(Beyond Pesticides, August 29, 2011) The U.S. Environmental Protection Agency (EPA) announced last Thursday that it has entered into an agreement with the California Department of Pesticide Regulation (CDPR) to resolve a civil rights complaint from 1999 which alleged that the department’s renewal of the toxic fumigant methyl bromide in 1999 discriminated against Latino school children whose schools are located near agriculture fields. Per the agreement, CDPR has agreed to expand on-going monitoring of methyl bromide air concentrations by adding a monitor at or near one of the Watsonville, CA area schools named in the original complaint. The purpose of the additional monitor is to confirm that there will be no recurrence of earlier conditions. CDPR will share the monitoring results with EPA and the public and will also increase its community outreach and education efforts to schools that are in high methyl bromide usage areas.EPA says that this is a part of a “backlog” of more than 30 unresolved complaints. The complaint was filed in 1999 under Title VI of the Civil Rights Act of 1964 , which prohibits intentional discrimination and discriminatory effects on the basis of race, color, and national origin by recipients of federal financial assistance.

(Beyond Pesticides, August 24, 2011) Scientists say the fungus that causes apple scab appears to be growing more resistant to pesticides routinely used to control the fungus, worsening the threat of outbreaks in commercial orchards. For decades, manufacturers have come up with replacements for chemical mixtures the fungus outwitted. By using a rotating lineup of fungicides from year to year, farmers usually stayed a step ahead of the scab. But the fungus now appears to be overcoming multiple fungicides at once. In a paper published this month in the journal Plant Disease, researchers described samples collected in Indiana and Michigan that are resisting all four of the most commonly used chemical treatments: dodine, kresoxim-methyl, myclobutanil, and thiophanate-methyl. “We’ve dealt with fungicide resistance over the years, but this time we’re losing three or four different classes of completely unrelated fungicides at the same time,” said Henry Ngugi, PhD, a plant pathologist with Penn State University’s Fruit Research and Extension Center. “We have to literally go back to the drawing board.” Another ominous sign: The fungus apparently hasn’t developed any new weaknesses while evolving to resist the pesticides, unlike what usually happens in nature, the study found. Anecdotal reports from orchard owners […]

(Beyond Pesticides, August 22, 2011) A US Department of Agriculture (USDA) official speaking at an agricultural conference said that the heavy use of Roundup, an herbicide manufactured by Monsanto and used heavily on “Roundup Ready” genetically engineered (GE) crops, appears to be causing harmful changes in soil and potentially hindering yields of crops that farmers are cultivating. Reuters reported that Robert Kremer, PhD, a microbiologist with the USDA’s Agricultural Research Service, told the audience at the August 12, 2011 conference sponsored by the Organization for Competitive Markets that repeated use of the herbicide glyphosate, the key ingredient in Roundup herbicide, impacts the root structure of plants, and 15 years of research indicates that the chemical could be causing fungal root disease. Dr. Kremer first warned us about his research and questioned the government’s response last year. “This could be something quite big. We might be setting up a huge problem,” Dr. Kremer told Reuters last year. “Science is not being considered in policy setting and deregulation. This research is important. We need to be vigilant.” Monsanto created “Roundup Ready” crops to withstand its Roundup herbicide (with the active ingredient glyphosate). Growing previous Roundup Ready crops such as soy, cotton, and […]

(Beyond Pesticides, August 18, 2011) A new report by the Australian government finds that agricultural pesticides are severely damaging the Great Barrier Reef; despite this fact, sugarcane growers have been allowed a six week extension to continue to use the weed killer diuron, which was intially set to be suspended for use on August 13. The Reef Water Quality Protection Plan First Report Card estimates that 28,000 kilograms (or approximately 61,730 pounds) of pesticides enter the reef, which is the world’s largest structure made up of living organisms and a World Heritage natural wonder. The findings in the report corroborate previous research on the health of the Great Barrier Reef. The sugarcane industry claims that the research is based on old data and that there have been significant changes in practices, including cutting back on the use of pesticides. Though the Australian government acknowledges these changes, those improvements have been undermined by Cyclone Yasi. The heavy flooding from Yasi, which ripped through the region earlier this year, likely flushed pollutants out into the reef. According to the industry, the suspension of the use of diuron would drive up the costs for sugarcane growers because there is no viable alternative to […]

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

(Beyond Pesticides, August, 8, 2011) In a move that highlights serious concerns regarding the pesticide registration process, DuPont has announced that it plans to issue a total recall of its new herbicide, Imprelis, following widespread evidence and complaints that the product has caused the deaths of trees around the country. After originally giving conditional approval to the new pesticide, the U.S. Environmental Protection Agency (EPA) has now stated that it is preparing to issue a “Stop Sale” order to halt any further use of the product. According to a letter posted on DuPont’s website Imprelis-Facts.com, the company is implementing a “voluntary suspension” of Imprelis sales. It intends to ask distributors to collect all Imprelis containers, even those partially used, that they have sold and return them to the company for a refund. Earlier this year, in what some said was one of the biggest disasters of its kind since the emerald ash borer killed millions of trees, Imprelis was linked to white pine and Norway spruce trees turning brown or dying all across the country. Tree damage was reported throughout the Midwest, in East Coast states and as far south as Georgia. Many landscapers in Michigan and elsewhere switched to […]

(Beyond Pesticides, August 5, 2011) The U.S. Environmental Protection Agency (EPA) and the U.S. Department of Justice (DOJ) announced last week that Dow Chemical Company (Dow) has agreed to pay a $2.5 million civil penalty to settle violations of the Clean Air Act, Clean Water Act and the Resource Conservation and Recovery Act (RCRA) at its chemical manufacturing and research complex in Midland, Michigan. In addition to paying a penalty, Dow will implement a comprehensive program to reduce emissions of volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) from leaking equipment, such as valves and pumps. These emissions —known as fugitive emissions because they are not discharged from a stack, but rather leak directly from equipment— are generally controlled through work practices, such as monitoring for and repairing leaks. The settlement requires Dow to implement enhanced work practices, including more frequent leak monitoring, better repair practices, and innovative new work practices designed to prevent leaks. In addition, the enhanced program requires Dow to replace valves with new “low emissions” valves or valve packing material, designed to significantly reduce the likelihood of future leaks of VOCs and HAPs. Past waste disposal practices, fugitive emissions, and incineration at the Midland plant […]

(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 “RoundUp Ready” 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 “super weeds,” which have evolved to survive the treatments through repeated exposure. The most common species which have evolved these traits include pigweed (palmer amaranth), mare’s 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 Mott’s 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, Mott’s Apple Juice stood out, with one sample registering 55 parts per billion of arsenic, five times higher than the Environmental Protection Agency’s (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. “This is not the first time high levels of arsenic have been found in apple juice,” said Judy Braiman, executive director of the Empire State Consumer Project. “It 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.” Two-thirds of apple juice that Americans consume ””more than 400 million gallons annually”” 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 ”˜infestation’ appears to be localized. To keep the ”˜infestation’ 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 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, “Association of selected persistent organic pollutants in the placenta with the risk of neural tube defects,” 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 20, 2011) With flavors like “tangelo orange twist,” and “sugar lemon fizz,” 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 “Spread Love, Not Germs.” 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 13, 2011) Millions of dollars’ 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 “safer” 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 EPA’s 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 “proposed action will imperil EPA’s 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.” 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 month’s 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 “Fetal 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 USDA’s 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. USDA’s 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 “plant pests.” As the New York Times explains, “Since 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 wasn’t 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 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 pesticide’s 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 Parkinson’s 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 — 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, “Maternal and fetal exposure to pesticides associated to genetically modified foods in Eastern Townships of Quebec, Canada,” 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 Agriculture’s (USDA) National Agricultural Statistics Service […]
