(Beyond Pesticides, December 18, 2015) One of the most likely causes for the population decline of smallmouth bass in the Susquehanna River are endocrine-disrupting compounds and herbicides, concludes a multi-agency, multi-year study of one of the most complex river systems in Pennsylvania. The Pennsylvania Department of Environmental Protection (DEP) and the Pennsylvania Fish and Boat Commission (PFBC), along with nearly 50 participants and six partner agencies, released findings on Monday that narrow the likely causes from an initial field of 14 candidates to two. PFBC also found that pathogens and parasites are probable contributing factors. Following a smallmouth bass (SMB) population crash in 2005, and additional observed maladies, such as tumors and lesions on SMB, the team used ground-breaking monitoring strategies to collect more than 30,000 water quality records annually, along with review of existing research to isolate the possible causes keeping young-of-the-year (YOY) SMB from growing to adulthood. The study provides evidence to what Beyond Pesticides suspected back in May, when PFBC confirmed that a rare malignant tumor was found for the first time on a SMB caught by an angler back in the summer of 2014. Though the findings at the time did not point to a specific […]

(Beyond Pesticides, November 23, 2015) Commonly-used pesticides can impact aquatic species over multiple weeks, even when chemicals are no longer detectable in water nor  monitored by regulators, according to new research. The study, titled A long-term assessment of pesticide mixture effects on aquatic invertebrate communities,  published in the journal Environmental Toxicology and Chemistry, investigates the long-term effects on aquatic invertebrate communities of commonly-used insecticides: two pyrethroids (permethrin and lambda-cyhalothrin) and an organophosphate (chlorpyrifos). Pesticide applications were based on environmentally relevant concentrations and lethal concentrations (a concentration required to kill a certain percentage of animals tested) ranging from 10% (LC10) to 50% (LC50). Researchers made repeat applications in order to mimic runoff events in a multiple grower or homeowner watershed. The results indicate that insecticide mixtures continue to impact natural systems over multiple weeks, even when bound to particles and no longer detectable in water. Combinations of indirect and direct effects caused consequences across the food chain. Pyrethroids rapidly dissipated from the water column, whereas chlorpyrifos was detectable even six weeks after application. “The effects we observed indicate that many species were affected at a sublethal level,” said Simone Hasenbein, Ph.D., lead author of the study tells Phys.org. “Thus, populations exposed […]

(Beyond Pesticides, November 09, 2015) The U.S. Department of Agriculture (USDA) cancelled a webinar on the presence of neonicotinoids in waterways in the Prairie Pothole region, according to the government watchdog group Public Employees for Environmental Responsibility (PEER). PEER states that the cancellation is “another example of USDA interfering with the release of new science-based information about adverse effects linked to  neonicotinoid (neonics) pesticides.” As a result, PEER continues, “Growing ecological risks posed by the most widely used insecticides in North America will likely not be considered in developing USDA policies, planning or management practices.” Neonicotinoids are a controversial class of chemicals that have been linked to the global bee decline by a rapidly growing body of scientific literature. A webinar, titled Pesticides and Potholes: Understanding the Risks of Neonicotinoid Insecticides to Aquatic Ecosystems in Prairie Canada and Beyond,  was supposed to take place June 24, 2014, according to PEER. Instead, the online event was cancelled by Wayne Honeycutt, Ph.D., the Deputy Chief for Science and Technology at USDA’s Natural Resources Conservation Service (NRCS). The online event would have featured Christy Morrissey, Ph.D., an assistant professor in the University of Saskatchewan, Saskatoon, School of Environment and Sustainability, whose research includes […]

(Beyond Pesticides, September 28, 2015) On September 4, in an attempt to curb the overuse of water on lawns, Governor Jerry Brown of California signed into law Bill (AB 349)  (effective immediately), which prohibits homeowner associations (HOAs) from barring the installation of synthetic turf. Artificial turf has become popular over the years, and is now widely used on athletic fields and lawns across the U.S. While praised as a solution for drought-stricken states, synthetic turf has fallen under scrutiny.  A NBC investigative report raised safety concerns regarding rubber infill in the turf. Parents and administrators are looking for alternatives to replace rubber infill beneath the turf, but unfortunately the available solutions do not address all the dangers associated with artificial turf. With all forms of synthetic turf, toxic pesticides and antimicrobials are still needed for maintenance, putting children and athletes in danger. Crumb rubber, the most common infill material used in synthetic turf systems, has, according to a recent report by Environment and Human Health, Inc., carcinogenic potential and poses a danger to the health of children and athletes. Now, parents and administrators are turning to organic infill as a replacement, which consists of coconut husks, fibers and cork. While […]

(Beyond Pesticides, September 1, 2015) A  research study published in the journal Environmental Health  links chronic, ultra-low dose exposure to glyphosate in drinking water to adverse impacts on the health of liver and kidneys. The study, Transcriptome profile analysis reflects rat liver and kidney damage following chronic ultra-low dose Roundup exposure, is the latest in a string of data showing unacceptable risks resulting from exposure to glyphosate and products formulated with the chemical, like Monsanto’s Roundup. Researchers conducted the study by exposing rats to minute (0.1 parts per billion) doses of Roundup in drinking water for a period of 2 years. After noting tissue damage and biochemical changes in the blood and urine of exposed animals that was indicative of organ damage, the authors attempted to confirm their findings by analyzing changes in gene expression within liver and kidneys. Of 4,447 gene transcript clusters analyzed by scientists, 4,224 showed some alteration. Compared to non-exposed rats, “[t]here were more than 4,000 genes in the liver and kidneys whose levels of expression had changed,” said Michael Antoniou, PhD, senior author of the study to Environmental Health News. Authors indicate that the changes in gene expression observed in the study are associated with […]

(Beyond Pesticides, August 31, 2015) A study published in Environmental Science and Technology, funded in part by the U.S. Geological Survey (USGS), has found that almost 2 million people are living near aquifer sites contaminated with uranium that is mobilized by human-contributed nitrate. Nitrate is a common groundwater contaminant that is sourced mainly from chemical fertilizers and animal waste. Chronic exposure to elevated levels of uranium can lead to kidney damage and cancer. These findings emphasize the dangers of synthetic fertilizer overuse, and highlight the need to switch to safer alternatives. The study, “Natural Uranium Contamination in Major U.S. Aquifers Linked to Nitrate,” analyzed approximately 275,000 groundwater samples from the Great Plains regions and California, finding that many residents often live less than a mile from uranium-contaminated wells that exceed guidelines set by the Environmental Protection Agency (EPA). In the High Plains aquifer, researchers find uranium concentrations up to 89 times EPA standards, while the Central Valley aquifer measure up to 180 times EPA standards. The study also reports that 78% of these uranium-contaminated sites are linked with the presence of nitrates. Nitrate mobilizes naturally occurring uranium through a series of reactions that oxidize the material, making it water soluble. […]

(Beyond Pesticides, July 27, 2015) Two Michigan Representatives have introduced the Great Lakes Assurance Program Verification Act (HR 3120) in an effort to halt the pollution of the Great Lakes and other waterways by protecting them from agricultural run-off, which causes dangerous algae blooms ­. While the proposed legislation aims to reduce the effects of pesticides in water, the bill still allows the use of toxic pesticides and fertilizers, and is only a voluntary measure, something that environmentalists says falls short. The bill is sponsored by Candice Miller (R-MI) and co-sponsored by Tim Walberg (R-MI). The bill aims to mimic the state program Michigan Agriculture Environmental Assurance Program (MAEAP). Adopted in 1999, the MAEAP is a voluntary three-phase program that provides “on-farm verification to ensure the farmer has implemented environmentally sound practices.” This raises two concerns: lack of incentive for farmers to join the program and ambiguous language defining what environmentally sound means. The results of MAEAP are the driving force in the fight for federal Great Lakes legislation, but those numbers do not necessarily speak for themselves. A major goal of the MAEAP is the Farmstead System which, “focuses primarily on protecting surface and ground water” through the safe […]

(Beyond Pesticides, June 05, 2015) A new federal bill was introduced Wednesday that, if passed, would undermine the U.S. Environmental Protection Agency’s (EPA) authority to issue Clean Water Act permits for pesticide spraying over waterways. Titled the Sensible Environmental Protection Act  and introduced by Senators Mike Crapo (R-Idaho) and Claire McCaskill (D-Mo), this new bill would reverse a 2009 federal court decision in National Cotton Council v. EPA that directed EPA to require permits from applicators who spray over “navigable waters,” as outlined in the Clean Water Act (CWA). The bill’s authors claim that the need for water permits is duplicative, given that pesticide applicators also comply with the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), the law that requires applicators to follow instructions on pesticide labels. “This issue is a prime example of an unnecessary, duplicative federal regulation impacting a variety of stakeholders in Idaho and across the nation that must be fixed,” Senator Crapo said in a statement.  “Our rural communities are already under a substantial amount of financial strain and regulatory pressure and are looking to Congress for much-needed relief.” Contrary to  Senator  Crapo’s claims, the  CWA permit serves as a valuable tool that lets authorities know […]

(Beyond Pesticides, May 11, 2015) Oil giant Chevron has been helping farmers in Kern County, CA find a solution to raising crops during the ongoing drought — but it may cause long-term health effects. The county is using treated oil field wastewater from the corporation to irrigate crops. As of now, the government only requires limited testing of treated wastewater, checking for naturally occurring toxins rather than screening for chemicals used in current oil-extraction processes. Legislation was passed last year that  requires oil companies to identify for  the state the chemicals they use in the oil-extraction process, but the Central Valley water authority, which regulates the water recycling program, gave producers until June 15 to report their results. To pick up the slack in the meantime, the advocacy group Water Defense, founded by actor and environmental activist Mark Ruffalo, collected samples of the treated irrigation water. The group works to promote access to clean water by testing local supplies and documenting contamination, and their findings indicated extremely high levels of oil, acetone and methylene chloride, a potential carcinogen, in the treated irrigation water. Beyond Pesticides has investigated treated wastewater from homes and residential areas. This research indicates that treated wastewater […]

(Beyond Pesticides, May 7, 2015) The Pennsylvania Fish and Boat Commission (PFBC) has confirmed that a rare malignant tumor was found on a smallmouth bass caught in the Susquehanna River by an angler late last summer. The finding was confirmed by two independent laboratory tests, including the U.S. Fish and Wildlife Service (FWS) and the Aquatic Animal Health Laboratory at Michigan State University.  Although it only represents one individual fish from the overall population, it provides additional evidence —which includes the prevalence of intersex fish discovered last summer”” that the health of the fish community residing in the river is being compromised, according to PFBC executive director John Arway. Though the findings do not point to a specific cause for the cancer found on the smallmouth bass (SMB), agricultural pesticides, particularly endocrine disrupting chemicals, that have been found in the watershed, likely play a part in the rampant disease issues in SMB in the Susquehanna River. “As we continue to study the river, we find young-of-year and now adult bass with sores, lesions and more recently a cancerous tumor, all of which continue to negatively impact population levels and recreational fishing,” Mr. Arway said. “The weight-of-evidence continues to build a […]

(Beyond Pesticides, April 29, 2015) Much to the dismay of activists and concerned local residents, the Washington Department of Ecology (Ecology) approved a permit for the use of imidacloprid (a neonicotinoid) to combat a growing native population of burrowing shrimp that threatens valuable shellfish (oyster) beds in Willapa Bay and Grays Harbor in Washington state. Imidacloprid is known to be toxic to bees but is also toxic to aquatic organisms, raising questions on the impacts of its use on the long-term ecological health of the bays. The shellfish industry is important to the Pacific Northwest, injecting an estimated $270 million or more into the region’s economy, and providing jobs for many. Washington’s tidelands, especially those in Willapa Bay, have been particularly productive for more than 100 years. However, according to shellfish growers, the burrowing shrimp (ghost shrimp, Neotrypaea californiensis,  and mud shrimp, Upogebia pugettensis) undermines the industry. The creatures burrow into shellfish beds, making the beds too soft for shellfish cultivation. Their burrowing churns the tidelands into a sticky muck, smothering the oysters. After several years of deliberations and studies, Ecology identified imidacloprid as its  preferred choice for eradicating the shrimp. According to the agency, imidacloprid disrupts the burrowing shrimps’ […]

(Beyond Pesticides, April 16, 2015) According to a new study, regulatory limits for insecticides are exceeded in over half of contaminated water samples collected from around the world. The study was based on a review of more than 800 studies conducted in 73 countries over the past five decades and is the first to evaluate the exposure of surface waters to particularly toxic agricultural insecticides on a global scale. Based on these results, the researchers ultimately conclude that “fundamental revisions of current regulatory procedures and pesticide application practices are needed to reverse the global environmental impacts of agro-chemical based high-intensity agriculture.” The analysis, published in the Proceedings of the National Academy of Sciences and titled “Agricultural insecticides threaten surface waters at the global scale,” was led by Sebastian Stehle, Ph.D., and Ralf Schulz, Ph.D, at the Institute for Environmental Sciences at University Koblenz-Landau in Germany. The researchers looked at 28 insecticides, the majority of which are currently approved in the United States and the European Union, represent all major insecticide classes, and are important for global agriculture in terms of annual application rates. While they found that just 2.6 percent of the 2,500 aquatic sites contained measurable levels of insecticides, […]

(Beyond Pesticides, March 24, 2015) Last week, to the dismay of health and environmental advocates, the House Agriculture Committee unanimously passed the latest version of the inaccurately titled “Reducing Regulatory Burdens Act of 2015” (H.R. 897), which would nullify regulations that require pesticide applicators to apply for National Pollutant Discharge Elimination System (NPDES) permits under the Clean Water Act (CWA) before applying pesticides on or near surface waters. The legislation also amends the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) by stating that no permit shall be required for the use of a pesticide that is registered under FIFRA. Generally, it means that pesticide applicators can discharge pesticides into waterways with no EPA oversight under the the standards of the CWA and the permitting process, which takes into account local conditions that are not addressed under FIFRA. The  CWA permit lets authorities know what is sprayed and when it is sprayed, so that the public may know what chemicals are used in their waterways and the potential dangers to sensitive aquatic ecosystems. Existing pesticide regulations under FIFRA do not achieve these protections and, contrary to the assertions made by supporters of the bill, most agricultural pesticide applications are exempt from […]

(Beyond Pesticides, February 20, 2015) A broad-based coalition is urging Canada’s Prime Minister Stephen Harper to put a stop to proposed changes to federal aquaculture regulations, citing damage to the environment and existing businesses. The proposed amendments to the federal Fisheries Act would exempt the aquaculture industry from provisions that “prohibit the release of deleterious substances into water frequented by fish.” Coalition members are worried that the changes will result in pesticides routinely being dumped into the Bay of Fundy,  located between the Canadian provinces of Nova Scotia and New Brunswick, and remove Environment Canada’s role in aquaculture activities, said spokeswoman Maria Recchia, the executive director of the Fundy North Fishermen’s Association. Aquaculture, which refers to the breeding, rearing, and harvesting of aquatic organisms such as fish, shellfish, and plants, provides half of the world’s seafood. According to  Food and Water Watch, offshore aquaculture follows an industrial agriculture model which grows thousands of animals in a confined environment. For fish, however, this confined space is in the ocean, meaning all of the waste products from the operation flow directly into the ocean. This includes excess feed and chemicals that are used, such as antibiotics and pesticides, to treat or prevent […]

(Beyond Pesticides, January 7, 2015) On Monday, the U.S. Environmental Protection Agency (EPA) released a revised human health assessment for the insecticide, chlorpyrifos, which finds risks to workers who mix, load and apply chlorpyrifos, and that the chemical has the potential to pose risks to drinking water in small watersheds. The assessment also notes that EPA will retain the 10X (10-fold) safety factor to protect children from all routes of exposures. EPA’s latest finding confirms long-standing scientific data that  has documented chlorpyrifos’ toxicity to humans and environmental contamination. However, despite these findings, EPA proposes to place additional restrictions on chlorpyrifos’ use, instead of a widespread ban. This latest assessment updates the June 2011 preliminary human health risk assessment, which was widely criticized by environmental and farmworker groups. EPA is releasing this assessment based on new information received since 2011, including public comments. The assessment is, in part, in response to a petition submitted by Natural Resources Defense Council (NRDC) and Pesticide Action Network (PAN) in 2007, which called on the agency to ban all uses of the insecticide. In 2000, EPA orchestrated a voluntary cancellation with the manufacturer Dow AgroSciences of  most residential uses of chlorpyrifos to limit children’s exposure, […]

(Beyond Pesticides, September 23, 2014) A new study finds that the increasingly common use of treated wastewater on food crops can result in contamination from chemicals like DEET, triclosan, and pharmaceutical drugs. The study, titled “Treated Wastewater Irrigation: Uptake of Pharmaceutical and Personal Care Products by Common Vegetables under Field Conditions” and published in Environmental Science & Technology,  measures levels of 19 commonly occurring pharmaceutical and personal care products (PPCPs) in eight  types of vegetables irrigated with treated wastewater under field conditions. The analytes studied include compounds that are commonly detected in treated wastewater, including 16 pharmaceuticals (acetaminophen, caffeine, meprobamate, atenolol, trimethoprim, carbamazepine, diazepam, gemfibrozil, and primidone) and three  personal care products (DEET, triclosan, and triclocarban). The vegetable species included in the  study are carrot, celery, lettuce, spinach, cabbage, cucumber, bell pepper, and tomato, which were included because they are often consumed raw by people and are also among the most important cash crops in arid and semi-arid regions, such as southern California, where there has been a rapid increase in irrigation with treated wastewater. The study points to water shortages in many parts of the world and the U.S. as factors contributing to the increase in use of recycled […]

(Beyond Pesticides, September 12, 2014) A new U.S. Geological Survey (USGS) report finds that levels of pesticides continue to be a concern for aquatic life in many of the Nation’s rivers and streams in agricultural and urban areas. The study, which documents pesticide levels in U.S. waterways for two decades (1992-2011), finds pesticides and their breakdown products in U.S. streams more than 90 percent of the time. Known pesticide water contaminants, such as atrazine, metolachlor, and simazine, continue to be detected in streams more than 50 percent of the time, with fipronil being the pesticide most frequently found at levels of potential concern for aquatic organisms in urban streams. According to the USGS report, “An Overview Comparing Results from Two Decades of Monitoring for Pesticides in the Nation’s Streams and Rivers, 1992—2001 and 2002—2011,” featured in the journal, Environmental Science and Technology and part of the agency’s ongoing National Water-Quality Assessment Program, the proportion of streams with one or more pesticides that exceed an aquatic-life benchmark (or guideline) is similar between the two decades for streams and rivers draining agricultural and mixed-land use areas, but much greater during the 2002-2011 for streams draining urban areas. During both decades, one or […]

(Beyond Pesticides, August 22, 2014) The Town Board in Wheatfield, New York unanimously voted last month to amend its biosolids law to ban any application of sewage sludge and other similar materials from the treatment of municipal wastewater to any land in town, even for those who already have permits from the state. The law reasons that the potential contamination of groundwater, surface water, and soil, as well as the potential for air pollution, poses an unreasonable risk to town residents, public health, and the environment. Biosolids, otherwise known as sewage sludge, are composed of dried microbes previously used to process wastewater in treatment plants. The material is increasingly being used in conventional agriculture, but its application is explicitly forbidden in organic production. This is because the sludge can contain high concentrations of toxic contaminants, such as pesticides, detergents, estrogenic hormones, antibiotics, dioxins, PCBs, flame retardants, and heavy metals. A 2002 study revealed the material to be associated with an increased prevalence of Staphylococcus aureus infections, a condition known to cause skin rashes and respiratory problems, for people located in close proximity to biosolid application sites. More recently, new research adds to existing evidence of the hazards of sewage sludge […]

(Beyond Pesticides, August 18, 2014) In a victory for environmental groups, conservationists, and fishing groups, the U.S. Environmental Protection Agency (EPA) finalized a settlement last Wednesday to restore no-spray buffer zones around waterways to protect imperiled salmon and steelhead from five toxic pesticides.   An initial agreement was reached in June, when it underwent public comment, and was ultimately filed August 13 without any substantive changes. The settlement follows litigation filed by Earthjustice, representing the Pacific Coast Federation of Fishermen’s Associations, the Northwest Coalition for Alternatives to Pesticides, and Defenders of Wildlife, back in 2010 that called for EPA adoption of reasonable fish protections from the insecticides. The buffers apply to salmon habitat throughout California, Oregon, and Washington to prohibit aerial spraying of broad-spectrum pesticides diazinon, chlorpyrifos, malathion, carbaryl, and methomyl within 300 feet of salmon habitat and prohibit ground-based applications within 60 feet. “Poisoning salmon rivers puts our people out of work while creating an unnecessary and expensive public health hazard,” said Glen Spain of the Pacific Coast Federation of Fishermen’s Associations, a West Coast commercial fishing industry trade association and co-plaintiff. “This agreement helps the coastal and inland communities that depend on salmon for their livelihoods and provides […]

(Beyond Pesticides, August 4, 2014) The Clean Water Act (CWA) provides critical safeguards for our nation’s waterways, with the goal of fishable and swimmable waters for all residents of the United States. Last Thursday, the House of Representatives voted to strip away an important part of these protections concerning pesticides applied directly to U.S. waters. The Reducing Regulatory Burdens Act of 2013 (HR 935) would reverse a 2009 ruling in National Cotton Council v. EPA that requires CWA permits for pesticide users who spray over waterways. After failing in a vote under a suspension of the rules last Monday, the House took the bill back up and passed it 267-161. “This is a good bill that reduces burdensome regulations without rolling back any environmental safeguards,” said U.S. Representative Bob Gibbs (R-OH), the bill’s sponsor, to The Hill. Unfortunately, Rep. Gibb’s statement couldn’t be farther from the truth. Under the deceptive title of “Reducing Regulatory Burdens,” this bill would instead eliminate critical CWA protections. “This legislation will undermine one of our nation’s most successful environmental laws, the Clean Water Act, in limiting the potential contamination of our nation’s waters by pesticides. All this would do is make it harder to locate […]

(Beyond Pesticides, July 31, 2014) Scientific researchers on opposite sides of the globe are coming to the same startling conclusion concerning very different species: what was once abundant is no longer and slipping away at drastic rates. Common Declines In the Pacific Northwest, a partnership of government scientists and environmental organizations have taken to the water to collect data on populations of certain species of marine birds. Unlike most research that  focuses on threatened or endangered species, however, this census targets birds like marbled murrelets, common murres, and long-tailed ducks ””thought to be commonplace and abundant. Thoughts have changed. Population counts from 2014 show these “common” species are in decline, and in several cases, steep decline. For example, population counts for the common loon have decreased from 1978/1979 by 64 percent, scoters by 77 percent, long-tailed ducks by 94 percent and western grebes by a scary 99 percent. Other species in general decline include the marbled murrelet, common murre, and glaucous-winged gull. On a different continent, the International Union for the Conservation of Nature (IUCN) conducted a wide swath of international scientific research and advocacy efforts targeting environmental and species monitoring and conservation. And much like the Pacific Northwest, recent […]

(Beyond Pesticides, July 25, 2014) A new U.S. Geological Survey (USGS) study published yesterday found neonicotinoid pesticides persistent and prevalent in streams throughout the Midwestern United States. The study is the first to investigate the presence of neonicotinoids on a wide-scale level in the Midwest. While neonicotinoid use has increased throughout the country, the Midwest in particular has seen a dramatic increase over the last decade. The use of clothianidin, one of the chemicals studied, on corn in Iowa alone has approximately doubled in just two years, from 2011 and 2013. Neonicotinoids are chemically similar to nicotine and are pesticides that are toxic to a broad range of insect pests. They are also known as systemic pesticides, which are pesticides that spread throughout the entire plant structure, making everything from roots to pollen toxic to organisms that come in contact with it. As a result, neonicotinoids have been linked to the global disappearance of honey bees and other nontarget organisms, such as earthworms, birds, and aquatic invertebrates. USGS scientist Kathryn Kuivila, Ph.D., stated, “Neonicotinoid insecticides are receiving increased attention by scientists as we explore the possible links between pesticides, nutrition, infectious disease, and other stress factors in the environment possibly […]

(Beyond Pesticides, July 21, 2014) According to figures released by the British Government last week, over 60% of the county’s bread supply is tainted with pesticide residues. This is a shocking increase from numbers recorded in 2001, which found 28% of bread to be tainted. According to the Department for Environment, Food and Rural Affairs (Defra) Expert Committee on Pesticides Residues in Food (PRIF), 2,951 bread samples were tested. According to a Pesticide Action Network UK report, a majority of the reoccurring pesticides were glyphosate and chlormequat. Glyphosate is an herbicide that can lead to non-Hodgkin’s Lymphoma, genetic damage, cancer, reproductive issues, liver damage, and endocrine disruption as well environmental damage such as water contamination and harmful effects to amphibians. Unfortunately, very little research has been done on what the effects can be on humans. Chlormequat, the second most-commonly found pesticide in British bread, is a plant growth regulator. A study conducted by the UN’s Food and Agriculture Organization (FAO) linked Chlormequat to developmental toxicity in animals. Very little research has been performed assessing the public health impact of this pesticide. In the U.S., it is only allowed for use on ornamental plants. Pan UK spokesman Nick Mole said, “The […]
