(Beyond Pesticides, March 30, 2010) Searching for clues to the mysterious disappearance of bees, known as “colony collapse disorder”(CCD), Penn State University researchers have identified widespread pesticide contamination of beehives. The study, “High Levels of Miticides and Agrochemicals in North American Apiaries: Implications for Honey Bee Health,” was published March 19, 2010 in the scientific journal Public Library of Science (PLOS). The study finds 121 different types of pesticides within 887 wax, pollen, bee and hive samples from 23 states. The top 10 most frequently detected pesticides are fluvalinate, coumaphos, chlorpyrifos, chlorothalonil, amitraz, pendamethalin, endosulfan, fenpropathrin, esfenvalerate and atrazine. Miticides are the most common contaminant in the wax and bees, and fungicides are the most common contaminant of pollen. For the full results of the study, including several tables of wax, pollen and bee sample data, download the study from the PLOS website. “The pollen is not in good shape,” Chris Mullin, PhD, lead author of the study, told Discovery News. The authors state that the 98 pesticides and metabolites detected in mixtures up to 214 parts per million (ppm) in bee pollen alone represents a remarkably high level for toxicants in the brood and adult food of this primary […]

(Beyond Pesticides, March 26, 2010) A new study by researchers at Columbia University’s Mailman School of Public Health has linked exposure to the insecticide chlorpyrifos to early childhood developmental delays. Chlorpyrifos is a broad spectrum organophosphate insecticide that was banned for household use in 2001, but is still widely used in agriculture. The study, entitled “Chlorpyrifos Exposure and Urban Residential Environment Characteristics as Determinants of Early Childhood Neurodevelopment,” was published online and will be published in print in the may issue of the American Journal of Public Health. The study examined 266 children born between 1998 and 2002 living in low income neighborhoods of the South Bronx and Northern Manhattan in New York City. Before being banned chlorpyrifos was widely used in these areas. Of the children studied, 47% were male, 59% were Dominican and 41% were African American. Researchers compared motor and mental development to levels of exposure to the pesticide at birth. They found that high concentrations of chlorpyrifos in umbilical cord blood (>6.17 pg/g) corresponds to a 6.5 point decrease in the Psychomotor Development Index, and a 3.3 point decrease in the Mental development index in 3 year olds. Previous research published in 2006 on the same […]

(Beyond Pesticides, March 25, 2010) A new study finds that the absence of a maximum dose on some household pesticides labels leave consumers with the impression that “if a little is good, more is better.” According to the study that was presented at the 239th National Meeting of the American Chemical Society (ACS), label directions are written in a way that may result in consumers using excessive amounts of pesticides, subjecting their family and pets to increased exposures. The new study, which was lead by California Environmental Protection Agency researcher Linda M. Hall, Ph.D., and her colleagues, finds that while minimum and maximum doses are clearly listed on labels for agricultural pesticides, labels for some household pesticides, such as para-dichlorbenzene (pDCB) mention the minimum amount for consumers to use but do not indicate the maximum. Para-dichlorobenzene (pDCB) is the active ingredient in mothballs and other products used to protect silk, wool, and other natural fibers against moths and beetles; caged birds against lice and mites; mildew prevention; and is also used in air fresheners and bathroom deodorizers. Exposure to moth repellents, which include other toxic chemicals such as naphthalene and camphor, can cause eye and respiratory irritation, headaches, confusion and […]

(Beyond Pesticides, March 24, 2010) Due to a significant increase in adverse incidents, the U.S. Environmental Protection Agency (EPA) is taking a series of actions aimed at increasing the safety of spot-on pesticide products for flea and tick control for cats and dogs. EPA will begin reviewing labels to determine which ones will require new instructions and labeling for on-spot flea products. EPA began investigating the products after discovering a sharp rise in the number of dogs and cats reported to be sick. Incidents reported by consumers rose from 28,895 in 2007 to 44,263 in 2008, an increase of 53 percent. The products investigated, including the popular Frontline and Advantage brands, are small vials of liquid pesticides that pet owners apply monthly to the backs of dogs or cats to kill fleas and ticks. EPA began investigating the products after discovering a sharp rise in the number of pets reported to be sick after they were treated. The year long investigation, conducted by a team of veterinarians assembled by the agency, concluded that certain pets — small dogs between 10 and 20 pounds — are most susceptible to the problems, which include rashes, vomiting, diarrhea and seizures. EPA plans to […]

(Beyond Pesticides, March 12, 2010) Over 40 million Americans watched Sandra Bullock and Jeff Bridges win the best actress and actor Oscars at the 82nd Academy Awards last Sunday. On Wednesday March 3rd, Californians for a Healthy and Green Economy (CHANGE) recognized the year’s bad actors, bad chemical actors that is, at the first ever “Toxies.” CHANGE is a coalition of environmental, policy, labor, interfaith and other organizations working to regulate toxic chemicals in the state of California. Held at the Egyptian Theater in Hollywood, the Red Carpet Event featured actors in character as various harmful chemicals. Toxies were awarded to the pesticides Triclosan and Methyl Iodide. The tongue-in-cheek award show was intended to bring awareness to the harmful effect that these chemicals have on human health and the environment. The timing coincides not only with the awards show season, but with the anticipated release of the final draft of regulations for California’s Green Chemistry Programs. The awards ceremony and accompanying report awarded Toxies to 16 bad chemical actors. The “winners” all affect human health and all have safer alternatives. The 2010 Toxie winners are: Worst Breakthrough Performance: Bisphenol A (BPA) Found in plastics BPA has been linked to breast […]

(Beyond Pesticides, March 11, 2010) The New York State Department of Environmental Conservation (DEC) determined that a pair of bald eagles were killed and a host of other wildlife were injured after an Allegany County farmer applied a highly toxic pesticide that has been canceled for use by the U.S. Environmental Protection Agency (EPA). Following an investigation, the state DEC determined that the two bald eagles were poisoned after ingesting the improperly applied pesticide Furadan, or carbofuran, on his farm. The farmer and landowner, Richard Sekoll, was charged with and pleaded guilty to violating state pesticide laws and fish and wildlife laws and paid $3,000 in fines. After receiving a call that two dead bald eagles were found near the Genesee River last fall, DEC began an investigation and sent the eagles to the department’s Wildlife Pathology Unit. Lab results showed that the birds died of poisoning from consumption of carbofuran, which occurred after the eagles consumed prey that had ingested the pesticide. State officials with the DEC’s Division of Pesticides and the Division of Wildlife, as well as the U.S. Fish and Wildlife Service assisted in the investigation, which found that a farm within 500 yards of where the […]

(Beyond Pesticides, March 10, 2010) A study investigating the sublethal effects of pyrethroids, bifenthrin and deltamethrin on honeybees finds that the chemicals significantly impair the pollinators’ reproduction. The researchers also point out that the concentration of each pesticide that produced adverse effects in the experiments was at or below those that bees could encounter while pollinating treated crop fields. “Effects of sublethal concentrations of bifenthrin and deltamethrin on fecundity, growth, and development of the honeybee Apis mellifera ligustica” published in the March issue of Environmental Toxicology & Chemistry, investigated the effects of the two pesticides at sublethal concentrations on fecundity, growth, and development of honeybees were examined with the feeding method for a three-year period (2006-2008). It was shown that both bifenthrin and deltamethrin significantly reduced bee fecundity, decreased the rate at which bees develop to adulthood, and increased their immature periods. Queens in the control group in 2006 laid a little more than 1,200 eggs each day, compared to not quite 900 a day in the bifenthrin group and roughly 600 per day in the deltamethrin group. In general, the hatch rate of pyrethroid-exposed eggs was also significantly depressed. The success rate of hatchlings, that is the share that […]

(Beyond Pesticides, March 8, 2010) Twenty local businesses and organizations around New Brunswick, New Jersey announced their commitment to not purchase, use or sell products that contain triclosan, an antimicrobial pesticide shown to pose risks to both human health and the environment. Last week, the national consumer advocacy group Food & Water Watch convened an event with the businesses and organizations as part of its “Wash Your Hands of Triclosan” campaign. Speakers additionally expressed support for a proposed Highland Park ordinance to ban the municipal purchase of products containing triclosan, which will be discussed at the Highland Park Board of Health’s meeting on March 11. The community support behind prohibiting triclosan products is a strong indication of an increasing public rejection of the chemical. Originally developed as an anti-bacterial agent for hospital settings, triclosan is widely found in many consumer and household products ranging from dish soaps and detergents to toothpastes, deodorants, and others. A known endocrine disruptor, triclosan has been linked to antibiotic resistance, and can affect male and female reproductive hormones, which could potentially increase risk for cancer. Due to its prevalence in so many products, triclosan is now showing up in many things, from human breast milk […]

(Beyond Pesticides, March 3, 2010) A recently published study in the Proceedings of the National Academy of Sciences finds that male frogs exposed to the herbicide atrazine can become so completely female that they can mate and lay viable eggs. This latest study adds to the growing scientific evidence which shows that atrazine, one of the most common herbicides used in the U.S., disrupts the development and behavior of aquatic animals, and negatively effects their immune, hormone, and reproductive systems. The study, “Atrazine induces complete feminization and chemical castration in male African clawed frogs (Xenopus laevis),” led by Tyrone Hayes, PhD, at the University of California, Berkeley, demonstrates the reproductive consequences of atrazine exposure in adult amphibians. Dr. Hayes and other researchers examined a group of 40 African clawed frogs, all of which carried male chromosomes. As tadpoles, the frogs were put in water with 2.5 parts per billion (ppb) of atrazine — a concentration within federal drinking water standards. Atrazine-exposed males were both demasculinized (chemically castrated) and completely feminized as adults. Exposed genetic males developed into functional females that copulated with unexposed males and produced viable eggs. The eggs produced were all male offspring since both parents contributed male […]

(Beyond Pesticides, February 24, 2010) On February 22, 2010 the U.S. Food and Drug Administration (FDA) issued a federal notice requesting data and information regarding the potential environmental impact of triclosan’s use in acne and antiplaque/antigingivitis products. The agency, in order to comply with the National Environmental Protection Act (NEPA), must complete environmental assessments (EA) for active ingredients before they are included in the agency’s over-the-counter (OTC) drug regulation system. Triclosan, a controversial antibacterial agent found in hundreds of consumer products, from hand sanitizers to toys, is one of 13 chemicals being assessed by FDA for environmental impacts according to their proposed uses. According to FDA regulations, the agency must conduct EAs before chemicals are approved for use in OTC drug products. In this case, triclosan is being considered for use in acne and antiplaque/antigingivitis products. Even though this action is being taken, FDA has never been able to finalize and approve the use of triclosan in any OTC products, despite the proliferation of these products in the consumer marketplace. It appears that EAs for the vast majority of triclosan uses have been completed. Other FDA regulations on triclosan have not been updated since 1994 and much of the data […]

(Beyond Pesticides, February 22, 2010) Wives of agricultural pesticide applicators have a significantly increased risk of developing thyroid disease, according to the new study, “Pesticide Use and Thyroid Disease Among Women in the Agricultural Health Study,” published in the American Journal of Epidemiology. Using data collected from more than 16,500 female spouses from Iowa and North Carolina enrolled in the Agricultural Health Study from 1993 to 1997, the researchers show that 12.5 percent of the women have thyroid disease, 6.9 percent have hypothyroidism and 2.1 percent have hyperthyroidism; whereas, the national average is 5 percent and 1 percent, respectively. Thyroid disease is more common in women than men and is the second most common hormone disorder affecting women of childbearing age. According to the study results, ever use of a fungicide shows a slight increased risk (odds ratio (OR) 1.4) and ever use of an organochlorine insecticide shows a 1.2 OR for hypothyroidism. Ever use of the fungicide benomyl shows a more than tripling of risk to hypothyroidism, whereas the fungicides maneb and mancozeb show a more than doubling and the herbicide paraquat shows a nearly doubling of risk. Maneb and mancozeb also show a more than doubling of risk […]

(Beyond Pesticides, February 18, 2010) Hundreds of dead and dying lobsters just north of the Gulf of Maine were found to have been exposed to cypermethrin, a highly toxic synthetic pyrethroid pesticide registered for agricultural and residential use that some officials think may have been illegally used in fish farming. However, the chemical, which is primarily used for indoor insect control and termites, is extremely toxic to fish and aquatic organisms and part of a family of pesticides (synthetic pyrethroids) that is increasingly showing up in water bodies at toxic levels, a cause for concern according to scientists. Area fisherman are angry and concerned, however investigators are not yet certain just how this pesticide wound up in the Bay of Fundy, which is located between the Canadian provinces of Nova Scotia and New Brunswick. The first dead lobsters were discovered last fall in Grand Manan’s Seal Cove, and only a few days later fisherman found dead lobsters in two different locations in the Bay, including about 816 kilograms of dying or dead lobsters in Deer Island’s Fairhaven Harbour. This prompted an investigation by Environment Canada that began on December 22, 2009. The department looked at samples of crab, kelp, mussels […]

(Beyond Pesticides, February 17, 2010) In the largest study of its kind, researchers searched hundreds of Salinas Valley, California homes for pesticide compounds sticking to dust layers and discovered widespread residues of 22 residential and agricultural-use products. The study, “Pesticides in Dust from Homes in an Agricultural Area,” was conducted by an investigator from the California Department of Public Health and researchers with the Center for the Health Assessment of Mothers and Children of Salinas (CHAMACOS) with the University of California, Berkeley. CHAMACOS began recruiting pregnant women in the Salinas Valley for a long-term study of prenatal and infant chemical and allergen exposure in 1999. The center sampled study homes in 1999 and 2000 with a modified vacuum cleaner. The most common pesticides found were permethrin (467ppb) -a popular insecticide against home insect, and chlorpyrifos (74ppb). The U.S. Environmental Protection Agency (EPA) banned chlorpyrifos for home-use in 2000, but it is still used in agriculture. Other pesticides frequently detected include the herbicide dimethyl tetrachloroterephthalate (DCPA), methomyl, diazinon and a fungicide, iprodione. Household dust concentrations are significantly associated with nearby use of these chemicals on agricultural fields in the month or season prior to sample collection. The study reported that in […]

(Beyond Pesticides, February 16, 2010) Pyrethroids, among the most widely-used home pesticides, are winding up in California rivers at levels toxic to some stream-dwellers, possibly endangering the food supply of fish and other aquatic animals, according to a study by researchers at the University of California, Berkeley, and Southern Illinois University (SIU). The study, “Urban and Agricultural Sources of Pyrethroid Insecticides to the Sacramento-San Joaquin Delta of California,” in the journal Environmental Science & Technology, is the first published work to document toxic levels in the water column as well as in the sediments at the bottom of streams. Pyrethroid insecticides, commonly used to kill ants and other insects around the home, have been found in street runoff and in the outflow from sewage treatment plants in the Sacramento, California area. The insecticide ended up in two urban creeks, the San Joaquin River and a 20-mile stretch of the American River, traditionally considered to be one of the cleanest rivers in the region. Although the pyrethroid levels were low, around 10-20 parts per trillion, they were high enough to kill a test organism similar to a small shrimp that is used to assess water safety. “These indicator organisms are ‘lab […]

(Beyond Pesticides, February 12, 2010) The Washington Post is reporting that after much protest from environmentalists, farmers, doctors, and state officials, India has imposed a moratorium on a genetically engineered (GE) variety of brinjal or eggplant. Bacillus thuringiensis (Bt) brinjal has been engineered to produce its own insecticide. It would have been India’s first GE food crop, and the world’s first GE eggplant approved for wide scale production. Bt cotton is currently India’s only genetically modified crop. Bt corn is grown in 17 countries including the United States, and China recently approved a strain of Bt rice for human consumption. A government committee approved the commercial release of Bt brinjal in October. The committee’s decision was met with protests across the country. The states of Uttarakhand, Himachal Pradesh, and Karnataka had already stated their intention to ban the crop if the federal government approves it. When Environment Minister Jairam Ramesh hosted seven public meetings around the country to debate Bt Brijal, some meetings devolved into heated shouting matches. Many protesters dressed as bright purple or green eggplants. Mr. Ramesh has since called for more independent research to ensure the crop is safe for human consumption, saying the moratorium will continue […]

(Beyond Pesticides, February 10, 2009) Living near farms that use the weed killer atrazine increases the risk of a rare birth defect, according to a study presented February 5, 2010 at the annual meeting of the Society for Maternal-Fetal Medicine in Chicago. Gastroschisis, a rare birth defect in which an infant’s intestines stick out of the body through a defect on one side of the umbilical cord, affects 1 in 5000 babies born in the U.S. each year. Babies with this condition have problems with movement and absorption in the gut, because the unprotected intestine is exposed to irritating amniotic fluid. Surgery is required to repair this defect. The rate of gastroschisis has risen 2- to 4-fold over the last three decades, especially in areas where agriculture is the primary industry, according to Sarah Waller, PhD, of the University of Washington, Seattle, and colleagues. Dr. Waller’s team studied the potential link between atrazine and the birth defect because, as they note in their conference abstract, “During the last 10 years, the highest percentage per population of gastroschisis was in Yakima County, in the eastern part of the state, where agriculture is the primary industry.” Overall, Washington state has about double […]

(Beyond Pesticides, February 9, 2010) In an innovative development that could transform the way Americans view the origins of learning and developmental disabilities, the national Learning and Developmental Disabilities Initiative (LDDI) released the first-ever biomonitoring report identifying toxic chemical pollution in people from the learning and developmental disability community. Mind, Disrupted: How Toxic Chemicals May Affect How We Think and Who We Are examines 61 toxic chemicals present in project participants in the context of rising rates of autism, attention-deficit hyperactivity disorder, and other learning and developmental disabilities.   In the U. S., 5-15% of children under age 18 are affected by learning and developmental disabilities. Reported cases of autism spectrum disorders have increased tenfold since the early 1990s. Based on current research, the Centers for Disease Control and Prevention (CDC) states that 1 in 110 eight-year-old children have autism in the United States. Mind, Disrupted measured levels of a set of neurotoxic and endocrine-disrupting chemicals in the participants’ bodies. A growing body of peer-reviewed scientific research, including animal and human studies, shows that these chemicals can disrupt the development and functioning of the brain and nervous system. Eleven of the twelve study participants had detectable levels of triclosan in […]

(Beyond Pesticides, February 8, 2010) The Center for Biological Diversity filed a notice of intent to sue the Environmental Protection Agency (EPA) last week. The lawsuit argues that EPA violated the Endangered Species Act when it approved 394 pesticides known to be harmful to humans and wildlife, without consulting with wildlife regulatory agencies as to the pesticides’ effects on endangered species. By registering pesticides known to harm migratory birds the EPA has also violated the Migratory Bird Treaty Act, according to the suit. The pesticides named in the suit pose a danger not only to wildlife, but to human health as well. Some of the pesticides named include 2,4-D the most commonly used pesticide in the nonagricultural sector, atrazine, triclosan, and pyrethrins. Jeff Miller, conservation advocate at the Center for Biological Diversity, said, “It’s time for the Environmental Protection Agency to finally reform pesticide use to protect both wildlife and people…Many endangered species most affected by toxic pesticides are already struggling to cope with habitat loss and rapid climate changes. For too long this agency’s oversight has been abysmal, allowing the pesticide industry to unleash a virtual plague of toxic chemicals into our environment.” The suit names 887 threatened and […]

(Beyond Pesticides, February 3, 2010) Beyond Pesticides has confirmed exciting additions to Greening the Community, the 28th National Pesticide Forum, scheduled for April 9-10 at Case Western Reserve University in Cleveland, OH. The Forum is an important opportunity to discuss the latest information on pesticides and alternatives, meet scientists and community leaders, and network with other activists working to change policies at the local, state and national levels. David Hackenberg, the beekeeper who first discovered a mysterious disappearance of honeybees now known as colony collapse disorder (CCD), is the most recent addition to the program. Mr. Hackenberg believes that pesticides contribute to CCD and that honeybees are a barometer of the environment. Featured in several films and news investigations, he has been front and center in this important fight to protect our pollinators. Read about Mr. Hackenberg and the other Forum speakers in the highlights below. The Forum will begin Friday afternoon with a tour of the Cleveland Botanical Garden. Founded in 1930, Cleveland Botanical Garden, which is now made up of 20 specialty gardens and exotic indoor biomes, has evolved into a community treasure. The Garden’s community involvement extends beyond its 10 acres into city neighborhoods through its Green […]

(Beyond Pesticides, February 2, 2010) We’re not Cockroaches, EPA. Tell Us What’s in that Toxic Spray! EPA is taking public comments on this important public health and environmental issue and your views are critical to the process. The agency has published a notice proposing the option of full disclosure of all ingredients in pesticide products, including those ithat have been claimed to be trade secrets and withheld from the public. Take a close look at the fine print on a can of Raid, a bottle of Cutters, a jug of RoundUp, or virtually any pesticide on the market today, and you’ll see these words: “Inert ingredients.” Inert ingredients are the pesticide industry’s best-kept secret. The Bad News There are thousands of chemicals used as inerts in pesticides, and over the years we’ve discovered what some of them are. The truth is that many inert ingredients are neither chemically nor toxicologically inert. Some cause cancer, some cause genetic damage, some cause reproductive harm, and others cause a wide variety of other health problems. For decades, EPA has routinely accepted the pesticide industry’s line that these ingredients are “confidential business information.” That’s a red herring. Pesticide companies can easily test their competitors’ […]

(Beyond Pesticides, January 29, 2010) A genetically engineered (GE) variety of brinjal, or eggplant, was approved by India’s Genetic Engineering Approval Committee (GEAC) last October. As the central government decides on approval of the crop’s commercial release, farmers, environmentalists, doctors, and even several state governments have mobilized in protest. India has already approved the commercial cultivation of GE cotton, but this would be the first genetically engineered food crop. Produced by Monsanto, the Bacillus Thuringiensis (Bt) brinjal is engineered to kill insects. Bt is a soil bacteria that produces compounds toxic to certain larval insects. In Bt crops, part of the bacteria’s genome has been incorporated into the plant’s genome, causing the plant to produce these same compounds. An estimated 80% of India’s cotton crop is currently grown from Bt seeds. Concerns about the approval of Bt brinjal has lead to heated protests. While India’s central government is holding a series of public meetings this month to discuss the issue, the first of these meetings ended in a shouting match between protestors and Union Minister of State for Environment and Forests, Jairam Ramesh. The Chief Ministers of several states have also written to Mr. Ramesh urging him not to rush […]

(Beyond Pesticides, January 28, 2010) Scientists convening at the Pan-American Weed Resistance Conference lamented the critical issue that environmentalists have known would eventually happen, and have argued for decades: the resistance of weeds to the broadscale use of the herbicide glyphosate. The conference, hosted by Bayer Crop Science and held in Miami on January 19-21, 2010, was attended by 284 scientists and media representatives from North and South America. One of the scientists in attendance at the recent conference who offered some of the most dire outlooks on the use of glyphosate, according to The Delta Farm Press, was Stephen Powles, a professor of plant biology at the University of Western Australia, and director of the WA Herbicide Resistance Initiative (WAHRI). In some circles, he is known as an authority on herbicide resistance, and says that glyphosate “will be driven to redundancy in the cotton, corn and soybean belt.” Mr. Powles often refers to this area reaching northward into the Corn Belt down through Alabama and Mississippi as the “Glyphosate Belt.” A report that Beyond Pesticides published twelve years ago, “The Environmental Risks of Transgenic Crops: An Agroecological Assessment is the failed pesticide paradigm being genetically engineered?” argued that as […]
