No specific relationship could be established between complaints and chemicals used in the brands of carbonless copy paper on the Swedish market. The symptoms were non-specific and very variable. Any office encountering these problems must have them analyzed separately to find the local explanation. Carbonless copy paper has been in widespread use for more than 20 years. Although several reports have been published about suspected health hazards from such papers, none has been able to prove any relationship between carbonless copy papers in general and health hazards (see bibliography). That all chemicals in a product are absolutely safe can never be proved, but if all efforts to prove them dangerous fail, the suspicions of their hazards must diminish. Investigations must concentrate on finding the local cause of the trouble.
在瑞典市场上，无碳复写纸品牌中使用的化学物质与投诉之间无法建立特定关系。症状不具有特异性且变化很大。任何遇到这些问题的办公室都必须单独对其进行分析，以找到当地的原因。无碳复写纸已经广泛使用了20多年。尽管已经发表了几篇关于此类纸张疑似健康危害的报告，但没有一篇能够证明一般的无碳复写纸与健康危害之间存在任何关系（见参考文献）。产品中的所有化学物质绝对安全是永远无法证明的，但如果所有证明它们危险的努力都失败了，对其危害的怀疑就一定会减少。调查必须集中在找出问题的当地原因上。
