The characteristics and distribution of metal contents emitted from a power plant fueled by heavy oil and its impact to
the ambient atmosphere near the power plant was investigated. The current investigation measured toxic (As, Cd, Cr, Hg,
Ni and Pb), anthropogenic (Ba, Cu, Mn, Sb, Se, Sr, Ti, V and Zn) and crust (Al, Ca, Fe, K and Mg) elements from a 2,000
MW heavy oil-fired power plant. Results showed the emission concentration from the power plant contributed to 17,976
kg/yr annual emission of anthropogenic elements, which was significantly higher than those from some electrical arc
furnaces and coke ovens in Taiwan. For toxic metals, As, Cd or Ni concentration do not exceed target values established
by the European Council (2004/107/EC) for As (6 ng/m 3 ), Cd (5 ng/m 3 ) and Ni (20 ng/m 3 ). This study also applies
nonparametric statistical analyses for evaluating the relationship between metal concentrations and operational parameters
(including emitted CO 2 , O 2 , flue gas emission temperature, flue gas velocity, moisture, heavy oil consumption rate, boiler
steam temperature, boiler operational pressure, and electricity). Findings show negative correlations between most toxic
metals (As, Cd, Cr and Hg) and operational parameters, though some pairs were not statistically significant. The current
study provides only preliminary statistical results between metal concentrations and operational parameters due to small
sample sizes. Further investigation requires larger sample sizes.
