If one has to invoke an additional dust component (most likely a population of carbon dust which does not show the characteristic 3.4μm feature, say, graphite) making an appreciable contribution to AV, one would encounter a severe carbon budget problem (see Snow and Witt, 1996).
Even though such observations cannot identify the population of individual dust particles, a statistical approach using the dataset can address the characteristics of the individual dust particle population, which are their size distribution, time variation, and orbital characteristics.
These include many of the raw materials in civil and chemical engineering, pharmaceutical, and mining industries; pigments, metals, ceramics, pills, foods; industries with interests in population of atmospheric dusts, smoke, and grit.
Three small particles contain sulfide, but others are sulfur-free a hint that sulfur-free ahint sampled thatdifferent populationStardusterstellar dust.
Less-sophisticated instruments used in previous dust observation missions, however, have provided much insight into our understanding of dust populations in interplanetary space, although they could not determine accurate trajectories of detected dusts.
The resulting population is compared against the existing background population of SRM slag and dust particles in terms of spatial density and flux predictions.
Let's say that two thirds of the world population thinks dust bunnies should not be given a place in zoos.
This suggests that there may be more endotoxin attached to the dust collected from our study population but a lower overall burden of endotoxin in the homes, possibly due to less dust or smaller size of dust particles than in other study populations.
