[8][9], cis-chlordane (also known as α-chlordane (CAS=5103-71-9)), trans-chlordane (also known as γ-chlordane and beta-chlordane (CAS=5103-74-2)). Currently, EPA has defined a concentration of 24 nanogram per cubic meter of air (ng/M3) for chlordane compounds over a 20-year exposure period as the concentration that will increase the probability of cancer by 1 in 1,000,000 persons.

The half-life of Chlordane in soil has been reported to be approximately one year. Oxychlordane (C10H4Cl8O), the primary metabolite of chlordane, and heptachlor epoxide, the primary metabolite of heptachlor, along with the two other main components of the chlordane mixture, cis-nonachlor and trans-nonachlor, are the main bioaccumulating constituents. ��jAW��2��8�q2��Q�>��T����,cD�K�?qN0��o녒�+1t� }�JD�V�}d. $ Chlordane is a pesticide first registered in the United States in 1948 (1). increased levels of α-chlordane residues in dust (p. trend = 0.04), and a marginally significant trend was noted for increased levels of γ-chlordane (p. trend = 0.06). Available at URL: Center for Disease Control and Prevention (CDC). Due to concerns about environmental damage and human health risks, the U.S. Environmental Protection Agency banned the use of chlordane in 1983, except for controlling termites. [6] Pathways of exposure to chlordane include ingestion of crops grown in chlordane-contaminated soil, inhalation of air in chlordane-treated homes and from landfills, and ingestion of high-fat foods such as meat, fish, and dairy, as chlordane builds up in fatty tissue. Chlordane is a thick liquid that cannot be dissolved in water. Toxhouse.jpg 384 × 236; 45 KB. Bioconcentration . [5] The mixture that is composed of 147 components is called technical chlordane. [citation needed] It has an environmental half-life of 10 to 20 years. Trans-nonachlor and oxychlordane in serum of mothers during gestation has been linked with behaviors associated with autism in offspring at age 4-5. A significant trend for NHL was noted for . endstream endobj startxref National Report on Human Exposure to Environmental Chemicals: Chemical Information: Chlordane. The former production and use of chlordane as a pesticide and termiticide has resulted in the formation of oxychlordane in the environment where chlordane was used. (l�NJ��4� ��ӳsB)Y%��$�"с{�p��~"=�~Ye��z5}��,¸�^q� Though homeowners legally may still use chlordane, Dave Dunbar, an agent with the Lehigh County Extension Service, is taking a cautious approach. Some of the insects that this will kill include bees, wasps, hornets, and dragonflies. Unpublished work (cited in Adeshina and Todd, 1991) reports the mean fat/blood ratio of oxychlordane to be 290/1 among workers who had been exposed to technical grade chlordane. There was a warning on "This Old House" about not using Chlordane. chlordane emulsion per lineal foot in bottom of trench and 1/2 gallon per lineal foot in back fill. If trench is 30 inct,es deep.

The human liver appears to also be vulnerable to damage from exposure to chlordane. Agency for Toxic Substances & Disease Registry (ATSDR). 1.5 Environmental fate Chlordane is very resistant to chemical and biological degradation. Human health risk remains from the persistence of chlordane in the environment and from its metabolite oxychlordane. SMILES . Cis-chlordane-3D-balls.png 2,000 × 1,827; 478 KB. Control Methods. Chlordane appears as a white or off-white crystals when synthesized, but it was more commonly sold in various formulations as oil solutions, emulsions, sprays, dusts, and powders. Chlordane Banned in 1988 In 1983, the EPA (Environmental Protection Agency) banned all uses of Chlordane except for termite control. Being hydrophobic, chlordane adheres to soil particles and enters groundwater only slowly, owing to its low solubility (0.009 ppm). ��Ҍ@��B6� Chlordane is a broad-spectrum insecticide used to control termites and pests on field crops. --Leyo 20:25, 21 August 2016 (UTC) Untitled.

This probability of developing cancer increases to 10 in 1,000,000 persons with an exposure of 100 ng/m3 and 100 in 1,000,000 with an exposure of 1000 ng/m3. Chlordane was available to the general public. [11], In the years 1948–1988 chlordane was a common pesticide for corn and citrus crops, as well as a method of home termite control. ToxFaqs: September, 1995. The chlorine atoms, 7 in the case of heptachlor and 8 in chlordane, and 9 in the case of nonachlor, surround and stabilize the cyclodiene ring and thus these compounds are referred to as cyclodienes. [10] The EPA recommends that children should not drink water with more than 60 parts of chlordane per billion parts of drinking water (60 ppb) for longer than 1 day. Associated health effects include headaches, irritation, confusion, weakness, and vision problems, as well as upset stomach, vomiting, stomach cramps, diarrhea, and jaundice. [29], Chlordane was applied under the home/building during treatment for termites and the half-life can be up to 30 years.

Hexachlorocyclopentadiene forms a Diels-Alder adduct with cyclopentadiene to give chlordene intermediate [3734-48-3]; chlorination of this adduct gives predominantly two chlordane isomers, α and β, in addition to other products such as trans-nonachlor and heptachlor. To remove chlordane from indoor air requires either ventilation (Heat Exchange Ventilation) or activated carbon filtration. %PDF-1.6 %���� Over 50 million persons have lived in chlordanetreated homes. x��&R�E�4j%5�Z0LO߅�P�j�|�Y�� �8"���.
