Extracts of typewriter ribbons and carbon papers were found to be mutagenic in the Salmonella/microsome assay with strain TA98. Fractionation of ribbon extracts indicates that at least 2-3 different classes of mutagenic component are present in these extracts. Nitro-containing compounds may be responsible for the high mutagenicity observed for some of the ribbon extracts in the absence of S9. The results indicate that impurities in the products may be causing part of the mutagenic effect.
打字机色带和复写纸的提取物在使用TA98菌株的沙门氏菌/微粒体试验中被发现具有致突变性。色带提取物的分级分离表明，这些提取物中至少存在2 - 3种不同类别的致突变成分。含氮化合物可能是某些色带提取物在无S9时观察到的高致突变性的原因。结果表明，产品中的杂质可能是致突变效应的部分原因。
