Ecological Mystery Unravels, With Toxic Pesticide Use at the Center

(Beyond Pesticides, May 12, 2021) Earlier this year, a team of scientists solved an ecological mystery that had persisted for decades. Throughout the southeastern United States, bald eagles and other top-level avian predators were experiencing mass deaths from a disease known as vacuolar myelinopathy (VM), a neurological ailment that causes lesions in affected animal’s brains. Scientists identified the source of the exposure as a cyanobacteria growing on an invasive weed, but up until now, did not know how the bacterium caused disease. Now, scientists have determined that the chemical bromine, likely introduced by brominated herbicides in attempts to manage the invasive species, is the trigger for the production of the cyanobacteria’s neurotoxin. In the mid-1990s, over 70 bald eagles died in Arkansas’s DeGray Lake over the course of two years. The event was the largest mass mortality of eagles recorded. Scientists identified the disease as vacuolar myelinopathy, and through the course of several years were able to determine that the disease generally affected birds in the built environment, near artificial bodies of water with high levels of aquatic plant life. Waterfowl and other bird species were found to develop lesions in lakes where there was an ongoing VM outbreak. Evidence […]

Glyphosate-Based Herbicides and Sustainable Agriculture Do Not Mix!

(Beyond Pesticides, April 29, 2021) Glyphosate-based herbicides (GBHs) are incompatible with sustainable agriculture goals, according to a recent scientific literature analysis by scientists at Tufts University, Massachusetts. Glyphosate is the most commonly used pesticide active ingredient worldwide, appearing in many herbicide formulas, including Bayer’s (formerly Monsanto) RoundupTM. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate. However, studies demonstrate glyphosate is the main contributor to human, biotic, and ecosystem harms as toxicities from herbicides are now double what it was in 2004.  The National Academy of Sciences identifies four goals of sustainable agriculture—productivity, economics, environment, and social well-being for future generations. However, pesticides like glyphosate are ubiquitous in the environment, putting the health, economy, and food/resources for future generations at risk. Therefore, research like this is vital for understanding how chemical use can undermine sustainable agriculture goals to protect humans, animals, and environmental health. Researchers note, “[W]hether or not GBHs are viewed as essential or unessential to contemporary agriculture, and notwithstanding their role in non-tillage agriculture, this study shows that glyphosate-based herbicides do not reach the bar of agricultural sustainability, with respect to humans and the environment, making the system they are part of unsustainable.” Researchers thoroughly examined […]

Roundup Shown to Kill Bees—But Not How You Might Expect

(Beyond Pesticides, April 20, 2021) Roundup products manufactured by Bayer-Monsanto kill exposed bumblebees at high rates, according to a new study published in the Journal of Applied Ecology, which points to undisclosed inert ingredients (those that typically make up a majority of the product formulation) as the primary culprit. Roundup products have become synonymous with their main active ingredient glyphosate, but Bayer-Monsanto has been quietly reformulating its flagship product with different herbicides in a likely attempt to rebrand as glyphosate cancer lawsuits drag down the company’s performance. The new study reveals that these new Roundup products present the same hazards to pollinators as glyphosate-based formulations, raising important questions about the pesticide regulatory process. Researchers based at Royal Holloway University of London, UK conducted the present study to better understand the hazards posed by herbicides often characterized as “bee safe” to the public. To do so, 10 healthy bumblebee (Bombus spp) colonies were retained, split into small groups, and sprayed with a particular herbicide. Four different herbicide products were employed, including: i) Fast Action RoundupÂŽ Ready‐To‐Use (containing glyphosate); ii) RoundupÂŽ Speed Ultra (containing acetic acid and no glyphosate); iii) WeedolÂŽ Gun! Rootkill Plus (containing glyphosate) and; iv) RoundupÂŽ ProActive (contains glyphosate […]

Implications for Human Health: Glyphosate-Related Soil Erosion Re-Releases Toxic Pesticides from Soil

(Beyond Pesticides, March 4, 2021) A new study finds glyphosate use stimulates soil erosion responsible for releasing banned, toxic pesticide chlordecone (Kepone), which was used in banana production. For years, an unknown pollution source continuously contaminated water surrounding islands in the French West Indies (Martinique and Guadeloupe). However, researchers from the University of Savoie Mont Blanc in France have found that chlordecone—extensively used on banana farms from 1972 to 1993—is the contamination culprit. Glyphosate is the most popular herbicide in the world, thus ubiquitous in the environment. Therefore, it is vital to understand the implication glyphosate use has on soil health and the potential re-release of soil-bound, toxic contaminants into the surrounding environment to safeguard human health. Researchers note, “[Chlordecone] fluxes drastically increased when glyphosate use began, leading to widespread ecosystem contamination. As glyphosate is used globally, ecotoxicological risk management strategies should consider how its application affects persistent pesticide storage in soils, transfer dynamics, and widespread contamination.” Conventional pesticide use contaminates soil and their respective Critical Zone (CZ) compartments. These CZ compartments interact between the four main spheres (i.e., hydrosphere, biosphere, lithosphere, and atmosphere) of the Earth to support life. Recent decades demonstrate an increase in soil erosion due to sediment changes […]

New Mexico Bill Will Protect Children from Toxic Pesticides Where They Learn and Play

(Santa Fe, New Mexico, February 11, 2021)—New Mexico State Senator Brenda McKenna  introduced the Public Schools Pesticide Management Act (PSPMA) (SB 326) in order to protect school children from exposure to toxic pesticides where they learn and play. The legislation advances ecological pest management, an environmentally healthy way to protect children and the public from weeds and pests, within all schools, classrooms, community parks, and playgrounds in the state. Under PSPMA, only organic and minimum risk pesticides, the least toxic, yet still-effective products on the market will be allowed. Toxic pesticide use will be permitted only under a defined public health emergency, as determined by a public health official. The law does not address the use of pesticides in farming or agriculture.  “All children in New Mexico have the right to a safe environment where they learn and play,” said State Senator Brenda McKenna. “This legislation embraces an environmentally healthy approach to pest management, so families do not have to worry about the use of toxic pesticides in schools and communities.” Pesticide exposure presents unique dangers to children’s health. Children’s developing organ systems are less able to detoxify harmful chemicals, and they often come into closer contact with pesticides than adults in […]

Aggressive Cancer in Sea Lions Linked to Ocean Pollution and Herpesvirus Precursor, Implications for Human Health

(Beyond Pesticides, February 11, 2021) California sea lions (Zalophus californianus) are experiencing high rates of urogenital carcinoma (UGC) cancer incidences from the combined effect of toxic “legacy” pesticides like DDT and the viral infection Otarine herpesvirus-1 (OtHV1), according to a new study published in Frontiers in Marine Science. Previous research documents the role herpesvirus infection, genotype, and organochlorine pesticides play in sea lion cancer development. However, synergism (collaboration) between viral infection and toxic chemical exposure increases cancer development odds. Pollution of the oceans with toxic chemicals lacks adequate regulation, is widespread and only getting worse. More than 80 percent of ocean pollution comes from land-based, anthropological activities. A recent study published in Annals of Public Health finds toxic chemicals from pesticides, heavy metals, plastics, and other sources readily contaminate the ocean, especially near coastal regions where chemical inputs occur in higher concentrations. Globally, pollution has major disease implications, causing the deaths of over nine million people annually. Therefore, it is essential to understand the co-effects of ocean pollution and diseases to protect human health. Authors of the study state, “This study has implications for human health, as virally associated cancer occurs in humans, and likelihood of cancer development could similarly be increased by exposure to environmental […]

Long-Term Roundup Exposure Found to Harm Keystone Wildlife Species

(Beyond Pesticides, January 6, 2021) Long-term exposure to formulated Roundup and glyphosate results in significant harm to wildlife species that form the bottom of aquatic food chains, according to a study published in Microbiome by researchers at University of Birmingham, UK. The water flea Daphnia spp. often functions as a keystone species in lakes and ponds, and because of its ecological importance is frequently used as an indicator species in toxicity tests performed by pesticide regulators. Lead author Luisa Orsini, PhD, notes that most of this testing is flawed by limitations in its scope. “The problem is that much of the evidence is rooted in outdated toxicity tests which only look at the number of animals that die on exposure to extremely high concentrations of these chemicals,” Dr. Orsini said. “These tests also overlook the pathological effects arising from long-term exposure to low doses. What we’re proposing is that toxicity is measured by looking at what happens to the animal at a molecular and fitness level following long-term exposure, which encompasses the entire animal life cycle.” Dr. Orsini and her research team exposed populations of Daphnia magna to the maximum contaminant level (1 mg/L) of both the formulated product Roundup, […]

Act by Sept. 3—Help Keep Toxic Herbicides Out of Lake Tahoe, Protect this Treasured and Sacred Ecosystem; Advance Alternatives 

(Beyond Pesticides, August 31, 2020) We don’t need to use toxic weed killers to manage unwanted vegetation in Lake Tahoe, given the havoc they will wreak on a treasured and sacred ecosystem. The Tahoe Regional Planning Agency and Lahontan Regional Water Quality Control Board (TRPA/LRWQCB) are accepting comments on a draft environmental impact report/ environmental impact statement (EIR/EIS) analyzing environmental impacts of a proposed Tahoe Keys Lagoons Aquatic Weed Control Methods Test (“Project”). Unless we all speak up, the Project could involve the application of herbicides to Lake Tahoe. The Action Alternative 1: Testing of Non-Herbicidal Methods Only is the environmentally best choice and should be selected for the proposed weed control test program. Protect Lake Tahoe from toxic weed killers—take action by Sept. 3, 11:59 pm. Located on the border of California and Nevada, Lake Tahoe is treasured for its scenic and ecological values not just by residents of those states, but by many others. The Washoe Tribe considers the lake to be a sacred life-sustaining water, the center of the world. The lake is designated an “Outstanding National Resource Water” under the Clean Water Act, and is recognized nationally and globally as a natural resource of special significance.  The […]
