Male fish with signs of feminization, including the development of eggs, have been discovered in Pennsylvania’s Delaware, Ohio, and Susquehanna river basins. The find is a sign of hormone-disrupting chemicals in the water, possibly from mixtures of pesticides, pharmaceuticals, and personal care products, like cosmetics and antibacterial soaps, seeping into the rivers, Philly.com reports. The state’s Department of Environmental Protection has begun sampling river systems to learn which exact compounds are present, and if they could possibly affect humans.
