(Beyond Pesticides, August 3, 2010) A new study shows that due to a flaw in standard risk assessments, which consider toxic effects at fixed exposure times, the risks posed by the neonicotinoid pesticides imidacloprid and thiacloprid are likely to be underestimated. The authors believe that minute quantities of imidicloprid may be playing a much larger role in killing bees over extended periods of time than previously thought. The study, “The significance of the Druckrey—Küpfmüller equation for risk assessment””The toxicity of neonicotinoid insecticides to arthropods is reinforced by exposure time,” was published online July 23, 2010 in the journal Toxicology. The authors believe that standard risk assessment calculations underestimate toxicity because they do not accurately account for the interplay of time and level of exposure. According the study: The essence of the Druckrey—Küpfmüller equation states that the total dose required to produce the same effect decreases with decreasing exposure levels, even though the exposure times required to produce the same effect increase with decreasing exposure levels. Druckrey and Küpfmüller inferred that if both receptor binding and the effect are irreversible, exposure time would reinforce the effect. The Druckrey—Küpfmüller equation explains why toxicity may occur after prolonged exposure to very low toxicant […]

(Beyond Pesticides, Aug 2, 2010) A new report conducted by an Ann Arbor, Michigan based coalition of health and environmental groups estimates that children’s exposure to toxic chemicals, including pesticides, cost Michigan billions of dollars each year. The study examines the costs associated with four environmentally related childhood diseases: lead poisoning, asthma, pediatric cancer, and neurodevelopmental disorders. Treating these four disorders costs the state of Michigan an average of $5.85 billion annually. The study, “The Price of Pollution: Cost Estimates of Environment-Related Childhood Disease in Michigan” was released in time for the US House Energy and Commerce Committee hearings on the Toxic Chemicals Safety Act of 2010, an overhaul of the 1976 Toxic Substances Control Act (TSCA). Using conservative estimates researchers consider direct costs such as medical treatment, as well as less direct costs such as parent wage losses. The study also notes the substantial emotional costs to families dealing with these potentially life threatening or debilitating conditions which cannot be quantified. Lead poisoning is found to be the most costly of the diseases studied, costing on average $4.85 billion annually, followed by childhood asthma, pediatric cancer, and neurodevelopmental disorders. These four disorders alone cost the state of Michigan 1.5% […]

(Beyond Pesticides, July 29, 2010) A set of mandatory rules intended to reduce pesticide use in public and private schools in Indiana is pending approval after voluntary implementation guidelines failed. The Indiana Pesticides Board submitted a draft proposal in June outlining rules to minimize pesticide exposure to students. These measures include banning the use of pesticides when students are present, keeping pesticides locked in storage areas where students do not have access, providing advance notice of pesticide applications, and using pesticides with the lowest hazards to children. Although Beyond Pesticides recommend the additional step of developing a defined Integrated Pest Management (IPM) program, these tactics represent a good first step towards pesticide reduction in schools. The Indiana School Board Association developed a set of voluntary pesticide guidelines in 2001, but while rates of adoption increased, the Indiana state chemist’s office found that some schools were not implementing those policies, or had not adopted pesticide guidelines. It is important that schools adopt a comprehensive pesticide policy because children are especially vulnerable to the health hazards associated with pesticide exposure due to their small size, greater intake of air and food relative to body weight, and developing organ systems. Several pesticides, including […]

(Beyond Pesticides, July 26, 2010) Researchers at the Center for Children’s Environmental Health Research, UC Berkeley School of Public Health has found that the majority of child daycare centers surveyed do not understand the term Integrative Pest Management (IPM), and many spray pesticides without notifying parents or posting signs. Specifically, the survey found that over 90% of participating child care centers in the state of California have at least one pest problem, yet only 25% understand what IPM means. When using pesticides, 24% of survey participants do not notify parents and 35% do not post any warning signs. The survey was conducted for the California Department of Pesticide Regulation (DPR), which is required under the California Healthy Schools Act to collect data on pest management in child care centers. Children are especially vulnerable to pesticides due to their developing organ system. Because they eat more and respire more than adults relative to body size, and they often put things in their mouths, they are exposed to more pesticides than adults. Research shows that even low levels of pesticide exposure can affect a child’s neurological, respiratory, immune, and endocrine system. The California Healthy Schools Act requires schools as well as private […]

(Beyond Pesticides, July 21, 2010) Alaska’s Supreme Court halted plans to use glyphosate to kill weeds along track owned by the Alaska Railroad, which is believed to be the only herbicide-free stretch of rail in the country. This decision is in response to an emergency petition filed by Alaska Community Action on Toxics (ACAT) and others against the Alaska Department of Environmental Conservation and the Alaska Railroad Corporation (ARC) who requested the use of glyphosate for weed control. On June 2, 2010, ACAT joined with other community groups in challenging a permit that would allow the Alaska Railroad to spray toxic herbicides along the railbelt from Seward to Indian for the first time in 26 years. On July 14, 2010, the court ordered a temporary temporary restraining order and prelminary injunction for the planned spray program, in response to an emergency petition (and memorandum of points and authorities) filed by Alaska Community Action on Toxics, Alaska Center for the Environment, Alaska Survival, Cook InletKeeper and the Native Village of Eklutna. The Alaska Railroad Corporation requested permission to use the herbicide glyphosate, the active ingredient in Roundup and Agri-Dex, along a 90 mile stretch of its track between Seward and Indian. […]

(Beyond Pesticides, July 20, 2010) Washington state has denied approval of the highly toxic fumigant-based pesticide methyl iodide, and environmentalists hope other regulators follow its lead. Citing unreasonable adverse effects on human health and the environment, the Washington Department of Agriculture requested that Arysta LifeScience withdraw its application for the registration of methyl iodide on July 15, 2010. Beyond Pesticides encourages its California members and allies to contact the Governor’s office and ask that California, which is expected to make its final decision on the pesticide this month, follow Washington’s lead. All are encouraged to contact the U.S. Environmental Protection Agency (EPA) and ask that it reevaluate its decision to register methyl iodide. Find instructions for contacting the governor and EPA below. In a letter to Arysta LifeScience, Erik Johansen, Special Pesticide Registration Program Coordinator for the Washington Department of Agriculture stated, “WSDA is concerned that the proposed use of Midas products labeled in Washington could cause unreasonable adverse effects on human health and the environment.” Specific concerns stated in the letter include: potential for groundwater contamination; lack of data related to the pesticide’s ability to damage brain development; and cancer risk. Methyl iodide is promoted by the pesticide industry […]

(Beyond Pesticides, July 16, 2010) Under pressure from the grassroots group Alaska Community Action on Toxics (ACAT), the city of Anchorage canceled plans to spray the herbicides 2,4-D and dicamba on the Town Square Park citing concerns over the safety of children playing in the park. ACAT members attended the Anchorage Assembly public meeting with an NBC TV affiliate and discussed their reservations over spraying Town Square Park, a popular gathering place for families, workers eating their lunches, and tourists. Soon after, the mayor announced the spraying would be canceled, and that the city would remove dandelions by hand. Environmentalists called the decision a victory for the health of Anchorage residents and the environment. 2,4-D is associated with a host of adverse human impacts, such as non-Hodgkin’s lymphoma, endocrine disruption, reproductive and developmental effects, as well as water contamination and toxicity to aquatic organisms. It is one of the most widely used herbicide for the control of broadleaf weeds in commercial agriculture and residential landscapes in the U.S. About 46 million pounds of 2,4-D are used annually, with 16 million pounds used in non-agricultural settings, including parks, playing fields, and residential lawns. Its health risks prompted a Special Review in […]

(Beyond Pesticides, July 2, 2010) A study by researchers from Washington State University (WSU) and the University of Georgia suggests that a balanced mix of insects and fungi in organic fields provides for both better pest control and larger plants than in conventional agriculture. The study, which was funded by the U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA) and published in the July 1 edition of the journal Nature, shows that organic farming practices lead to many equally-common beneficial species, and that this reduces pest problems. “It’s always been a mystery how organic farmers get high yields without using synthetic insecticides,” says co-author Bill Snyder, Ph.D., associate professor of entomology at WSU. “Our study suggests that biodiversity conservation may be a key to their success.” The study involved 42 potato plots enclosed in fine mesh on the Pullman campus of WSU. The researchers planted both potato plants and Colorado potato beetles (a very problematic pest of the potato) in each of the plots, adding varying numbers of beneficial insects, fungi and nematodes, microscopic soil-dwelling worms that attack beetles’ eggs and larvae. Crops placed in the organic test plots with a more balanced insect population grew […]

(Beyond Pesticides, July 1, 2010) A recent study by Seong Park, Ph.D., published in the Agronomy Journal, demonstrates that manure generates higher economic returns than anhydrous ammonia, a synthetic fertilizer. Dr. Park, a research economist with Texas AgriLife Extension Service found no significant difference in yield between organic and chemical nutrient sources. The long-term experiment conducted in the Oklahoma Panhandle compares the use of pig and beef manure to anhydrous ammonia in irrigated corn fields. The region has seen rapid growth of animal population and density. The use of animal manure for fertilizer not only reduces or eliminates the need for synthetic fertilizers, it also significantly reduces waste management costs. Dr. Park found anhydrous ammonia to be the most costly source of nitrogen, due to purchase price, which is not normally required when using beef or swine manure. Swine effluent had the lowest application costs since it can be applied through existing irrigation equipment. The only additional cost would be equipment to pump effluent from the lagoon where it is stored to the center pivot. Beef manure and anhydrous ammonia require application machinery. Beef manure is however a more economical choice if it is being transported to crops on another […]

(Beyond Pesticides, June 28, 2010) A new report documents high levels of pesticide drift in the California community of Sisquoc. Poison Gases in the Field: Pesticides put California families in danger, released by Pesticide Action Network North America and local community members, presents results of community air monitoring for fumigant pesticides in the central coast area of California, in Santa Barbara County. Using a simple monitoring device called the Drift Catcher, community members measured levels of a fumigant pesticide above the California Department of Pesticide Regulation’s (DPR) “level of concern” — even when all application rules were followed and no equipment failure occurred. “While we were monitoring the air, there were no violations of the County’s permit – and yet we found we were still breathing chloropicrin at high levels,” says Deby DeWeese, one of the community members who collected air samples. “Clearly the rules and regulations do not protect our families.” The Sisquoc monitoring, conducted during and after a soil fumigation in April 2008, found the pesticide chloropicrin in about half of the 57 air samples collected. Two samples had chloropicrin levels higher than DPR’s 24-hour level of concern for children, and the 19-day average level at one sampling […]

(Beyond Pesticide, June 11, 2010) The Environmental Protection Agency (EPA) has refused the state of Ohio’s request for an emergency exemption to use the restricted pesticide propoxur in residential settings for control of bed bugs, stating that the chemical “presents unreasonable risk.” Propoxur is a highly toxic, broad spectrum insecticide. All indoor residential uses of this known neurotoxic chemical and possible carcinogen were voluntarily canceled in 2007. The Ohio Department of Agriculture, deeming the increases in bed bug infestations an emergency, requested an exemption to use propoxur in residential areas and in May the Ohio Senate’s Environment and Natural Resources Committee adopted a unanimous resolution urging the EPA to grant it. Beyond Pesticides, with coalition of environmental and public health groups, opposed the request and asked EPA to deny the exemption, citing the serious public health threat associated with the chemical, as well as the availability of alternatives. EPA determined “the requested use presents an unacceptable risk,” according to Administrator Lisa Jackson, in a letter to Ohio Governor Ted Strickland dated June 2, 2010. “Although EPA recognizes the severe and urgent challenges that Ohio is facing from bed bugs, the results of the risk assessment do not support the necessary […]

(Beyond Pesticides, June 9, 2010) Residents of New York now have new assistance in maintaining beautiful, green lawns, plants and trees without the use of toxic chemicals. The New York Department of Environmental Conservation (DEC) has initiated the ”˜Be Green Organic Yard NY” program, where participating ”˜Be Green’ businesses agree to avoid synthetic pesticides and other materials prohibited by the organic ”˜Be Green’ standard. ”˜Be Green’ landscape services utilize an organic approach focusing on preventing problems before they occur, and building a sustainable landscape that is healthy for all -plants, wildlife, pets, and people. Services can range from a simple regimen of weeding, mulching and pruning, to all aspects of yard care, including plant selection and tree and lawn installation and maintenance. DEC expects that, by the fall of 2010, yard care businesses will be able to begin taking the training required to participate in ”˜Be Green’. ”˜Be Green’ businesses sign an agreement with DEC for the right to use the ”˜Be Green’ service mark (logo). In return, businesses agree that, when they provide ”˜Be Green’ services, they will avoid the synthetic pesticides and other materials prohibited by the organic standards in the agreement. “Demand for all types of organic […]

(Beyond Pesticides, June 3, 2010) City lawmakers in Albany, New York want to strengthen an 11-year-old ban on the use of some pesticides on city land after the revelation last week that one such banned chemical was sprayed near a local playground earlier this month. Albany’s Parks and Recreation Commissioner John D’Antonio said last Friday he was unaware of the ban, passed by the council in 1998, until he began researching a recent citizen complaint. The city is now rethinking its use of pesticides and exploring why the ban on city use of pesticides dubbed most toxic by the federal government was not more widely known. The law also required departments using less toxic pesticides to annually report plans to phase them out to the Common Council. TruGreen, a city contractor, used Trupower 3 Selective Herbicide, which is a mixture of 2,4-D, mecoprop-p and dicamba, and is listed in Toxicity Category 1 (most toxic) by the Environmental Protection Agency (EPA) — causing potentially irreversible eye damage, but is also toxic if ingested and can be irritating to the skin. The herbicide has been banned from city land, except in rare circumstances, since 1999. Under the same ordinance, all city agencies […]

(Beyond Pesticides, May 17, 2010) The City of Evanston in Cook County, Illinois has passed a resolution to reduce pesticide use on City-owned and leased property (buildings and grounds) when the City Council unanimously adopted the “Sustainable Pest Control and Pesticide Reduction Policy” on April 26, 2010. The policy requires City employees, agents and contractors to follow natural lawn care and “least-toxic Integrated Pest Management” (IPM) and prohibits high hazards pesticides. It shouldn’t be too difficult for the City, as according to Evanston’s website, the City “has been applying minimal to no pesticides or insecticides in its municipal parks and on City owned properties since the early 1990s.” IPM is described in the policy as, “A pest management technique that gives preference to the safest pest control methods and uses conventional chemical pesticides only when no other feasible alternative exists. It addresses the underlying causes of pest problems, and seeks to find effective long-term solutions that emphasize prevention.” The City will hold a training session at least once every two years for managers and staff responsible for pest management on City property. All contractors engaged in pest management on City property are also required to attend the trainings or must […]

(Beyond Pesticides, May 12, 2010) Disturbed to learn that an advisory committee in his community in Boulder, Colorado had approved two new herbicides for use on city parks, a 9-year-old environmental activist organized a group of some two dozen children to protest the potential use of the herbicides in front of the Boulder County Courthouse last Friday. Xiuhtezcatl Roske-Martinez is a third grader who loves playing kickball and baseball in Boulder city parks. But then he heard that the advisory committee had approved two new herbicides for use on city parks. “I didn’t think it was right,” he said. “The children of this generation should be able to grow up without worrying about the air they’re breathing or the grass they’re playing on.” The Integrated Pest Management Subcommittee – made up of representatives of three city boards – recommended that Boulder add the herbicides, Tenacity and Barricade, to the list of allowed turf treatments. Xiuhtezcatl organized a group of some two dozen children to protest the potential use of the herbicides. They gathered Friday in front of the Boulder County Courthouse on the Pearl Street Mall waving hand-lettered signs that read “Let us play in clean parks,” “We love dandelions” […]

(Beyond Pesticides, May 10, 2010) The environmentally friendly ladybug is alive and well in Ocean Township, New Jersey, thanks to a newly adopted Township resolution that declares parks, playgrounds, and fields as “Pesticide Free Zones;” requires Township property to be managed with Integrated Pest Management (IPM), a program that manages and prevents pests using environmental information, with a focus on non-chemical pest management methods and tools (sanitation, mechanical, biological and, as a last resort, “least toxic” chemicals) that are least likely to impact human health or the environment. The Township’s goal is to eliminate the use of pesticides, while encouraging citizens to do the same. According to Ray Pogwist, Chair of the Ocean Township Environmental Commission, the IPM policy for the township identifies key sensitive areas like the village parks to be managed without harmful chemical pesticides. These areas will be posted with a sign indicating that chemical pesticides have not been applied to the site. “Ocean Township’s action reinforces their commitment to protecting parks and open spaces and reducing its pesticide use,” said Jane Nogaki, program coordinator for NJ Environmental Federation (NJEF). “Since IPM is now the law on all New Jersey school grounds, it makes perfect sense to […]

(Beyond Pesticides, May 4, 2010) On April 30, 2010, despite significant cancer and reproductive health risk, especially to farmworkers and people living near agricultural fields, the California Department of Pesticide Regulation (DPR) proposed the use of a new and highly toxic pesticide, methyl iodide, for widespread agricultural use in California. The U.S. Environmental Protection Agency (EPA) registered methyl iodide in 2007 as a replacement for the ozone-depleting pesticide, methyl bromide. Environmental and public health advocates believe that blocking methyl iodide registration in California will prevent its use elsewhere, since the state will account for the vast majority usage and profitability nationwide. Public comments may be sent to [email protected]. If registered, methyl iodide will be used primarily to fumigate and sterilize the California’s strawberry fields, although the pesticide will also be used in nurseries and nut tree production. DPR’s proposal does not require neighbor notification before use of this extremely toxic chemical. As evidenced by California’s thriving organic industry, alternatives to fumigants exist and are in use in California. In a hearing on February 8, 2010, before the California Senate Committee on Food and Agriculture, two panels of California growers and researchers discussed a number of safe and effective alternatives to […]

(Beyond Pesticides, April 29, 2010) Pest control officials in Wyoming are prepared to spray swaths of U.S. Bureau of Land Management (BLM) property with insecticide if the state experiences a grasshopper outbreak this summer as predicted by officials. Based on adult grasshopper surveys conducted by the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service(APHIS) unit in fall 2009, APHIS is expecting that the 2010 summer season of grasshopper infestations will be significantly higher than past seasons. It is estimated that 6.7 percent or 1.2 million acres of the 18 million acres of lands in Wyoming administered by the BLM are currently threatened by a predicted infestation of grasshoppers. Pest control officials consider outbreak levels to be about 15 grasshoppers per square yard – enough to cause economic problems. Such an infestation, according to BLM, would result in substantial loss of vegetation and ground cover that is vital to providing food and habitat to wildlife and livestock populations and maintaining properly functioning ecosystems. While the insects are native to Wyoming, outbreaks of certain pest species can be problematic because of their voracious appetites for grass. In discussions with APHIS and local county weed and pest districts, the BLM […]

(Beyond Pesticides, April 20, 2010) Communities from six states filed a lawsuit last month in the U.S. District Court for the Southern District of Illinois against Swiss chemical giant Syngenta AG and its American counterpart Syngenta Crop Protection, Inc., the makers of Atrazine. The 16 municipalities in the states of Kansas, Illinois, Indiana, Ohio, Missouri, and Iowa want Syngenta to pay for the expensive carbon filters needed to remove atrazine from their drinking water supply. The United States’ largest private water utility, American Water Company, has also joined the suit, representing 28 additional communities. Atrazine is used to control broad leaf weeds and annual grasses in crops, golf courses, and even residential lawns. It is used extensively for broad leaf weed control in corn. The herbicide does not cling to soil particles, but washes into surface water or leaches into groundwater, and then finds its way into municipal drinking water. It has been linked to a myriad of health problems in humans including disruption of hormone activity, birth defects, and cancer. Atrazine is also a major threat to wildlife. It harms the immune, hormone, and reproductive systems of aquatic animals. Fish and amphibians exposed to atrazine can exhibit hermaphrodism. Male […]

(Beyond Pesticides, April 19, 2010) Mississippi Governor Haley Barbour last week signed a childhood asthma management and prevention bill into law that includes provisions requiring all public school districts to implement an Integrated Pest Management (IPM) program and prohibiting the use of hazardous substances such as cleaning products and pesticides. Although the bill reads as though it will do a lot for children with asthma, with regard to the actual eliminatiion or significant reduction of toxic pesticide use at schools, the bill is weakly worded and will need strong regulations to be meaningful in protecting children from pesticide-asthma triggers. Specifically, this new law, effective July 1, 2010, requires schools to allow students to self-administer asthma and anaphylaxis medication; recommends students with asthma to have an Asthma Action Plan on file at the school; provides training for teachers, nurses, and all other school staff on asthma; requires buses to minimize idling time; requires local school health councils to adopt and support the implementation of a local school wellness policy that includes minimizing children’s exposure to pollutants that can aggravate asthma and prohibits the use of hazardous substances such as cleaning products and pesticides in and around school buildings during the hours […]

(Beyond Pesticides, April 13, 2010) While the number of Minnesota school districts purchasing fresh food from local farms has more than doubled in the last 15 months, according to a survey released last week by the Minnesota School Nutrition Association (MSNA) and the Institute for Agriculture and Trade Policy (IATP), there is no mention of organically produced food as a priority to protect children, local health or the local environment from the pollution and contamination caused by pesticide use. Communities, such as Olympia, Washington have turned to local organic food in their school lunch program. According to the Rodale Institute, “[W]hile it’s true that food produced locally generally has a smaller carbon footprint than food transported across the country (or from another continent), the carbon emitted by transporting food is smaller than that released by growing it with chemical means. In fact, PepsiCo recently documented that, for its Tropicana orange juice, transporting the product accounted for only 22% of its carbon footprint.” Rodale suggests local organic food as the gold standard because it eliminates petroleum-based fertilizers and reduces fossil fuel use in the farming operation. Rodale suggests the following priority for food purchasing: 1. Local certified organic food, 2. Local […]

(Beyond Pesticides, April 7, 2010) Although the city stopped using chemical pesticides in much of its public spaces nearly four decades ago, village officials expect to pass a resolution prohibiting their use on public property, including parks, fields and playgrounds. The hope is that the local law, once publicized, will have a trickle-down effect on private property owners. “If we can do it, why can’t people do it on their own lawn?” the village president, Douglas Newman, asked last week. On April 1, at Meadowland Park, village officials and local and state environmentalists unveiled a sign featuring a ladybug that will soon be posted in the village’s 10 parks, fields and playgrounds. James McGowan, of the South Orange Environmental Commission, which is credited with spearheading the village’s initiative, said inorganic pesticides and their use still pose a danger. “There is some serious effects from these things,” he said. “People have good alternatives,” such as integrated pest management, which uses biological controls, such as plants that are resistant to common pests.” The village’s program, he said, “brings together a lot of environmental initiatives.” Eric Benson, canvass director for the New Jersey Environmental Federation, said the benefit of announcing the plan right […]

(Beyond Pesticides, April 6, 2010) A new report analyzing regulations from California’s 25 top agricultural counties finds that many counties do more to protect crops than children from potentially harmful pesticide drift. The report, Pesticide Protection Zones: Keeping Kids Safe at School, finds that eleven counties have no protection zones around schools at all, while another six only limit spraying when school is in session. By contrast, the report notes that nearly 25% of the counties have larger pesticide buffer zones for crops than for schools. “It seems insane to have stringent rules protecting nuts and peaches while schoolchildren remain at risk from chemicals that can cause cancer, birth defects, and other serious health problems,” said Paul Towers, director of Pesticide Watch Education Fund and a co-author of the report. “But that’s exactly what’s happening in counties across California. It is past time for a simple, statewide rule that protects all California children from pesticide drift at school.” “Our children deserve to be protected from these cancer-causing chemicals,” said Assembly member Sandré Swanson, who has introduced AB 1721, the Health and Safety School Zones Act, to fix the problem. “The people of California have made it clear that clean air […]
