英文摘要

Dust samples were collected from 38 naturally ventilated houses for 12 weeks. Effects of three variables in two groups each were evaluated: proximity to traffic density (main-and side-roads), cigarettes smoking (smoking and no-smoking), and houses’ age (old and new). No significant differences were identified between the two groups for all variables (p = 0.227-0.247). The average dust loading rate for the entire group was 66.7 +/- 30.9 mg m(-2) week(-1). The average metal concentrations (mu g g(-1)) for the entire group were 58.7 +/- 17.4 for V, 53.8 +/- 12.7 (Cr), 473 +/- 137 (Mn), 9.68 +/- 2.83 (Co), 130 +/- 52.1 (Cu), 241 +/- 65.3 (Sr), 0.827 +/- 0.552 (Cd), 324 +/- 143 (Ba), and 58.9 +/- 28.9 for Pb. Likewise, the average metal loading rates (mu g m(-2) week(-1)) for the entire group were: 4.01 +/- 2.41 for V, 3.62 +/- 1.97 (Cr), 31.9 +/- 18.3 (Mn), 0.662 +/- 0.387 (Co), 8.57 +/- 5.30 (Cu), 16.3 +/- 9.23 (Sr), 0.051 +/- 0.034 (Cd), 21.1 +/- 12.4 (Ba), and 3.97 +/- 2.74 for Pb. We noticed enrichment factors (EF) of less than 2 and strong correlations between V, Cr, Mn, Co, and Sr indicating their crustal origin. Conversely, Pb, Cu, and Cd showed low to moderate correlations together with moderate to significant EF suggesting anthropogenic pollution of non-crustal origins. Despite the scarcity of rain fall and arid environment in the studied area, our dust and metal loading rates can be considered as intermediate when compared to some international cities. Such a finding could be attributed to the absence of major industries and the relatively low traffic density in our study area.
