(Beyond Pesticides, April 6, 2010) A new report analyzing regulations from California’s 25 top agricultural counties finds that many counties do more to protect crops than children from potentially harmful pesticide drift. The report, Pesticide Protection Zones: Keeping Kids Safe at School, finds that eleven counties have no protection zones around schools at all, while another six only limit spraying when school is in session. By contrast, the report notes that nearly 25% of the counties have larger pesticide buffer zones for crops than for schools. “It seems insane to have stringent rules protecting nuts and peaches while schoolchildren remain at risk from chemicals that can cause cancer, birth defects, and other serious health problems,” said Paul Towers, director of Pesticide Watch Education Fund and a co-author of the report. “But that’s exactly what’s happening in counties across California. It is past time for a simple, statewide rule that protects all California children from pesticide drift at school.” “Our children deserve to be protected from these cancer-causing chemicals,” said Assembly member Sandré Swanson, who has introduced AB 1721, the Health and Safety School Zones Act, to fix the problem. “The people of California have made it clear that clean air […]

(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, January 26, 2010) Pesticide use declined in California for a third consecutive year in 2008, according to the state’s Department of Pesticide Regulation (DPR). Approximately 162 million pounds of reported pesticides were applied statewide, a decrease of nearly 10 million pounds – or 6 percent – from 2007. Pesticide use in production agriculture fell by 9.6 million pounds and in most other categories as well, including structural pest control and landscape maintenance. Reports are mandatory for agricultural and pest control business applications, while most home, industrial and institutional uses are exempt. DPR Director Mary-Ann Warmerdam emphasized that pesticide use varies from year to year depending on a number of factors, including weather, pest problems, economics and types of crops planted. Increases and decreases in pesticide use from one year to the next or in the span of a few years do not necessarily indicate a general trend. “California experienced another dry winter and spring in 2008, which helps explain why fungicides showed the greatest decrease in use by both pounds and acres treated,” Ms. Warmerdam said. “Herbicide use also fell by pounds and acres treated, indicating fewer weeds.” Sulfur was again the most highly used pesticide in 2008 […]

(Beyond Pesticides, October 28, 2009) Transcripts released last week from an external peer review panel convened in September to evaluate California’s Department of Pesticide Regulation’s (DPR) risk assessment of the fumigant methyl iodide show that the panel’s leading scientists have serious concerns about this chemical. Methyl iodide is currently being considered for use on California’s crops, especially strawberries. The scientific panel held a public workshop, entitled “Methyl Iodide External Peer Review Panel Workshop,” on September 24-25, 2009 in Sacramento, CA as part of an additional, external peer review for methyl iodide. Previously planned public and scientific review processes were subject to cancellation or postponement by the Governor’s office. Led by John Froines, Ph.D., director of the Center for Occupational and Environmental Health at the University of California, Los Angles, the panel consisted of eight experts in various scientific fields. The scientists expressed concern over inadequate buffer zones, ground water contamination and drinking water exposures, body burden, neuro-degeneration, reproductive toxicity and carcinogenicity that are associated with methyl iodide use and exposures. Panel members also challenged EPA’s assessment and found EPA’s scientific conclusions on methyl iodide to be lacking. The transcripts and other workshop presentations are available here. These concerns underscore previous […]

(Beyond Pesticides, September 30, 2009) The Center the Food Safety and the Resource Institute for Low Entropy Systems have petitioned the City of San Francisco and the San Francisco Public Utilities Commission (SFPUC) to immediately suspend the SFPUC’s Compost Giveaway program because the compost is made with sewage sludge which contains toxic chemicals and hazardous materials. The petition, submitted last Wednesday, cites that the distribution of contaminated compost will spread toxic sludge to homeowners’ backyards, increasing the risk of health problems to children and the community. The SFPUC’s compost giveaway program distributes free compost as part of the commission’s recycling efforts to community gardens, school gardens and local residents. The compost is made of sewage sludge, derived as a by-product of wastewater and sewage treatment, and contains heavy metals, pathogens, pharmaceuticals, PCB’s, flame retardants and endocrine disruptors, such as the antibacterial triclosan. “San Franciscans may think they’re getting a gift from the city, but this is no gift. City residents could be at serious risk of poisoning from the application of sewage sludge to local crops and gardens,” said Paige Tomaselli, staff attorney for the Center for Food Safety. “With this petition, we’re strongly urging the Mayor to put an […]

(Beyond Pesticides, September 17, 2009) Last week, the Centers for Disease Control and Prevention (CDC) awarded $5 million to the states of California, New York and Washington to conduct biomonitoring surveys to assess public exposure to chemicals and toxic substances. This will allow the states to determine which environmental chemicals people have been exposed to and how much of those chemicals are in their bodies. Many U.S. residents carry toxic pesticides in their bodies above government assessed “acceptable” levels. Biomonitoring, which measures levels of chemicals directly in people’s blood or urine, has become increasingly helpful for assessing people’s exposure to toxic substances as well as for responding to serious environmental public health problems. The PANNA report “Chemical Trespass: Pesticides in Our Bodies and Corporate Accountability” in 2004, which compiled data from previous CDC biomonitoring surveys found that children, women and Mexican Americans carried the heaviest “pesticide body burden.” Another biomonitoring study by the World Wildlife Fund UK in 2003, revealed that chemicals, such as DDT, which have been banned for decades and are associated with cancer, immune system disorders, and other health problems, are still found in people today. “Biomonitoring measurements are considered the most health-relevant assessments of exposure because […]

(Beyond Pesticides, August 7, 2009) A recent study published in the journal Environmental Health Perspectives has added to evidence that certain pesticides significantly increase one’s risk of developing Parkinson’s disease (PD). Researchers found that rural residents who drank private well water within 500 meters of fields sprayed with certain pesticides had an increased – up to 90 percent – risk of developing PD, and those with Parkinson’s “were more likely to have consumed private well water, and had consumed it on average 4.3 years longer.” The study evaluated more than 700 people, including carefully chosen controls, in Fresno, Kent, and Tulare counties. 17 percent reported drinking private well water between 1974 and 1999. Researchers focused on wells’ proximity to agricultural fields sprayed with pesticides, since private wells are not regulated, and many are shallow enough to be contaminated by pesticides seeping into groundwater. Researchers looked at 26 pesticides and six in particular, “selected for their potential to pollute groundwater or because they are of interest for PD, and to which at least 10% of our population were exposed.” Those are: diazinon, chlorpyrifos, propargite, paraquat, dimethoate, and methomyl. Propargite exposure was most closely correlated with incidence of PD, with a 90 […]

(Beyond Pesticides, August 5, 2009) In a letter authored by Senator Mark Leno and Assemblymember Bill Monning, and signed by twenty-five state legislators, the signatories called on Governor Schwarzenegger to keep the controversial pesticide methyl iodide out of California’s strawberry fields. “We strongly believe that methyl iodide has no role to play in building a secure, viable and healthy agricultural economy in the 21st Century,” said authors Senator Leno and Assemblymember Monning. On August 19, the Assembly Labor and Employment Committee will meet to explore the approval of methyl iodide and the potential impact on workers. “While I am encouraged at the decision of DPR to pursue the external peer review and public testimony, I still believe it is imperative to devote a special informational hearing by the Assembly Labor and Employment Committee focused on worker health and safety issues related to the potential registration of Methyl Iodide,” said Assemblymember Monning. “We are pleased that this group of legislators is taking the lead to protect public health. The scientific review of methyl iodide is very important in this case because of the sheer number of hazards it poses–cancer, thyroid disease, miscarriages, and neurotoxicity. This highly politicized process needs a reality […]

(Beyond Pesticides, July 13, 2009) With the stroke of a pen, Governor Arnold Schwarzenegger could bow to industry interests and force the California Department of Pesticide Regulation to register a new fumigant pesticide, methyl iodide. Highly toxic, and not approved for use in California, this chemical has been given a comprehensive review by the state’s own Department of Pesticide Regulation (DPR) and found to be one of the riskiest pesticides in existence. Scientists familiar with methyl iodide are asking Mr. Schwarzenegger to let science, rather than political pressure, guide this decision. “Methyl iodide is so toxic that scientists working with it in the laboratory take extreme precautions when handling it, using a ventilation hood, gloves, and special equipment for transferring it so it does not escape to the air,” notes Susan Kegley, Ph.D., a chemist and consulting scientist for Pesticide Action Network North America. “This degree of protection is not possible in an agricultural setting where the pesticide would be applied at rates of 175 pounds per acre in the open air. Buffer zones of 400 feet (a distance most growers would say is unworkable) for a 40-acre fumigation would still result in a dose of methyl iodide to neighbors […]

(Beyond Pesticides, July 6, 2009) Last week, the U.S. Environmental Protection Agency (EPA) proposed to formally evaluate the harmful effects of 74 pesticides on 11 endangered and threatened species in the San Francisco Bay Area over the next five years, and to impose interim restrictions on use of these pesticides in and adjacent to endangered species habitats. The proposal stems from a settlement agreement with the Center for Biological Diversity, which sued EPA in 2007 for violating the Endangered Species Act by registering and allowing the use of toxic pesticides in Bay Area endangered species habitats without determining whether the chemicals jeopardize those species’ existence. “Tens of millions of pounds of toxic and poisonous chemicals, known to be deadly to endangered species and harmful to human health, including proven carcinogens and endocrine disruptors, are applied in the Bay Area each year, and many of those find their way through runoff or drift into our soil, creeks and rivers, San Francisco Bay, and sensitive wildlife habitats,” said Jeff Miller, conservation advocate with the Center. “The toxic stew of pesticides in the Bay-Delta has played a major role in the collapse of native fish populations, and pesticides are a leading cause of […]

(Beyond Pesticides, July 2, 2009) The EPA has just finished up with a round of public hearings on a proposed plan to cap a part of the Palos Verdes Superfund Site. This 17 square mile area of ocean floor off the Southern coast of California is home to one of the largest deposits of DDT in the U.S. Despite the fact that this chemical has been banned in the U.S. for almost four decades, there is an approximate 110 tons of DDT in the sediment of the Palos Verdes Shelf. Concentrations of DDT and PCBs in fish continue to pose a threat to human health and the natural environment including the discovery of highly contaminated fish. In addition, a surge of additional problems with the lingering effects of DDT have risen in recent years, particularly with its buildup in our waterways. It has currently been identified as a threat to the Columbia River, as well as to the arctic. It has also been linked to a plethora of health concerns, including breast cancer, diabetes, non Hodgkin lymphoma, and autism. Most of the contamination of the Palos Verdes Shelf is attributed to The Montrose Chemical Corporation of California. At one time […]

(Beyond Pesticides, June 12, 2009) An independent review is challenging government noncomplicance with a 1998 Marin County, California law that prohibits the use of certain highly toxic pesticides by any department. The research by an independent citizen has uncovered dozens of violations of the county’s own law until as recently as 2007. Local groups have called for an investigation by the Board of Supervisors, as well as more protective wording put into a revision of the county’s pesticide policy. The county law states that no department may use “any ingredient classified by the U.S. Environmental Protection Agency as a human carcinogen, probable human carcinogen, possible human carcinogen, reproductive toxin, or developmental toxin.” According to a report by Corte Madera resident Paul Apfel, county employees violated that law at least 92 times between 1999 and 2007, using thousands of gallons of chemicals. “We have verified that the county has used a class of chemicals that the IPM [Integrated Pest Management] ordinance identifies should only be used under the exemption process,” said County Administrator Matthew Hymel. “Part of the confusion is that these chemicals were not on the state list but they were on the EPA list of possible carcinogens.” Fred Crowder, […]

(Beyond Pesticides, June 1, 2009) Many believe that nature’s best weed control is goats and that is why the Maryland Department of Transportation, town of Heampstead, New York, Google Corporate office campus in Mountain View, California, Mesa, Arizona Utilities Department and City of Cheyenne, Wyoming are putting goats to work this spring. Whether its 5 or 700 goats managing weeds, brush and grasses along highways, on a nature preserve, on a corporate campus or on a water reclamation plant property, goats are doing the work in an environmentally-friendly way. Goats eat unwanted plants, add fertilizer to the area and aerate the soil with their hooves, all at the same time. They show up every day to work, never complain, and they are tireless in performing their job. Maryland Department of Transportation The Maryland Department of Transportation’s State Highway Administration (SHA) had a major dilemma — how to mow the turf amid the meadows and bogs that protect the threatened Bog Turtle around a major highway bypass in the state. The best solution — use goats as lawn mowers. In late May, SHA enlisted a herd of 40 goats from a local farmer to begin a conservation grazing project on approximately […]

(Beyond Pesticides, May 1, 2009) The California State Senate’s Health Committee last week passed legislation that provides public health agencies and emergency responders timely access to complete ingredient lists of aerial pesticides. Senate Bill 759, authored by Senator Mark Leno (D-San Francisco), requires the disclosure of inert or inactive ingredients in pesticides before they are approved for use by state regulators. The bill passed committee with a 8-2 bipartisan vote. “In case of an emergency, it is critical that our health care professionals can easily access a complete list of pesticide ingredients so they can properly treat anyone who was exposed to them,” said Senator Leno. “Current law keeps emergency responders in the dark by permitting pesticide manufacturers to shield many of the ingredients they use from public disclosure,” he said. Federal regulation requires pesticide manufacturers to disclose the ingredients of industrial chemicals only if they are classified as “active” ingredients. More than 99 percent of the ingredients in certain pesticides are designated as inert or inactive, so they are never disclosed to the public. According to the U.S. Environmental Protection Agency (EPA), many consumers have a misleading impression of the term “inert ingredient,” believing it to be water or […]

(Beyond Pesticides, April 30, 2009) On April 20, the National Marine Fisheries Service (NMFS) released a Biological Opinion (BiOp) finding that three additional pesticides, carbaryl, carbofuran, and methomyl, harm salmon and steelhead protected under the Endangered Species Act (ESA). The BiOp prescribes measures necessary to keep these pesticides out of salmon waters in Washington, Oregon, California, and Idaho. It is the second such plan issued in the last six months under a court settlement with fishermen and conservationists, filed by the non-profit law firm Earthjustice. The previous BiOp identified three organophosphate insecticides: chlorpyrifos, diazinon, and malathion. “These pesticides are designed to kill insects on agricultural crops, but when they get into the water system, they also kill aquatic insects that salmon feed on.” said Angela Somma, who heads the NMFS endangered species division. Under the terms of settlement, the Environmental Protection Agency (EPA) must implement measures within a year-long timeframe to prevent further exposure of the pesticides to the water that cultivate these species. The measures recommended by NMFS include: a ban on application of the three pesticides in windy conditions and buffer zones near water resources and require that land applications must be at least 50-600 feet from the […]

(Beyond Pesticides, April 28, 2009) On April 23, 2009, the Natural Resources Defense Council (NRDC) filed a lawsuit, NRDC v. Albertsons, Inc. et al, in California against major pet product retailers and manufacturers for illegally selling pet products containing a known cancer-causing chemical called propoxur without proper warning labels. In new scientific analysis also released the same day, NRDC found high levels of propoxur and tetrachlorvinphos (TCVP), another carcinogenic neurotoxin common in household pet products, on pet fur after use of ordinary flea collars. NRDC is also petitioning the Environmental Protection Agency (EPA), calling for the removal of these chemicals from pet products. “Just because a product is sold in stores does not mean it is safe,” said Gina Solomon, MD, NRDC senior scientist and physician. “Under California law, consumers have a right to know if a flea control product exposes them to health risks before they buy it.” NRDC filed its lawsuit in California Superior Court in Alameda County against 16 retailers and manufacturers including Petsmart, PetCo, and Petstore.com, for failing to comply with California’s Safe Drinking Water and Toxic Enforcement Act, known as Proposition 65, which prohibits businesses from knowingly exposing consumers without proper warning to any chemical […]

(Beyond Pesticides, April 24, 2009) The California Department of Pesticide Regulation this week finalized looser pesticide rules that will allow more emissions from soil fumigant pesticides. Environmental activists are alarmed that this new ruling will only serve to slow efforts to clean the smoggy air in California’s Central Valley. This regulatory action revises the total pesticide emission benchmarks in the Sacramento Metro, San Joaquin Valley, South Coast, Southeast Desert, and Ventura areas. The ruling is a victory for chemical-intensive farmers, who fear that stricter limits would force some growers to stop using pesticides. Pesticides, especially soil fumigants, which are injected into soil to kill pests by releasing toxic gases, contribute to about 6% of the smog problem in the Valley, according to state figures. According to the state’s Department of Pesticides Regulation, the looser limit will still “meet our obligation to reduce pesticide emissions, but do so in a way that avoids placing an unreasonable or disproportionate burden on fumigant pesticide users.” For the San Joaquin Valley for example, the rule sets the emissions limit at 18.1 tons per day, 2.1 tons higher than what activists wanted. The regulations cover the prime growing season of May 1 though October 31 […]

(Beyond Pesticides, April 22, 2009) The California Department of Pesticide Regulation (DPR) released its “Top Pesticide Blunders” report to remind the public to avoid illness and injury by using household cleaning and gardening products that pose the least risk to their health and the environment. The blunders also include situations in which users of toxic products fail to comply with product labels. “Disinfectants, mold and mildew cleaners, weed killers and pool chemicals are just a few of the many over-the-counter pesticide products available for home use,” DPR Director Mary-Ann Warmerdam said. “As people begin their spring cleaning and gardening, they should select products that best target the problem and then follow the label instructions carefully to prevent accidents.” Beyond Pesticides adds that people should consider non-chemical approaches that manage unwanted insects and plants with prevention-oriented practices. Ms. Warmerdam suggests the following precautions to prevent pesticide exposure in and around the home: *Select products that pose the least risk to your health and the environment — do you really need a pesticide for the task? *Never put pesticides in food or drink containers. Keep pesticides in their original containers so they are not mistaken for food or drink. *Store pesticides properly […]

(Beyond Pesticides, April 6, 2009) Despite an earlier report showing a decrease in pesticide use in the state, pesticide-related illnesses and injuries in California have doubled in 2007 from 2006, according to new data from the California Department of Pesticide Regulation (DPR). The 2007 pesticide exposure data also shows that twice as many illnesses investigated are associated with non-agricultural pesticide use than are reported for agricultural purposes. A total of 45 percent of the illnesses investigated are associated with pesticide exposure to structural, sanitation and home garden pesticide use, while 22 percent are associated with agricultural pesticide use. The 2007 illness and incident data show that 1,479 illnesses were investigated and 66 percent, or 982 cases, were linked to pesticide exposure. For 157 cases, information was unavailable for investigation follow-up, yet, should not necessarily be discounted. The major findings of the data show that:  The majority of pesticide illnesses are associated with chlorpyrifos, malathion, chlorine, and cypermethrin;  The largest number of pesticide illnesses were from pesticide drift;  For occupational cases, the most common activity during pesticide exposure were for applicators and fieldworkers;  For non-occupational cases, the most common activity during exposure were being in an indoor […]

(Beyond Pesticides, March 16, 2009) Exposure to a mixture of the fungicide maneb and the herbicide paraquat significantly increases the risk of developing Parkinson’s disease, according to a new University of California, Berkeley study, “Parkinson’s Disease and Residential Exposure to Maneb and Paraquat from Agricultural Applications in the Central Valley of California.” Published in the American Journal of Epidemiology, the study findings show that exposure to both pesticides within 500 meters of an individual’s home increases the risk of developing Parkinson’s by 75 percent. For individuals 60 years of age or younger at the time of diagnosis, there is a more than four-fold increase in risk of the disease when exposed to a combination of maneb and paraquat and a more than doubling of risk when exposed to either maneb or paraquat alone. The Berkeley researchers used geographic information systems that analyzed data from California Pesticide Use Reports and land-use maps to calculate historical residential exposure to agricultural exposure to the two pesticides. From 1998 to 2007, the researchers enrolled 368 incident Parkinson’s disease cases and 341 population controls from California’s Central Valley and developed potential exposure estimates incurred between 1974 and 1999. Also published this month by some of […]

(Beyond Pesticides, February 26, 2009) On February 24, the U.S. Environmental Protection Agency settled with an Oakland, California, importer for $61,000 for allegedly selling and distributing illegal mothballs, a violation of federal pesticide laws. The importer is accused of distributing unregistered naphthalene mothballs from imported from Taiwan. Venquest Trading, imported unregistered naphthalene mothballs from Taiwan and distributed them to retailers in California and the Pacific Northwest on 241 separate occasions. EPA’s Pacific Northwest region first discovered the company’s violations during a marketplace initiative to uncover illegal pesticide products. The agency’s Pacific Southwest office later conducted an inspection and uncovered violations at Venquest’s Oakland warehouse. “Without proper labeling and registration, these illegal pesticides pose a serious threat to human health, particularly children’s health, who can mistake the mothballs for candy,” said Katherine Taylor, associate director of the EPA’s Communities and Ecosystems Division for the Pacific Southwest region. “Importing unregistered pesticides is a serious violation, as the registration process ensures we know what the pesticide contains, and that it is properly labeled with precautionary statements and directions for use.” EPA has fined more than a dozen companies over the last several years for selling illegally imported mothballs. Importers, dealers and retailers can […]

(Beyond Pesticides, January 23, 2009) A study by researchers at the UC Davis M.I.N.D. Institute has found that the seven- to eight-fold increase in the number children born in California with autism since 1990, a trend which shows no sign of abating, cannot be explained by either changes in how the condition is diagnosed or counted, and that environmental factors must be looked at more closely. Published in the January 2009 issue of the journal Epidemiology, the study is entitled “The Rise in Autism and the Role of Age at Diagnosis.” Results from the study suggest that research should shift from genetics to the host of chemicals and infectious microbes in the environment that are likely at the root of changes in the neurodevelopment of California’s children, including pesticides and household chemicals. “It’s time to start looking for the environmental culprits responsible for the remarkable increase in the rate of autism in California,” said UC Davis M.I.N.D. Institute researcher Irva Hertz-Picciotto, PhD, a professor of environmental and occupational health and epidemiology and an internationally respected autism researcher. Dr. Hertz-Picciotto said that many researchers, state officials and advocacy organizations have viewed the rise in autism’s incidence in California with skepticism. The […]

(Beyond Pesticides, December 23, 2008) Last week, the California Department of Pesticide Regulation (DPR) reported that pesticide use declined in California for a second consecutive year in 2007. Approximately 172 million pounds of pesticides were applied statewide, a decrease of nearly 16 million pounds – or 8.4 percent – from 2006. Production agricultural use dropped by more than 11 million pounds, as did almost every other category. Reports in the state are mandatory for agricultural and pest control business applications, while most home, industrial and institutional uses are exempt. “While pesticide use varies year to year based on weather conditions, economics, types of crops, acreage planted and other variable factors, the reduction in 2007 reflects the Department of Pesticide’s efforts to promote pest control through a combination of techniques that pose the lowest risk to public health and the environment” said DPR Director Mary-Ann Warmerdam. “I am especially encouraged to see an across-the-board drop in categories of pesticides with the greatest regulatory concern.” Warmerdam referred to pesticides that have been identified as potential or known carcinogens, reproductive toxins, ground water contaminants, toxic air contaminants and chemicals that disrupt nerve function. All of these high-toxicity categories declined in 2007 as measured […]
