%X It is evidenced by the filter elution method that two carcinogenic aromatic hydrocarbons, benzoa]pyrene and dibenzoa,h]anthracene, two carcinogenic metal salts, beryllium chloride and cadmium chloride, four carcinogenic aromatic amines, 2-aminofluorene, β-naphthylamine, 4-aminobiphenyl and benzidine, can all induce DNA interStrand and DNA-protein cross-link in L1210 culture. However, under the same condition, the corresponding non-carcinogenic compounds, including benzok]fluorancene, anthracene, magnesium chloride, zinc chloride, α-naphthylamine, 2-aminobiphenyl andm-toluidine, cannot produce any cross-link adducts. All these results are consistent with the di-region theory that carcinogens are bio-bifunctional alkylation agents. This method can also be used to discriminate carcinogens and non-carcinogens.
