We studied the concentrations of $PM_{10}$ and heavy metal in the incinerators around Dong-hae from December 2003 to April 2004. The seasonal mean of $PM_{10}$ concentration was less than the value of environmental standard, the lowest ($36.59mg/m^3$) in spring and the highest ($78.54mg/m^3$) in fall. The measured seasonal heavy metals were Fe $503,44ng/m^3$, Mg $410.85ng/m^3$, Na $134.14ng/m^3$, Zn $24.58ng/m^3$ in spring and Na $315.29ng/m^3$, Mg $48.36ng/m^3$, Fe $44.78ng/m^3$, Zn $23.34ng/m^3$ in summer and Na $88.53ng/m^3$, Fe $33.80ng/m^3$, Zn $20,43ng/m^3$, Pb $6.16ng/m^3$ in fall and Na $4603.72ng/m^3$, Fe $575,26ng/m^3$, Al $411.01ng/m^3$, Cr $203.51ng/m^3$ in winter. The relationship between measured metals concentrations showed that Na and Fe were associated with natural sources such as soil. Pb, Cr and Zn were strongly related to urban anthropogenic sources such as fuel combustion.
