‘Scientists found intersex fish in three river basins in Pennsylvania, a sign that the water may be tainted with chemicals from human activity.
Male smallmouth bass with female characteristics — namely, immature egg cells in their testes — were discovered in the drainage areas of the Susquehanna, Delaware and Ohio rivers, according to a new study led by the U.S. Geological Survey (USGS).
Such abnormalities are linked to estrogen-mimicking chemicals, which likely got into rivers and streams from agricultural runoff and human waste, the researchers said.’
