|
Air Pollution in Qwangju area was examined for 12 months from Jan, 1980 to Dee, 1980. The surveyed area was divided into four; Industrial, Commercial, Residential and Park area. Nine surveying sites which were representing the characteristics of each area were selected. The measuring methods were: the Lead dioxide cylinder method for Sulfur oxides, Triethanolamine plate method for Nitrogen dioxid, Deposit Ga㎍e method for Dustfalls and the RION noise meter for Noise Level.
The results we obtained are as follows.
1. Sulfur oxides
The mean of Sulfur oxides was 3.54 ㎎SO₃day/100㎠PbO₂ ranging from 2.26 to 4.87 ㎎SO₃/day/100㎠PbO₂. The mean value of Sulfue of Sulfur oxides was 3.498 ㎎SO₃a/day/100㎠PbO₂ for Residential area, 4.119 ㎎SO₃/day/100㎠PbO₂ for Commercial area, 3.86 ㎎SO₃/day/100㎠PbO₂ for Industrial area and 2.614 ㎎SO₃/day/100㎠PbO₂for Park area, respectively.
2. Nitrogen dioxides
The mean value of Nitrogen dioxides was 43.51 ㎍NO₂/day/100㎠, ranging from 29.96 to 94.96 ㎍NO₂/day/100㎠. At Commercial area whene the value was the highest, the range of Nitrogen dioxides level was 2.39-125.82 ㎍NO₂/day/100㎠.
3. Dustfalls
The mean value of Dustfalls was 39.937 Ton/㎢/month, ranging from 11.28∼147.71 Ton/㎢/month. The Dustfalls for Residential area was higher than any other area.
4. Noise
The mean value of Noise Level was 64.25 dB(A), ranging from 42 to 75 dB(A).
The Noise of 72 dB(A), At Commercial area was higher than any other area.
