|
Water pollution of Yeocheon Industrial Complex was examined from 2. September 1980 to 5. September 1980. For checking the water pollution, 5 sampling positions were selected; we assumed that the water pollution of Yeoch-eon Industrial Complex was due to the oil and metals, which came from industrial materials and oil.
The apparatus for this test were ; pH meter (Fisher accumet 520), Temperature meter (Delta 1010), spectrophotometer (Hitach 181, spectronics 20 L&B 2), Atomic absorption spectoroph.otometer (Hitach 170¡30, Myrano 1).
The results we obtained are as follows.
1. The average range was 6.99¡9.67 of pH, 12.9¡43.85ppm of COD, 9.675¡30.8ppm of BOD, 28.0¡125.25ppm of SS, 388.25¡607.5ppm of VS, 0.6183¡2.4442ppm of phenol, 29.6¡76.375ppmof oil, 4.559¡15.121ppm of T-P,0.55¡0.975ppm of CN,0.040¡0.143ppm of T-Hg, 24.77¡224.075§¶/l of T-Cr, 2,6865¡8.9365ppm of Cu, 0.2018¡0.7035ppm of Cd, 0.24¡1.075ppm of Mn, 0.5951¡3.4521ppm of Pb and 0.0321¡0.1936ppm of Zn.
2. The mean value for havy metals for the st D was 0.143ppm, st B was 0.085ppm, st A was 0.046ppm, st E was 0.041ppm, gtC was 0.040ppm of Hg-, 109.504 §¶/l of T-Cr, 5.0857ppm of Cu, 0.3300ppm of Cd, 0.606ppm of Mn, 2.1331ppm of Pb and 0..0953ppm of Zn.
