生物质燃烧已被证明是世界上发展中国家和高收入国家室内空气质量差（IAQ）的主要来源。具体来说，燃烧木材做饭和取暖导致室内细颗粒物（空气动力学直径<2.5 μm的颗粒；PM2.5）和粗颗粒物（空气动力学直径<10 μm和>2.5 μm的颗粒；PMc）浓度很高。内毒素主要存在于空气中颗粒物质的粗颗粒中，在易感人群中与促炎作用和不良后果有关。本研究的目的是评估空气过滤器干预措施在减少室内PM2.5、pmmc和pmmc相关内毒素浓度方面的效果。家庭（n=48）随机接受室内空气过滤装置，其中要么是高效过滤器（即主动），要么是效率较低的玻璃纤维过滤器（即安慰剂）。主动过滤器干预显示，与安慰剂干预相比，室内PM2.5浓度降低了66% （95% CI：降低42.2%至79.7%）。活性过滤器和安慰剂过滤器都有效地大幅降低室内PMc浓度（活性过滤器和安慰剂过滤器分别平均降低63.3%和40.6%）和PMc相关的内毒素浓度（分别平均降低91.8%和80.4%）。这些发现支持使用高效空气过滤装置来减少使用木炉进行一次供暖的家庭的室内PM2.5。我们还发现，使用效率较低、成本较低的过滤器替代品可以有效地减少燃烧生物质燃料的家庭中的PMc和空气中内毒素。
Biomass burning has been shown to be a major source of poor indoor air quality (IAQ) in developing and higher income countries across the world. Specifically, wood burning for cooking and heating contributes to high indoor concentrations of fine (particles with aerodynamic diameters <2.5 μm; PM2.5) and coarse (particles with aerodynamic diameters <10 μm and >2.5 μm; PMc) particulate matter. Endotoxin, predominantly found within the coarse fraction of airborne particulate matter, is associated with proinflammatory effects and adverse outcomes among susceptible populations. The aim of this study was to assess the efficacy of air filter interventions in reducing indoor PM2.5, PMc, and PMc-associated endotoxin concentrations in homes using a wood stove for primary heating. Homes (n=48) were randomized to receive in-room air filtration units with either a high efficiency filter (i.e. active) or a lower efficiency fiberglass filter (i.e., placebo). The active filter intervention showed a 66% reduction in indoor PM2.5 concentrations (95% CI: 42.2% to 79.7% reduction) relative to the placebo intervention. Both the active and the placebo filters were effective in substantially reducing indoor concentrations of PMc (63.3% and 40.6% average reduction for active and placebo filters, respectively) and PMc-associated endotoxin concentrations (91.8% and 80.4% average reductions, respectively). These findings support the use of high efficiency air filtration units for reducing indoor PM2.5 in homes using a wood stove for primary heating. We also discovered that using lower efficiency, lower cost filter alternatives can be effective for reducing PMc and airborne endotoxin in homes burning biomass fuel.
