A new study from researchers at the University of California, Berkeley found that when pregnant mothers live within one kilometer of fields where certain pesticides are used, their children are more likely to have lower IQs.
EPA recently released its assessement of the ecological risks posed by the widely used herbicide atrazine. Agency scientists found that current exposures greatly exceed its "levels of concern" for chronic risk for birds, mammals and fish — by 22, 198, and 62 times, respectively. When it comes to wildlife harms, these new findings on atrazine are pretty damning.
A new report by scientists at the University of California, Los Angeles (UCLA) reminds us that we have a lot to learn about the risks of exposure to multiple pesticides at a time. Hmmmm. "Exposure to multiple pesticides at a time" — isn't that what we face in the real world? Yes, it is. Read on.
What, you may ask, is the "spring flush?" In late spring and early summer, large concentrations of herbicides are flushed from croplands. These chemicals — like the herbicide atrazine — then get transported far and wide through surface water systems.
Herbicides are water-soluble and thus have the potential to leach into groundwater supplies as well as streams, lakes and other surface waters. Atrazine is a frequently found contaminant in drinking water supplies throughout the Corn Belt, and every year the spring flush raises concerns over the potential of atrazine spikes in drinking water supplies.
Guess what? Two more studies have confirmed that neonicotinoid insecticides (aka "neonics") are bad for bees. One study documented neonics' impacts on wild bees, which hasn't been looked at much to date. The second found that bees show a preference for neonic-laced food.
A third report from the European Academies Science Advisory Council underscores the importance of the ecosystem service provided by pollinators. The scientific case for taking action to protect bees and other pollinators from neonics just keeps getting stronger.
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.
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.
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.
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.
