Ecosystem Health: Pesticide Use from Forest Management Practices Threatens Essential West Coast Marine Organisms

Posted on

March 11, 2021 | A Portland State University (PSU) study, published in Toxics, finds that pesticides from the forestry industry threaten clams, mussels, and oysters (bivalves) along the Oregon state coast. Bivalves are excellent indicator species, signaling environmental contamination through their sedimentary, filter-feeding diet. However, continuous pesticide inputs— from various forestry management regimes—into watersheds along […]

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

Posted on

March 4, 2021 | A study in Environmental Science and Technology finds that glyphosate use stimulates soil erosion responsible for releasing the banned, toxic pesticide chlordecone (Kepone), which was used in banana production in the French West Indies (Martinique and Guadeloupe). For years, an unknown pollution source continuously contaminated water surrounding the islands. However, researchers […]

Solitary Wild Bees Harmed by Neonicotinoid Pesticides Applied by Soil Drenching

Posted on

March 2, 2021 | Populations of solitary ground nesting bees decline after exposure to neonicotinoid insecticides, according to a study in Scientific Reports. In addition to ground nesting bees, neonicotinoids have been shown to harm butterflies, hummingbirds, songbirds, aquatic species and mammals, including humans. As independent science continues to look beyond the effects of these […]

Glyphosate and Other Weed Killers Create Antibiotic Resistant Bacteria in Agricultural Soils

Posted on

February 24, 2021 | Soil sprayed with weed killers glyphosate, glufosinate, or dicamba are likely to contain higher amounts of antibiotic resistant bacteria, according to research published in Molecular Biology and Evolution. Each year in the U.S., at least two million people develop an antibiotic resistant infection and over 23,000 die. Authors of the study […]

Hummingbirds Harmed by Pesticides Killing Off Bees, Butterflies, and Other Pollinators

Posted on

February 23, 2021 | The same pesticides implicated in the worldwide decline of insect pollinators also present significant risks to their avian counterparts, hummingbirds. Well-known for their nectar-fueled hovering flight powered by wings beating over 50 times per second, hummingbirds display unique reactions to toxic pesticides. Researchers at the University of Toronto published in Scientific […]

Herbicide Use in “Regenerative” No-Till Contaminates Waterbodies

Posted on

February 19, 2021 | Vermont Public Radio (VPR) reports on revelations from a retired state scientist, Nat Shambaugh, who finds that farmers’ efforts to reduce agricultural runoff from fields into water bodies, by planting cover crops, has resulted in significant increases in the use of herbicides to kill off those crops. So as one kind […]

Monarch Butterfly Near Extinction—Calls for Urgent Federal Action

Posted on

January 27, 2021 | Lowest ever recorded! That’s the result of a yearly winter monarch count along the California coast, overseen each year by the conservation group Xerces Society. In 2020, citizen scientists counted only 2,000 butterflies. The findings indicate that many on the planet today are likely to experience, within their lifetimes, a world […]

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

Posted on

January 11, 2021 | California sea lions (Zalophus californianus) are experiencing high rates of urogenital carcinoma (UGC) cancer incidence from the combined effect of toxic “legacy” pesticides like DDT and the viral infection Otarine herpesvirus-1 (OtHV1), according to a study in Frontiers in Marine Science. Previous research documents the role herpesvirus infection, genotype, and organochlorine […]
