The annual emissions of mineral dust
from southern Africa are around 2,300 Mg (approximately 5% of the global annual emissions) and are on the same order of magnitude of those from major recognized sources in Arabia and the deserts of East Asia (Ginoux et al.

Yes, you can reduce the number of spiders in your home by dusting crevices, corners and the spaces under beds and furniture with diatomaceous earth (DE)--a natural mineral dust

It was also suggested that operations that generate non-combustible dusts, such as mineral dust
, also should be excluded.
For some types of aerosols -- including naturally occurring mineral dust
particles -- it isn't clear how they might affect climate.
In fact, models of hot-planet atmospheres do predict that they should be full of black mineral dust
Meskhidze examined how variations in air pollution and mineral dust
affect iron mobilization.
The Factories Inspectorate reported in 1898 that "microscopic examination of this mineral dust
shows the jagged nature of the particles and wherever they are allowed in this manner to remain suspended in the air, injury, more or less serious, ensues for the respiratory organs of the workers."
