Nitrate Pollution in Groundwater Linked to Birth Defects, Cancers and Thyroid Problems

(Beyond Pesticides, October 6, 2016) According to a report published last week by the Iowa Environmental Council (IEC), the associations between elevated levels of nitrate in drinking water and health risks go well beyond the “blue-baby syndrome” and nitrate concentrations lower than the drinking water standard may be harmful through long-term exposure. The lead author of the report, Ann Robinson, Agricultural Policy Specialist at IEC, stated that the focus was on “significant findings that multiple studies have associated with nitrate in drinking water, including birth defects, bladder cancer and thyroid cancer.”  Nitrate is a common groundwater contaminant that is sourced mainly from chemical fertilizers and animal waste. Nitrate is a common contaminant of drinking water, particularly in agricultural areas where nitrogen fertilizers are used. In 1962, the U.S. Environmental Protection Agency (EPA) established the drinking water standard of 10 mg/L of nitrate to prevent blue baby syndrome, a fatal infant blood disease. In addition to Iowa, the U.S. Geological Survey has also identified the following states as areas with high risk clusters from nitrate contamination to groundwater: Oklahoma, Kansas, Nebraska, North and South Dakota, Illinois, Minnesota, Pennsylvania, and Maryland. The report reviewed studies conducted in the U.S., Canada, and Australia […]

Former Undisclosed Ingredients in Pesticide Products Found in Fish, Birds, and Dolphins

(Beyond Pesticides, October 4, 2016) Chemicals previously used as  inert ingredients in pesticide formulations have been detected in a wide range of North American wildlife species, according to research published in the journal Environmental Science and Technology. The compounds, perfluroalkyl phosphinic acids (PFPIAs), were widely used as anti-foaming agents in pesticide formulations until 2006, when the U.S. Environmental Protection Agency took regulatory action to cancel  their use, citing “human health and environmental risks of concern.” However, the chemicals continue to be used today in consumer goods, including carpet cleaning formulas. While scientists did not find what they would consider high concentrations of the chemicals in wildlife, the ubiquity of the detections was found to be most concerning. Researchers detected the presence of PFPIAs in the blood of 100% of animals sampled. This includes northern pike in Montreal, Canada, cormorants from the Great Lakes, and bottlenose dolphins from Sarasota Bay, Florida. “We aimed for diversity: air-breathing versus water-breathing, differences in habitat, different taxonomic groups,” Amila O. De Silva, PhD, coauthor of the study, said to CNN. Part of the reason for the wide range of detection lies with the properties of these chemicals. They are highly stable and resist degradation from […]

Maryland Begins Spraying for Zika before Finding Infected Mosquitoes

(Beyond Pesticides, September 1, 2016) With the apparent mosquito transmission of the  Zika virus in Florida, local officials around the United States have been feeling pressure to step-up preemptive mosquito spraying, prior to the virus actually emerging  locally in infected mosquitoes. The Zika virus has been contributing to public anxiety in the U.S. for several months and, because of this, the state of Maryland has started spraying with hazardous insecticides. The state has made targeting mosquitoes its  number one priority, while many argue that the state’s spraying  puts the well-being of residents at risks. As of August 24, there are 77 travel-associated cases of Zika in the state of Maryland. Without a finding of infected mosquitoes in the state, the Maryland Department of Agriculture’s (MDA) Mosquito Control Program is focusing its  control actions on female (the ones that bite) aedes albopictus, commonly known as Asian tiger mosquitoes, the most common type of mosquito in Maryland that studies indicate “has the potential” to transmit the Zika virus. MDA’s Mosquito Control Program implements the state’s mosquito management, which is conducted in accordance with an undefined  Integrated Pest Management (IPM)  program; basing the  approach broadly on prevention, monitoring, and control of mosquitoes. As […]

Fighting Zika – Growing Concerns over Pesticide Resistance

(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 […]

Investigative Report Uncovers Dangerous Pesticide Misuse on Golf Courses in New York

(Beyond Pesticides, August 4, 2016) Complaints about a green residue that appeared on golfers’ shoes at Rye Golf Club in New York last spring prompted an investigative report by The Journal News/lohud.com, that  revealed what reporters are describing a region-wide “environmental toxic time bomb” caused by the over and misuse of pesticides throughout the state. The investigation uncovered (i) gaps in the oversight of millions of pound of toxic pesticides applied throughout the Lower Hudson Valley, (ii) heightened health risks in Westchester and Rockland counties where pesticides are used the most, (iii) significant flaws in pesticide data collected in the state of New York, and (iv) the failure of authorities to catch the illegal sale and use of unregistered pesticides. Rye Golf Club, which turned into a “field of dustbowls” within weeks of the green residue appearing on golfer’s shoes, had to close 18 putting greens, leading members to demand thousands of dollars in refunds and city leaders to address the severely damaged city-owned golf course. The cause of the mysterious green residue was later revealed to be the result of an application of a contaminated batch of the fungicide ArmorTech ALT 70, whose active ingredient is azoxystrobin. Rye Golf […]

Terminix To Pay Delaware Family $87 Million Settlement for Poisoning with Methyl Bromide in U.S. Virgin Islands

(Beyond Pesticides, August 3, 2016) Home pest control giant Terminix reached a tentative settlement agreement this week of $87 million with  the  Esmond family for the severe poisoning of the mother, father and two teenage children with the highly neurotoxic pesticide fumigant  methyl bromide.  The company treated  a neighboring unit  to  their vacation residence  last spring  at a  condo resort complex in St. John, U.S. Virgin Islands. This amount is in addition to $3 million already paid to the family to cover the insurance deductible, and an undisclosed amount that the company’s insurance carriers have agreed to pay pursuant to their general liability insurance policies, according to an earnings report filed by the Terminix’s parent company, ServiceMaster Global Holdings, Inc. of Memphis, Tennessee. Stephen Esmond became paralyzed after the March 2015 incident, while his two sons spent weeks in critical condition. The mother,  Theresa Devine is still recovering. Beyond Pesticides’ executive director, Jay Feldman, spoke to CBS Evening News August 2 on the poisoning. Watch news piece  here.   Methyl bromide is a restricted use pesticide and is not registered for residential use, according to the U.S. Environmental Protection Agency’s (EPA) 2013 Methyl Bromide Preliminary Workplan. It was taken off […]

Mixtures of Multiple Pesticide Ingredients in Products Not Evaluated by EPA for Elevated Toxicity

(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 […]

Common Pesticide Exposure Alters Behavior of Fish and Amphibians

(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 […]

CDC, EPA Urge Aerial Mosquito Spraying in Puerto Rico Amid Protest

(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 […]

Government Lacks Data on Widespread Herbicide Use on Public Lands

(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 […]

Federal Court Finds USDA Process for Allowing Pesticide-Contaminated Compost Improper and Stops Use

(Beyond Pesticides, June 22, 2016) In a ruling that organic advocates say is critical to the integrity of the USDA organic label, a U.S. District Court judge found Monday that the U.S. Department of Agriculture (USDA) violated public process when it decreed that pesticide-contaminated compost is allowed in organic production. Three groups that bridge environmental, consumer, and farmer interests sued USDA for ruling that green waste compost, which comes from lawn clippings and plants, may contain levels of the insecticide bifenthrin and other pesticides that have not been approved for use in organic systems through proper public hearing and comment procedures. The case focused principally on whether USDA, in failing to conduct a formal public review, was operating “at its whim.” The court found that is exactly what USDA did and ordered the agency to stop allowing the use of contaminated compost by August 22, 2016. U.S. District Judge Jacqueline Scott Corley of the Northern District of California found that USDA’s National Organic Program (NOP) operated without the required notice and comment. She explained, “the reach of the Agency’s  new rule stretches beyond bifenthrin and instead allows green waste or green waste compost used in organic production to contain any […]

Glyphosate Approval in EU Up in the Air

(Beyond Pesticides, June 10, 2016) A proposal for a temporary ‘technical extension’ of the EU approval of the herbicide glyphosate failed to secure the support of a majority of EU governments at a meeting of the EU standing committee on plants, animals, food and feed on Monday. This action may force the withdrawal of the herbicide, widely sold as Monsanto’s Roundup, from shelves if no decision is reached by the end of the month, when its license expires. After a proposal to renew the license for glyphosate for up to 15 years failed to win support in two meetings earlier this year, the EU executive offered a limited 12 to 18 month extension to allow time for further scientific study. Yet, despite this compromise, the proposal failed to win the support of member states representing at least 65% of the EU’s population, which is needed for adoption, an EU official told The Guardian. Seven member states abstained from Monday’s vote, 20 backed the proposal and one voted against, a German environment ministry spokeswoman said. According to the news source, Germany was among those that abstained from Monday’s vote. Of note is that Bayer, the German chemical company, recently offered to […]

Public Comment Needed to End Atrazine Use after EPA Confirms Threat to Wildlife

(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 […]

EPA Judge Rejects Bayer’s Challenge to Keep Flubendiamide on Market after Agency Pulls Conditional Registration

(Beyond Pesticides, June 6, 2016) Bayer CropScience’s appeal of the cancellation of their toxic pesticide flubendiamide by the U.S. Environmental Protection Agency (EPA) was rejected by EPA’s Chief Administrative Law Judge (ALJ) Susan Biro on Thursday, June 1. Judge Biro dismissed the complaints, saying that the agency was acting within its authority when it pulled its approval for the pesticide earlier this year after the two manufacturers, Bayer CropScience and Nichino America, failed to meet the terms laid out in a 2008 conditional registration. A startling number of pesticides, nearly 65% of the more than 16,000 pesticides now on the market, were first approved by the process of “conditional registration,” a loophole in which EPA allows new pesticides on the market without the full range of legally mandated toxicity tests for a full registration. Meanwhile, the Canadian Pest Management Regulatory Agency finalized its  decision to discontinue granting new conditional registrations, also on June 1. In 2008, EPA granted Bayer a “conditional” registration for flubendiamide, a classification that allows a new pesticide to be registered and used in the field, despite outstanding data points on its toxicological impact. In this case, original data submitted to EPA by Bayer showed concern over […]

Study Finds Honey Bees Frequently Collect Contaminated Pollen from Non-Crop Plants

(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 […]

Maryland Residents Asked to Urge Governor to Sign Pollinator Protection Act, Under Threat of Veto this Week

(Beyond Pesticides, May 26, 2015) Maryland’s historic Pollinator Protection Act, (SB 198 and HB 211) may be in danger. Last month, lawmakers approved the bill by a 98-39 vote in the Maryland House of Delegates, however it faces the possibility of a veto by Governor Larry Hogan (R). While the governor’s office says that the bill is currently under review, according to local news source WBAL, the governor is prepared to veto the bill, which he has until tomorrow, Friday, May 27, to do. If the governor does veto the bill, Maryland’s Pollinator Protection Act will go back to the legislature for an override vote, which will take place in early 2017. Meanwhile, beekeepers continue to lose their bees at unprecedented rates. Last week, we reported results of 2015-16 Colony Loss Survey, which show no sign that the crisis of abating. According to the survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. WBAL reports that the governor is likely to veto the bill because of […]

The Controversy Heats Up on the Cancer Causing Properties of Roundup

(Beyond Pesticides, May 18, 2016) The controversy continues on glyphosate’s (Roundup) cancer causing properties, as some question the influence of the chemical industry and Monsanto, Roundup’s manufacturer, on newly announced  findings, according to The Guardian.  A joint review by the United Nations (UN) and World Health Organization (WHO) on  glyphosate, released this week,  seems to contradict earlier findings (at least based on food exposure) of the International Agency for Research on Cancer (the preeminent scientific body on carcinogenesis in the world), which classified Roundup as a “probable human carcinogen.” The Guardian disclosed, “Professor Alan Boobis, who chaired the UN’s joint FAO/WHO meeting on glyphosate, also works as the vice-president of the International Life Science Institute (ILSI) Europe. The co-chair of the sessions was Professor Angelo Moretto, a board member of ILSI’s Health and Environmental Services Institute, and of its Risk21 steering group too, which Boobis also co-chairs.  In 2012, the ILSI group took a $500,000 donation from Monsanto and a $528,500 donation from the industry group Croplife International, which represents  Monsanto, Dow, Syngenta and others, according to documents obtained by the US right to know campaign. Boobis was not able to comment on the issue, and ILSI’s office in Washington […]

A Decade into the Pollinator Crisis, Unsustainable Bee Losses Continue

(Beyond Pesticides, May 17, 2016) It was 10 years ago that commercial beekeepers first reported widespread, unsustainable winter losses of their honey bee colonies. A decade after the alarm was first sounded on pollinator declines, results of 2015-16 Colony Loss Survey show no sign the crisis of abating. According to the Bee Informed Partnership survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. Beekeepers factor in that a small percentage, <15% of their colonies, will be lost each winter, but do not expect to lose colonies during the summer, when there is amble forage and nectar for bees. The costs beekeepers must incur to keep their hives alive continue to increase. More time and money is spent to maintain their hives, yet losses continue to be staggering ”” and unsustainable. As colony collapse disorder (CCD), the cryptic loss of honey bee colonies with no sign of dead bees in or around the hive, has faded from public discussion, concerns over pollinator declines in general, from bees […]

Study Finds Low Levels of Roundup Cause Adverse Effects to Soil Health

(Beyond Pesticides, May 13, 2016)  Raising questions about Roundup’s (glyphosate) effects on soil health, a study published last month shows that the chemical  is toxic to soil fungus at doses well below levels which are recommended for agricultural use. The commercial formulation of Roundup is  more toxic than technical active ingredient,  glyphosate, highlighting the need to evaluate  full formulation  effects, including  so-called inert ingredients. The study, published in Environmental Science and Pollution Research, looked at Roundup’s effects on  a soil fungus, Aspergillus nidulans. Researchers found that a dilution of Roundup at a rate 100 times less than that  allowed in agricultural production corresponded with 50% mortality of the fungus. A dose only 50 times lower than the recommended application rate for agricultural uses resulted in 100% mortality of the fungus. Even at the median lethal dose (LD50) and lower concentrations, researchers saw impaired growth, cellular polarity, endocytosis and mitochondria (impaired average number, volume and metabolism). The study also found that Roundup has an effect on the soil fungus’ ability to break down nutrients for energy use. Rather than depleting mitochondrial activity, as found in animal cell studies, researchers found a stimulation of mitochondrial activity in the fungal cells, indicating a […]

EPA Finds Atrazine Threatens Ecological Health

(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 […]

500,000 Petitioners Demand EPA End Glyphosate Use

(Beyond Pesticides, May 5, 2016) Yesterday, a large coalition of national organizations delivered over 500,000 petitions to EPA that demands an end to glyphosate use in the U.S. The groups held a rally outside the White House before marching over to EPA headquarters. The event, organized by Moms Across America and Care2, was also joined by Beyond Pesticides, Organic Consumers Association, Friends of the Earth, SumOfUs, and CREDO Action. Glyphosate  is a pervasive and toxic chemical found in Monsanto’s popular Roundup weedkiller and was classified by the  International Agency for Research on Cancer (IARC)  as a probable human carcinogen in 2015. This comes the week after news reports of the European Union indicating it  will re-approve glyphosate’s registration in the EU,  despite fierce public outcry, for another 10 years. Because EPA has not changed its classification of glyphosate as “not likely to be a carcinogen,” it is expected that  EPA will renew the registration  of glyphosate. (The report concluding that glyphosate is not likely  to be carcinogenic to humans was posted online  by EPA on Friday,  but taken down  the following Monday, pending the agency’s completion of its reevaluation.) “The current science confirms that glyphosate and Roundup are anything but […]

Pesticides Found in Turtles in Sequoia National Park

(Beyond Pesticides, April 29, 2016) Traces of pesticides, including the long-banned organochlorine chemical DDT, have been found in Western pond turtles, insects, and soil sediment at Sequoia National Park, according to a study.  The study, entitled Organic contaminants in western pond turtles in remote habitat in California  and published in the journal Chemosphere, surveys a suite of 57 current- and historic-use pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in the western pond turtle, along with their potential prey items and habitat. California study sites include Sequoia National Park, Whiskeytown National Recreation Area, and Six Rivers National Forest, all of which are downstream of undeveloped watersheds and varied in distance from agricultural and urban pollution sources. Researchers found that organic pollutants are widespread in the western pond turtle, which has conservation status; that pesticides are prominent in Sequoia National Park, which is downwind of heavy agriculture; and that the legacy  pesticides and PCB concentrations indicate that bioaccumulation is occurring. Brian Todd, Ph.D., an associate professor of wildlife, fish, and conservation biology at University of California Davis, co-authored the study. Dr. Todd said controlling the flow of pesticides into national parks is pretty much impossible. “Sequoia National Park is very […]

(Beyond Pesticides, April 26, 2016) A study published last month finds that exposure to endocrine-disrupting chemicals (EDC) plays an important role in the development of certain female reproductive disorders, and ultimately results in significant economic costs to society. The study, published in the Journal of Clinical Endocrinology &nMetabolism, and authorized by a team of scientists from New York University School of Medicine and Washington State University’s School of Molecular Biosciences, looked at the monetary impact of EDC-attributed female reproductive disorders in the European Union (EU). This economic valuation is part of series of analyses undertaken by the research team, which determined last year that over €150 billion ($162 billion) in yearly health care costs in the EU are attributable to the loss of brain function induced by EDCs. “There are substantial human and toxicological studies (in mice and other lab animals) that suggest that exposure to these endocrine-disrupting chemicals, many of which are increasing in use, are contributing to female reproductive conditions,” said study co-author Leonardo Trasande, MD, associate professor of pediatrics at NYU School of Medicine to CNN. The study found that the strongest data linking EDCs to female reproductive disorders was exposure to diphenyldichloroethene (DDE) resulting in fibroids, […]
