Immediate precautionary measure

Immediate precautionary measure

Following oral exposure to antimony, administer charcoal as a slurry (240 mL water/30 g charcoal). Following inhalation exposure, 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 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. (T36)

Tumor necrosis factor-alpha (TNF-alpha) is a mediator of inflammation and has an important role in human and experimental renal diseases. Pentoxifylline (PTX) has been shown to inhibit cytokine synthesis, including TNF-alpha. The aim of the present study was to examine the effect of PTX on meglumine antimonate (Sb(V)) and antimony pentachloride (SbCl(5))-induced renal toxicity in rats. Sixty Wistar rats were divided into six groups according to the treatment employed over the period of 7 days: group I-saline (NaCl 0.9%); group II-PTX plus saline; group III-meglumine antimonate (Sb(V)) plus saline; group IV-meglumine antimonate (Sb(V)) plus PTX; group V-SbCl(5) plus saline; group VI-SbCl(5) with PTX. The animals' urinary concentration ability was evaluated before and after the end of the treatment. Urine and blood osmolality, sodium and creatinine concentration, and urine volume per minute (V) were determined. Creatinine clearance (CrCl), fractional sodium excretion (FE(Na)), and urine to plasma osmolality ratio (U/P osm) were calculated. TNF-alpha concentration in blood was assessed. On the seventh day, the animals were sacrificed and their kidneys were submitted to histological analysis. The meglumine antimonate (Sb(V))-treated animals showed an impaired renal capacity to concentrate urine, with low values of the ratio U/P osm, reduction in CrCl, and an increment in TNF-alpha serum levels. PTX associated with meglumine antimonate (Sb(V)) reduced TNF-alpha serum levels and was effective in preventing renal functional alterations. Rats treated with SbCl(5) showed functional and histopathologic alterations compatible with acute tubular necrosis, and treatment with PTX did not prevent SbCl(5)-induced nephrotoxicity. PTX was effective in preventing renal functional alterations induced by meglumine antimonate (Sb(V)) in rats.

Dermal exposure to antimony can cause antimony spots (papules and pustules around sweat and sebaceous glands). Antimony poisoning can also lead to pneumoconiosis. Alterations in pulmonary function and other effects including chronic bronchitis, chronic emphysema, inactive tuberculosis, pleural adhesions, and irritation can result from inhalation of antimony. Increased blood pressure can also result from antimony poisoning. Myocardial depression, vasodilation and fluid loss may cause shock with hypotension, electrolyte disturbances and acute renal failure. Cerebral oedema, coma, convulsions, and death are possible. (L741)

IDENTIFICATION AND USE: Antimony pentachloride is a colorless to yellow oily liquid. It is used as catalyst when replacing a fluorine substituent with chlorine in organic compounds. It is also used in analysis (testing for alkaloids and cesium), dyeing intermediates, as chlorine carrier in organic chlorinations. HUMAN STUDIES: Severe burns of cornea caused by exposure to high concentration of vapor. Inhalation causes coughing, choking, and variable symptoms of headache, dizziness, and weakness followed by pulmonary edema, difficult breathing, cyanosis, and bloody sputum. Skin contact causes severe burns. Burns heal slowly with scar formation. May produce anemia and bloody urine. Two deaths from antimony pentachloride poisoning have been reported. ANIMAL STUDIES: Antimony pentachloride is moderately toxic following acute oral exposure. Inhalation exposure of rats to 0.037 mg antimony pentachloride/L air, 2 hours/day for 4 months led to partly reversible damage to the lungs, heart, liver, kidneys and thyroid gland as well as accumulation of antimony in the spleen, heart, lymph nodes and thyroid gland. According to the available genotoxicity studies, antimony pentachloride was negative in the Salmonella/microsome test in strains TA 98 and TA 100 with and without metabolic activation, and did not increase the sister chromatid exchange rate in mammalian cells in vitro. Of three spot tests with antimony pentachloride in Bacillus subtilis, two were positive and one was negative.

The inhalation data suggest that the myocardium is a target of antimony toxicity. It is possible that antimony affects circulating glucose by interfering with enzymes of the glycogenolysis and gluconeogenesis pathways. The mechanism of action of antimony remains unclear. However, some studies suggest that antimony combines with sulfhydryl groups including those in several enzymes important for tissue respiration. The antidotal action of BAL depends on its ability to prevent or break the union between antimony and vital enzymes. Moreover, the The cause of death is believed to be essentially the same as that in acute arsenic poisoning. Antimony pentachloride reacts with water to form hydrochloric acid which has a direct corrosive effect on mucous membranes. (L793, T18, L741, A238)

Abdominal pain, vomiting, diarrhea can result from inhalation of antimony. Dyspnea, headache, vomiting,cough, conjunctivitis, and bloody purulent discharge from nose can result from inhalation exposure. Skin or eye contact can cause pain and redness of the exposed surface. (T64, L741)

/CASE REPORTS/ The effects of poisoning with diborane, hydrogen-sulfide (H2S), chlorine, phosgene, carbon-monoxide, or antimony-pentachloride were examined in 55 patients with pulmonary edema. Most of the cases of intoxication resulted from accidental acute exposure to gaseous agents in industrial settings. Chlorine gas in low concentrations induced damage to the mucosa of the nose and throat because of the solubility of the gas in water. Greater concentrations gave rise to severe pulmonary congestion and edema due to the hydrolysis of chlorine to hydrochloric-acid in the parenchymal lung tissue. Phosgene produced irritation of the conjunctiva, nasal, and pharyngeal membranes at low concentrations. At higher exposures, bronchial, bronchiolar, and alveolar inflammatory reactions ensued. At low exposures to H2S, damage occurred in the conjunctiva, cornea, and pharyngeal membranes. A more prolonged exposure to low concentrations evoked damage to the respiratory tract and produced pulmonary edema. Following high exposure to H2S, central nervous system depression developed with respiratory and olfactory paralysis. All patients with diborane intoxication survived; there were two deaths from H2S poisoning and two deaths from antimony-pentachloride poisoning. All patients received oxygen therapy (at 60 to 80 percent), usually with intermittent positive pressure breathing. The authors conclude that narcotic agents should not be administered to patients with respiratory depression. Victims of poisonings such as those described should be treated in intensive care units.

/LABORATORY ANIMALS: Acute Exposure/ Antimony-V-chloride is moderately toxic following acute oral exposure (LD50 rat oral 1115 mg/kg body weight). According to an unclear citation in the literature, the 2-hour LC50 in the rat is 720 mg/cu m.

/LABORATORY ANIMALS: Subchronic or Prechronic Exposure/ A limited subchronic study gave weak indications of partly reversible damage to the lungs, heart, liver, kidneys and thyroid gland as well as accumulation of antimony in the spleen, heart, lymph nodes and thyroid gland, following inhalation exposure of rats to 0.037 mg antimony-V-chloride/L air, 2 hours/day for 4 months.

/GENOTOXICITY/ The rec, Salmonella mutagenicity, and sister chromatid exchange (SCE) assays were conducted to evaluate the genotoxicity of three beryllium, three gallium, and four antimony compounds. Fifty milligrams samples of beryllium-chloride (BeCl2), beryllium-nitrate (Be(NO3)2), beryllium-oxide ((BeO), gallium-chloride (GaCl3), gallium-nitrate (Ga(NO3)3), gallium-oxide (GaO3), antimony-chloride (SbCl3), antimony-oxide (Sb2O3), antimony-pentachloride (SbCl5), and antimony-pentoxide (Sb2O5) were dissolved in distilled water and diluted serially two fold for the assays; both negative and positive controls were used. The rec assays involved spores of Bacillus-subtilis-M45 and Bacillus-subtilis-H17 and the SCE assays involved V79-Chinese-hamster cells. The Salmonella mutagenicity assays used the (TA100) and (TA98) strains and were conducted in the presence of rat liver-S9. In the rec assay, DNA damaging activity was exhibited by BeCl2, Be(NO3)2, GaCl3, Ga(NO3)3, SbCl3, SbCl5, and Sb2O3. None of the tested compounds were mutagenic to Salmonella and only SbCl3, Sb3O3, BeCl2, and Be(NO3)2 significantly induced sister chromatid exchanges. One of the antimony(III) compound, Sb2O3, was positive in both the rec and SCE assays at very low doses.

/GENOTOXICITY/ According to the available genotoxicity studies, antimony-V-chloride is negative in the Salmonella/microsome test in strains TA 98 and TA 100 with and without metabolic activation, and does not increase the sister chromatid exchange rate in mammalian cells in vitro. Of three spot tests with antimony-V-chloride in Bacillus subtilis, two were positive and one was negative. Overall, the genotoxic potential of the substance cannot be evaluated based on these studies.

These regulations apply to discharges of this substance. This designation includes any isomers and hydrates, as well as any solutions and mixtures containing this substance.

Toxic pollutant designated pursuant to section 307(a)(1) of the Federal Water Pollution Control Act and is subject to effluent limitations. /Antimony and compounds/

Antimony is widely distributed throughout the body. The hair and skin contain the highest levels of antimony. The adrenal glands, lung, large intestine, trachea, cerebellum, and kidneys also contain relatively high levels of antimony. Blood is the main vehicle for the transport of absorbed antimony to various tissue compartments of the body. Antimony is a metal and, therefore, does not undergo catabolism. Antimony can covalently interact with sulfhydryl groups and phosphate, as well as numerous reversible binding interactions with endogenous ligands (e.g., proteins). It is not known if these interactions are toxicologically significant. Antimony is excreted via the urine and feces. Some of the fecal antimony may represent unabsorbed antimony that is cleared from the lung via mucociliary action into the esophagus to the gastrointestinal tract. (L741)

Following intraperitoneal injection in the rat, 88% of pentavalent antimony is excreted in the urine and 1% in the feces. ...A limited subchronic study gave weak indications of partly reversible damage to the lungs, heart, liver, kidneys and thyroid gland as well as accumulation of antimony in the spleen, heart, lymph nodes and thyroid gland, following inhalation exposure of rats to 0.037 mg antimony-V-chloride/L air, 2 hours/day for 4 months.

Distribution in rats after chronic poisoning by inhalation of antimony pentachloride showed high antimony concn in blood. Levels in liver, kidneys, spleen and pancreas were similar.

Antimony can be trivalent or pentavalent in compounds. Both exist in antimony(IV) oxide, Sb2O4, and presumably in the deep violet haloantimonates (IV), such as Cs2(SbCl6). The pentavalent compounds, as well as most of the trivalent ones, are hydrolyzed by water to form antimony salts, e.g., SbOCl, and hydrated oxides. The only halides of antimony that have any industrial significance are the chlorides and fluorides. /Antimony compounds/
