Guest guest Posted May 4, 2006 Report Share Posted May 4, 2006 The findings are fraught with significance - for understanding subgroups affected by organochlorines, for reshaping the notion of " safe " levels. * * * * May 3, 2006 http://pubs.acs.org/subscribe/journals/esthag-w/2006/may/science/kb_pesticide.ht\ ml * Infant pesticide exposure* *Organophosphates may be more dangerous to small children than previously believed.* Some infants may be far more vulnerable to organophosphate pesticides than previously believed, according to a paper published in /Pharmacogenetics and Genomics/ (*2006*, /16/, 183-190 <http://www.jpharmacogenetics.com/pt/re/pharmgen/abstract.01213011-200603000-000\ 04.htm;jsessionid=E7uZJj6opqZVKKwd9WrO2r5n0ym9lTtBoZRrAiRDybipQHo16giD%21-155117\ 8825%21-949856144%219001%21-1>). The new study " raises the question of whether current standards for safe levels of pesticide exposure are sufficiently protective of a vulnerable population, " says Nina Holland, an adjunct professor of environmental health sciences at the University of California, Berkeley, and coauthor of the paper. Current U.S. EPA standards require an extra 10-fold safety factor to protect children <http://www.epa.gov/pesticides/factsheets/kidpesticide.htm> compared with adults. But the new study shows that some newborns may be 65 to 130 times more sensitive to these pesticides than some adults, a level of susceptibility 26 to 50 times higher than previously believed. Of the 130 Latina women who participated in the study with their newborns, more than 40% worked in agriculture during their pregnancies. The Berkeley researchers measured levels of paraoxonase 1, an enzyme that breaks down the toxic metabolites of organophosphates, as a marker for pesticide susceptibility. * Body Burden Case Study: *Organochlorine Pesticides* <http://www.chemicalbodyburden.org/cs_organochl.htm> Chemical body burden is the build-up of synthetic chemicals and heavy metals in our bodies, which can have negative health effects as discussed in this web *...* www.chemicalbodyburden.org/cs_organochl.htm - 20k - <http://www.google.com/search?hl=en & hs=of1 & lr= & safe=off & client=firefox-a & rls=org\ ..mozilla:en-US:official & q=related:www.chemicalbodyburden.org/cs_organochl.htm> *ORGANOCHLORINE PESTICIDES* <http://www.scorecard.org/about/txt/organochlorine_pesticides.html> *Organochlorine pesticides* are man-made organic chemicals. *...* Many *organochlorine* *pesticides* are extremely persistent in the environment and in people's *...* www.scorecard.org/about/txt/*organochlorine*_*pesticides*.html - 19k - <http://www.google.com/search?hl=en & hs=of1 & lr= & safe=off & client=firefox-a & rls=org\ ..mozilla:en-US:official & q=related:www.scorecard.org/about/txt/organochlorine_pes\ ticides.html> *ORGANOCHLORINE PESTICIDES* <http://www.scorecard.org/chemical-profiles/summary.tcl?edf_substance_id=EDF-175\ > Chemical Profile for *ORGANOCHLORINE PESTICIDES* (CAS Number: EDF-175).
