  • In this study, the authors write: It is worthwhile noting that the lower dose of methoxychlor tested (3 mg/pellet, or approximately 1.2 mg/kg/day) is 4-fold lower than the NOEL used by the U.S. Environmental Protection Agency (EPA) in developing an oral reference dose for methoxychlor.

  • This suggests that an effect on autoimmunity might be a sensitive toxic end point an effect that occurs at doses lower than other adverse effects for methoxychlor, and therefore of particular interest for risk assessment.

    The Autoimmune Epidemic Donna Jackson Nakazawa 2008

  • This suggests, say the authors, that the commonly used pesticide methoxychlor might stimulate autoimmunity at a much lower dose than doses necessary to cause other adverse health effects, and is “therefore of particular interest for risk assessment.”

  • Immunologists, meanwhile, are trying to ascertain what happens to the immune systems of lab mice when they expose them to organochlorine pesticides such as DDT and methoxychlor, the latter having been manufactured as a safer replacement for DDT and now being used widely on food crops, home gardens, and as flea and tick control on pets.

  • In a startling experiment published in 2005, scientist Michael Skinner exposed a pregnant rat to two commonly used industrial chemicals: vinclozolin, a fungicide, and methoxychlor, an insecticide.

    Origins Annie Murphy Paul 2010

  • Transient exposure of a gestating female rat during the period of gonadal sex determination to the endocrine disruptors vinclozalin (an antiandrogenic compound) or methoxychlor (an estrogenic compound) induces decreased spermatogenic capacity (cell number and viability) and increased incidence of male infertility in nearly all males of all subsequent generations examined.
