This attempt to synthesize the present state of knowledge on the correlation between the structure of chosen PAHs and their mutagenic or carcinogenic activity shows that the dependencies cannot be treated univocally. Extreme complexity of the subject, typical for investigations on the boundary between chemistry and biology, inclines one to search for new ways of synthesis of new compounds, which would be of interest for biologists studying the problem of chemical carcinogenesis. On the other hand, there is a strong need for elaborating a standardized test that would explicitly define the carcinogenic properties of a specific compound. The use of a variety of methods for the determination of carcinogenic potency of chemical compounds combined with simultaneous differentiation of structure of examined compounds, sometimes leads to contradictory conclusions. Correlation between mutagenic and carcinogenic activity of some compounds is also sometimes questionable. Modern molecular biology should allow for elaborating a method which would give a satisfactory and reliable answer to the fundamental question: is a specific compound carcinogenous for a human organism? And if so - to what extent?
