On April 20, the National Marine Fisheries Service (NMFS) released a Biological Opinion (BiOp) finding that three additional pesticides, carbaryl, carbofuran, and methomyl, harm salmon and steelhead protected under the Endangered Species Act (ESA). The BiOp prescribes measures necessary to keep these pesticides out of salmon waters in Washington, Oregon, California, and Idaho. It is […]

(Beyond Pesticides, October 6, 2008) University of Pittsburgh researchers have found that the commonly used insecticide malathion can decimate tadpole populations by altering their food chain. The study, published in the October 1 edition of Ecological Applications, finds that gradual amounts of malathion that were too small to directly kill developing leopard frog tadpoles instead […]

(Beyond Pesticides, July 17, 2008) In a new study published in Environmental Health Perspectives, researchers have found an increased occurrence of intersex toads in areas with greater agricultural land cover. This points to a link between certain pesticides and endocrine disruption, a change in the hormonal balance that can have sexual and reproductive effects. Such […]

(Beyond Pesticides, April 10, 2008) Common frogs that live in suburban areas are more likely than their rural counterparts to develop reproductive abnormalities, according to David Skelly, PhD, professor of ecology at the Yale School of Forestry and Environmental Studies. This phenomenon becomes a serious concern as the frog’s mating season begins, leaving researchers to […]

(Beyond Pesticides, March 24, 2008) Scientists at the U.S. Geological Survey (USGS) announced that they have identified ten contaminants, including pesticides, in the Potomac River, which flows through downtown Washington, DC, that could be responsible for the alarming discovery of “intersex fish,” male fish producing eggs. The suspected chemicals include: atrazine, a common herbicide used […]

(Beyond Pesticides, February 20, 2008) Pesticides that run off agricultural land and mix in rivers and streams combine to have a greater than expected toxic effect on the salmon nervous system, according to researcher Nathaniel Scholz, PhD, a zoologist with the National Oceanic and Atmospheric Administration (NOAA) in Seattle. Dr. Scholz, who presented his findings […]
