The analyzed results of the heavy metal concentration of air and soil at the D iron-manufacturing company area were as follows; The concentration of $PM_{2.5}$ in the case area exceeded the air standard level in 3 seasons except summer. The $PM_{10}$ level was similar to the standard level, which was similar to the standard level, which was $50{mu}g/m^3$. The Pb concentration of air in the case area was $0.13{mu}g/m^3$, which was slightly higher than $0.11{mu}g/m^3$ in the control area. The concentration of Cd and Cr were higher in the control area. The heavy metal (Pb) concentration of soil in the case area was $10.7{mu}g/m^3$, which was higher than that of the control area. For these results, it is necessary for the D iron-manufacturing company area to consider a counter plan for dusts and are duction plan for the heavy metal (Pb).
