EPA Releases Pyrethroid Risk Assessment, Ignores Numerous Health Effects

Wednesday, November 16th, 2011

(Beyond Pesticides, November 16, 2011) On November 9, 2011, the U.S. Environmental Protection Agency (EPA) issued its cumulative risk assessment for the pyrethroid class of insecticides, concluding that these pesticides “do not pose risk concerns for children or adults,” ignoring a wealth of independent data that links this class of chemicals to certain cancers, respiratory and reproductive problems, and the onset of insect resistance. The agency went as far to state that its cumulative assessment supports consideration of registering additional new uses of these pesticides, potentially opening the flood gates for manufacturers to bombard the market with more pyrethroid pesticides, endangering the health of the public. EPA issued the final pyrethins/pyrethroid cumulative risk assessment in the Federal Register and is requesting comment until January 9, 2011, including information that may be used to further refine the assessment. Pyrethroids are a widely used class of insecticides used for mosquito control and various insects in residential and agricultural settings. However pyrethroids are highly neurotoxic and have been linked to cancer, endocrine disruption, suppression of the immune system, and various reproductive effects. This class of chemicals includes permethrin, bifenthrin, resmethrin, cyfluthrin and scores of others. Read Beyond Pesticides’ factsheet “Syntethic Pyrethroids.” Once the […]

Group Files Lawsuit for Failure to Protect Red-Legged Frogs

Thursday, October 20th, 2011

(Beyond Pesticides, October 20, 2011) The Center for Biological Diversity filed a lawsuit yesterday against the Environmental Protection Agency (EPA) and U.S. Fish and Wildlife Service (FWS) for failing to evaluate and act on threats to the threatened California red-legged frog posed by more than 60 toxic pesticides used in and near its habitats. The Center had announced its intent to sue the two agencies back in December 2010. A 2006 legal settlement secured by the Center requires EPA to assess the impacts of harmful pesticides on red-legged frogs and formally consult with the Fish and Wildlife Service to address those impacts. EPA determined that widespread use of more than 60 pesticides is likely harming red-legged frogs, but since the agency and the Fish and Wildlife Service have failed to complete the required evaluations, no permanent protections for frogs have been put in place. “Federal agencies acknowledge that scores of pesticides may harm California’s rare red-legged frogs, but for years now they’ve neglected to complete biological evaluations of the effects of these chemicals,” said Jeff Miller, a conservation advocate with the Center. “California’s imperiled frogs are suffering as a result.” “Biological opinions,” the evaluations required by the Endangered Species Act, […]

White House Proposes Increased Pesticide Registration Fees

Thursday, September 22nd, 2011

(Beyond Pesticides, September 22, 2011) As part of his $3 trillion deficit-reduction plan, President Obama has proposed to increase pesticide and chemical registration fees and reinstate tolerance assessment fees in order to cover the costs of evaluating the chemicals’ health and environmental effects data. The U.S. Environmental Protection Agency (EPA) currently collects fees from companies seeking to register their pesticides or maintain existing registrations; however these fees do not cover the full cost of the review process. The White House fee collection proposal will save $740 million over 10 years. Under the reregistration program, pesticides that were registered prior to November 1, 1984 are evaluated to ensure that they continue to meet current regulatory standards. EPA began this effort under 1988 amendments to the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). The amendment also requires EPA to review all other registered pesticides on a 15-year cycle to ensure that registrations reflect current regulations. The reregistration of pesticides under FIFRA is a lengthy and ongoing process. Hundreds of pesticides currently registered and commonly used still lack a full assessment of their potential short and long-term effects on human health, particularly on children, and the environment. For example, EPA has failed to […]

White House Blocks EPA Chemical Health Review

Thursday, September 15th, 2011

(Beyond Pesticides, September 15, 2011) Bowing to pressure from the chemical industry, the administration of President Barack Obama recently blocked a new and desperately needed U.S. Environmental Protection Agency (EPA) review of chemical health hazards which was developed under the agency’s Integrated Risk Information System (IRIS), according to Daniel Rosenberg of the Natural Resources Defense Council. In his blog, Mr. Rosenberg reported on September 13 that, “[T]he White House worked behind the scenes to stop EPA from issuing a hazard assessment of the cancer-causing chemical TCE [produced through the IRIS program] — and is working to effectively shut down the EPA’s program for assessing the hazards of chemicals — the basis for setting and updating health standards for drinking water, air quality, and clean-up of contaminated soil.” He notes that the move was obscured as it fell on the same day as the widely reported and controversial decision by the administration to withdraw a new EPA health standard for ozone smog. A chemical health review under IRIS apparently provided the groundwork for the establishment of a new health standard for the carcinogenic trichloroethylene (TCE), but the findings yielded no action. The existing standard for the substance was last updated more […]

New Issues Arise Over Methyl Iodide Use

Wednesday, September 7th, 2011

(Beyond Pesticides, September 7, 2011) California’s approval of the dangerous and controversial agricultural chemical, methyl iodide, suffered serious questions with the release of new documents showing the fumigant’s registration process was flawed. The documents, which were made public as part of a lawsuit challenging the state’s approval of the chemical, show the state’s Department of Pesticide Regulation (DPR) cut and pasted calculations from different risk assessments in order to come up with a less stringent set of restrictions on the chemical’s use. Earlier this year, several environmental groups sued the State of California for approving the agricultural use of methyl iodide. Methyl iodide is known to cause miscarriages, thyroid dysfunction, and cancer, and is applied to crops like strawberries and peppers. It was approved by California state pesticide regulators in December as an alternative to methyl bromide, an ozone-depleting chemical being phased out under international treaty. Environmental advocacy groups and other opponents of methyl iodide use in the state have released documents detailing dissension in the ranks of DPR over the risk assessment of methyl iodide and its subsequent approval. Earthjustice, a nonprofit environmental law group, sued DPR in an attempt to reverse the state’s approval of the chemical. The […]

Voluntary Program Evaluating Children’s Toxic Exposure Flawed

Thursday, July 28th, 2011

(Beyond Pesticides, July 28, 2011) A new report released last week finds that the U.S. Environmental Protection Agency’s (EPA) voluntary program to evaluate chemicals fails to protect children. According to the evaluation report by EPA’s Inspector General, the Voluntary Children’s Chemical Evaluation Program (VCCEP) was hampered by industry’s refusal to voluntarily collect and submit information and the agency’s failure to regulate under the Toxic Substances Control Act (TSCA) to collect the data. The report states what environmental groups have known for years: “EPA has not demonstrated that it can achieve children’s health goals with a voluntary program.” According to the Inspector General (IG), these failures led to only a fraction of the chemical assessments for the pilot being completed. IG found that VCCEP’s pilot was critically flawed and that the design of the program “did not allow for the desired outcomes to be produced.” It had a flawed chemical selection process and lacked an effective communication strategy. VCCEP is no longer operational and EPA has no plans to revive, replace, or terminate the program. The program was set up as part of the Chemical Right-to-Know Initiative in 1998 to ensure that there are adequate publicly available data to assess the […]

Bill Reintroduced to Regulate Chemicals in Cosmetic Products

Wednesday, June 29th, 2011

(Beyond Pesticides, June 29, 2011) The Safe Cosmetics Act of 2011 was reintroduced last week in the House of Representatives aiming to grant the U.S. Food and Drug Administration (FDA) authority to regulate personal care products, including cosmetics, to ensure they are free of harmful ingredients before they hit the shelves. Cosmetics currently go unregulated and can contain harmful ingredients like triclosan, heavy metals, formaldehyde and others which expose consumers to numerous health threats. The cosmetic and personal care product industry is self-regulated. But the Safe Cosmetics Act of 2011 will, according to U.S. Representative Ed Markey, a lead sponsor on the bill, “close a gaping hole in the federal law that allows potentially toxic chemicals to remain in the cosmetics products consumers use every day. Reps. Jan Schakowsky of Illinois, Ed Markey of Massachusetts and Tammy Baldwin of Wisconsin offered the “Safe Cosmetics Act of 2011,” which would require companies to put all of a product’s ingredients on its label. It would also require the Department of Health and Human Services to conduct random annual tests of products for harmful substances and would force FDA to produce a list of ingredients that are prohibited from being used in cosmetics.

EPA May Reduce “Conditional Registrations” of Pesticides after Finding Process Flawed

Wednesday, May 4th, 2011

(Beyond Pesticides, May 4, 2011) According to a U.S. Environmental Protection Agency (EPA) internal review of pesticide registrations under special circumstances, also known as “conditional registration,” the agency may reduce its use of this “imprecise” category, whilch allows widespread use of toxic chemicals not fully tested. Conditional registration of pesticides allows market entry for a product in the absence of certain data. Recent reports have found that certain conditionally registered pesticides known to be hazardous to pollinators were allowed to used by EPA without a full data set. In an April 25, 2011 post on its website, EPA provides details on its recently completed internal review on the use of conditional registration for pesticide products. The agency has come under scrutiny recently since it was revealed that the conditionally registered pesticide, clothianidin, did not at the time it allowed the pesticide to be widely used have pertinent field data required on honeybees, even though the pesticide is known to pose risks to these vulnerable pollinators. This data is still outstanding even though clothianidin continues to be used in the environment. Conditional registration is allowed under Section 3(c)(7) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), whilch allows pesticide registration […]

EPA Seeks Advice in Reviewing the Impact of Pesticides on Endangered Species

Friday, March 18th, 2011

(Beyond Pesticides, March 18, 2011) As a result of recent court mandated consultations under the Endangered Species Act (ESA) concerning pacific salmon and steel head, the U.S. Environmental Protection Agency (EPA) in a letter to the National Research Council (NRC) is requesting the convening of a committee of independent experts to assist in the review of special scientific and technical issues that have arisen as the agency attempts to stem the impact of pesticides on these endangered species. Citing issues of scientific complexity and high importance, the letter authored by EPA Administrator Lisa Jackson, requests on behalf of the EPA, the Fish and Wildlife Service and the National Marine Fisheries Service (NMFS), a “concerted, closely coordinated effort” to address these issues openly and actively. NRC’s assistance is sought due to the number of complex scientific issues brought to the attention of the agencies as they complete consultations under the ESA concerning the impact of pesticides on endangered salmon and steelhead. Even though calls for EPA to holistically review pesticides have been made by scientists and the environmental community before, EPA is now seeking advice in assessing the effect of pesticides and other Federal Insecticide, Fungicide and Rodenticide Act (FIFRA)-related actions […]

Dow Seeks To Overturn EPA Ban of Toxic Fluoride-Based Pesticide

Tuesday, March 15th, 2011

(Beyond Pesticides, March 15, 2011) Following the U.S. Environmental Protection Agency’s (EPA) January 10th announcement that it plans to cancel all allowable pesticide residue levels (tolerances) of the toxic fumigant sulfuryl fluoride–effectively banning its use, the chemical’s manufacturer, Dow AgroSciences, is petitioning EPA to launch a formal registration cancellation hearing under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). EPA decided to cancel the tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA) after determining that when residues on food products are combined with fluoridated drinking water and toothpaste, public exposure levels are too high. The agency took the action in response to a June 2006 petition submitted by Fluoride Action Network, Beyond Pesticides, and Environmental Working Group. Food Quality Protection Act of 1996 (FQPA) amendments to FFDCA require that a pesticide registered for use by EPA cannot exceed acceptable risk thresholds when its dietary and nondietary uses are evaluated in the aggregate. Environmentalists believe that the January 2011 sulfuryl fluoride decision was the first time EPA action has resulted in a comprehensive pesticide cancellation of agricultural uses (as distinct from a voluntary cancellation by the manufacturer) because of unacceptable aggregate exposure. While cancellation hearings are not provided under […]

Indian Government Resists Ban on Endosulfan, A Chemical It Manufactures

Thursday, February 10th, 2011

(Beyond Pesticides, February 10, 2011) Despite the numerous scientific data on the devastating health and environmental consequences of endosulfan —a pesticide so toxic that is banned in over 60 countries including the U.S., officials in India say that a ban on the widely used chemical would put the country’s food security at risk and harm the welfare of farmers. However, thousands of villagers in Kerala, India, who have become disabled due to the use of the pesticide, pushed for a state ban in 2004 and have since joined the global movement to ban endosulfan. Doctors say that over 550 deaths and health problems in over 6,000 people in the region are related to the aerial spraying of the pesticide over cashew farms between 1979 and 2000. “Six thousand patients living with disabilities is not enough scientific evidence to enforce a national ban?,” asked B.C. Kumar, to the Washington Post. Kumar’s father, a cashew farm laborer, died of cancer. The endosulfan industry in India is estmiated to be worth over $100 million, making it the world’s largest producer, exporter and user of the product. The three companies that produce the product in India, including one that is partially government-owned, claim that […]

Study Links Prenatal Exposure to Pyrethroid Insecticides and Learning Problems

Tuesday, February 8th, 2011

(Beyond Pesticides, February 8, 2011) Research published February 7, 2011 in the online edition of the journal Peditatrics shows that children more highly exposed to pyrethroid insecticides and piperonyl butoxide (PBO), a synergist added to increase the potency of pyrethroids, are three times as likely to have a mental delay compared to children with lower levels. The study, “Impact of Prenatal Exposure to Piperonyl Butoxide and Permethrin on 36-Month Neurodevelopment,” measured exposure to pesticides using maternal and umbilical cord plasma samples and in personal air samples, collected using backpack air monitors during pregnancy. Children were then tested for cognitive and motor development (using the Bayley Scales of Infant Development) at three years of age. Children with the highest prenatal exposures scored about 4 points lower on the test. That’s about the same intelligence loss caused by lead, Philip Landrigan, MD, a pediatrics professor and environmental health expert at New York’s Mount Sinai School of Medicine, told USA Today. Pyrethroid pesticides kill bugs by “being toxic to the developing brain,” Dr. Landrigan says. The results are “very believable and should be taken seriously.” Pyrethroid pesticides have increased in popularity over the past decade due in large part to the phase-out of […]

EPA Responds to Petition, Proposes Elimination of Toxic Fumigant

Tuesday, January 11th, 2011

(Beyond Pesticides, January, 11, 2011) Responding to a June 2006 petition submitted by Fluoride Action Network, Beyond Pesticides, and Environmental Working Group, the U.S. Environmental Protection Agency (EPA) has announced that it proposes to eliminate the use of the toxic fumigant sulfuryl fluoride in agriculture and food related applications. The agency plans to cancel all allowable pesticide residue levels (tolerances) for the chemical, finding that, when residues on food products are combined with fluoridated drinking water and toothpaste, public exposure levels are too high. Under the Federal Food, Drug, and Cosmetic Act (FFDCA), EPA is required to ensure that pesticides it has registered for use cannot combine with non-food sources of the same substance to result in unsafe levels of exposure for that chemical. According to EPA officials, the decision appears to be the first time the agency has granted substantive formal objections to a pesticide tolerance rule based on public health advocates’ evidence that a particular chemical’s use violates the safety standard for aggregate exposures under federal law. Despite granting the petition’s assertion that total public exposure to fluoride is too high, EPA has denied the petition’s request for an immediate stay of all registered uses of sulfuryl fluoride.

Scientists Examine Chlorpyrifos Levels in Potatoes

Monday, December 20th, 2010

(Beyond Pesticides, December 20, 2010) A new study examines the residue levels of the organophosphate insecticide chlorpyrifos in Colombian potatoes, finding that residual levels of the pesticide are still present even after being cooked. According to researchers, the pesticide has a tendency to build up in the raw potatoes, but once they were cooked, the levels dropped by 14%, leaving a fraction of the allowable levels of chlorpyrifos in the potato, under European Union (EU) daily intake limits. While it may be true that there are relatively low residual levels of the pesticide found in the potato once it has been cooked, many adocates are concerned about the remaining residues. The study, entitled “Pesticide Uptake in Potatoes: Model and Field Experiments,” was published in the journal Environmental Science and Technology. The fact that there remains some residual chlorpyrifos in the cooked potatoes is a concern because studies show that even at low doses, in utero exposure can cause changes in brain function and altered thyroid levels that last into adulthood. Young children are particularly susceptible to the effects of exposure. Because children’s diets often include significant quantities of potatoes, this is particularly alarming in light of a recent study that […]

Group Plans to Sue Agencies over Threatened Amphibian

Thursday, December 16th, 2010

(Beyond Pesticides, December 16, 2010)The Center for Biological Diversity notified the U.S. Fish and Wildlife Service (USFWS) and U.S. Environmental Protection Agency (EPA) December 15 of its intent to sue the agencies for failing to study and act on threats posed by more than 60 pesticides to the threatened California red-legged frog. A 2006 legal settlement secured by the Center required the EPA to assess the impacts of pesticides on the frog, then consult with the U.S. Fish and Wildlife Service (USFWS) under the Endangered Species Act to address those impacts, by 2009. The completed assessments were submitted to the Wildlife Service between March 2007 and October 2009. Although EPA determined that 64 registered pesticides are likely to harm the frogs, the Service has not completed any consultations or adopted protective measures. “The EPA acknowledges that scores of pesticides may be dangerous to California’s rare red-legged frogs, but nothing’s been done about it,” said Jeff Miller, a conservation advocate with the Center. “This three-year delay violates the Endangered Species Act and jeopardizes the future of the largest native frog in California.” Historically abundant throughout California, red-legged frogs have declined in numbers over 90 percent and have disappeared from 70 percent […]

Corporate Pressure Defeats Science on Methyl Iodide

Friday, December 3rd, 2010

(Beyond Pesticides, December 3, 2010) Ignoring the assessments of top U.S. scientists and its own Scientific Review Committee, the California Department of Pesticide Regulation (DPR) announced its approval on December 1, 2010 for use of methyl iodide, a potent carcinogen and water contaminant, as a fumigant in the state’s strawberry fields, nut orchards, and flower farms. The news comes one day after press events in eight California cities urging DPR to deny its approval, and after Washington State decided to not allow use of the chemical.Ӭ Methyl iodide poses great risk to farmworkers and those who live near fields where it will be applied as well as to air and waterways, should it escape into the surrounding environment. It is on California’s official list of known carcinogenic chemicals and has been linked to serious risks in reproductive and neurological health. A coalition of farmworker, farm, public health and environmental groups is calling on the administration of governor-elect Jerry Brown to work with his agency staff to undo this approval, and deny the use of methyl iodide in California. Specifically, the groups call on Brown to: Ӣ Follow the recommendation of John Froines, PhD, Chair of the Scientific Review Committee, to […]

UK Beekeepers End Sponsorship Deal with Pesticide Industry

Monday, November 22nd, 2010

(Beyond Pesticides, November 22, 2010) The British Beekeepers’ Association (BBKA) last week announced plans to end its controversial practice of endorsing pesticides for financial benefit from leading chemical manufacturers. The endorsement of four products as “bee-friendly” caused outrage among many beekeepers because one of the companies, Bayer Crop Science, makes pesticides like imidacloprid, an insecticide widely implicated in the deaths of honeybees worldwide. The 135-year-old charity endorsed pesticides used to combat the varroa mite that is linked to the collapse of colonies as “bee-friendly.” In return, for the past 12 years the association has received ÂŁ17,500 ($27,949) a year from Bayer Crop Sciences and Syngenta. This relationship angered many members and some left the association. However, the BBKA denies that it has bowed to pressure from members who have been increasingly critical of its relationship with Bayer and other chemical companies. In a statement sent out this week to the secretaries of local beekeeping associations across the UK, the BBKA’s president, Martin Smith, said: “Following discussion with the companies involved, the BBKA trustees have decided that endorsement and related product-specific payments will cease as soon as practically possible.” He added: “The four products subject to BBKA endorsement are of declining […]

Australian Government Bans Toxic Pesticide Endosulfan

Friday, October 15th, 2010

(Beyond Pesticides, October 15, 2010) Reversing previous rulings that claimed that the toxic pesticide endosulfan was “safe,” the Australian Pesticides and Veterinary Medicines Authority (APVMA) announced its decision Tuesday to finally cancel the registration of the highly hazardous chemical. Recent assessments by the Australian government’s Department of Sustainability, Environment, Water, Population and Communities (DSEWPC) concluded that the prolonged use of endosulfan is likely to lead to adverse environmental effects via spray drift and run-off, and that these long-term risks could not be mitigated merely through use restrictions or label changes. Australia joins over 60 countries, including to the U.S. to have banned endosulfan. Endosulfan is an organochlorine insecticide that was first registered for use in the U.S. in the 1950s. It is an endocrine disruptor and exposure in male children may delay sexual maturity and interfere with sex hormone synthesis. Endosulfan also decreases semen quality, sperm count, spermatogonial cells, and sperm morphology, and contributes to other defects in male sex hormones. It is volatile, persistent, and has a high potential to bio-accumulate in aquatic and terrestrial organisms. Two-headed bass, for example, were found in the Noosa River resulting from surrounding pesticide drift from neighboring farms in Queensland, Australia. The pesticides, […]

Groups Call for Full Ban of Pesticide, Once Widely Used in Homes

Thursday, October 14th, 2010

(Beyond Pesticides, October 14, 2010) Over 13,000 organizations and individuals -consumers, parents, health advocates, farmworkers and others- from across the U.S. sent a letter to the Environmental Protection Agency (EPA) yesterday calling for a ban on the insecticide chlorpyrifos and a phase out of other organophosphate (OP) pesticides. Chlorpyrifos was phased out for residential use under a 2000 agreement between EPA and Dow Agrosciences, but continues to expose farmworkers and consumers through its use in agriculture. Also on October 13, the Endocrine Disruption Exchange (TEDX), led by renowned scientist Theo Colborn, PhD, announced the addition of chlorpyrifos to its online database, Critical Windows of Development, spotlighting research that links prenatal, low dose chlorpyrifos exposure to altered health outcomes in the brain and other organs. “Human studies have now linked prenatal exposure to chlorpyrifos with mental and developmental delays emphasizing even more the urgency to remove the product from the market,” said Dr. Colborn, President of TEDX and a signatory on the letter. “Chlorpyrifos illustrates the urgent need to be cautious, prevent further exposure and protect our children from the time they are conceived onward.” Beyond Pesticides calls EPA’s 2000 chlorpyrifos settlement with Dow a classic failure of the risk assessment […]

Two Culprits Linked to Bee Decline, More Research Needed

Friday, October 8th, 2010

(Beyond Pesticides, October 8, 2010) Scientists may have found the missing link behind the colony collapse disorder (CCD): a combination of a virus and a fungus, though more research is needed to determine the exact cause and effect that these two culprits have on CCD. Prior to this study, scientists have hypothesized that there are numerous factors, including pesticides, that depress the immune and nervous system of bees, creating a vulnerability to other factors, such as those identified in this study. Army scientists in Maryland and entomologists in Montana teamed up to find that the co-occcurrence of the viruses, the invertebrate iridescent virus (IIV) with the fungus Nosema ceranae (which was previously implicated as a culprit) consistently marked a colony collapse. The study, Iridovirus and Microsporidian Linked to Honey Bee Colony Decline was published October 6th in the online science journal PLoS One. Researchers looked at the proteins of thousands of healthy and collapsing bee colonies using mass spectrometry-based proteomics (MSP) that revealed two previously unreported RNA viruses in honey bees in North America, one of which is the IIV. Researchers say this virus is similar to a virus that was first reported in India 20 years ago, as well […]

Scientists Urge Caution with Nanomaterials in Pesticides

Thursday, October 7th, 2010

(Beyond Pesticides, October 7, 2010) Nanotechnology has played an increasing role in the world of pesticides, particularly in the form of silver nanoparticles for their antibacterial properties; however, as this field grows, scientists and researchers are becoming increasingly concerned with the potential impacts of these particles on public health and the environment. A new study by scientists from Oregon State University (OSU) and the European Union (EU) highlights the major regulatory and educational issues that they believe should be considered before nanoparticles are used in pesticides. The study was published Monday in the International Journal of Occupational and Environmental Health. “Unlike some other applications of nanotechnology, which are further along in development, applications for pesticides are in their infancy,” said Dr. Stacey Harper, PhD, an assistant professor of nanotoxicology at Oregon State University. “There are risks and a lot of uncertainties, however, so we need to understand exactly what’s going on, what a particular nanoparticle might do, and work to eliminate use of any that do pose dangers. Some of the potential benefits of nanotechnology that scientists discuss in the report are that it may provide better control and delivery of active ingredients, less environmental drift, formulations that will most […]

(Beyond Pesticides, September 30, 2010) A new study finds a clear link between a decline in wild pollinators and reduced vegetable yields in India, which researchers say will harm both the nation’s GDP as well as access to a nutritional diet. Parthiba Basu, PhD, one of the researchers from the University of Calcutta’s Ecology Research Unit, says that nutritional security in India will be affected as a result of the decline, since the vegetables that rely on pollination substantially provide essential nutrients to the population. The research team, which presented its findings at a recent British Society meeting at the University of Leeds, compared the yields of pollinator-dependent crops such as pumpkins, squash and cucumbers with pollinator-independent crops, such as cereals. The data shows that while yields of pollinator-independent crops continue to increase, the crops that are dependent on pollinators have leveled off. Though the researchers would have liked to specifically compare pollinator abundance over the years, this kind of data is not currently available in India. The use of domesticated bees for pollinating crops is not widespread in India and across South Asia, according to Dr. Basu. He attributes the “political noise” in the U.S. and Europe on the […]
