Description

Genotoxicity related to aminoarenes and nitroarenes was evaluated with matters produced during incineration, which would be induced by charred proteins and/or petroleum. We investigated the genotoxicity on discharge water from sludge incineration stokers in a sewage treatment plant using the activated sludge treatment method, fly ash and bottom ash of incineration plants of domestic waste and leachate by using the umu-test which can detect with high sensitivity genotoxicity with aminoarenes and nitroarenes.<BR>Strong genotoxicity could be detected in the fly ash related to aminoarenes and the step grate stoker furnace incinerating sludge and leachate. These facts show that the incineration processes can induce those materials, amino and/or nitroarenes with genotoxicity.
