(Beyond Pesticides, July 28, 2008) The U.S. Environmental Protection Agency (EPA) has announced a proposed decision that residues of carbofuran, a toxic pesticide that is used on a variety of crops, will no longer be allowed on food. This effectively means that carbofuran will have to be removed from the U.S. market, benefiting consumers and farmworkers, as well as birds, which are frequently poisoned by the deadly chemical. EPA has concluded that dietary, worker, and ecological risks are of concern for all uses of carbofuran. According to EPA’s website, all products containing carbofuran generally cause unreasonable adverse effects on humans and the environment and do not meet safety standards, and therefore are ineligible for reregistration. The agency says the notice, which is available now online, will be published in the Federal Register for a 60-day public comment period on July 30, 2008. “This is a huge victory for the environment. EPA is to be congratulated for taking such decisive action to eliminate the dangers posed by carbofuran,” said Dr. Michael Fry, American Bird Conservancy’s Director of Conservation Advocacy. “This decision is based on overwhelming scientific evidence and sends a clear signal to manufacturers that it doesn’t pay to fight the […]

(Beyond Pesticides, July 17, 2008) In a new study published in Environmental Health Perspectives, researchers have found an increased occurrence of intersex toads in areas with greater agricultural land cover. This points to a link between certain pesticides and endocrine disruption, a change in the hormonal balance that can have sexual and reproductive effects. Such results implicate pesticides in the decline of amphibian populations, and suggests that these chemicals are also adversely affecting humans. The study, which was conducted in south Florida, looked at cane toads, Bufo marinus, at five sites with differing land use patterns ranging from suburban to nearly completely agricultural (primarily sugarcane and vegetables). Researchers examined physical characteristics such as coloration, sexual organs, and forelimb length, as well as hormone concentrations, and found a higher rate of feminization for toads in agricultural areas. In these areas, glyphosate (the active ingredient in Round Up herbicide) and atrazine (an herbicide) use is common. Tyrone Hayes, PhD, was one of the first to document the endocrine disrupting effects of atrazine on frogs in a laboratory setting. Countering any doubts of why this work is important, Dr. Hayes said, “People often say, ”˜It is just frogs, so who cares?’ Well it […]

(Beyond Pesticides, July 9, 2008) High food prices, climate change and increasing concern over fresh water supplies are helping to fuel interest in new genetically modified (GM) technology in the European Union (EU), which has long been wary of foods derived from tinkering with the genetic make-up of plants. The European Commission has said it believes GM crops can alleviate the current crisis in food supply, although it added in June that expediency should not overrule strict scientific scrutiny of the use of GM technology. A European Commission-sponsored Eurobarometer opinion poll last month showed a slight increase in knowledge and acceptance of the technology. New consumer interests in GM seed varieties, which are likely to be more resistant to drought and able to produce reasonable yields with significantly less water, have increased. In a similar opinion poll conducted in March, the number of EU respondents saying they lacked information on GMs fell to 26 percent, compared with 40 percent in the previous, 2005 survey.  Fifty-eight percent were apprehensive about GM use and just 21 percent in favor, down from 26 percent in favor in a 2006. The European Union has not approved any GM crops for a decade and the […]

(Beyond Pesticides, June 10, 2008) According to scientists at Simon Fraser University in British Columbia, Canada, real-world pesticide combinations, such as those found in Canada’s Nicomekl River, may contribute to latest decline in the region’s endangered salmon populations. The study, published in Environmental Science and Technology (ES&T), a publication of the American Chemical Society, examines the impact by simulating the river’s low-level pesticide mixture to examine its effects on fish. The study used steelhead trout, a member of the salmon family, and found that the pesticide mix can deaden the trout’s sense of smell. This could harm the fish’s ability to avoid predators, find mates, and migrate back to sea, the researchers say, and could contribute to the threatened and endangered status of salmon species. “Most laboratory studies examine the effects of a single chemical, often at high concentrations, but real-world streams contain a mixture of chemicals at very low concentrations,” Keith Tierney, Ph.D., the study’s coauthor, told ES&T. Dr. Tierney and his colleagues re-created river water in the laboratory under controlled conditions with carefully measured levels of the 10 most frequently occurring pesticides in British Columbia’s Nicomekl River. The mixture contained four major classes of pesticides, including the commonly […]

(Beyond Pesticides, June 5, 2008) While the Food and Agriculture Organization’s (FAO) High Level Conference on Food Security in Rome convenes June 3-5, 2008, some nongovernmental organizations (NGOs) are trying to shed light on the fact that as hundreds of millions of people throughout the world are hungry, agrochemical companies that make pesticides and genetically engineered seeds are making record profits. Although UN chief Ban Ki-moon has declared the summit a success with “a clear sense of resolve, shared responsibility and political commitment among member states to making the right policy choices and investing in agriculture in the years to come,” many NGOs fear that the policies will only continue in the model of the green revolution, which ushered in the widespread use of pesticides and fertilizers in farming. This model favors large agrochemical companies that manufacture pesticides and genetically engineered seeds and perpetuates the environmental and social devastation that goes hand in hand with industrial agriculture. The Food Summit in Rome follows the International Assessment of Agricultural Knowledge, Science, and Technology for Development (IAASTD) (also sponsored by the FAO) conference held in April of this year, which stressed the importance of agroecological and organic approaches to farming in order […]

(Beyond Pesticides, May 19, 2008) A 20-year study by the National Oceanic and Atmospheric Administration (NOAA) shows that environmental laws enacted in the 1970s are having a positive effect on reducing overall contaminant levels in coastal waters of the U.S. However, the report points to continuing concerns with elevated levels of metals and organic contaminants found near urban and industrial areas of the coasts. The report, “NOAA National Status and Trends Mussel Watch Program: An Assessment of Two Decades of Contaminant Monitoring in the Nation’s Coastal Zone from 1986-2005,” findings are the result of monitoring efforts that analyze 140 different chemicals in U.S. coastal and estuarine areas, including the Great Lakes.“It’s interesting to note that pesticides, such as DDT, and industrial chemicals, such as PCBs, show significant decreasing trends around the nation, but similar trends were not found for trace metals,” said Gunnar Lauenstein, manager of the NOAA Mussel Watch program. “What is of concern is that there are contaminants that continue to be problematic, including oil-related compounds from motor vehicles and shipping activities.” Significant findings from this report include the following: Decreasing trends nationally of the pesticide DDT are documented with a majority of the sites monitored along the […]

(Beyond Pesticides, May 8, 2008) New research shows that melting Antarctic glaciers are releasing once frozen stores of persistent organic chemicals, now banned in many parts of the world. Marine biologist, Heidi Geisz, a Ph.D. student at the Virginia Institute of Marine Science studying the fate and effect of organic contaminants in the Antarctic, has found that DDT concentrations in penguins has remained at the same levels as they were 30 years ago, when DDT was widely used. Arctic animals such as whales, seals and birds have had a significant decline in their DDT levels during the past decades, while the more stationary Antarctic penguins have not. The study, “Melting Glaciers: A Probable Source of DDT to the Antarctic Marine Ecosystem,” published in Environmental Science and Technology (DOI: 10.1021/es702919n), identifies the melting snow and ice as the continued source of total DDT in this southern ecosystem. The release of DDT also means that other persistent organic pollutants (POPs), including PCBs and PBDEs — industrial chemicals that have been linked to health problems in humans, are also being released. “DDT is not the only chemical that these birds are ingesting and it is certainly not the worst,” Ms. Geisz says. Ms. […]

(Beyond Pesticides, May 7, 2008) Twenty-five vineyards representing 925 acres or 56 percent of vineyard acreage in the Walla Walla Basin in Washington state, as well as the 110-acre Walla Walla Community College (WWCC), are newly certified “Salmon-Safe” for their land practices that help accelerate salmon’s recovery. The designation means that landowners go above and beyond regulations to adopt significant and specific measures that restore in-stream habitat, conserve water, protect streamside habitat and wetlands on site, reduce erosion and sedimentation, and reduce or eliminate the use of chemical pesticides.Certification is awarded only after comprehensive on-site assessments by independent inspectors based on Salmon-Safe’s rigorous standards. Salmon-Safe is a leading regional eco-label that in 11 years has certified more than 60,000 acres of farm and urban lands in Oregon and Washington, including one-third of Oregon’s vineyard acreage, as well as the headquarters campuses of Nike, Washington State Department of Ecology, and Kettle Foods.“The magnitude of the participation underscores the Walla Walla valley’s leadership in adopting and committing to sustainable practices that benefit people and land, and help salmon spawn and thrive,” said Dan Kent, Salmon-Safe managing director. “The certifications and assessments also mark a major expansion of Salmon-Safe east of the Cascades, […]

(Beyond Pesticides, April 14, 2008) After almost a year and a half of debate on genetically engineered (GE) crops, the Maine Legislature passed a bill last week to protect farmers from genetic trespass. According to Protect Maine Farmers, the bill prevents lawsuits for patent infringement against farmers who unintentionally end up with GE material in their crops; ensures lawsuits that do occur will be held in the state of Maine; and, directs the Department of Agriculture, Food and Rural Resources to develop and implement specific practices, or Best Management Practices, for growing GE crops. One component of the bill that was supported by many Maine farmers but failed would have required all businesses selling GE seeds in Maine to report their annual sales data to the Maine Commissioner of Agriculture. “Maine’s farmers now have some substantial assurance that if they save seed that has been contaminated by [GE] varieties, they are not at risk for a lawsuit,” states Logan Perkins, the lead organizer for Protect Maine Farmers. “Hopefully, the development of these Best Management Practices will give farmers the information they need to make good decisions about how to protect themselves, their livelihoods and their neighbors when using [GE] crops.” […]

(Beyond Pesticides, April 10, 2008) Common frogs that live in suburban areas are more likely than their rural counterparts to develop reproductive abnormalities, according to David Skelly, PhD, professor of ecology at the Yale School of Forestry and Environmental Studies. This phenomenon becomes a serious concern as the frog’s mating season begins, leaving researchers to wonder: will frogs be clear on their role in the annual ritual? Research by Dr. Skelly, soon to be published, focuses on the common green frog, Rana clamitans, within the Connecticut River Valley. A total of 233 frogs were collected from various ponds and landscapes with the river valley and among them 13 percent have abnormalities occurring in their reproductive organs. In urban areas, 18 percent of the collected frogs are intersex, and in suburban areas 21 percent. Frogs collected from agricultural areas have the lowest rate of reproductive problems with just 7 percent classified as intersex. According to Dr. Skelly, the more suburban the land cover, the more likely the abnormalities. “This is the first evidence that I think anyone has provided that agriculture is doing anything but pushing those rates higher,” remarked Dr. Skelly of the intersex phenomena. In an attempt to explain […]

(Beyond Pesticides, April 4, 2008) A study called “Long-term persistence of GM oilseed rape in the seedbank,” recently published in the journal Biology Letters, has found a genetically modified (GM) crop to persist in spite of a decade of efforts to remove it from a field. Researchers from Sweden’s Lund University and the Danish Technical University found GM oilseed rape (also known as canola) plants still growing ten years after seeds were planted. According to the study, the result contrasts previous trials: “In general, studies suggest that the majority of seeds disappear from the seedbank within two years.” The oilseed rape volunteer (rogue) plants were discovered by their resistance to the herbicide glufosinate. Researchers wrote, “This finding of volunteers, despite labour intensive control for 10 years [including intensive chemical spraying], supports previous suggestions that voulnteer oilseed rape needs to be carefully managed in order for non-GM crops to be planted after GM crops.” They added, “These results are important in relation to debating and regulating coexistence of GM and non-GM crops.” The study’s findings are consistent with previous research. A larger French study found similar survival of volunteer plants eight years after a GM trial. Swedish researcher Dr. Tina D’Hertefeldt […]

Action: Stop Congress from undermining USDA’s ability through its conservation programs to (i) curtail dangerous pesticides that exceed safety thresholds or have not been fully tested, and (ii) advance the transition to organic production and land management. Issue: USDA should retain its discretionary authority to restrict or prohibit specific classes of pesticides as a condition for participating in conservation programs. Language now on the table as a conference amendment in current Farm Bill negotiations: “The Secretary shall not prohibit [or “discriminate against” in the House-passed Farm Bill] the use of specific registered pesticides or classes of pesticides as a pre-condition for participation in programs under that [conservation] subtitle,” known as the Goodlatte pesticide amendment, named for its original sponsor, minority leader in the House Agriculture Committee Rep. Bob Goodlatte (R-VA). Threat: Conferees to the Farm Bill (Democrat and Republican Senators and Representatives from the Agriculture Committees of Congress who are negotiating the final Farm Bill language), are considering a provision included in the House Farm Bill (SEC. 11305) that would prohibit USDA from exercising its authority to restrict specific pesticides in its conservation programs. Time Frame: Conferees are debating this issue now and intend to resolve it in the next […]

(Beyond Pesticides, March 26, 2008) The sowing of gene-altered corn, called MON810, in France this spring will not be allowed until further scientific evidence on its safety is reviewed. This ruling came after growers argued that they faced serious economic harm if the ban on genetically modified crops was not immediately released before the start of the spring planting season. The French Conseil d’État last week upheld the ban instituted February 7 of this year, after concerns were raised by French President, Nicolas Sarkozy, on the heath and environmental benefits of genetically modified (GM) crops. In the ruling, presiding Judge Jean-Marie Delarue pointed out that the safety of the product needs further study. The ban would therefore be upheld until a ruling could be made on the scientific underpinning. Hearings are expected to be held in the coming months. The French Ministry of Agriculture initially imposed the ban on GM products, stating that it should remain in place until European authorities completed a review of the product. Review is required every ten years. Efforts to overturn the ban were led by the General Association of Maize Growers in France and several biotechnology companies, including Monsanto, which engineered MON810, and Pioneer, […]

(Beyond Pesticides, March 24, 2008) Scientists at the U.S. Geological Survey (USGS) announced that they have identified ten contaminants, including pesticides, in the Potomac River, which flows through downtown Washington, DC, that could be responsible for the alarming discovery of “intersex fish,” male fish producing eggs. The suspected chemicals include: atrazine, a common herbicide used in agriculture and on lawns that is already linked to sexual abnormalities in frogs; insecticides chlorpyrifos and endosulfan; the herbicide metolachlor; and two chemicals used to add fragrance to perfumes, soaps and other products, tonalide and galaxolide. To collect the samples, USGS scientists suspended a device intended to serve as a facsimile fish in the Potomac River near the Washington, DC’s Blue Plains sewage plant. The device had a plastic-coated tube, which simulated a fish’s permeable skin, and a layer of simulated fat. According to the Washington Post, the tests on this fake fat revealed a range of potentially worrisome pollutants. Most have been found in other streams around the U.S. “The types of things we’re finding are the types of things that are associated with everyday life,” David Alvarez, a U.S. Geological Survey research chemist who analyzed samples from the Potomac told the Washington […]

(Beyond Pesticides, March 20, 2008) A 2000-2005 U.S. Geological Survey (USGS) study, Pesticide Occurrence and Distribution in the Lower Clackamas River Basin, Oregon, 2000-2005, finds a variety of pesticides in river and tributary samples, along with trace-level detections of pesticides in treated drinking-water samples collected from a drinking-water treatment plant that uses the Clackamas River as a raw-water source. While the federal government is quick to point out that detections in drinking water are below existing Environmental Protection Agency (EPA) drinking-water standards and most river samples are below the agency’s aquatic life benchmarks, studies show hazardous endocrine-disrupting and immunosuppressive effects at extremely low levels — far below EPA standards. A total of 63 pesticide compounds were detected in 119 water samples collected during storm and non-storm conditions using low-level detection methods. More pesticides were detected in the tributaries than in the Clackamas River mainstem. One or more of 15 pesticides were detected in nine of 15 samples of drinking water. Environmental and public health advocates are concerned that these results add to a pattern of contamination across the country. USGS data released in 2008, shows widespread pesticide contamination in the Chesapeake Bay watershed, and a 2004 USGS report of nationwide […]

(Beyond Pesticides, March 12, 2008) BioDiversity Research Institute, a nonprofit ecological research group, released a new report that was presented March 12, 2008 to Maine’s Joint Standing Committee on Natural Resources. Entitled “Contaminant Screening in Maine Birds,” it documents over 100 harmful contaminants that were found in Maine bird eggs. Scientists collected 60 eggs, representing 23 species of birds, all of which test positive for chemical contaminants, some at levels believed to be harmful to the birds. Flame retardants (PBDEs), industrial stain and water repellants (PFCs), transformer coolants (PCBs), pesticides (OCs), and mercury are found in all 23 species of birds tested. The bird species studied live in a variety of habitats: on Maine’s ocean, salt marshes, rivers, lakes and uplands. “This is the most extensive study of its kind to date and the first time industrial stain and water repellants were discovered in Maine birds,” says report author, senior research biologist Wing Goodale with the Institute. The Common loon, Atlantic puffin, piping plover, belted kingfisher, great black-backed gull, peregrine falcon and bald eagle have the highest contaminant levels. The flame retardant deca-BDE, banned last year in Maine, is found in eight species. Overall, eagles carry the greatest contaminant load, […]

(Beyond Pesticides, February 29, 2008) The National Park Service (NPS) recently released a report documenting airborne pesticides.  The report of the  Western Airborne Contaminants Assessment Project (WACAP), with data collected from 2002 to 2007, found high concentrations of “numerous” airborne contaminants, including current and former use pesticides. Contamination is widespread throughout twenty parks throughout the western United States and Alaska, exceeding consumption levels for humans and wildlife in some areas. According to the report, the contaminants of second and third “highest concern” are “Dieldrin – an acutely toxic insecticide banned from use in the U.S. since 1987 that decreases the effectiveness of the immune system” and “DDT – an insecticide banned in the U.S. since 1972 that reduces reproductive success.” NPS also reported that Dieldrin and DDT levels exceeded the threshold for recreational fishermen in several parks, and Dieldrin levels exceeded that for subsistence fishermen in all but Olympic National Park. Fish-eating birds are also at risk in some parks. While NPS could not establish a correlation between contaminant levels and fish reproductive effects due to small sample size, two parks produced individual “intersex” fish. However, NPS stated, “This condition is commonly associated with exposure to certain contaminants (e.g., dieldrin […]

(Beyond Pesticides, February 20, 2008) Pesticides that run off agricultural land and mix in rivers and streams combine to have a greater than expected toxic effect on the salmon nervous system, according to researcher Nathaniel Scholz, PhD, a zoologist with the National Oceanic and Atmospheric Administration (NOAA) in Seattle. Dr. Scholz, who presented his findings at the symposium entitled From Kitchen Sinks to Ocean Basins: Emerging Chemical Contaminants and Human Health,  which was organized by NOAA and hosted at the American Association for the Advancement of Science (AAAS) Annual Meeting, had previously looked at the effects of individual pesticides. However, to get a more realistic idea of exposure, combinations of several pesticides were used and juvenile salmon exposed to them two at a time. The results surprised Dr. Scholz and his team. The total impact observed from combined pesticides was greater than the sum of the individual pesticides, demonstrating a synergistic effect. Some pesticides that were not deadly when tested in individual trials killed all salmon exposed to combinations. A mixture of the pesticides diazinon and malathion, exhibited the greatest synergistic effect and killed all the salmon exposed to them, even at the lowest concentrations. “It was eye opening,” Dr. […]

(Beyond Pesticides, February 15, 2008) Two studies have just been released, one by the International Service for the Acquisition of Agri-Biotech Applications (ISAAA), a promoter of genetically-engineering crops,  and the other by the Center for Food Safety (CFS) and Friends of the Earth, each with differing conclusions on the impact of genetically engineered (GE) crops on the health of our food systems. The debate is one that has existed for years, particularly as GE seeds have spread worldwide, now accounting for 280 million acres of cropland in 23 countries. Reports have historically provided significant documentation of herbicide-resistant weeds developing as a result of heavy reliance on the chemicals crops are bred to tolerate. Insect resistance has also been recently discovered. Legislators have recognized the need to protect farmers from GE contamination and resulting lawsuits from seed developer Monsanto. Concerns over a litany of health and environmental risks from GE crops continue. The timing of these two studies highlights the disparity between how the GE industry represents its product and how public interest groups evaluate the effects and risks they see to farmers and consumers alike. The ISAAA study, entitled Global Status of Commercialized Biotech/GM Crops: 2007, celebrates the first twelve […]

(Beyond Pesticides, February 14, 2008) Researchers have found what they are calling the first insect resistance in the field to genetically engineered plants that are modified to produce an insecticide called Bacillus thuringiensis, or Bt. The University of Arizona (UA) researchers, who have previously received research support from Monsanto and Cotton, Inc., are supportive of bioengineered crops and dismiss the findings of resistance, given that they are only in cotton and no other crops. The report, “Insect resistance to Bt crops: evidence versus theory,” is due out in the February issue of Nature. Concern about resistance has raised fears in the organic community that Bt, derived from natural soil bacterium, would be rendered ineffective as insect resistance spreads and this natural control collapses over time.In organic systems, composted manures and cover crops replace synthetic fertilizers, innovative weeding strategies are used instead of herbicides, beneficial insects and trap crops control insect pests, and alternatives to toxic defoliants prepare plants for harvest. Bt-resistant populations of the insect bollworm, Helicoverpa zea, were found in more than a dozen crop fields in Mississippi and Arkansas between 2003 and 2006. The bollworm resistance to Bt cotton was discovered when a team of University of Arizona […]

(Beyond Pesticides, January 24, 2008) The first state bill on genetically engineered (GE) crops passed through its first committee in February, 2007, and the latest revision is scheduled for a hearing tomorrow, January 24. While AB 541 has been pared down considerably from its first and most progressive incarnation, it includes two very important measures to protect farmers whose crops are contaminated by nearby GE fields. The first provision states, “A farmer is not liable for the breach of a seed contract or for patent infringement if a product, in which the seed labeler, or patent holder or licensee, has rights, is possessed by the farmer or found on real property owned or occupied by the farmer and the presence of the product is de minimis or not intended by the farmer.” A frequent criticism of Monsanto and the company’s overwhelming market share of seed is its tendency to sue farmers who did not plant GE seed, but whose fields were contaminated by a neighbor’s GE variety. In a 2005 report by the Center for Food Safety, Executive Director Andrew Kimbrell said, “These lawsuits and settlements are nothing less than corporate extortion of American Farmers.” (See Daily News from January […]

(Beyond Pesticides, January 23, 2008) Agribusiness giants Dow AgroSciences and Monsanto have successfully persuaded the state of Minnesota to reconsider their water-quality limit for the chemical, acetochlor. Scientists representing the industry presented their own studies to the Minnesota Pollution Control Agency (MPCA) and explained that the state’s original draft limit for acetochlor was too strict. Despite three years of research conducted by the state, scientists from Dow and Monsanto presented officials at the MCPA with six published studies- one of them in Chinese- which they claimed were overlooked by the state when determining the standard for acetochlor in waterways. As a result, the MPCA has decided to allow 3.6 parts per billion of acetochlor in rivers, more than twice the concentration of the 1.7 parts per billion previously proposed. As a result, three of five streams classified as ”˜impaired’ by acetochlor, including a popular trout stream in southeastern Minnesota, can no longer be considered polluted. Some environmental advocacy groups question whether the MPCA gave favorable treatment to the pesticide makers, claiming that other research that suggest that the chemical can cause ecological damage have not been seriously considered. “It looks like there’s a double standard, that industry can come in […]
