摘要

The dust samples of table fans and ceiling fans were collected from 30 sites including residential areas near cities and remote areas from Peninsular Malaysia. These dust samples were analysed for the concentrations of Cd, Cu, Ni, Pb and Zn. The Cd concentrations ranged from 2.48 to 20.76 ug/g (mean: 6.87 + - 0.80 mu g/g) while the Cu concentrations ranged from 27.12 to 3264 mu g/g (mean: 273.45 + - 106.89 mu g/g). For Zn, they ranged from 101.84 to 1848 um g/g (mean: 691.33 + - 61.20 mu g/g). For Pb, they ranged from 165 to 843 mu g/g (mean: 464.01 + - 30.89 mu g/g) while for Ni, they ranged from 16.8 to 1927 mu g/g (mean: 117.11 + - 62.65 mu g/g). The wide ranges of heavy metal concentrations in the dust samples indicated that they received variessources of anthropogenic inputs including vehicular combustion, house cooking smokes, smokers' smokes and industries. From the results obtained it can be concluded that the residential areas near major cities had the highest level of heavy metals. On the other hand, sites near forest and recreational areas were found to have low levels of heavy metals in the dust samples. This study signified the significant sources of heavy metal pollution due to anthropogenic sources namely vehicles and industrials.These findings are useful in assessing the potential health hazards in humans.
