Abstract: March 19, 2013 | As part of a study on impacts from the world’s most widely used class of insecticides, nicotine-like chemicals called neonicotinoids, American Bird Conservancy (ABC) has called for a ban on their use as seed treatments and for the suspension of all applications pending an independent review of the products’ effects […]

Farm pesticides blamed for fish kill
July 10, 2012 – 4:16am By ALY THOMSON The Canadian Press ‘Acute toxic event’ may have led to die-off in brook, biologist says COLEMAN, P.E.I., The discovery of hundreds of dead fish in Prince Edward Island is spawning concerns from environmentalists about the use of pesticides in the province’s agriculture industry. Dale Cameron of Trout […]
Roundup Linked to Animal Shape Changes
(Beyond Pesticides, April 4, 2012) The world’s most popular weed killer can induce morphological changes in vertebrate animals, U.S. biologists studying its effect on amphibians say. University of Pittsburgh researchers have found that the weed killer Roundup, in sub-lethal and environmentally relevant concentrations, causes two species of amphibians to change their shape by interfering with […]
Study Finds Common Fungicide Deadly to Frogs
(Beyond Pesticides, April 14, 2011) Researchers at the University of South Florida have discovered that the most widely used fungicide in the U.S., chlorothalonil, is lethal to frogs even at low doses. Chemical pollution, according to the researchers, is considered the second greatest threat to aquatic and amphibious species in the U.S. Because many vital […]

First Report on Bioaccumulation and Processing of Antibacterial Ingredient TCC in Fish
ScienceDaily (Apr. 1, 2011) In the first report on the uptake and internal processing of triclocarban (TCC) in fish, scientists have reported strong evidence that TCC — an antibacterial ingredient in some soaps and the source of environmental health concerns because of its potential endocrine-disrupting effects — has a “strong” tendency to bioaccumulate in fish. […]
USGS Finds Atrazine Herbicide Adversely Affects Fish Reproduction
(Beyond Pesticides, June 1, 2010) Atrazine, one of the most commonly used herbicides in the world, has been shown to affect reproduction of fish at concentrations below U.S. Environmental Protection Agency’s (EPA) water-quality guideline, according to a new U.S. Geological Survey (USGS) study. “Concentrations of atrazine commonly found in agricultural streams and rivers caused reduced […]

More Research Links Atrazine to Sexual Abnormalities in Amphibians
(Beyond Pesticides, March 3, 2010) A recently published study in the Proceedings of the National Academy of Sciences finds that male frogs exposed to the herbicide atrazine can become so completely female that they can mate and lay viable eggs. This latest study adds to the growing scientific evidence which shows that atrazine, one of […]

Pyrethroid Pesticides in Streams Found Toxic to Indicator Species
(Beyond Pesticides, February 16, 2010) Pyrethroids, among the most widely-used home pesticides, are winding up in California rivers at levels toxic to some stream-dwellers, possibly endangering the food supply of fish and other aquatic animals, according to a study by researchers at the University of California, Berkeley, and Southern Illinois University (SIU). The study, “Urban […]

U.S. Geological Survey Identifies Intersex Fish Nationwide
(Beyond Pesticides, September 18, 2009) Previously documented in the Potomac River, which flows through downtown Washington, DC, the occurrence of “intersex” fish is now found to be nationwide. U.S. Geological Survey (USGS) researchers published their study, “Widespread occurrence of intersex in black basses from U.S. rivers” in the online edition of Aquatic Toxicology. USGS researchers […]

Pesticide Drift from Fields Impact Amphibian Populations
(Beyond Pesticides, July 23, 2009) A new study published in the August 2009 issue of Environmental Toxicology and Chemistry found that insecticides used in highly populated agricultural areas of California’s Central Valley affect amphibians that breed in the Sierra Nevada Mountains to the east. This study adds to the increasing evidence that pesticides impact areas […]
