(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 […]

(Beyond Pesticides, January 3, 2008) The US Department of Agriculture (USDA) has struck an arrangement with agribusiness giant Monsanto Co. that gives farmers in four states a break on federal crop insurance premiums if they plant a majority of Monsanto-brand seed corn this spring. Farmers in Illinois, Indiana, Iowa and Minnesota need to plant 75-80% of their crops with Monsanto’s (and only Monsanto’s) GM seeds to receive the “premium rate discount”. The arrangement has raised some eyebrows, particularly among organic farm groups that argue the government agency should not be promoting corn that promotes herbicide use; the Monsanto brands are resistant to Roundup (main ingredient, glyphosate) and contain chemicals that kill insects and other plants. Monsanto’s deal is legal, according to USDA officials, who point out that such arrangements were encouraged in a 2000 crop insurance passed by Congress. The idea is to give farmers a break on their insurance premiums if they use corn seeds that are higher yield and show resistance to insects and other threats. USDA officials said they are aware of the appearance of favoritism toward one of the nation’s largest agricultural companies. “We knew it would look that way,” said Shirley Pugh, a spokeswoman for […]

(Beyond Pesticides, December 20, 2007) Responding to numerous requests from the public for more time to comment, the U.S. Fish and Wildlife Service has opened an additional 60-day public comment period on a draft mosquito management policy until February 17, 2008. The original press release on the proposal, issued on October 15, 2007, and the Federal Register Notice (72 FR 58321-58333) outlines guidance for determining the conditions under which national wildlife refuges will control mosquitoes. Notification of the public comment period was published in the Federal Register December 19, 2007. The Service received 35 comments during the original 45-day comment period, which closed on November 29, 2007. Mosquito Control Districts in several states as well as members of the public asked for more time to respond. The Service currently allows some form of mosquito control by state or local vector control agencies under Special Use Permits on approximately 40 national wildlife refuges, most of them in coastal areas. An interim Director’s Order, issued in May 2005, provided guidance for mosquito management on refuges while a permanent policy was being developed. The draft policy states that the Refuge System will allow populations of native mosquito species to exist unimpeded unless they […]

(Beyond Pesticides, November 30, 2007) Seven years ago, the introduction of genetically modified (GM) sugar beets, along with other crops like potatoes and rice, was shelved at fears that consumers would not support their use. Sugar beets, which produce about half of the United States sugar (almost all of which is used domestically), are used in foods like candy, cereal, and baking products. The failure of the GM beet’s initial introduction was based on unwillingness from companies like Hershey and Kellogg to provoke consumer protests. Now, the marketplace seems to have changed enough that such big sugar-buying companies are less hesitant to buy Monsanto’s “Roundup Ready” beet (which are tolerant of Roundup’s main ingredient, glyphosate). According to Kellogg spokeswoman Kris Charles, her company “would not have any issues” buying them because “most consumers are not concerned about biotech.” “Basically, we have not run into resistance,” said American Crystal Sugar president David Berg of the switch. “We really think that consumer attitudes have come to accept food from biotechnology.” Most other companies, including Hershey and Mars, are refusing to comment on the subject, which has kept these developments quiet until recently. Despite the corporate perception of public opinion on GM crops, […]

(Beyond Pesticides, November 7, 2007) A lawsuit was filed in federal court on Monday by fishing and environmental groups seeking to force the federal government to uphold five-year-old rules aimed to keep toxic agricultural pesticides from endangering salmon and steelhead. The lawsuit, filed in the U.S. District Court in Seattle, petitions the court to order the National Marine Fisheries Service (NMFS) to identify measures needed to protect salmon from the pesticides and to complete required consultations with the Environmental Protection Agency (EPA). The NMFS has failed to carry out these measures first ordered in 2002 by federal court. It was ordered to consult with the EPA to develop permanent methods for protecting salmon and steelhead from 54 toxic pesticides found in west coast salmon streams. Under the federal Endangered Species Act, the NMFS is required to complete such actions within 90 days. “Apparently what it takes to get this administration to do its job under [the Endangered Species Act] is to have someone there enforcing the law every step of the way,” said Joshua Osborne-Klein, an attorney for Earthjustice, the environmental public interest law firm representing the advocates. Pesticides have been detected in every major salmon stream in the Pacific […]

(Beyond Pesticides, November 5, 2007) Forty-four organizations signed on to a letter to the National Organic Standards Board (NOSB) on October 26, asking the board to protect organic aquaculture standards by prohibiting the USDA’s organic label from being placed on fish raised in open net pens or fed wild fish. Six months ago, the NOSB voted overwhelmingly to temporarily ban the labeling of any fish raised under these circumstances as organic until comments from industry and the organic community on the issue could be heard. During this time, the Aquaculture Working Group issued an Interim Report, which proposes conditions under which wild fishmeal and oil could be used as feed ingredients and open net pen fish farming would be allowed in organic aquaculture. In response to the report’s suggestions, the co-signing organizations conclude that while the farming of herbivorous finfish may be conducted within organic regulations, farming carnivorous finfish (including salmon) in open net cage systems is an inherently flawed farming practice, incompatible with organic principles. “Raising fish in this manner directly contradicts USDA Organic regulations; putting a USDA Organic label on these fish is like trying to force a round peg into a square hole,” said Center for Food […]

(Beyond Pesticides, November 2, 2007) According to figures released this week, genetically modified crops now cover 110,007 hectares of arable land across 7 European Union member states, an increase of more than 77 percent compared to last year, despite concerns from scientists and environmentalists. The figures show that the largest gains came from France, which quadrupled its cultivation, while Spain, the EU’s largest GM cultivator, saw increases of around 40 percent. Cultivation of GM crops also doubled in the Czech Republic and Germany. EuropaBio, the EU association for bioindustries, released the figures in advance of the Environmental Council meeting, which took place on October 30 to discuss proposals on GMO cultivation and import bans. “We are delighted to see that the uptake of biotech crops is growing despite the fact that only one product is available on the European market,” said Johan Vanhemelrijck, Secretary General of EuropaBio. He continued, “The cultivation of biotech plants is legally possible in all EU countries and we strongly urge policy makers in Europe to give all farmers the right to choose the products which they think are best to protect their crops and increase their competitiveness.” To date, the only type of GM crop […]

(Beyond Pesticides, October 16, 2007) Corn, genetically engineered (GE) to tolerate the pesticide Bacillus thuringiensis (Bt), has been found to harm non-target aquatic insects and disrupt the connected food web. A new study by researchers at Indiana University, funded by the National Science Foundation and published in Proceedings of the National Academies of Sciences, suggests that the crop, which has been licensed for use since 1996, poses an unforseen risk to aquatic ecosystems. According to the study, roughly 35 percent of American corn acreage is Bt corn. Pollen and other parts of the plants are travelling much farther than the fields in which they are planted, carrying Bt toxins through watersheds and being consumed by close relatives of the corn’s targeted pests. Caddisflies experience high mortality and stunted growth as a result of exposure. As researcher Todd V. Royer observed, they “are a food resource for higher organisms like amphibians and fish. And, if our goal is to have healthy, functioning ecosystems, we need to protect all the parts. Water resources are something we depend on greatly.” This effect went unnoticed for ten years because the Environmental Protection Agency (EPA), in its registration trials, tested Bt on a crustacean, rather […]

(Beyond Pesticides, August 13, 2007) Greenland sharks, which inhabit some of the least populated regions on Earth in seemingly pristine Arctic waters, contain high amounts of human-manufactured industrial waste in their bodies, including toxic pesticide byproducts. The findings are available online in Marine Pollution Bulletin (in press), entitled “Dioxins and PCBs in Greenland shark (Somniosus microcephalus) from the North-East Atlantic.” According to the team of researchers at Stockholm University, the highest measured concentration found is for the world’s most toxic dioxin, TCDD, a compound found in the herbicide Agent Orange, which the U.S. military used during the Vietnam War. The herbicide was used for other applications from 1961 to 1971. The study also names another set of discontinued chemicals, polychlorinated biphenyls, or PCBs, as the main source of the contaminants found in the Greenland sharks. PCBs were banned in the 1970s, which illustrates how persistent such compounds are in the environment and how long-living, top predator species may carry them for decades. Project leader Dr. Åke Bergman, Ph.D., an environmental chemist at Stockholm University, told Discovery News that he and his team decided to focus on Greenland sharks since their normal lifespan may exceed 100 years, based on an annual […]

(Beyond Pesticides, August 3, 2007) Maine is no longer the only state to prohibit the use of genetically altered corn. Despite concern from the organic farming community, Maine joined the rest of the nation last Friday when the Board of Pesticide Control (BPC) ruled to allow Bacillus thuringiensis (Bt) corn to be grown and sold in the state of Maine. With the aim of reducing the use of hazardous pesticides, the BPC registered Bt corn products from Dow AgroSciences, Pioneer Hi-Bred International and Monsanto to be grown for animal feed. Bt corn is genetically modified to produce its own pesticide, a naturally occurring toxin that protects against a combination of insects. Organic growers caution that overuse of the crop will lead to insect resistance to the Bt toxin, which is widely sprayed on organic crops. “I think it might very well be a short-term solution and farmers will be forced to use more pesticides in the future,” said Board member Lee Humphreys, a market gardener. She warned that there are too many unknowns about the genetically modified corn, such as its long-term effect on the soil and in creating resistant bugs. In addition, the safety of consuming milk and beef […]

(Beyond Pesticides, August 2, 2007) According to the Associated Press (AP), a new study finds frogs in Vermont living near farms are more than twice as likely as those living elsewhere to have deformities like missing legs. Yale University ecologist David Skelly, Ph.D., told the AP he decided to look at Vermont frogs because the state has been a hot spot during the last 10 years for deformed frogs. “We went to all these wetlands and cataloged where the deformities were found, and what kind of landscapes seemed to pose higher risks, if any,” Dr. Skelly said. “The answer was, frogs growing up in proximity to agriculture were more than two times as likely to have deformities. This doesn’t say it is chemical pesticides, but you can’t credibly consider this problem of the frogs without at least evaluating whether pesticides are involved.” Richard Levey, a biologist with the Vermont Agency of Natural Resources, said two common farm chemicals, atrazine and metolachlor, had been found in trace amounts in water from wetlands where deformed frogs had been found. But he told the AP that the concentrations were far below those thought to have any effect on aquatic life. Research by Tyrone […]

(Beyond Pesticides, July 23, 2007) New research finds several species of freshwater fish have lower temperature tolerances when exposed to the widely used pesticides endosulfan and chlorpyrifos. The discovery reveals another key pesticides issue in the global warming debate. The study, “The Effects of Three Organic Chemicals on the Upper Thermal Tolerances of Four Freshwater Fishes” (Environmental Toxicology and Chemistry, July 2007), is the work of Ronald Patra of Australia’s Department of Environment and Conservation and colleagues. The study establishes the upper temperature tolerances of both unexposed and exposed silver perch, eastern rainbowfish, western carp gudgeon and rainbow trout. Exposed fish were given sublethal doses of endosulfan, chlorpyrifos or phenol. The results show exposure to endosulfan cause a decrease of temperature tolerance in silver perch by 2.8 °C, eastern rainbowfish 4.1 °C, western carp gudgeon 3.1 °C, and rainbow trout 4.8 °C. Chlorpyrifos decreases temperature tolerance in silver perch by 3.8 °C, eastern rainbowfish 2.5 °C, western carp gudgeon 4.3 °C, and rainbow trout 5.9 °C. Phenol is not shown to cause a significant decrease in tolerance. The authors conclude, “The reduction in thermal tolerance of fish in the presence of endosulfan and chlorpyrifos suggest that, not only does temperature […]

(Beyond Pesticides, July 17, 2007) A study conducted by Canadian researchers show that high concentrations of POPs, or Persistent Organic Pollutants, can be observed in humans and other air-breathing animals even though they may not accumulate in fish. This suggests that current risk assessment methodologies need to be changed for identifying potential POPs in birds and mammals. POPs are synthetic, toxic chemicals that persist in the environment, bioaccumulate in food chains and are common contaminants in fish, dairy products and other foods. These compounds are generally accepted to be hydrophobic and fat-soluble. Screening for these bioaccumulative compounds is normally conducted with laboratory tests using fish. However researchers Barry C. Kelly, and Frank Gobas, Ph.D., at Simon Fraser University in Burnaby, British Columbia report that this methodology may overlook a significant number of pollutants that pose health risks to air-breathing animals. The study entitled “Food Web—Specific Biomagnification of Persistent Organic Pollutants” (Science 2007, v317, p236) examines the biomagnification of moderately hydrophobic compounds with octanol-water partition coefficients (Kow) between 100 and 100,000 (currently, compounds with Kow greater than 100,000 are generally categorized as bioaccumulative compounds and tend to be hydrophobic and fat-soluble) and compounds with high octanol-air partition coefficients (Koa). The compounds […]

(Beyond Pesticides, July 11, 2007) According to the U.S. Department of Agriculture’s (USDA) Economic Research Service, the number of genetically engineered (GE) crop acres by U.S. farmers has skyrocketed since their introduction in 1996, despite resistance from consumers and concerns about agricultural and environmental impacts. Because the U.S. does not require GE crops to be labeled, the only way to be sure you are not consuming these products is to buy organic, which forbids the use of GE technologies. Soybeans and cotton genetically engineered with herbicide-tolerant traits have been the most widely and rapidly adopted GE crops in the U.S., followed by insecticide-incorporated cotton and corn. The chart below shows the growth of GE soybeans, cotton and corn since 1996. (HT = modified to be herbicide tolerant, Bt = modified to produce the insecticide Bt) Since 2000, use of HT soybeans has increased from 54% of acreage planted with the crop to 91% in 2007. GE corn varieties, both HT and Bt, have increased from 25% to 73%. Cotton varieties, both HT and Bt, have increased from 61% to 87%. In addition to the lack of information available on the long-term safety of GE products, Beyond Pesticides is concerned with […]

(Beyond Pesticides, July 9, 2007) New field and laboratory research reveals that organochlorine pesticides reduce the hatching rate of alligator eggs. This finding adds to previous studies demonstrating that pesticides cause endocrine disruption in alligators, resulting in poorly developed reproductive organs. American alligators, which were delisted from the endangered species list in the late 1980s, are still experiencing low hatching rates around contaminated wetlands. In Florida, many wetlands were converted or are adjacent to farmlands and some farmlands have been restored back into wetlands in efforts to improve ecosystem health. Agricultural runoff has altered the surrounding aquatic environments by depositing pesticide residuals and skewing nutrient levels. Organochlorine pesticides, such as chlordane, toxaphene and dieldrin, have been especially problematic due to their persistent nature. The link between pesticides and reproductive problems in alligators has been firmly established since the 1990s. University of Florida zoologist Louis Guillette, Ph.D., found pesticides are linked to smaller penises and abnormal egg development in exposed alligators. Florida Fish and Wildlife Conservation Commission official Allan Woodward has also observed fewer hatches around lakes with high pesticide levels. He reports the hatching rate has improved around Lake Apopka, a large lake in central Florida, during the last two […]

(Beyond Pesticides, June 29, 2007) On June 28, 2007, forty years after it received protection under the Endangered Species Act (ESA) and thirty-five years after the banning of DDT in the U.S., the bald eagle was removed from the ESA’s “threatened” list. Bald eagle populations declined dramatically in the last century, attributed mostly to the accumulation of the pesticide DDT in fish, a staple of the eagle’s diet. The pesticide gradually poisoned females, causing them to produce thinly-shelled eggs that broke easily, preventing the embryos from growing. Years of hunting, accidental poisoning and habitat loss took an additional toll. “The rescue of the bald eagle from the brink of extinction ranks among the greatest victories of American conservation.” said John Flicker, President of the National Audubon Society. “Like no other species, the bald eagle showed us all that environmental stewardship has priceless rewards. In every state, parents and grandparents can still point to the sky and share a moment of wonder as a bald eagle soars overhead.” The U.S. Fish and Wildlife Service (FWS) in 1967 listed the bald eagle as endangered, a designation that gave the bird legal protection from harmful human activities and in 1972, the U.S. Environmental […]

(Beyond Pesticides, June 26, 2007) According to the Northwest Coalition for Alternatives to Pesticides (NCAP), the federal government continues to allow toxic pesticides to poison endangered and threatened salmon and steelhead without complying with a federal court’s decision to protect these species from such poisonings. As a result, a 60-day notice of intent to sue has been issued to the National Marine Fisheries Service (NMFS), citing unreasonable delay. Despite the passage of almost five years since the first court ruling, NMFS has yet to identify a single measure needed to protect salmon and steelhead from toxic pesticides. Now, fishing and environmental groups are again asking NMFS to fulfill its responsibility to protect endangered Pacific salmon. Glen Spain of the Pacific Coast Federation of Fishermen’s Associations, a commercial fishing industry trade association that was a co-plaintiff in the original action against EPA, commented: “It just makes no sense for the very federal agency charged with recovering west coast salmon to still allow poisons in our rivers known to kill them. Inaction is no longer an option, and threatens the whole west coast salmon fishing economy.” Toxic pesticides have been found in every Northwest river and stream tested. Many rivers are contaminated […]

(Beyond Pesticides, June 22, 2007) The U.S. Senate (S.Res. 580) and the U.S. Department of Agriculture has designated June 24-30, 2007 as National Pollinator Week. This week has been designated to recognize the important work of pollinators and their role in ecosystem health. The Pollinator Partnership, sponsored by the North American Pollinator Protection Campaign (NAPPC) and their partners, has put together numerous resources and events all across the country to raise awareness and support for pollinators and pollinator-friendly practices. Pollinators include approximately 200,000 species of beneficial insects such as bees, flies, wasps, butterflies, to name a few, along with vertebrates such as bats, birds and small mammals. Pollination is the process of pollen transfer between flowering plants that leads to fertilization. Without pollination, most plants would be unable to produce fruits or seeds and many of the foods consumed would no longer be available. Pollinators are responsible for pollinating about 75 percent of all crop plants worldwide. This translates to approximately 20 billion dollars worth of food and medicinal products. Other animals and plants also rely on pollinators for food and shelter. Recent studies indicate that these important species are disappearing. Loss of habitat, diseases and the widespread use of […]
