Pesticide Near School
Poses Potential Health Risks

Aug 31, 2018


By Megan Kaun and Nichole Warwick

As our children return to school, beauty surrounds many Sonoma County campuses, with bucolic hillsides and sprawling farmland. Yet, unseen toxicity lies within and around these rural schools. For the first time, data about this toxicity is now available to inform parents and the community.

New information about agricultural pesticide use has been released by the California Department of Pesticide Regulation (CDPR) for ~100 public schools and preschools in Sonoma County, which lie within 1/4 mile of farms using pesticides.

This data shows us that many dangerous pesticides are in use in very close proximity to schools. It also provides us with an opportunity to engage in an informed conversation with schools and farmers. 

Toxic Pesticide Use Near Sonoma County Schools

Pesticides, including weed killers (herbicides), insecticides, and fungicides, are used commonly in Sonoma County. Synthetic or man-made pesticides are long-lasting toxicants in the environment, linked to many human health problems. Children are particularly vulnerable to toxicants like pesticides. Many are known carcinogens (cancer-causing) and endocrine disruptors, which affect development and reproductive health in both males and females.

Vineyards dominate agriculture near schools, and the vast majority (around 98%) of Sonoma County vineyard land is managed using synthetic pesticides. Though the Sonoma County Winegrowers Association has a goal to certify all vineyards “Sonoma Sustainable” by 2019, certification does not require vineyards to reduce pesticide use.

The most commonly-used herbicide by farmers in Sonoma County is glyphosate, the active ingredient in RoundUp. Thirty-seven (37) tons of glyphosate were used on Sonoma County farms in 2016. Glyphosate was listed by California Proposition 65 as a known carcinogen in July 2017. In August 2018 a jury ordered Monsanto, the maker of RoundUp, to pay a school maintenance worker with terminal non-Hodgkins lymphoma $289.2 million for failure to warn consumers that exposure toRoundUp weedkiller can cause cancer. Low dose exposure to glyphosate is also associated with birth defects, endocrine disorders, and liver/kidney disorders. This pesticide has been used for decades by people assuming it was “safe as salt”. This should remind us that pesticides are designed to kill and should be avoided wherever possible.

Other commonly used pesticides in Sonoma County are linked to serious health effects. For example, the active ingredient chlorpyrifos, present in products Renegade andLorsban Advanced, has been associated with developmental disabilities and neurotoxicity in children. In August 2018, a US federal appeals court ordered the EPA to ban chlorpyrifos. Other common products like Torino, Luna Experience, Sovran, Rally 40, Goal Tender, andPH-D Fungicide all contain active ingredients considered to be “Bad Actors” (carcinogens, reproductive, developmental, or neurotoxins) by the Pesticide Action Network (PAN). All of these products are currently used within 1/4 mile of Sonoma County schools.

Children are More Vulnerable

Children are particularly vulnerable to the impacts of toxic exposure, including lower IQs, birth defects, developmental delays, autism, ADHD, and cancer. Immediate effects of pesticide exposure can mimic allergies or viral/bacterial infections and include headaches, difficulty breathing, asthma, unusual behaviors and sensory sensitivities, etc. Local doctors like Michelle Perro, MD, author of What’s Making our Children Sick routinely treat neurological and behavioral problems in children by limiting exposure to pesticides in food and the environment.

Sonoma County has the 3rd highest childhood cancer rate of California’s 58 counties, according to the Lucile Packard Foundation for Children’s Health. (Humboldt is 1st, Solano is 2nd, and Sonoma is tied with Napa for 3rd.) With statistics like this, it is so important to examine all potential risks and threats to our children’s health and well-being. The interface of schools and farms poses extraordinary health risks.

KAUN & WARWICK’S CANCER FEAR-MONGERING ― Glyphosate herbicide can cause cancer ?!?! WRONG ! The researchers at the National Cancer Institute ( NCI ) have concluded that ― glyphosate was NOT statistically significantly associated with cancer. This large long-term research was published in the Journal of the National Cancer Institute ( JNCI ) on November 9th, 2017. This was the largest research study of agricultural workers in history, a gold standard, over the longest period of time. It definitively demonstrated in a real-world environment that glyphosate DOES NOT cause cancer. NCI has the essential expertise on this issue, and NOT Kaun & Warwick.
