Airbone particulate samples were collected during 1989 in the northern Negev desert, Israel, using two Sierra ultra-high-volume dust samplers with cascade impactors on glass-fibre filters. A total of 12 elements were detected, of which only eight were present in relatively high concentrations, as was indicated by using an x-ray spectra XL-LINK system. During the study period, the mean annual airborne concentration was 102 μg·m−3, with a minimum and maximum concentration of 0.17 and 1.376 μg·m−3 per 12 hours, respectively. Eight elements (A1, Si, Ca, S, K, Cl, Fe, and Ti) were found in relatively high concentrations.
