A team of U.S. Geological Survey (USGS) scientists recently reported on field results in the journal Environmental Toxicology and Chemistry. Two fungicides, pyraclostrobin and tebuconazole, and the herbicide simazine were detected frequently in amphibians from all sites sampled. The USGS study is the first to document the occurrence of these fungicides in amphibians and one of the first studies to measure fungicides in tissue." }, { "@type": "TextObject", "text": "This study was funded by the USGS Toxic Substances Hydrology Program, Amphibian Research and Monitoring Initiative, and Wildlife: Terrestrial and Endangered Resources Program." }, { "@type": "TextObject", "text": "Frog populations are declining worldwide and pesticides are thought to be one of the contributing causes, acting singly or in combination with other stressors. Not much is known about the exposure of frogs to pesticides, especially in remote areas (areas away from where pesticides are applied). The scientists looked at pesticides in Pacific Chorus frogs (Pseudacris regilla) and their habitat (water and sediment) in seven remote, high-elevation locations in California (including Giant Sequoia National Monument, Yosemite National Park, and Lassen Volcanic National Park). Chorus frogs were studied because they are found in a broad geographic area, they are still relatively abundant, and USGS scientists have been investigating their decline for over a decade. Fungicides (pesticides used to control fungal diseases) were found in adult male frogs from all sites. The sites sampled were downwind of California\u2019s Central Valley; a potential cause of exposure may be from pesticides transported to these locations via precipitation and dust. Data generated from this study indicate that amphibians residing in these remote locations are exposed to and capable of taking up current-use pesticides." } ], "funder": { "@type": "Organization", "name": "Environmental Health Program", "url": "https://www.usgs.gov/programs/environmental-health-program" }, "about": [ { "@type": "Thing", "name": "Environmental Health Featured Science Activities" }, { "@type": "Thing", "name": "Water" }, { "@type": "Thing", "name": "Information Systems" }, { "@type": "Thing", "name": "fungicides" }, { "@type": "Thing", "name": "Aquatic Ecology" }, { "@type": "Thing", "name": "california" }, { "@type": "Thing", "name": "Methods and Analysis" }, { "@type": "Thing", "name": "Aquatic Ecosystems" }, { "@type": "Thing", "name": "Geology" }, { "@type": "Thing", "name": "Energy" }, { "@type": "Thing", "name": "Environmental Health" }, { "@type": "Thing", "name": "pesticides" }, { "@type": "Thing", "name": "Science Technology" }, { "@type": "Thing", "name": "Pesticides and Pesticide Degradates" }, { "@type": "Thing", "name": "Species Management Research Program" }, { "@type": "Thing", "name": "Climate" }, { "@type": "Thing", "name": "Herbicides" }, { "@type": "Thing", "name": "Pesticides" }, { "@type": "Thing", "name": "Environmental Stressors" }, { "@type": "Thing", "name": "Environmental Toxicology" }, { "@type": "Thing", "name": "Amphibians/ARMI" } ]
