(Beyond Pesticides, February 20, 2015) A broad-based coalition is urging Canada’s Prime Minister Stephen Harper to put a stop to proposed changes to federal aquaculture regulations, citing damage to the environment and existing businesses. The proposed amendments to the federal Fisheries Act would exempt the aquaculture industry from provisions that “prohibit the release of deleterious substances into water frequented by fish.” Coalition members are worried that the changes will result in pesticides routinely being dumped into the Bay of Fundy,  located between the Canadian provinces of Nova Scotia and New Brunswick, and remove Environment Canada’s role in aquaculture activities, said spokeswoman Maria Recchia, the executive director of the Fundy North Fishermen’s Association. Aquaculture, which refers to the breeding, rearing, and harvesting of aquatic organisms such as fish, shellfish, and plants, provides half of the world’s seafood. According to  Food and Water Watch, offshore aquaculture follows an industrial agriculture model which grows thousands of animals in a confined environment. For fish, however, this confined space is in the ocean, meaning all of the waste products from the operation flow directly into the ocean. This includes excess feed and chemicals that are used, such as antibiotics and pesticides, to treat or prevent […]

(Beyond Pesticides, January 30, 2015) Extensive exposure to common chemicals may be linked to an earlier start of menopause, according to a new study out of Washington University School of Medicine in St. Louis. Researchers of the study found that women whose bodies have high levels of these chemicals, including three pesticides, experience menopause two to four years earlier than women with lower levels of the chemicals. The pesticides found to have a significant correlation with an early start in menopause were p,p’-DDE (a metabolite of DDT), β-hexachlorocyclohexane (a byproduct of the production of lindane), and mirex. All three pesticides are organochlorine insecticides or their breakdown products that have been banned for use  in the U.S., but continue to persist in the environment and in the food chain. The study, Persistent Organic Pollutants and Early Menopause in U.S. Women, published this week in the journal PLoS ONE, investigates the link between levels in blood and urine of 111 endocrine-disrupting chemicals (EDCs), or chemicals that interfere with the body’s hormonal activity, and focused on known reproductive toxicants or persistent environmental contaminants. The findings suggest a significant association between 15 chemicals —nine polychlorinated biphenyls (PCBs, which are industrial products), three pesticides, two […]

(Beyond Pesticides, January 13, 2015) Over a decade after consumer opposition halted multinational agrichemical business Monsanto’s plans to develop genetically engineered (GE) herbicide-resistant wheat, the company is trying again. This time, Monsanto’s goal is to create wheat that is resistant to three different herbicides; glyphosate, glufosinate, and dicamba. Although over 90% of corn, soybean, and cotton grown in the United States are GE, no GE wheat is currently allowed to be planted. In 2013, a farmer in Oregon discovered the presence of Monsanto’s original Roundup-Ready wheat, developed to be resistant to glyphosate, in his field despite the company’s plans to abandon the strain and claims to have destroyed the crop  a decade earlier. The company had restarted extensive field trials back in 2011. An investigation by the U.S. Department of Agriculture (USDA) determined that the contamination was an “isolated incident.” It was unable to determine exactly how the wheat came to grow in the Oregon farmer’s field. However, shortly after the agency closed its investigation, another farmer in Montana detected the GE strain in his wheat fields. The recurrence of this incident reveals the contamination event not to be an isolated incident. It instead demonstrates the threat that these crops […]

(Beyond Pesticides, January 7, 2015) On Monday, the U.S. Environmental Protection Agency (EPA) released a revised human health assessment for the insecticide, chlorpyrifos, which finds risks to workers who mix, load and apply chlorpyrifos, and that the chemical has the potential to pose risks to drinking water in small watersheds. The assessment also notes that EPA will retain the 10X (10-fold) safety factor to protect children from all routes of exposures. EPA’s latest finding confirms long-standing scientific data that  has documented chlorpyrifos’ toxicity to humans and environmental contamination. However, despite these findings, EPA proposes to place additional restrictions on chlorpyrifos’ use, instead of a widespread ban. This latest assessment updates the June 2011 preliminary human health risk assessment, which was widely criticized by environmental and farmworker groups. EPA is releasing this assessment based on new information received since 2011, including public comments. The assessment is, in part, in response to a petition submitted by Natural Resources Defense Council (NRDC) and Pesticide Action Network (PAN) in 2007, which called on the agency to ban all uses of the insecticide. In 2000, EPA orchestrated a voluntary cancellation with the manufacturer Dow AgroSciences of  most residential uses of chlorpyrifos to limit children’s exposure, […]

(Beyond Pesticides, January 6, 2015) At the close of 2014, the U.S. Fish and Wildlife Service (FWS) announced plans to conduct a year-long status review of the monarch butterfly to determine whether the species is eligible for protection under the Endangered Species Act (ESA). FWS is taking this action as result of an August 2014 legal petition filed by health and environmental groups that presented substantial information indicating that listing under the ESA may be warranted. In November 2014, Beyond Pesticides joined over 200 environmental groups and businesses in a letter asking for federal protection for monarch butterflies in the wake of shocking declines. The North American monarch butterfly population fell by 90 percent in the past 20 years, dropping from a high of approximately  one billion in the mid-1990s to fewer than 35 million butterflies in the winter of 2013-2014— the lowest number ever recorded. Each year monarch butterflies travel over 2,000 miles between Canada, the U.S., and Mexico, across multiple generations, to reach their winter hibernation grounds in late October. As FWS indicates, this journey has become “more perilous for many monarchs” due to threats along their migratory paths. Scientists believe the butterfly’s decline is being driven in […]

(Beyond Pesticides, December 3, 2014) The U.S. Department of Agriculture (USDA) announced last week that nearly 2,500 applicants will receive disaster assistance through the Emergency Assistance for Livestock, Honey Bees, and Farm-Raised Fish Program (ELAP) for losses suffered from Oct. 1, 2011, through Sept. 30, 2013. The program, re-authorized by the 2014 Farm Bill, provides disaster relief for farmers and producers not covered by other agricultural disaster assistance programs. Beekeepers who reported losses due to colony collapse disorder will be eligible, a move that many in the beekeeping industry welcome. ELAP provides disaster relief to livestock, honey bee, and farm-raised fish producers not covered by other agricultural disaster assistance programs. Eligible losses may include excessive heat or winds, flooding, blizzards, hail, wildfires, lightning strikes, volcanic eruptions, and diseases, or in the case of honey bees, losses due to colony collapse disorder. According to USDA, beekeepers, most of whom suffered honey bee colony losses, represent more than half of ELAP recipients. Enrollment for the program began last spring and ended in August 2014, and eligible farmers, beekeepers and producers must have submitted documentation of losses for enrollment in the program. Beekeepers have been experiencing historical losses in their bee hives and […]

(Beyond Pesticides, December 2, 2014) Last week, the government of Ontario, Canada proposed a plan to reduce the use of neonicotinoid (neonic)-treated corn and soybean seeds by 80% as part of a broad initiative to improve pollinator health. It sets a goal of reducing over-winter honey bee deaths to 15% by 2020, and calls for the development of a comprehensive Pollinator Health Action Plan. To address the regulation of treated seeds, Ontario’s pollinator health proposal recommends the creation a new class of pesticides to include seeds treated with pesticides. The government would then restrict the sale and use of neonic-treated corn and soybean seed. In the U.S., EPA establishes the “treated article exemption” (40 CFR 152.25(a))  as  limiting its ability to regulate  seeds, under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA),  that act  as  toxic pesticides when applied to agricultural fields and landscapes. According to  EPA, the treated article exemption,  “allows an exemption for: An article or a substance treated with or containing a pesticide to protect the article or substance itself (for example, paint treated with a pesticide to protect the paint coating, or wood products treated to protect the wood against insects or fungus infestation), if the […]

(Beyond Pesticides, November 24, 2014) Last Wednesday, a special Task Force on Pollinator Health in Oregon delivered a series of recommendations to the Oregon legislature on how to help the state’s honey bees, native bees, and other pollinators,but failed to address the clear threat that neonicotinoid insecticides pose to pollinators. Because the task force only prioritized consensus recommendations, groups representing pesticide manufacturers, retailers, and the nursery industry were able to stifle advice on protecting pollinators from highly toxic, long-lived systemic neonicotinoids and other potential pesticide threats. Instead, the consensus decisions include: expansion of outreach and education, supporting new research, and increasing pollinator habitat. Five of the eight voting members also supported targeted oversight of pesticide use. According to Xerces Society, one of the conservationist members of the task force, industry’s opposition to targeted oversight of pesticide use stood  in stark contrast with the scientist, master gardener, beekeeper and conservationists on the task force. Actions opposed only by industry representatives include requiring a pesticide applicator’s license for anyone who regularly uses pesticides as part of his or her job, halting the use of two highly toxic, long-lived neonicotinoid insecticides (clothianidin and thiamethoxam) on linden trees, and increasing consumer awareness about whether […]

(Beyond Pesticides, November 19, 2014) A group of doctors and nurses is urging the Ontario government to ban neonicotinoid pesticides, blamed for the decline of bees and other insect pollinators. As Canada’s first neonicotinoid campaign organized by doctors and nurses, the Canadian Association of Physicians for the Environment and the Registered Nurses’ Association of Ontario say that these pesticides are a “major threat to both nature and people.” The doctors and nurses in Ontario, Canada, now urging the province to ban the pesticides adds to growing pressure on the Ontario government to take action on neonicotinoids (neonics), the insecticide class of chemicals linked to the deaths of bees across Canada and the U.S. Central to the initiative is an advertising buy which starts this week on the Toronto subway system. The ads show an anxious child beneath the caption, ”˜Doctors and Nurses say neonic pesticides hurt our bees and us.’ The Canadian Association of Physicians for the Environment (CAPE) and the Registered Nurses Association of Ontario (RNAO) also plan to meet with the Ontario Environment Minister, Glen Murray, later this year  to urge the government to ban the chemicals. CAPE is the campaign’s main funder, with contributions from David Suzuki […]

(Beyond Pesticides, October 31, 2014) Without any mention of the role of pesticides in bee decline, or emphasis on organic practices to help pollinators, Agriculture Secretary Tom Vilsack announced Wednesday that more than $4 million in technical and financial assistance will be provided to help farmers and ranchers in the Midwest improve the health of honey bees. The announcement renews and expands on a $3 million pilot investment last spring to create pollinator-friendly habitat in five Midwestern states. The effort responds to the Presidential Memorandum, which directs USDA to expand the acreage and forage value in its conservation programs. The Memorandum, issued at the close of National Pollinator Week 2014, directed federal agencies to establish a Pollinator Health Task Force, and tasked agency leads at the U.S. Department of Agriculture (USDA) and U.S. Environmental Protection Agency (EPA) to develop a pollinator health strategy within 180 days that supports and fosters pollinator habitat. “The future of America’s food supply depends on honey bees, and this effort is one way USDA is helping improve the health of honey bee populations,” Vilsack said. “Significant progress has been made in understanding the factors that are associated with Colony Collapse Disorder and the overall health […]

(Beyond Pesticides, October 28, 2014) Last week the White House Council on Environmental Quality (CEQ) announced new guidelines for federal agencies to incorporate pollinator friendly practices at federal facilities and on federal lands. Critical to pollinator health within these guidelines is a requirement that agencies should “[a]cquire seeds and plants from nurseries that do not treat their plants with systemic insecticides.” Further, the document states that, “Chemical controls that can adversely affect pollinator populations should not be applied in pollinator habitats. This includes herbicides, broad spectrum contact and systemic insecticides, and some fungicides.” Following the U.S. Fish and Wildlife Service’s announcement this summer eliminating neonicotinoid use on National Wildlife Refuges, this represents the latest instance of a federal entity recognizing the danger caused by systemic pesticides, and recommending against their introduction in pollinator habitat. However, while the CEQ’s new pollinator friendly practices for federal facilities provide great information on appropriate plants by region, encourage education and outreach to citizens, and prescribe neonicotinoid-free plant selection, the guidelines fall just short of establishing or encouraging an organic management system for federal facilities. Although the report recommends against using chemical controls in established pollinator habitats, and indicates that “[I]n general, the use of […]

(Beyond Pesticides, October 20, 2014) The U.S. Environmental Protection Agency released a report Thursday that soybean  seed treatments with neonicotinoid insecticides provide little or no overall benefits in controlling insects or improving yield or quality in soybean production. While pesticide manufacturer Syngenta has petitioned EPA to raise the allowable levels of another systemic pesticide thiamethoxam on a number of crops, EPA’s report confirms  scientific findings  that these chemical treatments are unnecessary and inefficacious. 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 report concludes that not only is there no increase in soybean yield when compared to using no pest control at all, but also the potential benefit of neonicotinoid seed treatment is not likely to be large or widespread throughout the U. S. EPA also found that seed treatments fail to provide protection from target pests during critical times of plant activity, ultimately leading to the assessment that “much of the existing usage on soybeans is prophylactic in nature.” “This report demonstrates, yet again, the need for […]

(Beyond Pesticides, October, 16, 2014) Despite a massive outpouring of public opposition, the U.S. Environmental Protection Agency (EPA) announced yesterday that it has registered Enlist Duo ®, officially putting the rubber stamp of approval on the sale and use of a new wave of genetically-engineered (GE) 2,4-D tolerant crops. Developed by Dow AgroSciences, Enlist Duo ® is an herbicide that incorporates a mix of glyphosate and a new formulation of 2,4-D, intended for use on GE Enlist-Duo ®-tolerant corn and soybean crops. While registration of the herbicide was anticipated by most of the public since the U.S. Department of Agriculture (USDA)’s approval of the Enlist Duo ®-tolerant crops in mid-September, the announcement still comes as a disappointing shock, demonstrating the failings of the U.S. pesticide and agricultural regulatory system to put people and the environment before economic incentives and industry bottom lines. “EPA approval of this herbicide sets a dangerous precedent,” says Jay Feldman, executive director of Beyond Pesticides. “Instead of looking to alternatives, regulators are signaling that the answer to widespread weed resistance is more toxic products that endanger farmworkers and farming communities.” As Beyond Pesticides noted in its comments submitted to EPA in June of this year, the […]

(Beyond Pesticides, September 2, 2014) U.S. Representative Henry Waxman (D-Calif.) sent a letter to the U.S. Environmental Protection Agency (EPA) last week asking them a poignant question: Why didn’t the human health risk assessment of Dow’s newest 2,4-D-based herbicide apply the ten-fold safety factor required by national law to protect children and infants? The question is a good one and events leading up to it began back in April 2014, when EPA opened up a public comment period for Dow AgroSciences’s application to expand the use of its 2,4-D choline salt herbicide, known as Enlist Duo ®, on 2,4-D-tolerant corn and soybeans. This application was the next step in ushering in a new wave of genetically-engineered (GE) crops sought to replace the quickly waning glyphosate-resistant or Roundup Ready ® varieties. As EPA described on its Enlist-Duo ® webpage, “Weeds are becoming increasingly resistant to glyphosate-based herbicides and are posing a problem for farmers. If [the Enlist Duo ® application is] finalized, this action would provide an additional tool to reduce the spread of glyphosate resistant weeds.” In other words, because of the overuse of glyphosate on GE glyphosate-resistant crops and the resulting development of weeds across the U.S. showing resistance […]

(Beyond Pesticides, August 18, 2014) In a victory for environmental groups, conservationists, and fishing groups, the U.S. Environmental Protection Agency (EPA) finalized a settlement last Wednesday to restore no-spray buffer zones around waterways to protect imperiled salmon and steelhead from five toxic pesticides.   An initial agreement was reached in June, when it underwent public comment, and was ultimately filed August 13 without any substantive changes. The settlement follows litigation filed by Earthjustice, representing the Pacific Coast Federation of Fishermen’s Associations, the Northwest Coalition for Alternatives to Pesticides, and Defenders of Wildlife, back in 2010 that called for EPA adoption of reasonable fish protections from the insecticides. The buffers apply to salmon habitat throughout California, Oregon, and Washington to prohibit aerial spraying of broad-spectrum pesticides diazinon, chlorpyrifos, malathion, carbaryl, and methomyl within 300 feet of salmon habitat and prohibit ground-based applications within 60 feet. “Poisoning salmon rivers puts our people out of work while creating an unnecessary and expensive public health hazard,” said Glen Spain of the Pacific Coast Federation of Fishermen’s Associations, a West Coast commercial fishing industry trade association and co-plaintiff. “This agreement helps the coastal and inland communities that depend on salmon for their livelihoods and provides […]

(Beyond Pesticides, August 14, 2014) Pesticides are not the first thing to pop into mind when peering into a hot mug of steaming, pale green or murky black tea first thing in the morning. A recent report published by Greenpeace India announced the results of an investigation that tested for pesticide residues in branded tea. The verdict? Nearly 94% of the tea samples tested contained at least one of 34 different pesticides, while over half contained a toxic cocktail of more than 10 different pesticides. The residues found include DDT, which was banned for use in agriculture in India since 1989, and endosulfan, which was banned in 2011 by the Indian Supreme Court. Over half of the 49 samples contained illegal pesticides — either those that are not approved for use in tea cultivation or exceeded recommended limits. These pesticides include ones that have been long banned from agriculture and use in tea cultivation (DDT and triazophos), suspected mutagens and neurotoxicants (monocrotophos), and insecticides associated with the global decline in bee populations (neonicotinoids like thiacloprid and thiamethoxam). The most frequently detected pesticides include thiamethoxam (78%), cypermethrin (73%), acetamiprid (67%), thiacloprid (67%), DDT (67%), deltamethrin (67%), dicofol (61%), imidacloprid (61%), and […]

(Beyond Pesticides, July 24, 2014) Last week, the U.S. Environmental Protection Agency (EPA) denied an emergency application to use a hazardous pesticide, propazine, on 3 million acres of Texas cotton fields, after groups representing environmental, public health, and organic farm interests urged the agency to reject the request based on environmental effects and the predictable nature of the weed resistance to currently used chemicals. Despite determining “that an urgent and non-routine condition exists for Texas growers” when certain weed-densities are reached, EPA’s primary reasons for denying the application focused on health and environmental concerns of the pesticide. As EPA explained, “When conducting human health risk assessment for new use the Agency must first consider the risk profile for currently registered uses and determine if an additional use can be added to the cup.” This aggregate risk assessment is required under the Food Quality Protection Actand in the case of propazine, EPA found that “drinking water estimates suggest that risks from drinking water alone may lead to unacceptable risks . . . .” “While we disagree with the EPA that this meets any of the criteria for emergency exemption, we applaud the EPA for putting the health of people and the […]

(Beyond Pesticides, July 9, 2014) Beyond Pesticides is pleased to announce the winners of our first National Pollinator Photo Contest! The much anticipated three grand prize winners to be featured in the Fall issue of Pesticides and You are (pictured left to right below): Delbert Contival, in Kauai HI, with his photo “Bee loves Lotus Flower;” Darla Young, in Sheridan, AR with her photo: “Sitting pretty on a cone flower;” and Pierre Mineau, in Spring Island Canada, with his photo, “Bumble bees at St. John’s wort flowers in my backyard.” Winners were chosen by guest judge Deborah Jones, art director for National Geographic Society. Because there were so many excellent shots, Ms. Jones remarked that it took much longer than she anticipated to judge the contest. “During my career at National Geographic as an art director, I have been privileged to work with the best photographs in the world. I am a lifetime gardener and photographer, and I am happy to be a judge for such an important organization, and to help promote the beauty and importance of pollinators,” said Ms. Jones, “This was quite a challenge, because there were so many outstanding photographs. I thought in terms of choosing […]

(Beyond Pesticides, June 6, 2014) On June 4,  after a two year dispute between the Environmental Protection Agency (EPA) and a coalition of conservation organizations and fishing groups, an agreement  was finally reached to set reasonable no-spray buffer zones to protect salmon from five harmful insecticides: diazinon, chlorpyrifos, malathion, carbaryl, and methomyl. These buffer zones protect salmon habitat by stopping aerial spraying of pesticides within 300 feet, and ground based spraying within 60 feet of salmon supporting waters. According to the agreement, it also provides detailed notifications to state regulators, pesticide applicators, farmers and the public about the mandatory no-spray buffer zones. These stipulations will remain in place until the National Marine Fisheries Service has completed their analysis of the impacts of those five pesticides.  Then, once the analysis is completed, EPA will execute permanent protections based on their findings. EPA is required by law under the Endangered Species Act to protect what little salmon are left on the Pacific Coast. Salmon are a  critical indicator of how well we are maintaining both marine and terrestrial ecosystems, because their habitats are in streams, lakes, rivers, estuaries and the ocean. The fish  are extremely sensitive to changes in water quality, and […]

(Beyond Pesticides, June 5, 2014) Environmental advocacy groups filed an Administration Objection and a court appeal last week in order to challenge the Environmental Protection Agency’s (EPA) refusal to quickly correct errors in pesticide registrations and immediately implement measures to protect children from exposure to dangerous pesticides that drift from fields during and after application. EPA’s continued refusal to protect children’s health from pesticide drift is being criticized by numerous environmental, health, and farmworker advocacy groups. The groups, which include  United Farmworkers, Pineros y Campesinos Unidos del Noroeste, Pesticide Action Network of North America, Sea Mar Community Health Centers, California Rural Legal Assistance Foundation, Physicians for Social Responsibility, and Farm Labor Organizing Committee, originally filed a petition back in 2009 titled “Pesticides in the Air””Kids at Risk: Petition to EPA to Protect Children from Pesticide Drift (2009).” The petition asked that the agency properly comply with an existing law that requires EPA to protect children’s health from exposure to pesticides that drift from fields and orchards. After a more than four-year wait and a court appeal, EPA finally provided a response last March. These groups object to EPA’s recent response to their 2009 petition on the basis of two issues, […]

(Beyond Pesticides, March 13, 2014) Part deux of a 2012 study finding that sperm counts in French men had decreased 30% over the past 16 years came to a second startling conclusion in a 2014 analysis: the cause for those dramatic decreases may be pesticides. 2012 Sperm-Count Study Published in the scientific journal Human Reproduction, the landmark 2012 study showed an alarming 30 percent decrease in sperm counts across France between 1989 and 2005. Because the data for the 2012 study were drawn from Fivnat ””a French assisted reproduction technology database”” researches made sure to limit analysis to 26,600 sperm samples from otherwise virile 35-year-old men whose partners’ fallopian tubes were either blocked or missing. This control was added to ensure that the each couple’s infertility was due to these latter problems and not a problem with the man’s sperm. Broken down, the 2012 studies identified a 1.9 percent continued annual dip in sperm concentration and also found that there was a significant 33.4% decrease in the percentage of normally formed sperm over the entire 16-year period. At the time of release, the 2012 study’s authors wrote: “To our knowledge, it is the first study concluding a severe and general […]

(Beyond Pesticides, February 19, 2014) Over 30 environmental and consumer groups in New York are protesting new language in the state’s proposed budget that strips away the requirement that commercial pesticide applicators report where pesticides are used, what kind of pesticides they use and how much. The new reporting regulation will require that sales are recorded at the register, instead of where they are applied, eroding the public’s right-to-know. The law has allowed the public access to summary pesticide  use information at the zip code level, and granted researchers access to confidential pesticide use for analysis. However, the proposed rules, written into the state’s Executive Budget proposal, dramatically restructures the state’s Pesticide Sales and Use Reporting Law, stipulating that the annual pesticide reporting summary release detailed sales – not use – data by county. Opponents of the change say that where things are sold are not necessarily where they are used. The inability to  identify where pesticides are used in the state will undercut the ability to track  associated environmental and health effects. “It will impede the public’s ability to learn about toxic chemical uses where they work, live and play,” said Peter Iwanowicz, executive director of Environmental Advocates of […]

(Beyond Pesticides, January 30, 2014) With the U.S. House of Representatives’ passage of the Agriculture Act of 2014 (commonly known as the Farm Bill) yesterday, conventional farming allies and chemical agribusiness dealt a dangerous blow to children’s health protections and offered up yet another reason for consumers everywhere to support organic. The behind-closed-door amendment to the Farm Bill that appeared in neither the pre-conference House or Senate-passed versions of the Bill available to the public, orders the U.S. Environmental Protection Agency (EPA) to ignore its ruling that levels of fluoride left in food treated with the toxic fumigant sulfuryl fluoride are unsafe for consumers everywhere, especially children and infants. Looking at the Numbers Under the Food Quality Protection Act (FQPA), a law designed to provide stronger protections for infants and children from pesticides, EPA must consider the aggregate dose that children receive from pesticide residues along with the other “nonpesticidal” sources. In the case of sulfuryl fluoride, a fumigant used in closed structures such as barns, storage buildings, commercial warehouses, ships in port, and railroad cars and thus also found on their stored contents like grains and other crops, this is an important consideration because other sources of fluoride abound […]
