Test with algae (H. pluvialis)—Inhibition/stimulation of all eluates of samples in comparison with the aquatic control. The data are expressed as the inhibition of the specific growth rate of algal biomass. A total of 3 replicates were used for all samples including control. FF = Flax Fibers, FF + E = Flax Fibers treated by Epoxy resin, FF + E + C 1% = Flax Fibers treated by Epoxy resin and a Caffeine solution of 10 g/L, FF + E + C 2% = Flax Fibers treated by Epoxy resin and Caffeine solution of 20 g/L. The asterisks express the statistical significance in comparison to the control medium, Dunnett’s post hoc test at the α level of 0.05).
