(Beyond Pesticides, May 21, 2024) In a first-of-its kind series of biomonitoring studies published in Agrochemicals, researchers identified the presence of the herbicides dicamba and 2,4-D in all pregnant participants from both cohorts in 2010-2012 and 2020-2022. The findings from this research are not surprising given the explosion of toxic petrochemical pesticides in the Midwest region of the United States. “The overall level of dicamba use (kilograms applied in one hundred thousands) in the U.S. has increased for soybeans since 2015 and slightly increased for cotton and corn,” the authors report, based on U.S. Department of Agriculture National Agriculture Statistics Service surveys. “The overall level of 2,4-D use (kilograms applied in one hundred thousands) in the U.S. was highest in 2010 for wheat, soybeans, and corn. The amount of 2,4-D applied increased the most for soybeans and corn from 2010 to 2020.” The researchers focused on the states of Illinois, Indiana, and Ohio, given the increase in dicamba and 2,4-D during the study period for both cohorts (2010-2022). The researchers are based at Indiana University School of Medicine in the Department of Biostatistics and Health Data Science and Department of Obstetrics and Gynecology, Quebec Toxicology Center within the Institut national […]

(Beyond Pesticides, April 17, 2024) With headlines drawing public attention to the contamination of drinking water after years of federal government neglect, the U.S. Environmental Protection Agency (EPA) announced on April 10 new standards to reduce public exposure to PFAS, or per- and polyfluoroalkyl substances, commonly referred to as “forever chemicals” because of their persistence. EPA has finalized a National Primary Drinking Water Regulation (NPDWR) for six PFAS, including PFOA and PFOS, which EPA has recognized have no safe level of exposure, regulating new chemicals for the first time since the 1996 amendments to the Safe Drinking Water Act (SDWA). PFAS persistence and bioaccumulation in humans, wildlife, and the environment is due to the strength of a resulting fluorine–carbon atom bond. PFAS contamination of drinking water, surface and groundwater, waterways, soils, and the food supply—among other resources—is ubiquitous worldwide. PFAS is used in everyday products, including cookware, clothes, carpets, as an anti-sticking and anti-stain agent, in plastics, machinery, and as a pesticide. The action was welcomed by environmentalists and public health advocates as an important step but left many concerned that any level of exposure to these chemicals is unacceptable and critical of EPA’s ongoing failure to act despite years […]

(Beyond Pesticides, February 21, 2023) The recent train derailment in East Palestine, Ohio, should be a reminder to all of us that problems with our reliance on toxic chemicals go beyond broadcasting them on fields. In order to get pesticides to their point of use, toxic precursors and ingredients must be transported. Toxic waste products are also delivered to a location where they may be burned or deposited in a landfill. In weighing the hazards of toxic pesticides, these ancillary hazards should also be considered. Tell EPA and Congress that all impacts of toxic chemicals—from cradle to grave—must be considered before allowing their use.      The freight train that derailed February 3, 2023 in East Palestine was carrying a number of toxic chemicals. EPA notified the railroad, “EPA has spent, or is considering spending, public funds to investigate and control releases of hazardous substances or potential releases of hazardous substances at the Site. Based on information presently available to EPA, EPA has determined that Norfolk Southern Railway Company (Norfolk Southern or “you”) may be responsible under CERCLA [Comprehensive Environmental Response, Compensation, and Liability Act–Superfund] for cleanup of the Site or costs EPA has incurred in cleaning up the Site.” But […]

(Beyond Pesticides, September 14, 2016) According to a recent study by the U.S. Geological Survey (USGS), high concentrations of dioxins and furans have been detected in tree swallow eggs collected near several sites around the Great Lakes. Other chemicals detected include polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs), which were at background levels. The study is part of efforts to clean up a toxic chemical legacy around the Great Lakes, and the researchers believe their results are critical to regulators to assess “bird or animal deformity or reproductive problems” The study, “Concentrations and spatial patterns of organic contaminants in tree swallow (Tachycineta bicolor) eggs at United States and binational Great Lakes Areas of Concern, 2010—2015,” used tree swallows to quantify current exposure to organic contaminants across all five Great Lakes including 59 sites within 27  Areas of Concern (AOCs)  and 10 nearby  locations. The Great Lakes Areas of Concern refers to a U.S.-Canada  Great Lakes Water Quality Agreement  (Annex 1 of the 2012 Protocol) that  defines AOCs as “geographic areas designated by the Parties where significant  impairment of beneficial uses  has occurred as a result of human activities at the local level.” An AOC is a location that has […]

(Beyond Pesticides June 4, 2015) Another study has found links between a commonly used household pesticide and attention deficit hyperactivity disorder (ADHD) in children and young teens. Researchers at Cincinnati Children’s Hospital Medical Center found an association between pyrethroid pesticide exposure and ADHD, particularly in terms of hyperactivity and impulsivity. These results reinforce the findings of a study led by a research team at Rutgers University earlier this year that found links between the pesticide deltamethrin and ADHD. In 2001, over concerns about adverse health consequences, the U.S.  Environmental Protection Agency banned several commonly used organophosphate (organic compounds containing phosphorus) pesticides from residential use due to the chemicals neurotoxic properties. The ban led to the increased use of pyrethroid pesticides, which are now the most commonly used pesticides for residential pest control and public health purposes. Pyrethroids, like deltamethrin, are commonly used in the home,  office buildings,  and on vegetable crops, gardens, lawns and golf courses. This shift to predominantly using pyrethroids is troubling, as they have oft been promoted as a safer choice than banned organophosphates, despite the fact that they pose many real threats to human health. Many recent studies show significant concern with this class of chemicals, […]

(Beyond Pesticides, April 24, 2014) Reports of honey bee deaths have been emerging around the nation: from bee deaths in California’s almond groves and ”˜mysterious’ road-side bee deaths in Oregon, to astronomical overwintering losses in Ohio. The reports are intensifying the ecological crises of Colony Collapse Disorder (CCD) ””a phenomenon typified by the mass abandonment of hives and bee die-off. CCD poses significant issues for many agricultural crops, such as almonds, apples, cherries and blueberries, that are almost completely reliant on honey bees for their pollination services. In California, a total of 80,000 dead or damaged bee hives were reported after pollinating almond trees in the San Joaquin Valley, a region that is known for its agricultural productivity. Beekeepers have pointed to pesticides as the primary culprit. Almond pollination in California requires an army of 1,300 commercial beekeepers from around the nation. However, this year beekeepers have seen higher damages to hives than usual. Damage to the honey bee hives this spring has been so pronounced that the U.S. Environmental Protection Agency (EPA) convened an impromptu meeting with beekeepers in Los Banos, California. The meeting brought together 75 beekeepers who testified that 75 percent of their hives showed severe damage […]

(Beyond Pesticides, November 15, 2013) Recommended measures to reduce Lake Erie’s phosphorous, a fertilizer ingredient that feeds algae and steals aquatic oxygen, was released Wednesday by the Lake Erie Task Force II. The collaboration of officials, scientists, and interest groups identified agriculture as the primary contributor to phosphorous loading in Lake Erie, recommending that the nutrient runoff into northwestern Ohio tributaries and to the lake be cut by 40 percent. Fertilizer runoff not only causes unsightly and odiferous algal blooms, it can also severely harm aquatic wildlife. Once algae dies off, aerobic bacteria consume the dead algae resulting in dangerously low oxygen “dead zones.” Lake Erie is particularly prone to algal blooms in part because it is the southern-most, shallowest and warmest of the Great Lakes, but also because surrounded by prime agricultural land. The task force’s report contains 20 recommendations for reducing phosphorous inputs into Lake Erie, including continued nutrient monitoring, developing dedicated funds for research, updating the phosphorous index farmers use to guide their fertilizer applications, promoting management practices that support living roots year round, and avoiding fertilizer application on frozen ground or before rainy weather. Unfortunately, the task force is recommending strictly voluntary measures and many environmental […]

(Beyond Pesticides, July 5, 2013) A bill recently introduced in the Ohio State Senate would grant state agencies new regulatory powers intended to stunt the spread of toxic blue green algae in Lake Erie. Senate Bill 150, introduced by Republican State Senator  Cliff Hite, will empower the Ohio Department of Natural Resources (ODNR) and Ohio Department of Agriculture (ODA) to require reductions in the amount of fertilizer runoff that is produced by farms. Currently the state lacks authority to limit commercial fertilizer runoff. Swift action is needed as blue green algae blooms, which feed off phosphorus in fertilizer runoff, have increased dramatically in Lake Erie since the mid-1990’s. The proposed legislation would provide ODNR the authority to cite farmers who allow fertilizers to runoff their field. Under the proposed bill, the Chief of ODNR would issue orders to farmers to comply with technical standards, to be created by ODNR,  that “achieve a level of management and conservation practices that will…abate the degradations of the waters of the state by soil amendments.”  Under this legislation, farmers will have to undergo training and receive a certificate from ODA to apply fertilizers and manure. “Farmers would apply for a fertilizer certificate in the […]

(Beyond Pesticides, April 18, 2013) With hotter and more frequent extreme weather events, scientists say harmful algal blooms caused by pesticides and fertilizer inputs will strike more often in water bodies like Lake Erie, to the detriment of aquatic life and surrounding wildlife. All trends, show that the conditions that caused Lake Erie’s 2011 algal blooms will continue recurring. The algal blooms, which cause bright green scum that completely covers the Western part of Lake Erie, occurs from mid-July to October, in part because of farming practices surrounding the Lake and in part due to climate change. Ecologist Thomas Bridgeman, Ph.D.  at the University of Toledo contributed to these findings in this month’s publication of the Proceedings of the National Academy of Science entitled “Record-setting algal blooms in Lake Erie caused by meteorological trends consistent with expected future conditions. “The 2011 bloom was a catastrophe. But it could become the new normal if we don’t do anything” said Dr. Bridgeman. Importantly, the study concludes that “long-term trends in agricultural practices are consistent with increasing phosphorus loading to the western basin of the lake, and that these trends, coupled with meteorological conditions in spring 2011, produced record-breaking nutrient loads.” In short, […]

(Beyond Pesticides, January 24, 2013) Checks are now being sent to 1,085 community water systems across the U.S. in the final phase of a $105 million settlement with Syngenta, the largest manufacturer of the toxic weed killer atrazine. The class action settlement, City of Greenville v. Syngenta Crop Protection, Inc., Case No.: 3:10-cv-00188-JPG-PMF, stems from a lawsuit spanning eight years and is meant to help reimburse communities for past expenses associated with atrazine removal. “Science has been fighting an uphill battle against giant pesticide manufacturers like Syngenta who claim that a little weed killer in your drinking water won’t hurt you. Independent scientists now believe that even trace amounts can harm you and your children for generations to come,” the lead plaintiff’s lawyer Stephen M. Tillery told the media. Atrazine is used nationwide to kill broadleaf and grassy weeds, primarily in corn crops. A potent toxicant, it is the most prevalent herbicide found in Minnesota’s waters. It is widely applied in the midwestern states and has been found in the drinking water supplies in the Midwest at high levels. Researchers at the Centers for Disease Control (CDC) have determined that previous studies that assessed population-based exposure to atrazine were significantly […]

(Beyond Pesticides, April 17, 2012) Last week, Ohio’s Cuyahoga County Council voted to limit the use of chemical insecticides, weed killers and other pesticides on county property. According to the Cleveland Plain Dealer, the restrictions will apply to the county’s 66 buildings, their lawns and the wide swaths of open space at Whiskey Island and the Cuyahoga County Airport. In describing the ordinance Councilman Julian Rogers said, “[County pest managers] have to focus on using techniques that will specifically target the pests they’re looking to eliminate and will have the least amount of impact to other organisms, including humans.” Cuyahoga County is Ohio’s most populous county. “This is a watershed ordinance, certainly for the state of Ohio,” said Barry Zucker, executive director of Beyond Pesticides Ohio and long-time advocate for this type of county-wide ordinance. “This is a terrific achievement and a tremendous model for other communities in Ohio and the rest of the nation.” People in the county have long recognized the dangers posed by pesticides and the availability of viable alternatives. Under the leadership of Beyond Pesticides Ohio, the town of Cleveland Heights became the first municipality in the nation to legislatively prohibit the application of lawn chemicals […]

(Beyond Pesticides, April 9, 2012) A new study finds that exposure of pregnant women to organophosphate (OP) pesticides —a widely used class of pesticides in North American agriculture— may affect both length of pregnancy and birth weight. Environmental Health Perspectives published the paper, “Associations of Prenatal Exposure to Organophosphate Pesticide Metabolites,” last Thursday, April 5, 2012. The study, by a Simon Fraser University researcher, finds that the population of 306 women in Cincinnati, Ohio, is representative of the type of exposures most North American women and their children experience. Although the use of OPs in Canada and the U.S. has declined in recent years, exposures remain widespread, and these findings add to growing evidence about the harmful effects of low-level exposures to environmental toxicants. The researchers collected urine from each of the women in Cincinnati twice during their pregnancies for organophosphate metabolites as well as other factors that could influence the fetus’ health, including exposure to second hand smoke, race, and poverty. Women with higher levels of organophosphates were found to have pregnancies that were three to four days shorter and babies that were about â…“ pound lighter on average than women with lower levels of pesticides. “For an individual […]

(Beyond Pesticides, November 3, 2011) The State of Ohio announced Friday, October 28 it will rescind a regulation that has prohibited organic dairy product labeling from declaring that antibiotics, pesticides or synthetic hormones are not used. In a lawsuit filed by the Organic Trade Association (OTA), the Sixth Circuit Court of Appeals found that proposed restrictions violate the First Amendment of the constitution. As a result, Ohio has abandoned the rule, thus allowing labeling to proudly state that organic dairy products are produced in accordance with federal organic standards under the Organic Foods Production Act, and therefore without the use of synthetic growth hormones or antibiotics. “This is significant for all of us who support what the organic foods are about, and for consumers who carefully read food labels to find out what’s in their food and how it’s produced,” said Christine Bushway, Executive Director and CEO for OTA. “The Sixth Circuit opinion made it clear that states cannot unduly restrict organic labels or consumers’ right to know how their food is produced, and the State of Ohio’s actions today make it clear that the fight to keep labels accurate by OTA, its members, farmers, and consumers was worth it.” […]

(Beyond Pesticides, October 27, 2011) Forty-seven students from Edgewood Middle School in St. Clair Township, Ohio, reportedly fell ill after the school’s hired pest control company sprayed the herbicide Momentum, which contains the toxic ingredients 2,4-D, triclopyr and clopyralid, on nearby playing fields to treat for clover and other weeds. The incident and others like it demonstrate the need for a comprehensive national policy to protect children from harmful and unnecessary exposure to toxic chemicals. Six students were taken to nearby hospitals and twenty-one students total were treated for symptoms, including headaches, breathing difficulties, nausea and dizziness. Children are especially sensitive and vulnerable to pesticides because of their rapid development and behavior patterns. Adverse health effects, such as nausea, dizziness, respiratory problems, headaches, rashes, and mental disorientation, may appear even if a pesticide is applied according to label directions, which may have been the case in this situation. Pesticide exposure can have long-term adverse effects, including damage to a child’s neurological, respiratory, immune, and endocrine system and increased asthma symptoms. Studies show that children living in households where pesticides are used suffer elevated rates of leukemia, brain cancer, and soft tissue sarcoma. For more information, see Beyond Pesticides’ fact sheet, […]

(Beyond Pesticides, April 19, 2011) On Saturday, April 16, the Ohio House of Representatives unanimously (97-0) approved a resolution sponsored by State Representative Dale Mallory (D-Cincinnati) regarding bedbugs and propoxur, asking Congress to help convince the U.S. Environmental Protection Agency (EPA) to approve the emergency use of the toxic pesticide. Propoxur, a neurotoxin and probable human carcinogen, has been canceled for indoor residential uses due to the unacceptable risks posed to children’s health and should not be used for indoor treatment. Resolution HR 31, however, urges the use of an emergency exemption under federal law to control bedbugs, a follow-up to an earlier request in 2010. The resolution seeks to invoke a so-called Section 18 emergency use permit , a controversial loophole in the Federal Insecticide Fungicide and Rodenticide Act (FIFRA) that allows for unregistered uses of a pesticide, and in many cases unregistered pesticides, under “emergency circumstances.” In a letter to Administrator Lisa Jackson, dated April 19, 2010, Ohio Governor Ted Strickland supported the state’s request for the exemption claiming, “Without the use of propoxur, there is very little that can be done to meaningfully stop the spread of bed bug infestations.” Environmental and public health groups, including Beyond […]

(Beyond Pesticide, June 11, 2010) The Environmental Protection Agency (EPA) has refused the state of Ohio’s request for an emergency exemption to use the restricted pesticide propoxur in residential settings for control of bed bugs, stating that the chemical “presents unreasonable risk.” Propoxur is a highly toxic, broad spectrum insecticide. All indoor residential uses of this known neurotoxic chemical and possible carcinogen were voluntarily canceled in 2007. The Ohio Department of Agriculture, deeming the increases in bed bug infestations an emergency, requested an exemption to use propoxur in residential areas and in May the Ohio Senate’s Environment and Natural Resources Committee adopted a unanimous resolution urging the EPA to grant it. Beyond Pesticides, with coalition of environmental and public health groups, opposed the request and asked EPA to deny the exemption, citing the serious public health threat associated with the chemical, as well as the availability of alternatives. EPA determined “the requested use presents an unacceptable risk,” according to Administrator Lisa Jackson, in a letter to Ohio Governor Ted Strickland dated June 2, 2010. “Although EPA recognizes the severe and urgent challenges that Ohio is facing from bed bugs, the results of the risk assessment do not support the necessary […]

(Beyond Pesticides, April 20, 2010) Communities from six states filed a lawsuit last month in the U.S. District Court for the Southern District of Illinois against Swiss chemical giant Syngenta AG and its American counterpart Syngenta Crop Protection, Inc., the makers of Atrazine. The 16 municipalities in the states of Kansas, Illinois, Indiana, Ohio, Missouri, and Iowa want Syngenta to pay for the expensive carbon filters needed to remove atrazine from their drinking water supply. The United States’ largest private water utility, American Water Company, has also joined the suit, representing 28 additional communities. Atrazine is used to control broad leaf weeds and annual grasses in crops, golf courses, and even residential lawns. It is used extensively for broad leaf weed control in corn. The herbicide does not cling to soil particles, but washes into surface water or leaches into groundwater, and then finds its way into municipal drinking water. It has been linked to a myriad of health problems in humans including disruption of hormone activity, birth defects, and cancer. Atrazine is also a major threat to wildlife. It harms the immune, hormone, and reproductive systems of aquatic animals. Fish and amphibians exposed to atrazine can exhibit hermaphrodism. Male […]

(Beyond Pesticides, November 13, 2009) The Ohio Department of Agriculture is asking the U.S. Environmental Protection Agency (EPA) to allow an unregistered use of the neurotoxic and cancer causing insecticide propoxur in homes to fight bedbugs in what state officials are describing as an ”˜emergency’ situation. The chemical, o-isopropoxyphenyl methylcarbamate, is in the carbamate family and classified as a probable human carcinogen (Group B2) by EPA, and listed as a known human carcinogen by the state of California. Though EPA allows emergency exemptions for unregistered pesticide uses in agriculture and for public health reasons under a controversial waiver program (Section 18, Federal Insecticide, Fungicide and Rodenticide Act, 40 CFR Part 166), it rarely issues such an exemption for an indoor pesticide use. Columbus, Cleveland, and Cincinnati are all experiencing a surge of bed bug infestations. According to Richard Pollack, a Harvard University public health entomologist, this is probably due to the fact that bedbugs are becoming resistant to many pesticide products that are used today. The use of broad spectrum insecticides, which kill common household insects such as cockroaches, ants and other insects including bed bugs, has resulted in insect resistance to these chemicals. Many of the chemicals used against […]

(Beyond Pesticides, November 3, 2008) A new study, Pyrethroid pesticides and their metabolites in vacuum cleaner dust collected from homes and day-care centers (doi:10.1016/j.envres.2008.07.022), by the U.S. Environmental Protection Agency’s (EPA) National Exposure Research Laboratory finds concentrations of 13 synthetic pyrethroids and their degradates in indoor dust collected from homes and childcare centers in North Carolina and Ohio. The study results show the extent to which hazardous pesticides are present in indoor environments and threaten the public’s health, especially the health of children. With 85 vacuum cleaner bags analyzed, permethrin was present in all 85 dust samples, at least one pyrethroid pesticide was found in 69 samples and phenothrin was found in 36 samples. According to the study findings published in the November issue of the journal Environmental Research, the median concentration of permethrin in the samples is 1454ng/g of dust. Excluding permethrin, pyrethroid conectrations are less than or equal to 100ng/g of dust. The majority of the metabolites are present in more than half of the dust samples. This is not the first time researchers have found pesticides in dust in homes. A study published in the International Journal of Hygiene and Environmental Health (208: 193-199) also found that […]
