초록

A new harbor as been constructing in Gadukdo. However, a lot of fugitive dust gas been often generated from construction
site reclaiming sea sand, especially when the Northwester is blown strongly. It has resulted insome appeals
of residents in Gadukdo. In this study, we estimated the amount of fugitive dust caused by new harbor construction
using Fugitive dust formula. Also, the concentration of PM10 for recipient is predicted by AERMOD. The amount of
fugitive dust is 26.56 ㎍/sec·㎡ and 11.84 ㎍/sec·㎡ respectively by the Fugitive dust formula. PM10 outlet concentration
and the amount of fugitive dust increase according to wind velocity and directions. AERMOD is performed
on the basis of weather data and the amount of fugitive dust generated with wind velocity. As a result of AERMOD,
the PM10 concentration of Sunchang and Oinul are predicted over 100 ㎍/㎥. The PM10 concentration of Sunchang
and Oinul are predicted over 130 ㎍/㎥ when wind velocity of northwester in winter is over 11 m/s (Air Quality for
Particulate Matter (100 ㎍/㎥ for 24 hours)). Also, the measured error between AERMOD and actual measurement is
lower than 5%.
