(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, July 26, 2023) An exploratory study published in Environment International adds to the many studies demonstrating residential prenatal pesticide exposure can result in adverse birth outcomes. Residential exposure to five active pesticide ingredients (Ais) fluroxypyr-meptyl, glufosinate-ammonium, linuron, vinclozolin, and picoxystrobin has adverse effects on gestational age (GA), birth weight (BW), mortality after birth, childâs sex, premature development, low birth weight (LBW), small for gestational age (SGA), and large for gestational age (LGA). Pesticidesâ presence in the body has implications for human health, especially during vulnerable life stages like childhood, puberty, pregnancy, and old age. Pesticide exposure during pregnancy is of specific concern as health effects for all life stages can be long-lasting. Birth and reproductive complications are increasingly common among individuals exposed to environmental toxicants like pesticides. The Centers for Disease Control and Prevention (CDC) reports birth defects are the leading cause of infant mortality, with one in every 33 infants born with an abnormality that results in death. Therefore, studies like this can help government and health officials safeguard human health by assessing adverse effects following prevalent chemical exposure. Using a Dutch birth registry from 2009 to 2013, the researchers selected pregnant mothers over 16 years who were living in non-urban areas (who […]

(Beyond Pesticides, March 3, 2020) Pregnant mothers living in areas where carcinogenic pesticides have been used are at increased risk of their child developing an acute form of leukemia, according to research published last month in the International Journal of Hygiene and Environmental Health by researchers at the University of California, Los Angeles. The findings are based on a review of pesticide use data in rural, agricultural areas of California, where many minority, low-income and farmworking communities live. Under current laws, the U.S. Environmental Protection Agency (EPA) permits the use of cancer-causing pesticides with an expectation that a certain number of cancers (anywhere from 1 in 1,000 to 1 in 1,000,000, based on the pesticide in question) should be considered âacceptable risk.â While past studies have shown similar connections between pesticide exposure in the womb and the development of childhood cancer, this is one of the first to utilize geographic information systems (GIS) data, rather than parental interviews on past exposures. Researchers used California public records of cancer incidence from 1998-2011, alongside statewide pesticide use reports (California is the only state to make this information publicly accessible and searchable). A list of 65 pesticides were investigated for their specific connection […]

(Beyond Pesticides, February 20, 2019) Women exposed to DDT during âearly windows of susceptibilityâ in their childhood are at increased risk of developing breast cancer, according to new research published in the Journal of the National Cancer Institute. Nearly 75 years after the chemical was first used in the U.S., and 50 years after its ban, DDT is continuing to adversely affect the health of Americans. The data brings needed attention to the dangers of early-life pesticide exposure, and underlines the need to take a precautionary approach to the introduction of biocides in our environment so that future generations do not suffer from the same mistakes of the past. “What we have learned is that timing really matters. We know that if harmful exposures occur at times when breast tissue is rapidly changing, such as during puberty, they impact breast development in ways that can later result in cancer,” said lead author Barbara A. Cohn, PhD, of the Public Health Institute’s (PHI) Child Health and Development Studies. “The research published today suggests that DDT affects breast cancer as an endocrine disruptor, that the period of time between first exposure and cancer risk seems to be around 40 years–and that other […]

(Beyond Pesticides, February 5, 2019) Linuron, an herbicide registered for use by the U.S. Environmental Protection Agency (EPA), yet recently banned in Europe due to health concerns, appears to trigger inflammatory signals that have been linked to the onset of Multiple Sclerosis (MS). This new evidence, published in the journal Cell by researchers at Brigham and Womenâs Hospital in Boston, MA, indicates that exposure to chemicals and pesticides in the environment may be a risk factor in the development of neurodegenerative diseases. âWe created a platform to systematically investigate the understudied effects of environmental exposures,â said study coauthor Francisco Quintana, PhD. âThe goal of our work is to return results that can guide future epidemiological studies and identify actionable targets.” Researchers began their investigation with 976 chemicals identified by EPAâs ToxCast program, an inventory of compounds that have undergone screening for a battery of laboratory tests. Within that inventory, 75 chemicals, including linuron, were found to interfere with the signaling pathways linked to MS. To confirm the adverse impacts, scientists used the embryos of zebrafish, animals often used as models in laboratory research. The zebrafish embryos were altered to contain low levels of myelin, a protein that protects nerve cells, as […]
