燃烧衍生的纳米颗粒（CDNP）直到最近才被可读测量。我们进行了试点研究，以确定固体燃料燃烧过程中的CDNP水平。在15个使用不同燃料类型（即烟煤、无烟煤、木材）和炉灶类型（即便携式炉灶、带烟囱的炉灶、火坑）的中国家庭中，连续监测CDNP的聚集表面积（μm2/cm 3）。收集了燃料燃烧活动的信息，并测量了PM2.5水平。在固体燃料燃烧期间（平均值：228.1 μm2/cm 3）与无燃烧时间（平均值：14.0 μm2/cm 3）相比，观察到了显著的暴露差异。在有烟囱的家庭中，燃烧过程中观测到的浓度水平降低了约四倍（平均值：92.1 μm2/cm 3; n = 9），所有类型的燃料都受到影响。每个家庭的CDNP测量值与各自的PM2.5测量值仅中度相关（r2 = 0.43; p = 0.11）。我们的研究结果表明，家庭煤炭和木材燃烧有助于室内纳米颗粒水平，这并没有完全反映在PM2.5测量中。
Combustion-derived nanoparticles (CDNPs) have not been readably measurable until recently. We conducted a pilot study to determine CDNP levels during solid fuel burning. The aggregate surface area of CDNP (μm2/cm3) was monitored continuously in 15 Chinese homes using varying fuel types (i.e. bituminous coal, anthracite coal, wood) and stove types (i.e. portable stoves, stoves with chimneys, firepits). Information on fuel burning activities was collected and PM2.5 levels were measured. Substantial exposure differences were observed during solid fuel burning (mean: 228.1 μm2/cm3) compared to times without combustion (mean: 14.0 μm2/cm3). The observed levels during burning were reduced by about four-fold in homes with a chimney (mean: 92.1 μm2/cm3; n = 9), and effects were present for all fuel types. Each home’s CDNP measurement was only moderately correlated with the respective PM2.5 measurements (r2 = 0.43; p = 0.11). Our results indicate that household coal and wood burning contributes to indoor nanoparticle levels, which are not fully reflected in PM2.5 measurements.
