(Beyond Pesticides, October 24, 2013) A team of scientists in Italy believe they have found the molecular mechanism through which neonicotinoid pesticides adversely impacts the immune system of honey bees. The team’s experiments suggest that exposure to neonicotinoids results in increased levels of a particular protein in bees that inhibits a key molecule involved in the immune response, making the insects more susceptible to attack by harmful viruses. Though previous studies have indicated that exposure to minute amount of neurotoxic pesticides like neonicotinoids severely impair the immune systems of bees, making them more susceptible to pathogens, the underlying mechanism has was not yet been fully  understood. The study, Neonicotinoid clothianidin adversely affects insect immunity and promotes replication of a viral pathogen in honey bees, is published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS). This work is the latest of several studies to add weight to the urgency of repeated calls from U.S. beekeeper and environmental groups for the Environmental Protection Agency (EPA) to  suspend the use of neonicotinoid pesticides, as the European Commission recently decided this past April. Neonicotinoids, a class of insecticides that includes clothianidin and imidicloprid, are taken up […]

(Beyond Pesticides, October 22, 2013) Nearly a week after plant geneticists from the world’s largest agrichemical companies accepted the World Food Prize, an Associated Press (AP) investigation links the effect of their work to soaring pesticide use and resulting health problems.  According to the  AP, the advent of “no-till” farming methods in Argentina with the use of genetically engineered (GE) crops and companion pesticides has caused significant health impacts in farming towns abutting GE fields. Since the introduction of these practices in Argentina by agrichemical companies such as Monsanto, cancer rates have skyrocketed and the number of birth defects has quadrupled. Argentina was an early adopter of GE technology in 1996, when it was billed as the silver bullet to solve world hunger with increased crop  productivity, and improved human and environmental health resulting from decreased pesticide use. The most widely used GE crops, such as Monsanto’s Roundup Ready line of corn and soybeans, allow farmers to apply the herbicide glyphosate during and after seed plantings in order to kill weeds without risk of the main crop dying off. Today, almost all the corn, soy, and cotton produced in the country are GE. As the  AP reports, and researchers in […]

(Beyond Pesticides, October 3, 2013) According to new research, residents are more highly exposed to organophosphate and pyrethroid pesticides in New York City (NYC) than in the U.S. overall.  Researchers from the city’s Department of Health and Mental Hygiene reviewed the 2004 NYC Health and Nutrition Examination Survey (NYC HANES) to compare its pesticide exposure patterns in an urban environment with the nation as a whole. The NYC HANES includes a biomonitoring component to evaluate pesticide exposures by measuring concentrations of organophosphate and pyrethroid metabolites in urine. According to the authors, the findings underscore the importance of considering pest and pesticide burdens on cities, where a dense population results in a single exposure source affecting many people at the same time when regulating pesticide use. Organophosphate metabolites were measured in the urine of 882 New Yorkers, while 1,452 residents were tested for pyrethroid metabolites. As the researchers explain, the building density and disrepair in parts of NYC likely increased the chances of a pest infestation, which in turn can lead to the reliance on indoor pesticide use. By the 1980’s, organophosphates were the most common class of insecticides in the U.S., and were used indoors until the early 2000’s when […]

(Beyond Pesticides, September 30, 2013) A new report, published by UCLA’s Sustainable Technology and Policy Program, finds that the California Department of Pesticides Registration (DPR) has failed to ensure that pesticides it approves are safe. Using methyl iodide as a case study, researchers point to key deficits in the approval process and make recommendations for improvements. Methyl iodide was used as a fumigant to control pests on strawberries, despite its threats to human health. It (i) causes miscarriages, thyroid dysfunction, and cancer, (ii) is neurotoxic, causing psychiatric symptoms and movement disorders similar to Parkinson’s disease,  and (iii)  is a developmental toxin that impairs fetal development. The fumigant was designed as a substitute for methyl bromide, which is slated for phase-out by 2015 as an ozone-depleting chemical under the Montreal Protocol. In the formulation, methyl iodide was combined with another fumigant, chloropicrin, to control for pests and approved for use by California DPR on December 2010, despite severe human health risks presented by scientists and substantial outcry by environmental and farmworker organizations. The report, entitled “Risk and Decision: Evaluating Pesticide Approval in California,” examines the effectiveness of DPR in registering pesticides. Most importantly, the report highlights the flawed risk assessment approach […]

(Beyond Pesticides, September 11, 2013) In a report released Monday, the Government Accountability Office (GAO) finds that the U.S. Environmental Protection Agency (EPA)’s use and oversight of conditional registrations is lacking and unreliable. Conditional registration allows pesticides onto the consumer market without all the required data to assess the chemical’s safety. This has created many serious human and environmental health problems, including bee decline, tree death and potential increases in human health risks. GAO recommends that EPA better track conditional registrations, however, Beyond Pesticides and other concerned groups urge the agency to cancel registrations until all relevant data is submitted and reviewed. According to the findings of the GAO’s report, EPA’s system for tracking pesticides with conditional registration is unreliable and thus, the total number of conditional registrations granted is unclear.   This lack of a reliable system for managing conditional registrations constitutes an ”˜internal control weakness’ because the agency lacks an effective mechanism for program oversight and decision making, according to federal internal control standards cited by GAO. The report states, “The extent to which EPA ensures that companies submit additional required data and EPA reviews these data is unknown. Specifically, EPA does not have a reliable system, such […]

(Beyond Pesticides, August 30, 2013) Months after Central American health ministries issued a  joint declaration citing kidney disease as a top public health priority, the World Bank just approved a new loan to expand sugar cane plantations in Nicaragua. The Bank’s loan represents renewed support for an industry whose workers have been devastated by the disease, which has increasingly been linked to pesticide exposure and exacerbated by heat stress. Kidney disease afflicts agricultural workers in sugar cane fields, killing thousands each year in Central America as well as in Sri Lanka and India. Scientists have yet to definitively uncover the cause of chronic kidney disease (CKD), although emerging research points to toxic heavy metals contained in pesticides as one of the primary culprits. CKD is a condition characterized by a gradual loss of kidney function and is often lethal for poor agricultural workers. As the kidneys begin to fail, wastes can build in the blood causing complications such as high blood pressure, anemia, weak bones, poor nutritional health and nerve damage. Several published studies demonstrate that exposure to certain  organochlorine pesticide products and their heavy metal contaminants used on sugar cane plantations are causally linked to CKD. The recent joint […]

(Beyond Pesticides, August 28, 2013) Industry giant, Syngenta, has filed a legal challenge to the European Union’s suspension of one of its insecticides, thiamethoxam, linked to the decline in bee populations that has been observed in Europe and the rest of the world. Thiamethoxam, a neonicotinoid and active ingredient in Syngenta’s Cruiser seed treatments, is widely used to treat seed and degrades into another neonicotinoid, clothianidin, also subject to a moratorium in the  European Union. Both chemicals are cited in a lawsuit seeking their suspension, which was brought by beekeepers and environmental groups in the U.S. Earlier this year, the European Commission made a landmark decision announcing a two-year continent-wide ban on the neonicotinoid pesticides: clothianidin, imidacloprid and thiamethoxam. The decision came in response to a scientific report by the European Food Safety Authority (EFSA) that identified “high acute risk” to honey bees from uses of the neonicotinoid chemicals. Thiamethoxam, as well as clothianidin, are routinely used to treat seeds, especially for major crops like corn. A  15 member states majority  supported the ban, with eight against, and four abstaining. However, in its press release, Syngenta claims that the European Commission made its  decision on the basis of a flawed […]

(Beyond Pesticides, August 19, 2013) The U.S. Environmental Protection Agency’s (EPA) new pesticide label for honey bee protection, announced Thursday, has been widely criticized by beekeepers and environmentalists as offering inadequate protection in the face of devastating bee decline. Under the new guidelines, the label will prohibit the use of some neonicotinoid pesticides when bees are present, and includes a “bee advisory box” and icon with information on routes of exposure and spray drift precautions. Critics question the efficacy of the label change in curtailing a systemic pesticide that contaminates nectar and pollen, poisoning bees indiscriminately, and the enforceability of the label language, which is geared to managed not wild bees. EPA has not formally acknowledged the peer-reviewed science linking neonicotinoid pesticides to colony collapse disorder and bee decline, as is the case with the European Union’s European Food Safety Authority (EFSA), where neonicotinoids are being phased out. Specifically, the new label applies to pesticide products containing the neonicotinoids imidacloprid, dinotefuran, clothianidin and thiamethoxam. Neonicotinoids are a relatively new class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. They include imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid […]

(Beyond Pesticides, August 5, 2013) Nine state Attorneys General sent a letter to the Senate Environment and Public Works Committee last week expressing their “deep concerns about unduly broad preemption language proposed in S.1009, the Chemical Safety Improvement Act [CSIA].” CSIA would amend the decades old (1976) U.S. chemical law, the Toxic Substances Control Act (TSCA), which in its current form requires absolutely no testing on chemicals (it does not cover pesticides) before they make their way onto the market. Manufacturers are only required to provide the U.S. Environmental Protection Agency (EPA) with  90 days premarket notification before a new chemical is introduced for public consumption. Even after entering the market, the testing and regulation thresholds for these chemicals are grossly inadequate. In the 37 years that TSCA has been in effect, only 200 of the 85,000 industrial chemicals that have ever been in use have been tested or regulated. Many states have not waited for Congress to update these scant protections, opting instead for state reforms to address the potential risks of toxic substances. CSIA endangers the ability for states to enforce these laws, the Attorneys General letter says, explaining that, “Reforms that come at the cost of sweeping […]

(Beyond Pesticides, August 1, 2013) The House of Representatives Appropriations Interior and Environmental subcommittee voted Tuesday 7-4 to approve an appropriations bill that would cut the budget of the U.S. Environmental Protection Agency (EPA) by nearly a third, and includes language that would prevent the agency from enforcing its decision to phase out the use of the neurotoxic fumigant sulfuryl fluoride in our food. The full Appropriations Committee began markups on Wednesday, and, if it passes it will move to a House vote. This is an outrageous attempt to circumvent a basic risk assessment calculation that EPA acknowledges puts the public at risk, given current exposure patterns, to a chemical that is especially hazardous to children. In response to this egregious attempt to stop EPA from doing its job, Beyond Pesticides, along with Environmental Working Group and Fluoride Action Network submitted a letter to the House Appropriation Committee Chairman and Ranking members: Dear Chairman Rogers and Ranking Member Lowey: On behalf of our members and supporters we urge you to strike section 449 from the House Fiscal Year 2014 Interior and Environment Appropriations Act. This section will prohibit the U.S. Environmental Protection Agency from fulfilling its decision to phase-out sulfuryl […]

(Beyond Pesticides, July 31, 2013) Environmental officials are investigating why dozens of dead fish are washing up on the banks of two rivers in western Prince Edward Island (P.E.I.), Canada. For the third time in three years, dead fish have been spotted rising to the surface of Barclay Brook where thousands of fish died in 2011 and 2012 after pesticides from farmers’ fields ran off into the water.   Almost exactly one year ago, when more than 2,000 dead fish were scooped from the near two-mile stretch of Barclay Brook, dead fish again began washing up on the banks of the same river in western P.E.I. following heavy rains last Friday. About a dozen were found the day of the rains, but officials and volunteers with the local watershed group have since found more than 100. The nearby Mill River also experienced a fish kill, with the first dead fish reported being washed up on Monday. P.E.I. Department of Environment and Environment Canada officials are investigating the fish kills. Government spokesman Wayne MacKinnon says pesticide run-off could be the cause of the latest fish kill, but water samples collected on the weekend have yet to be tested. Dale Cameron, a […]

(Beyond Pesticides, July 26, 2013) Thousands of people from across the country took action last month to prevent Dow AgroSciences from using its influence to insert Farm Bill language that would allow the food uses of the pesticide sulfuryl fluoride to continue, despite a U.S. Environmental Protection Agency (EPA) proposal to phase it out. Dow’s latest attempt to keep this neurotoxic fumigant in our food is to defund EPA’s ability to regulate its use. Language inserted into the 2014 Interior and Environment House Appropriations Bill will prevent EPA from enforcing its previous decision to phase out the use of sulfuryl fluoride. Tell Your Representative Today: Remove Section 449 from the House Appropriations Bill. According to Section 449 on sulfuryl fluoride, none of the funds made available in the appropriations bill may be used by EPA “that in any way removes, withdraws, revokes, or stays tolerances for the pesticide chemical sulfuryl fluoride if that final order takes into consideration aggregate or cumulative exposure to other substances related to sulfuryl fluoride or its metabolites or degradates.” This will essentially prevent EPA from doing the job Congress assigned to the agency under the Federal Food, Drug, and Cosmetic Act, which requires that EPA […]

(Beyond Pesticides, July 24, 2013) Gina McCarthy, a veteran environmental regulator and President Obama’s pick to run the U.S. Environmental Protection Agency (EPA),  finally had her appointment confirmed by the U.S. Senate after an almost five month delay imposed by Senate Republicans. Ms. McCarthy’s appointment got caught up with other cabinet appointments that Republicans were blocking. News of her confirmation was applauded by environmental groups who urge her to focus of several key environmental issues before the agency including climate change, farmworker justice, and pollinator protection. Last Friday the Senate confirmed Gina McCarthy to lead EPA, ending the agency’s longest period without a permanent administrator and closing the door on a contentious dispute over votes on executive nominees. Ms. McCarthy, who currently heads the agency’s Air and Radiation Office, was confirmed on a 59-40 vote. Ms. McCarthy will succeed Lisa Jackson, who stepped down in February, and replaces acting Administrator Bob Perciasepe. The Senate Environment and Public Works Committee cleared Ms. McCarthy’s nomination in May. Environment and Public Works Chairwoman Barbara Boxer (D-Calif.) said ahead of the vote that the Senate could “not have a more qualified, more bipartisan nominee,” noting that Ms. McCarthy had worked for Republican governors in […]

(Beyond Pesticides, July 23, 2013) When shopping for sportswear nowadays, you might notice the stickers or tags on some clothing items touting the apparel as “antimicrobial.” What’s not mentioned on those tags, however, is the point that these antimicrobials, often titanium dioxide or silver nanoparticles (nanosilver), are largely untested, and recent studies are revealing that these substances could seep into a person’s sweat and end up being absorbed through one’s skin. Lead researcher of the study published in Environmental Science and Technology, Natalie von Gotz, Ph.D,, found that some pieces of clothing released significant amounts of nanosilver. Manufacturers are adding nanoparticles to clothing in order to tout their ability to block UV rays (titanium dioxide) or prevent mold and smells (nanosilver) on clothing. However, the long-term impacts of this new technology to human health and the environment are still unknown. There are concerns about the ability of nanomaterial to travel through the human body and damage brain, liver, stomach, testes and other organs, as well as pass from mother to fetus, according to a recent Natural Resources Defense Council (NRDC) report. Laundering these products ultimately washes them into our environment because sewage treatment plants are not set up to filter […]

(Beyond Pesticides, July 18, 2013) A few months after the groundbreaking decision to suspend the use of three neonicotinoids shown to be highly toxic to bees, the European Commission is moving forward again with a proposal to restrict the use of the insecticide fipronil, which has also   been identified as posing an acute risk to honey bees. The proposal is backed by a Member State experts meeting in the Standing Committee on Food Chain and Animal Health. This proposal follows a European Food Safety Authority (EFSA)  scientific risk assessment, published on May 27, 2013, which found that seeds treated with pesticides containing fipronil pose an acute risk to Europe’s honey bee population. According to this assessment, it was found that fipronil poses a high acute risk to honeybees when used as a seed treatment for corn. Specifically, EFSA concluded that high acute risk from dust drift resulting from treated corn exists, and identified several data gaps and study limitations for other field crops. Data on nectar and pollen could not be evaluated. 23 Member States supported the fipronil restriction, 2 Member States voted against and 3 Member States abstained during the standing committee vote. This latest EU-wide restriction comes […]

(Beyond Pesticides, July 12, 2013) New research concludes that exposure to a combination of both arsenic and estrogen, at levels U.S. Environmental Protection Agency (EPA) considers “safe” for humans, can cause cancer at elevated levels in prostate cells. Texas Tech University researchers revealed that humans exposed to a combination of both toxicants were almost twice as likely to develop cancerous cells in their prostate. The study is published in the peer-reviewed journal The Prostate. While it is established that both arsenic and estrogen can cause cancer, the research raises concerns about the dangers of chemicals in combination, and the efficacy of regulations that are established by testing one chemical at a time. Kamaleshwar Singh, PhD., is an assistant professor at the Institute of Environmental and Human Health at Texas Tech. “The majority of cancers are caused by environmental influences,” Dr. Singh remarked to Texas Tech Today, “Only about 5 to 10 percent of cancers are due to genetic predisposition. Science has looked at these chemicals, such as arsenic, and tested them in a lab to find the amounts that may cause cancer. But that’s just a single chemical in a single test. In the real world, we are getting exposed […]

(Beyond Pesticides, July 10, 2013) Several beekeeping organizations have filed suit against the U.S. Environmental Protection Agency’s (EPA) to reverse a recent decision to register a new  pesticide, sulfoxaflor, which is highly toxic to bees. The beekeepers are not satisfied that their submitted concerns were properly addressed by EPA before registration was granted. Sulfoxaflor is a sub-class of the neonicotinoid pesticides that have been linked to global bee declines. The suit is filed as the beekeeping industry across the country struggles for survival, and faces the costly effects of pesticides upon their businesses. The National Pollinator Defense Fund, American Honey Producers Association, National Honey Bee Advisory Board, the American Beekeeping Federation, and beekeepers Bret Adee, Jeff Anderson and Thomas R. Smith submitted the case in the U.S. Ninth Circuit Court of Appeals, requesting changes in the sulfoxaflor product label, the Biological Economic Assessment Division (BEAD) assessment of the value of pollinators and their established habits, and the EPA’s Risk Assessment Process. The requested changes would acknowledge pollinator’s critical role in the U.S. food supply, and ensure that decisions regarding new pesticides comply with applicable laws. Another legal challenge submitted in March 2013 by beekeepers, environmental and consumer groups, including Beyond […]

(Beyond Pesticides, July 3, 2013) In light of recent action in Europe to suspend to use of certain neonicotinoid pesticides, Beyond Pesticides joined 12 other environmental and advocacy organizations in urging the Obama administration to direct the U.S. Environmental Protection Agency (EPA) to follow the European Union’s (EU) lead in recognizing that risks posed by these pesticides are unacceptably high, and suspend the use of these chemicals in the U.S. to protect pollinators and the nation’s agricultural economy. The letter urges the Obama administration to not only direct EPA to follow Europe’s lead in suspending certain neonicotinoid pesticides uses, but requests even more protective measures, including a minimum two-year suspension for all outdoor uses of neonicotinoid insecticides pending resolution of their hazards to bees and beneficial organisms. Highlighting the negative environmental and economic impacts of outdoor uses of the EPA-approved neonicotinoid insecticides: imidacloprid, clothianidin  , thiamethoxam, dinetofuran and acetamiprid, as well as a recognition that the initial risk assessments for these chemicals fail to adequately consider key risks to bee health, the letter to President Obama notes that it, “would not be responsible to continue to allow these threatening compounds to be used so broadly.” On average, U.S. beekeepers lost […]

(Beyond Pesticides, June 28, 2013) The U.S. Environmental Protection Agency (EPA) released a draft “State of the Science” report last week acknowledging that low dose responses “do occur in biological systems” while defending its current risk assessment procedures as adequate for evaluating low dose effects. This report comes after EPA’s long running failure to fully implement a 1996 Congressionally mandated program to evaluate endocrine disruptors, and heavy criticism last year from prominent scientists who said EPA’s testing procedures are outdated. In 1999 the Natural Resources Defense Council (NRDC) filed a lawsuit against the EPA for failing to meet a statutory deadline for implementation of the Endocrine Disruptor Screening Program (EDSP) required under the 1996 Food Quality Protection Act, forcing the EPA to make a settlement agreement. As a result of  NRDC et al. v. EPA (No. C-99-03701 CAL) filed in the Northern District of California, EPA agreed to start requiring screening and testing of certain chemicals varying by date, using a tiered system. EPA’s two-tiered screening and testing system, requires that EPA will identify which chemicals are able to interact with the endocrine system in Tier 1. Tier 2 screening process was designed to go one step further, requiring EPA […]

(Beyond Pesticides, June 26, 2013) Pesticide use has sharply reduced the regional biodiversity of stream invertebrates, such as mayflies and dragonflies, finds a study published in the Proceedings of the National Academy of Science. While previous research has shown similar decreases in individual streams, this new study analyzes the effects of pesticides over broad regions. This is one of several recent findings that show pesticides pose a long-term threat to important ecosystems. The study, entitled Pesticides reduce regional biodiversity of stream invertebrates, notes that losses of biodiversity caused by anthropogenic activities during the past 50 years are unprecedented in human history. A team of researchers sampled 23 streams in the central plains of Germany, 16 in the western plains of France, and 24 in southern Victoria, Australia. Researchers classified streams according to three different levels of pesticide contamination: uncontaminated, slightly contaminated, and highly contaminated. Utilizing a model-based approach to account for other environmental variables, the team observed that losses in taxonomic diversity were, to a large degree, determined by the loss of species specifically vulnerable to pesticides. Overall, they found that there were up to 42% fewer species in highly contaminated than in uncontaminated streams in Europe. Highly contaminated streams […]

(June 10, 2013, Beyond Pesticides) The Washington State Department of Agriculture (WSDA) on June 6 rejected a petition by Thurston County Commissioners to restrict sale, use and application of neonicotinoid insecticides. On April 8, 2013, the Commissioners requested the action by WSDA because of concerns about the effect of neonicotinoid insecticides on honey bee colony health. The Commissioners were acting on “substantial bee colony loss in 2012” reported by the Olympia Beekeepers Association. In its request, the Commissioners asked the state to implement a “restriction on the purchase, sale, distribution and application of the neonicotinoid class of insecticides for ornamental use to persons or entities with a valid WSDA pesticide applicator license” and indicated that “immediate action on a local level is appropriate and necessary.” Beyond Pesticides wrote a letter of support in favor of the petition. Neonicotinoids are a relatively new class of insecticides that share a common mode of action that affect the central nervous system of insects, resulting in paralysis and death. They include imidacloprid, acetamiprid, clothianidin, dinotefuran, nithiazine, thiacloprid and thiamethoxam. According to the EPA, uncertainties have been identified since their initial registration regarding the potential environmental fate and effects of neonicotinoid pesticides, particularly as they […]

(Beyond Pesticides, June 3, 2013) A new study, published in Proceedings of the Royal Society, found that genetically engineered (GE) AquaBounty AquaAdvantage salmon can successfully cross-breed with brown trout, a closely related species. GE salmon, created by the biotech company AquaBounty, are designed to reach maturity faster than their wild counterparts and would be the first GE animal approved for human consumption in the United States. As a result of this study, the authors “…suggest that interspecific hybridization be explicitly considered when assessing the environmental consequences should transgenic animals escape to nature.” The study not only found that GE salmon can cross-breed with brown trout, but also that their GE hybrid offspring could outgrow wild salmon, non-GE hybrid offspring, and even GE salmon. The GE hybrids also out-competed wild salmon and GE salmon in simulated stream environments, further stunting the growth of other fish. According to Andrew Kimbrell, executive director of Center for Food Safety, “This study highlights yet another ecological risk of these hazardous genetically engineered fish. The FDA’s [U.S. Food and Drug Administration] attempt to approve these gene altered fish without even analyzing these irreversible impacts on our native salmon and trout populations is unlawful and a gross […]
