(Beyond Pesticides, April 28, 2020) Roughly a quarter of the global insect population has been wiped out since 1990, according to new research published in the journal Science. Billed as one of the most comprehensive assessments to date, the study finds significant overall insect declines, but notes of some specific bright spots. While variation in the ongoing crisis is to be expected, ultimately the trends in the data show the need for immediate policy and regulatory action to protect the insect world as the foundation of global food webs. The team of European scientists behind the research analyzed 166 studies spread out over 41 countries, and consisting of over 1,600 sites, with data beginning in the mid-1920s. Overall trends found declines in terrestrial insect biomass to be nearly 1% each year (~9% each decade). However, contrasting this data was a bright spot – freshwater insects were found to be increasing at an annual rate just over 1% (~11% each decade). The authors caution, however, that because fresh water covers only 2.4% of the earth’s surface, the increase may not be a good spatial representative of broader trends. While North America appeared to show more significant declines when compared to Europe, […]

(Beyond Pesticides, April 27, 2020) Federal guidance and orders by most Governors have identified “landscaping” as an essential activity that is permitted in spite of stay at home or shelter in place requirements. Tell Your Governor that Lawn Care Pesticides are Not Essential and Increase Risk of COVID-19. Most states follow some variation of guidance issued by the Department of Homeland Security, Memorandum on Identification of Essential Critical Infrastructure Workers During COVID-19 Response, in determining which industries are “essential” and can therefore remain in operation. DHS guidance identifies as essential, “Workers such as plumbers, electricians, exterminators, builders, contractors, HVAC Technicians, landscapers, and other service providers who provide services that are necessary to maintaining the safety, sanitation, and essential operation of residences, businesses and buildings such as hospitals, senior living facilities, any temporary construction required to support COVID-19 response.” While some of the services provided by landscapers and exterminators may be necessary to maintaining safety, sanitation, and essential operations, pesticide application for cosmetic lawn care purposes is not. The hazards of pesticides may be amplified during this pandemic. Threats to the immune and respiratory systems posed by pesticides are likely to make those exposed more susceptible to the coronavirus. Governors should designate as essential outdoor maintenance, including vegetation, only when necessary to […]

(Beyond Pesticides, April 24, 2020) The Centers for Disease Control and Prevent (CDC) has released a study showing a sharp increase—62% in some cases—in calls to poison hotlines about exposures to toxic household cleaners and disinfectants. This poisoning comes with the advent of the novel Coronavirus pandemic, as public health and government officials, and many media outlets have sensibly recommended that people regularly disinfect “high touch” surfaces and objects in their homes and other surroundings, but have not issued warnings on toxic effects nor the availability of lower toxicity or least-toxic products. Compliance with cleaning (sanitizers) and disinfection recommendations is an important public and personal health undertaking, but in this Covid-19 rigor lies a poison problem: the toxicity, as Beyond Pesticides has explained, of some cleaning and disinfecting products that are permitted by the Environmental Protection Agency (EPA) for sale and use. There are safer ways to disinfect those light switches, TV remotes, doorknobs, faucets, etc. First, a basic distinction between cleaning (also called sanitizing)and disinfecting: EPA offers definitions of the differences. “Cleaning is done with water, a cleaning product, and scrubbing. Cleaning does not kill bacteria, viruses, or fungi, which are generally referred to as ‘germs.’ Cleaning products are used […]

(Beyond Pesticides, April 23, 2020) Pesticide spray drift from adjacent farmlands expose butterfly larvae to lethal pesticide concentrations, according to research published in Environmental Toxicology and Chemistry by Iowa State University (ISU). Lack of previous experimental pesticide toxicity data makes it unclear as to what degree insecticides impact monarch butterfly (Danaus plexippus) productivity in milkweed (Asclepias spp.) habitats near pesticide-treated pasture. This study adds weight to the idea that pesticides are playing a role in the ongoing decline of this iconic butterfly, as researchers find insecticide drift from adjacent fields to be strongly associated with larval mortality. Future monarch butterfly conservation efforts should consider risks stemming from pesticide exposure when developing butterfly rehabilitation efforts, according to advocates. As co-author Niranjana Krishnan (ISU graduate student) states, “In order to make the best decisions about how and where to plant milkweed, we first need to find basic toxicity and exposure data.”  ISU researchers established monarch butterfly colonies by collecting larvae from roadside milkweeds, which they then reared in the laboratory for incubation. To analyze the relative toxicity of various insecticides on monarch butterflies, researchers applied normal field-application rates of each pesticide at different larval development stages. Scientists used a bioassay to measure the […]

In 1962, Rachel Carson said we stood at a crossroads: “The road we have long been traveling is deceptively easy, a smooth superhighway on which we progress with great speed, but at its end lies disaster. The other fork of the road — the one less traveled by — offers our last, our only chance to reach a destination that assures the preservation of the earth.” Eight years later, on April 22, 1970, the first Earth Day encouraged collective action for conservation. Now, in the midst of a pandemic and cascading environmental crises (arguably, down the road of disaster), forging a new path toward restoration will take courage and imagination. This Earth Day, Beyond Pesticides is putting forth a toolkit to abandon half measures and forge ahead with an organic approach for repairing human health and the environment. LISTEN TO SCIENCE Biodiversity is plummeting worldwide. The climate crisis looms even as COVID-19 grabs headlines. Environmental pollution is a predictor of coronavirus death. Never has it been more obvious that the global community is interconnected, and enforcing preventative measures is critical before it is too late. Meanwhile, the Trump Administration’s Environmental Protection Agency (EPA) ignores science, moving ahead with deregulation to […]

P-22 is being treated for mange; blood tests found anti-coagulant rodenticides, commonly known as rat poison. (Beyond Pesticides, April 21, 2020) Last week, the California Fish and Game Commission voted unanimously to give mountain lion populations in certain parts of the state temporary protective status, and initiate a year-long study to consider permanent safeguards. Mountain lions in California are under considerable threat from a range of issues, including inbreeding, human developments, and the use of hazardous rodenticides. “There’s an extraordinary urgency for action to preserve this population,” said Commissioner Samantha Murray prior to the unanimous vote, according to the OC Register. According to a study published last year in the journal Ecological Applications, mountain lion populations in Southern California’s Santa Ana and Santa Monica Mountains are at risk of local extinction within 50 years without intervention. Highways and other man-made structures have hemmed in the cougars, resulting in inbreeding that threatens genetic diversity and can result in sterile offspring.  Although specific actions under the new status are not guaranteed, it will force changes within California executive agencies. “For Caltrans, this could include building wildlife crossings over or under existing freeways or as part of freeway expansion projects,” J.P. Rose, staff […]

(Beyond Pesticides, April 20, 2020) As USDA takes public comments on its updated dietary guidelines, it important that sustainable, regenerative organic food production practices are an integral part. Since 1990, Congress has required an every-five-years review of its Dietary Guidelines — recommendations intended to promote public health and prevent chronic diseases. The next review and a draft updated version, the 2020–2025 Dietary Guidelines for Americans, is currently underway. USDA says that the dietary guidelines provide “information that helps Americans make healthy choices for themselves and their families.” In order to make healthy food choices, the guidelines must go beyond the traditional parameters to include how the food is produced. How food is produced affects the health of Americans not only as a result of the nutritional quality of the food, but also due to environmental contamination. Sign the petition to USDA and send a letter to Congress. Tell them that organic food must be emphasized in new dietary guidelines. Although research on the nutritional density of organic produce is equivocal, showing some higher levels of antioxidants, results are decidedly clear for animal products. Pastured organic animal products—including beef, lamb, pork, dairy, poultry, and eggs—have been shown to be superior to that of products of […]

(Beyond Pesticides, April 17, 2020) As the novel coronavirus pandemic upends much of human activity, some governments are acting to loosen environmental regulations — purportedly, in the interests of public health in the face of Covid-19 threats, and/or in deference to economic concerns of certain industrial sectors. There has been little analysis, to date, of what the “on the ground” impacts of these relaxed rules may be, but news out of Scotland illustrates some kinds of concerns critics and advocates have about such loosening of regulations. The Scottish Environment Protection Agency (SEPA) has issued new, temporary rules that allow some salmon farms both to ignore newly established limits on the amount of emamectin, an insecticide used to control sea lice that plague the salmon, and to boost use of azamethiphos, another insecticide used against the lice, beyond previous 24-hour limits. SEPA says the relaxed rules will endure only as long as the Covid-19 “lockdown” remains in place (perhaps the end of June), and apply only to new or expanding enterprises, which to date total approximately 14 of the country’s 200+ salmon farms. The farmed salmon industry represents a huge domestic and export commodity worth approximately $2.5 billion annually. In addition […]

(Beyond Pesticides, April 16, 2020) Pesticide exposure in farmland birds is a concomitant of pesticide-treated muesli (cereal) seed commonly planted during winter months, according to research published in Science of the Total Environment by United Kingdom (UK) scientists. Not only do pesticide-treated seeds pose the highest dietary risk to birds, but pesticide-treated seeds also go underreported as farmers often lack knowledge of what pesticides are on the seeds they plant. This study emphasizes the global effects of treated seeds, and their corresponding pesticide exposure, on bird species. Future risk assessments for bird should address these implications when implementing agricultural pesticide policies.  Farmers use of treated seeds exposes farmland birds to pesticides like neonicotinoids (neonics), including clothianidin (CLO). Pesticide residues then accumulate in the birds’ blood. UK scientists examined pesticides in farmland bird blood samples to connect the field-based use of treated seeds to clothianidin exposure patterns. At the time of this study, CLO was the most widely used pesticide on treated winter cereal seeds in the UK. Scientists recorded the presence of neonicotinoid-treated seed in 39 fields of 25 farms after seeding. Camera traps monitored farmland birds’ seed consumption. To measure CLO concentration in treated seed and seedling, scientists used liquid chromatography-tandem mass spectrometry to identify inorganic, organic, […]

(Beyond Pesticides, April 14, 2020) An op-ed in the New York Times asks, “What Happens if America’s 2.5 Million Farmworkers Get Sick?” Without those farmworkers, the year-round supply of fresh fruits and vegetables that we take for granted would be impossible. The supply chain of those vital foods starts with the workers who plant, cultivate, and harvest them. Our society and everyone living in the U.S. depend on farmworkers. Tell Congress to provide essential benefits to essential farmworkers. But farmworkers are at high risk from the coronavirus (COVID-19) pandemic. Living in crowded conditions, social distancing is impossible for them. They have little access to health care. Washing hands is often impossible in the field. With children home from school, they have additional childcare costs to pay with their low wages. They also have increased costs from using private transportation to avoid crowded buses. And many farmworkers are exposed to respiratory hazards like pesticides and fungal spores that make them more susceptible to the coronavirus. As the medical demand for personal protective equipment (PPE) increases, farmworkers are being faced with potential shortages of masks, gloves, and suits. Last month, a group of Washington farmworkers walked off a worksite because their employer was not offering sufficient […]

(Beyond Pesticides, April 13, 2020) Since 1990, Congress has required an every-five-years review of its Dietary Guidelines — recommendations that are supposed, minimally, to promote public health and prevent chronic diseases. The next review and a draft updated iteration, the 2020–2025 Dietary Guidelines for Americans, are currently underway. The Union of Concerned Scientists (and several colleagues) have examined recent studies on dietary patterns and sustainability; their analysis reveals that the current federal guidelines on diet are unlikely to support sustainability of the food system in the long-term. Beyond Pesticides concurs, and maintains that a transition to sustainable, organic, regenerative agriculture is the path to both improved human health and long-term sustainability of the natural world essential to life. The Union of Concerned Scientists’ (UCS’s) report — In Support of Sustainable Eating: Why U.S. Dietary Guidelines Should Prioritize Healthy People and a Healthy Planet — identifies this next version of the federal guidelines as a critical opportunity to shift the direction of the U.S. food and agricultural system toward far greater sustainability. UCS asserts that such a shift is beyond due: the food system in the U.S. has huge environmental impacts on pollution, use of chemical pesticides, biodiversity, and emissions that significantly […]

(Beyond Pesticides, April 9, 2020) Brazilian tax exemptions benefit the agrichemical industry to the tune of $2.2 billion USD annually, according to researchers from the Oswaldo Cruz foundation and the Federal Rural University of Rio de Janeiro. ABRASCO, the Brazilian Association of Collective Health, headed a new study which illuminates a tight relationship between Brazilian government and industry. Researchers additionally point to millions of dollars given from public resource funds to the companies. While industry lobby groups argue that toxic pesticides are necessary for development and food production, environmental and health advocates say the people of Brazil bear the brunt of toxic pesticide contamination while international companies profit. “It is as if you lived in a condominium and your neighbor didn’t have to pay the condominium fees. And that they got the pool dirty, and the shared gym space, generating costs for everyone else,” says Marcelo Novaes, a São Paulo State public defender who has spent years investigating this issue, “These benefits give large agribusiness companies a break while throwing the cost back on society.” By value, Brazil is the world’s largest consumer of toxic pesticides. Since President Jair Bolsonaro took office in 2018, the country has rapidly approved new […]

(Beyond Pesticides, April 8, 2020) We are deeply concerned about the impact of COVID-19 on organic farmers, farmworkers, businesses, certifiers and inspectors, and consumers. We are mindful of the need to protect the health and safety of all who are involved in organic agriculture, certification, and compliance. We also seek to advocate for responsible actions that will protect the integrity of the USDA organic seal during this difficult time. Send a message to USDA Secretary Sonny Perdue asking for support to organic farmers, farmworkers, businesses, certifiers and inspectors, and consumers. The recently enacted CARES Act includes a $9.5 billion emergency fund: “to prevent, prepare for, and respond to coronavirus by providing support for agricultural producers impacted by coronavirus, including producers of specialty crops, producers that supply local food systems, including farmers markets, restaurants, and schools, and livestock producers, including dairy producers.” It is critical that organic farmers and others in the organic community are included in the emergency response actions taken by USDA. Beyond Pesticides, as a member of the National Organic Coalition (NOC), is asking USDA Secretary Perdue to take action to support USDA organic through the coronavirus pandemic.  Please note, our form letter to Secretary Perdue is close to the […]

(Beyond Pesticides, April 6, 2020) The Trump administration’s U.S. Fish and Wildlife Service (USFWS) is moving forward with a proposal to grow genetically engineered crops (GECs) on National Wildlife Refuges in the Southeast United States, including 131 refuges in 10 states, Puerto Rico, and the U.S. Virgin Islands. Ask Congress to help stop the dangerous proposal to allow genetically engineered crops on National Wildlife Refuges in the southeast United States. The proposal is the subject of a draft environmental assessment and opens the door to escalating uses of GE crops and harmful pesticides in wildlife refuges. In 2014, public pressure and lawsuits by environmental groups led to the Obama administration’s decision to phase out GE crops and ban neonicotinoid insecticide use on national wildlife refuges. On August 2, 2018, the Trump administration’s USFWS issued a memorandum that reversed the prohibition. The reversal allows the refuge system to make decisions on the use of GECs and neonics on a case-by-case basis in compliance with the National Environmental Policy Act (NEPA), which is also under attack by the Trump administration. The Center for Biological Diversity, Center for Food Safety, and others quickly challenged the 2018 reversal memorandum with a lawsuit. National Wildlife Refuges are federal public lands specifically designated to […]

(Beyond Pesticides, April 3, 2020) In mid-March, the Environmental Protection Agency (EPA) rolled out new rules for “biological evaluations” — assessments of pesticide risks to endangered plant and animal species that are supposed to be protected under the Endangered Species Act (ESA). The agency’s press release announcing the change is misleadingly titled: “Trump Administration Takes Major Step to Improve Implementation of the Endangered Species Act.” But as the Center for Biological Diversity (CBD) reports, the “revised methods for assessing pesticide risks . . . will allow widespread harm to most of the nation’s most endangered plants and animals.” Beyond Pesticides reviewed the status of pesticide threats to endangered species in November 2019 and provides ongoing coverage of the issue. ESA requires EPA to conduct biological evaluations (BEs) of pesticides to assess their impacts on listed (endangered and threatened) species and their critical habitats. EPA’s new “Revised Method” ignores many of the ways that protected species are commonly hurt or killed by pesticides, and allows the continued marketing and use of pesticides without sensible constraints that would protect those species. CBD cites two examples of ignored impacts: downstream impacts of pesticide runoff into waterways from treated farmland, and the loss of […]

(Beyond Pesticides, April 2, 2020) As COVID-19 grips the U.S. and medical workers scramble for personal protective equipment (PPE), farmworkers charged with applying pesticides are facing potential shortages of the same protective masks, gloves, and Tyvek suits. Farmworkers are a frontline community to the compounding crises of pesticide poisoning and the coronavirus pandemic. PPE producers announced plans to increase production of masks and other gear, but orders for disposable respirators and masks may take over three months to arrive to agricultural suppliers. “All of our major suppliers is being impacted,” said Carl Atwell, an agricultural PPE provider in Wisconsin, “Whether it’s Dupont, 3M, Honeywell—they’re all being told by the government to divert supply to hospitals first.” Worsening the dilemma, common toxic pesticides are respiratory irritants that put farmworkers at higher risk. Epidemiological studies of farmworkers link toxic pesticide exposure with asthma or asthmatic symptoms. Individuals with underlying respiratory issues are less likely to recover from COVID-19. “This issue of workers being exposed to toxic chemicals was already a big problem before the pandemic, so I can only imagine what will happen now,” Iris Figueora, a staff attorney with Farmworker Justice, told Bloomberg Environment. Just last month, a group of Washington […]

(Beyond Pesticides, April 1, 2020) Your comments are due by Friday, April 3, end of day. The National Organic Standards Board (NOSB) meets April 29-30 online to debate issues concerning what goes into your organic food. Lend your voice to continuous improvement by learning about issues and submitting comments. From the very beginning, with the passage of the Organic Foods Production Act in 1990, “organic” has meant “continuous improvement.” The primary mechanism for continuous improvement in organic production is the high level of public involvement that comes from twice-annual meetings of the stakeholder board. The second mechanism is the sunset process, which helps move synthetic substances out of organic production as the market invests in growing organic inputs and ingredients. Despite USDA’s efforts to weaken the sunset process, the 5-year cycle of review of every synthetic substance currently used in organic production and processing, offers us an opportunity to keep organic strong and strengthen any weaknesses. Items on the NOSB agenda in April include materials allowed in organic production, as well as discussion of policies and sunset materials on which the NOSB will vote in the Fall. We have identified some priority issues of both kinds. The only voting issue on […]

(Beyond Pesticides, March 31, 2020) Adding to the widespread and problematic use of neonicotinoid pesticides as seed treatments, a recent study published in BioScience finds that there are significant knowledge gaps among some farmers about the seeds they are planting. The research indicates that those gaps contribute to underreporting of accurate data on the use of pesticide-coated (often with neonicotinoid pesticides) seeds — because farmers may not know what pesticides are on the seeds they plant. Pennsylvania State University reports on the study, in Phys.org, saying, “This lack of data may complicate efforts to evaluate the value of different pest management strategies, while also protecting human health and the environment.” Beyond Pesticides advocates for widespread adoption of organic, regenerative systems and practices that precludes the use of such pesticides.  The research was conducted by a team of scientist from around the U.S., led by Claudia Hitaj, PhD, of the Luxembourg Institute of Science and Technology, and former economist at USDA’s Economic Research Service. In the Phys.org coverage of the study, assistant professor of epidemiology and crop pathology at Penn State, Paul Esker, PhD, notes that this lack of farmer knowledge can lead to overuse of pesticides, which would increase the already considerable risks […]

NOTICE: Beyond Pesticides urges Governors to stop the use of lawn pesticides during the COVID-19 crisis because the toxic chemicals used are typically immune and respiratory system toxicants, elevating key risk factors for those vulnerable to coronavirus hazards. Contact your Governor to classify chemical lawn care as non-essential. (Beyond Pesticides, March 30, 2020) Last week, Beyond Pesticides sued TruGreen, the national chemical landscaping company, for misrepresenting the safety of the toxic chemicals that it uses to treat lawns. The case is Beyond Pesticides v. TruGreen (DC Superior Court, Case No. 2020CA001973B, March, 20, 2020). At the same time, the organization is urging all states to prohibit toxic chemical spraying in neighborhoods as non-essential and hazardous. Widespread exposure to lawn pesticides, which are immune system and respiratory toxicants, can elevate serious risk factors associated with COVID-19 (coronavirus). As part of its marketing, TruGreen tells consumers that it offers environmentally friendly, sustainable lawn care services that use no chemicals that may cause cancer, allergic reactions, or other health or environmental harms. These claims, according to Beyond Pesticides’ complaint, are false and deceptive and illegal under the laws of the District of Columbia. Advocates suggest that during the COVID-19 crisis the cessation of […]

(Beyond Pesticides, March 27, 2020) Faced with the COVID-19 (coronavirus) threat, there is tremendous pressure to use toxic disinfectants, despite the availability of safer products. In fact, while the Centers for Disease Control and Prevention (CDC) is recommending 70% alcohol for surface disinfection, the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs is advising the use of unnecessarily toxic substances, and reducing standards that govern their allowance on the market. EPA’s pesticide program allowed 70 new disinfectants yesterday, at the same time that the agency overall announced that it is waiving enforcement of environmental standards during the coronavirus outbreak—a devastating blow to public health and environmental protection. Beyond Pesticides, in its factsheet, Protecting Yourself from COVID-19 (coronavirus) without Toxic Sanitizers and Disinfectants, says, “Fight the coronavirus with common sense prevention and safer disinfection products. Avoid products that increase vulnerability to respiratory problems.” (See the factsheet below.) To some extent, the expanded allowance of disinfection products on top of the 281 disinfectants previously permitted has been made possible by relaxing oversight on so-called “inert” or other ingredients that are not disclosed on product labels and often highly toxic. The agency says it is allowing the use of these “inerts” with “no […]

(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, March 25, 2020) The Trump administration’s U.S. Fish and Wildlife Service (USFWS) is moving forward with a proposal to grow genetically engineered crops (GECs) on national wildlife refuges in the Southeast United States. The draft environmental assessment allows wildlife to consume pesticide-laden produce, considers chemical-intensive genetically engineered crops no less damaging to the environment than “non-use of GECs,” and permits and escalation of climate change with toxic pesticide use increases. USFW’s proposal fails to mention the success of organic agriculture and consider it as one of the alternative management strategies. The proposal is up for public comment until April 10, 2020. In 2014, public pressure and lawsuits by environmental groups led to the Obama administration’s decision to phase out GE crops and ban neonicotinoid insecticide use on national wildlife refuges. On August 2, 2018, the Trump administration’s USFWS issued a memorandum that reversed the prohibition. The reversal allows the refuge system to make decisions on the use of GECs and neonics on a case-by-case basis in compliance with the National Environmental Policy Act (NEPA), which is also under attack by the Trump administration. The Center for Biological Diversity, Center for Food Safety, and others quickly challenged the 2018 […]

(Beyond Pesticides, March 24, 2020) Last week, Maryland became the latest state to prohibit use of the brain-damaging insecticide chlorpyrifos, after a measure cleared both the state Senate and House. Although the legislation implements a limited ban that sunsets after four years, advocates consider this action a step in the right direction that will protect the health and safety of Maryland residents. “Even amidst our current public health crisis, the Maryland legislature acted to protect all Marylanders’ health for years to come by banning this toxic pesticide, and we are so grateful,” said Ruth Berlin, Executive Director of the Maryland Pesticide Education Network to WBOC. Chlorpyrifos is an organophosphate insecticide known to inhibit the proper nerve functioning by affecting the enzyme acetylcholine esterase. The impacts of this pesticide are particularly concerning for young children, as research finds that children exposed to high levels of chlorpyrifos had mental development delays, attention problems, attention-deficit/hyperactivity disorder problems, and pervasive developmental disorder problems at three years of age. While Maryland is the fourth state to restrict the use of chlorpyrifos, it is the second to implement these restrictions through legislation. In California, the state Department of Pesticide Regulation is implementing a phase out of […]
