June 23, 2021 | Small streams are prone to excessively high levels of pesticide contamination that are even more hazardous than once thought, according to a pilot study by a team of German researchers and published in Water Research. The results indicate significant risks for the health of aquatic ecosystems and should be used as […]

Hazardous Pesticide Breakdown Chemicals Found in Streams Nationwide, Raising Health Concerns
March 31, 2021 | Pesticide breakdown products are just as ubiquitous as their parent compounds in urban streams throughout the U.S., according to research conducted by the U.S. Geological Survey (USGS) and published in Environmental Science and Technology. The first of its kind findings place an important spotlight on the long-term impacts of pesticide use […]
Herbicide Use in “Regenerative” No-Till Contaminates Waterbodies
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 […]

Pesticides are polluting our waters — and we often don’t know it
By Puneet Kollipara April 13 Pesticides bring major benefits to modern agriculture, keeping dangerous bugs and fungi and pathogens at bay while boosting yields and making farming more efficient. But what about risks? Like any chemicals — manmade or not — pesticides can be bad for human health and ecosystems if they’re toxic enough […]

Honeybees and Groundwater: Canaries in the Pesticide Coalmine
Maryland’s Pesticide Reporting and Information workgroup heard from a new voice about the need for a centralized reporting system for basic information — information that is already legally required — on when and where pesticides are used commercially in our state. In his testimony to the workgroup, President of the Central Maryland Beekeepers Roger Williams […]

EPA Publishes Human Health Benchmarks for Pesticides in Water
(Beyond Pesticides, April 18, 2012) In the face of widespread pesticide contamination of U.S. waterways and the lack of drinking water standards for hundreds of pesticides, the U.S. Environmental Protection Agency (EPA) has announced new health and environmental benchmarks for acute pesticide effects, postponing action on chronic effects to an unspecified future date. While a […]

Sexual Disruption Linked to Environmental Pollutants
(Beyond Pesticides, January 22, 2009) A new English study has found that chemicals found in rivers and waste waters could be linked to male infertility. These chemicals, known as anti-androgens, block the action of the male sex-hormone testosterone and could impact the development of male reproductive organs in humans. The study entitled, “Statistical Modeling Suggests […]
