Characteristics and variations of fall-dust in the Lanzhou urban district
Thirty two elements and seven water-soluble anions in fall dust samples at the Lanzhou urban district during September 1993 to August 1994 were determined by instrumental neutron activation analysis(INAA) and ion chromatography(IC)
respectively The enrichment factors(EF) of the elements were also calculated
and the chemical compositions
distributions and seasonal variations of all the elements and anions in the fall dust were preliminarily studied
