Environmental Toxins FTW!

This week Pediatrics published the results of a new study linking pesticides with ADHD.  The abstract can be found here, and the following is an excerpt from the full article:
We report an association between urinary DMAP metabolite concentrations, which are indicators of exposure to dimethyl-containing organophosphate pesticides, and increased odds of ADHD for children 8 to 15 years of age. There was a 55% to 72% increase in the odds of ADHD for a 10-fold increase in DMAP concentration, depending on the criteria used for case identification. This association was not explained by gender, age, PIR, race/ethnicity, fasting duration, or creatinine concentration. Whether DAP metabolite concentrations are more strongly associated with a specific subtype of ADHD is unclear, because of the small numbers of cases, although the association was stronger for the predominantly hyperactive/
impulsive subtype. This study should be generalizable to the US population because the NHANES sample is nationally representative, unlike previous studies of groups with higher exposure levels.11–15 With respect to the importance of these findings, organophosphates are among the most widely used pesticides, and the concentrations of DAP metabolites among children did not decrease from 2000 to 2003–2004.
I cannot wait to hear the pesticide industry's response to this.  I cannot wait to see what measures are taken by their representatives to prevent federal regulatory agencies and Congress from taking any action to limit our use of and exposure to pesticides.  If it wasn't so sad it would be downright amusing.

    This morning on the radio they were discussing how the belief that pesticides and herbicides cause cancer and other diseases used to be a fringe phenomenon where only wild-eyed conspiracy theory types and hippies believed it, but now it's become a mainstream everyday belief for most people. I suppose that's progress.

  2. What's sad is that we're not surprised by this kind of news anymore. I think the most common reaction is "well yeah."
