Abstract
|
|
|
|
Measurement of dried deposition for air pollutant was investigated in Gwang-ju Health college area for a year. The average value of air pollutants was investigated three times a month. Measured heavy metals and concentration of mass are not co related. Heavy metals were thrown up air as state of large particles and they were moved by wind. Deposition of heavy metals and deposition velocities were high in the order of Fe > Zn >Cu > Pb > Cr and Pb > Fe > Cr > Zn > Cu, respectively. The patterns of deposition velocity of heavy metals for a year were much the same as each other except that Pb is faster than others.
