| 摘要 |
It is described a method to determine the toxicity caused by exposure to chemical and physical agents consisting in exposing some biological material to said agents and in measuring with an oxygen electrode the O2 concentration change which is due to the respiratory activity of said material, after having added a convenient substratum to the solution with which the material is in contact, said method being characterised in that the biological material used is such that, at the maximum speed of its metabolism, the residual concentration of O2 is higher than zero. |
