Pesticides from California’s valley farms are collecting in the tissues of a singing treefrog that lives in pristine national parks, including Yosemite and Giant Sequoia, a new study finds.
The chemicals include two fungicides never before found in wild frogs, said Kelly Smalling, lead study author and a U.S. Geological Survey (USGS) research hydrologist. The study was published today (July 26) in the journal Environmental Toxicology and Chemistry.
“Fungicides have been registered for use for many years, but for some reason, they haven’t really been on anybody’s radar screen until recently,” said Smalling, who is based at the USGS California Water Sciences Center in Sacramento.
