Distribution Behavior of Mutagenic Compounds Formed During Carbonization Process of Wood

The distribution behavior of mutagenic compounds formed during carbonization process of cypress wood was investigated by examining the mutagenicity of the carbonized woods, and gaseous and tar-like compounds (by-products) from the wood carbonization. The examination results showed that the mutagenic compounds were mainly transferred into the gas phase, and so these compounds are expected to be direct-acting mutagens causing base-pair substitution. To produce carbonized wood for recycling waste wood, a gas collector for removal of the gaseous compounds from the carbonization is required, and also must be followed by the suitable treatment of the collected mutagenic compounds.
