(Beyond Pesticides, October 18, 2012) A new study pinpoints agricultural pesticides and fertilizers as the likely culprit for an incurable and deadly kidney disease that has afflicted thousands of Sri Lankans. As many as 400,000 people in the north-central region of Sri Lanka may be affected by the chronic kidney disease (CKD), and as many as 22,000 people may have died over the last two decades as a result. “The reason for the spread is heavy metals in the water caused by the unregulated use of fertiliser and pesticides,” Dr. Channa Jayasumana, from the Faculty of Medicine at the Rajarata University in Anuradhapura, told Inter Press Service News Agency (IPS). The World Health Organization (WHO) and the Sri Lankan government launched an investigation four years ago, testing the local environment and taking blood, urine and tissue samples. The results, which were released this summer in a one-page press release, pointed to cadmium and arsenic. Though cadmium is found in fertilizers, it is illegal to use arsenic-based pesticides in Sri Lanka. Dr. Jayamasumana is one of the doctors that has been engaging in research activities in the epidemic of CKD, and told Beyond Pesticides that they strongly believe that the main […]

(Beyond Pesticides, October 16, 2012) The Oregon Department of Agriculture (ODA) is looking to revamp the way it enforces the 1993 Agricultural Water Quality Management Act in order to decrease the amount of pesticides that end up in the state’s waterways from agricultural nonpoint source pollution. The new plan, which was unveiled last December, will work by taking a firmer approach than the current plan, which on sporadic complaints for enforcement and cooperative action by residents through soil and water conservation districts. While a new plan could benefit the health of Oregon residents and its waterways, it is in danger because politicians and some farmers believe it will be overly burdensome and increase costs. Oregon is no stranger to problems with pesticide contamination of its water. The state of Oregon has a complex and diverse agricultural economy which ranges from forestry products to seed crops. Oregon also has thousands of miles of waterways. Roughly 15,000 miles of these waterways are listed as impaired, and nearly half of the 11,000-plus miles of waterways in Willamette River basin need more streamside plants, according to a 2009 state report. These plants help reduce the amount of run off by reducing the amount of […]

(Beyond Pesticides, October 12, 2012) After reading several cases of pesticide poisonings throughout the state of Utah, State Senator Gene Davis (D-Utah), has announced plans to sponsor legislation that requires notification when nearby homes are being treated with toxic pesticides. Pre-notification is a critical step in the right direction to allow people to avoid unwanted chemical exposures. Utah’s current pesticide notification system is voluntary. While pesticide applicators are required to alert their customers of the dangers associated with certain pesticides they apply, residents are not required currently to notify their neighbors when they apply pesticides around their home. One recent case to come to light is the Pammi family’s loss of their golden retriever “Rusty” (see image) that they attribute to the toxic herbicides he inhaled after they were applied on their neighbor’s lawn this August. Rusty ingested the product TruPower3, a potent mixture of 2,4-D, mecoprop-p (MCPP-p), and dicamba. Beyond Pesticides was in contact with Mrs. Pammi after the incident, and although there is no way to confirm that Rusty’s death was the result of pesticide exposure, Ms. Pammi provided Beyond Pesticides with this statement from Rusty’s vet: “The herbicide Trupower, which contains a mixture of 2,4-D, mecoprop-p and […]

(Beyond Pesticides, October 11, 2012) A new report highlights the growing body of research that links pesticides to the rampant rise of learning disabilities, childhood cancer and asthma in the United States, and calls for swift policy change to protect future generations. In particular, the report points out that children are more sick today than they were a generation ago, confronting serious health challenges from pesticides and other chemical exposures that their parents and grandparents were unlikely to face. This report underscores the importance of changing the individual chemical assessment approach to regulating pesticides, and integrating a systems approach that incorporates organic principles that strive to eliminate unnecessary pesticide use. The report entitled, A Generation in Jeopardy: How pesticides are undermining our children’s health and intelligence was released by Pesticide Action Network North America (PAN). It draws from academic and government research, focusing on studies published within the past five years, to chronicle the emerging threat of —with over 1 billion pounds applied on farms and homes annually— to children’s health. Children and other sensitive sub-populations are exposed to a “toxic soup” of chemicals whose health impacts are not properly understood and clouded in uncertainties which are not captured in […]

(Beyond Pesticides, October 9, 2012) Sewage sludge is big business in Channahon, IL, but many residents who live near fields treated with the fertilizer believe they’re the ones paying the price. Farms in the area began applying the “biosolids” in 2010, and residents say that’s when their health issues began, according to Morris Daily Herald. Biosolids, otherwise known as sewage sludge, are composed of dried microbes previously used to process wastewater in treatment plants. The material is increasingly being used in conventional agriculture, but its application is explicitly forbidden in organic production. This is because the sludge can contain high concentrations of toxic contaminants, such as pesticides, detergents, estrogenic hormones, antibiotics, dioxins, PCBs, flame retardants, and heavy metals. Past research gives credence to Channahon residents’ claims of adverse health effects as a result of living near sludge coated fields. A 2002 study revealed the material to be associated with an increased prevalence of Staphylococcus aureus infections, a condition known to cause skin rashes and respiratory problems, for people located in close proximity to biosolid application sites. “What they are doing is making a toxic dump of our area. It’s disgusting,” said Channahon resident Pat Budd in an interview with Kris […]

(Beyond Pesticides, October 5, 2012) Researcher Paul Kendra of the Agricultural Research Service’s Subtropical Horticulture Research Station and others are investigating natural essential oils as traps for Red Bay Ambrosia beetles, the primary vector of laurel wilt fungus, which attacks trees, including avocado trees in the southeastern U.S. Building on previous research, the researchers have identified two important oils, phoebe oil and manuka oil, as potent antifungal agents that can be applied to avocado trees. They have gone so far as to start shipping fungicide-treated avocado trees from the Miami avocado germplasm collection to disease-free sites. The invasive beetle from Asia has spread to the Carolinas, Florida and west to the Mississippi, killing 90 to 95 percent of infected trees and significantly altering forest ecosystems. Scientists are concerned that the beetles will soon reach Mexico and California, which are major avocado production areas. If only half of California’s commercial avocado trees died, estimates indicate it would mean a total economic impact of about $27 million. In response to growing concerns, the U.S. Department of Agriculture (USDA) is researching alternative strategies to monitor and eventually control the spread of the ambrosia beetle. Both manuka oil and phoebe oil are sourced from […]

(Beyond Pesticides, October 3, 2012) A study published this week by Washington State University’s research professor Charles Benbrook, PhD, finds that the use of herbicides in the production of three genetically engineered herbicide-tolerant crops -cotton, soybeans and corn- has actually increased, contrary to industry claims that the technology would reduce pesticide applications. While Dr. Benbrook’s analysis is the first peer-reviewed, published estimate of the impacts of genetically engineered (GE) herbicide-tolerant crops on pesticide use, scientists have been raising the alarm over the mounting numbers of herbicide resistant weeds. This herbicide resistance finding, which contradicts chemical industry claims, is based on an exhaustive analysis of publicly available data from the U.S. Department of Agriculture’s National Agriculture Statistics Service. In the study, “Impacts of genetically engineered crops on pesticide use in the U.S. — the first sixteen years,” which appears in the peer-reviewed journal Environmental Sciences Europe, Dr. Benbrook writes that the emergence and spread of glyphosate-resistant weeds is strongly correlated with the upward trajectory in herbicide use. Marketed as Roundup and other trade names, glyphosate is a broad-spectrum systemic herbicide used to kill weeds. Approximately 95 percent of soybean and cotton acres, and over 85 percent of corn, are planted to […]

(Beyond Pesticides, October 2, 2012) The herbicide atrazine may be linked to an amplified risk of choanal atresia, a congenital abnormality of the nasal cavity, according to researchers at Baylor College of Medicine and other Texas institutions. Choanal atresia is recognized when tissue formed during fetal development blocks an infant’s nasal cavity. Though it is a rare condition, it is considered quite serious because it can affect an infant’s ability to breathe. The study, scheduled for publication in The Journal of Pediatrics, focused on atrazine because, although there are very few risk factors for choanal atresia, endocrine disrupting chemicals are suspected to be associated with the condition. “Endocrine disrupters aren’t fully understood, but it is believed they interfere with or mimic certain hormones, thereby blocking their proper function and potentially leading to adverse outcomes,” said Dr. Phillip Lupo, lead author of the study. Looking at mothers from Texas counties with the highest levels of estimated atrazine application, researchers discovered that they are 80 percent more likely to have children with choanal atresia or stenosis (a less severe form of the condition) than compared to mothers who live in counties with the lowest levels. The herbicide atrazine and over 50 other […]

(Beyond Pesticides, September 25, 2012) According to a report from New York City’s Department of Health, Roundup, Monsanto’s most popular and widely used product is also the most frequently applied herbicide in the city. This has occurred in violation of the spirit and intent of the 2005-passed the Pesticide Useage Law (Local Law 37), which put New York City on track to eliminate dependency on hazardous pesticides, and submit a city integrated pest management (IPM) plan to the mayor every January. The report, Pesticide Use by New York City Agencies in 2011, indicates that over 500 gallons of Roundup in various formulations was applied to city ground in the year 2011. While the city is required to report on the total amount and number of herbicide applications, according to an article from Mother Jones, information on the location of these applications is harder to come by. “Parks also declined my request for a sample of the warning sign or safety protocols that it posts around areas where Roundup is sprayed, though signs from previous years noted that Roundup applications, at sites like Central Park’s Turtle Pond and Metropolitan Museum grounds, were done at 4 a.m. Parks didn’t answer my question […]

(Beyond Pesticides, September 21, 2012) A new French study reports that rats fed a diet of Roundup-tolerant genetically modified (GM) corn had an increased risk of developing tumors, suffering organ damage and dying prematurely. The study is the first animal feeding trial studying the lifetime effects of exposure to Roundup tolerant GM corn and has prompted the European Food Safety Authority to look into the study’s results. However, it is also being criticized by some other scientists who said the methodology was flawed and that other research had not found similar problems. The study, “Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize,” which is being published in the peer-reviewed journal Food and Chemical Toxicology, was led by Gilles-Eric SĂ©ralini, PhD, at the University of Caen in France. The study followed 200 rats for two years, the life-span of the rat, but far longer than the typical 90-day feeding studies used in regulatory assessments and subsequent approval of GM crops. The rats were fed different amounts of NK603 corn developed by Monsanto to be resistant to the herbicide Roundup. In some cases, the corn had been sprayed in the field with Roundup. Other rats were given […]

(Beyond Pesticides, September 20, 2012) Raising questions about the adequacy of pesticide regulation, historically and ongoing, Consumer Reports published a new study yesterday that finds “worrisome” levels of inorganic arsenic in rice products. Arsenic is a known human carcinogen. This new report follows its earlier one that finds high levels of arsenic in apple and grape juice. The report finds elevated arsenic levels across organic and conventional products, raising serious questions about widespread environmental and soil contamination from past and continuing arsenical pesticide use. Although organic arsenic occurs naturally in the environment, it is synthetic inorganic arsenic that poses the biggest health hazards to humans and animals. So, humans are exposed to two kinds of the carcinogen in air, water, soil, and food sources. But unlike organic arsenic, which is found naturally in the environment, inorganic arsenic is present in our food as a result of pesticide application and animal feed. Arsenic is added to chicken feed as a supplement to control intestinal parasites and promote growth. It is consequently transferred into the meat of the animals and turns up in chicken manure. Arsenic is also widely used in the treatment of utility poles and in the arsenical herbicide MSMA […]

(Beyond Pesticides, September 18, 2012) Take Action! On September 25, EPA will close its public comment period for the petition requesting the agency to suspend the bee-killing pesticide clothianidin. The U.S Environmental Protection Agency (EPA) has failed to recognize that pollinators face unique hazards from clothianidin, a neonicotinoid pesticide which is linked to disruptions in bee mobility, navigation, and feeding behavior. So far thousands of concerned beekeepers, gardeners, hobbyists and folks like you have told EPA to suspend clothianidin and protect pollinators now! Without your support, clothianidin’s effects on honey bees will continue to put beekeepers, rural economies, and our food system at risk. With one in three bites of food reliant on honey bee pollination, it’s imperative that we act now! Tell EPA to suspend the use of the bee-killer clothianidin and protect pollinators. See sample comments here. If you are having trouble submitting to the docket, click here. Background Colony Collapse Disorder (CCD) is the name given to the mysterious decline of honey bee populations around the world beginning in 2006. On average, the U.S. Department of Agriculture (USDA) reports that beekeepers have been losing over 30% of their honey bee colonies each year—but some are losing many […]

(Beyond Pesticides, September 17, 2012) Citizens in rural Oregon are concerned for their health after discovering that several major timber companies —Weyerhaeuser, Roseburg Resources, Stimson Lumber, Seneca Jones and others— have been spraying millions of pounds of herbicides on their private forestland since the 1970s. The pesticides were aerially sprayed after the area had been clear-cut of Douglas fir. This process of clear-cutting and aerial spraying for lumber production is ubiquitous on private forest land in Oregon’s $13 billion timber industry. In practice, pesticides are sprayed twice a year, usually in the fall and spring, and the spraying can last for several hours. It is unclear how many residents have been affected by the spraying, though a rough estimate based on U.S. Census data shows about 100,000 residents live near these privately owned forests. Many of these herbicides are turning up in very concerning places. Over the past year, forty one residents, including several children, have submitted their urine to be tested for pesticides, and every sample has tested positive for the chemicals 2,4-D, and atrazine. The presence of atrazine is particularly concerning because it is very mobile in the environment, and should be able to pass through the body […]

(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, September 10, 2012) Traces of pesticides in drinking water were found in eleven rural elementary schools in Oregon, according to a U.S. Department of Agriculture (USDA) study released on August 30. The study shows a disturbing variety of pesticides that when combined could have dramatic impacts on the health of the children that consume this water on a daily basis. The study found traces of several different types of pesticides in the drinking water of Dixie and Fairplay, the elementary schools that service Corvallis, Oregon. Some of the pesticides that were found in the Dixie school water include atrazine, bromacil, diuron, imidacloprid, metolachlor, norflurazon, and simazine. In the nine other schools that were found to have pesticides in their drinking water, seven different pesticides were found in the water at Applegate Elementary in Eugene, and multiple pesticides were also found in the drinking water of Ontario’s Pioneer and Cairo elementary. Children face unique hazards from pesticide exposure. They take in more pesticides relative to their body weight than adults in the food they eat and air they breathe. Their developing organ systems often make them more sensitive to toxic exposure. The body of evidence in scientific literature shows […]

(Beyond Pesticides, September 7, 2012) Yesterday, Beyond Pesticides joined with the Center for Food Safety and the Sierra Club, along with beekeepers from around the country, to file a 60-Day Notice letter with the Environmental Protection Agency (EPA) announcing the intent to jointly sue the agency for Endangered Species Act (ESA) violations. The potential lawsuit highlights EPA’s continuing failure to ensure, through consultation with the U.S. Fish and Wildlife Service, that its numerous product approvals for the neonicotinoid insecticides clothianidin and thiamethoxam are not likely to jeopardize any federally-listed threatened or endangered species. “EPA has failed to uphold the clear standards of the Endangered Species Act,” said Peter Jenkins, attorney at the Center for Food Safety. “By continuing to ignore the growing number of reports and studies demonstrating the risks of neonicotinoids to honey bees and a large number of already threatened and endangered species, the EPA is exposing these already compromised populations to potentially irreversible harm.” The Notice of Intent to Sue follows a legal petition previously filed by several environmental organizations and more than two dozen beekeepers requesting that EPA immediately suspend use of the chemical clothianidin that poses fatal harm to pollinators. While refusing to issue an […]

(Beyond Pesticides, September 4, 2012) After considering comments from growers and other stakeholders, including over 2,000 emails generated from Beyond Pesticides’ supporters on the recent proposal to reverse a decision to end the use of the organophosphate insecticide azinphos-methyl (AZM), the U.S. Environmental Protection Agency (EPA) has once again come to the conclusion that the chemical presents health risks to workers and can cause negative ecological impacts, while effective alternatives to this insecticide are available to growers. The agency has decided to maintain the initial September 30, 2012 date for cancellation of the remaining uses of AZM, on apples, blueberries, sweet and tart cherries, parsley, and pears. Though this represents a victory for farmworkers and health and environmental advocates, EPA has decided to allow growers to use only existing stocks of AZM in their possession for another year, through September 30, 2013, citing unusually bad weather conditions throughout 2012. All the required mitigation measures now reflected on AZM labeling will remain in effect during this use. Distribution or sale of AZM after September 30, 2012 remains prohibited. Due to industry pressure, the agency initially announced that it was conducting a new risk-benefit analysis (analysis of the impacts of cancellation) and […]

(Beyond Pesticides, August 28, 2012) New research reveals that bats may be at greater risk from pesticide exposure than previously suspected. When foraging at dusk, bats can be exposed to agricultural chemicals by eating insects recently sprayed with pesticides. A study from the University of Koblenz-Landau in Germany reveals that bats, due to their long life span and tendency to only have one offspring at a time, are particularly sensitive to reproductive effects from pesticides. The study, “Bats at risk? Bat activity and insecticide residue analysis of food items in an apple orchard,” published in Environmental Toxicology and Chemistry, details the health effects of bats foraging on insects in an apple orchard after it was sprayed with the insecticides fenoxycarb and chlorpyrifos. After field applications of the pesticides, scientists measured the remaining chemical residues on flies, moths and spiders for two weeks. The highest residues were recorded on leaf dwelling insects and spiders, while lower contamination was found for flying insects. Based on this data scientists calculated exposure scenarios for different bat species, each with different feeding habits, and found that those which fed off insects from the leaves of fruit trees to be most affected. Researchers indicated that current […]

(Beyond Pesticides, August 27, 2012) A report published recently in the journal Weed Science has found that a population of the common weed waterhemp in Nebraska is resistant to the herbicide 2,4-D. The news comes as the U.S. Department of Agriculture (USDA) considers approving several new crops that have been genetically engineered (GE) for resistance to the herbicide. The report presents the latest in a long line of evidence that crops engineered for herbicide resistance are only pushing the problems of weed management further down the road. Researchers from the University of Nebraska found that half of the waterhemp samples they collected from a Nebraska field, after having been treated regularly for 10 years with 2,4-D,were no longer susceptible to applications of the herbicide. The experiments performed are described by Reuters: “After 10 years of treatment with 2,4-D, waterhemp was no longer effectively controlled in a Nebraska native-grass seed production field, the report said. The highest doses of 2,4-D that were used in an on-site field study were insufficient to control 50 percent of the waterhemp population. Researchers gathered waterhemp seeds from this field and performed greenhouse testing against a susceptible waterhemp variety. Twenty-eight days after treatment with the herbicide, […]

(Beyond Pesticides, August 24, 2012) U.S. Representative Edward Markey, (D-MA) has sent a letter to the U.S. Environmental Protection Agency (EPA) urging it to investigate a possible link between the use of common pesticides and reductions in honey bee populations. The letter comes as EPA is accepting public comments on a legal petition filed by beekeepers and environmental groups seeking to suspend the use of the neonicotinoid pesticide clothianidin, which has been linked to serious pollinator health concerns. In his letter to the EPA, Rep. Markey asks the agency to respond to questions, including: ӢHas the EPA investigated the impacts of the class of pesticides on honey bees and other pollinators? ӢWhat steps has EPA taken, and what more can the agency do, to limit or restrict the use of these pesticides and reduce the impact on bee populations? ӢWhat steps is the EPA taking to ensure there is sufficient scientific evidence to make informed decisions about the impacts of neonicotinoids on bees and other pollinators? Bee pollination contributes an estimated $15 billion to the agricultural economy. Yet, recent research has found that certain members of a group of related pesticides, known as neonicotinoids, may be jeopardizing bee populations and […]

(Beyond Pesticides, August 23, 2012) Two commonly used nanoparticles have a significant impact on the growth and yield of food crops, according to a team of scientists led by University of California Santa Barbara’s Bren School of Environmental Science and Management. The study’s conclusions echo similar research findings that show human and environmental risks from nanoparticles are not fully understood, and conclude that a precautionary approach should be used until their fate and toxicity is better understood. The nanoparticles tested in the PNAS study, “Soybean susceptibility to manufactured nanomaterials with evidence for food quality and soil fertility interruption,” include zinc oxide, found in everyday products such as sunscreen, lotions, and cosmetics, and cerium oxide, used in diesel fuels to increase fuel combustion. Zinc oxide nanoparticles enter agricultural fields through the application of biosolid (sewage sludge) fertilizers, which are composed of dried microbes previously used to process wastewater in treatment plants. Researchers discovered that soybean plants grown in soil containing zinc oxide particles bioaccumulate zinc, taking up the metal and distributing it throughout edible plant tissue. This caused a decrease in the food quality of the soybeans, and researchers indicate that it is uncertain whether the zinc that accumulates in the […]

(Beyond Pesticides, August 17, 2012) Part of an increasing trend, health care and cosmetics giant Johnson and Johnson has announced that it will soon begin phasing out a number of potentially dangerous chemicals from its personal care brands, including the antibacterial triclosan. Beyond Pesticides and other groups, which have petitioned the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA) to remove triclosan from a vast array of consumer products, have urged companies like Johnson and Johnson to take action on the pesticide in the face of inadequate regulation to protect human health and the environment. Along with other chemicals such as formaldehyde and 1,4 dioxane, the company cites consumer concern over the safety of triclosan as among its reasons for the alteration in its products. While the company downplayed any need for concern over the safety of triclosan, it also hinted that it was uncomfortable with growing body of science linking triclosan to a number of health concerns. The phase out is scheduled to be complete by the end of 2015. On a website the company developed specifically regarding the chemical phase out, it stated, in part, “In recent years, some questions have been raised […]
