城南市 大氣浮遊粉塵 中 重金屬의 季節別, 粒徑別 特性 = Properties of Heavy Metal Pollutions in the Airborne Suspended Particulate at Sung-Nam City

다국어 초록 (Multilingual Abstract)

Sungnam city, as a major satellite town, is located in the southeast of Seoul. Atmospheric conditions are so stable that air pollutants from various emissions are tend to resist change because Sungnam city is located in the Namhansansung valley. The industrial distribution of Sungnam city are composed of various manufactories such as foods, fibers, chemicals, machinery and electronics, etc.
The heavy metal concentrations and size distribution are the most important parameters influencing among the way in which respirable suspended particulate matter interact with the human respiratory system.
Respirable suspended particulate matter was collected on glass fiber filters from April 1993 to February 1994 according to particle size using Andersen sampler during 10 days per month at Sungnam city.
6 heavy metals, Fe, Zn, Ph, Mn, Cu and Cd, were analyzed by particle size with atomic absorption spectrophotometry.
The results could be summerized as follows:
1. The annual arithmetic mean concentration of total suspended particulates was 116.3㎍/㎥, seasonal variation was the highest in spring season096.5,ug/m') and the lowest in summer season(72.9 ㎍/㎥)
2. The ratio of airborne particulate concentrations respirable to nonrespirable(Res/NonRes) of annual arithmetic mean value was 5.8 : 1, seasonal variation was highest in the spring season(6.3 : 1) and lowest in the summer season(4.6 : 1).
3. During the spring season the shape of the size distribution was trimodal which showed peaks at 3 size groups, which were below of 0.43㎛, 3.3-4.7㎛, and above of 11.0㎛, respectively.
4. Respirable suspended particulate matter concentrations of Zn, Ph, Cu and Cd were the highest in below of 0.43㎛ as follows; 0.517㎛/㎥, 0.411㎛/㎥, 0.062㎛/㎥ and 0.0310㎛/㎥', respectively, Fe and Mn were the highest in the particle size range of 4.7-7.0㎛ as follows; 2.504㎛/㎥ and 0.095㎛/㎥, respectively.
5. The Ph, Cd, Zn, Cu, Fe and Mn concentrations of annual arithmetic mean value respirable to non- respirable(Res/Non- Res) were 33.65, 19.27, 17.74, 10.54, 3.20 and 5.20, respectively.
