摘要：

Smoke particles from wood burning and duff burning were analysed for polycyclic aromatic hydrocarbons (PAH) by gas chromatography/mass spectrometry. PAH composition in smoke particles from wood burning was found to resemble those from other environmental samples, such as air particles and sediments where parental PAH are the predominant species. A catalytic combustor retrofitted on the wood-burning stove reduced the PAH concentrations significantly. The reduction was more pronounced for parental PAH than their alkylated homologs. Probably, the molecular configuration affects the catalytic efficiency. Smoke particles from duff burning contained a strikingly different PAH composition, with phenanthrene, alkylated phenanthrenes, alkylated cycolopenta(def)phenanthrene and dodecahydrochrysene as the predominant species.
