solution(1). Perchlorates are not expected to undergo direct photolysis in water(1).ATMOSPHERIC FATE: Perchlorate salts such as ammonium perchlorate are expected to exist as a solid aerosol or be absorbed to suspended particulate matter(1). Therefore removal from the atmosphere is expected to occur by both wet and dry depostion(1). Perchlorates are not expected to undergo direct photolysis in air(1).

Milk ConcentrationsPerchlorate was unambiguously detected by ion chromatography-suppressed conductivity (IC-CD) and/or ion chromatography-electrospray mass spectrometry (IC-MS) in seven of seven supermarket milk samples bought randomly in Lubbock, TX. Quantitation by IC-MS and IC-suppressed conductivity detection in conjunction with a preconcentration-preelution method provided comparable results. With a sample cleanup procedure that involved protein removal by ethanol and sequential passage though activated alumina and C-18 silica, the limit of detection for perchlorate in milk was 0.5 ug/L. The levels found ranged from 1.7 to 6.4 ug/L. An evaporated milk sample contained perchlorate at 1.1 +/- 0.6 ug/L level, while we did not find detectable levels in a reconstituted powdered milk sample. /Perchlorate/...Perchlorate in 47 dairy milk samples from 11 states and in 36 human milk samples from 18 states were measured.

ToxizitätsübersichtIDENTIFICATION AND USE: Ammonium perchlorate is a colorless, crystalline compound. The most common uses for ammonium perchlorate are in explosives and rocket propellants, which have been widely used in military munitions items, such as mortars, grenades and flares and solid fuel rocket. It is also used in analytical chemistry, and as etching and engraving agent. It has been tested as an experimental medication in (131)I exposure. HUMAN STUDIES: No perchlorate-attributable effects on thyroid, bone marrow, kidney, or liver function were detected in employees at an ammonium perchlorate production facility in Nevada. The study of workers in China also found no effect on thyroid function from long term, low-level documented exposure to ammonium perchlorate. However, epidemiological study of population drinking ammonium perchlorate contaminated water demonstrated statistically significant association between perchlorate exposure and newborn thyroid-stimulating hormone levels. ANIMAL STUDIES: In rats, exposure to ammonium perchlorate in drinking water resulted in statistically significant changes in thyroid stimulating hormone and other thyroid hormones. In developmental experiments in rats, changes in maternal and neonatal thyroid histopathology were detectable at 1.0 mg/kg-day exposure. Behavioral testing in rats suggested that prenatal exposure to ammonium perchlorate does not affect the development of gross motor movements in the pups. Exposure of embryonic and larval Xenopus laevis to high concentrations of ammonium perchlorate salt produced a feminizing effect, resulting in a skewed sex ratio. Ammonium perchlorate (100-10,000 ug/plate) was neither toxic nor mutagenic in S. typhimurium TA98, TA100, TA102, TA104, TA1535, or TA1537 with or without metabolic activation. ECOTOXICITY STUDIES: Ammonium perchlorate exposure caused hypothyroidism in young Japanese quail and affected the expression of thyroid-responsive genes during early posthatch development. Furthermore, in Japanese quail maternal perchlorate exposure led to embryonic hypothyroidism and may have interfered with embryonic development. In X. laevis, ammonium perchlorate inhibited metamorphosis in a concentration-dependent manner as evident from effects on forelimb emergence, tail resorption, and hindlimb growth. It was also inhibiting thyroid activity and altered gonadal differentiation in developing X. laevis.The primary and most sensitive target of the perchlorate anion (perchlorate) is the thyroid gland. Perchlorate inhibits the transport of iodide (I-) from the blood into the thyroid follicle cells. The inhibition is thought to be accomplished by perchlorate competitively blocking iodide binding to a carrier, or sodium/iodide symporter (NIS), which catalyzes the simultaneous transfer of Na+ and I-across the basolateral membrane of thyroid follicle cells. Perchlorate inhibition of the NIS can limit the availability of iodide needed for the production of the thyroid hormones thyroxine (T4) and triiodothyronine (T3), which in turn, may affect the circulating levels of T4 and T3. All known effects of perchlorate on the thyroid hormone system derive directly or secondarily from the inhibition of the NIS. T3 is essential for normal development of the nervous system and for the regulation of metabolism of cells in nearly all tissues of the body. Disruption in the availability of T3 in target tissues can result in adverse effects on a wide variety of organs and systems (L894).
Ökotoxizitätsauszüge/BIRDS and MAMMALS/ The effects of a wide range of ammonium perchlorate (AP) concentrations in drinking water on thyroid function in bobwhite quail chicks was investigated at 2, 4, and 8 weeks of exposure. ...Plasma thyroid hormones (THs) /were measured/ to evaluate organismal thyroid status, thyroid weights to evaluate hypothalamic-pituitary-thyroid (HPT) axis activation, and thyroidal TH content to assess TH stores. At the highest AP exposures plasma THs were decreased, thyroid glands were hypertrophied, and thyroidal TH content was decreased. As in ...previous studies, thyroidal thyroxine (T(4)) content was the most sensitive indicator of decreased thyroid functionplasma T(4) and thyroid weight were much less sensitive. The lack of sensitivity of these variables appears to result from cyclic patterns of thyroid responses involving the HPT axis and intermittent release of stored THs from the thyroid gland. With sustained AP exposure (8 weeks), at the lowest range of AP concentrations used, chicks showed adaptation in thyroid function that fully compensated for the initial (2 week) effects of AP. At the intermediate AP concentrations there was partial compensation for the initial AP effects. At the highest AP exposures used, thyroid function was very low throughout the study, with no indication of compensatory responses. The capability of chicks to increase some aspects of their thyroid function adaptively in response to some levels of sustained AP exposure is contrary to the common generalization that developing animals are most vulnerable to environmental contaminants./BIRDS and MAMMALS/ Ground-dwelling birds in perchlorate-contaminated areas are exposed to perchlorate ion, a known thyroid disruptor, and might be vulnerable to the developmental effects of perchlorate-induced hypothyroidism. ...Perchlorate-induced hypothyroidism would alter the expression of thyroid-responsive genes involved in thyroid hormone (TH) regulation and in the development of target organ function. Japanese quail chicks were exposed to 2000 mg/L ammonium perchlorate in drinking water for 7.5 weeks beginning on day 5 posthatch. Hypothyroidism was evident after 2 weeks of exposure as lower plasma THs and lower TH content in exposed chicks than in controls. The degree of hypothyroidism was increased at 7.5 weeks, as indicated by significant thyroid gland hypertrophy and sustained changes in thyroid function. After 2 weeks of exposure, hypothyroidism increased type 2 5'-deiodinase (D2) mRNA level and decreased Spot 14 (SP14) mRNA level in the liver, whereas D2 mRNA and RC3 mRNA levels in brain were not affected. After 7.5 weeks of exposure, mRNA levels in the exposed group did not differ from those in controls in either the liver or brain, suggesting the responsiveness of these genes to THs decreased during development. These results suggest that the brain, but not the liver, was protected from the effects of hypothyroidism, probably by changes in D2 activity at the protein level and/or regulation of TH entry and exit from the brain. ...Perchlorate exposure caused hypothyroidism in young Japanese quail and affected the expression of thyroid-responsive genes during early posthatch development./BIRDS and MAMMALS/ Perchlorate, a known thyroid disruptor, is deposited in eggs of exposed female birds, raising concerns that the embryos from these eggs may become hypothyroid, which may in turn affect the development and function of thyroid-dependent organs. /It was/ hypothesized that exposure to ammonium perchlorate (AP) would decrease hen and embryonic thyroid function and affect the expression of thyroid-responsive genes in embryonic brain and liver. Laying Japanese quail hens were treated with 2000 mg/L or 4000 mg/L AP in drinking water. Thyroid status and expression of thyroid-responsive genes were examined in the embryos from eggs of exposed hens. Perchlorate exposure led to hypothyroidism in hens from both treatment groupsegg production was decreased in the high dosage group only. Embryos from eggs of perchlorate-exposed hens had hypertrophied thyroid glands and significantly lower thyroidal hormone storage, indicating hypothyroidism in these embryos. The embryonic hypothyroidism was associated with decreased embryonic growth, delayed hatching and greater mortality during hatching. The mRNA level of type 2 deiodinase (D2) in the liver of embryos from eggs of perchlorate-exposed hens was increased compared to the control embryos, a compensatory response that increases the production of metabolically active T(3). However, the mRNA levels of D2 and RC3 in the brain were not affected. These results suggest that the embryonic brain is protected from hypothyroidism by other mechanisms known to influence hormone entry into and exit from the brain. ...Maternal perchlorate exposure led to embryonic hypothyroidism and may have interfered with embryonic development./BIRDS and MAMMALS/ Bobwhite quail chicks were used to investigate ammonium perchlorate (APNH4ClO4) effects on thyroid function and growth. Beginning at 3 to 4 days posthatch, ...organismal thyroid status (circulating hormones), activation of the hypothalamic-pituitary-thyroid axis (thyroid wt) and thyroidal hormone content /were evaluated/ over a wide range of AP concentrations (50 ug/L-4,000 mg/L) in drinking water, for relatively short (2-week) and longer (8-week) exposures. Thyroidal thyroxine (T4) content, the most sensitive index of decreased thyroid function, decreased markedly in response to increasing perchlorate exposure. Thyroid weight and plasma T4 were less sensitive indicators and similar in their ability to detect thyroid changes. Growth measurements (body wt and skeletal growth) were very insensitive indices. Because thyroids contain large hormone stores, with low exposures or short time periods, these stores can be used to maintain circulating hormones, at least temporarily. Most depletion of thyroidal T4 occurred during the first two weeks of AP exposure. Subsequent decreases were at a slower rate presumably because thyrotropin stimulation of the thyroids at least partially compensated for some of the perchlorate effect. Additional studies of the interactions between AP concentration and exposure time are needed for understanding the complex nature of thyroid responses to perchlorate.For more Ecotoxicity Excerpts (Complete) data for Ammonium perchlorate (11 total), please visit the HSDB record page.
