title: Mutagenic activity in photocopies.
abstract: Extracts from several different photocopies were mutagenic in the Ames Salmonella assay. The mutagenic behavior was similar for extracts from copies and corresponding toners indicating that toners are directly responsible for the mutagenicity. The mutagenicity is caused by at least two classes of compounds which may be present either alone or in combination in any toner.
