Results and discussion

Any other information on results incl. tables

With both techniques no growth of microorganisms (isolated organisms: Penecillium pinophilum, Penicillium variabile, Aspergillus ustus, and Aspergillus niger) was observed within three months. Based on this result it can be assumed the substance is not biodegradable in soil.
