(Beyond Pesticides, May 31, 2022) Fifty years after the banning of DDT, the notorious insecticide is still harming iconic birds of prey along the California coastline. According to research published in Environmental Science and Technology, California condors and marine mammals along California’s coast are contaminated with several dozen different halogenated organic compounds (hazardous, often-chlorinated chemicals) related to DDT, chlordane, and other now-banned legacy chemicals. The findings highlight the incredible importance of addressing these original “forever chemicals,” and making certain that we do not continue to repeat the mistakes of the past with new and different, yet equally dangerous, chemistries. Between 1947 and 1971, the Montrose Chemical Corporation of California, the largest historical producer of DDT, released over 1,700 tons of DDT into the LA sewer system, which eventually made its way into the Pacific Ocean. During this time, several other companies discharged PCBs, leading to further chemical contamination of land and sediment. As recent as April 2021, scientists discovered 25,000 barrels likely containing DDT near Catalina Island along the southern California coast. These releases have resulted in serious environmental and health problems throughout the coastal food chain. Yet, as the present study shows, scientists are only beginning to understand the […]

(Beyond Pesticides, April 21, 2022) A literature review published in Royal Society finds that ‘inert’ ingredients’ in pesticide formulations adversely affect the health of bees and other wild pollinators. Inert ingredients, also known as “other” ingredients, and not disclosed by name on pesticide product labels, facilitate the action of active ingredients targeting a specific pest. Although both ingredients have chemical and biological activity, most studies on agricultural chemical toxicity focus on the active ingredient, assuming that inert ingredients are “nontoxic.” The U.S. Environmental Protection Agency (EPA), in regulating pesticides, assesses the toxicity of individual active ingredients on bees through various testing methods. However, there are no requirements for EPA to test inert ingredients to the same degree, despite evidence demonstrating these chemicals harm pollinators. Moreover, EPA does not require pesticide manufacturers to disclose the inert ingredients used in any product as the information is confidential. Both wild and commercial bees and other pollinators encounter multiple stressors, including pesticides, parasites, and poor nutrition, that act together to increase the risk of bee mortality. Therefore, reviews like these highlight the need for pesticide testing to consider the effects of all product ingredients, regardless of perceived toxicity. The researchers caution, “We argue that ‘inert’ ingredients […]

(Beyond Pesticides, April 19, 2022) Both houses of Maine’s legislature have just approved a bill that would, by 2030, ban pesticides that contain PFAS chemicals — the so-called “forever chemicals.” The bill’s next stop is the Appropriations Committee, for approval of $200,000 in annual funding to enact the bill; if successful there, it will move to the desk of Maine Governor Janet Mills for her signature. The legislation is one of a suite of lawmaker efforts in the state to address the growing PFAS problem with which localities across the U.S. are struggling. In this Daily News Blog article, Beyond Pesticides continues its coverage of the scourge of PFAS chemicals, particularly as it relates to pesticide use and the use of fertilizers made from PFAS-contaminated “biosludge” from municipal treatment facilities. PFAS — “per- and poly-fluoroalkyl substances” — are any of a family of more than 9,000 synthetic chemicals, invented in, and widely deployed since, the 1950s in a multitude of industrial and consumer products. PFAS molecules are made up of a chain of linked carbon and fluorine atoms; the carbon–fluorine bond is one of the strongest chemical bonds that exists, which means that these compounds do not break down in the […]

(Beyond Pesticides, March 29, 2022) Plastic storage barrels contaminated with polyfluoroalkyl substances (PFAS) may be in violation of the Toxic Substances Control Act (TSCA), according to an open letter released by the U.S. Environmental Protection Agency (EPA) last month. Manufacturers, producers, processors, distributors, users, and those that dispose of fluorinated High-Density Polyethylene (HDPE) containers or other similar plastics that form PFAS as a byproduct were notified in the letter of requirements under federal law. The notice comes two years after EPA was first alerted to the presence of PFAS in a mosquito pesticide used by the state of Massachusetts known as Anvil 10+10. “Today’s action will help ensure that responsible parties are held accountable for any future PFAS contamination affecting communities,” said Assistant Administrator for the Office of Chemical Safety and Pollution Prevention Michal Freedhoff, PhD. While the agency believes its letter represents progress, health advocates note that there has been no meaningful regulatory action from the agency on this issue. In January 2021, a year after receiving notice from Public Employees for Environmental Responsibility (PEER) on the presence of PFAS on Anvil 10+10, EPA confirmed the finding. At the time the agency did nothing, while acknowledging, “the need to […]

(Beyond Pesticides, March 2, 2022) Covid (SARS-CoV-2) is being detected in wastewater, sludge, and biosolids, providing a “safe haven” for the virus and creating a health risk for wastewater workers and farmers. Published in Geoscience Frontiers, an international team of researchers systematically reviewed the available literature on the prevalence of pandemic coronavirus in wastewater in order to better determine risks to workers and public health. The timely review comes as many communities and states are reevaluating their use reclaimed human effluent due to a range of toxic contaminants, including per and polyfluoroalkyl substances (PFAS). Researchers found 20 articles from published literature that met the criteria for their review. Each of three environmental materials –wastewater effluent, sludge, and biosolids were analyzed for the presence of Covid. Effluent is the liquid that remains after a sewage treatment process, sludge is organic matter separated from effluent, and biosolids are the fully processed product that is then often applied to farm fields. Of the three materials, sludge contained the highest prevalence of covid RNA, followed by biosolids and then effluent, according to modeling of the data employed by researchers. Covid amounts were found to be related to the number of infected individuals living within […]

(Beyond Pesticides, February 25, 2022) Together, governments of the world over are spending at least $1.8 trillion annually — 2% of global gross domestic product — on subsidies that drive the destruction of ecosystems and species extinction, and exacerbate the climate crisis. This news comes from a study commissioned by The B Team and Business for Nature, and released in a joint brief, Financing Our Survival: Building a Nature Positive Economy through Subsidy Reform. The Business for Nature website offers a remedy to this entropy: “With political determination and radical public–private sector collaboration, we can reform these harmful subsidies and create opportunities for an equitable, nature-positive and net-zero economy.” To that end, the two organizations have issued, in their brief, calls to action to multiple sectors, including one to the governments participating in the coming UN Biodiversity Conference (COP15): “Adopt a clear and ambitious target within the Global Biodiversity Framework . . . that commits governments to redirect, repurpose, or eliminate all environmentally harmful subsidies by 2030 and increase positive incentives to enable an equitable, net-zero, nature-positive world.” A press release from The B Team reports that the fossil fuel, agriculture, and water sectors are the recipients of more than […]

(Beyond Pesticides, February 22, 2022) Regulation of toxic chemicals must recognize the reality that, “The cocktail of chemical pollution that pervades the planet now threatens the stability of global ecosystems upon which humanity depends,” as stated by The Guardian. When the Environmental Protection Agency (EPA) recognizes the dangers of a toxic chemical—especially one persistent in the environment—it must take immediate action to prevent further contamination. So, allowing the phase-out of chemicals with long residual life can extend the poisoning and contamination for generations. Tell EPA to immediately ban all uses of pentachlorophenol and other toxic wood preservatives. Tell Congress to ensure that EPA does its job.  There is an ongoing crisis, widely reported, posed by the nearly ubiquitous presence of “forever chemicals”—poly- and perfluoroalkyl substances (PFAS) and their relatives. A report by the Centers for Disease Control and Prevention (CDC) finds that 97% of Americans have PFAS in their blood. The Safer States Network finds that more than 210 bills will be considered in at least 32 states in 2022 to try to address the problem. Even the U.S. Environmental Protection Agency has confirmed that ‘forever chemicals’ are contaminating containers that store pesticide products, and subsequently the products themselves. PFAS […]

(Beyond Pesticides, February 18, 2022) A new analysis conducted by Safer States, and reported on by Environmental Health News (EHN), concludes that in 2022, at least 32 states will consider 210 potential laws to ban or restrict one category of so-called “legacy” chemicals — the PFAS (per- and polyfluoroalkyl substances) family of compounds. “Legacy” or “forever” chemicals are those whose historical use, including many decades ago in some instances, has led to their toxic persistence in the environment and in organisms. In recent years, scientists, health and environment advocates, and policy makers have begun to recognize these as very serious contaminants, and to call attention to their ubiquity and impacts. Beyond Pesticides has identified multiple instances of such “legacies” (including those related to the production of pesticides and particularly, the infamous DDT), and will here discuss both PFAS, and concerns about such legacy chemicals as they may impact food producers. The term “legacy” often connotes the ongoing influence or impact — generally salutary — of an individual’s activity, or a set of principles or activity inherited from one’s forebears. It is an apt description, minus the “salutary” part, for legacy chemicals — toxic “gifts that keep on giving” via persistent contamination […]

(Beyond Pesticides, January 21, 2022) The bottom-line conclusion of a recent study is that global chemical pollution has now exceeded a safe limit for humanity. As reported by The Guardian, “The cocktail of chemical pollution that pervades the planet now threatens the stability of global ecosystems upon which humanity depends.” Published in Environmental Science & Technology, the research paper asserts that the creation and deployment (into the materials stream and environment) of so many “novel entities” (synthetic chemicals) is happening at a pace that eclipses human ability to assess and monitor them. The study team calls this exceedance of the “planetary boundary” of such chemical pollution “the point at which human-made changes to the Earth push it outside the stable environment of the last 10,000 years.” According to Beyond Pesticides, which covers pesticide (and other kinds of) chemical pollution, these results underscore a grim twin reality to the human-caused climate emergency, and should be a dire warning on the state of our shared environment and a time for systemic movement to eliminate fossil fuel-based pesticides and fertilizers. Hailing from Sweden, the United Kingdom, Canada, Denmark, and Switzerland, members of the research team define “novel entities” as those compounds and materials […]

(Beyond Pesticides, November 12, 2021) Omnivorous readers may have encountered an article, in the November 15 issue of The New Yorker magazine, titled — at best misleadingly, and certainly sensationally — “The Great Organic-Food Fraud.” The subhead comports with the tone of the headline: “There’s no way to confirm that a crop was grown organically. Randy Constant exploited our trust in the labels — and made a fortune.” The piece, by Ian Parker, tells a complex tale of the machinations of dishonest and greedy people who saw, in the commerce in organic grains, an opportunity to misrepresent nonorganic crops as organic and make a boatload of money in doing so. What the article fails to do is render any comprehensive picture of how National Organic Program certification and inspection work, and the underlying principles, values, and standards in federal law (the Organic Foods Production Act), nor does it review either the benefits of organic agriculture broadly or the massive harmful impacts of conventional, chemical-intensive agriculture in the U.S. Beyond Pesticides provides ballast, in this Daily News Blog article, to the failings of the New Yorker article and the damage it might do to the organic movement. It is worth noting […]

(Beyond Pesticides, November 3, 2021) With a significant and increasing share of the U.S. population reporting sensitivities to certain chemicals, a team of researchers at University of California (Irvine), University of Texas (San Antonio), and the Massachusetts Institute of Technology is working to better understand how these symptoms develop. Although referred to by several names over the years, including Multiple Chemical Sensitivity (MCS) and Idiopathic Environmental Illness, medical professionals are now referring to the disease as Chemical Intolerance, or Toxicant Induced Loss of Tolerance (TILT), to better represent the disease process and range of nervous system symptoms that individuals develop to low level chemical exposures. “We established evidence of this previously understudied disease process,” said Shahir Masri, Sc.D, at University of California, Irvine. “Our insights will help public health scientists, physicians and policymakers better understand how to minimize harmful exposures and prevent future disease.” TILT is characterized by a two-step process. First, there is an “initiation exposure event,” whereby an individual is either repeatedly exposed to low levels of certain chemicals, or experiences a major exposure incident. In the second stage, affected individuals are “triggered” even by minute exposures, not only to the chemical that affected them in the first […]

(Beyond Pesticides, October 7, 2021) The Arizona State Auditor General reports a lack of groundwater monitoring for pesticides and other contaminants by the Arizona Department of Environmental Quality (ADEQ). For over six years, the agency failed to monitor groundwater and soil for agricultural pesticide contamination. Furthermore, the agency did not implement key groundwater monitoring processes over four years, despite law requirements. This lack of waterway monitoring resulted in an increased number of impaired surface waters across the state.   Pesticide contamination in waterways is historically commonplace and widespread throughout U.S. rivers and streams, with at least five or more different pesticides present in 90 percent of water samples. Thousands of tons of pesticides enter waterways (e.g., rivers, streams, lakes, oceans) around the U.S. from agricultural and nonagricultural sources, contaminating essential drinking water sources, such as surface water and groundwater. Reports like these are essential in determining appropriate regulatory action to protect human, animal, and environmental health from chemical toxicant contamination. The report states, “[The] Department has not developed all required aquifer water quality standards, conducted key ongoing groundwater monitoring of the State’s aquifers, monitored for agricultural pesticides in groundwater and surrounding soil, or reduced the number of impaired surface waters in the State, limiting its […]

(Beyond Pesticides, September 22, 2021) Health and environmental organizations are urging the U.S. Environmental Protection Agency (EPA) and state pesticide regulators to immediately stop the use and sale of dangerous and misbranded Eco-MIGHT and W.O.W. (Whack Out Weeds!) products, falsely labeled as 25(b) minimum risk. Recent laboratory testing by the state of California found the presence of hazardous pesticides, including glyphosate, bifenthrin, permethrin, cypermethrin, and carbaryl in these products. “From organic farmers to municipal landscapers and home gardeners, consumers employing minimum risk products are working intentionally to avoid the dangers associated with toxic pesticide exposure,” said Jay Feldman, executive director of Beyond Pesticides. “It is critical that EPA and state regulators coordinate to ensure the integrity of the minimum risk program.” Coordination is critical yet reports indicate that EPA is falling down on the job. The issue first came to light in late July, when the California Department of Food and Agriculture’s (CDFA) State Organic Program issued a Stop Use Notice to farmers alerting them to adultered Eco-MIGHT and W.O.W products. The products make a range of claims, marketed as “organic,” “natural,” “glyphosate-free,” and “non-toxic and safe.” As CDFA Secretary Karen Ross noted, “It is imperative that we alert California […]

(Beyond Pesticides, September 16, 2021) A study published in Chemosphere finds persistent organic pollutants (POPs), including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs), are present in the serum and placenta of pregnant mothers, as well as multiple fetal organs. Many studies indicate prenatal and early-life exposure to environmental toxicants increases susceptibility to diseases, from learning and developmental disabilities to cancer. However, this study is one of the first to demonstrate the presence of chemical toxicants in fetal tissue that are not present in maternal serum or placental samples. Prenatal development is one of the most vulnerable periods of exposure when the fetus is most susceptible to the harmful effects of chemical contaminants. Therefore, studies like these help government and health officials better identify fetal exposure contaminants and subsequent health concerns otherwise missed by current chemical monitoring methods. The researchers note, “These findings call for further evaluation of the current matrices used to estimate fetal exposure and establish a possible correction factor for a more accurate assessment of exposure in utero. We disclose the full data set on individual exposure concentrations to assist in building in silico models for prediction of human fetal exposure to chemicals.” Several studies associate early-life exposure to toxic chemicals […]

(Beyond Pesticides, September 2, 2021) A McMaster University (Canada) study demonstrates exposure to the recently banned, commonly used insecticide chlorpyrifos promotes obesity development, even at low doses. Obesity generally occurs following a caloric imbalance between food intake, absorption, and energy expenditure. Although various factors can promote obesity, researchers suggest environmental toxicants like chlorpyrifos play a role in obesity development through protein/enzyme suppression. According to the Center for Disease Control, 42 percent of the U.S. population is obese and at risk for type two diabetes, cardiovascular (heart) disease, stroke, several cancers, and other critical health issues. Therefore, research like this highlights the significance of investigating how toxic chemical exposure can impact health to prevent adverse disease outcomes. Researchers note, “These studies suggest that the effects of environmental toxicants on the development of obesity may have been underestimated as all studies to date have been conducted in mice housed at RT [room temperature]. Future studies examining the mechanisms driving reductions in β-AR [beta adrenergic receptors] signaling and whether there are associations between BAT [brown adipose tissue] metabolic activity and CPF [chlorpyrifos] in humans will be important.” Several environmental pollutants have links to obesity development via the effects on gut health, endocrine (hormone) and metabolic system, […]

(Beyond Pesticides, July 7, 2021) Organic food consumption among children is associated with higher scores on tests measuring fluid intelligence and working memory, research published in the journal Environmental Pollution finds. The study, conducted by Spanish researchers based at the Barcelona Institute for Global Health, took an exposome approach to environmental exposures, looking at a totality of all environmental hazards that children encounter, rather than investigating individual lifestyle factors one by one. As study co-author Jordi Júlvez, PhD, notes, “healthy diets, including organic diets, are richer than fast food diets in nutrients necessary for the brain, such as fatty acids, vitamins and antioxidants, which together may enhance cognitive function in childhood.” Researchers began their study by selecting mother-child pairs enrolled in the Human Early-Life Exposome (HELIX) Project, a pan-European study with projects in multiple European countries. Nearly 1,300 healthy children aged 6-11 were included in the study, as researchers already had pregnancy data and urine samples stored on the participants. To determine other environmental exposures, home addresses were evaluated for their level of pollution and proximity to natural spaces, and children and their mothers were given tests that included a questionnaire on lifestyle factors, including parents smoking and alcohol use, […]

(Beyond Pesticides, June 10, 2021) Exposure to toxic chemicals decreases egg count and increases infertility risk among women, according to a study published in Environment International. Since 2014, U.S. fertility rates have been decreasing, with many attributing the decline to older age pregnancies. However, several findings demonstrate that exposure to environmental pollutants, like persistent organic pollutants (POPs) from the industrial and agriculture industry, contributes to a decline in fertility rates. Scientists and health officials already associate exposure to POPs, like pesticides, with adverse impacts on male fertility, including reduced sperm count, quality, and abnormal sperm development. Therefore, it is essential to understand how exposure to toxic chemicals in the environment affects reproductive success, especially among women who can transfer contaminants to the fetus via the umbilical cord. The researchers note that these findings should urge government and health officials to reexamine chemical safety concerning reproductive health, and “strongly encourage [them] to study mechanisms behind POP-associated infertility in women in more detail.” Researchers examined ovarian egg reserve size in pregnant women directly by examining the density of follicles and immature eggs in ovarian tissue and indirectly via serum anti-Müllerian hormone (AMH). Using AMH serum samples, researchers assessed concentration levels of 31 POPs: nine organochlorine pesticides (OCPs), ten polychlorinated […]

(Beyond Pesticides, June 8, 2021) Biosolid-based fertilizer products like Milorganite, often sold to consumers as “organic,” are contaminated with dangerous PFAS chemicals, according to a study published by Sierra Club and Ecology Center. Biosolids, also known as sewage sludge, have been found in the past to contain residues of hazardous pesticides, heavy metals, antibiotics and other pharmaceuticals, personal care products, and a range of other toxicants. While the latest news may not be surprising for careful shoppers who have long avoided biosolid fertilizers, none of these risks are relayed to consumers on fertilizer packages. With fertilizer regulations failing the American consumer, it becomes more important than ever to seek out certified organic fertilizer products. Sierra Club and Ecology Center looked at nine fertilizer products, each produced from the sewage sludge of a particular American city. For instance, Milorganite, perhaps the most well-known biosolid sludge fertilizer, is derived from the Milwaukee, Wisconsin sewage treatment system. Other products were derived from locations including Sacramento, CA (Synagro); Tacoma, WA (TAGRO); Madison, GA (Pro Care); Las Vegas, NV (Ecoscraps); Eau Claire, WI (Menards Premium Natural Fertilizer); Jacksonville, FL (Greenedge); North Andover, MA (Earthlife); and Washington, DC (Cured Bloom). As the report notes, many of […]

(Beyond Pesticides, May 5, 2021) As periodical cicadas begin to emerge throughout the central and eastern United States, many may be tempted to put a halt to their noisy mating calls by reaching for a spray bottle of pesticide. But besides violating local noise ordinances, cicadas are relatively harmless and play a critical ecological role. Environmental organizations are urging U.S. residents and communities not to spray cicadas with pesticides, noting that pesticide hazards will last longer than Brood X cicadas.   Reports indicate that pesticide applicator groups and businesses agree that there is no need to spray for periodical cicadas. “We really want people to understand and know that pesticides are not the answer, which sounds really funny coming from a pest control company,” Frank Meek, a manager at Orkin, told CNET. “Pesticides are not the thing to use on this insect. They don’t work for it, and it’s a waste of product, and it’s a danger to the environment just to spray down because you’re afraid of the cicadas.” But while environmental groups and frontline applicators are working to educate the public over the futility of spraying, pesticide manufacturers like Ortho are encouraging homeowners to spend their money on […]

(Beyond Pesticides, April 22, 2021) Past maternal exposure to the pesticide dichlorodiphenyltrichloroethane (DDT) during pregnancy can increase the risk of breast cancer and cardiometabolic disorders (e.g., heart disease, obesity, diabetes) up to three successive generations, according to a new study published in Cancer Epidemiology, Biomarkers & Prevention. Although previous studies highlight early life or in utero exposure to DDT increasing breast cancer risk later in life, this study is the first to note generational effects on grandchildren’s health. DDT continues to adversely affect the health of the U.S. population, nearly 50 years after its ban. However, this ban is not global, as many countries still use or manufacture the chemical compound. Furthermore, residues of DDT metabolite, DDE, continue to readily contaminate food and water worldwide. Therefore, studies like these highlight the need to investigate how first-generation pesticide exposure can impact future generational health in order to prevent adverse health outcomes, especially during sensitive developmental periods (i.e., in utero, infancy/childhood). The study researchers note, “Discovery of actionable biomarkers of response to ancestral environmental exposures in young women may provide opportunities for breast cancer prevention.” To assess the association between multi-generational health risks and chemical exposure, researchers used the Public Health Institute’s Child […]

(Beyond Pesticides, April 20, 2021) Roundup products manufactured by Bayer-Monsanto kill exposed bumblebees at high rates, according to a new study published in the Journal of Applied Ecology, which points to undisclosed inert ingredients (those that typically make up a majority of the product formulation) as the primary culprit. Roundup products have become synonymous with their main active ingredient glyphosate, but Bayer-Monsanto has been quietly reformulating its flagship product with different herbicides in a likely attempt to rebrand as glyphosate cancer lawsuits drag down the company’s performance. The new study reveals that these new Roundup products present the same hazards to pollinators as glyphosate-based formulations, raising important questions about the pesticide regulatory process. Researchers based at Royal Holloway University of London, UK conducted the present study to better understand the hazards posed by herbicides often characterized as “bee safe” to the public. To do so, 10 healthy bumblebee (Bombus spp) colonies were retained, split into small groups, and sprayed with a particular herbicide. Four different herbicide products were employed, including: i) Fast Action Roundup® Ready‐To‐Use (containing glyphosate); ii) Roundup® Speed Ultra (containing acetic acid and no glyphosate); iii) Weedol® Gun! Rootkill Plus (containing glyphosate) and; iv) Roundup® ProActive (contains glyphosate […]

(Beyond Pesticides, April 15, 2021) Gestational (during pregnancy) and childhood exposure to per- and polyfluoroalkyl substances (PFAS) increase cardiometabolic risk, or the risk of heart diseases and metabolic disorders, later in life, according to a Brown University study published in Environment International. Past studies associate exposure to chemical pollutants with increased susceptibility to adverse health effects during critical fetal and childhood developmental periods. Some of these health effects are cardiometabolic risk factors, including obesity, insulin issues, abnormal blood pressure, that increase the risk of developing cardiovascular disease (CVD) and metabolic disorders (e.g., type 2 diabetes). PFAS are of particular concern as these endocrine-disrupting chemicals are common in non-stick cookware, cleaning/personal care products, food packaging, and other consumer products. They are now being found in pesticide products. Because of their ubiquitous use in many products, studies report that PFAS compounds are detectable in infants, children, and pregnant women. Furthermore, pregnant women can readily transfer compounds to the developing fetus through the placenta. Cardiovascular disease and diabetes are among the leading causes of death globally. Additionally, heart conditions are one leading cause of disability in the U.S., as research demonstrates environmental pollutant exposure can increase the risk of developing cardiovascular disease, including stroke, heart attack, heart failure, atrial fibrillation, and cardiac […]

(Beyond Pesticides, March 25, 2021) A new University of California San Francisco (UCSF) study, published in Environmental Science & Technology, finds over 100 chemicals present in U.S. pregnant women’s blood and umbilical cord samples. This discovery ignites concerns over prenatal exposure to chemicals from consumer and industrial products and sources. Furthermore, 89 percent of these chemical contaminants are unknown sources and uses, lacking adequate information, or are not previously detectable in humans. The National Health and Nutrition Examination Survey (NHANES) finds U.S. pregnant women experience frequent exposure to environmental pollutants that pose serious health risks to both mother and newborn. Many known environmental 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.  Current chemical biomonitoring methods only analyze a targeted few hundred chemicals—a small portion of the over 8000 chemicals the U.S. manufactures and imports. However, this study employs new technology that identifies a more comprehensive range of industrial chemicals. Therefore, research like this is essential for future technological development that can identify likely omnipresent chemical exposures for future health risks. UCSF scientists […]
