(Beyond Pesticides, October 8, 2024) A comprehensive literature review in Endocrines, published in September, amasses hundreds of studies on endocrine-disrupting chemicals (EDCs) that showcase adverse effects on growth, development, reproduction, and metabolism. The authors, a team of scientists and academics from Brazil, shed light on the link between EDC use and thyroid dysfunction, leading to increasingly prevalent illnesses and deadly diseases. Â Â Â EDCs are any synthetic or natural compounds that hinder endocrine system functions and create harmful effects on organisms. These chemicals can impact the thyroid gland, which is vital in producing hormones and plays a role in several body functions. As the researchers state, âSeveral EDCs have been classified as thyroid disruptors, impairing thyroid hormone [TH] production, synthesis, metabolism, transport, and/or actions. Notably, thyroid disorders are the second most prevalent endocrine disease worldwide, with incidence increasing significantly in recent years.â The authors continue, â[S]tudies have correlated this rise in thyroid dysfunctions and cancers with increased exposure to EDCs. Although many EDCs are linked to thyroid dysfunction, this review focuses on the deleterious effects of plasticizers, organochlorine pesticides, and per- and poly-fluoroalkyl substances on thyroid function. These contaminants are commonly found in food, water, and everyday products.â This review helps […]

(Beyond Pesticides, August 7, 2024) Using mass spectrometry techniques, researchers in Luxemburg and France detect 69 biomarkers of pollutants and pesticidesâ12 of which are bannedâin hair samples from over 200 French children. This study, published in Environment International, is the first to target over 150 biomarkers in a single hair sample, which ârepresents the most comprehensive assessment of chemical exposome in humans,â the authors say. All children in the study were 3.5 years old and recruited from the Ătude Longitudinale Française depuis lâEnfance (ELFE) [French Longitudinal Study since Childhood] cohort in the country of France, a major pesticide consumer in Europe. The ELFE survey is a joint project between the French Institute for Demographic Studies (INED) and the National Institute of Health and Medical Research (INSERM), which provides the first comprehensive national scientific investigation of children in France by following them from birth to adulthood. Through analysis of hair samples from children in the ELFE cohort, this study evaluates pesticide exposure and compares it with prenatal exposure data from their mothers while also, according to the scientists, âinvestigat[ing] the roles of childrenâs biological sex and geographical differences as possible determinants of exposure.â Exposure to pesticides during early childhood poses significant […]

(Beyond Pesticides, June 6, 2024) Researchers link pesticide exposure to behavioral effects on zebrafish (Danio rerio) larvae, signaling a larger issue for overall population and ecosystem effects. In a study published in Biomedicines, the authors conduct a multi-behavioral evaluation of the effects of three pesticides, both individually and as mixtures, on larvae. As the authors state, âEven at low concentrations, pesticides can negatively affect organisms, altering important behaviors that can have repercussions at the population level.â By analyzing effects on individual zebrafish with single compounds and mixtures, this study shows the dangers of pesticides in aquatic systems regarding synergy (a greater combined effect when substances mix) and the ripples created throughout entire ecosystems. Researchers from the Department of Morphology and Animal Physiology, as well as the Department of Physics, from the Rural Federal University of Pernambuco in Brazil collaborated with the Department of Biology at Indiana University in Indianapolis to perform the study. The researchers exposed zebrafish larvae to carbendazim, fipronil, and sulfentrazone to determine any behavioral effects on anxiety, fear, and spatial/social interaction for each compound separately and in combination. Each compound and mixture were applied to embryo medium, exposing fertilized zebrafish eggs. The embryos of zebrafish hatch, or […]

(Beyond Pesticides, March 22, 2022) German cockroaches collected from U.S. residential homes have evolved resistance mechanisms so strong that many can consume ten times the pesticide required to kill a laboratory-susceptible strain and still not die. These are the findings of recent research published in the Journal of Economic Entomology, which focused on determining cockroach resistance levels to commonly used gel bait insecticides in infested Southern California homes. The findings underscore the importance of an integrated approach to cockroach management that recognizes and responds to pest ecology, rather than search for an ever-elusive silver bullet. Researchers collected five different strains of German cockroaches from various locations around Southern California, two from public housing and three from apartment dwellers. All sites had long-standing cockroach infestations, with varying treatment histories that generally included significant use of common gel bait insecticides. Tests were conducted on male cockroaches as they are gregarious foragers and thus more susceptible to baited food; it was indicated that if an insecticide cannot kill a male, it is highly unlikely to kill a juvenile or female roach. A separate group of cockroaches reared in the laboratory and never exposed to insecticides was used as a baseline for comparison. This […]

(Beyond Pesticides, January 18, 2021) A study published in Environmental Science & Technology adds to the growing body of scientific research verifying the use of silicone devices as an effective tool for biomonitoring and disease prognosis, finding widespread exposure to people and pets. Researchers can identify the presence of chemical contaminants among humans and their canine companions occupying similar spaces using silicone monitoring devices (e.g., wristbands, collars, etc.). Although scientists can gauge chemical contamination with silicone devices, anthropoid (human) diseases can take many years to develop, even after initial contaminant exposure. Identifying chronic human diseases from pollutants remains challenging as scientists lack a full understanding of mechanisms involved in chemical-driven diseases development. However, dogs develop comparable anthropomorphic (human-like) diseases (e.g., cancer, organ damage) from susceptibility to the same environmental contaminants, but at a much quicker pace. Therefore, this research highlights the significance of identifying chemicals associated with diseases that are common across multiple species over longer disease latency periods. The researchers note, âThese results, in combination with our recent study investigating uptake rates of chemicals on wristbands, demonstrate that silicone samplers can be used to assess average integrated exposure over time (in this case over a week of exposure). Studies such as […]

(Beyond Pesticides, July 13, 2021) Bumblebees exposed to pesticides and pathogens display changes in gene expression that can be pinpointed and analyzed by cutting edge research tools, according to scientists at York university, who utilized the new technique in a study published in Molecular Ecology. This form of next-generation gene sequencing is part of a growing field of science known as conservation genomics, in which entire animal genomes are sequenced to determine conservation problems. âNext-generation sequencing is a totally new way to think about why bees are declining, which could revolutionize conservation biology,â says study coauthor Amro Zayed, PhD, associate professor in biology at York. âWeâre looking directly at bee tissues to try and get clues to the stressors that are affecting this bee. I think this is a gamechanger for sure. With a single study, we are able to implicate a couple of really obvious things weâve talked about for years â pathogens and pesticides â in the case of Bombus terricola.â Researchers focused on Bombus terricola â the yellow banded bumblebee, as its range has declined significantly over the last two decades. The bumblebee was once common throughout the eastern and midwestern part of the U.S. and Canada, […]

(Beyond Pesticides, June 23, 2021) Small streams are prone to excessively high levels of pesticide contamination that are even more hazardous than once thought, according to a pilot study generated by a team of German researchers. The results indicate significant risks for the health of aquatic ecosystems and should be used as evidence for establishing greater protections from toxic pesticide use, researchers say. With many aquatic benchmarks set by the U.S. Environmental Protection Agency lower than those established in Germany and the European Union, and evidence of widespread pesticide contamination in Americaâs waterways, the study could have even greater weight for for U.S. regulatory agencies’ deficiencies. Scientists established monitoring sites at more than 100 streams throughout Germany over the course of two years. Most sites were established near farm fields, where chemical farmers will use highly toxic pesticides than often make their way into local waterways. Streams were monitored for pesticide concentrations, with particular eye to whether they met the countryâs regulatory acceptable concentration (RAC value) in a given water body. The RAC value is intended to be the highest level at which there will be no adverse effects on aquatic life, however these regulatory levels often do not correspond […]

(Beyond Pesticides, November 20, 2020)Â Many pet owners likely do not consider what is actually in the flea treatments they administer to their animals. That should change, and recent research demonstrates why. Scientists sampling rivers in England found extreme contamination with two neurotoxic pesticides commonly used in flea products for dogs and cats: fipronil and the neonicotinoid imidacloprid. In many instances, the concentrations in the waterways were far higher than accepted âsafeâ levels. Though these compounds are banned for agricultural uses in the United Kingdom (UK), risk assessment for them, as used on animals, has been minimal because of the assumption that the amounts used for veterinary treatments would mean far-less-significant environmental impact than might be expected with agricultural-scale use. This research out of the University of Sussex voids that assumption, and the researchers recommend âre-evaluation of the environmental risks posed by pet parasite products, and a reappraisal of the risk assessments that these products undergo prior to regulatory approval.â Apart from being an active ingredient in flea treatments for pets, fipronil is used in insect baits, and in turf management and agriculture in the U.S. It is highly toxic to insects, including bees, to birds, and to aquatic invertebrates.

(Beyond Pesticides, October 27, 2020) The insecticide fipronil is more toxic to aquatic insects than previously thought, often present in U.S. waterways, and can trigger trophic cascades that disrupt entire aquatic ecosystems, finds new research published by the U.S. Geological  Survey (USGS). The data have important implications for waterways throughout the country, but particularly in the Southeast U.S. where the chemical was found at hazardous levels in over half of sampled steams. Despite the high quality of the findings by a U.S. government agency, pesticide regulators at the U.S. Environmental Protection Agency (EPA) do not adequately consider ecosystem-level effects when determining whether to register a pesticide. As a result, without public pressure on the agency, it is unlikely it will follow the science and take the action necessary to rein in use and safeguard the environment. Fipronil is a systemic pesticide that can travel through plant tissues and be expressed in its pollen, nectar, and dew droplets. Due to its systemic properties and similar toxicity profile, it is often targeted for restriction alongside the notorious neonicotinoid class of insecticides. Although fipronil is equally concerning, there is less data on the range of harm the chemical may cause. To better understand […]

(Beyond Pesticides, June 15, 2020) A dog owner in southern Florida is warning other owners about the safety of flea and tick medication after his dog suffered a seizure and lost mobility in her back legs. As reported by CBS WINK, owner Joe Brewster switched to the product PetArmor Plus for Dogs, manufactured by Sergeant’s Pet Care Products, Inc., just three days before his dog, Buddha, suffered a seizure. âThey asked me if I changed flea and tick medication,â Mr. Brewster told WINK news. âAnd I thought for a minute, and I go, âYeah, three days before.ââ Although the type of event experienced by Buddha was characterized by veterinarians and the U.S. Environmental Protection Agency (EPA) as rare, the onset of neurological problems is a serious issue that could be indicative of future health impacts on pet owners. According to a recent study, dogs can act as sentinel species for chemical-induced human diseases. Wendy Mandese, PhD, a veterinarian and professor at the University of Florida told reporters, âWe may see an animal that has an issue one or two times a year.â However, EPA told WINK news that over the last decade, it received over 1,300 reports of pesticide incidents involving […]

(Beyond Pesticides, March 4, 2019) Last week, U.S. Representative Earl Blumenauer (D-OR) reintroduced the Saving Americaâs Pollinators Act (H.R.1337) to cancel specific bee-toxic pesticides and establish a review and cancellation process for all pesticides that are potentially harmful to pollinators. The specific pesticides targeted in the bill include the systemic insecticides imidacloprid, clothianidin, thiamethoxam, dinotefuran, acetamiprid, sulfoxaflor, flupyradifurone, and fipronil. The bill also establishes requirements for review of other potentially bee-toxic chemicals by an independent pollinator protection board, and requires annual reports on the health and population status of pollinators. The bill creates a sustainable model for pollinator protection in the face of ongoing obstruction by an increasingly industry-influenced EPA. There are 29 cosponsors to date. The current bill is the fifth version of Saving America’s Pollinators Act (SAPA), which was first introduced by U.S. Representative Conyers (D-MI) in 2013. The newest version differs from previous bills in its bold definition of who should have responsibility for assessing harm to pollinators. SAPA 2019 calls for the establishment of a Pollinator Protection Board, to be composed of expert scientists, beekeepers, farmers, members of environmental organizations and other key stakeholders, nearly all of whom must not have any conflict of interest or affiliation […]

EU(Beyond Pesticides, August 16, 2017) Millions of eggs and egg products have been pulled from supermarket shelves in 15 countries in Europe after it was discovered that the eggs were contaminated with the insecticide fipronil. Now,  the European Commissioner in charge of food safety has called for a meeting of ministers and national regulatory agencies to discuss the widespread European contamination. However, fipronil is not allowed for use in food production in Europe, raising concerns over food safety and regulatory oversight. This incident reminds U.S. consumers about the disarray of the U.S. food safety system, as reported by the U.S. Government Accountability Office (GAO) in 2014. According to the GAO report, Food Safety: FDA and USDA Should Strengthen Pesticide Residue Monitoring Programs and Further Disclose Monitoring Limitations, there is a lack of government coordination on food safety and the U.S. Food and Drug Administration (FDA) does not test food for several commonly used pesticides with established tolerance levels. The report sounds an alarm that GAO began sounding  in the 1980âs in several reports that identify shocking limitations of  FDAâs approach to monitoring for pesticide residue violations in food. (See Beyond Pesticides’ coverage.) Since that report, FDA announced, then withdrew its announcement, […]

(Beyond Pesticides, April 4, 2016) Pesticides widely used in rice paddies in Japan are harming  dragonflies. The study, conducted by researchers at Japanâs National Institute for Environmental Studies, finds that the insecticide fipronil significantly reduces the population of adult dragonflies, more so than any other pesticide treatment. The study, titled Fipronil application on rice paddy fields reduces densities of common skimmer and scarlet skimmer  and published in the journal Scientific Reports, investigated the impact of neonicotinoids, which have been linked to bee die-offs around the world, and chlorantraniliprole, which, like neonicotinoids and fipronil, is a systemic pesticide that is taken up by the plant and subsequently expressed in pollen, nectar, and guttation droplets. Plankton species were adversely  affected by clothianidin, a neonicotinoid, and chlorantraniliprole, but they recovered after concentrations of the chemicals decreased. Koichi Goka, Ph.D., a senior researcher at the institute, said nymphs living near the soil are particularly vulnerable to toxic chemicals, according to The Asahi Shimbun. âThe density of insecticidal components in the water drops quickly after they are dissolved,â Goka said. âBut such components long remain in the soil. Nymphs at the bottom of water could have been affected.â Dr. Goka is calling for more testing […]

 (Beyond Pesticides, January 20, 2016) Aldi SĂźd, the German supermarket chain with stores in the U.S., has become the first major European retailer to ban pesticides toxic to bees, including the neonicotinoids imidacloprid, clothianidin and thiamethoxam, from fruits and vegetables produced for their stores. Aldi has requested suppliers comply at the earliest possible time. In light of the growing pollinator crisis and due to public pressure, retailers in Europe and the U.S. are slowly beginning to make the switch away from bee-toxic pesticides. Beginning January 1, suppliers of fruits and vegetables to Aldi suppliers will have to ensure that their cultivation practices do not include the following eight pesticides identified as toxic to bees (thiamethoxam, chlorpyrifos,  clothianidin, cypermethrin, deltamethrin, fipronil, imidacloprid and sulfoxaflor) to meet  the new requirement. According to a press release from Greenpeace, the chemicals are used on various commodities in Europe  —thiamethoxam (used in lettuce and endive), chlorpyrifos, clothianidin (used in kohlrabi, herbs, Brussels sprouts, head cabbage, cauliflower and kale), cypermethrin (leek, head cabbage and leguminous vegetables), deltamethrin (cauliflower, peppers, eggplant, zucchini, cucumber, pea, head cabbage, tomato and lettuce),  imidacloprid (applied to apples, peaches, apricots and lettuce). Sulfoxaflor was recently granted regulatory approval in Europe, despite calls […]

(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, 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 âfundamental 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, 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 Nationâs 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, âAn Overview Comparing Results from Two Decades of Monitoring for Pesticides in the Nationâs Streams and Rivers, 1992â2001 and 2002â2011,â featured in the journal, Environmental Science and Technology and part of the agencyâs 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, September 3, 2014) The U.S. Justice Department sentenced Steven A. Murray, a pesticide operator with Bio-Tech Management in Pelham, Georgia, to two years in prison last week after as a result of charges related to a cover up illegal pesticide applications made at over 100 nursing homes. Mr. Murray pleaded guilty to one count of conspiracy, three counts of false statements, two counts of mail fraud, and 10 counts of unlawful use of a registered pesticide. In addition to being sentenced to two years in prison, Murray was subject to a $7,500 fine. His company was placed on three years of probation and also required to pay a $50,000 fine. From October 2005 to June 2009, Mr. Murray and Bio-Tech provided monthly pest control services to hundreds of nursing homes in several southern states including Georgia, South Carolina, North Carolina and Alabama by spraying pesticides in and around their clientsâ facilities. Bio-Tech employees routinely  applied  the pesticide Termidor indoors, contrary to the  manufacturerâs  label  instructions, and then created false service reports to conceal that illegal use. After the Georgia Department of Agriculture made inquiries regarding Bio-Techâs illegal use of Termidor and other pesticides, Mr. Murray directed several of […]

(Beyond Pesticides, August 22, 2014) In a blow to the adoption of urgently needed protections for pollinators, the California State Senate voted 35-1, after an earlier Assembly vote of 75-0,  to delay a requirement for action on bee-harming neonicotinoid (neonic) pesticides until 2020. While advocates want mandates for  regulatory action to protect bees, the timeline in the bill ignores that ongoing crisis faced by bees, beekeepers, and agriculture dependent on bee pollination.  Assembly Bill 1789 provides the California Department of Pesticide Regulation (CalDPR) another four years to reevaluate neonicotinoid pesticides, and an additional two years to implement any measures that would be needed to protect pollinator health. Given that CalDPR began its reevaluation of neonics in 2009, and existing law would have required a complete reevaluation within two years, the legislatureâs new 2020 timeline has been met with strong criticism from beekeepers and environmental groups. The passage of AB 1789 sets the CalDPR on a track similar to the U.S. Environmental Protection Agencyâs (EPA) timeline for neonic review. This timeline is widely seen as an unacceptable response to the pollinator crisis, given unsustainable declines of greater than 30% of managed honey bee colonies each year, and widespread adverse impacts on […]

(Beyond Pesticides, June 25, 2014) Following last weekâs celebration of âNational Pollinator Weekâ and a presidential memorandum mandating federal action on bees, the first wide-scale scientific analysis has been released that links  two classes of pesticides  to declining bee populations. Twenty-nine scientists representing many disciplines reviewed over 800 peer-reviewed publications  on the impacts of systemic pesticides, and are recommending  more restrictions on neonicotinoid pesticides. This report is the single most comprehensive study of  neonicotinoids ever  undertaken. The âWorldwide Integrated Assessment (WIA)â ââ undertaken by the Task Force on Systemic Pesticides ââ documents significant harms to bees and ecosystems. While some aspects of this report have been broadly acknowledged  before (e.g. risks to honey bees), some, including risks to earthworms, birds and aquatic invertebrates, have not. The analysis focuses not only on impacts to particular  organisms and habitats, but also on  biodiversity and ecosystem impacts, taking a holistic view of pesticide effects. The scientists are calling for new, dramatic restrictions on bee-harming pesticides in the United States and beyond. The report  finds that the current regulatory system has failed to consider the full  range of pesticide effects. “This report should be a final wake up call for American regulators who have […]

(Beyond Pesticides, June 9, 2014) A recent talk given by Donald Weston, PhD, a professor emeritus in UC Berkeley’s Department of Integrative Biology, to a community group in San Jose, California warned residents about the dangers that  lawn care insecticides present to  local aquatic life. The talk focused on the problems synthetic pyrethroids and fipronil can have on Hyalella azteca and Chironomus dilutes. Increasing levels of pesticide runoff in local stream systems have not only led to decreased populations of these aquatic crustaceans, but also populations that have become resistant to pesticides. Aquatic invertebrates are extremely sensitive to pesticide runoff and different states around the country have struggled with creating pesticide regulations that foster a healthy aquatic ecosystem. A good way to reduce pesticide runoff is to transition away from toxic land care methods and adopt organic practices. Hyalella crustaceans, a tiny shrimp-like animal, are hypersensitive to pyrethroids, which are a class of insecticides used by professional lawn care companies and found in common products like Raid and mixed with fertilizer products like Scotts Turf Builder under the name SummerGuard. Chironomus dilutes, a red worm-like invertebrate, is sensitive to fipronil, which is used to kill fleas on dogs and cats […]

(Beyond Pesticides, May 28, 2014) A statewide pilot pesticide sampling project has found over 20 different types of pesticides in Hawaiian waterways, some of which are no longer registered for use in Hawaii. State officials believe the pesticides, many detected in urban areas, are from residential and golf course applications. These preliminary findings help highlight the need for local oversight of pesticide use, currently a controversial issue in the state. Conducted in partnership with the Hawaiian Department of Agriculture, the U.S. Geological Survey (USGS) and the Hawaiian Department of Health, the survey-study finds herbicides like glyphosate (Roundup) and atrazine, as well as a fungicide that is no longer registered for use in the state, contaminating the stateâs waterways. The study measured pesticides in surface waters and in sediment at multiple locations in Hawaii. 25 herbicides, 11 insecticides and 6 fungicides were detected, with atrazine the most commonly found. This pilot survey responds to growing community concerns about the impacts of pesticides on local communities and ecosystems, and provides preliminary information on pesticide residues in state waterways. Recently, Kauai County passed an ordinance âOrdinance 960â Â that requires public disclosure of pesticides used and the location of genetically engineered (GE) crops, as […]

(Beyond Pesticides, November 12, 2013) On November 6 BASF, a German agrochemical company, took legal action in the General Court of the European Union (EU) to challenge the EU Commissionâs decision to restrict seed treatment uses of the insecticide fipronil. BASF joins chemical companies Bayer and Syngenta in challenging the EUâs decision to restrict the use of certain pesticides that are harmful to pollinators. The EU Commissionâs decision to restrict the use of fipronil in July came after the Commissionâs landmark decision announcing a two-year continent-wide ban  on the neonicotinoid pesticides clothianidin, imidacloprid and thiamethoxam. The pesticides have been linked to the decline in bee populations.  Twenty-three European Union Member States supported the fipronil restriction, two Member States voted against, and three Member States abstained during the standing committee vote. BASF argued that its  legal action against the EU is based on a disproportionate application of the precautionary principle. However, overwhelming scientific evidence supports the position that fipronil is highly toxic to bees. Fipronil, a phenyl pyrazole broad-spectrum insecticide, was first introduced in the U.S. in 1996 for commercial turf and indoor pest control and is highly toxic to bees. A recent investigation reveals that fipronil is responsible for the […]
