(Beyond Pesticides, August 4, 2011) At least 21 different species of weeds are found to be resistant to the herbicide glyphosate, commonly sold as Roundup and used across thousands of acres of âRoundUp Readyâ genetically engineered (GE) crops, according to a series of studies in the current issue of Weed Science. Palmer amaranth, one of the weeds discussed in the journal, can reduce yields of cotton by more than 50 percent if there is a density of at least 10 of these weeds per row. Fifty-two counties in the state of Georgia had infestations of glyphosate-resistant Palmer amaranth last year. Studies confirm that the weed, which also competes with soybean, corn, grain sorghum and peanut crops, is also resistant to the herbicide phrithiobac in addition to glyphosate. Over-application and over-reliance by farmers on glyphosate to solve all of their weed problems has led to the proliferation of so-called âsuper weeds,â which have evolved to survive the treatments through repeated exposure. The most common species which have evolved these traits include pigweed (palmer amaranth), mareâs tail, and ryegrass. The spread of resistance is what has led farmers to increasingly rely on more toxic alternative mixtures, including weed killers like atrazine. There […]

(Beyond Pesticides, August 2, 2011) Under pressure from lab results showing arsenic in apple juice, the U.S. Food and Drug Administration (FDA) and New York state officials inspected a Williamson, NY Mottâs apple products plant for the toxic metal on July 26, 2011. While the lab tests commissioned by the Rochester-based Empire State Consumer Project examined several brands of apple juice and apple sauce, Mottâs Apple Juice stood out, with one sample registering 55 parts per billion of arsenic, five times higher than the Environmental Protection Agencyâs (EPA) legal limit (tolerance level) for drinking water. While no longer used in U.S. orchards, arsenic-based pesticides are still used on food crops in some countries, including China. âThis is not the first time high levels of arsenic have been found in apple juice,â said Judy Braiman, executive director of the Empire State Consumer Project. âIt is past time for the FDA to set a limit on a toxic substance like arsenic with long term health effects in the juice that kids drink.â Two-thirds of apple juice that Americans consume ââmore than 400 million gallons annuallyââ comes from China. The Empire State Consumer Project and Food & Water Watch sent a letter to […]

(Beyond Pesticides, August 1, 2011) After sighting three Japanese beetles in the vicinity of Greenback Lane and Fair Oaks Boulevard in Sacramento County, California, state officials are scheduled to spray pesticides linked to cancer, reproductive and neurological effects. On August 2, the California Department of Food and Agriculture (CDFA) is scheduled to begin ground applications of carbaryl on fruit-bearing trees, and cyfluthrin on non-fruit-bearing trees and landscape plants in attempts to stave of attacks from the voracious Japanese beetle. Japanese beetles, a threat to turf grass as well as ornamental plants such as roses and cut flowers, have been detected in the Fair Oaks area, state officials said, but the âËinfestationâ appears to be localized. To keep the âËinfestationâ from spreading countywide, Juli Jensen, Acting Agricultural Commissioner, is urging residents in the area not to move plants or plant parts. The initial treatments will be directed at adult beetles and begins August 2 with applications of carbaryl on fruit-bearing trees, and cyfluthrin on non-fruit-bearing trees and landscape plants. Two weeks later, a second treatment will be applied and augmented by a granular imidacloprid to target grubs. The applications, to occur on approximately 100 properties, will be carried out by the […]

(Beyond Pesticides, July 26, 2011) On July 25, 2011, in the case of Oluf Johnson v. Paynesville Farmers Union Cooperative Oil Company, Judge Ross of the Minnesota Court of Appeals ruled that pesticides drifting from one farm to another may constitute trespass. Organic farmers Oluf and Debra Johnson filed a civil suit alleging that the oil company sprayed a pesticide that drifted from targeted fields onto theirs, and that this prevented them from selling their crops as organic. Previously, a district court dismissed the Johnsonsâ trespass claims. The victory is important for organic growers who are frequently under threat of pesticide drift from neighboring properties. Under the federal organic standards authorized by the Organic Foods Production Act (OFPA), produce may not be labeled organic if it is contaminated with pesticide residues, as a result of off-site use, o greater than five percent of the allowable pesticide tolerance levels. Pesticide tolerances are the pesticide residue limits used in the U.S. or by countries imporing to the U.S., which are set by the federal government under the Food Quality Protection Act (FQPA). Because we live in a polluted world where pesticide residues are present, often at low levels, nearly everywhere. A very […]

(Beyond Pesticides, July 25, 2011) Exposure to certain pesticides and polycyclic aromatic hydrocarbons (PAHs) in the womb has been linked to neural tube defects, which lead to conditions such as spina bifida, according to researchers at Peking University in China. The study finds elevated levels of the organochlorine pesticides DDT, alpha-hexachlorocyclohexane (a lindane contaminant) and endosulfan, as well as PAHs in the placentas of women who had babies or aborted fetuses with such birth defects. The study, âAssociation of selected persistent organic pollutants in the placenta with the risk of neural tube defects,â was published July 8, 2011 in the online edition of the Proceedings of the National Academy of Sciences. While most organochlorine pesticides are banned or restricted, they still continue to cause problems decades after their widespread use has ended. This study reinforces the need for a more precautionary approach to regulating pesticides and industrial chemicals. Once released into the environment, many chemicals can affect health for generations, either through persistence or genetic means. PAHs are a group of over 100 different chemicals that are formed during the incomplete burning of coal, oil and gas, garbage, or other organic substances like tobacco or charbroiled meat. PAHs are usually […]

(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 âlevel of concernâ that it may disrupt hormones, and (iii) the […]

(Beyond Pesticides, July 20, 2011) With flavors like âtangelo orange twist,â and âsugar lemon fizz,â popular body care chain, Bath and Body Works, has marketed an entire line of antibacterial body care products to teens and young adults. Unfortunately, these products contain the toxic hormone disruptor and water contaminant, triclosan, which could be hazardous to teenagers whose bodies are still developing. Join Beyond Pesticides, Center for Environmental Health, and The Campaign for Safe Cosmetics in asking Bath and Body Works to stop selling triclosan products that claim to âSpread Love, Not Germs.â The Bath and Body Works antibacterial line, which includes products with names like “Tangelo Orange Twist” and “Sugar Lemon Fizz,” is marketed to teenagers using the slogan “spread love, not germs.” Although not listed on their website, this antibacterial line and others sold by the company contain triclosan as their main germ fighting ingredient. Beyond Pesticides in 2004 began voicing concern about the dangers of triclosan and in 2009 and 2010, submitted petitions to the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA), calling for the removal of triclosan from consumer products. Since then many major companies are quietly and quickly removing triclosan […]

(Beyond Pesticides, July 19, 2011) According to a U.S. Department of Agriculture (USDA) study published in the Journal of Environmental Quality, the volatilization of atrazine and metolachlor, two herbicides known to contaminate surface and ground water, consistently results in herbicide movement off the target site that exceeds nontarget field runoff, varying widely depending upon weather conditions. Linked to endocrine disruption, cancer, developmental effects, and more, increased levels of these hazardous pesticides in the air is cause for concern. When averaged over the two herbicides, loss by volatilization is about 25 times larger than movement from surface runoff, despite low vapor pressures. Agricultural Research Service (ARS) soil scientist Timothy Gish, PhD and ARS micrometeorologist John Prueger, PhD led the investigation, which looks at the field dynamics of these two herbicides commonly used in corn production. Prior to this field study, many experts believed that volatilization was not a contributing factor to water contamination because atrazine and metolachlor had a low vapor pressure. However, the monitoring of both herbicide volatilization and surface runoff at the field-scale over multiple years had never been done. So the team set up a 10-year study in an experimental field in Beltsville that is equipped with remote […]

(Beyond Pesticides, July 15, 2011) A study conducted by researchers at Michigan State University and published in the Proceedings of the National Academy of Sciences has linked the growth of industrial farming systems to increased pest pressure and higher pesticide use, highlighting the importance of biodiversity in agriculture. The researchers found that âlandscape simplificationâ in the form of conversion of natural areas to intensive monocultural crop production results in increased pest populations through the removal of natural habitat for pest predators. This in turn leads to higher rates of pesticide application by farmers in response to the increased pest pressure. As wild areas providing natural habitat to a range of wildlife and beneficial insects are destroyed and converted to conventional crop production, pest populations in the area will be robbed of their natural predators. This leads to pest population booms and to a corresponding increase in pesticides in an attempt to control them. Monocultural crop production âgrowing a single crop on hundreds and often thousands of acresâ presents a uniquely perfect breeding ground for pests as it provides acres upon acres of food and habitat with no natural checks or barriers. The study lays out the problems in this way: […]

(Beyond Pesticides, July 13, 2011) Millions of dollarsâ worth of Norway spruce and white pine trees are mysteriously turning brown and dying this summer, and the chief suspect is a new lawn chemical. The product, Imprelis, a new herbicide manufactured by DuPont, is suspected by State officials and lawn care professionals who say they think Imprelis may be attacking pines and spruces. Once again, this new incident exposes the deficiencies in the registration process for new pesticides put onto the market without a full data set. In what some say could be one of the biggest disasters of its kind since the emerald ash borer killed millions of trees, white pine and Norway spruce trees are turning brown or dying all around the country. Tree damage has been reported throughout the Midwest, in East Coast states and as far south as Georgia. Many landscapers in Michigan and elsewhere switched to Imprelis (See the MSDS here) this year to control weeds such as dandelions because it was touted as âsaferâ by DuPont for the environment than predecessors such as 2, 4-D. So many trees have died -from the East Coast west to Iowa – that the damage is projected to be […]

(Beyond Pesticides, July 12, 2011) Following the Environmental Protection Agency’s (EPA) denial of Dow AgroSciences’ request for an administrative hearing to keep sulfuryl fluoride on the market, the Natural Resources Defense Council (NRDC) sent a letter to the agency on June 29, 2011 opposing EPAâs phase-out of the toxic fumigant pesticide, which is marketed as a substitute for the outdated, ozone-depleting methyl bromide. According to its letter, the environmental group believes that the âproposed action will imperil EPAâs ability to complete the long-overdue phase-out of methyl bromide, leading to prolonged and increased depletion of the ozone layer, higher levels of ultraviolet radiation, and higher risks of cancer, cataracts, and immunological disorders.â Under pressure from a 2006 petition submitted by Fluoride Action Network (FAN), Beyond Pesticides, and Environmental Working Group (EWG), EPA announced its plan to cancel all allowable pesticide residue levels (tolerances) for sulfuryl fluoride over three years, effectively banning its use in January 2014. The agency found that when residues on food products are combined with fluoridated drinking water and toothpaste, aggregate exposure levels are too high. Beyond Pesticides has repeatedly pointed to non-toxic practices that have eliminated the need for either hazardous fumigant throughout the process. Manufactured by […]

(Beyond Pesticides, July 11, 2011) The findings of a research team suggest that the concentrations of the banned but still persistent insecticide chlordane and the widely used insecticide permethrin in cord blood may be associated with inflammatory cytokines (signaling molecules of the nervous and immune system important to intercellular communication) in the fetus. The results from the research team were significant because few studies on the developmental effects of chlordane and permethrin in humans have been performed, and they were the first to demonstrate an association between in utero exposures with changes in the immune systems of newborns. The data and findings are found in this monthâs Research Brief by the National Institute of Environmental Health Sciences (NIEHS) Superfund Research Program, which highlights the widespread aggregate pesticide exposure that individuals in the U.S. experience, focusing on a recent study on the developmental effects of chlordane and permethrin mixtures. The study looks at the relationship between cord serum concentrations of chlordane and permethrin pesticides, gestational age, size at birth and the presence of inflammatory cytokines, which are endogenous proteins secreted as signaling compounds to coordinate immune system functions. The study, entitled âFetal Exposure to Chlordane and Permethrin Mixtures in Relation to […]

(Beyond Pesticides, July 8, 2011) The U.S. Department of Agriculture (USDA) has issued a decision stating that it does not consider a new type of genetically engineered (GE) turf grass to be subject to federal regulations. In the decision announced by the USDAâs Animal & Plant Health Inspection Service (APHIS), the agency stated that it does not have the authority to regulate introduction or transportation of the GE grass seed under the provisions of the Plant Protection Act . The grass, developed by Scotts Miracle-Gro Company, has been engineered to be resistant to the herbicide glyphosate, commonly sold as Roundup. Kentucky bluegrass is a popular choice for yards and fields as well as pastures and prairies, and the GE seed is expected to be made available for consumers to plant in their home lawns, potentially making it one of the most widely planted GE crops in the country. USDAâs authority to regulate genetically modified organisms (GMOs) stems from provisions of the Plant Protection Act (relevant regulations can be found at 7 CFR 340) that are designed to ensure that GMOs do not present the potential for new âplant pests.â As the New York Times explains, âSince companies have created most […]

(Beyond Pesticides, July 6, 2011) After 27 years of fighting invasive weeds without the high-powered help of toxic chemicals, the Eugene district of the U.S. Bureau of Land Management (BLM) wants to add herbicides back into the toolkit. Eugene district BLM officials are proposing to use four herbicides to kill weeds along roadsides and in rights-of-way. The BLM stopped using herbicides in Oregon in 1984 after a court injunction in response to a lawsuit filed by the Northwest Coalition for Alternatives to Pesticides. The coalition had argued that the agency had not followed federal procedures in approving the use of herbicides on public lands, and a judge agreed. The BLM eventually wrote an environmental impact statement (EIS) on its proposal to use herbicides, but a final management plan wasnât completed until last year. The BLM said it will only be doing ground application and not spraying herbicides by helicopter or plane. The management plan permits the agency to use 17 different herbicides to control weeds but only in limited circumstances. Now individual districts, including Eugene, are developing site-specific proposals for using chemicals. Locally, four herbicides are under consideration. Glyphosate, imazapyr, triclopyr, and clopyralid are effective on a range of plants, […]

(Beyond Pesticides, July 5, 2011) Recent findings add to a growing body of evidence that persistent organic pollutants (POPs) might drive changes in the body that lead to diabetes, researchers say. A new study finds that environmental exposure to some POPs substantially increased risk of future type 2 diabetes in an elderly population. POPs are lipophilic (fat-loving) chemicals that accumulate mainly in adipose tissue and have recently been linked to type 2 diabetes. This current study, âPolychlorinated Biphenyls and Organochlorine Pesticides in Plasma Predict Development of Type 2 Diabetes in the Elderly: The Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) Study,â sought to follow up on previous findings that had linked these chemicals with type 2 diabetes and was performed to evaluate prospective associations of type 2 diabetes with selected POPs among the elderly. The team recruited a group of 725 diabetes-free elderly adults in Sweden and took blood samples to measure their levels of the pollutants. Then, the researchers followed them for the next five years. Thirty-six of the study participants were diagnosed with type 2 diabetes over that time. Nineteen POPs (14 polychlorinated biphenyl [PCB] congeners, 3 organochlorine pesticides1 brominated diphenyl ether, and 1 dioxin) were […]

(Beyond Pesticides, July 1, 2011) The U.S. Environmental Protection Agency (EPA) has granted emergency approval for the use of the neonicotinoid pesticide dinotefuran to control brown marmorated stink bugs in seven eastern states. Dinotefuran is a member of the neonicotinoid family of systemic pesticides that is known to be highly toxic to bees and associated with Colony Collapse Disorder. The states of Delaware, Maryland, New Jersey, North Carolina, Pennsylvania, Virginia, and West Virginia had previously asked EPA for emergency approval of the pesticide due to a ballooning stink bug population. The short term emergency measure became effective June 24 and will expire on October 15 of this year. Dinotefuran is already approved by EPA for use on other crops, such as grapes, cotton, and some vegetables. The emergency approval relates to the pesticideâs use on orchard crops such as apples, pears, peaches, and nectarines, for which it has not previously been allowed. Growers of those crops will now be able to apply dinotefuran from the ground twice per season. The agency will allow a total of 29,000 orchard acres to be treated, which does not include applications to the previously approved crops. Under a controversial stipulation known as a Section […]

(Beyond Pesticides, June 29, 2011) The Edison Elementary Green Team, a group of concerned parents in Denver, Colorado asked the Denver Public School Board Monday to stop the use of harmful chemicals. The group has been petitioning for almost a month now, collecting over 1,000 signatures of concerned parents and community members urging the school board to reconsider its contract with TruGreen ChemLawn which ends on July 1- tomorrow. The issue began for Nicole Baumann, one of the concerned parents who started the petition, when she heard other parents describe an incident when TruGreen sprayed the herbicide 2,4-D on school grounds while kids were playing soccer and parents were standing outside waiting to pick up their children. School officials say they do not know what happened that day; however Trena Deane, executive director of facilities management for Denver Public Schools (DPS) told Education News Colorado that they have no reason to believe TruGreen was misapplying them, and that the chemicals are typically not toxic unless they are used inappropriately. “These kids are rolling around in the grass,” Ms. Baumann told Change.org. “Our kids’ immune systems are not really developed yet. They’re susceptible. Why would we knowingly apply this where our […]

(Beyond Pesticides, June 29, 2011) The Safe Cosmetics Act of 2011 was reintroduced last week in the House of Representatives aiming to grant the U.S. Food and Drug Administration (FDA) authority to regulate personal care products, including cosmetics, to ensure they are free of harmful ingredients before they hit the shelves. Cosmetics currently go unregulated and can contain harmful ingredients like triclosan, heavy metals, formaldehyde and others which expose consumers to numerous health threats. The cosmetic and personal care product industry is self-regulated. But the Safe Cosmetics Act of 2011 will, according to U.S. Representative Ed Markey, a lead sponsor on the bill, “close a gaping hole in the federal law that allows potentially toxic chemicals to remain in the cosmetics products consumers use every day. Reps. Jan Schakowsky of Illinois, Ed Markey of Massachusetts and Tammy Baldwin of Wisconsin offered the “Safe Cosmetics Act of 2011,” which would require companies to put all of a product’s ingredients on its label. It would also require the Department of Health and Human Services to conduct random annual tests of products for harmful substances and would force FDA to produce a list of ingredients that are prohibited from being used in cosmetics.

(Beyond Pesticides, June 28, 2011) Recent studies have linked Parkinsonâs disease to pesticide exposure. In a new article published in the journal Molecular Neurodegeneration, researchers at the University of Missouri School of Medicine take some of the first steps toward understanding this link and unraveling the molecular dysfunction that occurs when proteins are exposed to environmental toxins. The study, “Oxidation of the cysteine-rich regions of parkin perturbs its E3 ligase activity and contributes to protein aggregation,” helps further explain recent NIH findings that demonstrate the link between Parkinson’s disease and two particular pesticides â rotenone and paraquat. “Fewer than 5 percent of Parkinson’s cases are attributed to genetics, but more than 95 percent of cases have unknown causes,” said Zezong Gu, MD, PhD, assistant professor of pathology and anatomical sciences. “This study provides the evidence that oxidative stress, possibly due to sustained exposure to environmental toxins, may serve as a primary cause of Parkinson’s. This helps us begin to unveil why many people, such as farmers exposed to pesticides, have an increased incidence of the disease.” Scientists previously understood that Parkinson’s is associated with oxidative stress, which is when electronically unstable atoms or molecules damage cells. The MU study yields […]

(Beyond Pesticides, June 27, 2011) A study published in the May 2011 edition of the journal Reproductive Toxicology finds pregnant women and their fetuses contaminated with pesticides and metabolites of the herbicide gluphosinate and the Cry1Ab protein of the insecticide based on the bacterium bacillus thuringiensis (Bt), both affiliated with genetically engineered (GE) food. The study, âMaternal and fetal exposure to pesticides associated to genetically modified foods in Eastern Townships of Quebec, Canada,â also identified the same chemicals, as well as glyphosate metabolites in the bodies of non-pregnant women. The study, conducted by researchers at the University of Sherbrooke Hospital Centre in Quebec, Canada, is intended to pave the way for a new field in reproductive toxicology including nutrition and utero-placental toxicities. Herbicide resistance is the most common genetically modified trait in commercial agriculture. Crops are modified to be able to withstand extremely high doses of glyphosate (Roundup Ready) and gluphosinate (LibertyLink). Current herbicide resistant crops include soy, maize (corn), canola, sugar beet, cotton, with and alfalfa. As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. The recently released 2010 Agricultural Chemical Use Report by the U.S. Department of Agricultureâs (USDA) National Agricultural Statistics Service […]

(Beyond Pesticides, June 22, 2011) Exposure to two herbicides, atrazine and 2,4-D, commonly used in lawn care and forest management will be studied by Oregon health officials after they were found in the urine of residents of the Triangle Lake area of the Coast Range west of Eugene, Oregon. The State Department of Agriculture is directing health officials who are part of the stateâs Pesticide Analytical Response Center to take the lead in studying the matter. Triangle Lake area residents and a group of activists called the Pitchfork Rebellion have been complaining for more than seven years about the possibility that herbicides being aerially sprayed on nearby private forests may be drifting onto their land. The group in the past has asked the state to investigate their concerns, staging rallies and protests, and attending meetings of government agencies, including the pesticide response board and the Oregon Board of Forestry. At an April 2011 meeting of the forestry board, when the group presented proof of chemical exposure, the state agreed to take a closer look. The board regulates logging and related practices on private timberlands in Oregon. At that meeting, Dana Barr, PhD, a research professor at Emory University’s Environmental and […]

(Beyond Pesticides, June 20, 2011) In a study published this week in the journal Pediatrics, researchers report findings that link mothersâ exposure to organochlorine pesticides during pregnancy with infantsâ sizes at birth. The trend shows that the more mothers are exposed to the pesticides during pregnancy, the higher the chances are for reduced birth weight and length of their newborns. Comprising a total of 494 women and infants in Valencia, Spain from the years 2003-2006, the study evaluates umbilical cord blood for residues of four pesticides or pesticide degradates: DDT, DDE, hexachlorobenzene (HCB), and beta-hexachlorocyclohexane. The results show that a 10-fold increase in pesticide concentrations in the blood corresponds to a reduction in birth weight of 2-4 ounces. Additional results are correlated to specific pesticides. Higher concentrations of DDT results in a reduction in head circumference of 0.26cm, which the researchers call a âsignificant decrease.â Additionally, a decrease of 0.39cm in birth length is correlated with each 10-fold increase in concentration of HCB. The researchers note several concerns related to the findings, aside from the results themselves. Since people are exposed to a wide variety of chemicals in general throughout their everyday lives, higher pesticide exposure could betray higher exposure […]
