Introduction

  • Suspended particle pollution has become a critical problem in Taiwan. Emissions of air pollutants in Asia have been increasing drastically in past decade.

  • Particulate matter (PM) has been given much attention in recent decades due to its potential adverse health impact and the subsequent need to have a better control or regulate these pollutants.

Results and discussion

  • Table 1 shows the sampling information of total suspended particulate, coarse and fine particulate concentrations and meteorological conditions such as temperature, relative humidity, atmospheric pressure and prevalent wind direction at Taichung airport (TA) sampling site during September to December of 2005.

Conclusion

  • As for the metallic concentrations in TSP, coarse and fine particulates, the metallic elements of Fe and Mg were the main metallic elements at TA sampling site.

  • The results obtained in this study indicated that the metallic elements Fe, Mg and Zn occupied about 60 - 80% average metallic concentrations percentage out of the total metallic elements around traffic, Harbor and airport in central Taiwan.
