Beryllium toxicity to human, monkey and dog cells in culture.

The toxicity of beryllium was evaluated using a mammalian cell culture system. As the ID50 (a fifty per cent inhibitory dose, to growth of cells after 72 h of incubation) values for HEL-R66, KB, Vero and MDCK cells to beryllium were 0.8 X 10(-3) mM, 1 X 10(-3) mM, 0.9 X 10(-3) mM and 1.2 X 10(-3) mM, respectively, there was no remarkable difference in the sensitivity for these cells to beryllium.
