Groups File Endosulfan Lawsuit Against EPA

Friday, July 25th, 2008

(Beyond Pesticides, July 25, 2008) San Francisco, California —  On July 24, 2008,  a broad coalition of farmworker, public health, and environmental groups filed a lawsuit against the Environmental Protection Agency (EPA) to stop the continued use of a hazardous pesticide called endosulfan. The coalition is demanding action from EPA to protect children, farmworkers, and endangered species. Endosulfan is an organochlorine, part of the same family of chemicals as DDT, which EPA banned in 1972. Like other organochlorine pesticides, endosulfan is persistent in the environment and poisons humans and wildlife both in agricultural areas and in regions far from where it was applied. “This dangerous and antiquated pesticide should have been off the market years ago,” said Karl Tupper, a staff scientist with Pesticide Action Network. “The fact that EPA is still allowing the use of a chemical this harmful shows just how broken our regulatory system is.” Acute poisoning from endosulfan can cause headaches, nausea, vomiting, convulsions, and in extreme cases, unconsciousness and even death. Studies have linked endosulfan to smaller testicles, lower sperm production, and an increase in the risk of miscarriages. One glaring omission in the EPA’s decision is its failure to consider risks to children. A […]

Capsized Ferry in Philippines Holds Ten Tons of Toxic Pesticide

Monday, July 7th, 2008

(Beyond Pesticides, July 7, 2008) Officials have halted recovery efforts in the Philippines for bodies on the partially sunken ship MV Princess of the Stars after it was revealed that the ship’s cargo hull contains ten tons of the highly toxic pesticide endosulfan. The ship capsized and partially sank on June 21 in a typhoon, killing nearly 800 people onboard. Although the Philippines banned the use of endosulfan in 1993 because of its serious health effects, multi-national food companies Dole and Del Monte have maintained exemptions to the ban and continue to use endosulfan. In the wake of this tragedy, the potential for toxic contamination looms large and has raised frustrations for leaders in the government who are calling for an end to these exemptions, which benefit only foreign companies and threaten the health of the Philippine people. Globally, endosulfan has received substantial attention for its severe health and environmental effects. The European Union has submitted a petition that endosulfan be included in the Stockholm Convention, the international treaty regulating highly toxic, persistent organic pollutants. Endosulfan is banned in over 20 countries, including those of the European Union. Despite its known toxicity, endosulfan remains a commonly used insecticide and acaricide […]

Organochlorine Pesticide Linked to Behavioral Deficit in Infants

Thursday, May 29th, 2008

(Beyond Pesticides, May 29, 2008) A study published in the May issue of Environmental Health Perspectives shows a link between prenatal exposure to the pesticide DDT and poor attention-related skills in early infancy. This study follows in a long line of recent studies associated with the negative health effects of DDT including: diabetes; non-Hodgkin lymphoma; breast cancer; and autism. Despite the fact that DDT was banned in the U.S. in 1972, concentrations of this toxic chemical’s major metabolite, DDE, have remained alarmingly high in many ecosystems, including the waters of Los Angeles County, the arctic, and even U.S. national parks. All studies documenting the health effects of DDT and chemicals in the same family, organochlorines, are particularly important not just for understanding the lingering effects of DDT from days past, but because many countries continue to employ DDT as a method in controlling mosquitoes that transmit malaria, despite its toxicity, weakening efficacy, and availability of safer alternatives. Other organochlorines are still registered for use in the U.S.The study looked at 788 mother-infant pairs who met several criteria, which included living in a town adjacent to a Superfund site in New Bedford, Massachusetts, a location with known organochlorine contamination. Cord blood […]

Scientists and Activists Urge EPA to Ban Endosulfan

Tuesday, May 20th, 2008

(Beyond Pesticides, May 20, 2008) On May 19, 2008, scientists, Arctic tribal governments and Indigenous groups and environmental health advocates sent letters calling on the Environmental Protection Agency (EPA) to phase out the organochlorine pesticide endosulfan.“It is time to take this dangerous and antiquated pesticide off the market,” says Jennifer Sass, Ph.D., a senior scientist with the Natural Resources Defense Council. “The scientific evidence clearly shows that the continued use of this chemical puts the health of exposed farmworkers, communities and the environment at risk.” Dr. Sass is one of over 55 international scientists, medical doctors, nurses, and other health professionals urging EPA to take action on endosulfan in a letter to Administrator Stephen Johnson. Prominent scientists endorsing the letter include Philip Landrigan, M.D., M.Sc., a pediatrician and Director of the Center for Children’s Health and the Environment at the Mount Sinai School of Medicine and Ronald Herberman, M.D. and Devra Davis, Ph.D., M.P.H., researchers at the University of Pittsburgh Cancer Institute. Used in the U.S. on tomatoes, cotton and other crops, endosulfan harms the hormone system, and low levels of exposure in the womb have been linked to male reproductive harm, other birth defects and possibly autism. Acute poisoning […]

USGS Identifies Contaminants in Potomac River Possibly Linked to Intersex Fish

Monday, March 24th, 2008

(Beyond Pesticides, March 24, 2008) Scientists at the U.S. Geological Survey (USGS) announced that they have identified ten contaminants, including pesticides, in the Potomac River, which flows through downtown Washington, DC, that could be responsible for the alarming discovery of “intersex fish,” male fish producing eggs. The suspected chemicals include: atrazine, a common herbicide used in agriculture and on lawns that is already linked to sexual abnormalities in frogs; insecticides chlorpyrifos and endosulfan; the herbicide metolachlor; and two chemicals used to add fragrance to perfumes, soaps and other products, tonalide and galaxolide. To collect the samples, USGS scientists suspended a device intended to serve as a facsimile fish in the Potomac River near the Washington, DC’s Blue Plains sewage plant. The device had a plastic-coated tube, which simulated a fish’s permeable skin, and a layer of simulated fat. According to the Washington Post, the tests on this fake fat revealed a range of potentially worrisome pollutants. Most have been found in other streams around the U.S. “The types of things we’re finding are the types of things that are associated with everyday life,” David Alvarez, a U.S. Geological Survey research chemist who analyzed samples from the Potomac told the Washington […]

Bird Eggs Found to Contain Chemical Contaminants

Wednesday, March 12th, 2008

(Beyond Pesticides, March 12, 2008) BioDiversity Research Institute, a nonprofit ecological research group, released a new report that was presented March 12, 2008 to Maine’s Joint Standing Committee on Natural Resources. Entitled “Contaminant Screening in Maine Birds,” it documents over 100 harmful contaminants that were found in Maine bird eggs. Scientists collected 60 eggs, representing 23 species of birds, all of which test positive for chemical contaminants, some at levels believed to be harmful to the birds. Flame retardants (PBDEs), industrial stain and water repellants (PFCs), transformer coolants (PCBs), pesticides (OCs), and mercury are found in all 23 species of birds tested. The bird species studied live in a variety of habitats: on Maine’s ocean, salt marshes, rivers, lakes and uplands. “This is the most extensive study of its kind to date and the first time industrial stain and water repellants were discovered in Maine birds,” says report author, senior research biologist Wing Goodale with the Institute. The Common loon, Atlantic puffin, piping plover, belted kingfisher, great black-backed gull, peregrine falcon and bald eagle have the highest contaminant levels. The flame retardant deca-BDE, banned last year in Maine, is found in eight species. Overall, eagles carry the greatest contaminant load, […]

Action Alert: Tell EPA to Cancel Endosulfan!

Friday, February 8th, 2008

(Beyond Pesticides, February 8, 2008) The Environmental Protection Agency (EPA) is asking for public input on its review of the chemical endosulfan, an antiquated and dangerous insecticide. Now is the time to go on record to protect children, farmworkers and rural communities from this harmful nerve toxin. Used in the U.S. on tomatoes, cotton and other crops, endosulfan harms the hormone system, and low levels of exposure in the womb have been linked to autism, male reproductive harm, and other birth defects. Acute poisoning can cause headaches, nausea, vomiting, convulsions, and in extreme cases, unconsciousness and even death. EPA’s own analysis shows that endosulfan endangers workers who handle it directly and those who work in endosulfan-treated fields. Endosulfan travels great distances, accumulates up the food chain, and poses grave risks to aquatic ecosystems. The European Union and several other countries have already banned endosulfan, and alternatives are available. It’s time the U.S. does its part to protect communities and the environment at home and around the world from this persistent organic pollutant. TAKE ACTION: Let EPA know that continued use of this unnecessary poison is unacceptable. Add your name to the petition today and forward to as many people as […]

IIT Scientists Use Nanoparticles To Filter Organochlorines from Water

Monday, January 14th, 2008

(Beyond Pesticides, January 14, 2008) Researchers at the Indian Institute of Technology (IIT) Madras have developed nanoparticles that can remove organochlorine pesticides from drinking water. These chemicals are quite persistent in the environment and difficult to remove from water. Notorious organochlorines include DDT, endosulfan, HCH (hexacholorcyclohexane) and aldrin, all of which have known health and/or environmental hazards. Many of these chemical pesticides are used heavily in agriculture and taint India’s water. Though no comprehensive national survey has been done, isolated studies show contamination of groundwater and river systems that cannot be removed by standard water filters. “Even though some of these pesticides have been banned, they are very much present in the environment. For instance, endosulfan has an environmental lifetime of 100 years,” said Thalappil Pradeep, professor of chemistry at IIT Madras. He leads the research that has shown that nanoparticles, mostly from gold, silver, copper and several oxides, are effective at removing endosulfan even at very low concentration. “Efficient chemistry at low concentration is important so that even if one molecule of the pesticide passes by, it gets removed by the nanoparticle,” said Pradeep. He holds a US and an Indian patent and has licensed part of the technology […]

Christmas Tree Pesticide Use Down, But Still Used by Most Growers

Tuesday, November 27th, 2007

(Beyond Pesticides, November 27, 2007) While there is a trend towards less pesticide use in Christmas tree production, most trees are still treated with one pesticide or another — many of which are prohibited for residential use. In it’s 2007 survey results, North Carolina State University’s Mountain Horticultural Research and Extension Center, reports that glyphosate was the pesticide applied most commonly. The Center found that almost 90 percent of the state’s tree growers had applied glyphosate last season. The following tables summarize the state’s results, listing the pesticides that are used on at least 5% of the Christmas tree acreage. Nearly 40 different active ingredients are registered for tree production nationwide. Oregon, North Carolina, Michigan, Pennsylvania, Wisconsin, Washington, New York, and Virginia are the nation’s top Christmas tree producing states. Pennsylvania’s Department of Agriculture, which published a list of insecticides for Christmas tree production in February 2007, recommends carbaryl, carbofuran, chlorpyrifos, diazinon, endosulfan, imidacloprid, malathion, permethrin and many more. Many of these pesticides have been “banned” or have always been prohibited in residential settings, however EPA’s registration process and phase-out deals with manufacturers allows continued use on Christmas trees and other agricultural products. For information on the toxicity of these […]

Pesticides Linked to Rising Autism Rates

Tuesday, November 13th, 2007

November 13, 2007) Autism is on the rise, both in prevalence and incidence, and there is growing evidence that environmental insults, such as pesticides, are linked to this developmental disability. According to the latest study, published in the October issue of Environmental Health Perspectives, children born to mothers living near fields where pesticides are applied are more likely to develop autism spectrum disorders (ASDs). The authors of “Maternal Residence Near Agricultural Pesticide Applications and Autism Spectrum Disorders among Children in the California Central Valley” compared maternal pesticide exposure for 465 children with ASDs and 6,975 children without ASDs living in the same area. The research reveals that mothers who lived within 500 meters of fields sprayed with organochlorine pesticides, specifically endosulfan and dicofol, during their first trimester of pregnancy had a six times higher chance of having children with autism compared to mothers who did not live near the fields. Mark Horton, M.D., director of the California Department of Health, said the findings are exploratory and indicate that more research of the relationship between organochlorines and ASDs is needed. (See Daily News Blog posting from July 31, 2007 for further reactions from health care officials and more details about this […]

Potential Link Between Autism and Pesticide Exposure

Tuesday, July 31st, 2007

(Beyond Pesticides, July 31, 2007) Preliminary research into birth records and pesticide data reveal that mothers who were within 500 meters of fields sprayed with organochlorine pesticides during their first trimester of pregnancy were six times higher to have children with autism compared to mothers who did not live near the fields. Scientists from the California Department of Public Health conducted the study, which is available online in Environmental Health and Perspectives, entitled, “Maternal Residence Near Agricultural Pesticide Applications and Autism Spectrum Disorders Among Children in the California Central Valley.” The study, initiated to “systemically explore the general hypothesis that residential proximity to agricultural pesticide applications during pregnancy could be associated with autism spectrum disorders in offspring,” found that 28% of the mothers studied who lived near fields in Central Valley, which were sprayed with organochlorines, such as endosulfan and dicofol, have children with autism. However, officials are quick to point out that their findings are preliminary. “We want to emphasize that this is exploratory research,” says Dr. Mark Horton, M.D., director of the California Department of Health. “We have found very preliminary data that there may be an association. We are in no way concluding that there is a […]

Climate Change and Pesticides Hot Issue for Fish

Monday, July 23rd, 2007

(Beyond Pesticides, July 23, 2007) New research finds several species of freshwater fish have lower temperature tolerances when exposed to the widely used pesticides endosulfan and chlorpyrifos. The discovery reveals another key pesticides issue in the global warming debate. The study, “The Effects of Three Organic Chemicals on the Upper Thermal Tolerances of Four Freshwater Fishes” (Environmental Toxicology and Chemistry, July 2007), is the work of Ronald Patra of Australia’s Department of Environment and Conservation and colleagues. The study establishes the upper temperature tolerances of both unexposed and exposed silver perch, eastern rainbowfish, western carp gudgeon and rainbow trout. Exposed fish were given sublethal doses of endosulfan, chlorpyrifos or phenol. The results show exposure to endosulfan cause a decrease of temperature tolerance in silver perch by 2.8 °C, eastern rainbowfish 4.1 °C, western carp gudgeon 3.1 °C, and rainbow trout 4.8 °C. Chlorpyrifos decreases temperature tolerance in silver perch by 3.8 °C, eastern rainbowfish 2.5 °C, western carp gudgeon 4.3 °C, and rainbow trout 5.9 °C. Phenol is not shown to cause a significant decrease in tolerance. The authors conclude, “The reduction in thermal tolerance of fish in the presence of endosulfan and chlorpyrifos suggest that, not only does temperature […]

Seafood From Southern China Contaminated by Organochlorine Pesticides

Tuesday, May 22nd, 2007

(Beyond Pesticides, May 22, 2007) In a study published in the latest issue of Environmental Toxicology and Chemistry, scientists found that seafood products from southern China contain high concentrations of DDT and hexachlorocylohexane (HCH). While banned in China since 1983, humans are being exposed to organochlorine pesticides (OCP) at rates high enough to pose health threats. The study responded to high rates of DDT and HCH found in sediment, water and biota in the Pearl River delta and neighboring coast, where land is being rapidly industrialized, urbanized, and transferred from agriculture to commercial development. Researchers tested 212 seafood products, including shrimp, crabs, and mollusks, from 11 coastal cities for 21 OCPs, including DDT, HCH, heptachlor, dieldrin, and endosulfan. The highest concentrations of DDT were found in four species of shellfish, although concentrations varied widely depending on sampling location. The study reported, “These results suggest that bioaccumulation of DDTs in seafood products was highly species-specific, probably due to different feeding habits and habitats.” By taking a large sample of one indicator species, it also concluded “the coastal region of southern China is probably one of the most DDT-polluted areas in the world.” Researchers also found HCH to be more widely prevalent […]

Chemical Estrogen-Mimics Impact Asthma, Immune Functioning

Tuesday, April 10th, 2007

(Beyond Pesticides, April 10, 2007) Scientists have reported several environmental estrogens can affect the immune system, promoting allergic diseases such as asthma. Researchers have observed this response using pesticides and other environmental contaminants. Focusing on six environmental estrogens (xenoestrogens), researchers were able to reveal how these contaminants affect the immune system. Using doses representative of present human exposures, these estrogen-mimics were tested on human and mouse cells. The observed effect of exposure was both an increase in speed and intensity of immune reactions. Three of the environmental estrogens tested were organochlorine pesticides or metabolites: endosulfan, dieldrin and DDE (DDT metabolite). The other contaminants included nonylphenol, a by-product of plastics manufacturing, and two PCBs. The study reveals that the accelerated and increased level of degranulation of mast cells is the mechanism that causes more severe allergic reactions than would otherwise take place. According to Environmental Health News, mast cells play a vital role in allergic reactions because they are primed by past experience with allergens to release inflammatory agents into the body, which causes an allergic reaction. If the mast cell has been primed to react to a specific allergen, it will degranulate, releasing molecules such as histamine. The more intense […]

New Pesticides Added to Toxic Trade List

Friday, March 30th, 2007

(Beyond Pesticides, March 30, 2007) A committee of experts advising the United Nations Environment Programme and the Food and Agriculture Organization (FAO) has recommended adding endosulfan and tributyl tin compounds (TBT) to a list of substances that are considered so harmful they can only be traded in special circumstances. On March 27, 2007, the United Nations said that the toxic chemicals would only be allowed to be exported to countries that have explicitly chosen to permit them, a measure aimed at protecting humans and the environment in developing countries. Endosulfan, a chemical sprayed onto food crops and cotton, and TBT, used in “antifouling paint” for ships’ hulls, are already banned in many countries. However, they may be traded freely in countries lacking tight environmental regulations. According to David Santillo who works at the research center for Greenpeace at Britain’s Exeter University, “It’s great that these two have been added to the list so countries have the choice whether to import them or not.” Endosulfan has been linked with testicular cancer, prostate cancer, breast cancer, and defects in male sex organs. According to a recent study conducted in Costa Rica’s mountain forests, findings show that surprisingly high concentrations of pesticides are […]

Honeybees Vanish, Threatening Crops and Livelihoods

Thursday, March 1st, 2007

(Beyond Pesticides, March 1, 2007) In 24 states throughout the country, beekeepers have been shocked to find that bees have been inexplicably disappearing at an alarming rate, according to an article in the New York Times last week. This loss of honeybees threatens not only beekeeper livelihoods but also the production of numerous crops, including California almonds, one of the nation’s most profitable crops. Although the reasons for the honeybee disappearances are unknown, pesticides may be one of the culprits. “I have never seen anything like it,” David Bradshaw, a California beekeeper, said. “Box after box after box are just empty. There’s nobody home.” Last month he discovered that half of his 100 million bees were missing. Beekeepers have fought regional bee crises before, but this is the first national affliction. Bees are flying off in search of pollen and nectar and simply never returning to their colonies. And nobody knows why. Researchers say the bees are presumably dying in the fields, perhaps becoming exhausted or simply disoriented and eventually falling victim to the cold. As researchers scramble to find answers to the syndrome they have decided to call “colony collapse disorder,” growers are becoming openly nervous about the capability […]

Research Shows Pesticide Accumulation at High Altitudes

Thursday, January 18th, 2007

(Beyond Pesticides, January 18, 2007) A new study conducted in Costa Rica’s mountain forests indicates that surprisingly high concentrations of pesticides are accumulating far above the low altitudes at which they are used. Previously thought to be safe from pesticides applied to distant agricultural areas, some remote mountain forests of Costa Rica were found to have pesticide levels almost ten times greater than those in low-lying areas closer to farms and plantations. The study, led by University of Toronto, Scarborough professor Frank Wania, Ph.D., measured air and soil pesticide levels at 23 sites across Costa Rica in order to produce a model to predict potential accumulation of chemicals at high altitudes. The insecticide endosulfan and the fungicide chlorothalonil were found in the largest concentrations, with up to 1 part per billion (ppb) of chlorothalonil and 3 ppb endosulfan in soil. The high concentrations can be explained by a process in which polluted air above the farms and plantations is pushed up into the mountains, where it then cools and becomes polluted rainwater or fog. The hydrophilic nature of modern pesticides makes the occurrence of this phenomenon much more likely; as Crispin Halsall, Ph.D., of Lancaster University (U.K.) explains, “Most currently […]
