To investigate the pollution realities of the neighborhood area by aerosol of a smelting factory, sampling of water, sediments, soils and aerosol were carried out from the village that is situated around the smelting factory to 4km up-downstream, and were analyzed by standard method. As a result, it was found that study area is influenced by heavy metal(Zn, Cd) in aerosol, and if the countermeasure is not considered for heavy metal in aerosol, that is exhausted in the smelting factory, it is expected that inflow of heavy metal in study area is continued.
