| Interactions | Sodium and potassium chlorate were evaluated as promoters of renal tumors in N-ethyl-N-hydroxyethylnitrosamine (EHEN)-initiated F344 rats. Sodium chlorate and potassium chlorate were administered in the drinking-water for 28 weeks. There was an increased incidence of renal cell tumors (7/15 rats) in the EHEN-initiated group treated with sodium chlorate, but no effect was observed with potassium chlorate (1/5) relative to control rats (2/15). The small numbers of animals used in this study make the treatment groups indistinguishable from one another statistically ... .Sodium chlorate was tested in an initiation/promotion model of rat renal carcinogenisis. Two groups of 15 male Fischer 344 rats were given /1% sodium chlorate/ in drinking water, for the first two weeks during the intiation phase, N-ethyl-N-hydroxethylnitrosamine (EHEN) at 0.05% and, thereafter for 25 weeks sodium chlorate 1% or distilled water respectively. Two other groups, used as controls, were treated similarly, except that distilled water instead of EHEN was given in the initiation phase. There were no statistically significant differences in the renal cell tumors between sodium chlorate and distilled water-treated rats initiated with EHEN. The authors concluded that, under the conditions of this study, sodium chlorate showed no promoting effect in rat renal carcinogenisis. |

| Human Toxicity Excerpts | /HUMAN EXPOSURE STUDIES/ Administration of 500 mL of a 5 ppm solution to 10 males daily for 12 weeks did not cause any adverse clinical effects or changes in the biochemical or cellular composition of blood or urine./SIGNS AND SYMPTOMS/ Incident reports show that ingestion of toxic doses of sodium chlorate by humans produces gastritis, hemolysis, methemoglobinemia, hemoglobinurea, late toxic nephritis, and acute renal failure./SIGNS AND SYMPTOMS/ Poisoning symptoms after ingestion include nausea, vomiting, abdominal pain, diarrhea, cyanosis, dyspneamethemoglobinemia./SIGNS AND SYMPTOMS/ The irritant action on the gut causes nausea, vomiting, and abdominal pain. Once absorbed, hemoglobin is rapidly oxidized to methemoglobin, and intravascular hemolysis occurs. Cyanosis is prominent if methemoglobinemia is severe and may be the only presenting sign. Acute tubular necrosis and hemoglobinuria may result from the hemolysis or direct toxic injury. Plasma and urine are dark brown from the presence of free hemoglobin and methemoglobin. Release of potassium from red cell destruction results in hyperkalemia which may be severe enough to cause life-threatening arrythmias. The liver and spleen are often enlarged due to uptake of hemolyzed erythrocytes. Hypoxemia may lead to convulsions. Death may be the result of shock, tissue hypoxia, renal failure, hyperkalemia, or disseminated intravascular coagulation (DIC).For more Human Toxicity Excerpts (Complete) data for SODIUM CHLORATE (24 total), please visit the HSDB record page. |

In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern.

Applications & Uses
Description
Sodium chlorate (chemical formula: NAClO3) is an inorganic compound, appearing as white crystalline powder. It has an annual yield of several hundred million tons around the world. It has many applications. Its major commercial application is for the manufacture of chlorine dioxide which is used in bleaching of pulp. Sodium chlorate can also be used for the industrial manufacture of perchlorate compounds through electrolysis. It can also be used as a non-selective herbicide to control many kinds of plants such as morning glory, Canada thistle, Johnson grass and bamboo. In addition, it can also be used as a defoliant and desiccant. It is also used for the generation of chemical oxygen which is important for emergency oxygen generation in commercial aircraft. In industry, sodium chlorate is manufactured by the electrolysis of a hot sodium chloride solution. It is also useful for making inks, cosmetics, paper and leather.
Uses
Sodium chlorate is used to prepare chlorine dioxide in the pulp and paper industry. It is utilized for bleaching the wood pulp in order to make environmentally friendly and quality white paper products. It is also used to produce other perchlorate compounds in the industry.
General Description
Sodium chlorate in a water solution is a clear colorless liquid. Sodium chlorate is noncombustible but Sodium chlorate can accelerate the burning of surrounding combustible materials. This can easily occur if the material should dry out. Contact with strong sulfuric acid may cause fires or explosions.
