Abstract

Concentrations of Cu, Mn, Cd, Pb, Zn, Fe and Al in indoor dusts and outdoor soils from nurseries located in industrial, town and village area of Dungun district were determined by Atomic Absorption Spectroscopy (AAS) following the acid digestion of the respective soil and indoor dust sample. The range of metals observed in soils were 0.46-46.9 µg/g, 23.2-338 µg/g, below detection limit (BDL) -4.66 µg/g, 2.26-130 µg/g, BDL-91.7 µg/g and 5310-114000 µg/g, for Cu, Mn, Cd, Zn, Pb and Al respectively. Although the results showed a relatively low contamination in general, the village areas had appreciably high er level of toxic metals compared to both town and industrial areas for outdoor soils. Atmospheric depositions and the distance from the main roadside appeared to have an influence on the Pb distribution in soils. Industrial areas on the other hand exhibited higher mean concentration of Cu, Mn, Fe, Pb and Zn in their indoor dust compared to town and village areas. Evaluation of enrichment factors suggest that possible sources of Cu, Mn and Zn in indoor dusts could be from internal source.

Jumlah logam berat yang terdapat di dalam tanah dan zarahan di dalam bangunan di kawasan pusat penjagaan kanak-kanak di sekitar daerah Dungun telah ditentukan melalui kaedah spektroskopi penyerapan atom (AAS) setelah dicerna oleh asid. Kajian kepekatan logam berat Cu, Mn, Cd, Pb, Zn, Fe dan Al yang terdapat dalam tanah dan zarahan telah dijalankan di kawasan perindustrian, bandar dan juga kampung. Dari keputusan analisis, julat kepekatan bagi Cu, Mn, Cd, Zn, Pb dan Al di dalam tanah adalah 0.46-46.9 µg/g, 23.2-338 µg/g, di bawah had pengesanan (BDL) -4.66 µg/g, 2.26-130 µg/g, BDL-91.7 µg/g dan 5310-114000 µg/g masing-masing. Walaupun keputusan yang diperolehi menunjukan kepekatan yang rendah secara keseluruhannya, namun begitu kawasan kampung mempunyai kepekatan logam toksik yang tinggi berbanding dengan kawasan bandar dan industri. Untuk Pb, pemendapan udara dan jarak dari jalan raya didapati mempengaruhi agihan kepekatan Pb dalam tanah. Di kawasan industri, purata kepekatan bagi Cu, Mn, Fe, Pb dan Zn dalam zarahan adalah lebih tinggi banding dengan kawasan bandar dan kampung. Nilai faktor perkayaan bagi Cu, Mn dan Zn dalam zarahan menunjukan logam-logam ini berkemungkinan berpunca dari keadaan dalaman bangunan.
