EPA Imposes Pesticide Limits to Protect Salmon in Spite of Industry Refusal to Comply

(Beyond Pesticides, May 19, 2010) EPA has announced plans to place additional limitations on the use of three N-methyl carbamate pesticides — carbaryl, carbofuran and methomyl — to protect endangered and threatened salmon and steelhead in California, Idaho, Oregon and Washington, in compliance with the Endangered Species Act. The decision comes after manufacturers of the chemicals diazinon, malathion and chlorpyrifos refused to adopt the limits voluntarily. The new protections are based on recommendations by the National Marine Fisheries Service (NMFS) in their April 2009 Biological Opinion relative to use of the three pesticides to ensure no likely jeopardy to 28 threatened or endangered Pacific salmon and steelhead species. In a May 14, 2010 letter to NMFS, EPA explains how the Agency plans to achieve protection goals through the methods outlined by NMFS in the Biological Opinion or by alternative methods that EPA’s scientific analyses determined will achieve the same purpose. For example, EPA will require pesticide drift buffers adjacent to salmon and steelhead habitat but will impose different width buffers, some wider and others narrower than those recommended by NMFS, depending on factors that affect how far the pesticide might drift from the application site. In correspondence to the EPA […]

President’s Cancer Panel Says Burden of Environmentally Induced Cancer Greatly Underestimated

(Beyond Pesticides, May 11, 2010) Even with the growing body of evidence linking environmental exposures to cancer in recent years, a report released May 6, 2010 by the President’s Cancer Panel finds that the true burden of environmentally-induced cancer is greatly underestimated. The Panel’s report, Reducing Environmental Cancer Risk: What We Can Do Now, concludes that while environmental exposure is not a new front on the war on cancer, the grievous harm from this group of carcinogens has not been addressed adequately by the nation’s cancer program. “There remains a great deal to be done to identify the many existing but unrecognized environmental carcinogens and eliminate those that are known from our daily lives — our workplaces, schools and homes,” said LaSalle D. Leffall, Jr., M.D., chair of the Panel. “The increasing number of known or suspected environmental carcinogens compels us to action, even though we may currently lack irrefutable proof of harm,” he added. Beyond Pesticides applauds the chairman’s precautionary approach and encourages President Obama to heed the panel’s call to “use the power of your office to remove the carcinogens and other toxins from our food, water, and air that needlessly increase health care costs, cripple our Nation’s […]

Report Finds Government Fails to Protect Child Farm Workers

(Beyond Pesticides, May 7, 2010) Human Rights Watch has released a scathing report entitled “Fields of Peril” on the treatment of child farm workers in the United States. To compile the report, Human Rights Watch interviewed child and young adult farm laborers and parents in all regions of the country, as well as farm managers, and owners, lawyers, doctors, social workers, nurses, and government officials. A previous report entitled “Fingers to the Bone” was released in 2000. Their research shows that conditions have not changed much for the estimated 300,000 to 400,000 child farm workers in the United States. Exposure to pesticides, long hours in extreme weather, the use of heavy machinery, and demanding physical labor makes farm work one of the most dangerous jobs in the United States. According to the Centers for Disease Control’s National Institute for Occupational Safety and Health (NIOSH) farm work is the most dangerous work open to children. Yet child farm workers have much less protection under the Fair Labor Standards Act (FLSA) than children in any other industry. According to the report, even the minimal protections established by the FLSA are often ignored by employers. Impoverished farmworkers fearing the loss of their jobs […]

U.S. Supreme Court Hears Its First GE Crop Case

(Beyond Pesticides, April 30, 2010) The U.S. Supreme Court heard oral arguments on Tuesday in a case that prohibited Monsanto from selling genetically engineered (GE) alfalfa seed. A decision on the case of Monsanto Co. v. Geertson Seed Farms, the first time the Supreme Court has heard a case involving a genetically engineered crop, is expected in late June. The Center for Food Safety filed suit in 2006 on behalf of a coalition of organic farmers and environmental groups including Beyond Pesticides, arguing that the USDA violated the National Environmental Protection Act (NEPA) when it approved deregulation of GE alfalfa without an environmental impact statement (EIS). Roundup Ready Alfalfa is genetically engineered to resist the herbicide Glyphosate, sold by Monsanto under the trade name Roundup. Alfalfa is a bee pollinated crop used primarily for forage. The potential for cross pollination between GE and non-GE varieties of alfalfa is much higher than in other crops such as corn, because of the way Alfalfa is pollinated. In 2007, U.S. District Judge Charles Breyer ordered a moratorium on GE alfalfa until the USDA completed an EIS. The USDA released a draft EIS in December of 2009 again calling for deregulation of the crop. […]

Farmworker and Health Advocates Petition EPA to Cancel Carcinogenic Pesticide

(Beyond Pesticides, April 12, 2010) Environmental, public health, labor and farmworker advocacy organizations from across the country have filed a petition asking the U.S. Environmental Protection Agency (EPA) to rescind the Bush administration era approval of the highly toxic fumigant pesticide methyl iodide in light of troubling new findings uncovered in California studies. The petition was submitted on the birthday of famed farmworker rights advocate Cesar Chavez, who drew national attention to pesticide misuse on grapes in the 1980s. “In 1988, Cesar Chavez again put his life on the line to draw attention to farmworker rights when he protested the use of pesticides with a 36-day, water-only fast,” said Jeannie Economos, Pesticide Safety and Environmental Health Project Coordinator at Farmworker Association of Florida. “Over 20 years later, we should not have to be fighting the same battles. Methyl iodide use takes us in the dead wrong direction for workers, public health and the future of agriculture.” The movement to ban methyl iodide follows the legacy of Cesar Chavez: the pesticide poses significant, direct risks to farmworkers, their families and neighboring communities. Methyl iodide is a water contaminant, nervous system poison, thyroid toxicant and is listed on California’s Proposition 65 list […]

Court Rules Against Temporary Ban on GE Sugar Beets

(Beyond Pesticides, March 19, 2010) Federal district Judge Jeffrey White of the Northern District of California denied a preliminary injunction on genetically engineered (GE) sugar beets and sugar beet seeds. However, Judge White did indicate that a permanent ban may be forthcoming saying that the parties should not “assume that the Court’s decision to deny a preliminary injunction is indicative of its views on a permanent injunction” pending an Environmental Impact Statement (EIS) from the U.S Department of Agriculture’s (USDS) Animal Plant Health Inspection Service (APHIS). In the mean time, he urged the Intervenor-Defendants to “take all efforts going forward to use conventional (non GE) seed.” Judge White will begin hearing motions on a permanent ban of GE sugar beets in May with the next court date scheduled for July. “Based on today’s ruling, we are encouraged that Judge White will order permanent injunction relief,” said Paul Achitoff, attorney for Earth Justice in a release by Center for Food Safety (CFS). “We will ask the Court to halt the use of genetically engineered sugar beets and seeds until the federal government does its job to protect consumers and farmers alike.” The Plaintiffs, CFS, Organic Seed Alliance, Sierra Club, and High […]

Canceled Pesticide Kills Bald Eagles; Farmer Fined

(Beyond Pesticides, March 11, 2010) The New York State Department of Environmental Conservation (DEC) determined that a pair of bald eagles were killed and a host of other wildlife were injured after an Allegany County farmer applied a highly toxic pesticide that has been canceled for use by the U.S. Environmental Protection Agency (EPA). Following an investigation, the state DEC determined that the two bald eagles were poisoned after ingesting the improperly applied pesticide Furadan, or carbofuran, on his farm. The farmer and landowner, Richard Sekoll, was charged with and pleaded guilty to violating state pesticide laws and fish and wildlife laws and paid $3,000 in fines. After receiving a call that two dead bald eagles were found near the Genesee River last fall, DEC began an investigation and sent the eagles to the department’s Wildlife Pathology Unit. Lab results showed that the birds died of poisoning from consumption of carbofuran, which occurred after the eagles consumed prey that had ingested the pesticide. State officials with the DEC’s Division of Pesticides and the Division of Wildlife, as well as the U.S. Fish and Wildlife Service assisted in the investigation, which found that a farm within 500 yards of where the […]

European Union Approves Genetically Engineered Potato for Animal Feed and Industrial Uses

(Beyond Pesticides, March 5, 2010) The European Commission (EC) has approved the cultivation of the genetically modified (GM) Amflora Potato for feed and industrial (paper and glue) uses. Three varieties of GM corn developed by Monsanto were also approved by the EC for sale but not cultivation within the European Union (EU). Opponents fear that this decision could open the door to approval for other genetically modified (GM) crops such as Glyphosate resistant (Roundup Ready) varieties. Critics say that while not approved for human consumption, Amflora and other GM crops could still end up in the food supply, and the technology used to create these crops could lead to increased antibiotic resistance. The opposition to GM crops or “Frankenstein Foods,” as many call it, is very strong in several EU countries. Martin Haeusling, an EU Parliament and Green Party member, says that 70% of the EU population opposes genetically modified foods. This is the first time the EU has approved a GM crop since 1998 when Monsanto’s MON 810, a variety of Bacillus thuringiensis (Bt) corn was approved for human consumption. When Austria and Hungary banned the crop, the EC unsuccessfully tried to force the two nations to allow Bt […]

More Research Links Atrazine to Sexual Abnormalities in Amphibians

(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 […]

Groups Sue to Block GE Crops from Wildlife Refuge

(Beyond Pesticides, March 2, 2010) A lawsuit filed March 1, 2010 in federal court against the U.S. Fish and Wildlife Service seeks to compel the Service to uproot genetically engineered (GE) crops from its Bombay Hook National Wildlife Refuge in Delaware. As many as 80 other national wildlife refuges across the country now growing GE crops are vulnerable to similar suits. Filed in the U.S. District Court for Delaware by the Widener Environmental and Natural Resources Law Clinic on behalf of Delaware Audubon Society, Public Employees for Environmental Responsibility (PEER) and the Center for Food Safety, the federal suit charges that the Fish & Wildlife Service had illegally entered into Cooperative Farming Agreements with private parties, allowing hundreds of acres to be plowed over without the environmental review required by the National Environmental Policy Act (NEPA). In March 2009, the same groups won a similar lawsuit against GE plantings on Prime Hook National Wildlife Refuge. Ironically, Prime Hook has now been administratively incorporated into Bombay Hook, meaning that the same refuge management that is overseeing execution of the Prime Hook verdict is violating its tenets on Bombay Hook. In August 2009, several environmental groups led by the Center for Food […]

Report Shows GM Crops Fail to Tackle Climate Change

(Beyond Pesticides, March 1, 2010) Claims by the biotech industry that genetically modified (GM) crops combat climate change are exaggerated and premature, according to a new report from Friends of the Earth International. The report, “Who Benefits from GM Crops?,” examines industry claims and finds that GM crops actually increase carbon emissions while failing to feed the world. There is still not a single commercial GM crop with increased yield, drought-tolerance, salt-tolerance, enhanced nutrition or other beneficial traits long promised by biotech companies. Meanwhile, the U.S. Department of Agriculture (USDA) thinks the public does not care about GM crops and is accepting comments through this Wednesday, March 3, 2010 on allowing GM alfalfa in the U.S. The Friends of the Earth International report exposes the fact that globally GM crops remain confined to less than 3% of agricultural land and more than 99% are grown for animal feed and agrofuels, rather than food. GM crops are responsible for huge increases in the use of pesticides in the US and South America, intensifying fossil fuel use. The cultivation of GM soy to feed factory farmed animals is also contributing to widespread deforestation in South America, causing massive climate emissions. Ongoing concerns […]

Pyrethroid Pesticides in Streams Found Toxic to Indicator Species

(Beyond Pesticides, February 16, 2010) Pyrethroids, among the most widely-used home pesticides, are winding up in California rivers at levels toxic to some stream-dwellers, possibly endangering the food supply of fish and other aquatic animals, according to a study by researchers at the University of California, Berkeley, and Southern Illinois University (SIU). The study, “Urban and Agricultural Sources of Pyrethroid Insecticides to the Sacramento-San Joaquin Delta of California,” in the journal Environmental Science & Technology, is the first published work to document toxic levels in the water column as well as in the sediments at the bottom of streams. Pyrethroid insecticides, commonly used to kill ants and other insects around the home, have been found in street runoff and in the outflow from sewage treatment plants in the Sacramento, California area. The insecticide ended up in two urban creeks, the San Joaquin River and a 20-mile stretch of the American River, traditionally considered to be one of the cleanest rivers in the region. Although the pyrethroid levels were low, around 10-20 parts per trillion, they were high enough to kill a test organism similar to a small shrimp that is used to assess water safety. “These indicator organisms are ‘lab […]

India Halts Release of Genetically Modified Food Crop; Send Comments to Stop GE Alfalfa in the U.S. by February 16, 2010

(Beyond Pesticides, February 12, 2010) The Washington Post is reporting that after much protest from environmentalists, farmers, doctors, and state officials, India has imposed a moratorium on a genetically engineered (GE) variety of brinjal or eggplant. Bacillus thuringiensis (Bt) brinjal has been engineered to produce its own insecticide. It would have been India’s first GE food crop, and the world’s first GE eggplant approved for wide scale production. Bt cotton is currently India’s only genetically modified crop. Bt corn is grown in 17 countries including the United States, and China recently approved a strain of Bt rice for human consumption. A government committee approved the commercial release of Bt brinjal in October. The committee’s decision was met with protests across the country. The states of Uttarakhand, Himachal Pradesh, and Karnataka had already stated their intention to ban the crop if the federal government approves it. When Environment Minister Jairam Ramesh hosted seven public meetings around the country to debate Bt Brijal, some meetings devolved into heated shouting matches. Many protesters dressed as bright purple or green eggplants. Mr. Ramesh has since called for more independent research to ensure the crop is safe for human consumption, saying the moratorium will continue […]

Biomonitoring Data Links Brain Effects to Neurotoxic Chemical Exposure

(Beyond Pesticides, February 9, 2010) In an innovative development that could transform the way Americans view the origins of learning and developmental disabilities, the national Learning and Developmental Disabilities Initiative (LDDI) released the first-ever biomonitoring report identifying toxic chemical pollution in people from the learning and developmental disability community. Mind, Disrupted: How Toxic Chemicals May Affect How We Think and Who We Are examines 61 toxic chemicals present in project participants in the context of rising rates of autism, attention-deficit hyperactivity disorder, and other learning and developmental disabilities.   In the U. S., 5-15% of children under age 18 are affected by learning and developmental disabilities. Reported cases of autism spectrum disorders have increased tenfold since the early 1990s. Based on current research, the Centers for Disease Control and Prevention (CDC) states that 1 in 110 eight-year-old children have autism in the United States. Mind, Disrupted measured levels of a set of neurotoxic and endocrine-disrupting chemicals in the participants’ bodies. A growing body of peer-reviewed scientific research, including animal and human studies, shows that these chemicals can disrupt the development and functioning of the brain and nervous system. Eleven of the twelve study participants had detectable levels of triclosan in […]

EPA Sued for Failure to Protect Endangered Species from Pesticides

(Beyond Pesticides, February 8, 2010) The Center for Biological Diversity filed a notice of intent to sue the Environmental Protection Agency (EPA) last week. The lawsuit argues that EPA violated the Endangered Species Act when it approved 394 pesticides known to be harmful to humans and wildlife, without consulting with wildlife regulatory agencies as to the pesticides’ effects on endangered species. By registering pesticides known to harm migratory birds the EPA has also violated the Migratory Bird Treaty Act, according to the suit. The pesticides named in the suit pose a danger not only to wildlife, but to human health as well. Some of the pesticides named include 2,4-D the most commonly used pesticide in the nonagricultural sector, atrazine, triclosan, and pyrethrins. Jeff Miller, conservation advocate at the Center for Biological Diversity, said, “It’s time for the Environmental Protection Agency to finally reform pesticide use to protect both wildlife and people…Many endangered species most affected by toxic pesticides are already struggling to cope with habitat loss and rapid climate changes. For too long this agency’s oversight has been abysmal, allowing the pesticide industry to unleash a virtual plague of toxic chemicals into our environment.” The suit names 887 threatened and […]

Public Comments Needed To Stop Genetically Engineered Alfalfa

(Beyond Pesticides, February 1, 2010) Public health, environmental and organic agriculture advocates are urging the public to submit comments to the U.S. Department of Agriculture (USDA) on its draft Environmental Impact Statement (EIS) on genetically engineered (GE) alfalfa by the February 16, 2010 deadline, demanding that USDA protect organic food from GE contamination and not approve Monsanto’s GE alfalfa. USDA claims in the EIS that there is no evidence that consumers care about GE contamination of organic alfalfa. But, it is not just alfalfa that is at risk. Since alfalfa is fed to dairy cows and other livestock, organic dairy and meat products could also be affected. Last week, Beyond Pesticides reported that in the ongoing battle to stop the use of GE alfalfa seeds, Monsanto v. Geerston Seed Farms will be heard by the U.S. Supreme Court. The seed is modified to be resistant to the herbicide glyphosate, sold by Monsanto under the brand name Roundup. In 2006 the Center for Food Safety (CFS) and several other farming and environmental groups, including Beyond Pesticides, filed suit on behalf of Geerston Seed Farms. The suit led to a U.S. District Court ruling that the U.S. Department of Agriculture (USDA) violated […]

Approval of Genetically Engineered Food Crop in India Spurs Nationwide Protest

(Beyond Pesticides, January 29, 2010) A genetically engineered (GE) variety of brinjal, or eggplant, was approved by India’s Genetic Engineering Approval Committee (GEAC) last October. As the central government decides on approval of the crop’s commercial release, farmers, environmentalists, doctors, and even several state governments have mobilized in protest. India has already approved the commercial cultivation of GE cotton, but this would be the first genetically engineered food crop. Produced by Monsanto, the Bacillus Thuringiensis (Bt) brinjal is engineered to kill insects. Bt is a soil bacteria that produces compounds toxic to certain larval insects. In Bt crops, part of the bacteria’s genome has been incorporated into the plant’s genome, causing the plant to produce these same compounds. An estimated 80% of India’s cotton crop is currently grown from Bt seeds. Concerns about the approval of Bt brinjal has lead to heated protests. While India’s central government is holding a series of public meetings this month to discuss the issue, the first of these meetings ended in a shouting match between protestors and Union Minister of State for Environment and Forests, Jairam Ramesh. The Chief Ministers of several states have also written to Mr. Ramesh urging him not to rush […]

Increasing Documented Cases of Glyphosate Resistance Discussed by Scientists

(Beyond Pesticides, January 28, 2010) Scientists convening at the Pan-American Weed Resistance Conference lamented the critical issue that environmentalists have known would eventually happen, and have argued for decades: the resistance of weeds to the broadscale use of the herbicide glyphosate. The conference, hosted by Bayer Crop Science and held in Miami on January 19-21, 2010, was attended by 284 scientists and media representatives from North and South America. One of the scientists in attendance at the recent conference who offered some of the most dire outlooks on the use of glyphosate, according to The Delta Farm Press, was Stephen Powles, a professor of plant biology at the University of Western Australia, and director of the WA Herbicide Resistance Initiative (WAHRI). In some circles, he is known as an authority on herbicide resistance, and says that glyphosate “will be driven to redundancy in the cotton, corn and soybean belt.” Mr. Powles often refers to this area reaching northward into the Corn Belt down through Alabama and Mississippi as the “Glyphosate Belt.” A report that Beyond Pesticides published twelve years ago, “The Environmental Risks of Transgenic Crops: An Agroecological Assessment is the failed pesticide paradigm being genetically engineered?” argued that as […]

Media Investigation Finds Contaminated Organic Cotton Clothing

(Beyond Pesticides, January 27, 2009) Major fashion retailer H&M is under fire after media reports said that it has been selling organic cotton clothing tainted with genetically modified (GM) cotton imported from India. Consumer groups and environmental organizations are calling for an investigation into the matter, but the retailer insists there is no reason to believe that organic cotton used in its garments comes from GM seeds. H&M, a major European clothing store chain with scores of stores in the U.S., were named in a report last week in the German edition of the Financial Times, which claims there was major ”˜fraud’ taking place in the organic cotton sector. The Financial Times said that an independent testing laboratory found that organic cotton samples certified as “organic” were contaminated with genetically modified (GM) cotton material. According to the lab results, “30% of the tested samples” of organic cotton fabric contained GM cotton. Growing cotton from GM seeds is prohibited according to organic standards and the third-party certification bodies. This fallout comes at a time when scrutiny of the use of “organic” labels on various consumer goods has elevated. Last week, Organic Consumers Association (OCA), along with certified organic personal care brands, […]

GE Alfalfa Case to be Heard by U.S. Supreme Court

(Beyond Pesticides, January 25, 2010) For the first time, a case involving a genetically engineered crop will be heard by the U.S. Supreme Court. The case, Monsanto v. Geerston Seed Farms, is the most recent development in an ongoing battle to stop the use of genetically modified alfalfa seed. The seed is modified to be resistant to the herbicide glyphosate, sold by Monsanto under the brand name Roundup. In 2006 the Center for Food Safety (CFS) and several other farming and environmental groups, including Beyond Pesticides, filed suit on behalf of Geerston Seed Farms. The suit led to a U.S. District Court ruling that the U.S. Department of Agriculture (USDA) violated the National Environmental Protection Act (NEPA) by approving the sale of GE alfalfa without requiring an environmental impact statement (EIS). Monstanto was forced to stop selling the seed until a comprehensive EIS is prepared. This was the first ever moratorium in the U.S. on a genetically engineered, or modified, crop. The USDA completed its first draft of the EIS in December 2009. Brushing aside the concerns of organic alfalfa growers, consumers, and environmentalists, USDA argues for non-regulated status of GE alfalfa. According to this document, the economic gains of […]

Biocontrol Research Advances as Genomes of Parasitic Wasps Are Studied

(Beyond Pesticides, January 22, 2010) Gardeners have long turned to parasitic wasps and other beneficial insects to control unwanted insects, and new genetic research suggests even more ways to harness these species’ potential. Scientists, led by John H. Werren, Ph.D., professor of biology at the University of Rochester, and Stephen Richards, Ph.D., at the Genome Sequencing Center at the Baylor College of Medicine, have sequenced the genomes of three parasitoid wasp species, revealing many features that could be useful as a “natural” alternative to pesticides. The study, “Functional and Evolutionary Insights from the Genomes of Three Parasitoid Nasonia Species” was published in the January 15, 2010 issue of the journal Science. Already, many of these parasitoid wasps are hard at work, but because they are so small, most people are unaware of their existence. “Parasitic wasps attack and kill pest insects, but many of them are smaller than the head of a pin, so people don’t even notice them or know of their important role in keeping pest numbers down,” says Dr. Werren. “There are over 600,000 species of these amazing critters, and we owe them a lot. If it weren’t for parasitoids and other natural enemies, we would be […]

New Study Links Genetically Modified Crops to Organ Damage

(Beyond Pesticides, January 19, 2010) A study conducted by the Committee of Research and Information on Genetic Engineering (CRIIGEN) and the Universities of Caen and Rouen in France shows that three genetically modified (GM) crops have numerous adverse health effects on lab rats. The study analyzes raw data initially gathered by Monsanto to gain approval for consumption in the United States and Europe. The three crops used, NK 603, MON 810 and MON 863, are varieties of corn available in food and feed all over the world. Both MON 810 and MON863 are engineered to synthesize Bacillus Thuringiensis (Bt) toxins, a type of insecticide, and NK 603 is engineered to be resistant to the broad spectrum herbicide glyphosate, which Monsanto sells under the brand name Roundup. All three crops show varying levels of adverse health effects, primarily in the liver and kidneys, in addition to the heart, adrenal, spleen and blood cells. Researchers were assisted by Greenpeace in acquiring the data analyzed. Under a European Union directive, Monsanto should have made their raw data publicly available, but Greenpeace lawyers had to obtain some of the data through court action. The study sharply criticizes Monsanto’s data analysis and conclusions, and calls […]

Low Levels of Pesticides Slow Wild Salmon Population Recovery

(Beyond Pesticides, December 18, 2009) Biologists are finding that short-term, seasonal exposure to pesticides in rivers and basins limit the growth and size of wild salmon populations. Along with the widespread deterioration of salmon habitats, these findings show that exposure to commonly used pesticides continue to detriment the recovery of the salmons’ populations. The findings can be found in the study, “A fish of many scales: extrapolating sublethal pesticide exposures to the productivity of wild salmon populations,” in the December 2009 issue of the Ecological Society of America (ESA) journal, Ecological Applications. “Major efforts are currently underway to restore Pacific salmon habitats in an effort to recover depressed populations,” says David Baldwin, Ph.D., of the National Oceanic and Atmospheric Administration (NOAA), who co-authored the study with NOAA colleagues, “However, not much research has been done to determine the importance of pollution as a limiting factor of ESA-listed species.” The researchers studied the impact of pesticides, such as diazinon and malathion, on individual salmon using pre-existing data, and then devised a model to calculate the productivity and growth rate of the population. They used several exposure scenarios to reflect realistic pesticide use across various landscapes and over time. “An important aim […]
