(Beyond Pesticides, January 31, 2012) The Environmental Protection Agency (EPA) has proposed an expansion in pyrethrins/pyrethroid insecticide uses as part of its cumulative risk assessment for this neurotoxic class of chemicals. In the cumulative risk assessment, EPA concludes that pyrethroids “do not pose risk concerns for children or adults,” ignoring a wealth of independent data that links this class of chemicals to certain cancers, respiratory and reproductive problems, and the onset of insect resistance. It went as far as to state that its cumulative assessment supports consideration of registering additional new uses of these pesticides, potentially opening the flood gates for manufacturers to bombard the market with more pyrethroid pesticides, endangering the health of the public. The agency is accepting public comments through February 8, 2012. Tell EPA that it has ignored numerous health effects and that these pesticides do pose unacceptable risks to human health given the availability of alternatives. Submit comments directly to the EPA docket or sign-on to Beyond Pesticides’ comments. In its comments to EPA, Beyond Pesticides states: There are several major concerns and flaws plaguing this cumulative assessment, which therefore does not meet the regulatory burden in fully evaluating synthetic pyrethroids’ effect on public and […]

(Beyond Pesticides, December 15, 2011) New research suggests that the recent re-emergence of bed bug infestations may originate from insecticide use in the tropics. According to the results, which were presented at the American Society of Tropical Medicine and Hygiene’s 60th annual meeting, exposure to treated bed nets and linens caused populations of bed-bugs to build resistance to those chemicals. The findings presented at the gathering showed that 90% of 66 populations sampled from 21 U.S. states were resistant to a group of insecticides, known as pyrethroids, commonly used to kill unwanted bugs and flies. Other research has already shown that an over-reliance on chemical controls over the years has helped bed bugs evolve to be resistant to these chemicals. One of the co-authors, evolutionary biologist Warren Booth, Ph.D. from North Caroline State University in Raleigh, told the BBC news that the genetic evidence he and his colleagues had collected show that the bed-bugs infecting households in the U.S. and Canada in the last decade are not domestic bed bugs, but imports. The team collected samples from across the eastern U.S. and discovered populations of bed-bugs that are genetically very diverse. “If bed-bugs emerged from local refugia, such as poultry […]

(Beyond Pesticides, October 20, 2011) The Center for Biological Diversity filed a lawsuit yesterday against the Environmental Protection Agency (EPA) and U.S. Fish and Wildlife Service (FWS) for failing to evaluate and act on threats to the threatened California red-legged frog posed by more than 60 toxic pesticides used in and near its habitats. The Center had announced its intent to sue the two agencies back in December 2010. A 2006 legal settlement secured by the Center requires EPA to assess the impacts of harmful pesticides on red-legged frogs and formally consult with the Fish and Wildlife Service to address those impacts. EPA determined that widespread use of more than 60 pesticides is likely harming red-legged frogs, but since the agency and the Fish and Wildlife Service have failed to complete the required evaluations, no permanent protections for frogs have been put in place. “Federal agencies acknowledge that scores of pesticides may harm California’s rare red-legged frogs, but for years now they’ve neglected to complete biological evaluations of the effects of these chemicals,” said Jeff Miller, a conservation advocate with the Center. “California’s imperiled frogs are suffering as a result.” “Biological opinions,” the evaluations required by the Endangered Species Act, […]

(Beyond Pesticides, September 26, 2011) On September 23, 2011, the Centers for Disease Control and Prevention (CDC) published a study in its Morbidity and Mortality Weekly Report linking pesticides sprayed in attempts to control bed bugs to poisoning incidents and death. Because bed bugs do not transmit disease and can be controlled without pesticides, this risk is completely unnecessary. The study, “Acute Illnesses Associated with Insecticides Used to Control Bed Bugs,” utilized data from California, Florida, Michigan, North Carolina, New York, Texas, and Washington. In those seven states, over 100 poisonings, including one fatality, were associated with bed bug-related insecticide use. The CDC researchers used data from states participating in the Sentinel Event Notification System for Occupational Risks (SENSOR)-Pesticides program and the New York City Department of Health and Mental Hygiene (NYC DOHMH). The authors defined “acute illness” associated with an insecticide used to control bed bugs as two or more acute adverse health effects resulting from exposure to an insecticide used for bed bug control. The study reports: A total of 111 illnesses associated with bed bug–related insecticide use were identified; although 90 (81%) were low severity, one fatality occurred. Pyrethroids, pyrethrins, or both were implicated in 99 (89%) […]

(Beyond Pesticides, August 11, 2011) A combination of eleven different kinds of commonly used pyrethroids were tested on mice in a new study which found that, at real-world exposure levels, the insecticides can produce heightened toxicity that is equal to the sum of each insecticide’s individual effect. The mixture of similar-acting insecticides works by over-stimulating electronic channels in the mouse’s brain cells and eventually causing death. This study adds to the growing body of research on the toxicity of pesticide combinations in nature and showcases the need for policy change because the current risk assessment approach to regulating pesticides fails to look at chemical mixtures and synergistic effects. The U.S. Environmental Protection Agency (EPA) currently regulates on a chemical-by-chemical basis, but as this study demonstrates, interacting chemicals can have synergistic effects at very low levels, where a “chemical cocktail” of multiple interacting chemicals combine to have greater effects than expected. Pesticides can also have a cumulative “toxic loading” effect both in the immediate and long term. Researchers exposed mice brain cells to eleven different food-use pyrethroid insecticides either singly or in a mixture in the study entitled ”Additivity of pyrethroid actions on sodium influx in cerebrocortical neurons in primary culture.” […]

(Beyond Pesticides, July 22, 2011) Parallel bills have been introduced in the U.S. Senate and U.S. House of Representatives designed to increase federal research on endocrine disrupting chemicals and ensure public safety by restricting or eliminating chemicals found to present unacceptable risks to public health. S 1361, introduced by Senator John Kerry (D-MA), and HR 2521, introduced by Rep. Jim Moran (D-VA), are both titled the Endocrine-Disrupting Chemicals Exposure Elimination Act. The bills would establish a scientific panel at the National Institute of Environmental Health Sciences (NIEHS) to evaluate up to ten chemicals per year that potentially affect the endocrine system and would create a trigger to ban those found most harmful to public health. The bills would create a more updated scientific evaluation process than any that currently exists in the federal government for reviewing potential endocrine disruptors and would have a strong regulatory mandate to ban or restrict chemicals that are found to present serious health risks. The specific process outlined directs the National Toxicology Program at NIEHS to evaluate each chemical according to (i) the amount of evidence that it is an endocrine disruptor, (ii) the “level of concern” that it may disrupt hormones, and (iii) the […]

(Beyond Pesticides, May 9, 2011) The Endocrine Disruptor Exchange Inc. (TEDX), founded by Theo Colborn, PhD, has released a list of chemicals with the potential to affect the endocrine system. According to TEDX, every chemical on the TEDX List has one or more verified citations to published, accessible, primary scientific research demonstrating effects on the endocrine system. Endocrine disruptors are chemicals that impact traditional endocrine glands, their hormones and receptors such as estrogens, anti-androgens, and thyroid hormones. To date there are approximately 800 endocrine disruptors on the TEDX List. Download the TEDX List (Excel) Many everyday chemicals that people are exposed to can wreak havoc on the body’s endocrine system. Pesticides such as triclosan, atrazine, permethrin and many others have been associated with effects on the body’s hormone system. Visit the Pesticide Induced Disease Database for more on the chemicals linked to endocrine disruption. Endocrine effects include direct effects on traditional endocrine glands, their hormones and receptors such as estrogens, anti-androgens, and thyroid hormones, as well as signaling cascades that affect many of the body’s systems, including reproductive function and fetal development, the nervous system and behavior, the immune and metabolic systems, the liver, bones and many other organs, glands […]

(Beyond Pesticides, May 5, 2011) Over 70 international organizations, including health and environmental groups, landscapers and farmers are proclaiming tomorrow, Friday, May 6, 2011, Lawn Pesticide Awareness Day in honor of Dr. June Irwin’s leading role in passage of North America’s first lawn pesticide ban in Hudson, Quebec, on May 6, 1991. “The town of Hudson, Quebec, and particularly the actions of June Irwin, M.D., have sent a clear signal to communities all across North America that the use of lawn and landscape pesticides is both harmful and unnecessary,” said Jay Feldman, the founder of Beyond Pesticides of Washington, D.C. “Chemical lawn pesticides are scientifically linked to cancer in people and pets, and are known to be toxic to the nervous and immune system, endocrine disruptors, and tied to respiratory effects such as asthma. Alternative practices that rely on maintenance techniques and soil health that prevent unwanted insect and weeds are far more effective than their chemical counterparts.” Now, for 80 percent of Canadians and a growing number of Americans, synthetic chemical lawn pesticides are becoming a habit of the past. In 1991, exactly six years from the first day she voiced her concerns at a town meeting, May 6, […]

(Beyond Pesticides, March 28 2011) Researchers found that exposure to organochlorine pesticides significantly alters semen quality in young men from southeast Spain. The study found 18 pesticides in the blood of the study participants, including some banned in Spain, such as DDT, and others legal in in the country, such as the fungicide vinclozolin. The analysis was conducted by Clemente Aguilar from the Medical Research Laboratory of the University Hospital San Cecilio, Granada, Spain, and coordinated by Marieta Fernández, Marina Lacasaña and Nicolás Olea (University of Granada), basing on a sample of 280 volunteer students aged 18-23 years from the University of Almería, Spain. All the study participants had at least one pesticide in considerable concentrations. The average number of pesticides detected in the blood tests was 11. Southeast Spain is a region where two out of ten young men have poor sperm density. Even though exposure to some organochlorines proved to increase total spermatic number and total sperm motility levels, other pesticides were highly associated with a reduction in sperm levels. This might be due to the fact that some of these pesticides are considered to be estrogenic endocrine disruptors. Endocrine disruptors are substances that interfere with natural hormones […]

(Beyond Pesticides, March 10, 2011) The American Public Health Association (APHA) recently adopted 17 new policies at its 138th Annual Meeting in Denver, addressing a broad range of public health concerns, including a new policy calling for greater government action to protect the public from endocrine-disrupting chemicals (EDCs). The policy statement follows official positions released earlier in 2010 by both the American Medical Association (AMA) and the Endocrine Society in that more needs to be done to protect the public from endocrine-disrupting chemicals, or those that interfere with hormone action. Specifically, APHA urges: ”¢ Support for the Endocrine Society and the American Medical Association in proclaiming that more needs to be done to protect the public from potential health risks of exposure to EDCs. ”¢ That given the magnitude and urgency of the public health threat and the recognition that collectively EDCs likely will have common or overlapping effects on the endocrine system, steps should therefore be taken by federal agencies with regulatory oversight for various individual EDCs to coordinate and find synergies among themselves to coordinate and find synergy among federal agencies with regulatory oversight over various individual EDCs. ”¢ Health professionals and scientists with expertise in various aspects […]

(Beyond Pesticides, February 16, 2011) Many agricultural pesticides —including some previously untested and commonly found in food— disrupt male hormones, according to new tests conducted by British scientists. Meanwhile, U.S. researchers at the National Institutes of Health have found that people who used two specific varieties of pesticide were 2.5 times as likely to develop Parkinson’s disease. Pesticides Impact Male Hormones Evidence suggests that there is widespread decline in male reproductive health and anti-androgenic pollutants, also known as endocrine disruptors, may play a significant role. Thirty out of 37 pesticides tested by the researchers at the University of London altered male hormones, including 16 that had no known hormonal activity until now. There was some previous evidence for the other 14. Most are fungicides applied to fruit and vegetable crops, including strawberries and lettuce. The study, “Widely Used Pesticides with Previously Unknown Endocrine Activity Revealed as in Vitro Anti-Androgens,” is published in Environmental Health Perspectives. The British researchers screened the chemicals using in vitro assays, which use human cells to check whether the pesticides activate or inhibit hormone receptors in cells that turn genes on and off. Scientists, however, are uncertain what actually happens in the human body at the […]

(Beyond Pesticides, January 24, 2011) Citing the U.S. Environmental Protections Agency’s failure to protect over 200 endangered species from pesticides under the Endangered Species Act (ESA), two national environmental groups filed on January 20, 2011 a lawsuit to force agency implementation of the act. In what is penned by the groups, the Center for Biological Diversity and Pesticide Action Network North America (PANNA), as the most comprehensive legal action ever brought under ESA, the lawsuit specifically challenges EPA’s failure to consult with the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service on the impacts of hundreds of EPA-registered pesticides that are known to be harmful to endangered and threatened species. “For decades, the EPA has turned a blind eye to the disastrous effects pesticides can have on some of America’s rarest species,” said Jeff Miller, a conservation advocate with the Center. “This lawsuit is intended to force the EPA to follow the law and ensure that harmful chemicals are not sprayed in endangered species habitats.” According to EPA, the Endangered Species Act requires federal agencies, in consultation with FWS and/or the NOAA Fisheries Service, “to ensure that actions they authorize, fund, or carry out are not likely […]

(Beyond Pesticides, January 21, 2011) Further proof of the ineffectiveness of chemical pest control has emerged in the form of a study from The Ohio State University documenting the growing resistance of bed bugs to pesticide treatments. The study shows that modern bed bugs have developed the ability to defend themselves against pyrethroid pesticides, due in part to the widespread use of such treatment methods. These findings highlight the need for widespread adoption of alternative, non-chemical methods for controlling bed bugs and other insect pests. The study, which was published in the journal PLoS ONE, is entitled “Transcriptomics of the Bed Bug (Cimex lectularius).” The researchers found that the bugs developed the ability to produce certain enzymes, which can break down toxic chemicals, at higher levels of than previous generations. These enzymes allow the chemicals to be easily excreted by the insects without being harmed. When comparing modern bugs to a colony that has existed in isolation for several decades — without any exposure to pesticides — the team found strong evidence of resistance. Bugs from the isolated colony were readily killed when exposed to even small amounts of pyrethroids. However, the modern bugs, which have been exposed to pesticide […]

(Beyond Pesticides, January 5, 2011) Your voice is critical in generating public comments on a petition, published in the Federal Register, to ban the antibacterial chemical triclosan. As you may know, this chemical, now found in the bodies of 75% of the U.S. population, is linked to endocrine disruption, bacterial and antibiotic resistance, dioxin contamination, and contaminated fish and biosolids. We have five more weeks —until February 7, 2011— to let EPA know that triclosan must be banned to protect the public, workers and the environment. Click here for the document you can use to publicize the public comment period on Ban Triclosan petition or email info@beyondpesticides for the word version. EPA published in the Federal Register a petition, filed by 82 public health and environmental groups, to ban the hazardous antimicrobial/antibacterial pesticide triclosan for non-medical use. The chemical is found in products from clothing to soaps. The Federal Register notice (Petition for a Ban on Triclosan, 75 FR 76461, December 8, 2010) announces a public comment period until February 7, 2011 on the need to ban triclosan under numerous federal statutes from pesticides, clean water, safe drinking water, to endangered species. SUGGESTED ACTION AND SAMPLE PUBLIC COMMENT: Please send […]

(Beyond Pesticides, December 8, 2010) A new study finds that oral contraceptives are not the main culprit in estrogenic pollution of U.S. rivers and drinking water. Instead, the contribution of contraceptives is quite small compared to other human, industrial and agricultural sources, including pesticides. Recent observed feminization of aquatic animals has raised concerns about estrogenic compounds in water supplies and the potential for these chemicals to reach drinking water. Public perception frequently attributes this feminization to oral contraceptives (OCs) in wastewater and raises concerns that exposure to OCs in drinking water may contribute to the recent rise in human reproductive problems. Studies have suggested that long-term exposure to low levels of estrogens in water may adversely affect human health. This new information eases concerns that contraceptives are a major factor contributing to feminized fish and frogs. This study, “Are Oral Contraceptives a Significant Contributor to the Estrogenicity of Drinking Water?” reviews the literature regarding various sources of estrogens, in surface, source and drinking water, to determine whether OCs were the source of estrogen in surface waters, with an emphasis on the active molecule that comes from OCs. The authors find that industrial and agricultural sources not only discharge estrogens, but […]

(Beyond Pesticides, November 18, 2010) Yesterday, the U.S. Environmental Protection Agency (EPA) announced that it has identified a list of 134 chemicals that will be screened for their potential to disrupt the endocrine system, along with a draft of the policies and procedures that the agency will follow for testing. Endocrine disruptors are chemicals that that interfere with the hormones produced or secreted by the human or animal endocrine system, which regulates development, metabolism, growth, and reproduction. These man-made chemicals are used in everyday materials but appearing in increasing levels throughout the environment. For years, scientists have noted strange anomalies in fish and wildlife in locations where endocrine disrupting chemicals (EDCs) are found. A recent study found that an astounding 100 percent of small mouth bass in certain sites of the Potomac River basin have exhibited both male and female organs, a characteristic linked to EDCs. According to a 2009 study by the U.S. Geologic Survey, the occurrence of “intersex” fish is now found to be nationwide. EPA is currently proceeding with endocrine disruptor screening on three fronts: 1) Developing and validating Tier 2 tests; 2) Selecting chemicals for screening and testing; and 3) Implementing the policies and procedures the […]

(Beyond Pesticides, October 25,2010) In an effort to control sea lice in farmed Atlantic salmon Health Canada has approved a request by the province of New Brunswick to use the pesticide Alphamax, whose active ingredient is deltamethrin. The high concentrations of salmon in aquaculture facilities has lead to major problems with sea lice, a type of parasitic crustacean that attaches to the fish. Health Canada has approved the use of the restricted pesticide deltamethrin through December of this year. While many salmon farmers are pleased, the decision by Canada’s federal agency has many local fishermen concerned about the effects the pesticide will have on fish and shellfish populations. “Basically we are shocked in a nutshell,” said Grand Manan Fishermen’s Association project manager Melanie Sonnenberg, adding, “Dsappointed doesn’t cover it.” The use of deltamethrin will be restricted to tarped cages or well boats, boats with large holds. Treatment would involve placing fish in the boats, bathing them in Alphamax and releasing them back into cages along with the treated water. The industry is ready to start using the treatment in the Bay of Fundy. Fish farmers have been challenged in controlling sea lice outbreaks this summer, particularly in the upper Passamaquoddy […]

(Beyond Pesticides, September 14, 2010) A new study confirms that indoor uses of consumer products, including pesticides, are the primary sources of indoor exposure to endocrine disruptors —chemicals that disrupt hormones and cause adverse developmental, disease, and reproductive problems— and shows that indoor levels are higher than those outdoors. Researchers from Silent Spring Institute, Columbia University, and the University of California-Berkeley measured airborne concentrations of endocrine disruptors in two California communities: Bolinas, a rural, affluent coastal town, and Richmond, a working-class city ringed by oil refineries. The study is published online in the September 1, 2010 issue of Environmental Science & Technology. The researchers analyzed 104 chemicals in 50 homes, including both chemicals that penetrate indoors from outdoor industrial and transportation sources and those from indoor use of consumer products and building materials. Similar levels of contamination were found inside homes in both communities, but outdoor levels were higher in Richmond. Among the chemicals found were pesticides, phthalates, parabens, PBDE flame retardants, and PCBs. A total of 38 pesticides are evaluated, including banned organochlorines (e.g., DDT, PCP), and current use products such as carbamates (e.g., propoxur), organophosphates (e.g., chlorpyrifos), and pyrethroids (cypermethrin). Thirteen pesticides were detected outdoors and sixteen pesticides […]

(Beyond Pesticides, August 20, 2010) Behind closed doors this past Monday, the U.S. Environmental Protection Agency (EPA) and Bayer CropScience reached an agreement on a set of measures to gradually reduce and ultimately ban fully the use of the insecticde aldicarb in the U.S. This decision arrives on the heels of a revised risk assessment in which EPA found that babies and children under the age of five can ingest levels of the insecticide through food and drinking water at levels that exceed limits that the agency finds safe, and 25 years after 2,000 people fell ill after eating watermelons that were tainted with the pesticide. Though Beyond Pesticides applauds any decision to remove toxic chemicals from the environment, the problem with this cancellation, as with virtually all voluntary cancellations, is that the chemical can be legally used for years —eight years in this case — leaving open the opportunity for continued human and environmental exposure and harm. The decision was reached after EPA completed a revised risk assessment indicating that the pesticide does not meet the agency’s food safety standards. EPA scrutinized recent food consumption data from USDA to complete the risk assessment, which considered the percent of the […]

(Beyond Pesticides, July 30, 2010) Adding to a campaign that Beyond Pesticides launched in 2004 to alert the public and pressure government to restrict the highly toxic antibacterial chemical triclosan -commonly found in antibacterial soaps and household and consumer products, the Natural Resources Defense Council (NRDC) filed a lawsuit earlier this week against the Food and Drug Administration (FDA) for failing to issue a final rule regulating the chemical. The lawsuit follows on the heels of two petitions filed by Beyond Pesticides and Food and Water Watch in 2009 and 2010 with FDA and the U.S. Environmental Protection Agency (EPA), respectively, to ban the chemical. Because of the widespread poisoning and environmental contamination caused by triclosan, the petitions cite numerous violations of statutory duties under the Federal Food, Drug and Cosmetics Act, Federal Insecticide, Fungicide, and Rodenticide Act, Clean Water Act, Safe Drinking Water Act, and Endangered Species Act. The NRDC lawsuit adds yet another dimension to the legal violations involving agency malfeasance on triclosan by asking the court to impose a strict deadline for FDA to finalize a proposed rule that has been pending for 32 years and could ban many uses of triclosan and its chemical cousin triclocarban. […]

(Beyond Pesticides, April 22, 2010) In a new consumer factsheet posted April 8, 2010, the U.S. Food and Drug Administration (FDA) attempts to moderate the position it took in a February 23, 2010 letter to Congress in which it said, “[E]xisting data raise valid concerns about the effects of repetitive daily human exposure to these antiseptic ingredients” and “FDA shares your concerns over the potential effects of triclosan and triclocarban as endocrine disruptors that has emerged since we issued the TFM [Tentative Final Monograph] in 1994.” Instead, in bureaucractic-speak FDA is now saying, “[T]riclosan is not currently known to be hazardous to humans.” Safety advocates say that the FDA’s latest statement creates public confusion as the triclosan market continues to grow and manufacturers in the soap and cosmetics industry daily push misleading advertising claims about the protection from bacteria attributed to the toxic ingredient triclosan. While equivocating on the science on triclosan’s adverse effects, FDA does question the efficacy of the widely marketed triclosan products with the statement, “At this time the agency does not have evidence that triclosan in antibacterial soaps and body washes provides any benefit over washing with regular soap and water.” The new FDA factsheet, featured […]

(Beyond Pesticides, April 19, 2010) Mississippi Governor Haley Barbour last week signed a childhood asthma management and prevention bill into law that includes provisions requiring all public school districts to implement an Integrated Pest Management (IPM) program and prohibiting the use of hazardous substances such as cleaning products and pesticides. Although the bill reads as though it will do a lot for children with asthma, with regard to the actual eliminatiion or significant reduction of toxic pesticide use at schools, the bill is weakly worded and will need strong regulations to be meaningful in protecting children from pesticide-asthma triggers. Specifically, this new law, effective July 1, 2010, requires schools to allow students to self-administer asthma and anaphylaxis medication; recommends students with asthma to have an Asthma Action Plan on file at the school; provides training for teachers, nurses, and all other school staff on asthma; requires buses to minimize idling time; requires local school health councils to adopt and support the implementation of a local school wellness policy that includes minimizing children’s exposure to pollutants that can aggravate asthma and prohibits the use of hazardous substances such as cleaning products and pesticides in and around school buildings during the hours […]
