Exposure of hamster embryo cells (HEC) to mixtures of benzo( a ) pyrene and soluble Ni 2+ neutral salts elicits additive responses in the enhanced nucleoside excretion assay. Ni 2+ shows no significant excretion response until concentrations near 10 μM are reached. Addition of 0.4 micromolar benzo( a )pyrene and 30 μM, or 325 μM Ni 2+ to HEC cultures results in total excretion equal to the sum of excretions induced by the individual chemicals. These observations suggest that excretion of pyrimidines may be a useful measure of biological dosimetry.
