||An assay based on the lysosomal incorporation of neutral red dye by brown cells of Mercenaria mercenaria (Bivalvia) was used to measure the cytotoxicity of Cd(sup 2+), Cu(sup 2+), and Ni(sup 2+) singly and in combination. Cytotoxicity was a linear function of Cd(sup 2+) concentration 0.1-1.5 mM and Cu(sup 2+) concentration between 10 and 100 microM. Nickel was not cytotoxic at concentrations as high as 10 mM. The presence of Cu(sup 2+) lessened the cytotoxic effect of Cd(sup 2+). Ni(sup 2+) did not affect cytotoxicity in combination with either Cu(sup 2+) or Cd(sup 2+). Ni(sup 2+) inflated estimates of cell survival by the neutral red assay in this study. Cells exposed to Ni(sup 2+) yielded measured quantities of neutral red dye in excess of those measured in cells from control treatments. (Copyright (c) 1992 Academic Press, Inc.)
