Abstract

Aromatic hydrocarbons in the range of 1–4 nuclear rings were examined for mutagenicity in the so-called “taped-plate assay”. This modification of the Ames assay is particularly equipped for the detection of volatile mutagens. Of the many compounds tested only phenanthrene, pyrene, benzo[ c]phenanthrene and benzoacenaphthylene were positive in this assay. The present data underline the exceptional behaviour of fluoranthene by being a rather potent bacterial mutagen with a volatile nature (as found in a previous study).
