Lavi, E. Ganor, E. Neeman, S. Brenner] Several cases of transporation and deposition of settling particles following dust storms over Israel, occurring between 1973 and 1987, were experimentally investigated. The storm particles were collected in Jerusalem and Ramat Hasharon, north of Tel Aviv. Meteorological conditions during the storms were examined and classified according to their trajectories into two types: (a) North African and (b) Arabian Desert. The North African type is by far the most common. In the present work, the concentrations of 26 elements (Al, Ba, Br, Ca, Ce, Co, Cl, Cr, Eu, Fe, Hf, K, La, Mg, Mn, Na, Rb, Sb, Sc, Si, Ta, Th, Ti, U, V, and Yb) in settling particles were determined by instrumental neutron activation analysis. The validity of the method was checked by analyzing U.S. NBS Standard Reference Material SRM-1633a; the elemental content found agreed well with the published certified data. Since Al as well as Si were determined through the reactions27Al(n, γ)28Al(2.24 min) and28Si(n, p)28Al, respectively, thermal and epithermal neutron activation was applied in order to determine the contribution of silicon to the total28Al activity. Interpretation of the chemical analyses using Enrichment Factors reveals that settling particles are relatively enriched in Ca probably from the local terrain and in Cl derived from the Mediterranean Sea.
