(Beyond Pesticides, February 26, 2014) The French agriculture ministry is prosecuting Emmanuel Giboulot, an organic winemaker, for failing to apply insecticide to his vines. The ministry wants insecticide to be sprayed to control the leafhopper Scaphoideus titanus, believed to be responsible for the spread of the grapevine disease, but Mr. Giboulot believes the pesticide is ineffective and damaging to pollinating insects such as bees, and insists the disease can be fought via more natural means. Emmanuel Giboulot appeared before a judge in the city of Dijon on Monday after defying an official order to treat his vineyard against an insect suspected of transmitting a devastating plant disease, and risks six months in jail for failing to take preventive measures against a bacterial vine disease. He was fined €1,000 for putting neighboring vineyards at risk. The court’s final verdict will be announced on April 7. Mr. Giboulot, an organic and biodynamic winemaker, was found to be in violation of a directive to use pesticides to fight Flavenscence dorée, an infectious disease spread by the leaf hopper, Scaphoideus titanus that threatens the Côte-d’Or region of Burgundy. An estimated 30 acres of vines were destroyed by the disease in 2012. “Would we give […]

(Beyond Pesticides, February 10, 2014)    A recent study has found that exposure to pyrethroids is increasing among children and adults. The study also finds that children are still widely exposure to chlorpyrifos, an organophosphate chemical that has been banned for household use for over 12 years. This is not the first study to find high concentrations of pyrethroids in residential, but it may be the first to evaluate correlations between pesticide dust concentration and concentration of pesticides in children’s urine. The study, Urinary Pyrethroid and Chlorpyrifos Metabolite Concentrations in Northern California Families and Their Relationship to Indoor Residential Insecticide Levels,  conducted by researchers at the University of California, Davis, analyzed urine samples from 90 adults, 83 children, and 88 floor wipe samples from participants’ kitchen floors. The participants were 90 northern Californian families who had children born between 2000 and 2005, with the samples collected from 2007-2009.   These samples were analyzed for concentrations of pyrethroids, pyrethroid metabolites, chlorpyrifos, and chlorpyrifos metabolites.  The study found pyrethroid metabolites in 63 percent of all urine samples with concentrations twice as high as levels reported in a national 2001-2002 study. In children, higher concentrations of pyrethroids found in floor wipes were associated […]

(Beyond Pesticides, January 22, 2014)  Exposure to a widely used pesticide causes worker bumblebees to grow less and then hatch out at a smaller size, according to a new study by Royal Holloway University of London. The research, published this week in the Journal of Applied Ecology, reveals that prolonged exposure to a pyrethroid pesticide, which is used on flowering crops to prevent insect damage, reduces the size of individual bees produced by a colony. The researchers, Gemma Baron, Dr Nigel Raine and Professor Mark Brown from the School of Biological Sciences at Royal Holloway worked with colonies of bumblebees in their laboratory and exposed half of them to the pesticide. The scientists tracked how the bee colonies grew over a four month period, recording their size and weighing bees on micro-scales, as well as monitoring the number of queens and male bees produced by the colony. “We already know that larger bumblebees are more effective at foraging. Our result, revealing that this pesticide causes bees to hatch out at a smaller size, is of concern as the size of workers produced in the field is likely to be a key component of colony success, with smaller bees being less […]

(Beyond Pesticides, December 10, 2013) A former steward for Australian-based Quantas airlines is suing the Australian government claiming that frequent insecticide use in airplane cabins resulted in his Parkinson’s disease diagnosis. Australia is among 49 countries that require pesticide spraying on some or all flights. Pesticide use on flights into the United States is not required, but is permitted under international law. (See here for a breakdown of pesticide use in American-based airlines, and here for information from the U.S. Department of Transportation on pesticide use in aircrafts.) Brett Vollus, former Quantas airline steward, worked for the company for 27 years until this past May when he was diagnosed with Parkinson’s and a malignant brain tumor. “He [my doctor] asked me what I did for living and when I told him he just nodded and said: ‘Another one, I am seeing a lot of you’,” Mr. Vollus said to The Australian. “This is a nightmare that has ruined my life. I am very keen to start a legal action and if it can help others I am happy to lead the way.” This case puts an international spotlight on growing evidence that pesticide use is linked to Parkinson’s disease. Parkinson’s […]

(Beyond Pesticides, November 27, 2013) You can almost taste it: the moist, tender turkey, the fluffy mashed potatoes, the creamy green bean casserole, the perfectly seasoned stuffing, the roasted brussel sprouts sprinkled with salty bacon, the sweet tang of the cranberry sauce, and the velvety bite of the pumpkin pie. Thanksgiving and all its bounty is almost here. Of course, the impending feast doesn’t magically appear. Whether you have merely observed the bustle of preparation, assisted with the pealing and chopping, or orchestrated the entire affair, it is well known that the hard work of many lies behind the tantalizing spread. And if your Thanksgiving tradition is like most gatherings across the nation, before you carve the turkey, scoop the mashed potatoes and stuffing, serve up the salad, and ladle the gravy all over your plate, there is a moment of pause. Be it in the form of prayer, song, or simple sharing, it is a moment honoring the purpose for this great celebration. It is a moment to stop and be grateful for the bounty before you and the friends surrounding you. It is a moment to give thanks for the hard work of those who prepared the great […]

(Beyond Pesticides, November 1, 2013) Insecticides commonly used in homes and schools are associated with behavioral problems in children, according to a recent study by Canadian researchers. The study investigates exposure to pyrethroid pesticides, used in more than 3,500 products, including flea and tick controls, cockroach sprays, and head lice controls. The study, Urinary metabolites of organophosphates and pyrethroid pesticides and behavioral problems in Canadian children, published in the journal Environmental Health Perspectives, raises serious concerns about the impact of pyrethroids, which are increasingly used as a replacement for organophosphates. This study uses data from the Canadian Health Measures Survey (2007-2009), a nationally representative survey, so researchers are able to apply these findings to the entire population of Canadian children. In a previous study among U.S. children, researchers at the National Health and Nutrition Examination Survey (NHANES) examined the metabolites of pyrethroids in children below the age of six. Similarly, they found pyrethroid insecticides in more than 70 percent of the samples, concluding that children had significantly higher metabolite concentrations than those of adolescents. Together these studies demonstrate that exposure is widespread, with real impacts to human health. In the recent study, researchers analyzed organophosphate and pyrethroid metabolites in the […]

(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 3, 2013) For the past several years, corn rootworms  have  been widely reported to exhibit resistance  to corn genetically engineered (GE) with the Bacillus thuringiensis (Bt) toxin. A  new report by  University of Illinois researchers found the resistant corn rootworm  in two of the state’s counties significantly damaged by western corn rootworm. The increasing lack of efficacy of GE corn, developed with the claim that it  is specifically designed to protect corn from rootworm, calls into question the efforts of agrichemical companies to patent new forms of GE crops. The report by Joe Spencer, PhD, and Michael Gray, PhD,  identifies significant damage from western corn rootworms in farm field that were planted with GE corn that contain a Bt protein referred to as “Cry3Bb1,” which has been inserted into nearly one-third of the corn planted in the United States. This version of Bt corn was introduced by Monsanto in 2003, and was touted as a way to reduce insecticide use against rootworm pests. Evidence was gathered in two Illinois counties, Livingston and Kankakee, after fields that had severe root pruning and lodging were brought to the attention of Drs. Spencer and Gray. Dr. Gray was quoted in […]

(Beyond Pesticides, August 26, 2013) A recent study presented by the Centers for Disease Control and Prevention (CDC)   at the International Conference on Lyme Borreliosis and other Tick-Borne Diseases in Boston finds that spraying lawns with the insecticide bifenthrin does not reduce the incidence of tick-borne diseases. The study could have important policy implications for towns and communities that are feeling pressure to spray as prevalence of tick-borne diseases, such as Lyme disease, continue to rise.  There are least-toxic alternative management strategies that are effective and safer than chemical controls. The recently released study by CDC included 2,500 households in Fairfield, Litchfield, and New Haven Counties in Connecticut; Dutchess County in New York; and four counties in Maryland. Half of the households’ lawns were sprayed with bifenthrin and the other half was sprayed with water as a control. The study, conducted over two years, found that the households that were sprayed with bifentrhin saw a 60 percent reduction in ticks on their propriety but still had similar levels of tick encounters and tick-borne illnesses. These final results are similar to the results the study found after its first year.   This research reveals that using pesticides is not an […]

(Beyond Pesticides, July 29, 2013) Researchers at the U.S. Department of Agriculture (USDA) and University of Maryland have found that low levels of pesticide exposure from crop pollination make honey bees more susceptible to the deadly gut parasite, Nosema ceranae, contributing to declines in bee populations. The study’s findings, released Wednesday July 24 in the journal PLoSONE, expand on a recent report released by the USDA that found parasites, disease, genetics, poor nutrition, and pesticide exposure as synergistic factors in the observable nationwide honey bee decline, but focused on technological stopgap measures without questioning the  sustainability of widespread systemic neonicotinoid pesticide use.  Adding urgency to USDA’s research, another study released just last Monday in the Proceedings from the National Academy of Sciences shows that pollinator losses can have a detrimental effects on plant reproduction. Pesticide Exposure and Susceptibility to Disease The newest USDA research adds to the growing body of evidence that shows pesticide exposure weakens honey bees’ immune system making them more susceptible to parasites and pathogens. Researchers took pollen samples from crops that honey bees are known to pollinate including apples, watermelons, pumpkins, cucumbers, blueberries, and cranberries to determine exposure levels and Nosema infection. In sum, researchers found […]

(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, 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 […]

(Beyond Pesticides, May 22, 2013) Norwegian seafood production company, Marine Harvest, has committed to certify its salmon farms by 2020  to the Aquaculture Stewardship Council (ASC) Salmon Standard, with the condition that they  begin tightening restrictions of pesticide use and move from caged systems in coastal waters to closed containment systems. As the world’s largest producer of farmed salmon, responsible for 25% to 30% of the global salmon and trout production the move marks an important shift toward sustainable production of their fish products. The ASC Salmon Standard, an accreditation scheme developed and promoted by the World Wildlife Fund (WWF), requires members to  diminish the use of toxic chemicals, address sourcing of feed ingredients, diminish the transmission of disease to wild salmon populations, control the escape of farmed salmon, reduce the use of antibiotics and genetically engineered products, and finaly address the labor issues on salmon farms. As of now Marine Harvest has only committed to accredit its fish farms within the United Kingdom, although they also produce fish in Norway, Canada, the Faroe Islands, Ireland and Chile. The company’s move follows on the heels of recent media attention that revealed the Scottish Environmental Protection Agency (Sepa) had  found up […]

(Beyond Pesticides, May 21, 2013) The Centers for Disease Control (CDC) recently concluded that 2012 was the deadliest year for West Nile Virus (WNv) in the United States. “A total of 5,674 cases of West Nile virus disease in people, including 286 deaths, were reported to CDC from 48 states (excluding Alaska and Hawaii),” said the CDC in a statement. While it is still too early to determine whether this year will be as bad as last year’s outbreak (experts say the largest disease outbreaks  is strongly driven by weather patterns characterized by hot wet summers), one thing is certain: There are simple mosquito control techniques that can be performed in your community and backyard that will prevent the spread of WNv and nuisance biting mosquitoes without the use of highly toxic pesticides. Beyond Pesticides fielded calls from concerned residents across the U.S. whose communities were doused with pesticides in attempts to control WNv. Yet, these controls have been shown to be ineffective at managing mosquito populations. According to David Pimentel, PhD, professor emeritus of entomology at Cornell University, less than .0001% of adulticides (mosquito insecticides) reach target adult mosquitoes. Dr. Pimentel notes, “Thus by both ground and aerial application […]

(Beyond Pesticides, April, 23, 2013) A report released by the Surface Water Ambient Montioring Program (SWAP) has found in California that “detection of pyrethroid pesticides in sediment increased from 55 percent of the statewide samples in 2008 to 85 percent in 2010.” The findings are among the results of the Stream Pollution Treads, or SPoT, monitoring program, an annual assessment of pollution in streams in California. The report also found that stream beds in urban areas have higher levels of pyrethroids that those in agricultural areas. The SWAP report summarizes results of the 2009 and 2010 annual surveys and compares those results to the 2008 SPoT data. Beyond the 30 percent increase of pyerthriods detected in sediment, the percentage of highly toxic samples increased from 6 percent to 67 percent when toxicity tests were conducted at a colder temperature that more closely matched the normal surface water temperature in average watersheds. These results, according to the report, “suggest that current monitoring may underestimate the occurrence of parathyroid-associated toxicity using the standard protocol.”   The report also acknowledges that some pyrethroids, such as bifenthrin, may persist longer than others, and the chronic impacts of these pesticides may be underestimated by some […]

(Beyond Pesticides, March 26, 2013) Scientists are learning more about the mechanisms bed bugs have developed to increase their resistance to the increasingly common class of pyrethriod pesticides. The study, published in the journal Scientific Reports in early March, adds further weight to calls from consumer health and environmental groups to adopt proven, non-toxic strategies to manage bed bugs and other household pest problems. After all, if alternatives exist, why put your family at risk with unsustainable, ineffective control methods? This latest research reveals something scientists had not suspected. Bed bugs are developing most of their resistance-associated genes on the outer layer of their shell. These genes either neutralize the insecticides before they can take effect, or slow down the toxins’ move towards the insects’ nerve cells. In addition, bed bugs in the study also show resistance developing within their nerve cells, the target site for the pesticides. This multilayered resistance is unique, scientists say, but, as Beyond Pesticides has long documented, pest resistance to pesticides is not. A 2011 study from Ohio State University reveals bed bugs’ ability to evolve hereditary changes in their production of certain enzymes, allowing them to excrete the toxins without being harmed. A study […]

(Beyond Pesticides, March 1, 2013) In a literature review published in Toxicology last week, researchers found that environmental and occupational pesticide exposure was strongly associated with declines in sperm count. Researchers Sheena Martenies, BS, and Melissa Perry, ScD., MHS., determined that of the 17 studies evaluated, 15 of them reported significant associations between pesticides and semen quality. The researchers counted semen quality according to concentration of sperm over an area, their motility and ability to move, as well as their shapes. Researchers targeted studies on DDT, HCH, and abamectin, grouping pyrethroids and organophosphates by class. What they found was striking: almost all the studies reported a decrease in sperm concentration; decreased motility was also reported though less frequently; while morphological changes were not strongly associated in studies””only two indicated any changes to sperm shape. These findings build on a growing body of evidence that pesticide exposure at environmental or occupational levels diminished sperm health. In addition to the U.S. findings,  studies conducted on French, New Zealander, Indian, Tunisian, and Israeli men have all found decline in sperm count. Some studies record a drop by approximately 50% between 1940 and 1990, no small amount. These results might not be surprising as […]

(Beyond Pesticides, January 31, 2012) A new study finds that a mother’s exposure to pesticides before, during and after pregnancy may increase the risk of infant leukemia diagnosed before the age of two. Researchers in Brazil found that children are twice as likely to develop the rare cancers if their mothers were exposed three months before conception when compared to mothers who reported no exposures. A mother’s exposure at any time to the insecticide permethrin also raised the cancer risk for infants. The results support recommendations for women of reproductive age to minimize their pesticide exposure before and during pregnancy and while breastfeeding, and adds to the growing weight of evidence of the dangers of using synthetic pyrethroid pesticides. The study, entitled, “In utero pesticide exposure and leukemia in Brazilian children less than 2 years of age,” is published in Environmental Health Perspectives. Researchers asked mothers in Brazil about their pesticide exposure three months before pregnancy, while pregnant and three months after pregnancy when they were nursing. The women reported their home, work and agricultural contact with pesticides (at least once) between 1999 and 2007. Pesticide exposures from mothers of 252 children younger than two years old and diagnosed with […]

(Beyond Pesticides, September 12, 2012) Expectant mothers exposed to the pesticide additive piperonyl butoxide (PBO), widely used in synthetic prethroid insecticides and those ending in “thrin” (popular in mosquito spray programs), during pregnancy pass to their children a heightened risk of noninfectious cough at ages 5 and 6, according to researchers at the Columbia Center for Children’s Environmental Health (CCCEH). These findings support the premise that children’s respiratory system is susceptible to damage from toxic exposures during the prenatal period. Researchers outfitted 224 expectant mothers with air monitors during their third trimester of pregnancy and measured the levels of PBO and permethrin in the air around them. Then, once the children were 5 and 6, the same two chemicals were measured from air samples collected inside their home. Results showed that children exposed to PBO in the womb were at increased odds of reporting cough unrelated to cold or flu. Researchers found no correlation between prenatal or childhood exposure to permethrin, however they pointed out that this may be because PBO is easier to measure in air samples than permethrin. Coauthor of the study, “Prenatal exposure to pesticide ingredient piperonyl butoxide and childhood cough in an urban cohort,” Dr. Rachel […]

(Beyond Pesticides, August 20, 2012) Given the number of West Nile virus (WNv) cases, including 26 deaths, it is important to focus attention on mosquito management methods that are the most effective and do not introduce additional short- and long-term public health hazards with the use of toxic pesticides, public health advocates say. It is understandable that local, state, and federal officials want to act decisively, but that does not mean that the widespread use of hazardous pesticides is the best course of action, according to Beyond Pesticides, a national information and advocacy organization on pesticides and alternatives based in Washington, DC. According to Beyond Pesticides’ executive director, Jay Feldman, “Communities that are most successful and smart about mosquito control engage in aggressive efforts to reduce and eliminate mosquito breeding areas in standing water around homes and buildings and throughout the community.” Mosquito breeding can take place in stagnant water, from very small to larger pools —bottle caps, discarded automobile tires, planters, containers, rain gutters, drains, or under piles of leaves. The widespread spraying of toxic pesticides (typically chemicals known as synthetic pyrethroids, organophosphates, or other nervous system poisons) does not provide a long-term sustainable solution to mosquito control. “It […]

(Beyond Pesticides, July 27, 2012) A Connecticut state Department of Energy and Environmental Protection study has detected residues of mosquito control pesticides in lobsters pulled from Long Island Sound. Using new testing technology that can detect small concentrations of substances, ten lobsters were tested for three common mosquito control chemicals: malathion, methoprene, and resmethrin. Positive results were found in the organ tissue of one lobster for methoprene and three lobsters for resmethrin. The results present the first scientific evidence that pesticides may be affecting lobsters in the Sound and are likely to further anger the Connecticut lobstering industry which, for years, has been pointing to mosquito pesticides as a likely cause of a serious decline in the lobster population of the Sound, but has been met with resistance. Late summer declines in the Sound’s lobster population have been alarmingly common throughout much of the last decade, devastating fishers and the local economy that depends on them. A number of factors have been blamed, but the lobstering community has increasingly been pointing to mosquito pesticides for several reasons. Some, such as methoprene, have a tendency to sink to the bottom of the ocean water, where lobsters live and feed. Additionally, lobsters […]

(Beyond Pesticides, June 27, 2012) One county in New Jersey is getting serious about combating mosquitoes this season. Instead of relying on pesticide spraying, which has been shown to not be effective, the Cape May County Department of Mosquito Control is employing 10,000 tiny shrimp-like crustaceans that will eat their way through mosquito larvae in the county’s swamps, roadside ditches and small pools. The latest weapon in the battle against mosquitoes is barely visible. The crustaceans, known as copepods, are cousins to crayfish and water fleas, and do not get much bigger than two millimeters. They are voracious predators of mosquito larvae. New Jersey recently delivered 10,000 of the tiny shrimp-like crustaceans to Cape May County. They are already being used to fight mosquitoes in Bergen, Passaic, and Morris counties. Ocean County is next on the delivery list and six other counties will follow. “The days of driving a truck down the street and spraying pesticides are long gone. These copepods can pick up where fish leave off,” according to Administrator Robert Kent, of the state Office of Mosquito Control. Natural Predators as a Solution for Mosquito Control New Jersey has used mosquitofish, fathead minnows, killifish, bluegill and other fish […]

(Beyond Pesticides, June 21st, 2012) A new study details the toxic effects of long-term exposure to commonly used agricultural pesticides. Results indicate an increased likelihood of moderate to severe blood toxicity and a reduced total number of bone marrow cells, which can lead to degenerative diseases like aplastic anemia. The study, entitled “Pesticide Induced Alterations in Marrow Physiology and Depletion of Stem and Stromal Progenitor Population: An Experimental Model to Study the Toxic Effects of Pesticide” is published in the online version of the Journal of Environmental Toxicology . The experiment, led by researchers at the Calcutta School of Tropical Medicine’s Department of Biochemistry and Medical Biotechnology, exposed a group of mice to a mixture of organochlorine, organophosphate and pyrethriod pesticides, including a preponderance of the chemicals cypermethrin, and chloropyrofos. The exposed mice showed an overall reduction in the ability of their bodies to produce bone marrow cells. Bone marrow, the soft flexible tissue found in the interior of bones, is a storehouse for stem cells. While the exact mechanism is unknown to researchers, the study reveals that the microenvironment in which stem cells develop is somehow deranged by pesticides. This derangement prevents the maturation of stem cells into every […]
