(Beyond Pesticides, November 19, 2024) Researchers at Stanford University recently published a study in Cancer, an international interdisciplinary journal of the American Cancer Society (ACS), that reveals a correlation for numerous pesticides with increased prostate cancer occurrence and associated death. The study finds that exposure to 22 pesticides is positively associated with prostate cancer. The 22 pesticides include 2,4âD, acephate, azoxystrobin, bifenthrin, carbaryl, chloropicrin, cloransulamâmethyl, cyhalothrinâlambda, diflufenzopyr, diuron, glyphosate, hexazinone, linuron, methyl parathion, pendimethalin, propiconazole, sulfosate, thiamethoxam, thifensulfuron, tribenuron methyl, trifloxystrobin, and trifluralin. (See more on 2,4-D and cancer prevalence here and here.) As prostate cancer is a leading national health concern, the authors investigate agricultural pesticide exposure and compared it to prostate cancer incidence and mortality across counties in the contiguous U.S. âThe geographic variation in prostate cancer incidence and mortality suggests that regional environmental factors, such as pesticide exposure, may contribute to the development of prostate cancer,â the researchers postulate. In comparing countyâlevel associations of 295 pesticides and prostate cancer reports, the authors were able to conduct an environmentâwide association study (EWAS) to determine any statistically significant links. âWe acquired annual estimated total usage data (kg per county) for all pesticides reported and applied to agricultural crops grown […]

(Beyond Pesticides, October 8, 2024) A comprehensive literature review in Endocrines, published in September, amasses hundreds of studies on endocrine-disrupting chemicals (EDCs) that showcase adverse effects on growth, development, reproduction, and metabolism. The authors, a team of scientists and academics from Brazil, shed light on the link between EDC use and thyroid dysfunction, leading to increasingly prevalent illnesses and deadly diseases. Â Â Â EDCs are any synthetic or natural compounds that hinder endocrine system functions and create harmful effects on organisms. These chemicals can impact the thyroid gland, which is vital in producing hormones and plays a role in several body functions. As the researchers state, âSeveral EDCs have been classified as thyroid disruptors, impairing thyroid hormone [TH] production, synthesis, metabolism, transport, and/or actions. Notably, thyroid disorders are the second most prevalent endocrine disease worldwide, with incidence increasing significantly in recent years.â The authors continue, â[S]tudies have correlated this rise in thyroid dysfunctions and cancers with increased exposure to EDCs. Although many EDCs are linked to thyroid dysfunction, this review focuses on the deleterious effects of plasticizers, organochlorine pesticides, and per- and poly-fluoroalkyl substances on thyroid function. These contaminants are commonly found in food, water, and everyday products.â This review helps […]

(Beyond Pesticides, December 8, 2023) Nine pesticides have been found in nearly 40% of nonorganic conventional baby foods tested, according to a study conducted by Environmental Working Group (EWG). The study found no residues of the pesticides studied in a sample of certified organic baby food. While the study finds no traces of the highly neurotoxic insecticide chlorpyrifos, associated with brain damage in children, the chemical has been allowed back on the agricultural market after being removed in 2021âraising an alarm for parents who purchase baby food with ingredients grown in chemical-intensive (âconventionalâ) agriculture. In November 2023, a three-judge panel of the Eighth Circuit Court of Appeals reversed a 2021 U.S. Environmental Protection Agency (EPA) decision to ban chlorpyrifosâ agricultural uses, which came after a 2021 Ninth Circuit Court of Appeals decision found that the agencyâs inaction violated federal pesticide law. Because of its neurotoxic effects on children, EPA had in 2000 negotiated Dow Chemicalâs voluntary cancellation of most residential uses of the chemical, but left virtually all of the chemicalâs agricultural uses in place. While the EWG study focuses on pesticide residues in food and the hazards associated with ingestion of dangerous chemicals, raising alarms, purchasing baby food processed with nonorganic […]

(Beyond Pesticides, March 4, 2022) An article in My London reported by Finn Byrne, finds labeling on conventionally grown fruits and vegetables marked as non-vegan. The non-vegan label shocked many shoppers who buy the produce with chemical-intensive practices, as fruits and vegetables are inherently vegan. However, pesticides used in the production of fruits and vegetables render these foods non-vegan because of the harm that pesticides cause to animals and since a wax coating on fruits and vegetables made of shellac, a resin secreted from female lac beetles and thus non-vegan. Recent studies indicate plant-based diets can mitigate excessive pesticide use and exposure if they are organically grown. However, a plant-based diet reliant on pesticides does little to lessen the health and ecological effects of conventional agriculture. Fungicides are ubiquitous in agricultural and residential settings puts human and animal health at risk. Exposure to fungicides can manifest adverse health effects, including reproductive dysfunction, birth/developmental effects, kidney/liver damage, and cancer. Several researchers find that fungicide use promotes more drug-resistant fungal infections in humans as these fungicides are structurally similar to medical antifungal medications. After investigating fruits and vegetables at various United Kingdom (UK) grocery stores (i.e., Tesco, Morrisons, and Marks and Spencer), the report finds fungicides imazalil and propiconazole present […]

(Beyond Pesticides, September 27, 2016)  Multinational pesticide manufacturer Syngenta Crop Protection was handed a  $1.2 million fine last week for multiple violations of federal pesticide law, according a settlement reached with the U.S. Environmental Protection Agency (EPA). EPA charged Syngenta with three major violations of the Federal Insecticide Fungicide and Rodenticide Act (FIFRA), including: (1) Failure to have repackaging agreement and/or maintain records on registered pesticides; (2) Distributing misbranded pesticides, and; (3) Failure to maintain data submitted for pesticide registration. However, under the consent agreement reached with EPA, the company neither admits nor denies the allegations. The settlement comes at a time of increased scrutiny of Syngenta, as the company is in the process of reregistering the herbicide atrazine, and Chinese National Chemical Corporation (ChemChina) continues its attempts to complete a $43 billion merger. While the plan appears to have cleared U.S. regulatory hurdles, European lawmakers have yet to sign off on the deal. âThe repackaging, sale and distribution of unregistered and misbranded pesticides is illegal and puts people and the environment at risk. Users rely on accurate, up-to-date information about ingredients, directions for use, hazards and safety precautions,â said Anne Heard, Acting Regional Administrator for the Southeast in an […]

(Beyond Pesticides, November 17, 2010) Researchers with the U.S. Geological Survey (USGS) have found a dozen agricultural fungicides in the waters and sediments downstream of farms and orchards in western states. Presented November 8, 2010 at the annual meeting of the Society of Environmental Toxicology and Chemistry (SETAC) in Portland, Oregon, the findings represent the first such data on fungicides in the western U.S. Farmers routinely use fungus-killing compounds to spray or dust food crops, such as strawberries, corn, and soybeans. Some crops receive up to a dozen doses per growing season. Nationwide, fungicide use has risen considerably since the 1990s, reaching 350 million pounds in 2001. However, the environmental prevalence and effects on wildlife and ecosystems, particularly of newer fungicides, are poorly understood, says Kathryn Kuivila, PhD, of the USGS California Water Science Center. Environmental monitoring programs monitor concentrations of few or no fungicides, she notes. The study entitled, âOccurrence of Azoxystrobin, Propiconazole, and Selected Other Fungicides in US Streams, 2005â2006,â documents the occurrence of fungicides in select U.S. streams soon after the first documentation of soybean rust in the U.S. and prior to the corresponding increase in fungicide use to treat this problem. Water samples were collected from […]

(Beyond Pesticides, June 26, 2008) Over 7,500 acres of winter wheat in 15 Kansas counties were sprayed improperly with the fungicide Quilt, forcing the Kansas Department of Agriculture to put an embargo on harvestable wheat from these fields pending further tests. Farmers are legally required to wait 45 days between spraying Quilt and harvesting wheat, but this springâs wet weather encouraged many to ignore the rules. The problem was discovered during a paperwork check of custom applicators, which revealed that some fields had been sprayed as recently as early June. Quilt, manufactured by Syngenta and registered with the Environmental Protection Agency (EPA) in 2003, is a combination of the two active ingredients azoxystrobin and propiconazole. Propinconazole is a fungicide and antimicrobial with registered uses on food and feed crops, turf and ornamentals, as well as wood and material preservation. It is estimated that 1.7 million acres of wheat alone is treated with propinconazole each year. Azoxystrobin was first conditionally registered with the EPA in 1997 for use on turf. Information on the usage of the combination of these two fungicides is unavailable because of the recent registrations. Unfortunately, the USDA has cut funding for pesticide reporting (see Daily News of […]
