(Beyond Pesticides, February 21, 2019) In 2018, the Environmental Protection Agency (EPA) approved 16.2 million acres of crops to be sprayed with the bee-toxic insecticide sulfoxaflor under an emergency exemption. Sulfoxaflor was used in 18 different states on cotton and sorghum — plants known to attract bees. In response to a lawsuit headed by beekeepers, the EPA reclassified sulfoxaflor in 2016 and, recognizing its toxicity to bees, prohibited use on crops that draw in these pollinators. However, Section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) gives the EPA authority to permit temporary emergency use of unapproved pesticides. This loophole is used regularly in response to predictable stressors. “Emergency” use was approved 78 times for sulfoxaflor on sorghum and cotton between 2012-2017. Sulfoxaflor is a systemic insecticide that acts similarly to neonicotinoid pesticides. After application, the chemical is absorbed and distributed throughout the plant, including pollen and nectar. These kinds of chemicals are selective agonists of insects’ nicotinic acetylcholine receptors—they bind to the receptor and cause it to activate. The impact on foraging bees is sublethal, but devastating on a population level. Even at low levels, sulfoxaflor impairs reproduction and reduces bumblebee colony size. Sufloxaflor is functionally identical to […]

(Beyond Pesticides, February 20, 2019) Women exposed to DDT during ‘early windows of susceptibility’ in their childhood are at increased risk of developing breast cancer, according to new research published in the Journal of the National Cancer Institute. Nearly 75 years after the chemical was first used in the U.S., and 50 years after its ban, DDT is continuing to adversely affect the health of Americans. The data brings needed attention to the dangers of early-life pesticide exposure, and underlines the need to take a precautionary approach to the introduction of biocides in our environment so that future generations do not suffer from the same mistakes of the past. “What we have learned is that timing really matters. We know that if harmful exposures occur at times when breast tissue is rapidly changing, such as during puberty, they impact breast development in ways that can later result in cancer,” said lead author Barbara A. Cohn, PhD, of the Public Health Institute’s (PHI) Child Health and Development Studies. “The research published today suggests that DDT affects breast cancer as an endocrine disruptor, that the period of time between first exposure and cancer risk seems to be around 40 years–and that other […]

(Beyond Pesticides, February 15, 2019) A study, published in January 2019 in the journal Environmental Health, demonstrates that consumption of organic foods reduces significantly the levels of synthetic pesticide residues in the bodies of U.S. children and adults. Pesticide residues are found four times as frequently in conventionally grown food as in organically produced foodstuffs. Although the number of subjects in this study was relatively small, the results point to the importance of organics, and add to the evidence that organic food production and consumption are key to protecting human health. Study subjects comprised members of racially diverse families — from Oakland, Minneapolis, Baltimore, and Atlanta — who did not typically consume an organic diet. Study participants, ages 4 to 52, ate their typical diet of conventionally grown foods for five days; for the following six days, they switched to a certified organic diet (provided by researchers) for consumption at home, work, school, or daycare, including all foods and beverages other than water. Urine samples were gathered prior to the “organic” days, and first thing on the morning after those six days. Fourteen different pesticides and metabolites were present in all participants’ urine in the “pre-organic” analysis; following the organic diet […]

(Beyond Pesticides, February 13, 2019) Friends of the Earth (FOE) released a report last week again showing pesticide residues in the food supply. The report, Toxic Secret, found store and name brand foods produced and sold by the top four U.S. food retailers — Kroger (NYSE:KR), Walmart (NYSE: WMT), Costco (NYSE:COST) and Albertsons — contain residues of toxic pesticides linked to a range of serious health and environmental problems. Among the pesticides found is the herbicide glyphosate, confirming residue testing results found in numerous studies. Glyphosate, the active ingredient in Roundup, has has been detected in popular foods, including “100% pure” honey, Doritos, Oreos, Goldfish, Ritz Crackers, German beers, California wines, and UK bread. Glyphosate has been ranked as potentially cancer causing in humans and adversely affects the human gut microbiome. See Residue Testing Find More Glyphosate in Popular Cereals. The FOE study finds that oat cereals, apples, applesauce, spinach and pinto beans at the retailers contained detectable amounts of glyphosate, organophosphates and neonicotinoids. The average level of glyphosate found in cereal samples (360 parts per billion) was more than twice the level set by scientists at Environmental Working Group for lifetime cancer risk for children. The average level of glyphosate found in pinto beans (509 ppb) was more […]

(Beyond Pesticides, February 11, 2019) Aminocyclopyrachlor (ACP) is a tree-killing pesticide masquerading as a broadleaf herbicide. The Oregon Department of Agriculture (ODA) has the opportunity to lead the country in banning this inherently dangerous chemical. According to ODA, nearly 1,500 dead or dying trees have been reported along Oregon’s iconic Interstate 20, home to old growth ponderosa pines. Many of these 150- to 300-year old trees are now dead from ACP exposure. ODA indicated that “because [ACP] is a relatively new herbicide it is unknown how many trees stressed from past applications of [ACP] will die in the future.” Even at tiny levels, ACP run-off and drift kills trees. Tell Oregon’s Department of Agriculture to lead the country in completely banning its use. In 2014, DuPont chemical company settled a nearly $2 million lawsuit with the U.S. Environmental Protection Agency (EPA) after the herbicide (under the brand name Imprelis®) was found to kill trees at golf courses, homeowners associations, businesses, and private residences. Despite this history, regulators left ACP on the market. Its use was banned on lawns and turfgrass, but allowed for roadside rights-of-way. A couple years ago, Bayer purchased the rights to ACP from DuPont and continues to market […]

(Beyond Pesticides, February 7, 2019) A new study, released in Environmental Science and Policy, systematically reviews all state-level pollinator protection acts passed since 2000 and makes a somewhat dim diagnosis: as a rule, state policies fall far below the mark for protecting invaluable ecosystem services and ensuring long-term, sustainable food production. Authors judge the legislation against a set of pollinator protection policy benchmarks established in 2016 by a group of scientists from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). Citing the ten policy recommendations laid out by IPBES experts, researchers point to the failure of all enacted state policies to address three main target areas – (1) to improve genetically modified crop risk assessment, (2) to incentivize farmers to make the switch from agrochemical dependence to sustainable benefits from ecosystem services, and, critically, (3) to support diversified farming systems. Beyond Pesticides notes one additional missed target: (4) funding for research on organic, diversified, and ecologically intensified farming. The study includes a total of 109 state laws passed from 2000 to 2017, which authors tracked down by searching usa.gov and state legislative websites and by submitting requests to state librarians. To uncover common themes and patterns among these […]

(Beyond Pesticides, February 6, 2019) The American Association for the Advancement of Science (AAAS) has awarded two researchers the group’s Scientific Freedom and Responsibility Award for their work uncovering the link between glyphosate and chronic kidney disease (CKD), which has killed at least 25,000 Sri Lankans and 20,000 Central Americans. Award recipients Sarath Guanatilake, MD, and Channa Jayasumana, PhD, faced death threats and claims of research misconduct as they went toe to toe with agrichemical industry giant Monsanto (now Bayer’s Monsanto), the major manufacturer of glyphosate-based products like Roundup. “To right a wrong when significant financial interests are at stake and the power imbalance between industry and individual is at play takes the unique combination of scientific rigor, professional persistence and acceptance of personal risk demonstrated by the two scientists recognized by this year’s award,” says Jessica Wyndham, director of the Scientific Responsibility, Human Rights and Law Program at AAAS. In the mid-90s, reports began to emerge of Sri Lankan rice farmers – many otherwise healthy, young adults, succumbing to CKD. Dr. Gunatilake, a researcher at California State University, Long Beach (CSULB), was hired by the Sri Lanka Ministry of Health to investigate the cause of the disease. Around the […]

(Beyond Pesticides, February 5, 2019) Linuron, an herbicide registered for use by the U.S. Environmental Protection Agency (EPA), yet recently banned in Europe due to health concerns, appears to trigger inflammatory signals that have been linked to the onset of Multiple Sclerosis (MS). This new evidence, published in the journal Cell by researchers at Brigham and Women’s Hospital in Boston, MA, indicates that exposure to chemicals and pesticides in the environment may be a risk factor in the development of neurodegenerative diseases. “We created a platform to systematically investigate the understudied effects of environmental exposures,” said study coauthor Francisco Quintana, PhD. “The goal of our work is to return results that can guide future epidemiological studies and identify actionable targets.” Researchers began their investigation with 976 chemicals identified by EPA’s ToxCast program, an inventory of compounds that have undergone screening for a battery of laboratory tests. Within that inventory, 75 chemicals, including linuron, were found to interfere with the signaling pathways linked to MS. To confirm the adverse impacts, scientists used the embryos of zebrafish, animals often used as models in laboratory research. The zebrafish embryos were altered to contain low levels of myelin, a protein that protects nerve cells, as […]

(Beyond Pesticides, February 1, 2019) Prior to a pesticide ban taking effect in Montgomery County Maryland Parks, the Department of Parks announced in mid-December 2018 that it would discontinue the use of glyphosate-based herbicides through March 2019. The agency has used these hazardous herbicides as part of its IPM (Integrated Pest Management) program for weed management. Montgomery Parks indicates it will release further information on the use of glyphosate in mid-March. In November last year, Montgomery County Council member Tom Hucker wrote to the head of Parks, supported by a community-wide petition, urging that glyphosate be banned immediately, pending implementation of the county ban. He cited the finding of the International Agency for Research on Cancer’s (World Health Organization) finding that the chemical probably causes cancer in humans and the $289 million jury verdict last year that the chemical caused a school groundskeeper’s non Hodgkin lymphoma. In 2016, Montgomery Parks instituted a pesticide reduction program in compliance with Montgomery County, Maryland’s 2015 adoption of County Code 33B, which aimed to regulate use of pesticides on county-owned property, including parks, and on private property. In 2017, a Montgomery Circuit Court overturned the portion of the law pertaining to a ban on private […]

(Beyond Pesticides, January 28, 2019) A  September 2018 report from the Office Inspector General (OIG) of the U.S. Environmental Protection Agency (EPA) identified issues important to protecting health and the environment. The EPA’s response to the report left many of these problems unresolved. Measures and Management Controls Needed to Improve EPA’s Pesticide Emergency Exemption Process (Report No. 18-P-0281, September 25, 2018), finds that the agency’s practice of routinely granting “emergency” approval for pesticides through its Section 18 program does not effectively measure risks to human health or the environment. Tell Congress to Ask the EPA Administrator to Close the “Emergency” Pesticide Use Loophole, and Adopt All the Recommendations of the Office of the Inspector General. Under Section 18 of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA has the authority to approve the temporary emergency use of unapproved pesticides if the agency determines the pesticide is needed to prevent the spread of an unexpected outbreak of crop-damaging insects, for example. But this provision has been widely abused. The inspector general recommends EPA “develop and implement applicable outcome-based performance measures to demonstrate the human health and environmental effects of the EPA’s emergency exemption decisions.” EPA disagreed and said, [T]he development […]

(Beyond Pesticides, January, 23, 2019) Individuals that have been acutely poisoned by pesticides at some time in their life may be more likely to lose their sense of smell, according to a recent study published in Environmental Health Perspectives.  Researchers focused on the effect of high pesticide exposure events (HPEE), such as a pesticide spill or other incident, on a farmers’ ability to smell later in life. This is the first study to indicate pesticide exposure may result in olfactory impairment. Farmers from Iowa and North Carolina enrolled in an ongoing U.S. Agricultural Health Study have been asked about their pesticide use roughly every 5 to 6 years since 1993. In the most recent survey, taken from 2013-2015, farmers were asked additional questions about HPEE in their lifetime and whether they had a significantly decreased or impaired sense of smell. “Studying farmers gives us more reliable data on pesticide exposures than if we had studied the general population,” says Honglei Chen, MD, PhD, lead author and professor of epidemiology at Michigan State University in a press release. “Because they use pesticides more and it’s part of their job, they’re more likely to remember what pesticides they used and in cases […]

(Beyond Pesticides, January 22, 2019) Earlier this month, U.S. Representative Nydia Velásquez (D-NY) introduced The Ban Toxic Pesticides Act, H.R.230 which bans the insecticide chlorpyrifos from commerce. Chlorpyrifos is a toxic chemical that has been linked to damaging and often irreversible health outcomes in workers, pregnant women, and children. As a result of a revised human health risk assessment, the Environmental Protection Agency (EPA) developed a regulation to ban chlorpyrifos in 2016. Under the Trump Administration, the EPA has taken steps to reverse the regulation. “It’s unconscionable for EPA to turn a blind eye as children and workers are exposed to this poison,” Velázquez said.  “If the EPA won’t do its job when it comes to chlorpyrifos, then Congress needs to act – and do so quickly.” Ask your U.S. Representative to Co-Sponsor H.R. 230 to Stop the Use of the Toxic Insecticide Chlorpyrifos, which Is Damaging Children’s Brains.  Chlorypyrifos is a widely used pesticide. Agriculture companies annually spray 6 million pounds of the substance on crops like citrus, apples, and cherries.  In the same family as Sarin gas, the substance was initially developed prior to World War II as a chemical weapon. It can overstimulate the nervous system to cause […]

(Beyond Pesticides, January 18, 2019) A new analysis by Charles Benbrook, PhD, published in the journal Environmental Sciences Europe, adds to the chronicle of the failures of the U.S. Environmental Protection Agency (EPA) to protect human health from toxic pesticides, and in this subject instance, from glyphosate. Meanwhile, a French Court has pulled the license for a Roundup product, citing the French government’s failure to protect public health. In his paper, Dr. Benbrook examines the divergent positions on the carcinogenicity of glyphosate — the active ingredient in a number of herbicides, most notably Monsanto’s (now Bayer’s) Roundup — taken by the International Agency for Research on Cancer (IARC) and by EPA. The paper calls out EPA’s handling of science related to the safety of glyphosate, suggesting that the agency has discounted evidence of the compound’s association with genotoxicity — destructive effects on cellular genetic material that can cause mutations — which can result in cancer. Dr. Benbrook is an American agricultural economist, former executive director of the National Academy of Sciences board on agriculture, and former research professor at the Center for Sustaining Agriculture and Natural Resources at Washington State University. He has long studied pesticide use related to genetically engineered […]

(Beyond Pesticides, January 16, 2019) Preliminary counts in California indicate the western monarch butterfly population dropped 86% from 2017 to 2018. The survey is a result of an annual effort by volunteer citizen scientists, organized by the nonprofit organization Xerces Society. If the trend from the initial sample (97 sites) holds true, the population of overwintering butterflies is estimated to be less than 30,000 – 0.05% of its historical size. Full and vetted results will be published in late January. To get an accurate count of monarch populations, volunteers follow a monitoring guide, which recommends beginning a count on a still, cool, and dry morning so that monarchs are still clustered together. Volunteers count a small cluster of monarchs and then extrapolate that number to arrive at a total for the larger cluster they’re observing. Citizen science has been crucial to understanding the decline of monarchs and insects worldwide. As covered by The New York Times, the current “Insect Apocalypse” has largely been documented by volunteers. The dismal numbers recorded this year are potentially disastrous, as the predicted extinction threshold for overwintering western monarchs is a population of 30,000. However this threshold, based on population densities needed for thermoregulation and mating […]

(Beyond Pesticides, January 14, 2019) Tell Congress to stop the Trump administration from opening the floodgates to permit widespread use of antibiotics in citrus production (grapefruits, oranges and tangerines). Despite the building national and international crisis of deadly bacterial resistance to antibiotics, this new allowance would expand on an emergency use decision the Environmental Protection Agency made in 2017. It permits up to 480,000 acres of citrus trees in Florida to be treated with more than 650,000 pounds of streptomycin per year; 23,000 citrus acres in California will likely be treated annually. The World Health Organization has called bacterial resistance “one of the biggest threats to global health, food security, and development today.” Tell your U.S. Senators and Representative to urge EPA to reject the use of antibiotics in food production, including citrus production. The two approved antibacterial chemicals to be used as pesticides in citrus production are streptomycin and oxytetracycline. Their use was permitted by the U.S. Environmental Protection Agency (EPA) under an emergency exemption in May, 2017 for a citrus greening disease caused by the bacterium Candidatus Liberibacter asiaticus (CLas) in Florida citrus crops through December of 2019. The Environmental Protection Agency announced March 15, “EPA is issuing these tolerances without notice and opportunity […]

(Beyond Pesticides, January 8, 2019) At the end of December, the U.S. Department of Agriculture (USDA) finalized its rule regarding the disclosure of genetically engineered (GE) ingredients in consumer foods. After years of local, state and federal pressure to implement a clear, concise labeling requirement for GE foods, advocates say USDA’s rule is a failure, and a capitulation to agrichemical corporations that promote GE farming systems. According to U.S. Representative Chellie Pingree (D-ME), speaking with the Portland Press Herald, the new rule is “an insult to consumers.” She said, “These labels should give people the facts of whether ingredients in their food have been genetically altered, plain and simple.” Rather than the plain and simple language urged by Rep Pingree and other GE labeling advocates, USDA determined to move forward with muddled verbiage that is certain to confuse consumers. GE products will not defined by a term Americans are familiar with, such as GE or GMO. Instead, the term USDA will require on product labels is “bioengineered.” USDA is allowing companies to choose one of the following methods to alert consumers to the presence of GE ingredients in their foods: Inclusion of a “bioengineered” or “derived from bioengineering” symbol alongside […]

(Beyond Pesticides, January 4, 2019) First, the good news: plaintiffs in a 2013 lawsuit against the Environmental Protection Agency (EPA) can allow themselves a small victory dance. In that suit, plaintiffs made a number of claims related to EPA’s failure to protect pollinators from dangerous pesticides, its poor oversight of the bee-killing pesticides clothianidin and thiamethoxam, and its practice of “conditional registration,” as well as labeling deficiencies. The parties in the suit negotiated a settlement, as directed by a federal judge (see below), that was signed in October 2018 and portends some positive movement in curtailing the use of some toxic pesticides [12 products, each of which contains chlothianidin or thiamathoxam as an active ingredient] that harm pollinators in particular, as well as other organisms and the environment. It also establishes a public process for EPA to consider requiring whole formulations of pesticide products during registration, and redefining EPA’s interpretation of law that allows seeds treated with bee-toxic pesticides to escape regulation as a pesticide. The suit was brought by a number of individual beekeepers and several organizations, including Beyond Pesticides, Center for Food Safety (CFS), Sierra Club, and Center for Environmental Health, and named as defendants Steven Bradbury, then-director of the […]

(Beyond Pesticides, January 2, 2019) The “indoor microbiome” of yoga studios and other athletic facilities often contain significant levels of antibacterial chemicals like triclosan, which show up in dust and breed antibiotic resistance, according to research published last month in the journal mSystems. Triclosan may be banned from hand soaps, but its continued use in a myriad of other products, from disinfectant sprays to impregnated clothing, yoga mats, and other work-out equipment makes it difficult to avoid this now-ubiquitous chemical. This is a public health concern because these antibacterial or antimicrobial chemicals are link to antibiotic-resistant bacteria. Antibiotic resistance kills over 23,000 people each year, according to the Centers for Disease Control and Prevention (CDC). In addition to the CDC, the World Health Organization has cited this escalating problem as become one of the biggest public health challenges of our time. Many people may suspect their gym or yoga study is not a germ-free location, but attempts to address these germs through antibacterial sprays or impregnated yoga mats and other surfaces, may be exacerbating the issue—doing much more harm than good. The continued detection of triclosan and its impacts at new and unexpected locations are feeding renewed calls for a complete ban on […]

(Beyond Pesticides, December 21, 2019) A study at the University of Maine (UMaine) finds that adding blackberry leaf litter in stormwater catch basins creates an “ecological trap,” enticing mosquito females to lay eggs in sites unsuitable for larvae survival. Employing this new and incredibly viable “attract-and-kill’ tool for mosquito control shows potential for preventing the breeding of mosquitoes that may carry insect-borne diseases, especially in urban environments. Stormwater catch basins regularly accumulate leaf litter, which serve as habitat for the mosquito species Culex pipiens (Cx. Pipiens) that may carry West Nile virus. Previous University of Maine research discovered decomposing leaf litter from Amur honeysuckle (Lonicera maackii) and common blackberry (Rubus allegheniensis) produces chemical compounds that attracts and stimulates Cx. Pipiens female to oviposit, or lay eggs. Investigating the attractiveness and lethality of varying catch basin conditions to mosquitoes, researchers hypothesized that blackberry leaf litter could be shown to be lethal to developing mosquito larvae, and, therefore, act as a natural ecological trap for Cx. Pipiens. Five varying treatments were applied to a total 50 catch basins. Treatments included (1) all debris dredged weekly throughout the duration of the study, (2) no change to debris naturally occurring in catch basins, (3) […]

(Beyond Pesticides, December 20, 2018) Using low doses of the herbicide paraquat and common proteins found in food called lectins, researchers were able to recreate the symptoms of Parkinson’s disease in rats. Results of this study, published in the journal Parkinson’s disease, provide scientists with fresh insights into the development of the disease, and a new model to test potential remedies. Paraquat, a neurotoxic herbicide with a well-established body of literature linking it to Parkinson’s disease, is currently undergoing a registration review by the U.S. Environmental Protection Agency, and groups like the Michael J Fox Foundation are calling for its ban. Researchers based their study on the Braak Staging hypothesis of Parkinson’s, which posits that the disease is brought on by foreign agents entering the body through the gut or nose and making their way to the brain. Rats were exposed to low doses of paraquat combined with lectin every day for a week. After two weeks, the animals’ motor function was tested and compared to an unexposed control group. Rats exposed to lectin and paraquat exhibited Parkinson-like symptoms. Primary author R. Alberto Travagli, PhD, notes, “After observing that these animals did indeed show symptoms of Parkinsonism, we wanted to […]

(Beyond Pesticides, December 18, 2018) The ingredients not listed on a pesticide product are not fully reviewed for their adverse effects may be the most toxic chemicals in the formulation. Recent research, Toxicity of formulants and heavy metals in glyphosate-based herbicides and other pesticides (Toxicology Reports 5, 2018), by Defarge, de Vendômois, and Séralini demonstrates the need to disclose and test all ingredients in pesticide products, as well as the full formulation that includes “inert” or nondisclosed ingredients. While glyphosate/Roundup is obviously not allowed to be used in organic production, this research reaffirms the need to evaluate full formulations of substances allowed for use in organic. The research on glyphosate tested the toxicity of the herbicide glyphosate, “inerts” in glyphosate-based herbicides (GBH), and the pesticide formulations–looking at toxicity to target organisms, toxicity to human cells, and endocrine-disrupting activity. In addition to the GBH products, the researchers studied a number of other pesticides. Tell NOP and USDA that “inerts” used in organic production must receive full review by the NOSB. “Inert” ingredients are allowed in pesticides used in organic production as well as those used in chemical-intensive production. The National Organic Program (NOP) allows “inerts,” permitted in conventional production and formerly listed […]

(Beyond Pesticides, December 12, 2018)  Costa Rica is currently experiencing exponential growth in its banana and pineapple farming industries and with it an increase in intensive pesticide applications. Recent studies in Costa Rica identified evidence of increasing fur discoloration in black mantled howler monkeys ((Alouatta palliata) as a result of their exposure to sulfur-based pesticides. Coloration in Howler monkeys are limited to black, gray, and dark brown, but researchers found several monkeys with yellow patches on their tails and legs. The change in pigmentation is directly correlated to the consumption of plants inadvertently exposed to sulfur-based pesticides sprayed at (and drifting from) nearby farms. The use of pesticides is not only hazardous to nearby wildlife, but communities as well. It is an issue that seems to play out repeatedly both in Costa Rica and in the U.S. The use of pesticides, and more importantly pesticide drift, continues to be a pervasive issue with severe human and environmental health consequences. Pesticide drift occurs in the form of mist, particles, or vapor (gas) and are usually carried by air (and oftentimes water) currents. Typically, fumigants (gaseous pesticides) are most likely to drift.  When used, pesticides regularly spread further than the established application […]

(Beyond Pesticides, December 11, 2018) Meltwater and runoff from Alaskan glaciers contain detectable levels of organochlorine pesticides that bioconcentrate in fish and put individuals at risk, according to a new study from researchers at the University of Maine (UMaine). DDT, lindane, and other organochlorines have been detected throughout the world, even in natural areas thought to be untouched, and pristine. As UMaine scientists show, the atmospheric transport and ubiquitous deposition of these pesticides continues to pose risks to U.S. residents long after regulations banned their use. Although most of the highly toxic class of organochlorine pesticides like DDT were banned in the early 1970s, some chemicals retained certain uses. Lindane, for example, had its pest management uses phased out gradually until 2007, but is still allowed today as a scabies and lice shampoo. While use of these pesticides has declined in the U.S., much of the developing world, including many Asian countries, such as China, India, and North Korea, still report use. This results in atmospheric transport of the pesticides, and relevant to the UMaine research, increases the likelihood that the chemicals will eventually be deposited onto Alaskan glaciers through snow or rain. The UMaine research team investigated the amount of […]
