Physico-chemical characteristics of dust aerosols deposited during the Soviet-American experiment (Tadzhikistan, 1989)

Abstract

Bulk filtration and sedimentation samples of soil-derived aerosol were collected during dust storms in Tadzhikistan (Soviet Central Asia) during September 1989. This study describes results about morphological, chemical and mineral characteristics of dust. The data obtained may be useful in determining the origion of the dust deposited over the sampling sites. It is suggested that the source region of the dust differs from the sampling sites and that the soil of this source area is rich in quartz and calcium carbonate.
