Pesticides found in 80% of air samples from California farm communities

By Shannon Kelleher

Almost 80% of air samples collected last year in California’s four most agriculture-intensive communities contained pesticide residues, though the concentrations were “unlikely to be harmful to human health,” according to a recently released state regulatory report.

The California Department of Pesticide Regulation (CDPR) collected 207 air samples at stations in Oxnard, Santa Maria, Shafter and Watsonville once a week throughout 2023, finding at least one of the 40 pesticides they tested for in 163 of the samples, according to the results.

The monitoring stations detected a total of 19 different pesticides in the air samples, including the herbicide pendimethalin and the fumigant 1,3-dichloropronene (Telone), which have both been linked to cancer.

These chemicals and others detected by CDPR have also been linked to nausea, shortness of breath, and eye and respiratory irritation.

Despite being banned in 34 countries, Telone is the third-most heavily used pesticide in California, and CDPR has been criticized for failing to implement regulations that adequately protect mostly Latino farmworkers from the chemical.

The samples were all collected on school grounds, raising concerns among environmental and health advocates about safety risks for children and other vulnerable community members.

“The latest air sampling results continue to show pesticides sprayed on fields drift off site and contaminate the air nearby, a serious concern for those who live, go to school or work near farm fields,” Alexis Temkin, a senior toxicologist at the Environmental Working Group (EWG), said in a press release.

“Sustainable” company behind POM juice among California’s top paraquat sprayers

By Shannon Kelleher

The Wonderful Company, which has been recognized for its sustainability initiatives and owns POM pomegranate juice, Fiji Water, and other popular brands, was among California’s top sprayers of the toxic weedkiller paraquat in 2021, according to a new analysis.

The major agricultural company, which grows pistachios, almonds, and pomegranates, was California’s second largest sprayer of paraquat, which has been linked to Parkinson’s disease. Wonderful accounted for over 13% of the state’s paraquat use, applying almost 57,000 lbs to its fields, according to the analysis published Thursday by the Environmental Working Group (EWG), which drew from data obtained from the California Department of Pesticide Regulation and county agriculture commissioners.

The company’s website states that “environmental sustainability is at the center of our work” and that the company, “in all its operations, must be a deeply responsible steward of the environment, and lead by example to create a sustainable future.” Wonderful has invested $400 million in sustainable agriculture, according to its website.

The Wonderful Company did not immediately respond to request for comment.

Just ten farms and companies in the top agricultural state sprayed 40% of all paraquat used in California in 2021, the analysis found. The biggest paraquat user in the state was the J.G. Boswell Company, a major producer of cotton, tomatoes for paste, and seed crops, which also accounted for over 13% of California’s paraquat use that year.

“Folks have known about paraquat for a while…but I think it’s clear the public doesn’t fully appreciate where these pesticides are being applied and how close it is to their communities,” said Geoff Horsfield, a policy director at the Environmental Working Group who works on pesticides and other agricultural issues.
