English Abstract
The objective of this study was to determine the heavy metals in street, outdoor and indoor dust samples in kindergartens (KGs) of Amman area, Jordan.
To achieve this aim, street, outdoor and indoor dust samples were collected from 38 KGs from 4 types of sites during summer season of 2006.
It was found that the average total levels of Cu, Zn, Pb, Fe and Mn in street dust was (23.45, 188.47, 148.05, 8829.68, 67.73 mg/kg), respectively, for outdoors were (4.63, 127.38, 18.48, 8361.10, 57.83 mg/kg) and for indoor dusts were (23.51, 262.78, 71.33, 5566.14, 51.28 mg/kg), respectively. The chemical fractionation for all sites (street, outdoor and indoor dust samples) showed that Copper is mainly associated with (organic fraction) (61.01%, 64.24% and 75.20%), respectively.
Zinc is associated mainly with (Fe-Mn oxides) (41.43%, 43.24% and 37.91%), respectively.
Lead is associated mainly with (Fe-Mn oxides) for indoor and street dusts (61.51% and 48.60%), respectively, while it is associated mainly with (organic fraction) (59.74%) for outdoor dusts.
Iron is associated mainly with (Fe-Mn oxides) (31.44%) for outdoor dusts, while it is associated mainly with (residual fraction) (57.19% and 47.95%) for street and indoor dusts, respectively.
And finally, Manganese is associated mainly with (Fe-Mn oxides) (56.06%, 54.94% and 57.39%) for street, outdoor and indoor dust samples, respectively. Anions (F", CI", Br", N03", P043\ S042") and cations (Na+, K+, Ca2+, NH4+ and Mg2+) were analyzed by ion chromatography. It was found that there were high levels of anions and cations in all dust samples, except for (Br", POy'"and NH4+). The physiochemical properties (pH, Moisture content and organic matter content), were determined for street, outdoor and indoor dusts. Enrichment factors, mobility factor and correlations were evaluated for heavy metals.
The accuracy of results for heavy metals was examined by analysis of SRM.
