Table 4 Bioactivities of polar and non-polar extracts. Colour-coded heatmap summarizing the lowest observed effect concentration (LOEC) and no observed effect concentration (NOEC) of polar and non-polar FCA extracts activities for the majority of bioactive assays

From: Hazardous chemicals in non-polar extracts from paper and cardboard food packaging: an effect-based evaluation

  1. -: denotes samples that were not included in the assay
  2. N/A: ‘not applicable’, meaning that these samples had precipitation problems and were therefore excluded from being tested in the study
  3. *: denotes that the sample was cytotoxic, but bioactive, and was thus not included in the total sum of bioactive sample/assay. Interpret with caution
