The presence of the mutagenic polycyclic aromatic hydrocarbons benzo[a]pyrene and benz[a]anthracene in creosote P1.
Several fractions of creosote P1 separated by TLC showed mutagenicity towards Salmonella typhimurium TA98. Thus mutagenicity is probably caused by the presence of mutagenic aromatic hydrocarbons. The mutagenic polycyclic aromatic hydrocarbons, benzo[a]pyrene and benz[a]anthracene, were detected in concentrations of 0.18 and 1.1% respectively. Because these compounds are probably not essential for the wood-preserving properties of creosote , a more selective composition of the product should be considered.
