Acute Toxic Class Methods: Alternatives to LD/LC50 Tests.

ALTEX
The Acute Toxic Class (ATC) Methods for the oral, dermal and inhalation routes were developed as alternatives to the respective LD/LC50 Tests. The ATC Methods use at least 40% (and up to 90%) fewer animals and their reliability with respect to classification probabilities into one of several toxicity classes is in the same order of magnitude or even ...
