(Beyond Pesticides, August 14, 2024) Pesticide exposure is linked to negative birth outcomes in a recent study in the American Journal of Epidemiology. This study adds to that body of science, but is novel research since, “Epidemiological studies of pesticide exposures and stillbirth in the United States have not been published in the past two decades, a time period that has seen dramatic changes in pesticide use compared to the 20th century,” the authors state. The study analyzes Arizona pesticide use records and birth certificates from 2006-2020. Researchers correlate mothers living within 500 meters of any pyrethroid, organophosphate (OP), or carbamate insecticide applications during specific windows before and during pregnancy with stillbirth. The authors focus on exposure during the prenatal period, as it is a susceptible time frame in which any contact with pesticides can negatively impact health. Numerous studies report several adverse birth and childhood outcomes with prenatal exposure. To link pesticide exposure and negative birth outcomes, Arizona records that encompass 1,237,750 births, 2,290 stillbirths, and 27 pesticides were analyzed. The authors “evaluate associations of pyrethroids, OPs, and carbamate insecticides with stillbirth by using data from the Arizona Pregnant women’s Environment and Reproductive outcomes Study (Az-PEARS), a project that […]

(Beyond Pesticides, February 13, 2024) Last week, the United States District Court for the District of Arizona struck down the U.S. Environmental Protection Agency’s (EPA) 2021 approval of three dicamba-based herbicides. This is the second lawsuit since 2020 to call out EPA’s violation to both the Endangered Species Act (ESA) and the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to authorize the use of over-the-top (OTT) dicamba-based herbicide products from Bayer and other petrochemical pesticide companies. This rejection of dicamba-based herbicides fuels advocates’ push for stronger regulatory actions by EPA for all petrochemical pesticides and their push for the more widespread adoption of organic practices that do not use these chemicals. The case was filed by Center for Food Safety (CFS), Center for Biological Diversity, National Family Farm Coalition, and Pesticide Action Network North America. Beyond Pesticides has covered the dicamba tragedy for years, including the EPA Office of the Inspector General’s critical 2021 report, EPA Deviated from its Typical Procedures in Its 2018 Dicamba Pesticide Registration Decision. The report identifies EPA’s abandonment of science and assault on agency integrity. In addition to citing adverse impact on nontarget crops and the environment, the Court zeroes in on EPA’s failure to adequately manage […]

(Beyond Pesticides, June 28, 2022) There is a strong connection between pesticide use and cancer rates in the Western United States, finds research recently published by scientists at University of Idaho and Northern Arizona University. Two studies (here and here) published in the peer-reviewed journal GeoHealth used geospatial data and publicly available pesticide databases to uncover the relationship between chemical heavy agricultural practices and cancer in both adults and children. As the rate of chronic diseases like cancer continue to increase in the United States, and more and more studies find these diseases to be pesticide-induced, it is imperative for the public to put increased pressure on regulators and lawmakers to enact meaningful measures that eliminate pesticide use and the hazards these chemicals pose. Of the two studies conducted by the research team, the first study modeled the connection between pesticide use and cancer incidence for adults and children in 11 western states (Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming), while the second study focuses on childhood cancer rates in Idaho’s 44 counties. Both studies utilized databases established by public entities, including U.S. Geological Survey (USGS) Pesticide National Synthesis Project database, EPA Pesticide Industry […]

(Beyond Pesticides, October 7, 2021) The Arizona State Auditor General reports a lack of groundwater monitoring for pesticides and other contaminants by the Arizona Department of Environmental Quality (ADEQ). For over six years, the agency failed to monitor groundwater and soil for agricultural pesticide contamination. Furthermore, the agency did not implement key groundwater monitoring processes over four years, despite law requirements. This lack of waterway monitoring resulted in an increased number of impaired surface waters across the state.  Pesticide contamination in waterways is historically commonplace and widespread throughout U.S. rivers and streams, with at least five or more different pesticides present in 90 percent of water samples. Thousands of tons of pesticides enter waterways (e.g., rivers, streams, lakes, oceans) around the U.S. from agricultural and nonagricultural sources, contaminating essential drinking water sources, such as surface water and groundwater. Reports like these are essential in determining appropriate regulatory action to protect human, animal, and environmental health from chemical toxicant contamination. The report states, “[The] Department has not developed all required aquifer water quality standards, conducted key ongoing groundwater monitoring of the State’s aquifers, monitored for agricultural pesticides in groundwater and surrounding soil, or reduced the number of impaired surface waters in the State, limiting its […]

(Beyond Pesticides, March 14, 2014) The U.S. Environmental Protection Agency (EPA) announced this week  three grants to universities in Texas, Michigan, and Arizona to implement integrated pest management (IPM) practices, reigniting the debate on whether pesticide dependency in many, if not most, IPM systems is warranted given techniques that have eliminated  toxic pesticide use. Are these programs moving pest management in the right direction, as strong IPM measures offer the opportunity to eliminate the use of pesticides, or is the IPM systems unnecessarily using pesticides that can be replaced by  management practices that exclude pest entryways, adopt sanitation and cleaning practices to eliminate pest conducive conditions, and when necessary, as a last resort, use carefully defined least-toxic chemicals. One of the grants, awarded to Texas A&M Agrilife Extension, will be utilized to develop a central, online source for materials  providing school districts with important information and tools to implement an IPM program. The project’s goal within the three year  grant  period  is to reach  one percent of schools  or 552,350 students of the estimated 49 million children attending U.S. public schools in 15,000 school districts. Another grant was awarded to University of Arizona, with the goal of developing and implementing […]

(Beyond Pesticides, September 20, 2010) California-based discount retailer 99 Cents Only Stores Inc. has been fined over $400,000 for selling three household products containing unregistered or mislabeled pesticides. It is the largest contested penalty ever handed down by EPA. According to EPA, the retailer continued to sell the products even after being notified that they were violating regulations. EPA found 99 Cents Only Stores were selling products in violation of the Federal Insecticide Fungicide and Rodenticide Act (FIFRA) during a routine inspection in 2004. Subsequent inspections up until 2008 found additional problems resulting in a total of 166 separate violations. Originally. EPA handed down a $1 million fine. 99 Cents Only Stores Inc decided to contest the penalty. These types of fines are rarely contested. In the end, EPA Administrative Law Judge Susan Biro ruled the company would pay a fine of $409,490, declaring the retailer’s management had a “culture of indifference.” Of the 166 violations committed by 99 Cents Only stores Inc., 164 were related to a household cleaner and sanitizer imported from Mexico called Bref Limpieza y Disinfeccion Total con Densicloro which translates into “Bref Complete Cleaning and Disinfection with Densicloro.” The product had pesticidal claims on the […]

(Beyond Pesticides, August 3, 2010) A new study shows that due to a flaw in standard risk assessments, which consider toxic effects at fixed exposure times, the risks posed by the neonicotinoid pesticides imidacloprid and thiacloprid are likely to be underestimated. The authors believe that minute quantities of imidicloprid may be playing a much larger role in killing bees over extended periods of time than previously thought. The study, “The significance of the Druckrey—KĂĽpfmĂĽller equation for risk assessment””The toxicity of neonicotinoid insecticides to arthropods is reinforced by exposure time,” was published online July 23, 2010 in the journal Toxicology. The authors believe that standard risk assessment calculations underestimate toxicity because they do not accurately account for the interplay of time and level of exposure. According the study: The essence of the Druckrey—KĂĽpfmĂĽller equation states that the total dose required to produce the same effect decreases with decreasing exposure levels, even though the exposure times required to produce the same effect increase with decreasing exposure levels. Druckrey and KĂĽpfmĂĽller inferred that if both receptor binding and the effect are irreversible, exposure time would reinforce the effect. The Druckrey—KĂĽpfmĂĽller equation explains why toxicity may occur after prolonged exposure to very low toxicant […]

(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 […]
