[Principles of formalizing a quantitative evaluation of the genetic danger of chemical compounds for man].

Specific characteristics of the mutagenic effect of chemicals, which must be taken into account in developing the test system to assess the potential genetic risk caused by chemical substances, are considered. The organizational principles of the procedures currently available for testing and ranking chemicals by their mutagenic and carcinogenic hazard to humans are discussed. The use of selective information suggested by Wiener and Shannon as an efficiency measure of testing and estimating the potential genetic hazard of chemical substances is substantiated. The feasibility of this approach was demonstrated by testing the efficiency of the battery of two short-term in vitro tests as an example. It was shown that selective information is able to serve as an integral universal criterion of the efficiency of testing, if either one test or the test battery were used.
