(Beyond Pesticides, September 22, 2010) Consumer food buying decisions have a direct effect on the health of the environment and those who grow and harvest food. Beyond Pesticides released its expanded Eating with a Conscience guide —now updated to include the 43 of the most commonly eaten fruits and vegetables, which shows consumers why, according to the group, “food labeled organic is the right choice.” Jay Feldman, executive director of Beyond Pesticides, said, “In addition to serious health questions linked to actual residues of toxic pesticides on the food we eat, our food buying decisions support or reject hazardous agricultural practices, protection of farmworkers, and stewardship of the earth.” Eating with a Conscience explains to consumers the effect they are having on health and the environment when they purchase food grown with chemical-intensive methods, even if a large number of residues do not remain on the finished food product. The group points to organic-certified food with the USDA organic seal as “the only system of food labeling that is subject to independent public review and oversight —ensuring consumers that toxic chemicals used to kill insects and unwanted plants (or weeds) in chemical-intensive food production are replaced by management practices focused […]

(Beyond Pesticides, September 8, 2010) The U.S. Environmental Protection Agency (EPA) has received a new Biological Opinion from the National Marine Fisheries Service (NMFS) with a finding that the application of products containing any of 12 organophosphate (OP) pesticides are likely to jeopardize federally listed threatened or endangered Pacific salmon and steelhead and their designated critical habitat. The 12 OPs addressed in this Biological Opinion, issued under the Endangered Species Act, are azinphos-methyl, bensulide, dimethoate, disulfoton, ethoprop, fenamiphos, methamidophos, methidathion, methyl parathion, naled, phorate, and phosmet. This opinion concludes that EPA’s registration of pesticides containing bensulide, dimethoate, ethoprop, methidathion, naled, phorate, and phosmet are each likely to jeopardize the continued existence of one or more of the 28 endangered and threatened Pacific salmonids and are each likely to destroy or adversely modify designated critical habitat for one or more of the 28 threatened and endangered salmonids. NMFS reached this conclusion because predicted concentrations of these seven pesticides in salmonid habitats, particularly in floodplain habitats, are likely to cause adverse effects to at least one listed Pacific salmonids including significant reductions in growth or survival. EPA’s registration of bensulide, dimethoate, ethoprop, methidathion, naled, phorate, and phosmet is also likely to result […]

(Beyond Pesticides, September 7, 2010) A new study, entitled Fruit and Soil Quality of Organic and Conventional Strawberry Agroecosystems, shows organic strawberry farming results in higher quality fruit and healthier soils. A growing number of consumers are choosing organic foods, believing them to be healthier for themselves and the environment. While most environmentalists agree that organic agriculture is generally more sustainable than conventional, nutritionists who believe organic foods to be more nutritious are currently in the minority. A detailed comparison of organic and conventional strawberry farms is the first study to examine both the soil health and the nutrient content of the fruit produced. Researchers found organically produced strawberries, while slightly smaller than conventional have higher antioxidant activity, longer shelf life, and fared better in taste tests. Soils on the organic farms are also found to be healthier with higher organic matter concentration, and greater microbial biodiversity. California strawberries make up 25% of total production worldwide and 87% of U.S. production. Conventional strawberry production is notoriously dangerous for farm worker health and the environment. After phasing out the ozone depleting fumigant methyl bromide, the California government is currently considering approval of methyl iodide a chemical so carcinogenic it is actually […]

(Beyond Pesticides, August 31, 2010) As the Environmental Protection Agency (EPA) continues its review of the popular herbicide atrazine, a new study shows that male rats prenatally exposed to low doses of the gender-bending chemical are more likely to develop prostate inflammation and to go through puberty later than non-exposed animals. The research adds to a growing body of literature on atrazine, an herbicide used in agriculture, especially in corn and sugar cane production, and on golf courses and residential lawns. Atrazine and its byproducts are known to be relatively persistent in the environment, potentially finding their way into water supplies. It has been linked to a myriad of health problems in humans including disruption of hormone activity, birth defects, and cancer. The research, “Effects of prenatal exposure to a low dose atrazine metabolite mixture on pubertal timing and prostate development of male Long-Evans rats,” which is available online and will be featured on the cover of Reproductive Toxicology (Vol. 30, # 4), found that the incidence of prostate inflammation went from 48 percent in the control group to 81 percent in the male offspring who were exposed to a mixture of atrazine and its breakdown products prenatally. The severity […]

(Beyond Pesticides, August 25, 2010) Exposure to pesticides while in the womb may increase the odds that a child will have attention deficit hyperactivity disorder (ADHD), according to researchers at the University of California-Berkeley School of Public Health. Maternal metabolites of organophosphate pesticides have previously been associated with neurobehavioral deficits in children. The California researchers are studying the impact of environmental exposures on the health of women and children who live in the Salinas Valley, an agricultural region with heavy pesticide use. They tested the urine of pregnant women for pesticide residue, and then tested the behavior of their children at ages 3 ½ and 5. The 5-year-olds who had been exposed to organophosphate pesticides while in the womb have more problems with attention and behavior than did children who were not exposed. Results are published online in the study entitled, “Organophosphate Pesticide Exposure and Attention in Young Mexican-American Children,” in the journal, Environmental Health and Perspectives. Previous studies have shown that exposure to some organophosphate compounds cause hyperactivity and cognitive deficits in animals. One study published in Pediatrics earlier this year found that exposure to organophosphates in developing children might have effects on neural systems and could contribute to […]

(Beyond Pesticides, August 20, 2010) Behind closed doors this past Monday, the U.S. Environmental Protection Agency (EPA) and Bayer CropScience reached an agreement on a set of measures to gradually reduce and ultimately ban fully the use of the insecticde aldicarb in the U.S. This decision arrives on the heels of a revised risk assessment in which EPA found that babies and children under the age of five can ingest levels of the insecticide through food and drinking water at levels that exceed limits that the agency finds safe, and 25 years after 2,000 people fell ill after eating watermelons that were tainted with the pesticide. Though Beyond Pesticides applauds any decision to remove toxic chemicals from the environment, the problem with this cancellation, as with virtually all voluntary cancellations, is that the chemical can be legally used for years —eight years in this case — leaving open the opportunity for continued human and environmental exposure and harm. The decision was reached after EPA completed a revised risk assessment indicating that the pesticide does not meet the agency’s food safety standards. EPA scrutinized recent food consumption data from USDA to complete the risk assessment, which considered the percent of the […]

(Beyond Pesticides, August 17, 2010) A federal appeals court has revived the fraud and negligent misrepresentation claims by blueberry farmers in New Jersey, who say that a pesticide made by Novartis Crop Protection, Inc. reacted badly with fungicides and ruined their crops. Declaring that the lower court improperly dismissed the farmers’ state law claims as preempted by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), the federal court concluded that farmers were not suing over the alleged flaws in the warning label-which is federally regulated -rather were complaining about misrepresentations in Novartis’ marketing brochure. The case, Indian Brand Farms Inc. v. Novartis Crop Protection Inc. was filed in the 3rd U.S. Circuit Court of Appeals in New Jersey. Blueberry farmers said Novartis should have warned them that a new version of its pesticide, including diazinon as the active ingredient, also included a surfactant that reacts badly with fungicides. The promotional brochure failed to mention this reaction and when farmers mixed the diazinon pesticide with the fungicides Captan and Captec, it caused phytotoxic damage, including blotches, depressions and spots, and in some cases killed their plants. It was not clear to the appeals court that the practice of combining pesticides with […]

(Beyond Pesticides, August 11, 2010) Independent tests of sewage sludge-derived compost from the Synagro CVC plant -distributed free to gardeners since 2007 by the San Francisco Public Utilities Commission (PUC) in their “organic biosolids compost” giveaway program — have found appreciable concentrations of contaminants with endocrine-disruptive properties. These contaminants include polybrominated diphenyl ether (PBDE) flame retardants, nonylphenol detergent breakdown products, and the antibacterial agent triclosan. The independent tests were conducted for the Food Rights Network by Robert C. Hale, PhD of the Virginia Institute of Marine Sciences. The antibacterial triclosan, an endocrine disruptor, was also found in the sewage sludge compost, at an average of 1,312 ng/g (or ppb). Last week, the Centers for Disease Control updated their National Report on Human Exposure to Environmental Chemicals and noted that triclosan levels in people increased by over 41% between just the years 2004 and 2006. Also last week, a scientific paper showed that triclosan from sewage sludge can be taken up by soybean plants and translocated into the beans themselves, then consumed by people and animals. PBDEs are persistent and bioaccumulate in the environment and elevated levels have been found in California citizens. The average total of the PBDE congeners tested […]

(Beyond Pesticides, August 9, 2010) Two separate findings that showcase increased exposure and potential for exposure in humans to the toxic chemical triclosan add to the mounting evidence that the non-medical use of this chemical should be banned. Newly released data from the Centers for Disease Control and Prevention (CDC) finds that levels of triclosan in humans have increased by 50% since 2004. Moreover, a study by the University of Toledo shows that triclosan and triclocarbon, a similar compound, can enter the food chain through use of contaminated water or fertilizer on agricultural crops. CDC’s updated National Report on Human Exposure to Environmental Chemicals finds that the 50% increase in levels of triclosan is across all demographics in the U.S. population. Data was collected on the concentration of triclosan in urine. Affluent people and those over the age of 20 have the highest concentrations of triclosan in their urine. The study released by the University of Toledo, “Uptake of Pharmaceutical and Personal Care Products by Soybean Plants from Soils Applied with Biosolids and Irrigated with Contaminated Water,” examines the potential for crops to take up contaminants such as triclosan from water or fertilizer. Conventional crops are often fertilized with sewage […]

(Beyond Pesticides, August 6, 2010) Organic farmers and gardeners across a Washington state county suspect that herbicide-contaminated manure and compost obtained from non-organic farms and dairies are responsible for severe crop loss reported throughout the region, raising questions about the adequacy of the U.S. Environmental Protection Agency’s (EPA) pesticide registration process. Tests of soil and tissue samples of local dairy manure that is used in soil and compost mixtures revealed small amounts of aminopyralid, a potent and persistent herbicide approved for use by EPA in 2005. Aminopyralid is generally used for weed control in pastures and fields that grow silage crops for dairy cows. When cows eat the grass that has been treated with the chemical, it passes through them unchanged and remains in their manure in concentrations that can still be high enough to damage broadleaf crops if the manure is used to fertilize them. Aminopyralid is produced by Dow AgroSciences, a subsidiary of Dow Chemical Co., and often manufactured under the product name Milestone. Former coordinator of the Washington State University master gardeners’ program Jill Cotton has noticed the damage in her garden and said reports continue to filter in from other gardens around the county. One Whatcom […]

(Beyond Pesticides, August 5, 2010) A 400-year old large old grape vine considered to be the nation’s oldest in Manteo, North Carolina and known lovingly as “Mother Vine,” is slowly recovering from a powerful dose of herbicide sprayed by a utility company. The Virginia-based Dominion Power Company contracted Lewis Tree Service to spray power poles along the roads in the Manteo in May. The herbicide they used, Garlon3A, was accidentally sprayed on a tiny shoot from the vine that had grown a few feet up a pole on 84-year old Jack Wilson’s property. Unaware of the recent herbicide spraying by the utility power company, he noticed various brown, dead sections that began to appear in the plant in May. Not only did the vine suffer, but about 10 feet of a nearby hedge died, along with three limbs of a large pecan tree that had to be trimmed. The active ingredient in Garlon 3A, a Dow Chemical product, is triclopyr. It is a systemic herbicide which means that the poison spreads from the ends of the vine back toward the root. As a broadleaf weed killer, triclopyr is frequently used along rights-of-way and on industrial sites. In laboratory tests, triclopyr […]

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

(Beyond Pesticides, July 30, 2010) Adding to a campaign that Beyond Pesticides launched in 2004 to alert the public and pressure government to restrict the highly toxic antibacterial chemical triclosan -commonly found in antibacterial soaps and household and consumer products, the Natural Resources Defense Council (NRDC) filed a lawsuit earlier this week against the Food and Drug Administration (FDA) for failing to issue a final rule regulating the chemical. The lawsuit follows on the heels of two petitions filed by Beyond Pesticides and Food and Water Watch in 2009 and 2010 with FDA and the U.S. Environmental Protection Agency (EPA), respectively, to ban the chemical. Because of the widespread poisoning and environmental contamination caused by triclosan, the petitions cite numerous violations of statutory duties under the Federal Food, Drug and Cosmetics Act, Federal Insecticide, Fungicide, and Rodenticide Act, Clean Water Act, Safe Drinking Water Act, and Endangered Species Act. The NRDC lawsuit adds yet another dimension to the legal violations involving agency malfeasance on triclosan by asking the court to impose a strict deadline for FDA to finalize a proposed rule that has been pending for 32 years and could ban many uses of triclosan and its chemical cousin triclocarban. […]

(Beyond Pesticides, July 27, 2010) Groups filed a lawsuit in federal court to force the Environmental Protection Agency (EPA) to decide whether or not it will cancel all remaining uses and tolerances for the pesticide chlorpyrifos, which has been banned for residential use, but continues to expose farmworkers and consumers through its use in agriculture. In September 2007, the Natural Resources Defense Council (NRDC) and Pesticide Action Network North America (PANNA) filed a petition with EPA asking the agency to ban chlorpyrifos. In the nearly three years since, the agency has not responded. NRDC and PANNA v. EPA, filed by the nonprofit environmental law firm Earthjustice on July 22, 2010, would force EPA to make a decision on the pesticide’s ban. “This dangerous pesticide has no place in our fields, near our children, or on our food,” said Earthjustice attorney Kevin Regan. “We’re asking a court to rule so that EPA will finish the job and ban this poison.” According to Beyond Pesticides, EPA’s 2000 negotiated settlement with Dow AgroSciences, which allows the highest volume chlorpyrifos uses to continue, represents a classic failure of the risk assessment process (including the so-called cumulative risk assessment which accounts for all chemicals with […]

(Beyond Pesticides, July 23, 2010) A new study published in BioMed’s online journal, Environmental Health, links endocrine disrupting pesticides and other chemicals in household cleaning products to an elevated risk of breast cancer. Researchers at the Silent Spring Institute in Newton, MA and Boston University found that women who use household cleaners more often have double the risk of breast cancer, compared to women who use household cleaners less frequently. The study includes over 1,500 women selected from Cape Cod, MA and found a correlation between cases of breast cancer and the number of women who reported using household cleaners, particularly solid, slow-release air fresheners when used more than seven times a year, and mold removers when used more than once a week. The antimicrobials, phthalates and alkylphenolic surfactants often found in mold and mildew products are associated with various health and environmental issues. The antimicrobial triclosan for example, can cause skin irritation, allergy susceptibility, bacterial and compounded antibiotic resistance, and dioxin that jeopardizes fragile aquatic ecosystems. The study highlights methylene chloride (in some fabric cleaners), nitrobenzene (soaps, polishes), perfluorinated compounds (stainresistant, waterproof coatings), phthalates (surfactants), alkylphenols (solvents), parabens (preservatives), triclosan, and polycyclic musks (fragrance) as ingredients of concern. Past […]

(Beyond Pesticides, July 22, 2010) In a press release submitted last week, the Monsanto Company, Inc. announced that it has taken a vital step towards commercializing a new soybean product that is tolerant to the neurotoxic pesticide dicamba by completing its regulatory submission to the U.S. Department of Agriculture (USDA) for dicamba-tolerant soybeans. Monsanto expects to complete regulatory submission to the USDA and key global markets in the coming months. The dicamba tolerance trait is expected to also be stacked with the glyphosate-resistant, or “Roundup Ready” soybean trait upon commercialization. While Monsanto claims that this is a “highly effective and economical weed control package,” it is likely to be similar to Roundup (glyphosate) Ready crops, just another way to sell more pesticide product. Monsanto is banking on the idea that mixing dicamba with glyphosate will help manage the hard-to-control broadleaf weeds in chemical-intensive farming systems, targeting both pre-plant and post-emergence weed control in an effort to reduce resistance. In a report published last year, analysts found that genetically engineered (GE) crops have been responsible for an increase of 383 million pounds of herbicide use in the U.S. over the first 13 years of commercial use of GE crops (1996-2008). The […]

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

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

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

(Beyond Pesticides, July 15, 2010) Swiss chemical manufacturing giant Syngenta, one of the makers of the commonly used and heavily scrutinized pesticides atrazine, are speaking out against anti-pesticide activists and the U.S. Environmental Protection Agency’s (EPA) review of atrazine. Despite mounting peer-reviewed scientific literature and research, Syngenta refuses to acknowledge the dangers of atrazine and, according to Legal Newsline, claims that the review is “redundant,” and merely “an unprecedented war on agriculture by anti-pesticide activists.” The company, which made over $11 billion in sales in 2009 even accuses the Natural Resources Defense Council (NRDC), which has spearheaded a campaign to persuade EPA to initiate reviews, of being “slick” and “well-funded.” Other critics of the agency’s decision include the American Council on Science and Health (ACSH), a group that has in the past received funding from Monsanto and Union Carbide (according to the group Center for Science in the Public Interest, ACSH stopped disclosing corporate donors in the early 1990’s). Dr. Gilbert Ross, medical director of ACSH told Legal Newswire that they believe EPA Administrator Lisa P. Jackson to be “cooperating with, if not spearheading, a broad-based activist agenda.” An article by The Huffington Post Investigative Fund published last week, however, […]

(Beyond Pesticides, June 30, 2010) The U.S. Environmental Protection Agency (EPA) approval process for thousands of antimicrobial products is woefully inadequate, according Public Employees for Environmental Responsibility (PEER). Despite a growing body of scientific evidence about the side-effects of these products, EPA rubberstamps registrations without duly considering an array of potential public health and environmental impacts. Antimicrobials are now a billion dollar business with more than 5,000 such products currently registered with EPA. Initially designed for hospitals and clinics, antimicrobial pesticides are today found in products ranging from household cleaners to mattresses and bedding, cosmetics, toys, toothpaste and even chopsticks. Antibacterial products are being marketed to the health conscious without firm evidence of real benefits and amid growing concern about downstream consequences. One prime example of this is the antibacterial pesticide triclosan that is formulated into hundreds of personal care products, toys and textiles. Studies show that triclosan is an endocrine disruptor, accumulates in human fatty tissue and can influence the onset of bacterial resistance. Beyond Pesticides, Food and Water Watch and several other groups petitioned FDA in 2009 and EPA in January 2010, calling for the ban of triclosan citing the possibility of bacterial resistance to antibacterial substances and […]

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

(Beyond Pesticides, June 25, 2010) Two new studies published in the journal Environmental Science and Technology confirm that the majority of toxic contamination threatening national parks originates from agricultural pesticides and industrial operations. In one study an international group of scientists conducted research from 2003-2005 and detected elevated concentrations of various dangerous pesticides in all eight of the national parks and preserves. The other study collected samples of air, water, snow, sediment, lichens, conifer needles, and fish at remote alpine, subarctic, and arctic sites. Researchers found that these samples contained four current-use pesticides including dacthal (DCPA), chlorpyrifos, endosulfans, and y-hexachlorocyclohexane (HGH) as well as four historic-use pesticides including dieldrin, a-HCH, chlordanes, and hexachlorobenzene (HCB). Pesticide concentrations in snow are highest in Sequoia, Kings Canyon, Rocky Mountain and Glacier National Parks. Concentrations in vegetation are mostly dominated by endosulfan and dacthal, and are highest in Yosemite, Kings Canyon, Glacier, and Great Sand Dunes National Park and Preserve. Fish samples also show elevated concentrations of dieldrin and DDT (one of the first pesticides to be banned in 1972 because of Rachel Carson’s Silent Spring). Cold temperatures in alpine or arctic ecosystems tend to concentrate pesticides, which can also bioaccumulate in the local […]
