(Beyond Pesticides, March 4, 2010) Scientists at Purdue University have found that nanosilver that is sonicated or suspended in solution is toxic and even lethal to fathead minnows, an organism that is often used to measure toxicity on aquatic life. The study is the latest research to demonstrate the need for federal regulatory agencies to regulate emerging nanotechnologies as a unique pesticide. The study, “The effects of silver nanoparticles on fathead minnow (Pimephales promelas) embryos,” led by Maria Sepúlveda, PhD and published in Ecotoxicology, describes the toxicity of two commercial silver nanoparticle products: NanoAmor and Sigma. Fathead minnows at several stages of their development were exposed to varying concentrations of either suspended or stirred nanoparticle solutions for 96 hours. When the nanosilver was allowed to settle, the solution became several times less toxic, but still caused malformations in the minnows. With or without sonication, nanosilver caused irregularities, including head hemorrhages and edema, and was ultimately lethal. “Silver nitrate is a lot more toxic than nanosilver, but when nanosilver was sonicated, or suspended, its toxicity increased tenfold,” said Dr. Sepúlveda. “There is reason to be concerned.” Using Transmission Electron Microscopy, Dr. Sepúlveda was able to detect nanosilver particles measuring 30 nanometers […]

(Beyond Pesticides, March 3, 2010) A recently published study in the Proceedings of the National Academy of Sciences finds that male frogs exposed to the herbicide atrazine can become so completely female that they can mate and lay viable eggs. This latest study adds to the growing scientific evidence which shows that atrazine, one of the most common herbicides used in the U.S., disrupts the development and behavior of aquatic animals, and negatively effects their immune, hormone, and reproductive systems. The study, “Atrazine induces complete feminization and chemical castration in male African clawed frogs (Xenopus laevis),” led by Tyrone Hayes, PhD, at the University of California, Berkeley, demonstrates the reproductive consequences of atrazine exposure in adult amphibians. Dr. Hayes and other researchers examined a group of 40 African clawed frogs, all of which carried male chromosomes. As tadpoles, the frogs were put in water with 2.5 parts per billion (ppb) of atrazine — a concentration within federal drinking water standards. Atrazine-exposed males were both demasculinized (chemically castrated) and completely feminized as adults. Exposed genetic males developed into functional females that copulated with unexposed males and produced viable eggs. The eggs produced were all male offspring since both parents contributed male […]

(Beyond Pesticides, February 18, 2010) Hundreds of dead and dying lobsters just north of the Gulf of Maine were found to have been exposed to cypermethrin, a highly toxic synthetic pyrethroid pesticide registered for agricultural and residential use that some officials think may have been illegally used in fish farming. However, the chemical, which is primarily used for indoor insect control and termites, is extremely toxic to fish and aquatic organisms and part of a family of pesticides (synthetic pyrethroids) that is increasingly showing up in water bodies at toxic levels, a cause for concern according to scientists. Area fisherman are angry and concerned, however investigators are not yet certain just how this pesticide wound up in the Bay of Fundy, which is located between the Canadian provinces of Nova Scotia and New Brunswick. The first dead lobsters were discovered last fall in Grand Manan’s Seal Cove, and only a few days later fisherman found dead lobsters in two different locations in the Bay, including about 816 kilograms of dying or dead lobsters in Deer Island’s Fairhaven Harbour. This prompted an investigation by Environment Canada that began on December 22, 2009. The department looked at samples of crab, kelp, mussels […]

(Beyond Pesticides, October 5, 2009) An analysis of more than 100 scientific studies conducted on atrazine, published in the online edition of Environmental Health Perspectives, demonstrates the toxicity of atrazine to aquatic animals. Biologists at the University of Southern Florida (USF) have found evidence that atrazine harms fish and frogs. Atrazine is disruptive to the development and behavior of aquatic animals, and negatively effects their immune, hormone, and reproductive systems, according to the studies done by USF assistant professor Jason R. Rohr and postdoctoral fellow Krista A. McCoy. Atrazine is commonly used on lawns, golf courses, and sugarcane fields in Florida, and has recently been the topic of much controversy. While atrazine typically does not kill amphibians and freshwater fish, the USF report says it did: ”¢ Reduce the size of amphibians at or near metamorphosis in 19 of 19 studies. ”¢ Make amphibians and fish more active in 12 of 14 studies but reduced behaviors used to evade predators in six of seven studies. ”¢ Alter at least one aspect of male frogs’ reproductive development in eight of 10 studies. ”¢ Reduce the functioning of animals’ immune systems and often put them at risk of infection. Atrazine, a common […]

(Beyond Pesticides, September 18, 2009) Previously documented in the Potomac River, which flows through downtown Washington, DC, the occurrence of “intersex” fish is now found to be nationwide. U.S. Geological Survey (USGS) researchers published their study, “Widespread occurrence of intersex in black basses from U.S. rivers” in the online edition of Aquatic Toxicology. USGS researchers examined 16 different species of fish across the U.S. between 1995 and 2004. The condition of intersex fish, male fish producing eggs, is most commonly found in smallmouth and largemouth bass. One third of male smallmouth bass and one fifth of the male largemouth bass are intersex. Scientists tested sites in the Apalachicola, Colorado, Columbia, Mobile, Mississippi, Pee Dee, Rio Grande, Savannah, and Yukon River basins. Research shows intersex fish in approximately one-third of all examined sites. The only site where researchers found no intersex fish is the Yukon River basin. While the study did not look for the causes for intersex fish, scientists believe endocrine disruptors, chemicals that interfere with the body’s hormonal systems, are certainly to blame. “We know that endocrine-active compounds have been associated with intersex in fish, but we lack information on which fish species are most sensitive to such compounds, […]

(Beyond Pesticides, September, 15, 2009) On September 11, 2009, the Environmental Protection Agency (EPA) announced plans to place additional limitations on the use of three organophosphate pesticides ”” chlorpyrifos, diazinon and malathion ”” to protect endangered and threatened salmon and steelhead in California, Idaho, Oregon and Washington. The announcement comes in response to a series of lawsuits brought by Pacific Coast Federation of Fishermen’s Associations (PCFFA), the Northwest Coalition for Alternatives to Pesticides, and other salmon advocates, with legal representation from Earthjustice, aimed at removing toxic pesticides from salmon spawning streams throughout the northwest. In response to the litigation, the National Marine Fisheries Service (NMFS) in November of 2008 released a “biological opinion” that set forth a plan for protecting Pacific salmon and steelhead from three toxic organophosphate pesticides. That decision came after almost a decade of legal wrangling between salmon advocates led by Earthjustice and the federal government. The biological opinion prescribed measures necessary to keep these pesticides out of water and to protect salmon populations in Washington, Oregon, California, and Idaho. The announcement from EPA moves this work forward. Although the experts at NMFS recommended prohibiting aerial applications of the three pesticides within 1,000 feet of salmon waters […]

(Beyond Pesticides, September 14, 2009) On September 9, 2009, the seven draft reports stipulated in President Obama’s Executive Order on the Chesapeake Bay were released by federal agencies. The seven drafts are: reducing pollution and meeting water quality goals, targeting conservation practices, strengthening storm water management at federal facilities, adapting to impacts of a changing climate, conserving landscapes, strengthening science for decision making, and conducting habitat and research activities to improve outcomes for living resources. President Obama signed the executive order on May 12, 2009. The seven draft reports are now available to the public. The Federal Leadership Committee will use these draft reports to create a strategy defining the actions needed to restore the Chesapeake Bay. On November 9, 2009, the strategy will be released for public comment. The public comment period will last 60 days, and a final strategy will be completed by May 12, 2010. Although the final strategy will not be released until May 2010, agencies will be taking action in several areas before the strategy is finalized. EPA Administrator Lisa P. Jackson said, “We will not just be reviewing reports for the next eight months.” She promises to “take advantage of rules that she implied […]

(Beyond Pesticides, August 26, 2009) The commonly used herbicide atrazine can spike at extremely high levels which go undetected by regular monitoring, according to new report by the Natural Resources Defense Council (NRDC), Poisoning the Well. Currently, the U.S. Environmental Protection Agency (EPA) considers an annual average atrazine level of below 3 parts per billion to be acceptable for human consumption, although studies have shown adverse health impacts below EPA’s “safe” levels. The analysis by NRDC discovered that in the 139 municipal water systems from which EPA collected data on a biweekly basis in 2003 and 2004, atrazine is found 90% of the time. Furthermore, 54 of these water systems have at least one spike above 3 parts per billion. “The data shows that EPA is unable to adequately regulate atrazine and protect the public from this hazardous herbicide in our drinking water,” said Jay Feldman, executive director of Beyond Pesticides. “With studies showing hormonal and other adverse effects at extremely low levels, any level of atrazine in our drinking water is dangerous and spikes above EPA’s 3 ppb threshold are completely unacceptable. EPA must put public health first and ban this toxic chemical.” Under the federal Safe Drinking Water […]

(Beyond Pesticides, August 21, 2009) Pesticide use around our homes are an underestimated source of water pollution – leading to more than 50 percent more water pollution than previously believed, according to scientists looking at pesticide use in residential areas in California. The polluted runoff has been linked to fish kills and loss of aquatic species diversity. The findings of a new study were reported earlier this week at the 238th National Meeting of the American Chemical Society in Washington, DC. In the study, Lorence Oki, from the Department of Environmental Horticulture at the University of California Davis, Darren Haver, with University of California Cooperative Extension, and their colleagues explain that runoff results from rainfall and watering of lawns and gardens, which winds up in municipal storm drains. The runoff washes fertilizers, pesticides and other contaminants into storm drains, and they eventually appear in rivers, lakes and other bodies of water. “Results from our sampling and monitoring study revealed high detection frequencies of pollutants such as pesticides and pathogen indicators at all sites,” Mr. Oki said of their study of eight residential areas in Sacramento and Orange Counties in California. Preliminary results of the study suggest that current models may […]

(Beyond Pesticides, August 7, 2009) A recent study published in the journal Environmental Health Perspectives has added to evidence that certain pesticides significantly increase one’s risk of developing Parkinson’s disease (PD). Researchers found that rural residents who drank private well water within 500 meters of fields sprayed with certain pesticides had an increased – up to 90 percent – risk of developing PD, and those with Parkinson’s “were more likely to have consumed private well water, and had consumed it on average 4.3 years longer.” The study evaluated more than 700 people, including carefully chosen controls, in Fresno, Kent, and Tulare counties. 17 percent reported drinking private well water between 1974 and 1999. Researchers focused on wells’ proximity to agricultural fields sprayed with pesticides, since private wells are not regulated, and many are shallow enough to be contaminated by pesticides seeping into groundwater. Researchers looked at 26 pesticides and six in particular, “selected for their potential to pollute groundwater or because they are of interest for PD, and to which at least 10% of our population were exposed.” Those are: diazinon, chlorpyrifos, propargite, paraquat, dimethoate, and methomyl. Propargite exposure was most closely correlated with incidence of PD, with a 90 […]

(Beyond Pesticides, July 31, 2009) A group of advocates and experts is warning that pesticide pollution from farm fields and households is contributing to the Chesapeake Bay’s decline, and may well be linked to declines in frogs across the region and intersex fish seen in the Potomac River. In a report released yesterday, the group calls on federal, state and local government to accelerate research into what threats pesticide contamination may pose to the bay, and to step up efforts to reduce such toxic pollution. “The thing that alarms us the most are the endocrine disruptors and the findings that have come out about intersex fish and frogs with reproductive problems,” said Robert SanGeorge, director of the Pesticides and the Chesapeake Bay Watershed Project. Endocrine disruptors are chemicals that mimic the natural hormones in humans or animals and can disrupt their growth and reproduction. The project is a partnership between the Maryland Pesticides Network and the Johns Hopkins Center for a Livable Future. The group’s warning and recommendations are the product of a two-year study, in consultation with scientists, public health experts, government officials, watermen, environmentalists, farmers and pest management industries. The report comes as federal and state governments attempt […]

(Beyond Pesticides, July 23, 2009) A new study published in the August 2009 issue of Environmental Toxicology and Chemistry found that insecticides used in highly populated agricultural areas of California’s Central Valley affect amphibians that breed in the Sierra Nevada Mountains to the east. This study adds to the increasing evidence that pesticides impact areas and wildlife species that are miles from sources of pesticide application. Researchers from the Cooperative Wildlife Research Laboratory, Southern Illinois University and U.S. Geological Survey (USGS) examined the chronic toxicity of two of the insecticides most commonly used in the Central Valley- chlorpyrifos and endosulfan, to larval Pacific treefrogs (Pseudacris regilla) and foothill yellow-legged frogs (Rana boylii), the amphibians with declining populations that live and breed in meadows surrounding the Sierra Nevada. The results are discussed in “Toxicity of Two Insecticides to California, USA, Anurans and Its Relevance to Declining Amphibian Populations.” The study used laboratory testing to examine how the insecticides affected the two frogs at environmentally realistic concentrations. During testing, tadpoles were observed at various stages of development to see how the insecticides affected their growth and health. The researchers found that endosulfan was more toxic than chlorpyrifos to both species, and tadpoles […]

(Beyond Pesticides, July 22, 2009) The Oregon Department of Agriculture (ODA) recently released statistics for statewide pesticide use in 2008, while at the same time announcing the suspension of the reporting system, which has only been collecting data since 2007. The Pesticide Use Reporting System (PURS) was suspended until 2013 by House Bill 2999, due to lack of funding. The $800,000 saved will instead be used to fund two investigator positions. Until its reinstatement, officials will be unable to collect data or pursue enforcement related to missing reports from earlier in 2009. The 2008 PURS report documents agricultural and household pesticide use, which totaled almost 20,000 pounds and 572 different active ingredients. The top five active ingredients, by pounds, were all used in agriculture: metam sodium, glyphosate, 1,3-dichloropropene, sulfuric acid, and aliphatic petroleum hydrocarbons. Agriculture totaled 77 percent of all pesticide use, with urban/general indoor and outdoor uses totaling under four percent. The total used dropped by half from 2007, due in part to improved record keeping and a decline in the use of metam sodium, a popular fumigant in potato production. In households, pesticide use may be shifting away from the most toxic products. “In 2007, everyone was just […]

On July 14, 2009, Beyond Pesticides and Food and Water Watch submitted an amended petition to the United States Food and Drug Administration (FDA) requiring that the agency ban the use of the controversial pesticide triclosan for non-medical applications on the basis that those uses violate the Federal Food, Drug and Cosmetics Act. Strong scientific evidence suggests that pervasive use of triclosan poses imminent threats to human health and the environment. “Numerous scientific studies and reports clearly indicate that in addition to its human health and environmental dangers, triclosan is not effective for many of its intended benefits and may actually be doing consumers more harm than good,” said Wenonah Hauter, executive director of Food & Water Watch. “Even worse, is that current regulations on triclosan haven’t been updated since 1994 and much of the science used by the FDA to regulate the pesticide dates back to the late 1970s and early 1980s. The agency’s inconsideration of new scientific research on triclosan represents an egregious failure to properly protect the public against this dangerous pesticide.” Regulated by both the FDA and the United States Environmental Protection Agency (EPA), triclosan is commonly found in hand soaps, toothpastes, deodorants, laundry detergents, fabric […]

(Beyond Pesticides, July 6, 2009) Last week, the U.S. Environmental Protection Agency (EPA) proposed to formally evaluate the harmful effects of 74 pesticides on 11 endangered and threatened species in the San Francisco Bay Area over the next five years, and to impose interim restrictions on use of these pesticides in and adjacent to endangered species habitats. The proposal stems from a settlement agreement with the Center for Biological Diversity, which sued EPA in 2007 for violating the Endangered Species Act by registering and allowing the use of toxic pesticides in Bay Area endangered species habitats without determining whether the chemicals jeopardize those species’ existence. “Tens of millions of pounds of toxic and poisonous chemicals, known to be deadly to endangered species and harmful to human health, including proven carcinogens and endocrine disruptors, are applied in the Bay Area each year, and many of those find their way through runoff or drift into our soil, creeks and rivers, San Francisco Bay, and sensitive wildlife habitats,” said Jeff Miller, conservation advocate with the Center. “The toxic stew of pesticides in the Bay-Delta has played a major role in the collapse of native fish populations, and pesticides are a leading cause of […]

(Beyond Pesticides, July 2, 2009) The EPA has just finished up with a round of public hearings on a proposed plan to cap a part of the Palos Verdes Superfund Site. This 17 square mile area of ocean floor off the Southern coast of California is home to one of the largest deposits of DDT in the U.S. Despite the fact that this chemical has been banned in the U.S. for almost four decades, there is an approximate 110 tons of DDT in the sediment of the Palos Verdes Shelf. Concentrations of DDT and PCBs in fish continue to pose a threat to human health and the natural environment including the discovery of highly contaminated fish. In addition, a surge of additional problems with the lingering effects of DDT have risen in recent years, particularly with its buildup in our waterways. It has currently been identified as a threat to the Columbia River, as well as to the arctic. It has also been linked to a plethora of health concerns, including breast cancer, diabetes, non Hodgkin lymphoma, and autism. Most of the contamination of the Palos Verdes Shelf is attributed to The Montrose Chemical Corporation of California. At one time […]

(Beyond Pesticides, June 23, 2009) According to a study published in the August-September 2009 issue of the journal Environmental Pollution, the presence of triclosan, a widely-used antibacterial pesticide found in products from countertops to toothpaste, was detected in the in the blood of bottlenose dolphins. The study, “Occurrence of triclosan in plasma of wild Atlantic bottlenose dolphins and in their environment,” was the first to find triclosan in the blood of a marine mammal, suggesting that contamination from sewage systems is widespread. According to a synopsis by Environmental Health News, the study examined dolphins from rivers, an estuary, a harbor and a lagoon in South Carolina and Florida. In this study, wild bottlenose dolphins were live captured from several sites within an estuary in Charleston, SC and in the Indian River Lagoon, FL in 2005. Blood samples taken from 13 animals in each area revealed triclosan in 31 and 23 percent of the animals from the two sites, respectively, at levels ranging from 0.025 to 0.27 parts per billion. These levels are similar to what has been measured in the blood of humans. When introduced to the market in 1972, triclosan was confined to hospital and health care settings. Since […]

(Beyond Pesticides, June 18, 2009) Do you ever wonder about pesticides on your food or in your drinking water, and in particular, which of those pesticides are most hazardous? On June 17, 2009, Pesticide Action Network North America (PANNA) launched its What’s On My Food database, which makes the results of government tests for pesticide residues in food available online in a searchable, easy-to-use format. The database shows what pesticides are found on each food, in what amount, and — for the first time — links those residues to the health effects associated with exposure to each of the chemicals. “This kind of public visibility around pesticides is particularly needed in the U.S., since regulators base their decisions on toxicology studies that are almost all done by industry,” explains Brian Hill, PhD, senior PANNA scientist and the primary developer of the database. “Nearly 900 million pounds of pesticides [excluding wood preservatives, chlorine and specialty biocide pesticides] are used in the U.S. every year, yet regulations depend on studies that are not peer-reviewed and are kept hidden behind the veil of ”˜confidential business information.’” Dr. Hill notes that the 900 million figure is long overdue for updating, as the most recent […]

(Beyond Pesticides, June 10, 2009) On June 4, Australia’s Queensland Government introduced legislation to prevent dangerous runoff of farm pollution, marking a major turning point for the conservation of the Great Barrier Reef. Some farmers claim it is unnecessary government interference in agricultural practices. Currently 80 percent of rivers draining to the Reef breach water quality guidelines due to farm fertilizer, pesticide and sediment runoff. The Queensland Government introduced the bill, entitled the Great Barrier Reef Protection Act, into Parliament to regulate farm practices and pesticide use. More specifically, the bill targets water pollution control at its agricultural origin. Failure to comply could trigger a $30,000 fine. Activists, while welcoming the new measure, say such legislation should have been introduced years ago. Environmental groups: WWF-Australia, Queensland Conservation, Australian Marine Conservation Society and Wildlife Queensland are united in their support for the new laws. Premier Anna Bligh says the Great Barrier Reef Protection Act will decrease sediment, nutrients and pesticides entering the reef. World Wildlife Fund (WWF) spokesman Nick Heath says the legislation will help the environment and farmers. “The Government’s just released a new estimate that there’s over $30 million worth of fertilizer and pesticide going onto the reef every […]

(Beyond Pesticides, May 27, 2009) A recent, extensive study which investigated a variety of different chemicals, including organochlorine pesticides, in animal tissues reveals that marine mammals harbor high concentrations of hazardous chemicals in their brains. The results lay the groundwork for understanding how environmental contaminants influence the central nervous system of marine mammals. The study entitled “Organohalogen contaminants and metabolites in cerebrospinal fluid and cerebellum gray matter in short-beaked common dolphins and Atlantic white-sided dolphins from the western North Atlantic” is the first of its kind to find toxic chemicals in the brains of marine mammals. The study identified several contaminants including organochlorine pesticides like DDT, polychlorinated biphenyls (PCBs) and flame retardants in the cerebrospinal fluid and cerebellum gray matter of several species of marine mammals including the short-beaked common dolphins, Atlantic white-sided dolphins and the gray seal. PCBs were found in alarmingly high concentrations. Researchers found parts per million concentrations of PCBs in the cerebrospinal fluid of a gray seal. “We found parts per million concentrations of hydroxylated PCBs in the cerebrospinal fluid of a gray seal. That is so worrisome for me. You rarely find parts per million levels of anything in the brain,” remarked researcher, Eric Montie, […]

(Beyond Pesticides, May 19, 2009) Nearly six months after federal scientists began issuing restrictions to protect salmon and steelhead in the Pacific Northwest and California, the U.S. Environmental Protection Agency (EPA) has yet to take even the first step toward implementing these protections. This delay follows almost a decade of legal wrangling in which a coalition of environmental and fishing groups, led by the non-profit public interest law firm Earthjustice, won a court order. Tell EPA to stop its foot-dragging and protect salmon and steelhead from toxic pesticides. The six pesticides that scientists have reviewed so far are some of the most dangerous chemicals used today. All six””chlorpyrifos, diazinon, malathion, carbaryl, carbofuran, and methomyl””are neurotoxic and pose serious risks to both humans and wildlife. While many of these pesticides have been phased out for residential use, they continue to expose wildlife and farmworkers through their use in agriculture. Thirty-one more chemicals will undergo review by scientists at the National Marine Fisheries Service (NMFS) in the next three years. The new restrictions require EPA to prohibit application of the six pesticides in or near salmon and steelhead habitat. They also require EPA to prohibit application when the weather may cause the […]
