Beschreibung
Zusammenfassung:	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. L'invention porte sur un procédé déterminant la toxicité résultant d'une exposition à des agents chimiques et physiques consistant à exposer un matériau biologique donné auxdits agents et à mesurer à l'aide d'une électrode d'oxygène les variations de la concentration en O2 dues à l'activité respiratoire dudit matériau, et cela après avoir ajouté à la solution un substrat convenable avec lequel le matériau est en contact. Ledit procédé se caractérise en ce que le matériau biologique utilisé est tel qu'à sa vitesse maximale de métabolisme la concentration résiduelle d'O2 soit supérieure à zéro.
