化学的特性
Sodium chlorate, NaCI03, is colorless,odorless crystals with a cooling, saline taste, is soluble in water and alcohol,but must not be triturated with any combustible substance. Derived by heating and electrolyzing a concentrated acid solution of sodium chloride so that the chlorate is crystallized out. Sodium chlorate is a nonselective soil sterilant used on noncrop land or in combination with triazines, ureas, or other organic herbicides for soil sterilization. It leaches,has foliar contact activity, and in the past, was used widely along railroads. It is flammable when dried on foliage, and many railroad fires occurred when sparks from coal-fired engines landed on sprayed plants. Sodium chloride (table salt) is an example of an herbicide that desiccates and disrupts a plant's osmotic balance. It has been used for nonselective weed control for centuries.

| 相互作用 | 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. |

| Medical Surveillance | Before beginning employment and at regular times after that, for those with frequent or potentially high exposures, the following are recommended: lung function tests.

| 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. |

The exemption will expire and is revoked on the date specified: commodity: wheatExpiration/Revocation Date: 12/31/06.As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. 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. Sodium chlorate is found on List D.
