Selenium: an insidious and persistent toxin
..., "because the primary impact is on the egg, which receives the toxin from the mother's diet. When the eggs are hatched, the developing fish metabolize the selenium. Some fish are visibly deformed, but others grow into adult fish that appear healthy yet fail to reproduce. Because there is no apparent fish kil...May media highlights: GEOLOGY and GSA TODAY
