摘要：An attempt was made to establish a concentration--time relationship for continuous and interrupted inhalation of a number of nonelectrolytes to establish norms for the permissible content of harmful substances in atmospheric air. The tests showed that the indicated relationship can be expressed in the form of a straight line on a logarithmic grid by using either acute toxicity parameters or the onset of physiological and biochemical shifts. This makes it possible to predict the chronic effect thresholds of substances on the basis of the results of short-term experiments.
