Effects of duration of exposure of single metal cations (Ag+1, Cd+2, Cu+2, Ga+3, Ni+2, and Zn+2) on 3H‐thymidine (3H‐Tdr) incorporation and 3‐[4,5‐dimethylthiazol‐2yl‐]‐2,5‐diphenyl tetrazolium bromide‐formazan (MTT‐f) production in cultured murine fibroblasts (Balb/c 3T3) were investigated, and the synergistic and antagonistic effects of two metal cations applied simultaneously to the fibroblasts were assessed. The effects of duration of exposure were quantified using TC50 values (concentration of an element required to cause 50% toxicity compared with controls) measured after 24, 48, or 72 h. Using MTT‐f production, Cd+2, Cu+2, Ga+3, and Ni+2showed significantly lower TC50 values with increasing time of exposure, whereas the TC50 values for Ag+1and Zn+2remained constant. The TC50 values using3H‐Tdr incorporation exhibited a similar pattern with time of exposure, but the effects were less pronounced. The TC50 values for3H‐Tdr and MTT‐f tended to equalize at 72 h. All combinations of cations tested (Ag‐Cu, Ag‐Zn, Ag‐Ni, Cu‐Zn, Cu‐Ni, Cu‐Ni, Ga‐Ni, and Cu‐Cd) exhibited synergistic and antagonistic effects were not necessarily mutually exclusive in the same system. © 1992 John Wiley & Sons, Inc.
