Abstract

|
|
Air pollution in Gwangju area was examined for 12 months from Jan, 1978 to Dee, 1978. The surveyed area was divided into four; Industrial, Commercial, Residential and Park area. Ten 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 oxid Deposit Gaug method for Dustfall, and the RION noise meter for Noise Level.
The results we obtained are as follows.
1. Sulfuroxides
The mean of Sulfur oxides was 2.519㎎SO₃/day/10.0㎠PbO₂, ranging from 1.78 to 3.11 ㎎SO₃day/100㎠PbO₂. The mean value of Sulfur oxides was 2.903㎎SO₃/day/100㎠ PbO₂ for Residential area, 3. 108㎎SO₃/day/100㎠PbO₂ for Commercial area 1.775㎎SO₃/day/100㎠PbO₂ for Industrial area, and 2.251㎎S0₃/day/100㎠PbO₂ for Park area, respectively.
2. Nitrogen Dioxides
The mean value of Nitrogen dioxides was 31.529㎍NO₂/day/100㎠, ranging from 23.692 to 46.255㎍NO₂/day/100㎠. At Commercial area whene the value was the highest, the rance of Nitrogen oxides level was 14.45-62.458 ㎍NO₂/day/100㎠.
3. Dustfall
The mean value of Dustfall was 42.53 ton/㎢/month, ranging from 24.36 to 55.93 ton/㎢/month. The Dustfall for Residential area was higher than any other area.
4. Noise
The mean value of noise level was 62 dB(A), ranging from 43 to 79 dB(A).
The Noise of 70.3 dB(A), at Commercial area was higher than any other area.
