(Beyond Pesticides, June 28, 2010) A new report documents high levels of pesticide drift in the California community of Sisquoc. Poison Gases in the Field: Pesticides put California families in danger, released by Pesticide Action Network North America and local community members, presents results of community air monitoring for fumigant pesticides in the central coast area of California, in Santa Barbara County. Using a simple monitoring device called the Drift Catcher, community members measured levels of a fumigant pesticide above the California Department of Pesticide Regulation’s (DPR) “level of concern” — even when all application rules were followed and no equipment failure occurred. “While we were monitoring the air, there were no violations of the County’s permit – and yet we found we were still breathing chloropicrin at high levels,” says Deby DeWeese, one of the community members who collected air samples. “Clearly the rules and regulations do not protect our families.” The Sisquoc monitoring, conducted during and after a soil fumigation in April 2008, found the pesticide chloropicrin in about half of the 57 air samples collected. Two samples had chloropicrin levels higher than DPR’s 24-hour level of concern for children, and the 19-day average level at one sampling […]

(Beyond Pesticides, June 7, 2010) With thousands of violations cited, the pest control company and applicator responsible for the deaths of two young children are only fined several tens of thousands of dollars, a mere slap on the hand. The Utah Department of Agriculture and Food’s (UDAF) Division of Plant Industry has finally filed multiple charges of violations against Bugman Pest and Lawn, Inc. of Bountiful, Utah, and employee Cole Nocks associated with the February 5, 2010 application of the pesticide Fumitoxin (active ingredient: aluminum phosphide) at the residence of Nathan and Brenda Toone of Layton, Utah that lead to the death of their two daughters ages 15-months and 4 years. In addition to the Layton incident, investigators discovered additional violations of the Utah Pesticide Control Act by the company and other employees. The UDAF seeks to revoke Mr. Nocks’s applicator license and has issued him a $27,000 fine, while Bugman Pest and Lawn, Inc. is fined $32,000. Under law, the UDAF is only allowed to file civil penalties. Investigators determined that on February 5, 2010 applicator Cole Nocks operated in a faulty, careless or negligent manner by misapplying the highly toxic and restricted use pesticide, Fumitoxin. Mr. Nocks’s improper […]

(Beyond Pesticides, May 4, 2010) On April 30, 2010, despite significant cancer and reproductive health risk, especially to farmworkers and people living near agricultural fields, the California Department of Pesticide Regulation (DPR) proposed the use of a new and highly toxic pesticide, methyl iodide, for widespread agricultural use in California. The U.S. Environmental Protection Agency (EPA) registered methyl iodide in 2007 as a replacement for the ozone-depleting pesticide, methyl bromide. Environmental and public health advocates believe that blocking methyl iodide registration in California will prevent its use elsewhere, since the state will account for the vast majority usage and profitability nationwide. Public comments may be sent to [email protected]. If registered, methyl iodide will be used primarily to fumigate and sterilize the California’s strawberry fields, although the pesticide will also be used in nurseries and nut tree production. DPR’s proposal does not require neighbor notification before use of this extremely toxic chemical. As evidenced by California’s thriving organic industry, alternatives to fumigants exist and are in use in California. In a hearing on February 8, 2010, before the California Senate Committee on Food and Agriculture, two panels of California growers and researchers discussed a number of safe and effective alternatives to […]

(Beyond Pesticides, April 8, 2010) The U.S. Environmental Protection Agency (EPA) is requiring new restrictions on aluminum and magnesium phosphide products in an attempt to better protect people, especially children, from dangerous exposures. The new restrictions prohibit all uses of the products around residential areas and increase buffer zones for treatment around non-residential buildings that could be occupied by people or animals from 15 feet to 100 feet. Human exposure to these toxic chemicals, though slightly minimized, would nevertheless continue because of their continued availability for use on athletic fields and playgrounds, around non-residential buildings, and in agricultural production. Phosphide fumigants are known to be highly acutely toxic when ingested or inhaled. Symptoms of mild to moderate acute exposure include nausea, abdominal pain, tightness in chest, excitement, restlessness, agitation and chills. Symptoms of more severe exposure include diarrhea, cyanosis, difficulty breathing, pulmonary edema, respiratory failure, tachycardia (rapid pulse) and hypotension (low blood pressure), dizziness and/or death. Aluminum and magnesium phosphide fumigants are used primarily to control insects in stored grain and other agricultural commodities. They also are used to control burrowing rodents in outdoor agricultural and other non-domestic areas. The fumigants are restricted to use by specially trained pesticide applicators. […]

(Beyond Pesticides, February 11, 2010) Investigators are tying the deaths of 4-year and 15-month old sisters in Layton, Utah to a pesticide that was used to kill voles, small burrowing rodents, in their family’s front yard. The 4-year-old, Rebecca Toone, died Saturday and her sister Rachel died on Tuesday after the family was hospitalized with flu-like symptoms then discharged. The girls went back to the hospital when they fell ill again after returning home. The cause of the deaths has not yet been determined, according to the Utah Medical Examiner’s Office, and toxicology tests are expected to take up to eight weeks to complete. However, investigators say that the chemical may have wafted into the family’s home after an exterminator dropped Fumitoxin, aluminum phosphide, pellets in burrow holes in the lawn on Friday. Upon exposure to moisture in the air, the pellets immediately decompose to phosphine gas. The death of these children and the poisoning of the family raise serious issues about the adequacy of the pesticide’s label restrictions, approved by the U.S. Environmental Protection Agency (EPA), and their enforceability. In the case of aluminum phosphide, EPA has allowed the use that led to these avoidable deaths after proposing to […]

(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, December 1, 2009) A new study published in the November 2009 issue of Occupational and Environmental Medicine, adds rhinitis, the inflammation of the mucous lining of the nose, to the long list of ailments linked to pesticide exposure. “Rhinitis associated with pesticide exposure among commercial pesticide applicators in the Agricultural Health Study,” examined data from 2,245 Iowa commercial pesticide applicators and evaluated the association between rhinitis and 34 pesticides used in the past year. Seventy-four percent of commercial pesticide applicators in the study reported at least one episode of rhinitis in the past year (current rhinitis), compared with about 20-30% of the general population. Pesticide exposure and rhinitis were assessed at enrollment using two self-administered questionnaires. The first, completed at enrollment, obtained detailed information on use of pesticides on the market at the time of enrolment as well as smoking history, current agricultural activity and demographics. The second questionnaire, sent one month later, more detailed information on the pesticides, as well as medical history, including rhinitis, conjunctivitis, sinusitis and asthma. Respondents reported using 16 herbicides, 11 insecticides, five fungicides and two fumigants in the past year. Five of the pesticides were significantly positively associated with current rhinitis: the […]

(Beyond Pesticides, November 5, 2009) The U.S. Environmental Protection Agency (EPA) has rolled out proposed guidance for new pesticide labeling in an effort to reduce off-target spray and dust drift. According to EPA, the actions detailed in the draft Pesticide Registration (PR) Notice on Pesticide Drift Labeling, when implemented, are projected to help improve the clarity and consistency of pesticide labels and help prevent harm from spray drift. The agency is also requesting comment on a petition to evaluate children’s exposure to pesticide drift. Last month, a petition filed by Earthjustice and Farmworker Justice asked EPA to set safety standards protecting children who grow up near farms from the harmful effects of pesticide drift. The groups also asked the agency to adopt an immediate no-spray buffer zone around homes, schools, parks and daycare centers for the most dangerous and drift-prone pesticides. According to the agency, the new instructions are said to prohibit drift that could cause “adverse health or environmental effects,” by evaluating scientific information on risk and exposure based on individual product use patterns on a pesticide-by-pesticide basis. These assessments will help the agency determine whether no-spray buffer zones or other measures, such as restrictions on droplet or particle […]

(Beyond Pesticides, September 29, 2009) A new study reveals that children exposed to agricultural pesticides applied near their home have up to twice the risk of developing the most common form of childhood leukemia, according to the Northern California Cancer Center (NCCC). The study, “Residential proximity to agricultural pesticide applications and childhood acute lymphoblastic leukemia,” published in the October issue of Environmental Research, used a unique California database to reveal an elevated risk in acute lymphoblastic leukemia (ALL) among children living near applications of certain categories of pesticides used in agriculture. The study, led by Rudolph Rull, Ph.D., shows an elevated risk of ALL associated with moderate exposure, but not high exposure, to pesticides classified as organophosphates (odds ratio (OR) 1.6), chlorophenoxy herbicides (OR 2.0), and triazines (OR 1.9), and with agricultural pesticides used as insecticides (OR 1.5) or fumigants (OR 1.7). California is one of the few states in the country that requires active reporting of pesticide applications, including time, place, and the type and amount of pesticide used. For this study, researchers were able to link children’s entire residential histories from birth to the time of case diagnosis to this pesticide-use reporting database and identify agricultural pesticides that […]

(Beyond Pesticides, September 4, 2009) The U.S. Environmental Protection Agency (EPA) fined a Minden, Nevada-based ornamental tree nursery for misusing pesticides contrary to labeling requirements and failing to comply with federal pesticide worker safety laws. Genoa Tree Nursery misused the pesticide Diazinon AG500 during applications in May and June 2008. The company failed to comply with label directions that require it to minimize the risk of exposure by notifying workers and handlers of recent pesticide applications on particular fields, and failed to provide workers with nearest emergency medical care facility information in case of exposure. The applicator also did not receive safety training during the previous five years as required by law. EPA fined Genoa Tree Nursery a mere $5,440 for these violations. “Notifying employees about potentially harmful pesticide exposure is not just a good idea, it’s the law,” said Katherine Taylor, EPA’s Communities and Ecosystems Division associate director for the Pacific Southwest region. “Employers of agricultural workers must ensure their employees are provided with information and protections that minimize the risk of potential exposure to pesticides””failure to do so is a serious violation.” The Nevada Department of Agriculture discovered the violations during a routine inspection in June 2008. The […]

(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, June 19, 2009) Farmworker unions, support groups, and worker advocacy organizations today asked Environmental Protection Agency (EPA) Administrator Lisa P. Jackson to stop the pesticide poisoning of farmworker communities and uphold the Obama administration’s commitment to environmental justice. Citing a long EPA history of “inhumane neglect of toxic pesticide effects on farmworker community health,” the groups asked the Administrator to amend a recent May 2009 decision that allows the continued use of hazardous soil fumigant pesticides. The chemicals when used in chemically treated crop production, such as tomatoes, carrots, strawberries and nuts, escape into the environment and drift into communities where the families and children of farmworkers live and play. The letter, signed by 28 groups from across the country, says that the new fumigants policy “continues an outdated EPA approach to pesticide regulation that adopts unrealistic and unenforceable standards as risk mitigation measures, in an age of safer, greener approaches to agricultural pest management.” EPA announced its decision May 27, 2009 to allow continued use of toxic soil fumigants with modified safety measures, falling far short of safety advocate efforts to adopt more stringent use restrictions and chemical bans. The rule was first proposed in July 2008, […]

(Beyond Pesticides, May 29, 2008) The Environmental Protection Agency (EPA) announced May 27, 2009 modified safety measures for soil fumigant pesticides, falling short of safety advocate efforts to adopt more stringent use restrictions and chemical bans. The new regulations follow a July 10, 2008 proposed rule, which resulted from three years of deliberation. Safety advocates said last July that while substantially better than the past, the proposed regulation fell short in protecting people, workers and the environment and from that perspective this weeks regulation is a disappointment. Advocates believe that the country can do better to phase out uses of highly hazardous chemicals that have devastating impact on exposed workers and communities in which they are used, and advance green technologies and organic practices. Fumigants, which are among the most toxic chemicals used in agriculture, are gases or liquids that are injected or dripped into the soil to sterilize a field before planting. Even with plastic tarps on the soil, fumigants escape from the soil and drift through the air into schools, homes, parks and playgrounds. Strawberries, tomatoes, peppers, carrots and potatoes are some of the major crops for which fumigant use is high. The agency says these measures will […]

(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, 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, February 24, 2009) NIEHS staff scientist Freya Kamel, Ph.D., Harvard School of Public Health professor Chensheng (Alex) Lu, Ph.D., and Wake Forest University’s Center for Worker Health director Thomas Arcury, Ph.D. will speak as Science and Health panelists at Bridge to an Organic Future: Opportunities for health and the environment, the 27th National Pesticide Forum, April 3-4 in Carrboro, NC. Freya Kamel, Ph.D. Freya Kamel’s research interests focus on environmental determinants of neurologic dysfunction and disease, in particular, neurodegenerative disease. Dr. Kamel and her colleagues at the National Institute for Environmental Health Sciences (NIEHS) of the National Institutes of Health (NIH) examined the relationship of farm work-related exposures to subclinical neurobehavioral deficits in farmworkers. Deficits in neurobehavioral performance reflecting cognitive and psychomotor function related to the duration of work experience were seen in former as well as current farmworkers, and decreased performance was related to chronic exposure even in the absence of a history of pesticide poisoning. Thus, long-term experience of farm work is associated with measurable deficits in cognitive and psychomotor function. Dr. Kamel participated in work on the Agricultural Health Study (AHS), a large cohort study of licensed pesticide applicators and their spouses in Iowa and […]

(Beyond Pesticides, January 26, 2009) University of California at Irvine researchers have discovered that sulfuryl fluoride, an insecticide widely used to fumigate termite-infested homes and buildings, stays in the atmosphere at least 30-40 years and perhaps as long as 100 years and is about 4,000 times more efficient than carbon dioxide at trapping heat, though much less of it exists in the atmosphere. This raises concerns as levels have nearly doubled in just the last six years. Prior studies estimated its atmospheric lifetime at as low as five years, grossly underestimating the global warming potential. “Sulfuryl fluoride has a long enough lifetime in the atmosphere that we cannot just close our eyes,” said Mads Sulbaek Andersen, a postdoctoral researcher in the Rowland-Blake laboratory and lead author of the study. “The level in the atmosphere is rising fast, and it doesn’t seem to disappear very quickly.” Its climate impact in California each year equals that of carbon dioxide emitted from about one million vehicles. About 60 percent of the world’s sulfuryl fluoride use occurs in California. The insecticide is pumped into a tent that covers a termite-infested structure. When the tent is removed, the compound escapes into the atmosphere. Sulfuryl fluoride […]

(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 […]

(Beyond Pesticides, October 14, 2008) Exposure to glyphosate or MCPA can more than double one’s risk of developing non-Hodgkin lymphoma (NHL), according to a new epidemiological study published in the October issue of the International Journal of Cancer. The case-control study finds a 2.02 odds ratio (OR) for exposure (two times the chance of contracting the illness) to glyphosate, a 2.81 OR for exposure to MCPA, and a 1.72 OR for exposure to herbicides. According to EPA, glyphosate is the most commonly used pesticide in the U.S. with 103 to 113 million pounds used annually. MCPA is a phenoxyacetic acid pesticide, a family of pesticides that has previously been linked to cancer and includes 2,4-D and mecoprop (MCPP). NHL is a cancer of the immune system. There are several different types of NHL, which are differentiated by the type of immune cell that is cancerous, the characteristics of the cancerous cell, and different genetic mutations of the cancerous cells. Treatment for NHL varies depending on NHL type, patient age, and other existing medical conditions. The incidence of NHL has been increasing over the past several decades. The link between pesticides and cancer has long been a concern. While agriculture has […]

(Beyond Pesticides, September 24, 2008) Pesticides used on peach orchards over 50 years ago have been detected in the groundwater of three North Carolina counties. Tests have detected 117 tainted wells in Montgomery, Richmond and Moore counties in the past year, 77 of those at unsafe levels. Public Health officials are scrambling to deliver safe water to those whose wells have been contaminated. However, the number of contaminated wells is forecasted to increase as more residents opt to have their groundwater tested, as the news of tainted wells continues to spread. Many residents are also wondering how they have been impacted as a result of their exposure to the tainted water. Local officials are also worried over how far and wide the contamination has spread. Contamination levels as high as 55 times the federal safe drinking-water standard have been detected. Households where concentrations are highest have been told not to drink or cook with their well water, and limit showers to 10 minutes. Peach orchards now grow on a modest 1,350 acres in North Carolina, but production in 1941 was 12 times greater. The chemicals now detected in groundwater were first used in the 1950s and include ethylene dibromide (EDB) […]

(Beyond Pesticides, July 31, 2008) The Third International Biofumigation Symposium took place in Australia July 21-25, 2008, highlighting new scientific advancements in the age old practice of planting crops in the brassica family (radish, mustard, etc.) prior to growing other crops to control diseases, insects, and weeds. Research in this area reveals that in many cases, “biofumigation,” as it is called, provides disease and pest control comparable to that of pesticides commonly used as soil fumigants, and does not have the negative health and environmental effects associated with these fumigants. Growing interest in biofumigation is spurred by the international phase-out of the toxic soil fumigant methyl bromide (for its role in ozone depletion) under the Montreal Protocol. Unfortunately, even though the environmental and health risks of methyl bromide and other soil fumigants have been documented, and non-toxic alternatives such as biofumigation exist, the U.S. Environmental Protection Agency (EPA) has essentially ignored the Montreal Protocol and continued to allow the use of methyl bromide under “exemptions.” In the most recent EPA action on the subject, the agency released proposed rules and risk mitigation measures for five toxic soil fumigants on July 10, 2008. These rules fall short of the hopes of […]

(Beyond Pesticides, July 15, 2008) After three years of deliberation, the U.S. Environmental Protection Agency (EPA) proposed new rules for five highly toxic fumigant pesticides on July 10, 2008. Environmental health, community and farmworker groups say the rules, while substantially better than the past, still fall short of protecting people, workers and the environment. The rules will be published in the Federal Register on July 17, 2008.The fumigant review, mandated by the 1996 Food Quality Protection Act, was conducted as a combined evaluation of five commonly used fumigants, called the “Fumigant Cluster Assessment.” The five fumigants included in the assessment are methyl bromide, metam sodium, metam potassium, dazomet, and chloropicrin. Methyl bromide was slated for phaseout by January 2005 under the Montreal Protocol because it is a potent ozone depletor, but the Bush Administration has sought annual “critical use exemptions,” keeping it on the market. Fumigants, which are among the most toxic chemicals used in agriculture, are gases or liquids that are injected or dripped into the soil to sterilize a field before planting. Even with plastic tarps on the soil, fumigants escape from the soil and drift through the air into schools, homes, parks and playgrounds. Strawberries, tomatoes, peppers, […]

(Beyond Pesticides, December 4, 2007) On November 29, 2007, the California Department of Pesticide Regulation (DPR) reported 2006 pesticide use statistics that showed continued progress toward less pesticide use statewide. However, strawberry growers increased their reliance the highly toxic, ozone depleting fumigant methyl bromide. Overall statewide pesticide use declined by nearly six million pounds from 2005 to 2006 (from 195.3 million to 189.6 million). While use increased in landscape maintenance, public health and other categories, production agriculture saw a 10 million pound drop. Use of many high-toxicity chemicals, including carcinogens, neurotoxic pesticides and chemicals linked to reproductive effects dropped for the third consecutive year. “DPR works hard to promote least-toxic pest management, and our efforts are paying off,” said DPR director Mary-Ann Warmerdam. “At the same time, we will continue to strive for long-term success in pest management, and we have more work to do.” On the other hand, the Los Angeles Times reports that state strawberry growers, primarily around Oxnard and in the Salinas and Watsonville areas, applied fumigants to 5,000 more acres, using 132 more tons of the chemicals than in the previous year. That is a 9% increase in acreage treated and a 3% increase in tonnage. […]
