Cell viability (A) and colony survival (B) was evaluated after treatment with and without cadmium in RSa cells (□) and UVr-1 cells (Ο). Cells were treated with and without cadmium and viability and colony survival were estimated as described in Materials and Methods. The data represents the average percentage of numbers relative to those of mock-treated cells, and are the means ± S. E. M. of three independent experiments.
