Many of the substances identified are methoxyphenols (derivatives of syringol and guaiacol), polycyclic aromatic hydrocarbons (PAH), oxidized PAH (oxy-PAH), and levoglucosan, the last being a monosoccharide derivative from the thermal breakdown of cellulose. The amount of unsubstituted PAH was greater than that of methyl- and dimethyl-substituted homologs.475-481enggas chromatography-mass spectrometrypolycyclic aromatic hydrocarbonswood burningcharcoalretention indicesArtigo10.1007/BF02492280WOS:000175277600016Acesso restrito
