The metalloid selenium (Se) has the diverse reactivity characteristic of the chalcogens in addition to organometallic behavior. Laboratory measurements indicate that Se is an acute reproductive toxicant, which makes it a concern for the environment. Yet to date, a lack of understanding on how Se species distribute through food webs—bioaccumulation not seeming to conform to dissolved concentrations—has made for very heterogeneous regulation across jurisdictions. In this Feature, Luoma and Presser review Se’s idiosyncrasies to provide an outlook for more realistic ecotoxicologically based regulation.
