Airborne carbonaceous particles with diameters from 10-600 nm have a spectacular impact on global climate and human health. Black carbon (mostly solid combustion byproducts known as "soot") may contribute to global warming almost as much as methane, and this same class of particles is probably responsible for the largest number of air-pollution related deaths. However, the impacts are highly uncertain, partly due to the difficulty of measuring these particles, which have irregular aggregate structures, often with organic coatings.

直径在10-600 nm之间的空气含碳颗粒物对全球气候和人类健康有着巨大的影响。黑碳（主要是固体燃烧副产物，称为“煤烟”）可能与甲烷一样导致全球变暖，而这类颗粒可能是造成最多空气污染相关死亡的原因。然而，影响是高度不确定的，部分原因是难以测量这些颗粒，这些颗粒具有不规则的聚集结构，通常带有有机涂层。
