title: Dose-response relationship for chromosome aberrations induced by fecapentaene-12 in human lymphocytes.
abstract: Chromosome analyses were carried out in human lymphocytes exposed to a synthetic racemic all-trans fecapentaene-12 at 2-24 microM. A dose-dependent increase of the incidences of chromatid-type changes with distinct saturation at higher doses could be observed. The results reveal for the first time that fec-12 is a potent direct-acting mutagen in human lymphocytes.
