Pesticides Linked to ADHD

Reuters writes that Pesticides tied to ADHD in children in U.S. study:
Researchers tracked the pesticides’ breakdown products in children’ urine and found those with high levels were almost twice as likely to develop ADHD as those with undetectable levels.

The findings are based on data from the general U.S. population, meaning that exposure to the pesticides could be harmful even at levels commonly found in children’s environment.

“There is growing concern that these pesticides may be related to ADHD,” said researcher Marc Weisskopf of the Harvard School of Public Health, who worked on the study.

“What this paper specifically highlights is that this may be true even at low concentrations.”

Organophosphates were originally developed for chemical warfare, and they are known to be toxic to the nervous system.

Then they try to greenwash the problem by saying to wash food before eating. Sure, that will help a bit, but many of the chemicals are inside the food, not just on it.

The problem is that by waging chemical warfare on weeds, we’re waging chemical warfare on ourselves.


PS: Glysophate (RoundUp) is an organophosphate.

Pesticides in Children

Carolyn Butler writes in the NYTimes about Hidden hazards in fruits and veggies:
Researchers at the University of Montreal and Harvard University looked for organophosphate pesticide metabolites, an indicator of pesticide exposure, in the urine of 1,139 kids ages 8 to 15 and found that close to 95 percent had at least one of these chemical byproducts in their system. Those with the highest levels were 93 percent more likely to have received an ADHD diagnosis than children with none in their system. Those with above-average levels of the most common organophosphate byproduct — they made up a third of the whole group — were more than twice as likely as the rest to have ADHD.

So what fruits and vegetables are pesticides found in?

If you’re concerned, there is a wealth of information establishing just how many chemicals we consume, starting with the Department of Agriculture’s Pesticide Data Program, which tests thousands of food samples a year, tracking specific residue levels. According to its most recent report in 2008, for example, a type of organophosphate called malathion was detected in 28 percent of frozen blueberries, 25 percent of fresh strawberries and 19 percent of celery. “It’s easy to have a dozen exposures [to different pesticides] in the course of a day,” says Richard Wiles, senior vice president for policy at the Environmental Working Group, a Washington-based environmental advocacy group .

I don’t know why the NYTimes can’t be bothered to provided links, such as the actual Pediatrics journal article, or the USDA Pesticide Data Program. That’s some hard data.
