황사현상시에 성남시에 포집한 분진한 입경분포 및 중금속 농도 = The Particle-Size Distribution and Heavy Metal Concentration of Suspended Particulates Collected in Sung-Nam Area During the Period of Yellow Sand Phenomena

다국어 초록 (Multilingual Abstract)

The heavy metal concentrations and size distribution are the most important parameters influencing among the way in which airborne suspended particulate matters interact with the human respiratory system.
Airborne suspended particulate matters were collected on a glass fiber filter from April to May 1996 using high-volume air sampler and Andersen sampler at Sungnam City.
And those of Yellow Sand Phenomena period were investigated to find out the characteristics between normal and Yellow Sand Phenomena period.
The results could be summerized as follows :
1. The Yellow Sand Phenomena period of TSP concentration was 264.7㎍/㎥ and normal period of TSP concentration was 117.5㎍/㎥.
2. The Yellow Sand Phenomena period ratio of PM-10 to TSP(PM-10/TSP) was 19.6% and normal period of PM-10 to TSP(PM-10/TSP) was 27.9%.
3. During the period of Yellow Sand Phenomena, the ratio of coarse particles to TSP was 70.7%.
4. The heavy metals were analyzed as follows showing in order of high concentration: Fe>Si> Na>Zn> Mn> Pb>Cu> Ni>Cd.
5. The mass median diameter(MMD) of Ni, Cd, Zn, Pb and Cu were 0.73, 1.07, 1.67, 1.77 and 1.79㎛, respectively, Na, Si, Fe and Mn were 2.66,4.87,5.12 and 5.84㎛, respectively.
6. Those with MMD smaller than about 2㎛ are commonly associated with anthropogenic processes, in contrast, MMD greater than 2㎛ are emitted mainly by natural processes.
