Last fall PAN partnered with Justin Matlow, a concerned parent and teacher in the heart of California's strawberry-growing country, to monitor for pesticide drift. Today — to mark Cesar Chavez day — we joined Justin, farmworker advocates and other community partners to release our findings.

What do the data tell us? In short, our Drift Catcher project found that when the cancer-causing pesticide chloropicrin was being applied in a nearby field, concentrations in the air near Justin's Watsonville home were at or above levels considered "of concern" by both state and federal agencies. For the sake of thousands of California families living near strawberry fields, we hope the regulators are paying attention.

I'm not trained as a public health scientist, but I've learned how to decipher epidemiology studies since I started working at PAN — and a good thing, too, because this stuff is interesting.

Case in point: A new study reports that when developing mice are exposed to a pyrethroid insecticide called deltamethrin, it results in impacts on brain chemistry and changes in behavior similar to what's observed in attention deficit hyperactivity (ADHD). Like I said, interesting stuff.

We know that certain environmental contaminants are linked to decreases in children's intelligence quotient (IQ). A recently released seven-minute video, titled "Little Things Matter," explains what scientists know about this association — and why it's important.

Three types of environmental contaminants were discussed in the video. All three have been linked to falling IQs, and all three have been found in the bodies of the U.S. population — both children and adults — by the Centers for Disease Control (CDC). One of the three is a group of commonly used pesticides.

Last week, California's Department of Pesticide Regulation (DPR) released new data from its statewide Air Monitoring Network (AMN). As you've heard from us before, pesticide drift can seriously impact the health and well being of people living in rural communities.

And it is happening. Even with DPR's flawed sampling plan, this latest round of data confirms health-harming drift at monitoring sites across the state. Of the 32 pesticides and five breakdown products assessed, 24 were detected at least once. At one site, the neurotoxic insecticide chlorpyrifos was found in 75% of the air samples taken.

New California data about pesticides in food have been getting a fair amount of attention recently. Earlier this month, the state's Department of Pesticide Regulation (DPR) released results from 2013 food sampling by their Pesticide Monitoring Program.

Unfortunately, DPR’s conclusion that the residues they found on these latest food samples “pose no health risk” is more than a bit misleading. In fact, the trends indicated by the data are that the percentage of food samples containing pesticides has gone up over the past five years — as has the percentage of illegal residues found.
