Federal scientists may have found a link between the 1989 Exxon Valdez oil spill and a decline of herring and pink salmon populations in Prince William Sound. In a study published Tuesday in the online journal Scientific Reports, researchers from the National Oceanic and Atmospheric Administration (NOAA) found that embryonic salmon and herring exposed to even very low levels of crude oil can develop heart defects. Herring and pink salmon juveniles that were exposed to crude oil as embryos grew slower and swam slower, making them vulnerable to predators, said John Incardona, a research toxicologist at NOAA Fisheries’ Northwest Fisheries Science Center in Seattle, in a prepared statement Exxon Valdez: 25 years later We explore the lasting impacts of oil spills on communities and the country. “These juvenile fish on the outside look completely normal, but their hearts are not functioning properly and that translates directly into reduced swimming […]
