Methoxychlor trichloroethane

In a model aquatic ecosystem, methoxychlor degraded to ethanol, dihydroxy ethane, dihy-droxyethylene, and unidentified polar metabolites (Metcalf et al, 1971). Kapoor et al. (1970) also studied the biodegradation of methoxychlor in a model ecosystem containing snails, plankton, mosquito larvae, Daphnia magna, and mosquito fish Gambusia affinis). The following metabolites were identified 2-(/5-methoxyphenyl)-2-(p-hydroxyphenyl)-l,l,l-trichloroethane, 2,2-bis (p-hydroxyphenyl) -1,1,1 -trichloroethane, 2,2-bis (p-hydroxyphenyl) -1,1,1 -trichloroethylene,...

The groups on the phenyl rings appear to have some effect on the reductive dechlorination of the trichloroethane. Thus, o,p -DDT is de-chlorinated reductively to o,p -DDD by mechanisms and rates similar to the reductive dechlorination of p,p -DDT 17, 25). In contrast, Mendel et al. 17) were unable to obtain reductive dechlorination when the phenyl chlorine atoms of p,p -DDT were replaced by ethyl or methoxy groups. It is interesting, however, that they were unable to recover completely the methoxychlor. This indicates anaerobic degradation of this compound by some other route. 

Methoxychlor is a reproductive toxicant. Exposure of young adult male rats to methoxychlor reduced their serum testosterone levels (Murono et al. 2006). It metabolized in the liver into 2,2-bis(p-hydroxyphenyl)-l,l,l-trichloroethane and both methoxychlor and its metabolite were found to exhibit weak estrogenic and antiandrogenic activities. Flynn etal. (2005) have reported that long-term exposure to methoxychlor in diet altered the sexually dimorphic behavior in young rats of both sexes. The study indicated that consumption of sodium solution increased in rats from such exposure. The toxicity of methoxychlor, particularly in the central nervous system, may be attributed to its inhibition of brain mitochondrial respiration which probably is caused by an increased production of reactive oxygen species (Schuh et al. 2005).

An individual method was described for the determination of 2,2-bis(p-methoxyphenyl)-1,1,1-trichloroethane isomer in the insecticide methoxychlor by TLC. The presence of this isomer in technical grade and emulsifiable concentrate of the methoxychlor could be established by this method, in which silica gel plates were developed with n-pentane-ether (9 1) (53a).
