The toxicological effects of waste‐to‐energy ash‐concrete on survivorship, growth, and fecundity (end‐point parameters) of Mysidopsis bahia and on survivorship and growth of Menidia beryllina were evaluated with the 7‐d static‐renewal toxicity test. Leachate (10‐, 5‐, and 1‐d) and elutriate (100, 50, 25, 12.5, and 6.25%) solutions were prepared from experimental ash‐concrete test cylinders constructed from concrete with additions of either bottom ash (mix BA), mixed bottom ash and scrubber residue (70:30%; mix BA:SR), or mixed bottom ash and fly ash (60:40%, mix BA:FA). Control experiments with concrete (without ash) and pH (7‐9.5) were conducted to assess any toxic effects of the stabilization process. pH did not affect end‐point parameters of Mysidopsis bahia or Menidia beryllina . However, the 100% elutriate solution made from concrete reduced survivorship of Mysidopsis bahia . For experiments with ash‐concrete test cylinders with the BA mixture, 10‐d leachate solution reduced survivorship of Mysidopsis bahia and the 100% elutriate solutions reduced survivorship of Mysidopsis bahia and Menidia beryllina . With the BA:SR mixture, the 100 and 50% elutriate solutions reduced survivorship of Mysidopsis bahia , and the 10‐d leachate solution reduced survivorship of Menidia beryllina . The BA:FA 10‐ and 5‐d leachate solutions and the 100, 50, and 25% elutriate solutions reduced survivorship of Mysidopsis bahia.
