The application of short-term tests to paper and board

5 The application of short-term tests to paper and board 

So far there have been relatively few published reports on the application of in-vitro toxicological tests to extracts of paper and board. The published results relate to the use of photobacterium test, RNA-synthesis inhibition assay or to a battery of different test systems. The outcomes of these trials are summarised below.

In the test applied ethanol extracts showed more toxicity than water extracts and also contained higher amount of material in the chemical analysis. Sample A produced least extractants, and was also least cytotoxic. Among the recycled
