(Beyond Pesticides, August 5, 2016) Concerned health officials in Miami, Florida are investigating suspicions that Zika-spreading mosquitoes have become resistant to the pesticides commonly used synthetic pyrethroid insecticides used in mosquito control. As the region works to contain a Zika outbreak in northern Miami, officials are beginning to recognize that broadcast pesticide applications are not effective at controlling populations, and are looking into cases in the U.S.  and in other parts of the world of mosquitoes developing resistance to chemical controls, or whether other factors are at work. At the same, the broadcasting of the pesticides by truck and plane and the resulting exposure to people and the environment also raise serious health issues. The Aedes aegypti mosquito, which has the ability to live indoors and reproduce even in tiny pools of water, is the primary way the Zika virus is spread, although there are reports that the disease can also be transmitted through sexual contact. Zika virus has been linked to cases of microcephaly, in which babies are born with underdeveloped brains. The virus has been detected in several Latin American countries, including Brazil where the outbreak was first observed and linked to increased cases of microcephaly. However, locally […]

(Beyond Pesticides, July 21, 2016) An investigative report released yesterday by Center for Biological Diversity (CBD) concludes  that, over the past six years, the U.S. Environmental Protection Agency (EPA) has approved nearly 100 pesticide products with chemical mixtures that elevate the formulations’  toxicity, but are not specifically evaluated  by the agency. CBD finds that these formulations add  more stress to already-jeopardized pollinators and rare plants. The report Toxic Concoctions: How the EPA Ignores the Dangers of Pesticide Cocktails, highlights a long-running blind spot within EPA’s pesticide evaluation program, which Beyond Pesticides has long sounded the alarm on: the risk associated with combining mixtures of different pesticide active ingredients, which independent science shows may be more toxic than a single active ingredient by itself, also known as pesticide synergism. The mixtures occur as a result of multiple ingredients in individual products or  because of exposure to multiple pesticide product residues in food, air, water, and land areas, such as lawns, playing fields, and parks. “It’s alarming to see just how common it’s been for the EPA to ignore how these chemical mixtures might endanger the health of our environment,” said Nathan Donley, Ph.D., a scientist with the CBD, and author of […]

(Beyond Pesticides, July 19, 2016) Exposure to common pesticides at levels often found in the environment can have subtle but significant impacts on the behavioral health of fish, amphibians and other aquatic invertebrates. According to researchers at Northern Arizona University, who analyzed data from nearly 40 experiments to reach their conclusion, fish and amphibians swam 35% slower and were 72% less active after pesticide exposure. Chemical Class Type Example Pesticides Carbamates Insecticide Carbaryl, Aldicarb Organochlorine Insecticide DDT, Endosulfan, Chlordane Organophosphates Insecticide Diazinon, Chlorpyrifos Organotins Biocide Tributyltin Phosphonoglycines Herbicide Glyphosate, Glufosinate Pyrethroids Insecticide Permethrin, Bifenthrin, Esfenvalerate Triazines Herbicide Atrazine, Simazine The study, published in Science of the Total Environment, found that the overall effect on aquatic wildlife varied based on the chemical class the animals encountered. While pyrethroids, carbamates, and organophosphates resulted in a significant decrease in swim speed, triazines and phosphonoglycines showed no overall effect. Pyrethroids, carbamates, organophosphates, organochlorines, and organotins decreased activity, while phosphonoglycines had no overall effect, and triazines actually increased activity. “I didn’t think that we would see [an effect] across such a wide range of pesticides so consistently, but we did,” said study co-author, Catherine Propper, PhD to KNAU, “and that leads to some concerns about […]

(Beyond Pesticides, July 13, 2016) California’s Office of Environmental Health Hazard Assessment (OEHHA) has announced that atrazine, its chemical cousins,  propazine,  simazine,  and its break down triazine compounds des-ethyl atrazine (DEA),  des-isopropyl atrazine (DIA)  and  2,4-diamino-6-chloro-s-triazine (DACT)  would be added to the list of chemicals known to the state to cause reproductive toxicity for purposes of the state’s Proposition 65. The formal listing has been delayed and will not be effective until July 15, 2016 due to litigation from the manufacturer, Syngenta, which opposes the listing. In 2014 the state announced its Notice of Intent to list the triazines: atrazine, propazine, simazine and their breakdown products under Proposition 65 — the state’s law on toxic chemicals. The listing of these chemicals was initially to be effective on August 3, 2015. However, Syngenta, manufacturer of atrazine, challenged the listing decision, leading to a delay in the formal decision. Syngenta Crop Protection v OEHHA  (Sacramento Superior Court case#34-2014-800001868). Syngenta’s challenge was unsuccessful and now the official listing can move forward, in spite of Syngenta’s pending appeal. The six chemicals will now be known as reproductive toxicants in the state of California effective July 15, 2016. See listing notice. http://oehha.ca.gov/media/downloads/crnr/listingnoticetriazines070516.pdf Proposition 65, officially […]

(Beyond Pesticides, July 11, 2016) The Centers for Disease Control and Prevention (CDC) and the U.S. Environmental Protection Agency (EPA) announced last Wednesday, July 6 that Zika is spreading rapidly in Puerto Rico, and recommends aerial spraying of the toxic pesticide Naled for mosquito control, much to the dismay of many area farmers, activists and concerned citizens who feel that the decision was made without consultation or information provided to the local population. Aerial spraying of pesticides have long been used for mosquito control, but many experts believe that these methods fail to sufficiently manage mosquito populations, increase pesticide resistance, and kill other species that would have acted as a natural predator to mosquitoes. Many experts  agree that combating mosquito-borne diseases should include good surveillance and scientific understanding for controlling mosquito populations, including a focus on  eliminating or managing  breeding areas,  utilizing  biological controls, exclusion from indoor environments with screening, and repellents. An efficient mosquito management strategy emphasizes public awareness, prevention, and monitoring methods. However, if these methods are not used properly or in time, communities must determine if they should risk exposing vulnerable populations to potentially harmful diseases caused by mosquitoes or to chronic or deadly illnesses caused by […]

(Beyond Pesticides, July 8, 2016) Researchers at the University of Montana (UM) recently released a study that found a lack of government data and accountability on  the use of herbicides on public lands to kill invasive and non-native plants. The report raises serious questions about the widespread management practice, which the researchers say may be causing more harm than good. UM researchers, Cara Nelson, Ph.D. and Viktoria Wagner, Ph.D., along with two researchers from Canada, looked at government agencies and agricultural statistics companies in the U.S., Canada, and Mexico to find their data. The study found that the government agencies in Canada and Mexico kept no archived database of herbicide usage for invasive plant management. In the U.S., five out of seven agencies that were contacted by the researchers tracked herbicide usage, and only four of those agencies shared their data. These agencies include the Bureau of Indian Affairs, Bureau of Land Management, Fish and Wildlife Service, and National Park Service. The U.S. Forest Service, which oversees 193 million acres in the U.S., declined to share its data on herbicide use. The report found that even the agencies that did share their data did not consistently archive information on the […]

(Beyond Pesticides, June 8, 2016) With years of data documenting the harmful impacts of the herbicide atrazine on aquatic organisms and other wildlife, a recent U.S. Environmental Protection Agency (EPA) assessment now concludes that this widely used chemical poses risks to fish, amphibians, aquatic invertebrates, and even birds, reptiles and mammals. Atrazine is a potent endocrine disruptor with strong associations with birth defects, sex reversal and hermaphroditism in organisms, and whose risk to environmental and human health is exacerbated by pervasive surface, ground and drinking water contamination. Last week, EPA released its triazine ecological risk assessments for atrazine and its chemical cousins simazine, and propazine. The assessments evaluated risks to animals and plants including, amphibians, birds, mammals, fish, reptiles, aquatic invertebrates, aquatic plant communities, and terrestrial plants.  EPA is currently in the registration review process for these chemicals. For atrazine, EPA concludes, “aquatic plant communities are impacted in many areas where atrazine use is heaviest, and there is potential chronic risks to fish, amphibians, and aquatic invertebrate in these same locations. In the terrestrial environment, there are risk concerns for mammals, birds, reptiles, plants and plant communities across the country for many of the atrazine uses.” Levels of concerns were […]

(Beyond Pesticides, June 1, 2016) A study  by researchers at Purdue University has concluded  that honey bees collect most of their pollen from non-crop plants that are frequently contaminated with agricultural and urban pesticides. The researchers found this to be true even in places where croplands dominate the area.  The study, which detected neonicotinoids, pyrethroids, fungicides, and others, highlights the large number of toxic pesticides to which bees are exposed to in the environment. Researchers collected pollen from Indiana honey bee hives at three sites over 16 weeks. The hives were placed in a variety of settings, such as an open meadow with wildflowers, woody shrubs and trees present (non-agricultural), the border of a corn field that was treated with the neonicotinoid clothianidin and three fungicides, and the border of a non-treated corn field. The pollen samples that were collected by the bees represented up to 30 plant families and contained residues from pesticides spanning nine chemical classes. The researchers found 29 pesticides in pollen from the meadow site, 29 pesticides in pollen from the treated cornfield, and 31 pesticides in pollen from the untreated cornfield. The most common chemical products found in pollen from each site were fungicides and […]

(Beyond Pesticides, May 27, 2016) Oxitec, a self-described pioneer in using advanced genetics to control target  insects, has petitioned the U.S. Food and Drug Administration (FDA) to grant emergency approval of genetically engineered (GE) mosquitoes to fight the spread of the Zika virus. Oxitec has proposed a trial to determine the efficacy of their self-limiting mosquitoes for the control of Aedes aegypti, a type of mosquito known to transmit the Zika virus, in Key Haven, Monroe County, Florida. However, some in the environmental community are concerned about the possible non-target effects of releasing these genetically modified mosquitoes into nature and urge additional research in the lab. The plan for a release of these GE mosquitoes has been in the works for a while. In February 2015, it was reported that the Florida Keys Mosquito Control District (FKMCD) was working alongside Oxitec to release these GE mosquitoes, but, at the time, the plan had not yet been finalized. A change.org petition against the release garnered over 146,000 signatures and continues to grow, with numbers around 168,000 to this date. In February 2016, Oxitec submitted a draft environmental assessment to FDA, and a month later, FDA published a preliminary finding of no […]

(Beyond Pesticides, May 19, 2016) Using fear without facts, Congress is yet again attempting to gut Clean Water Act (CWA) provisions that protect waterways and communities from excessive pesticide pollution. In a move that was blasted by House Democrats this week, HR 897  (which was introduced as the Reducing Regulatory Burdens Act of 2015) was renamed the  Zika Vector Control Act, despite the fact that the bill does not actually do anything to address the threat of Zika. The legislation was defeated Tuesday on a suspension vote, 262-159, however the bill will be going to the Rules Committee on Monday, with anticipated House floor activity on Tuesday, May 24. (Take action: urge your representative to oppose HR 897.) “In a brazenly political act, the Republican leadership is trying to mask gutting the Clean Water Act as having something to do with fighting Zika,” Drew Hammill, spokesman for House Minority Leader Nancy Pelosi (D-CA), said in a statement to The Hill. “This bill has nothing to do with Zika and everything to do with Republicans’ relentless special interest attacks on the Clean Water Act,” he said. “It will do nothing to stem the growing threat of the Zika virus.” The bill […]

(Beyond Pesticides, May 10, 2016) Following an apparent accidental release of documents relating to the safety of the herbicide glyphosate, late last month the U.S. Environmental Protection Agency (EPA) also released and then retracted a preliminary ecological risk assessment of another toxic herbicide, atrazine. Under federal law, every pesticide registered in the United States is required to undergo a 15-year registration review to analyze human health and environmental impacts and determine whether the chemical’s use should continue another 15 years. The last decade and a half have seen plethora of studies underscoring that atrazine is harmful to human health, and poses unreasonable adverse risks to ecological health, despite attempts by its major manufacturer, Syngenta, to silence and discredit its critics. EPA’s preliminary ecological risk assessment finds that for current uses at prescribed label rates, atrazine may pose a chronic risk to fish, amphibians, and aquatic vertebrate animals. Where use is heavy, the agency indicates that chronic exposure through built-up concentrations in waterways is likely to adversely impact aquatic plant communities.  Levels of concern, a wonky equation that EPA produces to measure risk, were exceeded for birds by 22x, fish by 62x, and mammals by 198x. Even reduced label rates were […]

(Beyond Pesticides, April 12, 2016) Two commonly used pesticides are “likely to adversely affect” 97% of species listed under the Endangered Species Act (ESA), according to a first of its kind national assessment by the U.S. Environmental Protection Agency (EPA). The determination is part of a settlement reached by EPA and the Center for Biological Diversity, which requires the agency to complete a review of the impact of organophosphate pesticides chlorpyrifos, malathion, and diazinon by December 2017, and two carbamate class pesticides, methomyl and carbaryl, by the end of 2018. Under ESA Section 7, any agency action that it  authorizes, funds, or carries out must find that it  “is not likely to jeopardize the continued existence of any endangered species or threatened species or result in the destruction or adverse modification of habitat.” Under ESA, EPA is required to consult with the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) when registering a pesticide, in order to mitigate risks to endangered species. However, EPA routinely disregards this requirement, and has been sued numerous times for failing to ensure adequate protections for endangered species. Although CBD’s original lawsuit targeted potential pesticide impacts on California’s threatened red-legged frog, […]

(Beyond Pesticides, March 1, 2016) Under the terms of an agreement reached lasted month, the U.S. Fish and Wildlife Service (FWS) will begin studying the effects of four commonly used herbicides on the health of 1,500 endangered species in the United States. Based on the terms of the settlement, the result of a series of lawsuits launched by the Center for Biological Diversity (CBD), FWS must develop a  plan to mitigate the effects of glyphosate, atrazine, and its chemical cousins propazine and simazine, on any threatened or endangered species. “This agreement will result in long-overdue protections for our country’s most endangered species,” said Brett Hartl, endangered species policy director at CBD. “Once the Fish and Wildlife Service completes its analysis, and the public finally learns just how toxic and deadly these pesticides are to endangered species, we hope that the government will ultimately take most of these products off the shelf.” Under the Endangered Species Act (ESA), the Environmental Protection Agency (EPA) is required to consult with FWS and the National Marine Fisheries Service (NMFS) on the impacts of pesticides on endangered species when it registers a chemical under federal pesticide law (the Federal Insecticide Fungicide and Rodenticide Act, or […]

(Beyond Pesticides, February 19, 2016) Pesticide mixtures are more harmful than individual pesticides, according to a University of California, Los Angeles (UCLA) study that focuses on three commonly used fumigants — chloropicrin, Telone, and metam salts. The study also concludes that, while California law requires the Department of Pesticide Regulations (DPR) and county agricultural commissioners to assess these kinds of cumulative risks when regulating pesticides, they have so far failed to do so. The report, titled Exposure and Interaction — The Potential Health Impacts of Using Multiple Pesticides: A Case Study of Three Commonly Used Fumigants, was published by the Sustainable Technology and Policy Program, based in the UCLA School of Law and the UCLA Fielding School of Public Health. The case study of the three fumigants, which are commonly applied together in California on high value crops, such as strawberries, tomatoes, tree nuts, and stone fruits, finds that: These pesticides may interact to increase the health risk for California farm workers and residents, Workers and residents are regularly exposed to two or more of these pesticides simultaneously, and DPR does not regulate the application of multiple pesticides to prevent or decrease risks to human health, despite having authority to […]

(Beyond Pesticides, February 3, 2016) Speaking to The Guardian, a leading Kenyan entomologist warns that spraying pesticides will fail to deal with the Zika virus. Just recently the World Health Organization (WHO) declared the virus a public health emergency over growing concerns that the virus is linked with microcephaly. Aerial and ground applications of pesticides have long been used for mosquito control, but many believe that these methods fail to sufficiently control mosquito populations, promote resistance and kill other species that would have acted as a natural predator to mosquitoes. Dino Martins, PhD, a Kenyan entomologist in an interview with The Guardian said that while pesticides can reduce the population of  flying adult mosquitoes that transmit the virus, they will fail to deal with the epidemic that threatens to become a global pandemic, and warns that spraying landscapes is extremely dangerous.  “It is a quick fix but you pay for it. You kill other species that would have predated on the mosquitoes. You also create a mosaic of sprayed and unsprayed low densities of chemicals that fosters the rapid evolution of resistance.” Mosquitoes have very short life cycle (a week or less), increasing the probability that each succeeding generation is […]

(Beyond Pesticides, January 12, 2016) Late last week in a precedent-setting move, Campbell Soup Company announced its support for federal mandatory labeling of foods containing genetically engineered (GE) ingredients. If such labeling does not come soon, the company also indicated it is prepared to voluntarily label all products it produces that  contain GE ingredients. Agri-Pulse reported, “Campbell made clear that it still supported the use of genetic engineering in agriculture but said that there is a need for national labeling standards that would preempt state standards.” Campbell’s President and CEO Denise Morrison, ““I want to stress that we’re in no way disputing the science behind GMOs or their safety. The overwhelming weight of scientific evidence indicates that GMOs are safe and that foods derived from crops using genetically modified seedsare not nutritionally different from other foods,” Morrison wrote.” Ms. Morrison said that the company is against a patchwork of regulation across the states.  In its release Campbell issues a sample label, which states:  “Partially produced with genetic engineering. For more information about GMO ingredients visit WhatsinMyFood.com.” Prior to the announcement, Campbell Soup’s membership to the umbrella group the Grocery Manufacturers Association  pitted it against consumer, health, and environmental organizations, and […]

(Beyond Pesticides, October 22, 2015) With increasing consumer concern about genetically engineered (GE) food, yesterday  the U.S. Senate Committee on Agriculture, Nutrition, and Forestry held a hearing,  entitled Agriculture Biotechnology: a Look at Federal Regulation and Stakeholder Perspectives, that critics called lopsided. Most witnesses characterized GE food as safe or side-stepped the issue of safety, as government witnesses refused to distinguish GE from conventional food and opposed food labeling. “This is the first time in 10 years we’ve had a hearing on biotech. I guess we’re a little late, but we’re here,” said chair of the committee, Senator Pat Roberts (R-KS). The ranking  minority member of the committee, Senator  Debbie Stabenow (D-MI)  said,  “Biotechnology is proven to be safe, beneficial, and I believe will play a major role in helping to solve these dual global challenges of climate change and global food security,” Central to the hearing is the the issue of labeling food products containing GE crops. Senator Stabenow called for the adoption of legislation on GE food labeling, presumably with language that will preempt the authority of states to adopt more stringent labeling standards. Senator Stabenow said that she wants labeling that “doesn’t stigmatize biotechnology.” The GE food […]

(Beyond Pesticides, August 19, 2015) Local fogging for  mosquito control turned tragic for a Palo Alto, California beekeeper who lost hundreds of honey bees from his backyard hives. The beekeeper, who also produces organic honey, now fears his honey is contaminated. The fogging, which occurred last month, was in response to positive tests for West Nile virus in mosquito samples. Many mosquito control pesticides are toxic to honey bees and given the declining populations of pollinators, vector control officials are being asked to carefully consider the risks associated with pesticide spraying. According to the local NBC affiliate, beekeeper Rondolph Tsien believes he was not given sufficient time to protect his bees from the mosquito fogging and, despite trying to cover his hives with a tarp to protect his bees from drifting pesticides, many were lost. A mosquito sample tested positive for West Nile virus about one mile from Mr. Tsien’s home, putting his property in the catchment area for fogging. Mr. Tsien worries the surviving bees will produce contaminated honey that can no longer be labeled organic. A Santa Clara County Vector Control representative stated during an interview that the county uses  an “extremely low dose” of pesticides during fogging […]

(Beyond Pesticides, July 16, 2015) The latest former U.S. Environmental Protection Agency (EPA) official to take advantage of the revolving door between EPA and the pesticide industry is Nader Elkassabany, PhD, former branch chief of the Risk Assessment and Science Support Branch in the Antimicrobial Division in the Office of Pesticide Programs. CropLife America announced last week that it has hired Dr. Elkassabany to serve as senior director of environmental policy, responsible for the pesticide trade group’s regulatory strategies on environmental policy. He will also help manage the company’s Environmental Risk Assessment Committee and its working groups. In a statement, CropLife America President and CEO Jay Vroom considers his expertise invaluable. This is no surprise, given that Dr. Elkassabany brings with him 15 years of experience working in  the registration and re-registration of pesticide active ingredients in the Office of Pesticide Programs (OPP) at EPA. This will undoubtedly be beneficial for the trade association, which represents major agricultural chemical manufactures like Bayer CropScience, Dow AgroSciences, and DuPont Crop Protection. According to a statement from CropLife, Dr. Elkassabany received three EPA Bronze Medals for Commendable Service. He left EPA in 2012 to work for another big name in consumer pesticides,  S.C. […]

(Beyond Pesticides, July 6, 2015) With the release of its  Tier 1 screening results  for the first 52 pesticide chemicals (active and inert ingredients) evaluated under  the Endocrine Disruptor Screening Program (EDSP), the U.S. Environmental Protection Agency (EPA) is at odds with a large body of scientific evidence worldwide that identifies many of these chemicals, most notably the herbicides  2,4-D  and  atrazine,  as interacting with the endocrine system or acting as endocrine disruptors. Independent scientific data has shown these chemicals to interfere with the hormone system. EPA’s EDSP is a multi-step process used to ensure that exposure to chemicals does not result in adverse human health and environmental effects that canoccur from the disruption of hormones. The two-tiered screening and testing system requires that EPA identify which chemicals are able to interact with the endocrine system, specifically with three hormonal pathways — estrogen, androgen, and thyroid — in Tier 1. Tier 2 is designed to go one step further, requiring EPA to determine endocrine effects across taxa (e.g. mammals, birds, amphibians, and invertebrates) as well as potential effects on non-endocrine systems (e.g. neurological, immunological, hepatic, and renal).  According to EPA, Tier 1 screening data are the best way to determine […]

(Beyond Pesticides, June 25, 2015) The U.S Environmental Protection Agency (EPA) announced Tuesday that it will analyze the effects of two of the most commonly used pesticides in the United States, glyphosate and atrazine, along with atrazine chemical-cousins propazine and simazine, for their impacts on 1,500 endangered plants and animals. The announcement marks an agreement between EPA and Center for Biological Diversity (CBD) on a proposed settlement amending a 2010 court order that  established a schedule to complete effects determinations for 75 chemicals on 11 species in the San Francisco (SF) Bay Area. According to EPA, 59 of the 75 pesticides have been evaluated and subject to  effects determinations, however for the remaining 16 pesticides, EPA and CBD agreed that it would be more efficient and environmentally significant to complete nationwide effects determinations, rather than limit their focus to the SF bay area listed species. The agency has committed to completing the assessments by June 2020. The initial lawsuit was filed by CBD in May 2007 against EPA for violating the Endangered Species Act by registering and allowing the use of scores of toxic pesticides in habitats for 11 San Francisco Bay Area endangered species without determining whether the chemicals […]

(Beyond Pesticides, May 28, 2015) The same day that trade representatives from United States met with Secretary-General Catherine Day of the European Commission (EC), she sent a letter to the EC’s Environment Director-General Karl Falkenberg telling him to scrap draft criteria that could have led to a ban on over 30 endocrine (hormone) disrupting chemical (EDCs) in the European Union (EU). As reported by The Guardian, with resources obtained by Pesticide Action Network- Europe (PAN-Europe), the U.S. Chambers of Commerce and European-based chemical manufacturers (including Dupont, Bayer, and BASF) pushed to change the EC’s criteria for evaluating EDCs because they fear it would impede EU-US negotiations on  the Transatlantic Trade and Investment Partnership (TTIP). Two regulations, one concerning “plant pest protectants” (EU 1107), and another on biocidal products (EU 528), should prohibit from use chemicals categorized as having endocrine disrupting properties that may cause adverse effects in humans. However, last year, when the EC released a roadmap for evaluating EDCs, recommendations fell far short of what health advocates assert that EU regulations require. Earlier this year, the Guardian reported that a scientific paper that would have adequately established ways to identify problematic EDCs was suppressed by EU officials at the […]
