(Beyond Pesticides, October 3, 2024) The American Academy of Pediatrics published a technical report in September on antimicrobial resistance, which it calls a global public health threat, identifying the health implications of antibiotic use in animal agriculture. The lead authors, both medical doctors from the Department of Pediatrics at Vanderbilt University Medical Center, note the rise in antimicrobial-resistant infections that result in increased morbidity, mortality, and health care costs for not only adults, but infants and children as well. “[A]ll use of antimicrobial agents exerts selective pressure that increases the risk of development of resistance,” the authors state, highlighting the importance of limiting antimicrobial uses. “Antimicrobial resistance is an organism’s ability to survive exposure to an antimicrobial agent that was previously an effective treatment. Resistance traits can be acquired either through new mutations or through transfer of genetic material between organisms,” the authors report. Antimicrobial-resistant pathogens, such as bacteria and viruses, can be transmitted “through the food supply, direct contact with animals, environmental pathways, and contact with infected or colonized humans,” they continue. Use of antimicrobial agents, especially over extended periods of time or with repeated exposure, can cause resistance to not only that agent, but to multiple agents. As […]

(Beyond Pesticides, September 17, 2024) Today, International Microorganism Day, is a prime moment to focus on the complexity of billions of living beings that establish the foundation of land management and food production. Organic advocates, community members, and farmers identify the protection and enhancement of biological diversity in the soil as a key goal, especially in light of mounting concerns over rising microbial resistance to chemical-intensive practices. A recent article in British Journal of Environmental Sciences points to several microbial populations adversely affected by pesticide-contaminated soil on various farmland plots in Nigeria. There are significant variations in bacteria presence between pesticide-treated and control plots, with a lab analysis finding “[s]eventy-five percent (75%) of pesticide residue was detected in the soil samples,” which includes paraquat dichloride, endosulfan, diazinon, and N-(phosponomethyl)glycine [glyphosate]. This report builds on years of research from higher education institutions worldwide, including participatory research centering applied experiments on farmland, demonstrating the consequences of relying on pesticide-intensive agriculture and land management. The main goal of this report is to “determine the influence of pesticide contamination on the microbial population, physiochemical parameters and pesticide residue of soil of selected farmlands in Otuoke, Bayelsa State, Nigeria.” Researchers document the presence of eleven […]

(Beyond Pesticides, January 11, 2024) In a move to safeguard public and animal health, the U.S. Food and Drug Administration (FDA) warned nine manufacturers and distributors in December last year to stop selling unapproved and misbranded antimicrobial animal drugs, with the director of FDA’s Center for Veterinary Medicine, Tracey Forfa, explaining to the public that “inappropriate use of medically important antimicrobials contributes to the development of antimicrobial resistance, which affects both human and animal health.”  This action and announcement exhibit a higher degree of concern about antimicrobial resistance—understood as a growing worldwide pandemic—than the history and ongoing inaction by the U.S. Environmental Protection Agency (EPA)—resulting in the allowance of widespread nonmedical uses of antibiotics in agriculture and on synthetic (or artificial) turf. Contrary to broad scientific understanding, EPA told a federal appeals court last year that, “There is no data that antibiotic use in agriculture leads to the presence of antibiotic resistance in bacteria of human health concern,” and that “[a]t the present time, there is little evidence for or against the presence of microbes of human health concern in the plant agricultural environment.” The issue of resistance discussed in the scientific literature concerns reduced susceptibility to clinically important antimicrobials, […]

(Beyond Pesticides, November 1, 2023) As communities consider maintenance and renovation of their playing fields, it is not uncommon for synthetic (or artificial) turf to come up as an alternative to natural grass. Promoters of synthetic turf argue that it provides a solution to climate change, reduces water use and maintenance costs, and allows for year-round play. But is this true? Is synthetic turf an environmentally responsible alternative to its organic grass counterpart? An established and growing body of scientific evidence is demonstrating environmental and health risks with synthetic turf. In addition, there is growing concern for the safety of those playing on artificial grass, which has led to a call from the National Football League’s (NFL) Players Association to utilize natural grass on all 30 NFL stadiums after New York Jets quarterback Aaron Rodgers suffered a season-ending Achilles tear in September and Kansas City Chiefs tight end Travis Kelce’s mid-game ankle injury. Synthetic turf playing fields are reliant on polluting plastic (can contain perfluoroalkyl and polyfluoroalkyl substances-PFAS) and toxic pesticides for managing bacteria, mold and fungus, create contaminated water runoff, and cover over the natural environment, which is critical to preserving health and biodiversity, and averting climate disasters. Artificial […]

(Beyond Pesticides, January 25, 2022) Research at the University of North Carolina at Chapel Hill identifies how triclosan (TCS), an antimicrobial agent used in many household products, impacts the microbial communities in the gut, causing inflammation. According to the study published in Nature Communications, triclosan worsens the effects of ulcerative colitis, an inflammatory bowel disease (IBD), through the retention of harmful bacteria. Ample evidence demonstrates environmental contaminants, including pesticides like triclosan, negatively affect microbes in the human mouth and gut. Although studies show how triclosan exposure affects human health, more research is now questioning how exposure to these toxic chemical influences gut health. Therefore, studies like these highlight the importance of evaluating how chemical contaminant deregulates normal bodily function through microbiome changes. Furthermore, the study has significant implications for considerations that should be, but are not currently, a part of pesticide review and registration by the U.S. Environmental Protection Agency (EPA). The researchers note, “Together, our results define a mechanism by which intestinal microbes contribute to the metabolic activation and gut toxicity of TCS, and highlight the importance of considering the contributions of the gut microbiota in evaluating the toxic potential of environmental chemicals.” Instances of intestinal bowel disease (IBD)—involving the chronic inflammation […]

(Beyond Pesticides, December 13, 2021) If you plan to give socks, sweatshirts, or other items of clothing as holiday gifts, you need to be aware that many such items are treated with toxic chemicals. Such treated items may be labeled as “odor free” and may contain nanosilver, triclosan (banned in soaps, but allowed in textile and household products), or other (undisclosed) chemicals hiding behind brand names such as Microban® or FreshIQ. Since it is not always possible to determine which chemical may be used in these textiles, the best option is to buy clothing that is organic or made locally.  The Environmental Protection Agency (EPA) exempts treated articles from registration requirements under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Although the chemicals themselves may be registered antimicrobial pesticides, the treated products in which they are found—and which expose the public to them—are not considered pesticides. Besides clothing treated with antimicrobials to control odors, EPA also allows seeds, wood, paints, cutting boards, sponges, mops, and even toothbrushes to be treated with antimicrobial pesticides under the exemption—as long as claims made for the treatment only pertain to protecting the treated article. For example, sock manufacturers may claim that the treated socks […]

(Beyond Pesticides, November 23, 2021) The U.S. Environmental Protection Agency (EPA) announced, in mid-October, a revision of its guidance on the evaluation of antimicrobial pesticides used against Candida auris (C. auris). This pathogen is a type of fungus (a yeast) that can cause serious infection, and can spread readily among patients and staff in hospitals and other congregate healthcare settings (such as nursing homes). C. auris has developed resistance to what used to be the therapeutic impacts of major antifungal medications. (Resistance is a major and growing problem in healthcare and in agriculture, with the latter exacerbating the former.) Another moving part in this unholy development of “chemical compounds no longer working” is EPA’s failure to assess the efficacy of any pesticides that are not used for public health purposes; for example, EPA evaluates the efficacy of only those antimicrobial compounds whose use patterns classify them as human-health-related. This failure to evaluate efficacy of all other pesticide products leaves many people in the dark about whether what they may be using actually works — never mind the potential risks associated with that use. The antifungal medications that have been used for many years to treat Candida infections often no longer work for C. auris; […]

(Beyond Pesticides, October 16, 2020) The Lancet has published an article that identifies several of the multiple and interacting crises the U.S. and world face, with a focus on another “looming potential pandemic . . . [a] rise in multidrug-resistant bacterial infections that are undetected, undiagnosed, and increasingly untreatable, [whose rise] threatens the health of people in the USA and globally.” It calls on leaders in the U.S. and beyond, asking that even as they address the current coronavirus pandemic, they also attend to the antimicrobial resistance (AMR) problem, which is a growing threat to public health. The co-authors outline a number of strategies for progress on AMR, including banning of medically important antibiotics in agribusiness, and promoting consumer, and supplier and private sector, awareness and action on food choices. Beyond Pesticides endorses these strategies, but insists that a genuine solution would include the transition to organic agriculture, not least for the health benefits it would provide. The introduction to the article adds another crisis layer — the climate emergency — and asserts that any resolutions of these crises will, or will not, unfold in a political context: “The outcome of the U.S. election will have far-reaching consequences for planetary […]

(Beyond Pesticides, March 26, 2020) An Environmental Protection Agency (EPA) determination could allow toxic antimicrobial nanosilver to be registered for use in textiles, including clothing, according to Bloomberg Environment. Nanotechnology products harm human, environmental, and animal health. Despite this, EPA’s preliminary conclusion approves the registration of nanosilver-containing Polyguard as a textile “protectant.”  Public challenges have blocked nanosilver registration in the past when courts found EPA lacks the authority to register these toxic particles. “They’ve failed to collect data about potential exposure routes for nanosilver products, including textiles, which toddlers or pets could chew or put in their mouths,” says Jaydee Hanson, policy director at the Center for Food Safety. “Another challenge is how do you accurately test the actual product and what data do you have which suggests that other kinds of nanosilver work the same way?”  Nanosilver, or silver nanoparticles, are microscopic particles that are used as antimicrobials, which kill bacteria and fungi. They range in size from 1-100 nanometers (nm) across or 0.1% the diameter of a human hair.  Some research attributes nanosilver toxicity impacts to its small size, which allows it to be absorbed through the skin and enter the bloodstream and lymphatic system to disrupt normal organ function. The […]

(Beyond Pesticides, July 3, 2019) A disturbing association between urinary triclosan concentrations and osteoporosis has been identified in an epidemiological study. Drawing from the National Health and Nutrition Examination Survey (NHANES) results for 1,848 U.S. adult women, the authors conclude that higher concentrations of urinary triclosan are associated with lower bone mass density and higher prevalence of osteoporosis among U.S. adult women. The study, published in the Journal of Clinical Endocrinology and Metabolism, adds weight to previous laboratory results, which showed that endocrine-disrupting chemicals such as triclosan can interfere with bone metabolism. Triclosan and its byproducts are known endocrine disruptors and have been shown in laboratory studies to interfere with collagen and bone structure. Taken together with previous findings, the new epidemiological results demonstrate that the ubiquitous endocrine disruptor triclosan “could lead to lower BMD [benchmark dose] and increased prevalence of osteoporosis in U.S. adult women.” Triclosan is used as an antimicrobial agent in products regulated by both the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA), and cumulative exposure to triclosan registered by both agencies pose unacceptable risks to human health and the environment. Triclosan exposure has become so common that it has shown up in […]

(Beyond Pesticides, January 10, 2019) The Trump administration is opening the floodgates to allow widespread use of antibiotics in citrus (grapefruits, oranges and tangerines) production, expanding on an emergency use decision it made in 2017. The public has an opportunity to comment on the widespread use of streptomycin by January 19, 2019. You can comment on the federal government’s public comment page (regulations.gov) by leaving a comment opposing any additional use of antibiotics in food production during a national and international crisis of deadly disease resistance to antibiotics. You can copy Beyond Pesticides’ prepared comment below and add your own concerns. Strikingly, the decision allows for up to 480,000 acres of citrus trees in Florida to be treated with more than 650,000 pounds of streptomycin per year, and 23,000 citrus acres in California will likely be treated annually. The two approved antibacterial chemicals to be used as a pesticide in citrus production are streptomycin and oxytetracycline. These uses were permitted by the U.S. Environmental Protection Agency (EPA) under an emergency exemption in May, 2017, allowing residues of antibiotics in Florida orange juice, for the antibiotics streptomycin and oxytetracycline –allowing their use for a bacterial disease, citrus greening (Candidatus Liberibacter asiaticus (CLas) bacterium that causes Huanglongbing), […]

(Beyond Pesticides, January 2, 2019) The “indoor microbiome” of yoga studios and other athletic facilities often contain significant levels of antibacterial chemicals like triclosan, which show up in dust and breed antibiotic resistance, according to research published last month in the journal mSystems. Triclosan may be banned from hand soaps, but its continued use in a myriad of other products, from disinfectant sprays to impregnated clothing, yoga mats, and other work-out equipment makes it difficult to avoid this now-ubiquitous chemical. This is a public health concern because these antibacterial or antimicrobial chemicals are link to antibiotic-resistant bacteria. Antibiotic resistance kills over 23,000 people each year, according to the Centers for Disease Control and Prevention (CDC). In addition to the CDC, the World Health Organization has cited this escalating problem as become one of the biggest public health challenges of our time. Many people may suspect their gym or yoga study is not a germ-free location, but attempts to address these germs through antibacterial sprays or impregnated yoga mats and other surfaces, may be exacerbating the issue—doing much more harm than good. The continued detection of triclosan and its impacts at new and unexpected locations are feeding renewed calls for a complete ban on […]

(Beyond Pesticides, September 17, 2018) The Fall 2018 NOSB meeting dates have been announced and public comments are due by October 4, 2018. Your comments and participation are critical to the integrity of the organic label. Written comments may be submitted through Regulations.gov  until 11:59 pm ET October 4, 2018. Reservations for in-person and webinar comments close at the same time. The proposals of the National Organic Standards Board (NOSB), as a part of its ongoing review of practices and materials, are published for public comment. On our Keeping Organic Strong page, Beyond Pesticides will be providing the public with a listing and analysis of the issues under consideration of the Board when it meets in Saint Paul, MN on October 24 – 26, 2018. You can view USDA’s announcement of the NOSB’s meeting and proposals here. Issues before the NOSB include materials allowed in organic production as well as some policy issues. Materials are either the subject of petitions or the subject of sunset review (concerning whether to be allowed for another 5 years). To be allowed, materials must have evidence summarized in the proposals that they meet the OFPA requirements of essentiality, no adverse effects on humans and the […]

(Beyond Pesticides, March 29, 2018) Rising use of antibacterials like nanosilver in textiles and other consumer goods is leading scientists to consider methods to filter out these materials before they pollute the environment. As detailed by research published in Sustainable Chemistry and Engineering, experts at University of Massachusetts, Dartmouth, are developing a process to filter out these toxic materials from our washing machines. While preventing downstream waste is laudable, it misses the fundamental question whether nanosilver and other antibacterials need to be added to consumer clothing in the first place. Nanosilver is antimicrobial nanoparticle (typically defined as a particle between 1-100 nanometers) regulated as a pesticide that is added to consumer goods such as textiles, cosmetics, disinfectants, toys and other household items in attempts to kill bacteria or reduce odor. See the Project on Emerging Nanotechnologies for an extensive listing of products containing nanoparticles on the market. Nanosilver, which makes up roughly 25% of nanomaterials used in the consumer market, is a particularly concerning nanoparticle given past research on its risks to health and the environment. Studies have found that, when impregnated into textiles like sportswear, nanosilver does not just wash out in the washing machine, it can also seep […]

(Beyond Pesticides, January 26, 2018) Triclosan may be on its way out in soaps and disinfectants, but its presence on toothbrushes could stick around for a long time, according to research published in Environmental Science and Technology by a group of scientists from University of Massachusetts, Amherst (UMass Amherst). The Food and Drug Administration (FDA) banned the use of over the counter triclosan-containing soap in 2016, and late last year extended the ban to include health care and hospital settings, but the toxic antibacterial can still be found in toothpaste and other consumer products. Many may have have checked their toothpaste label and switched to a non-triclosan toothpaste after the recent news, but scientists say that exposure to this persistent chemical may continue through toothbrushes, if triclosan toothpaste was previously used. To test triclosan absorption while brushing, researchers purchased 22 different toothbrushes, each with different components, from bristles only, to those with polishing cups, gum protectors, or tongue cleaners. Different toothpastes, including six with and 15 without triclosan, were also used.  A mixture used to imitate saliva was added to toothpaste and put into a vial that was then brushed with different toothbrushes over a 3 month period – the […]

(Beyond Pesticides, January 22, 2018) The organophosphate pesticides chlorpyrifos, malathion, and diazinon are likely to jeopardize the continued existence of endangered species and adversely modify their critical habitats, according to the newly released report from the National Marine Fisheries Service (NMFS). By law, the Environmental Protection Agency (EPA) must not allow their use. Tell EPA to ban chlorpyrifos, malathion, and diazinon unless it can restrict uses to protect endangered species. Under Section 7 of the Endangered Species Act (ESA), any agency action requires a finding that the action “is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat.” The December 31, 2017 Biological Opinion from NMFS followed an ecological assessment that relied upon multiple lines of evidence to determine effects on species and their designated habitats. These impacts include: • “the direct and indirect toxicity of each chemical to aquatic taxa groups (e.g., fish, mammals, invertebrates); • specific chemical characteristics of each pesticide (e.g., degradation rates, bioaccumulation rates, sorption affinities, etc.); • expected environmental concentrations calculated for generic aquatic habitats • authorized pesticide product labels; • maps showing the spatial overlap of listed species’ habitats with […]

(Beyond Pesticides, July 12, 2017) In a move that threatens to further the spread of antibiotic resistance, researchers at the University of Western Australia (UWA) mining a collection of antimalarial drugs for potential new herbicides. Joshua Mylne, PhD, a senior lecturer in the School of Molecular Sciences (SMS) who directs the project, got started based on work he did while in the Australian Army Reserve. There he discovered that “malarial parasites are actually closely related to plants.” Due to widespread resistance of weeds to the popular herbicide glyphosate, Dr. Mylne began investigating antimalarial drugs as potential replacements. Malaria parasites are actually protozoans in the genus Plasmodium. Their crucial connection with plants is that the parasite contains a plastid similar to the chloroplast in plants. Like the chloroplast in plants, this plastid is critical for the survival of the parasite. Along with organic chemist Keith Stubbs, PhD, associate professor in SMS, Dr. Mylne began screening chemicals in the “Malaria Box,” an open source collection of potential anti-malarial drugs that have never been commercialized. Of the 20 chemicals tested on the small weed Arabidopsis thaliana, 11 were found to have some herbicidal activity. They were then compared to the herbicides glyphosate, glufosinate, asulam, […]

(Beyond Pesticides, June 21, 2017) More than 200 international scientists and medical professionals have signed the Florence Statement on Triclosan and Triclocarban, which states that triclosan and its chemical cousin triclocarban pose a risk to human health, and urges the international community to limit use of these antimicrobials, which are associated with bacterial resistance and no more effective than soap and water. In 2016 after manufacturers failed to prove efficacy, the U.S. Food and Drug Administration (FDA), which regulates cosmetic triclosan products, announced that manufacturers must, by September 2017, remove triclosan from over the counter hand soaps. The agency still allows the chemical in toothpastes and other products, such as hand wipes. The Environmental Protection Agency (EPA), which regulates triclosan in household items, textiles and plastics, still permits wide use of the chemical in a range of products. The Florence Statement on Triclosan and Triclocarban is “based on extensive peer-reviewed research,” and “concludes that triclosan and triclocarban are environmentally persistent endocrine disruptors that bioaccumulate in and are toxic to aquatic and other organisms.” The statement includes evidence of human health threats, and provides recommendations intended to mitigate harm from triclosan, triclocarban, and other similar antimicrobials. The recommendations are listed below: “Avoid […]

(Beyond Pesticides, June 6, 2017) Last week, the U .S. Court of Appeals for the Ninth Circuit concluded that the U.S. Environmental Protection Agency (EPA) failed to show that its conditional registration of the antimicrobial, nano-silver pesticide product “NSPW-L30SS” (previously “Nanosilva”) is in the public interest and revoked its registration. The case, brought by the Natural Resources Defense Council (NRDC) and the Center for Food Safety (CFS), challenged the approval of the novel nanotechnology which was marketed for use in an unknown number of textiles and plastics. The decision underscores the need for EPA to ensure pesticide products, including nanomaterials, meet the standards of federal pesticide law. According to the Center for Food Safety, the Court’s decision is the first of its kind to address EPA’s responsibilities in issuing conditional registrations of new pesticide products like NSPW-L30SS. In its ruling, the Court ruled that EPA had failed to show that “conditional approval” of NSPW-L30SS as a new pesticide supported a public interest finding by the EPA with substantial evidence. EPA had conditionally registered the controversial pesticide back in 2015. Under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA can only conditionally register new active ingredients, such nanosilver particles, if EPA […]

(Beyond Pesticides, June 2, 2017) According to a new study, levels of triclosan spike in the bodies of children after they brush their teeth or wash their hands. Triclosan, a controversial antimicrobial, is frequently added to consumer care products. Last year, the Food and Drug Administration (FDA) banned the use of triclosan in hand soaps, but it is still allowed in toothpaste and numerous plastic and textile products regulated by the U.S. Environmental Protection Agency (EPA). Many companies had previously decided, due to consumer pressure, to remove triclosan from hand soaps years ahead of the FDA decision. Researchers collected and tested the urine of 389 mothers and their children –three times during pregnancy, and then took between 1-6 samples from children between the ages of 1 and 8 years old. The researchers found triclosan in over 70% of samples taken. In the group of 8 year olds, they report that levels were 66% higher in the children that used hand soap. For those that wash their hands over five times a day, the levels increase more than four times in comparison to children who wash their hands once or less per day. For toothpaste, researchers find that children who had […]

(Beyond Pesticides, May 23, 2017) Health ministers from the G20 nations, the largest advanced and emerging economies, identified Antimicrobial Resistance (AMR) as a “current and increasing threat and challenge to global health” and committed the member countries to several actions aimed at reducing the occurrence of AMR. The outcome of the first meeting of G20 health ministers, the Berlin Declaration of the G20 Health Ministers, addresses a wide range of global health issues, including AMR. The G20 declaration contains little more than a mention of antimicrobials in agriculture, but both it and the G20 Agriculture Ministers’ Declaration support WHO’s Global Action Plan on Antimicrobial Resistance. WHO’s action plan includes measures of effectiveness of actions, including member state adoption of “policies on use of antimicrobial agents in terrestrial and aquatic animals and agriculture, including: implementation of Codex Alimentarius and OIE [Organization for Animal Health] international standards and guidelines as well as WHO/OIE guidance on the use of critically important antibiotics; phasing out of use of antibiotics for animal growth promotion and crop protection in the absence of risk analysis; and reduction in nontherapeutic use of antimicrobial medicines in animal health.” The G20 meeting last weekend was not the first time world […]

(Beyond Pesticides, March 20, 2017) Last week, the Environmental Protection Agency (EPA) announced it is allowing residues of antibiotics in Florida orange juice, after approving an emergency exemption for the antibiotics streptomycin and oxytetracycline –allowing their use for a bacterial disease, citrus greening (Candidatus Liberibacter asiaticus (CLas) bacterium that causes Huanglongbing), in Florida citrus crops through December of 2019, and further exacerbating bacterial resistance. The World Health Organization has called bacterial resistance “one of the biggest threats to global health, food security, and development today.” The agency announced March 15, “EPA is issuing these tolerances without notice and opportunity for public comment as provided in FFDCA section 408(l)(6).” EPA states “time-limited tolerances are established for residues of streptomycin in or on fruit, citrus, group 10-10, at 2 ppm, and the dried pulp of these commodities at 6 ppm.” For oxytetracycline, EPA is allowing residues ” in or on all commodities of fruit, citrus, group 10-10, at 0.4 ppm.” [See below; organic standards do not allow antibiotic use.] In its review, EPA has determined that the toxicological endpoints of dietary exposure under the allowed tolerances meet the safety standard of the Federal Food, Drug and Cosmetic Act, but does not consider the public health impact of bacterial resistance to […]

(Beyond Pesticides, March 9, 2017) A recent European Parliament (EP) report concludes that organic agriculture and food offer clear human health benefits over chemical-intensive agriculture. The report, Human health implications of organic food and organic agriculture, which was written by scientists from universities across Europe, used existing scientific literature to assess the human health effects from organic agricultural systems. The authors determined that organic agriculture has considerable benefits, including reduction in antibiotic resistance, lowered levels of cadmium in organic crops, and decreased dietary pesticide exposure levels. According to the EP report, “Overall, consumption of organic food substantially decreases the consumer’s dietary pesticide exposure, as well as acute and chronic risks from such exposure.” Organic farming is a systems approach that values healthy, biologically active soils to support plant life and provide critical environmental benefits, such as improved water infiltration, pest suppression, and carbon storage. It is through this preventive, systems approach that organic agriculture eliminates the necessity for pesticides, and instead relies upon soil health to prevent the problems that chemical-intensive agriculture cannot. This report adds to the growing body of evidence on impaired learning and lowered IQs in children prenatally exposed to low levels of certain pesticides, such as organophosphates. The […]
