(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, […]

(Beyond Pesticides, March 3, 2008) In a five-year study of the Chesapeake Bay, the nation’s largest estuary, the U.S. Geological Survey (USGS) found that, “Synthetic organic pesticides and their degradation products have been widely detected at low levels in the watershed, including emerging contaminants such as pharmaceuticals and hormones.“ The report finds that concentrations of DDT, while still present, have declined since the 1970s when it was phased out. The findings are contained in a report entitled Synthesis of U.S. Geological Survey Science for the Chesapeake Bay Ecosystem and Implications for Environmental Management. The study is a part of the Chesapeake Bay Program (CBP), which is a multi-agency partnership working to restore the Bay ecosystem. According to the report introduction, “In 2005, which represented the mid-point of the Chesapeake 2000 agreement, there was growing concern at all levels of government and by the public that ecological conditions in the Bay and its watershed had not significantly improved. The slow rate of improvement, coupled with the projected human-population increase in the Bay watershed, implied that many desired ecological conditions will not be achieved by 2010. The Government Accountability Office (2005) recommended that the CBP complete efforts for an integrated assessment approach […]

(Beyond Pesticides, February 29, 2008) The National Park Service (NPS) recently released a report documenting airborne pesticides.  The report of the  Western Airborne Contaminants Assessment Project (WACAP), with data collected from 2002 to 2007, found high concentrations of “numerous” airborne contaminants, including current and former use pesticides. Contamination is widespread throughout twenty parks throughout the western United States and Alaska, exceeding consumption levels for humans and wildlife in some areas. According to the report, the contaminants of second and third “highest concern” are “Dieldrin – an acutely toxic insecticide banned from use in the U.S. since 1987 that decreases the effectiveness of the immune system” and “DDT – an insecticide banned in the U.S. since 1972 that reduces reproductive success.” NPS also reported that Dieldrin and DDT levels exceeded the threshold for recreational fishermen in several parks, and Dieldrin levels exceeded that for subsistence fishermen in all but Olympic National Park. Fish-eating birds are also at risk in some parks. While NPS could not establish a correlation between contaminant levels and fish reproductive effects due to small sample size, two parks produced individual “intersex” fish. However, NPS stated, “This condition is commonly associated with exposure to certain contaminants (e.g., dieldrin […]

(Beyond Pesticides, February 19, 2008) Common household chemicals and widespread pollutants are changing male reproductive health and impacting sexual function, development and cancer rates of today’s generations and possibly their offspring, according to more than 15 years of research by a Colorado State University expert. For example, one study looking at sperm counts globally from 1940, when chemicals first began to be widely produced, to the 1990s, indicates a 1.15 percent per year decline in sperm counts. These declines may be linked to chemical exposure.Rao Veeramachaneni, BVSc, MScVet, PhD, a biomedical sciences professor in the College of Veterinary Medicine and Biomedical Sciences, has found that chemicals including pesticides, common pollutants in ground water, and chemicals in plastics, make-up and nail polish are on a growing list of culprits causing developmental abnormalities such as impaired sperm quality and impotence. Reproductive health can be compromised if males are exposed at various times in life spanning from in utero up to adulthood.Dr. Veeramachaneni’s findings span the globe and are across species lines, from humans to horses, wildlife to frogs. His research, coupled with the collective findings of other experts in the field, indicates a strong link related to pollutants, and incidence of such […]

(Beyond Pesticides, January 29, 2008) University of Cambridge scientists say there may be a link between persistent organic pollutants (POPs), including pesticides, and Type 2 Diabetes. The Cambridge scientists are advocating additional research into the little understood links between environmental pollution and adult onset diabetes. In the most recent edition of the journal Lancet, Oliver Jones, Ph.D., and Julian Griffin, Ph.D., highlight the need to research the possible link between persistent organic pollutants (POPs, a group which includes many pesticides) and insulin resistance, which can lead to adult onset diabetes. In their commentary, Dr. Jones and Dr. Griffin cite peer reviewed research including that of D. Lee, et al, which demonstrated a very strong relationship between the levels of POPs in blood, particularly organochlorine compounds, and the risk of type 2 diabetes. “Of course correlation does not automatically imply causation,” says Dr. Jones. “But if there is indeed a link, the health implications could be tremendous. At present there is very limited information. Research into adult onset diabetes currently focuses on genetics and obesity; there has been almost no consideration for the possible influence of environmental factors such as pollution.” Interestingly, in the Lee study an association between obesity and […]

(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 […]

(Beyond Pesticides, December 17, 2007) People exposed to banned organochlorine pesticides and other toxic chemicals that persist in the environment are more likely to develop non-Hodgkin lymphoma (NHL), according to new research funded by the British Columbia Cancer Agency. The study, “Organochlorines and risk of non-Hodgkin lymphoma”, was published in the International Journal of Cancer on December 15, 2007 and is so far the largest to examine organochlorines in plasma and their link to illness. The researchers measured the levels of pesticides or pesticide metabolites and congeners of polychlorinated biphenyls (PCBs) in the blood of 880 British Columbians, half with NHL and the other half control subjects. Several pesticide analytes and a number of congeners showed a significant association with NHL. Non-Hodgkin lymphoma is the fifth most common cancer in Canada and the most common type of lymphoma. “We know that the incidence of non-Hodgkin lymphoma has been steadily rising for the past 30 years worldwide, but there hasn’t been clear evidence to explain the increase,” says Dr. John Spinelli, Ph.D., lead author and a senior scientist at the BC Cancer Agency. “Our study helps to provide answers to this puzzle by showing a strong link between these specific environmental […]

(Beyond Pesticides, November 26, 2007) Minnesota’s Department of Health (MDH) plans to measure arsenic levels in 100 children who live near a former pesticide production site in south Minneapolis. Pesticides containing arsenic, a known human carcinogen, were made and stored at the CMC Heartland site between 1938 and 1963. The pilot project follows the passage of health tracking and biomonitoring legislation and would help to determine whether children in south Minneapolis have elevated levels of arsenic in their bodies. Children who are found to have elevated levels would be advised to seek medical attention. Also, health officials would give families information to help them determine how they might be exposed to arsenic (including the soil, green-treated lumber, foods, dietary supplements and cigarette smoke) and to take steps to reduce the exposure in the future. Health Department staff members aim to begin the project in the summer of 2008 and will present preliminary plans and accept feedback on the proposal at a public meeting at December 6 at 7 p.m. at the Midtown YWCA, 2121 E. Lake St. Health officials have said that the risk from the contaminated soil is low, particularly since much of the contaminated soil is under grass […]

(Beyond Pesticides, October 18, 2007) In a scholarly review written by Theo Colborn, Ph.D. and Lynn Carroll, Ph.D., the authors point to the multigenerational effects of some pesticides that they say demand improved regulation to protect human and environmental health. The review, “Pesticides, Sexual Development, Reproduction, and Fertility: Current Perspective and Future Direction,” appears in the international journal Human and Ecological Risk Assessment (13:5, 1078 — 1110), September, 2007. The study points out a major deficiency in the U.S. Environmental Protection Agency’s regulation of pesticides under current health reviews and risk assessments. The authors call EPA’s pesticide registration system “outmoded” and one that has “almost completely missed the low-dose and endocrine system-mediated effects of pesticides.” The study reviews both epidemiological and laboratory data. In the abstract, the authors state the following: Improvements in chemical analytical technology and non-invasive sampling protocols have made it easier to detect pesticides and their metabolites at very low concentrations in human tissues. Monitoring has revealed that pesticides penetrate both maternal and paternal reproductive tissues and organs, thus providing a pathway for initiating harm to their offspring starting before fertilization throughout gestation and lactation. This article explores the literature that addresses the parental pathway of exposure […]

(Beyond Pesticides, September 24, 2007) Seven representatives wrote to the EPA last Thursday, urging the government agency to act promptly to identify and screen products for dangerous endocrine-disrupting chemicals. The letter asks EPA Administrator Stephen Johnson to provide definite deadlines in the testing and control of endocrine disruptors, which are substances that interfere with the normal functioning of the endocrine system, responsible for hormonal and developmental processes. EPA’s regulation of these substances that mimic or alter natural hormonal processes has been slow and lacks direction to meet set goals promptly, according to the U.S. Representatives. “To date, EPA’s efforts in this area have been characterized by missed deadlines, prolonged delays, and inadequate incorporation of public input,” according to the letter from the House Committee on Oversight and Government Reform, chaired by Rep. Henry Waxman (D-California). Ranking Minority Member on the Committee Tom Davis (R-Virginia); Representatives Elijah Cummings (D-Maryland), Chris Van Hollen (D-Maryland), Wayne Gilchrest (R-Maryland), and Jim Moran (D-Virginia); and Delegate Eleanor Holmes Norton (D-D.C.) also signed the letter to EPA. Advocates say that EPA’s lack of urgency on endocrine disruptors leaves the American population and future generations at risk for adverse health effects from exposure to these substances through […]

(Beyond Pesticides, September 18, 2007) On September 16, 2007, researchers from the National Institute of Environmental Health Sciences presented findings to the European Respiratory Society Annual Congress in Stockholm showing that exposure to several commonly used pesticides increases the risk of asthma in farmers. Pesticide exposure is a “potential risk factor for asthma and respiratory symptoms among farmers,” lead author Dr. Jane A. Hoppin told Reuters Health. “Because grains and animals are more common exposures in agricultural settings, pesticides may be overlooked. Better education and training of farmers and pesticide handlers may help to reduce asthma risk.”The study consisted of 19,704 farmers, 441 of which had asthma. Farmers who have experienced high pesticide exposure were twice as likely to have asthma. Sixteen of the pesticides studied were associated with asthma. Coumaphos, EPTC, lindane, parathion, heptachlor, 2,4,5-TP, DDT, malathion, and phorate had the strongest effect. “This is the first study with sufficient power to evaluate individual pesticides and adult asthma among individuals who routinely apply pesticides,” Dr. Hoppin said. Asthma is a serious chronic disorder of the lungs characterized by recurrent attacks of bronchial constriction, which cause breathlessness, wheezing, and coughing. Asthma is a dangerous, and in some cases life-threatening disease. […]

(Beyond Pesticides, September 4, 2007) Scientists identified an important biochemical piece in the passage of malaria from mosquitoes to humans. If this link in the chain can be broken at its source””the mosquito””then the spread of malaria could be stopped without the use of harmful pesticides or costly drugs. “Mosquito Heparan Sulfate and Its Potential Role in Malaria Infection and Transmission,” published in the August 31 issue of the Journal of Biological Chemistry, contains the findings of the interdisciplinary team led by researchers from Rensselaer Polytechnic Institute. The research group found that humans and the mosquitoes that carry the malaria parasite Plasmodium share the same complex carbohydrate, heparan sulfate. In both humans and mosquitoes, heparan sulfate is a receptor for the Plasmodium, binding to the parasite and giving it quick and easy transport through the body. Robert J. Linhardt, Ph.D., professor of Biocatalysis and Metabolic Engineering at Rensselaer, led the team. “The discovery allows us to think differently about preventing the disease. If we can stop heparan sulfate from binding to the parasite in mosquitoes, we will not just be treating the disease, we will be stopping its spread completely,” Dr. Linhardt said. Malaria parasites are specific to their host, […]

(Beyond Pesticides, August 20, 2007) Environmental groups launched a public campaign last Wednesday to urge state officials to stop applying toxic herbicides for vegetation control along state roadways. Members of the Massachusetts Coalition for Pesticide Reduction maintain that herbicides, which the state resumed using in 2003, are harmful to people and the environment. Sylvia Broude, community organizer for Toxics Action Center, said toxic chemicals such as the ones the Highway Department uses can harm more than just the intended target. The chemicals can run off highways, pollute drinking water and eventually lead to health problems in humans, ranging from eye problems and learning disabilities to some forms of cancer, she said. The group is asking the state to use organic herbicides or manual means, such as weed whackers or lawnmowers, which the state used exclusively in the early 2000s. But state officials say affected areas are in small, controlled environments. The Highway Department says that it removes unwanted bushes and weeds manually or mechanically on the vast majority of the 48,200 acres it maintains but needs the herbicides for about 188 acres, less than half of 1 percent of the total. Spokesman John Lamontagne said removing weeds mechanically in some […]

(Beyond Pesticides, August 17, 2007) The widespread presence of pesticides and other agricultural runoff has been confirmed in the world’s largest coral reef system. Degradation of the system threatens not only a natural treasure but also the region’s economy. Australia’s Great Barrier Reef is the subject of a recent report by the Great Barrier Reef Marine Park Authority. Entitled the “Annual Marine Monitoring Report 2006,” the study confirms extensive contamination in eight of the ten major tributaries into the marine park, much of which is fertilizer and pesticide runoff from the area’s farmland. Local environmental groups are calling for government protection of the reef from these pollutants, and tourism interests worry that damage to the reef will reduce the number of visitors to Australia. According to World Wildlife Foundation-Australia program leader Nick Heath, “Reducing pollution load is possible and will help us save the Reef, as well as the 60,000 tourism jobs based around the Reef.” According to the report, “Water quality in the Great Barrier Reef is principally affected by land-based activities in its adjacent catchments, including vegetation modification, grazing, agriculture, urban development, industrial development and aquaculture. Nutrients, sediments and pesticides are the pollutants of most concern for the […]

(Beyond Pesticides, August 9, 2007) China reports it is cracking down on the use of recently banned pesticides and is taking additional actions in an effort to counter concerns about the country’s food safety. The major exporter has been the subject of frequent reports of contaminated products, including several foods imported by the U.S. Reuters reports that according to a new poll, U.S. consumers are extremely wary of products made in China, and nearly two-thirds said they would support a boycott of Chinese goods. In reaction to the potential loss of export markets and the upcoming Beijing Olympics, China says it will spend more than $1 billion improving food and drug safety over the next three years. The Chinese government will specifically launch a campaign to crack down on the use of banned pesticides that are still being manufactured and remain in use. The campaign is in response to news reports that “a dozen or so” pesticide producers were still making highly poisonous pesticides such as methylamine and phosphamidon. Prior to the recent ban, 1,500 pesticide manufacturers, approximately half of the industry, produced the chemicals. However, pesticides that are still approved for use in China are also raising concerns as […]

(Beyond Pesticides, August 7, 2007) In a study that examines the influence of age of exposure on the magnitude of the association between DDT and breast cancer risk finds that women who were exposed to DDT before the age of 14 are five times more likely to develop breast cancer later in life. In contrast, the study finds exposure after adolescence does not increase risk. The data used in the study targets the age of a woman in 1945 as an indicator for the youngest possible age for a woman to be exposed to DDT, since DDT was first introduced to the U.S. for mosquito control in 1945. The researchers, from the Center for Research on Women’s and Children’s Health, Public Health Institute at Berkeley, California and the Mount Sinai School of Medicine, analyzed blood that had been collected from women between 1959 and 1967 – years during which the use of DDT was at its highest. “DDT and breast cancer in young women: New data on the significance of age at exposure,” published last week in the online edition of the journal Environmental Health Perspectives, is “the first study specifically designed, a priori, to consider whether age at exposure […]

(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 […]

(Beyond Pesticides, June 29, 2007) On June 28, 2007, forty years after it received protection under the Endangered Species Act (ESA) and thirty-five years after the banning of DDT in the U.S., the bald eagle was removed from the ESA’s “threatened” list. Bald eagle populations declined dramatically in the last century, attributed mostly to the accumulation of the pesticide DDT in fish, a staple of the eagle’s diet. The pesticide gradually poisoned females, causing them to produce thinly-shelled eggs that broke easily, preventing the embryos from growing. Years of hunting, accidental poisoning and habitat loss took an additional toll. “The rescue of the bald eagle from the brink of extinction ranks among the greatest victories of American conservation.” said John Flicker, President of the National Audubon Society. “Like no other species, the bald eagle showed us all that environmental stewardship has priceless rewards. In every state, parents and grandparents can still point to the sky and share a moment of wonder as a bald eagle soars overhead.” The U.S. Fish and Wildlife Service (FWS) in 1967 listed the bald eagle as endangered, a designation that gave the bird legal protection from harmful human activities and in 1972, the U.S. Environmental […]

(Beyond Pesticides, June 8, 2007) New research shows that pesticides can reduce the efficiency of nitrogen-fixing plants, impacting soil fertility and ultimately reducing crop yields. The insecticides methyl parathion, DDT and pentachlorophenol were among the chemicals found to inhibit or delay the symbiotic relationship between the legume alfalfa and rhizobia bacteria, which is crucial to nitrogen fixation. Legume crops are often cultivated to help replenish the vital soil nutrient nitrogen (N), but legumes cannot achieve this on their own — Rhizobium bacteria interacts with legumes to convert atmospheric N to nutrient compounds utilizable by plants. Legumes like alfalfa and soybeans are often included in crop rotations due to this beneficial relationship. Nitrogen fixation resulting from the symbiotic relationship between leguminous plants and species of Rhizobium bacteria is an ecological service estimated to be equivalent to $10 billion worth of synthetic N fertilizer annually. Symbiotic nitrogen fixation (SNF) reduces the need for synthetic fertilizers, which cause environmental problems such as impaired water quality. Acknowledging that SNF is both initiated and maintained by chemical signals between the host plant and the beneficial bacteria, the research team postulated that natural and synthetic chemicals could disrupt these signals. The study shows “previously undescribed in […]

(Beyond Pesticides, May 25, 2007) Rachel Carson, a timely and key voice responsible for warning the public about the dangers of chemical pesticides, would be turning 100 this weekend. Despite succumbing to breast cancer in 1964, her legacy lives on – Rachel Carson’s fight continues today, as her work is more relevant than ever. Rachel Carson authored the seminal book of the modern environmental movement, Silent Spring, published in 1962. The book detailed detrimental effects of pesticides on the environment, focusing on bird decline and DDT use. Her message had and continues to have a profound effect, calling on people to think beyond wilderness conservation efforts when protecting the environment – to think about what is happening in every ecosystem, including our own backyards. Silent Spring was instrumental in setting off a chain of events, including Earth Day and the formation of the U.S. Environmental Protection Agency, which subsequently banned almost all DDT use in 1972. Despite all of the honors, awards and praise that have been given in the memory of Rachel Carson, her cause continues to be controversial, especially regarding the dangers of DDT. The latest row has surfaced over claims that the decline in DDT use internationally […]
