Abstract:A novel phenomenon of degradation of polypropylene plastic by volatile constituents of Ledum palustre is reported in this study. The characteristic of degradation is described by tensile strength, melting point, and scanning electron micrographs as well as optical micrographs. The chemical composition of volatile oil of Ledum palustre is analyzed by gas chrography and mass spectrometry. The mechanism of degradation and problems needed to be solved are also discussed.
