Heterocyclic aromatic compounds containing sulfur (S-HET), have been detected in air, soil, marine environment and freshwater sediment. Toxicity and mutagenicity data of this class of substances are scarce. The present study focuses on implications of two aryl thiophenes and their mutagenic properties in Salmonella/microsome test. In our experiment only 2,4-diphenylthiophene showed little mutagenic effect in both variants of activaction (+/-S9) in strain TA100. Thiophene ring joined to K-region of phenanthrene did not change the biological activity of 3,6-dimetoxyphenanthro [9,10-c]thiophene and this compound did not show mutagenic potency.
