MIREX Usage And Synthesis
- DescriptionMirex and chlordecone are two separate, but chemically similar, manufactured insecticides that do not occur naturally in the environment. Mirex is a white crystalline solid, and chlordecone is a tan-white crystalline solid. Both chemicals are odourless. Mirex and chlordecone have not been manufactured or used in the United States since 1978. Mirex was used to control fire ants and as a flame retardant in plastics, rubber, paint, paper, and electrical goods from 1959 to 1972. Chlordecone was used as an insecticide on tobacco, ornamental shrubs, bananas, and citrus trees and in ant and roach traps. Mirex was sold as a flame retardant under the trade name Dechlorane, and chlordecone was also known as Kepone. Mirex and chlordecone break down slowly in the environment, and they may stay for years in soil and water. Mirex is not readily decomposed chemically or biologically and is relatively persistent.
- Chemical PropertiesWhite Solid
- Chemical PropertiesMirex is a snow-white crystalline solid.
- UsesAn insecticide for fire ants. Formerly used as a fire retardant for plastics, rubber, paint, paper, electric goods. Reasonably anticipated to be a human carcinogen.
- UsesFormerly as fire retardant for plastics, rubber, paint, paper, electrical goods; insecticide for fire ants.
- General DescriptionOdorless white crystalline solid.
- Air & Water ReactionsInsoluble in water.
- Reactivity ProfileMIREX is sensitive to exposure to sunlight. MIREX may react with strong oxidizers. MIREX reacts with lithium and tertiary butyl alcohol.
- HazardNephrotoxic, highly toxic, possible car-cinogen, teratogen, tumorigen, mutagen, poi-sonous, environmentally persistent, and bioaccu-mulates.
- Health HazardINGESTION, INHALATION, OR SKIN EXPOSURE: Gas- trointestinal irritation with nausea, vomiting, and possible diarrhea. Malaise, headache, CNS excitation with tremor, paresthesias, ataxia, confusion, convulsions, and ventricular fibrillation. CNS depression and central respiratory paralysis may occur.
- Health HazardHighly toxic by ingestion and moderatelytoxic by absorption through skin and inhalation; the toxic symptoms include tremor,ataxia, muscle spasms, and kidney and liverdamage; a teratogenic substance causingadverse reproductive effects; adequate evidence of carcinogenicity in experimentalanimals and a probable human carcinogen(IARC 1996)
LD50 oral (rat): 235 mg/kg
LD50 oral (hamster): 125 mg/kg
LD50 skin (rabbit): 800 mg/kg.
- Fire HazardBehavior in Fire: Supports combustion
- Safety ProfileConfirmed carcinogen with experimental carcinogenic, tumorigenic, and teratogenic data. Poison by ingestion. Moderately toxic by inhalation and skin contact. An experimental teratogen.Experimental reproductive effects. Mutation data reported. A persistent insecticide that is toxic to non-target species. It can bioaccumulate
- Potential ExposureA potential danger to those involved in the manufacture, formulation, and application of the insecticide (particularly effective against fire ants). Also used as a fire retardant in plastics. Not produced in the United States but may be found in imported products.
- CarcinogenicityMirex is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals.
- ShippingUN2761 Organochlorine pesticides, solid, toxic, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.
- IncompatibilitiesIncompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, dichromates.
- Waste DisposalHigh-temperature incineration is recommended. In accordance with 40CFR165, follow recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office.
