测量了三个燃木壁炉的颗粒物和气体排放量。每公斤燃烧的木材平均排放 10 克颗粒。该颗粒是球形的，质量中值直径为约0.17μm。尽管该材料是碳质的，但有机碳/元素碳的分解似乎取决于木材类型和燃烧的原木的大小。报告了苯并[a]-芘排放量以及颗粒物的艾姆斯测试结果。气体连续测量表明平均排放量为 110 g/kg CO、1.5 g/kg HC 和 0.7 g/kg NO*。这里测量的排放值与其他测量值结合使用来估计丹佛冬季木材燃烧的重要性。根据三种估算技术，木材燃烧占丹佛冬季细颗粒物的 20-30%。
Particulate and gaseous emissions were measured from three wood-burning fireplaces. An average of 10 g of particles/kg of wood burned was emitted. The particles were spherical with a mass median diameter of about 0.17 fim. Although the material is carbonaceous, the organic carbon/elemental carbon split seems to depend on both the wood type and the size of the log burned. Benzo [a]-pyrene emissions as well as Ames tests results on the particulate are reported. Continuous measurements of gases indicated average emissions of 110 g/kg CO, 1.5 g/kg HC, and 0.7 g/kg NO*. The emission values measured here were used in conjunction with other measurements to estimate the importance of wood burning in wintertime Denver. Based on three estimating techniques, wood burning accounts for 20-30% of the Denver wintertime fine particulate.
