(Beyond Pesticides, December 3, 2015) Last month, the European Commission and member states approved the new pesticide flupyradifurone. The department, known as Directorate-General for Health and Food Safety, authorized the approval of the pesticide, which is an insecticide in  the chemical class  butenolides. Bayer Crop Sciences, the creator of flupyradifurone, touts the insecticide as a “safe” alternative to neonicotinoids (neonics), although both neonics and butenolides are systemic, persistent, and acutely toxic to adult honey bees. Already launched in the United States, Mexico, Nicaragua, Guatemala, Honduras, and the Dominican Republic, advocates are pointing to the hasty nature of flupyradifurone’s approval and the lack of scientific research supporting its use. Flupyradifurone, marketed as “Sivanto prime” in Europe, is approved for use in the EU on sucking pests that feed on fruits and vegetables as well as specialty crops such as hops.  It is also approved for use in seed coatings. The chemical is neurotoxic and can inhibit nicotinic acetylcholine receptors (nAChR) in the nervous system. Neonicotinoids, widely  criticized for their harmful effects on bees,  affect the nervous system in the same way. Matthias Haas, Ph.D., Global Project Manager at Bayer CropScience says, “It combines efficacy and convenience for the grower with excellent […]

(Beyond Pesticides, December 1, 2015) Last month, the U.S. Food and Drug Administration (FDA) approved, without a labeling requirement, a genetically engineered (GE) salmon designed to grow faster and come to market quicker than other farmed salmon. The fish, dubbed AquAdvantage by its developer, Massachusetts-based biotechnology firm AquaBounty, has been the center of considerable controversy as it represents the first GE animal approved for commercial sale and human consumption. While FDA has declared the fish safe to eat, and AquaBounty argues the fish will help feed the world, opponents stress that the potential adverse effects of the technology have not been properly vetted, and consumers will have no way to tell whether the salmon they purchase at the store is the engineered AquAdvantage product. Draft guidelines released by FDA when the salmon was approved do not require retailers to inform consumers that the fish is GE. Instead, the agency provided examples of voluntary statements, such as “genetically engineered,” or “This salmon patty was made from Atlantic salmon produced using modern biotechnology,” that producers  can consider using. The FDA policy makes it virtually impossible for shoppers wishing to avoid the GE fish to make an informed decision at the point of […]

(Beyond Pesticides, November 30, 2015) Last week, two studies were published that link neonicotinoid (neonic) insecticide exposure to detrimental effects in bees and butterflies. The first study, published in the international scientific journal Nature, found that bumblebees exposed to neonics suffered pollination services impairment that reduces their delivery to apple crops. The second study, published in the United Kingdom journal Peer J, used over 1,000 sites cataloged from 1984 to 2012 in the UK Butterfly Monitoring Scheme (UKBMS) database to point to the strong association between neonic use and butterfly population decline. These studies contribute to the mounting evidence that neonic insecticides are linked to pollinator decline. Neonics have increasingly been the subject of recent studies that highlight a causal relationship between neonic exposure  and harmful effects to pollinators, like foraging and reproductive complications. These effects are being identified by scientists all over the world, gradually negating industry criticism of study design. Andre Gilburn, PhD, and ecologist at the University of Stirling, led the butterfly study. He said, “Our study not only identifies a worrying link between the use of neonicotinoids and declines in butterflies, but also suggests that the strength of their impact on many species could be huge.” […]

(Beyond Pesticides, November 24, 2015) The Canadian province of Quebec has announced plans for a major overhaul of its pesticide laws in order to protect pollinators, public health and the wider environment. Canadian provinces, particularly Quebec and Ontario, have long led the way in crafting common sense pesticide legislation that responds to sound science on the dangers of these chemicals. The proposed reforms will focus on further restricting the most toxic pesticides allowed for use in both agriculture and residential pest control, including atrazine, chlorpyrifos, and the neonicotinoid class of insecticides, which are  widely implicated in pollinator declines. “Québec has made progress in recent years with respect to responsible pesticide management,” said the Quebec Minister of Sustainable Development, Environment and the Fight Against Climate Change. “However, the time is  right to intensify our efforts and become even more proficient at reducing the risks to health and the environment that are associated with pesticide use, particularly by supervising the use of highest-risk pesticides like neonicotinoids, which have a recognized major effect on bee mortality.” Quebec’s Pesticide Strategy 2015-2018  is structured  to incentivize farmers and home gardeners to choose lower risk pesticides through economic motivators such as levies, permits, and compensation fees. […]

(Beyond Pesticides, November 19, 2015) French scientists say that they have found the “missing link” between laboratory studies and field studies that assess the adverse effects of neonicotinoid (neonic) insecticides on bees. The study, published in Royal Society Journal Proceedings B, evaluates the effects of neonics on honey bees in field trials. After 15 years of research into the effects of neonicotinoids on bees, researchers had identified a gap between the results of toxicity assessments on individual bees in the laboratory and  impacts seen at the colony level in the field. The new two-year study made two discoveries: First, they found that field exposure to thiamethoxam combined with imidacloprid contamination is associated with a significant excess mortality in individual free-ranging bees.  Second, while colonies appeared to be able to compensate for the excess mortality and preserve population size and honey production, this was done at the expense of a change in brood laying patterns. Thus, this study provides an explanation for the “missing link” in the discrepancies between labs studies and field studies, where the former establishes harmful and fatal effects that had yet to be replicated in real-life conditions. Because the bees responded to the increased mortality with selective […]

(Beyond Pesticides, November 12, 2015) The U.S. Geological Survey (USGS) recently performed the first-ever study of pesticide residues on native bee populations and found that they are exposed to neonicotinoid insecticides, as well as other pesticides, at significant rates. This study digs deeper into a question  that was previously considered by a researcher who  studied chemical-intensive  apple orchards and linked a steep decline in wild or native bees to the application of pesticides. The USGS study  broadens understanding about the effects of toxic pesticides to native bee species, expanding field research that has principally focused on managed honey bee populations. The study tested for 122 different pesticides including bifenthrin, atrazine and chlorpyrifos, a chemical for which the U.S. Environmental Protection Agency (EPA) recently proposed to revoke all food tolerances in response to  a court-ordered deadline. According to study findings, 72% of bees tested positive for pesticide residues, raising concerns for the potential for unintended pesticides exposures where land uses overlap or are in proximity to one another.   Residues of pesticides found in bees in the study include  thiamethoxam, clothianidin, and imidacloprid, all of which are highly toxic neonicotinoids, a class of chemicals that have been linked to the global […]

(Beyond Pesticides, November 6, 2015) New York State Senator Tim Kennedy (D-NY) has called for a statewide ban on triclosan, one of the most prevalent antibacterial compounds found in common household products. Minnesota is the only state to have passed a triclosan  ban. If passed, the New York Bill (Bill S6070) would prohibit the sale of cleaning products containing triclosan, triclocarban, or derivatives of similar antibacterial compounds, and mark a clear victory for human health and safety interests within the state. Triclosan has been used for over 30 years in the U.S., mostly in a medical setting, but more recently in consumer products. Beyond Pesticides has generated extensive documentation  of the potential human and environmental health effects of triclosan and its cousin triclocarban, called on manufacturers to stop using triclosan in its products and retailers to stop carrying these products, and previously petitioned the Environmental Protection Agency (EPA) for the cancellation of registered products that contain the antibacterial pesticide. In May 2015, EPA issued its long-awaited response to the Citizen Petition filed by Beyond Pesticides and Food & Water Watch, denying the request. When introduced to the market in 1972, triclosan was confined to hospital and health care settings. Since […]

(Beyond Pesticides, November 3, 2015) The U.S. Environmental Protection Agency (EPA) is proposing to revoke all food tolerances for the organophosphate insecticide chlorpyrifos (also known as Dursban), a neurotoxic pesticide produced by Dow AgroSciences that poses particular risks to children and farmworkers. If EPA’s rule is finalized, chlorpyrifos would be effectively eliminated from use in agriculture 15 years after consumer uses were discontinued. However, other non-food uses, including golf courses, turf, green house and mosquito control are not affected by this decision and will remain. EPA’s proposed rule came on the day of a court-ordered deadline from the U.S. Court of Appeals Judge for the Ninth Circuit, M. Margaret McKeown. In August of this year, Judge McKeown ordered EPA to respond to a petition filed by Pesticide Action Network North America and the Natural Resources Defense Council nearly nine years ago. The lawsuit called on the agency to ban all uses of the insecticide in light of scientific evidence and public comments ignored by the agency after its cumulative risk assessment for organophosphate insecticides. In 2012, EPA imposed “no-spray” buffer zones around public spaces, including recreational areas, schools, and homes to reduce bystander exposure risks. Earlier this year, the agency […]

(Beyond Pesticides, October 30, 2015) The Environmental Protection Agency’s (EPA) Office of Pesticide Program (OPP) needs policies and procedures to manage pesticide petitions in a transparent and efficient manner, according to new report  that  highlights inadequacies in the way the agency responds to petitioners. The report, published by EPA’s Office of Inspector General, an independent office within EPA that investigates agency compliance with laws governing its programs, concludes that the lack of transparency and efficiency “leaves petitioners unaware of petition status, which can result in unreasonable delay lawsuits costing the agency time and resources.” While the public has the right to submit pesticide petitions to EPA and the agency is required to respond to these petitions “within a reasonable time,” there are no set requirements for what constitutes a specific time frame. However, petitioners can file a lawsuit claiming unreasonable delay if the petitioner finds that EPA has not responded within what the petitioner considers a reasonable amount of time. Of the 40 public petitions received by OPP from Fiscal Year 2005 through 2014, nearly a quarter of them are  associated with unreasonable delay lawsuits. The specific issues contributing to these delays involve: Petition documentation not being readily accessible; Some […]

(Beyond Pesticides, October 28, 2015) On the heels of a recent federal court decision that rejected the U.S. registration of sulfoxaflor, which cited inadequate and flawed review of the science on the chemical’s toxicity to bees, European beekeepers filed complaint that that asks the European Court of Justice to take the same action. The complaint  asks the court to cancel sulfoxaflor’s authorization. Sulfoxaflor is a neonicotinoid-like chemical that, like neonicotinoids, is highly toxic to bees. Three of the most widely used neonicotinoids are currently under a two-year European-wide moratorium which began December 2013, due to concerns about risks to bee populations. European beekeepers, Bee Life European Beekeeping Coordination, the Italian National Beekeeping Union (UNAAPI), and PAN Europe, filed the complaint which cites a published  negative opinion on Dow AgroScience’s sulfoxaflor by the European Food Safety Authority (EFSA). According to EFSA, the pesticide is categorized as ”˜highly toxic to bees’ and it identified crucial toxicity data gaps, which according to the beekeepers, makes a proper risk assessment for bees impossible. Despite these facts, the European Commission’s Directorate-General for Health and Food Safety (DG Sante) and the EU member states authorized sulfoxaflor in July 2015, completely bypassing the pesticide regulation, the complaint […]

(Beyond Pesticides, October 26, 2015) Last week, Pop Weaver, the second largest popcorn supplier in the country, released an official statement on its commitment to “removing 50 percent of its neonicotinoid usage in 2016, 75 percent in 2017, with a long-term commitment of further reducing usage by working with agricultural universities and those companies supplying neonicotinoids to the seed industry.” Widely-used neonicotinoids (neonics), which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies  and by beekeepers  as the major contributing factor in bee decline. This commitment is a response to a campaign led by Center for Food Safety (CFS), which asked citizens to sign a petition asking Pop Weaver, and other large popcorn suppliers, to protect bees and other pollinators by phasing out the use of neonicotinoid-coated corn seed. Over 37,000 people have signed their petition. Americans eat, on average, 17.3 billion quarts of popcorn each year; each American eats about 68 quarts. According to CFS, there are roughly 40 insecticides currently registered for use as an active chemical on popcorn, including 3 bee-toxic neonicotinoid chemicals: clothianidin, thiamethoxam, and imidacloprid. Between  79 and 100 […]

(Beyond Pesticides, October 23, 2015) Tests on produce collected by California’s Department of Pesticide Regulation (CDPR) for 2014 show high levels of  illegal toxic pesticide residues. The CDPR report found 1 percent of produce containing an excess amount of pesticide residues, and an additional 5.5 percent of produce tested contained illegal residues of pesticides that are not allowed for use on that product. Additionally, the data shows residues of a banned  chemical, which was taken off the market  over 20 years in the U.S. due to health concerns related to farmworker exposure. These findings showcase issues related to  system-wide failure in  enforcement. Advocates stress that violations may continue to occur due to inadequacies in regulations governing enforcement authorities, which include warnings or low fines for violators. In raising concerns about the safety of food grown with chemical-intensive methods, advocates point to the need to expand the transition to organic agriculture for better protection of public health and safety. The highest percentage of illegal pesticides was found on cactus pads and cactus fruit imported from Mexico. Some of the other tainted fruit and vegetables include limes, papaya, summer squash, tomatillos, chili peppers, and tomatoes, also from Mexico, ginger imported from China, […]

(Beyond Pesticides, October 22, 2015) With increasing consumer concern about genetically engineered (GE) food, yesterday  the U.S. Senate Committee on Agriculture, Nutrition, and Forestry held a hearing,  entitled Agriculture Biotechnology: a Look at Federal Regulation and Stakeholder Perspectives, that critics called lopsided. Most witnesses characterized GE food as safe or side-stepped the issue of safety, as government witnesses refused to distinguish GE from conventional food and opposed food labeling. “This is the first time in 10 years we’ve had a hearing on biotech. I guess we’re a little late, but we’re here,” said chair of the committee, Senator Pat Roberts (R-KS). The ranking  minority member of the committee, Senator  Debbie Stabenow (D-MI)  said,  “Biotechnology is proven to be safe, beneficial, and I believe will play a major role in helping to solve these dual global challenges of climate change and global food security,” Central to the hearing is the the issue of labeling food products containing GE crops. Senator Stabenow called for the adoption of legislation on GE food labeling, presumably with language that will preempt the authority of states to adopt more stringent labeling standards. Senator Stabenow said that she wants labeling that “doesn’t stigmatize biotechnology.” The GE food […]

(Beyond Pesticides, October 21, 2015) Last week, Responsible Industry for a Sound Environment (RISE), an umbrella group representing pesticide manufacturers, celebrated its 25th year anniversary, touting its efforts to roll back critical protections from pesticide use in the U.S. The group emphasizes its role in quashing local government’s right to restrict pesticide use within its jurisdiction  after the Supreme Court, in Wisconsin Public Intervenor v. Ralph Mortier (1991), upheld local  authority under federal pesticide law. RISE, formed out of the National Agricultural Chemicals Association to fight government regulation at the federal, state, and local level, launched with a  plan to defeat those opposing pesticide use in favor of sustainable practices, including concerned mothers, progressive businesses, and local and national health and environmental advocates. The platform  RISE articulates  showcases its plans to influence regulators and consumers to allow the widespread and less restricted use of pesticides. In the 1990’s, RISE joined with another industry group, the American Legislative Exchange Council (ALEC), to seek the adoption in state legislatures across the country pesticide preemption laws, which were adopted in over 40  states. These laws prevent local governments from adopting  their own restrictions governing pesticide use  on private property. At one point, the […]

(Beyond Pesticides, October 20, 2015) Exposure to neonicotinoid (neonic) pesticides results in profound negative impacts to the health of honey bee queens, according to an international team of researchers led by Geoff Williams, MD, PhD, at the University of Bern in Switzerland. While most studies to date have investigated how neonics effect the health of individual workers or overall colony fitness, Dr. William’s study, Neonicotinoid pesticides severely affect honey bee queens, is one of the first to focus on the health of honey bee queens. Neither the European Union nor U.S. Environmental Protection Agency (EPA) study the impacts of pesticides on queen health before allowing a pesticide to market. The results of this research are particularly concerning, given widespread anecdotal evidence from beekeepers across the globe that ”˜poor quality queens’ are playing a role in bee declines. To test the impacts of these chemicals on queen honey bees, scientists exposed a sample of 29 queens to field-realistic levels of the neonics  clothianidian and thiamethoxam (1 parts per billion and 4 ppb respectively), and compared them to a population of 28 control queens, which were not treated with neonics. Both groups experienced similar environmental circumstances in terms of food availability, rearing […]

(Beyond Pesticides, October 19, 2015) Monsanto, the major producer of Roundup (glyphosate), has found itself in hot water recently, as personal injury lawsuits pile up over the link between glyphosate exposure and non-Hodgkin’s Lymphoma (NHL). Personal injury law firms around the U.S. have found a multitude of plaintiffs and are preparing for what could be a “mass tort” action against Monsanto for knowingly misinforming the public and farmworkers about the dangers of the chemical. The latest lawsuit was filed October 14 in Delaware Superior Court by three law firms representing three plaintiffs. One plaintiff in the Delaware lawsuit, Joselin Barrera, 24, a child of migrant farmworkers, relates  her non-Hodgkin lymphoma (NHL) to glyphosate exposure. Elias de la Garza, a former migrant farm worker and landscaper diagnosed with NHL, has a similar claim. These follow other lawsuits filed last month in New York and California that  accuse Monsanto of knowing that glyphosate was hazardous to human health. Monsanto “led a prolonged campaign of misinformation to convince government agencies, farmers and the general population that Roundup was safe,” the lawsuit states. Glyphosate is touted as a “low toxicity” chemical and “safer” than other chemicals by the Environmental Protection Agency (EPA) and industry […]

(Beyond Pesticides, October 15, 2015) A new study, published in Environmental Science & Technology, has found that wildflowers bordering fields that are treated with neonicotinoids contain a higher concentration of the bee-toxic pesticides than the actual treated fields, pointing out an often overlooked avenue of exposure for bees. Widely-used neonicotinoids, which as systemic chemicals move through a plant’s vascular system and express poison through pollen, nectar, and guttation droplets, have been identified in multiple  peer-reviewed studies  and by beekeepers  as the major contributing factor in bee decline. The study, titled Neonicotinoid Residues in Wildflowers, A Potential Route of Chronic Exposure for Bees, discovered neonicotinoid insecticides in wildflowers, including Hogweed and Poppy pollen (up to 86ppb and 64ppb, respectively). The study’s authors  found higher concentrations of neonicotinoids in wild flowers in field margins than in Oilseed rape flowers in the adjacent neonicotinoid treated crop — on average 15ppb vs. 3ppb.   They also found that more than 97% of the neonicotinoids being brought into the hive by honey bees are from wildflowers, while only 3% are  from the crop. Researchers have found  that chronic exposure to neonicotinoids increases neuronal vulnerability to mitochondrial dysfunction in the bumblebee. In other words, these pesticides […]

(Beyond Pesticides, October 9, 2015) Last week, the Environmental Protection Agency (EPA) released preliminary human health and ecological risk assessments for seven organophosphate pesticides (OPs) and announced the public open comment period for those chemicals. These risk assessments come as a result of the required periodic registration review, as required by  the Federal Insecticide, Fungicides, and Rodenticide Act. In general, OPs are highly toxic and many have been voluntarily removed from the market, considerably restricted, or denied reregistration. Unfortunately, EPA continues to rely on risk mitigation for individual OPs instead of phasing them out altogether. Seven OPs ­ ­—dimethoate, dictrotophos, chloyrophos-methyl, tribufos, terbufos, profenofors, and ethoprop—are among the first wave of chemicals whose preliminary risk assessments have been completed under the registration review program. Each of these was found by EPA to inhibit the enzyme acetylcholine esterase (AchE), which ultimately leads to neurotoxic  central nervous system effects. This information is not new, however. In 2012, University College London found long-term low-level exposure to OPs produces lasting damage to neurological and cognitive functions. In 2013, at least 25 children died after eating school lunches contaminated by OPs. One OP in particular, chlorpyrifos, chlorpyrifos (Dursban), is currently under petition for the same […]

(Beyond Pesticides, September 29, 2015) Last week, the City of Reno, Nevada officially approved a Pesticide-Free Parks program aimed at improving the health of its residents and the local environment. In addition to two downtown parks, Neighborhood Advisory Boards within each of City’s five wards chose two parks to join the program, bringing the total to 12 pesticide-free parks. The program is an outgrowth of resident concern over the use of pesticides linked to cancer, asthma, and learning disorders, as well as impacts to local water quality. Beyond Pesticides worked to support the pesticide-free parks movement by sponsoring a training session taught by nationally renowned turfgrass expert Chip Osborne on how to transition to organic practices. “This is a major win for the city in regards to our priority of providing and maintaining safe and healthy neighborhoods,” Ward 2 Reno City Councilmember Naomi Duerr told ABC8. “Community input will continue to drive the important decisions we make.” According to a staff report released by the Reno Department of Parks, Recreation and Community Services, there is not expected to be any burdensome financial implications put upon the City as a result of the program. “There will be no cost implications as […]

(Beyond Pesticides September 21, 2015) Last Thursday, the  Transportation and Environment (T&E) Committee in Montgomery County, Maryland voted 2-1 to strip major provisions of the Healthy Lawn Bill 52-14, including a  ban of (i) cosmetic use of lawn pesticides throughout the county on private and public property and (ii) the treatment of playing fields with hazardous pesticides. The amended bill retains a pesticide ban on all playgrounds and sets up an organic pilot program on some  playing fields and parks. The bill’s prime sponsor and two of its cosponsors said they will work to gather the five votes necessary to restore critical protections for human health and the environment. The T&E Committee voted 2-1 on substitute legislation, proposed by Committee Chair Roger Berliner, to remove the central portions of the bill intended to transition Montgomery County land, including public and private property, to non-toxic sustainable management practices. While Committee members Nancy Floreen, an original co-sponsor of the bill and Mr. Berliner both voted for the substitute legislation, Council member Tom Hucker, a lead co-sponsor of the bill rejected the changes, stating that the county had a “very clear responsibility to protect public health.” Joining the committee discussion were Montgomery County […]

(Beyond Pesticides, September 17, 2015) On Tuesday, the City Council of Lafayette, Colorado unanimously approved a resolution to prohibit bee-toxic neonicotinoid insecticides on city property. The resolution restricts the use of neonicotinoids on any land owned or operated by the city, including public rights-of-way, parks, playing fields, watersheds and ditches, open space lands, and public landscapes. Modeled on  a resolution passed in May by neighboring Boulder city, the new resolution has been propelled through the City Commission with  support from grassroots organizations, including Bee Safe Boulder and Pesticide Free Boulder County Coalition. The resolution affirms that the City of Lafayette: Not purchase or use any neonicotinoid pesticides on city owned or operated land; Restrict city and agricultural contractors from using neonicotinoids like imidacloprid, clothianidin, thiamethoxam, dinotefuran, etc.; Provide exceptions only when emergency situations where the life or health of a valuable, important land asset is at risk, such as a valuable tree or golf course, and when the neonicotinoid application is the most effective option; Urge all residents and business in Lafayette to suspend neonicotinoids for use in seed treatment, soil application, foliar treatment, and other bee-attractive settings; Purchase landscape materials that have not been treated with neonicotinoids and urge […]

(Beyond Pesticides, September 16, 2015) In a letter posted to the federal docket, the U.S. Department of Agriculture (USDA) states that it is opposed to U.S. Environmental Protection Agency’s (EPA) recent proposal to restrict pesticides highly toxic to bees on sites where managed bees are present, saying the measure “has not established the need for such a prohibition.” In its position, USDA  cites economic impacts to farmers and lack of a cost/benefit analysis. USDA’s critique of EPA’s proposal contrasts with a decision handed down last week by a federal court that ruled EPA should not ignore risk concerns for bees and rejected the registration of a pesticide known to be highly toxic to bees, highlighting a lack of collaboration and understanding between federal agencies in advancing  pollinator protection. USDA communicated its challenge to EPA despite the growing body of science on the hazards of neonicotinoid insecticides and findings in Europe that their restriction does not undermine crop productivity. Last May,  EPA announced a new proposal  to temporarily prohibit foliar applications of pesticides that are acutely toxic to bees during plant bloom and when managed bees are on site and under contract. The proposal received a mixed response, with many from […]

(Beyond Pesticides, September 15, 2015) A study released this week in the journal Pediatrics finds that children’s exposure to pesticides in and around the home results in an increased risk of developing certain childhood cancers. Researchers made their findings through a meta-analysis, reviewing 16 epidemiological studies published since 1993 on the link between childhood cancer and pesticide exposure. Based on their findings, the authors of the study suggest “”¦public health policies should be developed to minimize childhood exposure to pesticides in the home,” and that “[e]very effort should be made to limit children’s exposure to pesticides.” While most meta-analytical reviews previously conducted on the link between pesticides and childhood cancer looked at parental exposure or agricultural exposure, the current study from scientists at the Harvard T.H Chan School of Public Health focuses in on residential exposure in and around a child’s home. Authors found that cancer risks were connected most closely to the type of pesticide used and the location where it was applied. For example, while residential herbicide use was associated with an increased risk of leukemia, the link between outdoor insecticide use and childhood cancers was not found to be statistically significant. However, exposure to insecticides inside the […]
