(Beyond Pesticides, November 26, 2024) A study in Environment International finds that young children who exhibit higher levels of pesticide metabolites in their urine show more pronounced neurobehavioral problems at the age of ten. Researchers in China document how exposure during early childhood, especially during the sensitive window before the age of two, is linked to hyperactivity/inattention problems such as attention deficit hyperactivity disorder (ADHD). While adding to the body of science connecting pesticide exposure to learning and developmental disorders, this study offers a “novel perspective on characterizing the fluctuation in repeated measurements of multiple environmental chemicals and identifying the potential critical windows,” the authors share. (See previous Daily News coverage here, here, and here.) The researchers analyze data from questionnaires and urine samples through the ongoing Sheyang Mini Birth Cohort Study (SMBCS), which is a long-term prospective cohort study that associates environmental chemical exposure during pregnancy and childhood to negative health effects. This data addresses combined pesticide exposures in young children with neurobehavior analyses at the age of ten to determine any correlation. Within the SMBCS, a total of 1303 pregnant women are enrolled. When the children reached ages one, two, three, six, seven, eight, nine, and ten years […]

(Beyond Pesticides, October 15, 2024) In Environmental Epidemiology, researchers from Columbia University and the University of Southern California, along with representatives from the nonprofit Comite Civico del Valle in Brawley, California, report the heightened risk of wheezing for five- to twelve-year-olds in the rural communities of California’s Imperial Valley. Through a school-based survey, the authors find associations between living near pesticide applications and more wheeze symptoms among the children. According to the authors, residents of the Imperial Valley, which is located near the border between the United States (U.S.) and Mexico, “are primarily Latino, 1 in 3 children live in poverty, and there is a 20% unemployment rate. The county faces poor air quality and excess particulate matter levels. Further, one in five children is diagnosed with asthma and the rate of asthma-related pediatric emergency room visits and hospitalizations is two times the CA state average.” This highlights the disproportionate risk for residents in this area regarding environmental exposure to harmful chemicals. Children are already more susceptible to health complications following pesticide exposure, as they take in greater amounts of toxic chemicals relative to their body weight and have still-developing organ systems. Young children in environments with higher levels of […]

(Beyond Pesticides, May 22, 2024) A study in the journal of Environmental Science and Technology Letters, funded by the National Oceanic and Atmospheric Administration, is the first to find halogenated organic compounds (HOCs) in deep ocean sediment and biota off the coast of California. The test area, known as the Southern California Bight (SCB), is home to historic offshore DDT waste dumping, with part of the SCB designated as a U.S. Environmental Protection Agency (EPA) Superfund site. 49 HOCs were detected in the sediment and biota, many of which are DDT-related and not previously screened for. The presence of these “unmonitored compounds can significantly contribute to the contaminant body burden across a range of marine taxa,” the study states, which leads to impacts on critical food webs and biodiversity. While this study is the first to specifically analyze previously overlooked DDT+ compounds, the results are nothing new. There is a body of science around the bioaccumulation and biomagnification of harmful pollutants that continue to lead to a decline in biodiversity, negative impacts on water and soil, and detrimental human health effects.      To assess the bioavailability of DDT+ and HOCs in the deep ocean food web, this study focused on […]

 (Beyond Pesticides, March 14, 2024) A recent review in the New England Journal of Medicine (NEJM) highlights the urgent need to address the widespread chemical pollution stemming from the petrochemical industry, underscoring the dire implications for public health. Tracey Woodruff, PhD, author and professor at the University of California San Francisco (UCSF), emphatically states in an email comment to Beyond Pesticides, “We need to recognize the very real harm that petrochemicals are having on people’s health. Many of these fossil-fuel-based chemicals are endocrine disruptors, meaning they interfere with hormonal systems, and they are part of the disturbing rise in disease.” Beyond Pesticides echoes this concern, noting that endocrine disrupting chemicals (EDCs) include many pesticides and are linked to a plethora of health issues such as infertility, diabetes, cardiovascular diseases, obesity, early puberty, as well as attention deficit hyperactivity disorder (ADHD), Parkinson’s, Alzheimer’s, and childhood and adult cancers. (See Beyond Pesticides’ Disease database here and news coverage here). The review further calls on the clinical community to advocate for policy changes aimed at mitigating the health threats posed by petrochemical-derived EDCs and climate change. Beyond Pesticides urgently calls for the elimination of petrochemical pesticides and fertilizers and advocates for a systemic […]

(Beyond Pesticides, January 26, 2024) In addition to maternal (mothers) exposure, children experience exposure to pyrethroid insecticides earlier in life as levels significantly increase post-natal (after birth), according to a study published in Frontiers in Public Health. This study is one of the few studies to investigate pyrethroid exposure concentrations in the urine of newborns and children within their first year of life. However, this research reiterates what many other studies demonstrate on pyrethroids’ impacts on children’s health, primarily due to their notorious neurotoxic properties. The findings indicate that exposure to pyrethroids during pregnancy and early childhood exposure has links to adverse health effects, including neurodevelopmental delays (e.g., autism), behavioral issues (e.g., attention deficit [hyperactivity] disorder), and endocrine disruption (e.g., delay in puberty). Pesticide exposure during pregnancy is of specific concern as health effects for all life stages can be long-lasting. Just as nutrients are transferable between mother and fetus, so are chemical contaminants. Studies find pesticide compounds in the mother’s blood can transfer to the fetus via the umbilical cord. Therefore, pesticide exposure during pregnancy affects both the mother and child’s health. Beyond Pesticides has covered a variety of pregnancy risks from pesticides and other toxic chemicals, including these in just […]

(Beyond Pesticides, April 28, 2023) A study published in Science of The Total Environment finds agricultural communities encounter chronic and measurable pesticide exposure regardless of seasonal pesticide applications. Several biomonitoring studies demonstrate people living adjacent to or within agricultural areas often experience elevated levels of organophosphate (OP) insecticides, even while not working directly with OPs. Six dialkyl phosphate (DAP) metabolites (breakdown products) of OPs persist in urine during the spraying and non-spraying seasons. Despite 75 percent of OPs metabolizing into one or more of the six DAPs and excreting within six to 24 hours after exposure, the consistent levels of DAPs in urine highlight continuous exposure beyond regular seasonal pesticide applications. OP compounds have a global distribution, with evaporation and precipitation facilitating long-range atmospheric transport, deposition, and bioaccumulation of hazardous chemicals in the environment. OPs are highly toxic and, as this study shows, residues are consistently present in human and animal urine, as well as blood, tissues, and milk. Considering 90 percent of Americans have at least one pesticide compound in their body, primarily stemming from dietary exposure, including food and drinking water, advocates maintain that current restrictions on their use must adequately detect and assess total chemical contaminants. The study notes, “We suggest that among agricultural communities that experience […]

(Beyond Pesticides, February 9, 2023) Business Insider India reports over 100 infant deaths from pesticide exposure in breast milk. A study by Lucknow’s Queen Mary Hospital links pesticides in breast milk to the death of 111 newborns over the past ten months in the Maharajganj district of northern India. The study is a testament to the effects pesticides can have on the health of individuals, especially vulnerable populations like infants and shows that there is a long way to go before our bodies are void of any bioaccumulated toxic residues. Multiple studies on breast milk throughout the years confirm that toxic chemicals build up in our bodies as breast milk can bioconcentrate or accumulate, a natural phenomenon dubbed chemical “body burden.” Hundreds of chemicals are in blood, urine, breast milk and umbilical cord blood, entering our bodies through diet, personal care product use, and inhalation from air. Many known pollutants (i.e., heavy metals, polychlorinated biphenyl, and pesticides) are chemicals that can move from the mother to the developing fetus at higher exposure rates. Hence, prenatal exposure to these chemicals may increase the prevalence of birth-related health consequences like natal abnormalities and learning/developmental disabilities. Children are particularly vulnerable to the impacts of pesticide exposure as their developing […]
