(Beyond Pesticides, December 21, 2019) A study at the University of Maine (UMaine) finds that adding blackberry leaf litter in stormwater catch basins creates an “ecological trap,” enticing mosquito females to lay eggs in sites unsuitable for larvae survival. Employing this new and incredibly viable “attract-and-kill’ tool for mosquito control shows potential for preventing the breeding of mosquitoes that may carry insect-borne diseases, especially in urban environments. Stormwater catch basins regularly accumulate leaf litter, which serve as habitat for the mosquito species Culex pipiens (Cx. Pipiens) that may carry West Nile virus. Previous University of Maine research discovered decomposing leaf litter from Amur honeysuckle (Lonicera maackii) and common blackberry (Rubus allegheniensis) produces chemical compounds that attracts and stimulates Cx. Pipiens female to oviposit, or lay eggs. Investigating the attractiveness and lethality of varying catch basin conditions to mosquitoes, researchers hypothesized that blackberry leaf litter could be shown to be lethal to developing mosquito larvae, and, therefore, act as a natural ecological trap for Cx. Pipiens. Five varying treatments were applied to a total 50 catch basins. Treatments included (1) all debris dredged weekly throughout the duration of the study, (2) no change to debris naturally occurring in catch basins, (3) […]

(Beyond Pesticides, November 20, 2018) Scientific conclusions used to support the registration of the insecticide chlorpyrifos were flawed and omitted key health impacts, according to a fresh analysis of the original data by a team of independent scientists from northern Europe and the U.S. This re-review not only casts further doubt on the safety of the neurotoxic chlorpyrifos, it highlights a major flaw within federal pesticide regulation that allows pesticide producers to submit their own safety evaluations to the U.S. Environmental Protection Agency without public oversight. “One conclusion we draw is that there is a risk that the results of industry-funded toxicity tests are not reported correctly,” says co-author Axel Mie, PhD. “This makes it difficult for the authorities to evaluate the pesticides in a safe and valid way.” In both the U.S. and European Union, pesticide producers contract with laboratories to perform required safety tests of active ingredients they hope to register for use. While these studies are generally considered ‘confidential business information’ and not available to the public, using Swedish freedom of information laws, researchers were able to obtain two key studies relating to the developmental neurotoxicity of chlorpyrifos. Although not disclosed within the study, it is well […]

(Beyond Pesticides, November 8, 2018) Two months after publishing its first series of tests, part two of an Environmental Working Group (EWG) study finds residues of Roundup’s active ingredient, glyphosate, in all General Mills’ Cheerios and PepsiCo’s Quaker Oats products sampled. Health advocates are expressing concern about the consequences of chronic glyphosate exposure, and say U.S. federal agencies must limit the herbicide’s use on oat-based breakfast foods regularly marketed to children. In addition, organic itself is under threat, as chemical-intensive management practices undermine the future of the growing organic movement. In this second round of testing, EWG scientists purchased products around San Francisco and Washington DC. 28 samples of conventional and 16 samples of organic oat products were collected. Approximately 300 grams of each General Mills and PepsiCo product were packaged and shipped to Anresco Laboratories, in San Francisco. Detected glyphosate residues were compared to EWG’s own health benchmark of 160 parts per billion (ppb). This benchmark is based on risks of lifetime exposure and what EWG scientists consider allowable and protective of children’s health with an adequate margin of safety.  EWG’s results detected glyphosate residues in all 28 samples of conventionally grown oat products. The vast majority (all but two) […]

(Beyond Pesticides, November 2, 2018) A group of leading toxics experts, who published a paper in the journal PLOS Medicine on their research on organophosphate exposure during pregnancy and impacts on child development, are calling for a ban on organophosphate pesticides. The study evaluates current science on the risks of this class of compounds, produced by Corteva Agriscience (formerly Dow AgroSciences); its conclusions warn of the multitude of dangers of organophosphates for children, and makes recommendations for addressing these risks. The experts conclude that: (1) widespread use of organophosphate (OP) pesticides to control insects has resulted in ubiquitous human exposures; (2) acute exposures to OPs is responsible for poisonings and deaths, particularly in developing countries; and (3) evidence demonstrates that prenatal exposures, even at low levels, put children at risk for cognitive and behavioral deficits, and for neurodevelopmental disorders. Among the authors’ recommendations are these: Governments and subsidiary agencies, including the Environmental Protection Agency (EPA), should phase out chlorpyrifos and other organophosphate pesticides; ban non-agricultural uses of OP pesticides (including in household products); monitor watersheds and drinking water sources of human exposure; promote the use of integrated pest management (IPM) through incentives and training; and establish pesticide use and illness reporting […]

(Beyond Pesticides, October 22, 2018) The California Department of Pesticide Regulation (DPR) is accepting comments on its proposal to classify chlorpyrifos as a toxic air pollutant. The classification would require DPR to develop control measures that adequately protect public health. What happens in California affects all of us because products of California agriculture are available all over the country –and the world. In addition, policies set by the state of California are often examples for other states and the federal government. Tell California Department of Pesticide Regulation to ban chlorpyrifos. California’s Office of Environmental Health Hazard Assessment (OEHHA) states: Under the Toxic Air Contaminant Identification and Control Act (AB 1807, Chapter 1047, Statutes of 1983) and its implementing regulations (Title 3, California Code of Regulations, Section 6864), one of the criteria for identifying a pesticide as a TAC is if its concentration in the air exceeds one-tenth of the level that has been determined to be adequately protective of human health. The draft TAC document shows that bystanders can be exposed to modeled air concentrations of chlorpyrifos that exceed one-tenth the protective level, and thus meet the criteria for TAC identification. OEHHA’s findings below serve to reinforce this overall conclusion, and […]

(Beyond Pesticides, October 18, 2018) Pesticide residue doesn’t announce itself –it isn’t colored, it doesn’t glow or reflect light, and after an initial application doesn’t put out a discernible odor – but it is likely ubiquitous in rural U.S. homes, according to a study published by Cornell University researchers late last month. The study is a warning specifically to households with young children, who are at increased risk of health effects from even minute levels of pesticide exposure. “Numerous health problems occur from exposure to pesticides, such as cancer, birth defects, leukemia and ocular [vision-related] toxicity, among a number of other health issues,” said Joseph Laquatra, PhD, coauthor of the research. “Households with crawling toddlers should be concerned, as toddlers will accumulate pesticide residues on their hands and then ingest them due to hand-to-mouth behaviors.” Researchers focused in on 132 households in rural counties of New York State that agreed to test for pesticide residue inside their home. Wipe samples were collected from both carpeted and non-carpeted areas, and tested for pesticides used commonly as part of agricultural production in the region. The pesticides analyzed included 15 compounds ranging from organophosphates like chlorpyrifos and malathion, to synthetic pyrethroids like resmethrin, […]

(Beyond Pesticides, October 9, 2018) In two separate moves, EPA placed the head of the Office of Children’s Health Protection on administrative leave and plans to dissolve its Office of the Science Advisor. These moves further degrade the U.S. Environmental Protection Agency’s reliance on scientific input into its decision making process. Ask your members of Congress to insist that the head of the Office of Children’s Health Protection and Office of the Science Advisor be reinstated at the highest level, The Office of Children’s Health Protection was created by President Bill Clinton in 1997 to advise EPA on meeting its mandate to protect children from environmental health hazards. Children are generally more vulnerable to toxic chemicals than adults due to their small and developing bodies and because their size and activities result in greater exposures. Focusing on children’s health typically leads to more protective regulatory decisions. Ruth Etzel, M.D., Ph.D., who was placed on non-disciplinary leave, became director of the office in 2015, after serving as a senior officer for environmental health research at the World Health Organization. She is a pediatrician and epidemiologist who has been a leader in children’s environmental health for 30 years. Recently, Dr. Etzel opposed EPA’s […]

(Beyond Pesticides, September 20, 2018) Babies exposed to higher levels of organochlorine compounds in the womb go on to have worse lung function in childhood, according to new research presented at the European Respiratory Society International Congress. Previous studies have found a link between low lung function in early adulthood and respiratory, cardiovascular, and metabolic issues in later life. Beyond Pesticides has covered in its Daily News studies on a range of adverse effects, including autism in children, caused by organochlorine pesticide exposure, which bioaccumulates in the environment and the human body. Organochlorine compounds, which include the pesticide DDT, as well as electrical insulators and other industrial products, are now banned in most parts of the world. However, because they degrade very slowly, they are still present in the environment and in foods. Previous research has suggests links between exposure to these chemicals in the womb and parents reporting childhood respiratory diseases such as wheezing, asthma, and chest infections. The new study is the first to show a link with objective measures of lung strength and capacity in relation to low-level exposure to these chemicals. Organochlorine compounds can disrupt the hormone system and have been linked to a wide range of […]

(Beyond Pesticides, August 22, 2018) Mothers with high levels of DDT’s major metabolite, DDE, are more likely to have their children diagnosed with autism, according to a study published in The American Journal of Psychiatry this month. Though this study links autism to long-banned DDT, it raises significant concerns about legacy contamination from this chemical, which remains ubiquitous in the environment and in human bodies. With an increasing number of studies linking autism and other developmental disabilities to pesticides, the need to transition to safer, organic methods of farming is now more important than ever before. The study, Association of Maternal Insecticide Levels With Autism in Offspring From a National Birth Cohort, measured maternal serum levels of Finish women during early pregnancy whose children were born between 1987 and 2005. Specimens were analyzed for DDE as well as PCB contamination. Mothers with DDE at the highest 75% threshold reportedly had a 132% (1.32x odds ratio) increased risk of having a children diagnosed with autism after adjusting for confounders such as age and history of psychiatric disorders. Moms above the 75th percentile had their chances of a child’s autism diagnosis increase by 221% (2.21x odds ratio). The study found no connection […]

(Beyond Pesticides, August 10, 2018) The U.S. Environmental Protection Agency (EPA) must ban a widely used organophosphate pesticide linked to brain damage in children, the 9th Circuit Court of Appeals ruled yesterday. The appellate court ordered EPA to finalize its proposed ban on chlorpyrifos, produced by DowDupont, based on undisputed findings that the pesticide is unsafe for public health, and particularly harmful to children and farmworkers. The ruling comes in a lawsuit brought by a coalition of labor and health organizations, represented by Earthjustice. In the absence of EPA action, states have started to stand up. In May, the state legislature in  Hawaii passed legislation, which took effect in May, to become the first state to ban the chemical. On July 30, the California Department of Pesticide Regulation (DPR) released its scientific assessment concluding that the organophosphate insecticide, chlorpyrifos, should be listed as a Toxic Air Contaminant (TAC) in the state based on evidence of its neurological effects and exposure risks of concern. Legislation is also pending in Congress to ban chlorpyrifos and similar pesticides nationwide. Chlorpyrifos is a dangerous nerve agent pesticide that can damage the developing brains of children. Prenatal and early life exposure to chlorpyrifos is linked to lower birth weight […]

(Beyond Pesticides, August 8, 2018) On July 30, the California Department of Pesticide Regulation (DPR) released its scientific assessment concluding that the organophosphate insecticide, chlorpyrifos, should be listed as a Toxic Air Contaminant (TAC) in the state based on evidence of its neurological effects and exposure risks of concern. This comes after the 2017 decision by the U.S. Environmental Protection Agency (EPA) reversed its decision to ban the dangerous chemical after intervention by its manufacturer. Decades of scientific data show that chlorpyrifos damages fetal brains and produces cognitive and behavioral dysfunctions, particularly in utero and in children. Even at low levels of exposure chlorpyrifos can impact the developing fetus in pregnant women resulting in impaired learning, change in brain functions, and alter thyroid levels of children into adulthood. A study conducted by the Columbia University Center for Children’s Environmental Health (CCCEH) found that chlorpyrifos in umbilical cord blood samples corresponded with a decrease in the psychomotor and mental development in three-year olds. Additional data collected by CCCEH researchers demonstrated that children exposed to high levels of chlorpyrifos experience developmental delays, attention deficit, hyperactivity, as well as other pervasive developmental disorders. But despite this, and the advice of the agency’s own scientists, EPA, under the direction […]

(Beyond Pesticides, July 27, 2018) The American Academy of Pediatrics (AAP) has issued new guidelines for measures to lower children’s exposures to chemicals in food and food packaging that are tied to health problems such as obesity, metabolic changes, decreased birth weight, and endocrine disrupting effects, including reduced fertility. Exposures to these chemicals–added to food during processing or in food packaging–are disproportionately high among minority and low-income populations, according to the report, especially given inadequate federal regulation and oversight. The guidelines, issued in both a statement and technical report by the AAP entitled, Food Additives and Child Health, came after the group decided to review and highlight emerging child health concerns related to “the use of colorings, flavorings, and chemicals deliberately added to food during processing (direct food additives) as well as substances in food contact materials.” Food additives, in particular, have been documented to be linked to endocrine disruption and other adverse health effects. According to AAP, “regulation and oversight of many food additives is inadequate because of several key problems in the Federal Food, Drug, and Cosmetic Act. Current requirements for a “generally recognized as safe” (GRAS) designation are insufficient to ensure the safety of food additives and do not […]

(Beyond Pesticides, May 17, 2018)  Among the many reports of the salutary effects of nature on human health and well-being comes new research demonstrating that children who live in “green” neighborhoods have reduced risk of developing asthma. Researchers Jeroen Douwes, PhD and Geoffrey H. Donovan, PhD, of New Zealand’s Massey University (Centre for Public Health Research) and the U.S. Forest Service, respectively, conducted the longitudinal study with New Zealand subjects born in 1998, following them until 2016. The authors say the study results “suggest that exposure to greenness and vegetation diversity may be protective of asthma.” Of concern are the pesticides used in green spaces. See Beyond Pesticides’ brochure, Asthma, Children, and Pesticides and El Asma, los Niños y los Pesticidas: Lo que usted debe saber para proteger a su familia. Also, see Children and Pesticides Don’t Mix. In addition to the well-substantiated benefits of exposure to nature — reduction of the experience of stress; reduction in production of cortisol (the “stress” hormone that is linked to weight gain, hypertension, cardiac disease, weakened immune function, and loss of bone density); improved mental health; better cognitive function; and lower  BMI (body mass index) — this latest research evaluates the impact on children’s risk for asthma.

(Beyond Pesticides, May 3, 2018) Hawaii’s bill to ban the dangerous, neurotoxic pesticide, chlorpyrifos, passed its final hurdle this week in the state legislature. Governor David Ige is expected to readily sign SB3095 into law, in light of the unanimous support it received from lawmakers on both sides of the aisle. The statewide prohibition of chlorpyrifos will take effect beginning in January 2019. This legislative action marks the first time that any state in the country has passed an outright ban on the highly toxic organophosphate pesticide. While multiple scientific studies have determined that chlorpyrifos damages fetal brains and produces cognitive and behavioral dysfunctions, particularly in utero and in children, states have been slow to institute a complete prohibition, due to its widespread use in agriculture. Lawmakers in New Jersey and Maryland have recently tried unsuccessfully to pass similar bans. Hawaii’s bill contains a caveat that allows the state’s Department of Agriculture (DOA) to grant special permits for companies that argue that they need more time to phase-out chlorpyrifos, but that exemption will end at the close of 2022. The new law also requires restricted use pesticide (RUP) users to report to the Hawaii’s DOA which ones they are applying on […]

(Beyond Pesticides, March 21, 2018) According to a new study published this month in Environment Health, women with high levels of glyphosate in their bodies are more likely to have shorter pregnancies. Shorter pregnancies can lead to children with reduced learning and brain development. This is the first study to suggest that exposures to glyphosate can influence the long-term well-being of children. The study, Glyphosate exposure in pregnancy and shortened gestational length: a prospective Indiana birth cohort study, obtained both urine and drinking water samples from 71 women with pregnancies living in Central Indiana while they received routine prenatal care, and analysed the relationships of glyphosate levels in mother’s urine with fetal growth indicators and gestational length. The researchers found that more than 90 percent of pregnant women had detectable levels of glyphosate where higher glyphosate levels were significantly correlated with shortened gestational lengths, even though the drinking water samples had little to no detectable levels of glyphosate. Women living in rural areas were found to have higher glyphosate levels. The authors note their study is significant because it is the first U.S. study designed specifically to measure prenatal glyphosate exposure in pregnant women to determine its association with adverse fetal […]

(Beyond Pesticides, October 5, 2017) Research published in the International Journal of Cancer links the residential use of pesticides to an increased risk of childhood brain tumors in children. According to the study, mothers who use pesticides in the home while pregnant put their children at 1.4 times the risk of developing a brain tumor under the age of 15. The study findings point to the need to eliminate the residential use of toxic chemicals by increasing education around alternative pest management practices in the home and garden, as well as regulatory action to remove toxic pesticides from the market. The team of researchers used data drawn from population-based, case-control studies conducted in France, ESCALE and ESTELLE, which investigated the role of infectious, environment, and genetic factors in common cancers (leukemia, lymphoma, neuroblastoma, and brain tumors). From the data, researchers identified 3,102 control mothers, and 437 mothers whose children had developed a brain tumor. These mothers were interviewed via phone over their use of pesticides in and around the home during their pregnancy. Scientists determined that use of pesticides in the home put children at 40% increased risk of brain tumors, with insecticides being specifically linked to this increase. Because […]

(Beyond Pesticides, October 2, 2017) Elementary school students at New York City’s PS 290 are taking a stand against toxic pesticide use in New York City parks, supporting Intro 800, a bill introduced by Manhattan Councilmember Ben Kallos. “We’re going to make a great big fuss,” the children in Mrs. Paula Rogivin’s kindergarten class chanted in a skit performed in front of the NYC Committee on Health this week. Since New York City (NYC) passed Local Law 37, Pesticide Use by City Agencies, in 2005 to stop toxic pesticide use on City owned and leased land, it turns out that some pesticides known to be hazardous were not captured by the law. As a result, the proposed legislation is intended to strengthen restrictions to ensure more comprehensive restrictions that limit pesticides to biological pesticides. Local Law 37 restricts the use of acutely toxic and carcinogenic pesticides as defined by the U.S. Environmental Protection Agency (EPA), and developmental toxicants as defined by the state of California under Prop 65. Exemptions allowing the use of these pesticides are granted based on a waiver review process that requires evidence that the chemicals are necessary to protect public health. Otherwise, City agencies are encouraged […]

(Beyond Pesticides, September 18, 2017) Ask California to ban the neurotoxic pesticide chlorpyrifos that’s on the food we eat from California –since the administrator of EPA refused to take the action agency scientists said is necessary to protect children. Tell California to ban chlorpyrifos! In view of EPA’s retraction of its proposal to revoke food residue tolerances of the highly neurotoxic insecticide chlorpyrifos, despite its own assessment that the chemical is too toxic to children, it is especially important that California take action to ban the chemical. California, the home of the largest agriculture industry in the country, used over 1 million pounds of chlorpyrifos on over a million acres in 2012. EPA’s assessment is also support for the classification of chlorpyrifos as a developmental toxicant, an issue being considered on a parallel track by California’s Office of Environmental Health Hazard Assessment (OEHHA), which oversees the “Prop 65” list. EPA’s assessment, which incorporates recommendations from a 2016 Scientific Advisory Panel (SAP), finds that children exposed to high levels of chlorpyrifos have mental development delays, attention problems, attention-deficit/hyperactivity disorder problems, and pervasive developmental disorders. The SAP agreed with EPA that there is an association between chlorpyrifos prenatal exposure and neurodevelopmental outcomes in children. […]
