(Beyond Pesticides, April 5, 2012) Newly published research has documented that widely used herbicides can adversely impact non-target invertebrate organisms and that endangered species face acute risk from such impacts. Researchers found that adult numbers of the Behr’s metalmark butterfly dropped by one-fourth to more than one-third when its larvae were exposed to herbicides applied in the vicinity of the butterfly’s preferred food source, the naked stem buckwheat plant. The results are especially disturbing because the Behr’s metalmark was being studied as a surrogate for the Lange’s metalmark butterfly, which shares the same habitat and feeding preference and whose population has shrunk from 2,300 in 1999 to less than 100 today. As a federally protected endangered species, the Lange’s metalmark could not be included in the experiment. Researchers concluded that inert ingredients in the herbicide formulations or indirect effects on food plant quality may be causing the increased butterfly mortality. The research was conducted at the 55 acre Antioch Dunes National Wildlife Refuge in Contra Costa County, CA, which is the only known habitat for the Lange’s metalmark. Refuge managers noticed that the naked stem buckwheat, which is native to the refuge and supports both species of butterflies, was being […]

(Beyond Pesticides, April 4, 2012) The world’s most popular weed killer can induce morphological changes in vertebrate animals, U.S. biologists studying its effect on amphibians say. University of Pittsburgh researchers have found that the weed killer Roundup, in sub-lethal and environmentally relevant concentrations, causes two species of amphibians to change their shape by interfering with the hormones of tadpoles and potentially many other animals. The study, “New effects of Roundup on amphibians: Predators reduce herbicide mortality; herbicides induce antipredator morphology” is the first to show that a pesticide can induce morphological changes in a vertebrate animal, biological sciences Professor Rick Relyea, PhD, said in a university release. The study was undertaken using simple created wetlands and introducing tadpoles from three species of amphibians —the leopard frog, American toad, and wood frogs. After three weeks, the tadpoles were examined. The impact of Roundup on the shape of tadpole tails was most noticeable in both the wood frog and leopard frog tadpoles. According to the study, “In wood frog and leopard frog tadpoles, Roundup induced relatively deeper tails in the same direction and of the same magnitude as the adaptive changes induced by dragonfly cues… [T]his is the first study to show […]

(Beyond Pesticides, April 3, 2012) Last week, the journal Science published two new studies linking neonicotinoid pesticide exposure to bee health. These two studies, one French, one British, add to a growing body of scientific literature and strengthen the case for removing pesticides toxic to bees from the market. The French study shows that pesticides interfere with honey bee brains, affecting their ability to navigate. The British research finds that pesticides prevent bumble bees from collecting enough food to produce new queens. These studies were released on the heels of an emergency legal petition by beekeepers and environmental groups, including Beyond Pesticides, that calls for the ban of the bee-killing pesticide clothianidin. Neonicitinoids are highly toxic to a range of insects, including honey bees and other pollinators. They are taken up by a plant’s vascular system and expressed through pollen, nectar and gutation droplets from which bees forage and drink. They are particularly dangerous because, in addition to being acutely toxic in high doses, they also result in serious sublethal effects when insects are exposed to chronic low doses, as they are through pollen and water droplets laced with the chemical as well as dust that is released into the […]

(Beyond Pesticides, March 30, 2012) Healthy Communities: the 30th National Pesticide Forum begins today, March 30, at Yale University in New Haven, CT and will continue through tomorrow evening. Walk-in registration starts at $35 ($15 for students) and includes all sessions, conference materials, and organic food and drink. There will be numerous speakers and workshops throughout the next two days focusing on issues such as the protection of Connecticut’s historic pesticide ban on school grounds, ensuring the health of pollinators in the face of toxic pesticides, and keeping the organic food and farming movement strong. Featured speakers include: Sandra Steingraber, PhD — Tonight’s keynote speaker (6:30-10:30pm) — An acclaimed ecologist and author, Dr. Steingraber explores the links between human rights and the environment, with a focus on chemical contamination. She takes a personal and scientific look at these issues and offers insights into how we can protect our environment and ourselves. She brings a clear, lyrical voice to the complex evidence of biology. The author of several books, including her latest Raising Elijah, Dr. Steingraber has been called “a poet with a knife” by Sojourner magazine, and received many honors for her work as a science writer. Her highly acclaimed […]

(Beyond Pesticides, March 28, 2012) The Canadian government is set to declare the bacteria killer found in many toothpastes, mouthwashes and anti-bacterial soaps as toxic to the environment, a move which could see the use of the chemical curtailed sharply in Canada. Triclosan, the chemical in question, has been linked to numerous human and environmental health effects and has been the subject of petitions calling for its ban from consumer products. Health Canada has been probing the effects of triclosan on the body’s endocrine system and whether the antibacterial agent contributes to the development of antibiotic resistance along with the effect of widespread use on the environment. The draft risk assessment finds triclosan to be toxic to the environment but but does not find enough evidence to say it is hazardous to human health. The formal proposal to list the chemical as toxic to the environment will be published Friday. Triclosan exploded on to the marketplace in hundreds of consumer products ranging from antibacterial soaps, deodorants, toothpastes, cosmetics, fabrics, toys, and other household and personal care products. While antibacterial products are marketed as agents that protect and safeguard against potential harmful bacteria, studies conclude that antibacterial soaps show no health […]

(Beyond Pesticides, March 27, 2012) On March 21, Beyond Pesticides joined beekeepers and environmental groups, Center for Food Safety and Pesticide Action Network North America in filing an emergency legal petition that calls on the Environmental Protection Agency (EPA) to suspend registration of Bayer’s controversial bee-killing pesticide, clothianidin. Because Congress has the authority to exercise oversight over federal agencies like EPA, the organizations are now calling on the public to ask Congress to protect honey bees and wild pollinators from clothianidin and other pesticides known to be toxic to bees. Bees and other pollinators are still dying off at catastrophic rates —commercial beekeepers lost an average of 36% of their hives last year, according to USDA. Honey bees pollinate one in every three bites of our food and, as indicator species, they serve as sentinels whom we ignore at our peril. As the public debate over causes of Colony Collapse Disorder (CCD) —a syndrome in which bees seemingly abandon their hives— carries on in the media, more and more new science has shown that neonicotinoid pesticides are indeed a critical piece of the puzzle. Neonicotinoids like clothianidin may not be the sole cause of CCD, but they are making our […]

(Beyond Pesticides, March 26, 2012) Organic and sustainable agriculture advocates achieved a milestone victory on March 23 when a federal judge ruled that the U.S. Food and Drug Administration (FDA) must act promptly to determine whether to ban subtherapeutic uses of antibiotics in livestock. The ruling is the latest step in a regulatory process that began in 1977 when FDA determined that feeding livestock certain antibiotics used in human medicine, including penicillin and tetracyclines, could promote antibiotic-resistant bacteria capable of infecting people. Despite its legal obligation to act, FDA has delayed taking action for over three decades and in late 2011 even terminated the original rulemaking process in an attempt to close the matter. In last week’s ruling, Judge Theodore Katz ordered FDA to notify drug manufacturers of its intention to revoke approval for uses of penicillin and tetracycline to promote growth in livestock. FDA must schedule hearings to let drug manufacturers make their case, and if the drug manufacturers cannot prove that the use of these antibiotics in livestock feed is safe, the agency must withdraw approval. The judge’s decision makes it clear that the voluntary approach FDA proposed last year when terminating the rulemaking process does not satisfy […]

(Beyond Pesticides, March 23, 2012) In a victory for environmentalists and farmworkers, manufacturers of the controversial and highly toxic fumigant methyl iodide announced it will cease selling its products containing the chemical in the U.S. market earlier this week. Representatives from the Tokyo-based company, Arysta LifeScience say that the decision was made as a part of an internal review and based on its economic viability in the U.S.; however, the company will still continue to sell methyl iodide products in other countries. “Today I’m really happy. It feels like someone finally listened to us about something really important.” Gabriela Rincon, told the Los Angeles Times. Ms. Rincon is the daughter of farmworkers who pick strawberries in the Salinas area in California. Methyl iodide causes late term miscarriages, contaminates groundwater and is so reliably carcinogenic that it’s used to create cancer cells in laboratories. It is on California’s official list of known carcinogenic chemicals and has been linked to serious risks in reproductive and neurological health. The pesticide poses the most direct risks to farmworkers and those in the surrounding communities because of the volume that would need to be applied to fields and its tendency to drift off site through […]

(Beyond Pesticides, March 22, 2012) Yesterday, commercial beekeepers and environmental organizations filed an emergency legal petition with the U.S. Environmental Protection Agency (EPA) to suspend use of a pesticide that is linked to honey bee deaths, urging the agency to adopt safeguards. The legal petition, which specifies the pesticide clothianidin, is supported by over one million citizen petition signatures, targets the pesticide for its harmful impacts on honey bees. “EPA has an obligation to protect pollinators from the threat of pesticides,” said Jeff Anderson of California Minnesota Honey Farms, a co-petitioner. “The Agency has failed to adequately regulate pesticides harmful to pollinators despite scientific and on-the-ground evidence presented by academics and beekeepers.” Over two dozen beekeepers and beekeeper organizations from across the country, from California and Minnesota to Kansas and New York, filed the legal petition with the EPA today. Many of these family-owned beekeeping operations are migratory, with beekeepers traveling the country from state-to-state, during different months of the year to providing pollination services and harvesting honey and wax. And they are concerned about the continued impacts on bees and their beekeeping operations, which are already in jeopardy. “The future of beekeeping faces numerous threats, including from clothianidin, and […]

(Beyond Pesticides, March 21, 2012) A half-century after California officials discovered that large amounts of the pesticide DDT had been discharged into a San Francisco Bay canal, the chemical is still poisoning fish and posing a threat to human health despite numerous cleanup attempts. After years of limited success with clean-up, the U.S. Environmental Protection Agency (EPA) has launched a three-year plan to pinpoint the cause of continuously high DDT levels and engage the surrounding community in cleanup and education efforts. The former plant and the adjacent canal, called the Lauritzen Channel, an inlet of the greater San Francisco bay, is one of the most polluted places in the nation. DDT levels have not decreased in the channel even after numerous dredging and other mitigation measures. In fact concentrations have increased. By 2011, DDT concentrations exceeded 1994 levels and some fish have DDT levels in their tissues hundreds of times higher than their counterparts in the rest of the San Francisco Bay. EPA said earlier this month it is launching a three-year plan to help unravel the mystery of why cleanup attempts are failing, and will work with the city to increase awareness among anglers who rely on bay fish […]

(Beyond Pesticides, March 19, 2012) A group of 22 prominent entomologists has submitted formal comments to the U.S. Environmental Protection Agency (EPA) casting doubt on the future viability of certain varieties of genetically engineered (GE) corn. The entomologists, including researchers from land grant institutions in the Corn Belt and the U.S. Department of Agriculture’s Agricultural Research Service, cite increasing evidence that the western corn rootworm is developing resistance to a toxin derived from Bacillus thuringiensis (Bt), which is inserted into seeds. Bt is a naturally occurring soil bacterium that when used in non-genetically engineered forms is an important biological pesticide for organic and sustainable farmers. The entomologists identify significant flaws in current practices for managing insect resistance to Bt corn and caution that failure to implement a series of alternative measures based on an integrated pest management (IPM) approach would result in all forms of Bt losing its effectiveness. The entomologists’ comments were cited recently in published research documenting the first field-evolved resistance of the western corn rootworm to certain Bt strains. They draw a connection between this research and field reports of greater than expected rootworm damage (an indication of emerging resistance) first observed in 2009. Detections of greater […]

(Beyond Pesticides, March 16, 2012) A report published online this week in the journal Endocrine Reviews documents extensive scientific research showing that endocrine disrupting chemicals, or endocrine disruptors, can be toxic to humans even in minutely small doses. The report, three years in the making, was published Wednesday by a team of 12 scientists who study hormone-altering chemicals. Authors include the University of Missouri’s Frederick vom Saal, PhD., who has linked low doses of bisphenol A (BPA) to a variety of effects, Theo Colborn, PhD., who is credited with first spreading the word about hormone-disrupting chemicals in the late 1980s, and University of California at Berkeley’s Tyrone Hayes, PhD., who has documented the effects of the pesticide atrazine on frogs. Drs. Colborn, Hayes, and vom Saal are all former speakers at the National Pesticide Forum. One of the reporrt’s authors is Pete Myers, PhD, the founder of Environmental Health News and chief scientist of Environmental Health Sciences. Dozens of substances that can mimic or block estrogen, testosterone and other hormones are found in the environment, the food supply and consumer products, including plastics, pesticides and cosmetics. One of the biggest, longest-lasting controversies about these chemicals is whether the tiny doses […]

(Beyond Pesticides, March 9, 2012) With Members of Congress attempting to gut pesticide protections from the Clean Water Act and state legislators threatening to repeal Connecticut’s historic pesticide ban on school grounds, environmentalists from the Northeast and beyond are joining with researchers, authors, beekeepers, organic business leaders, elected officials, and others to discuss strategies for protecting health and the environment. Healthy Communities: the 30th National Pesticide Forum will take place March 30-31 at Yale University in New Haven, CT. Register online. Fees start at $35 ($15 for students) and include all sessions, conference materials, and organic food and drink. A limited number of partial scholarships are available, contact Beyond Pesticides for details. Conference Highlights: Pesticide-Free Lawns and Landscapes With the Connecticut General Assembly’s considering legislation that would repeal the state’s ban on toxic pesticide use on school grounds by replacing it with a weak “integrated pest management” (IPM) system, this issue will be a central theme at the conference. Speakers on this topic include: Warren Porter, PhD, professor of Zoology and Environmental Toxicology at the University of Wisconsin at Madison with expertise in lawn chemicals, especially low doses and mixtures; Chip Osborne, national organic turf expert and president of Osborne […]

(Beyond Pesticides, March 7, 2012) Researchers in Europe have found that the insecticide Bacillus thuringiensis (Bt) when incorporated into genetically engineered (GE) plants, and the herbicide glyphosate, used widely with GE glyphosate-tolerant crops, are toxic to human cells, disputing commonly held assertions by regulators and the chemical industry that these substances are entirely harmless to humans. The research team, led by scientists at the University of Caen in France, says that at very high doses Bt is toxic to human cells, and glyphosate, when formulated as the product Roundup, manufactured by Monsanto Co., damages human cells, even in extremely low doses. The findings of the study have been published online in the Journal of Applied Toxicology. Bt is a commonly used least-toxic insecticide which is available in several different strains, each toxic to a different range of insects. The substance is a naturally occurring soil bacterium that has been harnessed and enhanced to make it more effective as a pesticide product. Crops such as corn and cotton are also often genetically engineered (GE) to produce Bt proteins so that insects are infected with the toxin when they feed on the plant. The French researchers suggest that it may be this […]

(Beyond Pesticides, March 6, 2012) New research conducted in New Bedford, Massachusetts suggests that organochlorine chemicals, which were first linked to learning problems in children more than two decades ago, may play a role in attention-deficit hyperactivity disorder (ADHD), especially in boys. Previous research has reported associations between organochlorines and ADHD-related behaviors, but this research found sex-specific effects in children born to mothers who lived near the contaminated harbor and dumpsites in low-income communities. This study adds to a growing body of literature associating learning disorders with prenatal chemical exposures. According to the study, Neuropsychological Measures of Attention and Impulse Control among 8-Year-Old Children Exposed Prenatally to Organochlorines, boys who were exposed to higher levels of the organochlorines -polychlorinated biphenyls (PCBs) and DDE (a metabolite of DDT)- in the womb scored lower on focus and concentration tests, which indicates they are more likely to have attention problems often related to ADHD. In the study, umbilical cord blood was collected from 788 newborns born between 1993 and 1998 from four towns near New Bedford Harbor, Mass., to see what they were exposed to in the womb. Roughly eight years after they were born, almost 600 of these children underwent two tests. […]

(Beyond Pesticides, February 28, 2012) A study by researchers at the University of Padova in Italy and published in the journal Environmental Science and Technology has confirmed the findings of previous research showing that honey bees are exposed to toxic neonicotinoid insecticides during spring seed planting. Neonicotinoids are known to be highly toxic to honey bees and, yet, are used on millions of acres through North America every year. These findings lend even greater urgency to the need to take these chemicals off the market and ensure the continued survival of honey bees and the essential pollination services that they provide for our food system. Neonicotinoids, including clothianidin, imidacloprid, and thiamethoxam, are most commonly applied by coating crop seeds with the chemical. When these treated seeds are planted, the chemical becomes part of the plants vascular system and stays in the plant for the duration of its lifetime, expressing itself in the pollen. Previously, it had been thought that bees were only exposed to these chemicals through pollen and water droplets from treated plants, which would occur later in the season once the plants had grown and bloomed. However, the Italian study shows that bees are actually exposed to high […]

(Beyond Pesticides, February 27, 2012) For the first time since its initial evaluation almost 30 years ago, the U.S. Environmental Protection Agency (EPA) has revised, despite objections from the chemical industry, its dioxin exposure assessment for acute human health risks –setting an “acceptable” level of 0.7 picograms per kilogram per day. Environmentalists said EPA’s estimated average exposure, currently at 0.5—3 picograms per kilogram per day, puts a portion of the population above the EPA danger threshold. Work on updating the health assessment began in 1991 and was partially completed with the February 12 release of the Final Non-Cancer Dioxin Science Assessment. While EPA characterized the findings as showing that “generally, over a person’s lifetime, current exposure to dioxins does not pose a significant health risk,” the Assessment establishes a daily “acceptable” exposure threshold, or reference dose, which the agency says is comparable to levels which people routinely experience. Beyond Pesticides reviewed the underlying chemistry and historical exposure patterns, including diet and human health effects of dioxins, in a recent Daily New blog entry leading up to the Assessment’s release. EPA’s decision to adopt its recommended reference dose of 0.7 picograms of dioxins per kilogram of body weight per day that […]

(Beyond Pesticides, February 24, 2012) On Wednesday, February 22, the Connecticut General Assembly’s Planning and Development Committee held a hearing to consider a bill that would repeal the state’s ban on toxic pesticide use on school grounds by allowing their use as part of a so-called “integrated pest management” (IPM) system. If you live in Connecticut, you can take action to fight this bill and preserve the health of school children. Current state law, adopted in 2005 and amended in 2007 and 2009 to cover facilities from day care centers up through grade 8, prohibits pesticides on playgrounds and playing fields at schools (except under emergency situations), allowing instead for non-toxic pest and fertility management. The bill currently under consideration, HB 5155, would repeal the ban, making pesticide use allowable as part of an IPM program as defined by any number of a range of bureaucratic offices. Although IPM can be a helpful tool in the transition from a pesticide-intensive to a non-toxic management system, it makes no sense to weaken an already strong standard aimed at protecting the health of children. The effort to adopt such a system through passage of HB 5155 is being led by public works […]

(Beyond Pesticides, February 22, 2012) Researchers have found high levels of endosulfan, a highly toxic organochlorine pesticide, in the bone marrow of children, including those suffering from hematological malignancies (blood cancers) in areas using the pesticide. Children who have endosulfan in their bone marrow have 7.5 times more risk of developing blood-related cancer compared to those with no detectable pesticide in the bone marrow. While the findings are based on research in India, the insecticide is still used in the production of dozens of crops in the U.S., even though EPA found that exposure to the chemical exceeds the agency’s acceptable risk criteria and announced in 2010 a six-year negotiated phase-out plan with industry that stretches from 2012 to 2016. Following a lawsuit filed against the U.S. Environmental Protection Agency (EPA) in 2008, which cited EPA’s glaring omission in not considering risks to children, EPA announced in 2010 that it would, instead of stopping exposure to a known hazard immediately, phase-out over a six year period all uses of endosulfan in the U.S. Rather than regulating a stop use, EPA astounded many in the environmental and public health community by negotiating a long phase-out agreement with manufacturers that allows some […]

Beyond Pesticides, February 21, 2012) Last week, the Monterey County Board of Supervisors urged California Governor Jerry Brown to reconsider the state’s approval of the carcinogenic fumigant methyl iodide. Monterey County, one of the largest agricultural counties in California, joins Santa Cruz County in mounting pressure to re-examine the controversial decision to approve the toxic chemical as a replacement to the ozone-depleting methyl bromide. This news comes at the heels of the announcement earlier this month that Gov. Brown appointed Brian Leahy, a former organic farmer and the former assistant director at the California Department of Conservation, to head the state Department of Pesticide Regulation (DPR). According to The Californian, agricultural interests present asked County Supervisors to take no action. However, with dozens of local farm workers in attendance pleading their case, the board passed the resolution on a 4-1 recommending that Gov. Brown take another look at the fumigant. Methyl iodide is known to cause miscarriages, thyroid dysfunction, and cancer, and is applied to crops like strawberries and peppers. It was approved by California state pesticide regulators in December as an alternative to methyl bromide, an ozone-depleting chemical being phased out under international treaty. In 2007, EPA fast-tracked the […]

(Beyond Pesticides, February 17, 2011) Beyond Pesticides is urging the U.S. Environmental Protection Agency (EPA), during a public comment period (closing February 23) on its review of the neonicotinoid pesticide, clothianidin, to take swift action to cancel the chemical’s registration. Groups are joining together with comments to EPA, citing the extensive science that shows clothianidin’s toxic effects on honey bees. Beyond Pesticides has drafted comments that it will submit to EPA outlining serious concerns regarding clothianidin. The agency is accepting public comments through February 21, 2012. Tell EPA that because this pesticide is toxic to honey bees and wild pollinators, and has not been properly evaluated in field studies as required it should be banned. Submit comments directly to the EPA docket or sign-on to Beyond Pesticides’ comments. Clothianidin is in the neonicotinoid family of systemic pesticides, which are taken up by a plant’s vascular system and expressed through pollen, nectar and gutation droplets from which bees forage and drink. Scientists are concerned about the mix and cumulative effects of the multiple pesticides bees are exposed to in these ways. Neonicotinoids are of particular concern because they have cumulative, sublethal effects on insect pollinators that correspond to symptoms of honey […]

(Beyond Pesticides, February 16, 2012) Newly released data indicates that more than 40% of American farmers who planted certain varieties of genetically engineered (GE) corn in 2011 failed inspections to verify compliance with mandatory management practices to prevent insect resistance. The farmers involved planted corn varieties that are genetically engineered to express toxins that kill western rootworm. The toxins are derived from Bacillus thuringiensis (Bt), a naturally occurring soil bacterium that when used in non-genetically engineered forms is an important pesticide for organic and sustainable farmers. The non-compliant farmers were specifically cited for failure to establish adequate refuges of non-Bt corn on their farms that the U.S. Environmental Protection Agency (EPA) has determined are necessary to prevent the western rootworm from developing resistance to all forms of Bt. Originally reported on February 9, the results are derived from GE Bt seed suppliers who are required to report refuge data to EPA. As a condition of registering Bt seed varieties as pesticides, EPA requires that farmers using them also plant an appropriately-sized refuge of non-Bt varieties adjacent to the genetically engineered crop. In theory, western rootworms that develop resistance to Bt through constant exposure to the toxins in the genetically engineered […]

(Beyond Pesticides, February 14, 2012) A French court has found U.S. chemical giant Monsanto Co. guilty of pesticide poisoning in the case of a French farmer who became ill after exposure to one of the company’s herbicides, according to Reuters. The case is significant in that it sets precedent for other cases alleging pesticide poisoning or negligence in reporting of potential effects on human health resulting from pesticides. The court has said it will seek an expert opinion regarding the farmer’s losses in order to determine the appropriate amount of damages he should be rewarded. The case stems from an incident in which the farmer, Paul Francois, inadvertently inhaled Monsanto’s Lasso pesticide when cleaning his sprayer tank on his farm in southern France in 2004. He then began experiencing memory loss, headaches, and stammering, among other neurological problems. This led to his decision to file suit against Monsanto, asserting that the company did not provide adequate warnings on the product label that would indicate these symptoms could result from exposure. The court agreed with Mr. Francois, stating that, “Monsanto is responsible for Paul Francois’s suffering after he inhaled the Lasso product … and must entirely compensate him,” according to Agence […]
