Scientists have long blamed environmental estrogens in wastewater for feminizing male fish downstream of sewage plants. Instead of estrogens, however, a new study of treated wastewater identifies a wide range of antiandrogens--compounds that block male hormones--that can accumulate in fish (Environ. Sci. Technol., DOI: 10.1021/es202966c).

“About 90% of the studies on endocrine disruption focus on environmental estrogens,” says Helmut Segner, a toxicologist at the University of . . .
