Results and discussion

Any other information on results incl. tables

Remark: Vanillin was identified in effluents sampled at different steps of a  full-scale bleaching plant, using silver birch as pulpe source.
RS-Freetext:
Vanillin concentrations are expressed as mg of vanillin per g of dry  sample amount analysed by PY-GC-MS. For bleaching stage signification to
