Neonicotinoid Insecticides Deprive Fish of Food in Lake Shinji, Japan

(Beyond Pesticides, November 6, 2019) Between 1981 and 1992, Japanese fishers annually reaped an average of 240 tons of smelt from Lake Shinji. After 1993, their nets turned up about 22 tons ‚Äď a 90% drop in their yield. Eel catches dropped by 74%. New research, published in the journal Science, implicates the introduction of neonicotinoids to the abutting watershed in the decimation of these aquatic populations, stating, ‚ÄúIn Lake Shinji, neonicotinoids indirectly reduced fishery yields by decreasing the abundance of invertebrates that serve as food for smelt and eels.‚ÄĚ Researchers analyzed decades of data on zooplankton, midges, and water quality as well as annual fishery yields of eel and smelt spanning from 1981-2014. Zooplankton biomass, an important fodder for smelt, plummeted from 108 ¬Ķg C L‚ąí1 to 18.2 ¬Ķg C L‚ąí1 after imidacloprid was introduced for use on rice paddies in May of 1993. Midges (Cyathura muromiensis) that were found in abundance in 1982 totally disappeared from all sample sites by 2016. While the smelt and eel populations drastically declined, the authors note that icefish, which eat a more diversified diet, were not impacted. Though researchers considered the possibilities of other influencing factors such as invasive species, hypoxia, and […]

Take Action: Tell University of California to Stop Hazardous Pesticide Use and Adopt Organic Land Management

(Beyond Pesticides, October 27, 2019)¬†The spraying of toxic herbicides for weed control on campuses exposes students, workers and the general public to chemicals linked to health problems such as cancer and¬†reproductive issues. Any day now, the University of California system will decide whether or not to continue using glyphosate and other toxic herbicides ‚ÄĒ including Roundup ‚ÄĒ on their campuses. The University of California¬†temporarily banned the use of cancer-causing glyphosate, the main ingredient in Roundup, but the¬†ban doesn’t stop the UC system from using other dangerous herbicides. Student activists are asking UC to¬†commit to transitioning to¬†all organic land care maintenance on all University of California campuses by 2025. This could be an opportunity for the University of California, which prides itself on its commitment to sustainability, to join other universities such as Harvard, the University of Colorado at Boulder, Yale, University of Pennsylvania, and others as a national leader in the field. Tell University of California President Napolitano to issue a full, permanent ban on toxic herbicides and shift the UC land care system to organic! Message to University of California President First of all, I would like to thank you for temporarily suspending the use of glyphosate-based herbicides on […]

Study Adds to Evidence that Organic Fruit Consumption Leads to Lowers Levels of Pesticide Contamination in Children, Pregnant Women

(Beyond Pesticides, October 24, 2019) Fish and fruit are undoubtedly healthy foods, but modern-day contamination is leading scientists to caution pregnant mothers and young children to stick within current dietary guidelines, or switch to organic, in order to avoid adverse health effects. This new public health message is based on research published in the journal Environmental Health Perspectives by scientists from University of Southern California (USC) and several European Countries, finding that overconsumption of fish and fruits leads to higher levels of contamination with toxic persistent chemicals. ‚ÄúDuring gestation and early development, the fetus and the child, respectively, are vulnerable to the effects of environmental chemicals, said Lida Chatzi, MD, associate professor of preventive medicine at the Keck School of Medicine of USC. ‚ÄúA balanced diet during these periods is also critical for optimal nutritional status, but what to eat, and how much, are critical questions.‚ÄĚ Scientists studied a cohort of 1,288 children (between 6 and 11 years) and 818 pregnant mothers from six European countries, who were provided questionnaires to assess their weekly diet. Blood levels of a range of environmental toxicants, including organochlorine compounds like PCB, PFHSs, PFOS, PFOA, pesticides like DDT and DDE, and heavy metals including […]

Take Action: Remove Known Carcinogens from Organic

(Beyond Pesticides, October 20, 2019)¬†USDA‚Äôs National Organic Standards Board (NOSB) should remove nonorganic celery powder from the National List of Allowed and Prohibited Substances for use in organic food production. It has been long-established that nitrates and nitrites, used to prevent bacterial growth in processed meats, react with protein to create nitrosamines, which are widely considered to be possible carcinogens. The World Health Organization considers processed meat ‚Äúa known carcinogen.‚ÄĚ Tell NOSB to remove carcinogenic¬†nonorganic celery powder from organic processed meat. For too long the meat industry, including organic processors, have engaged in a form of subterfuge by being able, and in fact required, to label meat preserved with celery powder as ‚Äúno nitrates or no nitrites added‚ÄĚ or ‚Äúuncured.‚ÄĚ The use of conventional celery powder, with amped up applications of synthetic nitrogen fertilizer, creates the same functional and biological impacts as synthetic nitrates/nitrates as a meat preservative. The federal laws governing organics are clear. To legally use a synthetic compound, or a natural or agricultural material that is not certified organic, in the production of certified organic product, it must appear on the list of approved substances. And to do so, proposed materials must not damage the environment or […]

Despite Damning Scientific Evidence, EPA Dismisses Link Between Parkinson’s and Exposure to the Herbicide Paraquat

(Beyond Pesticides, October 17, 2019) The U.S. Environmental Protection Agency (EPA) is downplaying the connection between exposure to the herbicide paraquat and the development of Parkinson‚Äôs disease, per registration review documents released by the agency this week. Although unsurprising given the current administration‚Äôs track record of defending some of the most heinous chemicals still on the market, the review nonetheless marks a low point for scientific integrity within EPA‚Äôs Office of Pesticide Programs, according to advocates. Health and environmental advocates have already discounted EPA‚Äôs industry-biased review, and are instead pushing hard for Congressional action ‚Äď namely HR 3817, the Protect Against Paraquat Act, introduced by Congresswoman Nydia Velazquez (D-NY). Under federal law, pesticides are required to undergo reevaluation every 15 years. Paraquat is a potent restricted use herbicide, not available to be applied by residential users, but permitted for use on multiple agriculture crops. Over the last decade, independent peer-reviewed scientific studies have repeatedly found strong associations between paraquat to the development of Parkinson‚Äôs disease. Many of these studies have been covered in Beyond Pesticides‚Äô Daily News or are recorded in the Pesticide-Induced Diseases Database. In response to this growing body of literature, EPA conducted an epidemiological evaluation of published […]

Take Action: EPA Must Evaluate the Effects of Multiple Pesticide Ingredient Use and Exposure

(Beyond Pesticides, October 15, 2019)¬†EPA is requesting comment on its proposal to require data that will help it determine synergistic effects of some pesticides. EPA has received on a pressure on a number of fronts, including a report by the Center for Biological Diversity, a report by its own Inspector General, a letter from 35 Congressional Representatives, and research pointing to the unavoidability of synergistic effects‚ÄĒthe chemical combinations that cause greater effects when mixed together than the sum of the individual chemical effects. Despite all of the evidence that synergism is the rule rather than the exception, EPA‚Äôs consideration focuses on a narrow range of cases in which pesticide product patents make claims of synergy. Tell EPA to always investigate synergy and to determine need for pesticides. One such product is Dow‚Äôs Enlist Duo, which combines glyphosate and 2,4-D in an attempt to overcome weed resistance. The focus on products and tank mixes where synergism is a selling point brings to light the fact that as a rule, EPA does not request efficacy data in registering pesticides not intended to protect public health. Thus, although required by law to weigh pesticide risks and benefits, EPA rarely has data to make […]

Glyphosate, When Combined with Other Stressors, Results in Breast Cancer Development

(Beyond Pesticides, October 9, 2019) Pesticide industry propaganda promoting the safety of glyphosate-based herbicides took another hit last month, as a study published by an international team of researchers found the chemical had the potential to induce breast cancer when combined with other risk factors. The study, Glyphosate Primes Mammary Cells for Tumorigenesis by Reprogramming the Epigenome in a TET3-Dependent Manner, led by scientists from Indiana‚Äôs Purdue University and the Institut National de la Sant√© et de la Recherche M√©dicale (INSERM)/Institut de Canc√©rologie de L‚ÄôOuest (ICO) in Nantes, France, provides an important new lens through which to view pesticide-induced cancer development. ‚ÄúThis is a major result and nobody has ever shown this before,‚ÄĚ says Sophie Leli√®vre, PhD,¬†a professor of cancer pharmacology in Purdue‚Äôs¬†College of Veterinary Medicine and co-leader of IBCN.¬†‚ÄúShowing that glyphosate can trigger tumor growth, when combined with another frequently observed risk, is an important missing link when it comes to determining what causes cancer.‚ÄĚ To make their determination, scientists exposed human breast cells low levels of glyphosate every three to four days over the course of 21 days. A control group was also dosed with a known cancer-promoting peptide. Glyphosate caused the same changes to exposed cells as […]

Banana Workers Made Sterile from Pesticide Sue Dow in France

(Beyond Pesticides, October 7, 2019)¬†Central American agricultural workers, exposed in the 1970s and early 1980s to a highly toxic pesticide, subsequently began suing manufacturers in the mid-1980s, with mixed success. Now, some of those workers have stepped up their game: they have brought suit against three big agrochemical industries in France to try to recover hundreds of millions of dollars in damages awarded to them by Nicaraguan courts, but never paid. As reported by The New York Times, ‚Äúthe case could set a legal precedent and lead to more lawsuits in France for harm done in other countries by the pesticide Nemagon.‚ÄĚ Farmworkers in Nicaragua, Guatemala, Costa Rica, Ecuador, Panama, the Philippines, West Africa, and the U.S. were exposed to the highly toxic, brominated organochlorine pesticide ingredient, DBCP (dibromochloropropane), from the 1960s until cessation of its use, which has varied from country to country. DBCP was sold in the pesticide products Nemagon and Fumazone as a soil fumigant and nematocide on banana plantations and other crops across Central America (especially), in western Africa, and in Hawaii. As acknowledged by the Environmental Protection Agency (EPA), DBCP has multiple adverse health impacts: decreased sperm production and mobility, disturbed estrous cycles, reduced phagocytosis […]

Common Fungicides’ Use Leads to Algae Blooms

(Beyond Pesticides, October 1, 2019) Commonly used fungicides induce trophic cascades that can lead to the overgrowth of algae, according to research published in the journal Chemosphere. While the current process for regulating pesticides in the U.S. focuses on the acute toxicity of pesticides, and may consider some chronic impacts, real world complexities as described in the current study are not reviewed. This gap in our assessment can lead to significant adverse effects not just on individual species, but entire ecosystems. Researchers investigated how fungal parasites known as chytrids control the growth of phytoplankton. While some strains of chytrids are notorious for their impact to frog species, some do in fact provide important stopgaps within ecosystems. “By infecting cyanobacteria, parasitic fungi limit their growth and thus reduce the occurrence and intensity of toxic algal blooms,” says IGB researcher Ramsy Agha, PhD, co-author the study. “Whereas we usually perceive disease as a negative phenomenon, parasites are very important for the normal functioning of aquatic ecosystems and can — as in this case — also have positive effects. Pollution by fungicides can interfere with this natural process,” the researcher adds. The agricultural fungicides tebuconazole and azoxystrobin were tested on chytrid-infected toxic bloom-forming […]

Mysterious ‚ÄúHavana syndrome‚ÄĚ Linked to Neurotoxic Pesticide Exposure

(Beyond Pesticides, September 24, 2019) In 2016, Canadians and Americans residing in Havana reported symptoms of headaches, dizziness, nausea. They described hearing strange buzzing and high-pitched sounds ‚Äď some woke in the middle of the night fumbling for alarm clocks that were not going off. Media used the term ‚ÄúHavana syndrome‚ÄĚ to describe the illness. Diplomats, scared by symptoms that seemed to only hit them in their hotel rooms or at home, speculated that a sonic weapon was being used against them. The Trump administration accused Cuban leaders of misconduct and removed all but essential employees. Later, some suspected that the diplomats could have experienced ‚Äúmass hysteria.‚ÄĚ A new Canadian study provides a more likely explanation to this mysterious illness that impacted diplomats in Havana: neurotoxic pesticide exposure. Researchers conducted testing on 14 individuals who had resided in Havana and a control group of 12 that had never lived there. Some of the experimental group had been recently exposed while others, tested 19 months after their return, were classified as ‚Äúremotely exposed.‚ÄĚ Tests included brain imaging and self-reported symptom questionnaires. They analyzed blood samples for routine biochemistry, kidney, liver, and metabolic functions. Individuals that showed symptoms of brain injury went […]

Toxic Pesticides Found, Again, to Yield No Increase in Productivity or Economic Benefit for Farmers

(Beyond Pesticides, September 20, 2019) The actual utility of pesticides to achieve their purported goals is an under-recognized failing of the regulatory review of pesticide compounds for use. A study published in Scientific Reports now exposes the faulty assumptions underlying the use of neonicotinoids ‚ÄĒ the most widely used category of insecticides worldwide. The study demonstrates that use of neonicotinoids (neonics) to treat seeds ‚ÄĒ a very common use of these pesticides ‚ÄĒ actually provides negligible benefits to soybean farmers in terms of yield and overall economic benefit. The U.S. Environmental Protection Agency (EPA) should take notice, and consider that efficacy ought to have a role in the agency‚Äôs evaluation of pesticides for registration. Neonicotinoids are systemic pesticides that move through a plant‚Äôs vascular system and are expressed in pollen, nectar, and guttation droplets (drops of sap exuded on the tips or edges of leaves of some vascular plants). They can also persist in the environment ‚ÄĒ in soil and water ‚ÄĒ for extended periods. Neonics are applied to seed, as well as to crop soils and to plant foliage. Corn and soybean seed treatments represent the largest uses of neonics in the U.S.: for somewhere between 34% and 50+% […]

Study Finds Neonics Result in the Silent Demise of Songbirds

(Beyond Pesticides, September 17, 2019) The poisonous farm fields migratory birds forage on during their journey reduce their weight, delay their travel, and ultimately jeopardize their survival, according to new research published in the journal Science. ¬†Like their effects on pollinator populations, neonicotinoid insecticides generally are not killing migratory songbirds outright, but instead precipitating a cascade of sublethal impacts that reduces their fitness in the wild. As the authors told Environmental Health News, the study is a call not simply to ban neonics or one class of chemical, but to change the entire farming system toward more sustainable bird and bee-friendly practices. Using new technology, this study was not only able to dose wild-caught songbirds (white-crowned sparrows), but also track their migration route using automated telemetry. Apart from the control group that received no pesticide exposure, sparrows were treated at levels well below the median lethal dose (3% of the lethal dose in the ‚Äėlow‚Äô exposure group and 10% within the ‚Äėhigh‚Äô exposure group), and permitted to continue on their migratory path. These are exposure amounts similar to a songbird accidentally ingesting a few treated seeds, according to the study. Within six hours, both the ‚Äėlow‚Äô and ‚Äėhigh‚Äô exposure group […]

Herbicide Drift from Agricultural Use Found to Harm Bird Habitat

(Beyond Pesticides, September 13, 2019)¬†A study on the use of the herbicide dicamba‚Äôs off-target effects finds broad impacts, in both geographic spread and the variety of affected species, with use of the weed killer on Arkansas cropland putting birds at risk in agricultural landscapes. Audubon of Arkansas is reporting results of its community science dicamba monitoring project, conducted under the direction of Bird Conservation Director Dan Scheiman, PhD, and launched in late spring 2019. The project monitored dicamba symptomology in species on municipal, state, and federal lands, where dicamba was not applied, but where its impacts were nonetheless detected. Arkansas Audubon ‚Äúpredicts that in a landscape full of GMO crops [genetically modified organisms] (on which dicamba is typically used), the atmospheric loading of volatile dicamba could be enough to cause landscape scale damage to our state natural areas, wildlife management areas, national wildlife refuges, family farms, and the wildlife they harbor.‚ÄĚ Dicamba herbicides are volatile compounds used to control broadleaf weeds ‚ÄĒ especially on fields of GMO soybean and cotton crops that have been genetically engineered for resistance to dicamba. These herbicides damage non-GMO crops and native plants well beyond intended application areas. (In 2017,¬†more than 3 million acres of […]

Germany Moves to Phase-Out Glyphosate/Roundup; EPA Unmoved

(Beyond Pesticides, September 11, 2019)¬†Germany is the latest entity to take action on getting glyphosate-based pesticides out of the marketplace. Chancellor Angela Merkel has announced that, beginning in 2020, the country will phase out herbicides that contain glyphosate by the end of 2023. The phase-out will occur through a series of scheduled reductions in amounts allowed for use, with a goal of a 75% reduction over the next four years. The announcement comes after ‚Äúnation-wide protests and demands from [Merkel‚Äôs] junior coalition partner, the Social Democrats, for more decisive action on environmental issues.‚ÄĚ This action stands in telling contrast to the U.S. Environmental Protection Agency‚Äôs (EPA‚Äôs) repeated failures to protect people, ecosystems, and our food supply, from this toxic compound. The German government also plans to oppose any European Union (EU) request for renewal of licensing of these herbicides, according to the environment ministry. Bayer AG, maker of glyphosate-based herbicides and owner of original manufacturer Monsanto, has pushed back, saying that the government is ‚Äúgetting ahead of itself‚ÄĚ by banning glyphosate-based herbicides prior to any decision by the relevant EU authority, and that EU laws disallow unilateral decisions by member states.

Health and Environmental Groups Call on EPA to Revoke Glyphosate’s Registration

(Beyond Pesticides, September 4, 2019) Sixteen organizations representing health, environmental, farmer, and farmworker communities joined together yesterday to call on EPA to remove glyphosate from the marketplace. The groups cite a combination of high-profile lawsuits, environmental impacts, increasing reports of weed resistance, and growing public concern over the health effects of glyphosate in their comments on EPA‚Äôs interim reregistration review decision for the chemical. The comments warn that EPA is at risk of damaging the public‚Äôs trust in the agency‚Äôs review process for toxic pesticides. ‚ÄúEPA‚Äôs myopic review and response to the dangers posed by glyphosate does a disservice to American farmers, farmworkers, and commercial landscapers wishing to use least-toxic products that do not put them at risk of health impacts, and consumers aiming to make the safest choice in regards to what to feed their family and how to manage their yards,‚ÄĚ the comments read. The document likewise replies to EPA‚Äôs attacks against the World Health Organization‚Äôs International Agency for Research on Cancer (IARC), which determined glyphosate to be a probable carcinogen based on sufficient evidence of carcinogenicity in experimental organisms. EPA has indicated that its process for evaluating glyphosate, ‚Äú‚Ķis more transparent than IARC‚Äôs process‚ÄĚ and that IARC‚Äôs […]

Brain Function Damage from Exposure to Organophosphate Pesticides, including Chlorpyrifos, Documented with Imaging

(Beyond Pesticides, August 30, 2019) The indictment of organophosphate pesticides gained more traction with the publication, in the Proceedings of the National Academy of Sciences, of a new research study out of the University of California, Berkeley. The research, among the first to use advanced brain imaging to assess cortical activation, shows altered brain activity, during tasks that call on executive function, in teenagers from California‚Äôs Salinas Valley (the site of significant organophosphate use) whose mothers were exposed prenatally. The UC Berkeley study underscores the slow-motion calamity of the Trump administration Environmental Protection Agency‚Äôs (EPA‚Äôs) failure to ban the use of this class of pesticides, and of chlorpyrifos in particular, which compounds carry extreme risks for children. The effects of this prenatal exposure continue to unfold during children‚Äôs critical developmental periods. Researchers used fNIRS (functional near-infrared spectroscopy) imaging to monitor blood flow in the brains of the teens, 15‚Äď17, born and raised in the Salinas Valley. They used data from the California¬†Pesticide Use Reporting¬†program (which documents locations and times of pesticide spraying) to estimate the subjects‚Äô mothers‚Äô proximity to organophosphate (OP) applications during pregnancy. The subject adolescents ‚ÄĒ estimated to have relatively high levels of prenatal exposure to organophosphates ‚ÄĒ […]

EPA Sued for Registering Known Bee-Killing Pesticide for Use on Bee-Attractive Crops

(Beyond Pesticides, August 27, 2019) The U.S. Environmental Protection Agency (EPA) is the subject to a new legal challenge from environmental groups after approving the use an insecticide shown to be highly toxic to bees and other pollinators.¬† The lawsuit, filed in the 9th Circuit Court of Appeals by the Center for Biological Diversity and Center for Food Safety, aims to stop the use of sulfoxaflor on more than 200 million acres of crops. As EPA under the Trump administration has become increasingly emboldened to fight for industry priorities, concerned organizations and people are responding by supporting legal challenges and working to pass policies that truly protect wildlife and the environment. According to EPA‚Äôs ecological risk assessment for sulfoxaflor, the chemical is ‚Äúvery highly toxic‚ÄĚ to bees. A study published last year in the journal Nature found significant concerns with the chemical‚Äôs ability to harm already declining pollinator populations. ‚ÄúThere is an urgent need to pre-emptively evaluate the potential sub-lethal effects of sulfoximine-based pesticides on pollinators, because such effects are rarely detected by standard ecotoxicological assessments, but can have major impacts at larger ecological scales,‚ÄĚ the authors wrote. EPA had already run in to legal problems associated with its registration […]

European Regulators Issue Warning on Danger of Chlorpyrifos Prior to Release of Full Review

(Beyond Pesticides, August 22, 2019) In early August, experts from European Union (EU) member states and staff members of the European Food Safety Authority (EFSA) announced their conclusion that chlorpyrifos fails to meet criteria for renewed approval for use, potentially moving the EU a step closer to an outright ban. This ends the green light that chlorpyrifos (and its structurally close cousin, chlorpyrifos-methyl) have enjoyed at the EU level since 2006. That permitting is set to expire in January of 2020, although eight member states ‚ÄĒ Germany, Ireland, Finland, Denmark, Sweden, Latvia, Lithuania, and Slovenia ‚ÄĒ had already either banned or never authorized chlorpyrifos use in their countries. In the U.S., states are picking up the slack on efforts against chlorpyrifos use as, in the tenure of the current administration, the Environmental Protection Agency (EPA) has chosen to protect industry rather than human health and the environment. The step EFSA took was unusual in that the agency does not typically publish findings before ongoing peer reviews are completed. EUObserver.com reports that EFSA‚Äôs public statement was triggered by a July 2019 EU request for information ‚Äúon the available outcomes of the human health assessment in the context of the pesticides peer […]

Children’s IQ Negatively Impacted by Maternal Fluoride Exposure, According to Study

(Beyond Pesticides, August 21, 2019) A birth cohort study in Canada found elevated levels of fluoride exposure during pregnancy are associated with lower IQ scores in 3 to 4-year-old children. This new research, published in the journal JAMA Pediatrics, builds on previous analyses that suggest high fluoride exposure is related to adverse effects to children‚Äôs neurodevelopment. Researchers recommend that pregnant mothers should reduce fluoride intake during pregnancy. Noting the controversy of the study, JAMA Pediatrics¬†editor Dr. Dimitri Christakis said it was subjected to ‚Äúadditional scrutiny for its methods and the presentation of its findings.‚ÄĚ The Maternal-Infant Research on Environmental Chemicals (MIREC) program recruited pregnant mothers to participate in the study from 2008-2011. A total of 601 mother-child pairs from 6 major cities participated; 41% of them lived in cities with fluoridated municipal water. Exposure was measured through urine samples as well as self-reported maternal daily intake. Children were between ages 3 and 4 when tested for IQ. A 1mg/L increase in maternal urinary fluoride is associated with a 3.7-point decrease in IQ. These findings echo a previous study in Mexico that found a 6-point lower IQ score in school-age children associated with a 1mg/L in maternal urinary fluoride. Women who […]

Chemical-Intensive Agriculture Is Increasingly Toxic to Insects

(Beyond Pesticides, August 15, 2019) An article in the journal Plos One, ‚ÄúAn assessment of acute insecticide toxicity loading (AITL) of chemical pesticides used on agricultural land in the United States,‚ÄĚ shows that recent shifts in insecticide use‚ÄĒfrom organophosphates and carbamates to synthetic pyrethroids and neonicotinoids‚ÄĒhave made a large contribution to the ongoing insect apocalypse. This shift to insecticides that target insects based on both selective toxicity and delivery method occurs within a context of shrinking habitat and biodiversity. The study, by Michael DiBartolomeis, PhD, Susan Kegley, PhD, Pierre Mineau, PhD, Rosemarie Radford, and Kendra Klein, PhD, presents a measure of acute insecticide toxicity loading that incorporates acute toxicity, quantity used, and the rate at which the insecticide degrades. Goulson et al. applied a similar measure in Great Britain that did not incorporate the rate of degradation. Both studies use the median lethal dose (LD50) to honey bees as a measure of acute toxicity and calculate the potential number of bee deaths based on the number of lethal doses of various insecticides applied in the field. In both cases, researchers used toxicity estimates for honey bees because they are widely available. Other insects may be more or less sensitive. The […]

EPA Refuses to Approve Labeling that Discloses Roundup (Glyphosate) as a Carcinogen

(Beyond Pesticides, August 13, 2019) The U.S. Environmental Protection Agency (EPA) is refusing to approve product labels that disclose that the herbicide glyphosate may cause cancer, according to a press release published last week. The move comes after the state of California listed glyphosate on its Prop 65 list of chemicals known to cause cancer, birth defects or other reproductive harm. Health advocates are condemning the decision as the latest in a long string of EPA actions aimed at benefiting industry at the expense of consumer and public health. Many are concerned that the incessant stream of industry-friendly decisions is eroding public trust in the agency and its ability to act as an independent regulator. While a state judge gave the Prop 65 warning labels the go-ahead, a prior ruling from U.S. District Court Judge William Shubb in Sacramento placed a preliminary injunction on the California requirement that remains in place today. The state added glyphosate to its Prop 65 list after the International Agency for Research on Cancer (IARC) designated the chemical as a group 2A carcinogen. ¬†Under Prop 65, California regulators are required to provide ‚Äúclear and reasonable‚ÄĚ warning labels when any one of four requirements in the […]

Take Action: To Protect Children, EPA Must Decide Based on Science, Not Industry Lobbying

(Beyond Pesticides, August 12, 2019)¬†Once again, the Environmental Protection Agency (EPA) has rejected the evidence provided by independent scientists and sided with the pesticide industry promoting its products; this time, removing a safety for factor for children on some of the most widely used insecticides, synthetic pyrethroids. When EPA cannot do its job, it is time for Congress to step in. Tell Congress: To Protect Children, EPA Must Consider the Independent Peer-Reviewed Science, Not Bend to Industry Lobbying. In a move that challenges the preponderance of independent peer-reviewed scientific findings on children’s health, EPA recently¬†stripped away protections¬†that limit children’s exposure to class of chemicals associated with¬†childhood cancer,¬†autism¬†other learning disorders, and asthma. The result of the agency’s actions will be a dramatic increase in the use of synthetic pyrethroids, insecticides found in indoor and outdoor bug sprays, bug bombs, and often used on conventionally grown fruits and vegetables.

Brazil Approves 262 New Hazardous Pesticides, Makes Death Sole Criteria for Toxicity

(Beyond Pesticides, August 1, 2019) Last month, the Brazilian Ministry of Agriculture approved the registration of 51 additional hazardous pesticides and brought the total to 262 newly approved pesticides this year. Moreover, Brazil‚Äôs health surveillance agency, Anvisa, approved new rules that establish risk of death as the singular criteria for determining toxicity of pesticides. Human Rights Watch, a nonprofit that conducts local investigations, reports that the government has simultaneously been unresponsive to incidents of pesticide poisoning. Brazil‚Äôs president, Jair Boslonoro, is known for his far-right politics, and has been accused of corruption, scandals, and disregard for the environment. This rapid registration of novel pesticides is unprecedented in Brazil. Many of the products are generic versions of existing formulas, with government officials seeking to lower the price of pesticides.
