    Mirex is an organochloride that was commercialized as an insecticide and later banned because of its impact on the environment. This white crystalline odorless solid is a derivative of was popularized to control fire ants but by virtue of its chemical robustness and lipophilicity it was recognized as a bioaccumulative pollutant. The spread of the red imported fire ant was. Kepone, also known as chlordecone, is an organochlorine is a colourless solid. This compound is a controversial insecticide related to Mirex and use was so disastrous that it is now prohibited in the western world, but only after many millions of kilograms had been produced. Kepone is a known persistent organic pollutants (POP), classified among the "dirty dozen" and banned.

    This component, hexachlorocyclopentadiene, was discussed earlier with regards to Kepone o where it was found only in the tests conducted below C. In the Mirex work, however, it was observed only in the C testing. The destruction of Mirex at C is similar to that of Kepone. thermal decomposition behaviors of DDT, Kepone, Mirex, and other chlorinated pestiCides. A block diagram of the DTS is shown in Fig. la. This discontinuous assembly was designed primarily for testing low volatility materials, such as pesticides and other high-molecular-weight chlori­ nated hydrocarbons.

Kepone, also known as chlordecone, is an organochlorine compound and a colourless solid. This compound is an obsolete insecticide related to Mirex and DDT. Its use was so disastrous that it is now prohibited in the western world, but only after many millions of kilograms had been produced. Kepone is a known persistent organic pollutant (POP), classified among the "dirty dozen" and banned.

Kepone, also known as chlordecone, is an organochlorine compound and a colourless solid.

Kepone is a known persistent organic pollutant (POP) that was banned globally by the Stockholm Convention. CARLSON, D.A., KONYHA, K.D., and WHEELER, W.B. Mirex in the environment: Its degradation to Kepone and related compounds.

Science/   Hexachlorocyclopentadiene: Environmental Health Criteria Series No Medicine & Health Science Books @   Neither mirex nor Kepone were detected as photoproducts. Hexachlorocyclopentadiene (hex) (CSCI6) is an intermediate in the manufacture of cyclodiene insecticides, the acaricide dienochlor (see Table 1), and several flame retardants for resins and plastics.

Kepone (decachlorooctahydro-1,2,4-metheno-2H—cyclobuta (6d)pentalenone) is a hydrated chlorinated polycyclic ketone insecticide synthesized by the dimerization of hexachlorocyclopentadiene (Huff and Gerstner, ). It and the closely related mirex are potent ant killers. Badanthadka, H.M.

Mehendale, in Encyclopedia of Toxicology (Third Edition), Uses. The principal end use for Hex is as a key intermediate in the production of chlorinated cyclodiene pesticides, including aldrin, dieldrin, endrin, chlordane, heptachlor, kepone, endosulfan, pentac, isodrin, and cal grade chlordane, for example, has been reported to contain impurities of Hex.

The available data for hexachlorocyclopentadiene indicate that acute and chronic toxicity to freshwater aquatic life occur at concentrations as low as and µg/l, respectively, and would occur at lower concentrations mirex, Kepone, endosulfan (Thiodan®, and Pentac®.

With the exception. After 28 d of exposure to 14 C-labeled Kepone or mirex in water and natural food, bluegills accumulated Kepone and mirex equal to 10 and 12 times the respective exposure concentrations.

Elimination patterns were dissimilar: mirex tended to persist in fish tissue but Kepone did not. Neither Kepone nor mirex was metabolized by bluegills. Mirex and Kepone are also at the heart of a developing controversy in New York State, where both compounds have been found with other toxic.

Mirex is a white crystalline solid, and chlordecone is a tan-white crystalline solid. Both chemicals are odorless. Mirex and chlordecone have not been manufactured or used in the United States since Mirex was used to control fire ants, and as a flame.

Robert J. Kavlock, in Handbook of Pesticide Toxicology (Second Edition), Kepone (Chlordecone) Kepone (decachlorooctahydro-1,2,4-metheno-2H—cyclobuta (6d)pentalenone) is a hydrated chlorinated polycyclic ketone insecticide synthesized by the dimerization of hexachlorocyclopentadiene (Huff and Gerstner, ).It and the closely related mirex are potent.

Hexachlorocyclopentadiene (HCCPD), also known as C, Graphlox, and HRSis an organochlorine compound with the formula C 5 Cl is a precursor to pesticides, flame retardants, and is a colourless liquid although commercial samples appear lemon-yellow liquid sometimes with a bluish vapour. Many of its derivatives proved to be highly controversial, as studies showed them to be.preparations of mirex consists of % mirex and less than × % contaminants, mostly kepone C10Cl (NAS ).

Mirex is comparatively soluble in various organic solvents, such as benzene, carbon tetrachloride and xylene, with solubilities ranging from about 4, toppm (mg/L).

However, mirex has a very low.Kepone in Food from Southeastern United States Kepone could be present in the southeastern United States in areas that were treated with mirex for fire ant control because mirex can degrade into kepone (Carlson et al., ), because kepone has been found to be a co-contaminant of mirex (Pesticide Chemical News, August 4, ), and because.
