University of Pittsburgh researchers have found high levels of mercury and estrogen in the fish caught in our three rivers. The research team also found fish that had neither male nor female reproductive organs. Since 2008, the river has filled each summer with levels of contaminants higher than in at least 10 years. Researchers think the chemicals are accumulating in the fish because “vast quantities” of human waste containing pharmaceutical byproducts are running into local rivers from untreated sewage. Many people have gotten into the habit of flushing waste pharmaceuticals down the toilet because it is convenient, low cost, and prevents unintended use or other diversion. There are better options.
