TLDR
In this paper, various types of combustion-related particles in the size range between 100 and 850nm were analyzed with an aerosol mass spectrometer and a differential mobility analyzer, which yielded a fractal dimension (D f ) of 2.09 ± 0.06 for biomass burning particles from the combustion of dry beech sticks, but showed values around three, and hence more compact particle morphologies, for particles from combustion of more natural oak.About:

Smoking Rain Clouds over the Amazon
Meinrat O. Andreae,Daniel Rosenfeld,Paulo Artaxo,Alexandre Araújo Costa,Göran Frank,Karla Longo,M. A. F. Silva-Dias +6 more
TL;DR: Heavy smoke from forest fires in the Amazon was observed to reduce cloud droplet size and so delay the onset of precipitation, which affects the water cycle, the pollution burden of the atmosphere, and the dynamics of atmospheric circulation.

Pulmonary effects of inhaled ultrafine particles.
TL;DR: The hypothesis that ultrafine particles are causally involved in adverse responses seen in sensitive humans is based on several studies summarized in this brief review, and the studies performed so far support the ultrafine particle hypothesis.
