“…In contrast, their proportions from initial, glowing, and tiled stove burning were much lower. This is consistent with observed extensive formation of P AH from wood above 800°C but not below 600°C [1,10,11]. The proportions of the bicyclic and more volatile naphthalene were large but varied less strikingly.…”

The emissions from a traditional tiled stove consisted mainly of lignin-related methoxyphenols with antioxidant properties, and 1,6-anhydroglucose from cellulose degradation. A wood stove of presently introduced energy-efficient design for residential heating and hot-water supply was shown to emit small amounts of methoxyphenols and anhydrosugars from primary wood pyrolysis. Secondary harmful components like benzene and polycyclic aromatic hydrocarbons constituted a major portion of the organic emissions. It is concluded that differences in smoke composition are essential to consider in recommendations and rules for proper choices of wood burning devices.

“…The ratio between benzene and methylbenzene was several times higher for glowing than for flaming burning, and also higher than for smoke from flaming stove burning of wood [8,10]. The proportions of naphthalene and phenanthrene as indicators of polycyclic aromatic hydrocarbons are much lower, as anticipated at the low combustion temperature [2,10,14].…”

“…1), and naphthalene as well as more hazardous polycyclic aromatic hydrocarbons, were formed in comparatively low proportions. The relative proportions of all these compounds increase with· increasing combustion temperature [2,10,14]. This is balanced by a rapid decrease of the primary degradation products from lignin and polysaccharides, as demonstrated both for controlled pyrolysis [2] and for chimney emissions [10].…”

“…In contrast, carbonylcontaining methoxyphenols were observed to be the most prominent in fine particles from biomass burning [3, l3]. For toxicity testing, semi-volatile compounds from wood burning have been collected on Tenax cartridges with subsequent solvent extraction [14].…”

Semivolatile compounds in smoke from gram-scale incomplete burning of plant materials were assessed by gas chromatography and mass spectrometry. Gas syringe sampling was shown to be adequate by comparison with adsorbent sampling. Methoxyphenols as well as 1,6-anhydroglucose were released in amounts as large as 10 mg/kg of dry biomass at 90 % combustion efficiency.Wood, twigs, bark and needles from the conifers Norway spruce and Scots pine emitted twelve reported 2-methoxyphenols in similar proportions. Grass, heather and birchwood released the same 2-methoxyphenols but also the corresponding 2,6-dimethoxyphenols which are characteristic of angiosperms. The, methoxyphenols are formed from lignin and 4iffer in structure by the group in para position relative to the phenolic OH group. Prominent phenols were those with trans-1-propenyl and ethenyl groups in that position. Vanillin, 4-hydroxy-3-methoxybenzaldehyde, was a prominent carbonyl compound from the conifer materials.
