title: The detection of various nitrosamines in the hepatocyte primary culture/DNA repair test.
abstract: Evaluation of 6 carcinogenic nitrosamines in the hepatocyte primary culture/DNA repair test revealed that all were active. Three non-carcinogenic analogs were negative. This sensitivity to nitrosamines, together with considerations concerning the metabolic capability and end point of this assay, indicates that it will be a useful addition to screening batteries that include bacterial mutagenesis assays.
