초록

This study evaluated the distribution of the concentrations of nano-particles and heavy metals (08-Pb, Cr, Zn, As, Fe,09-Pb, Cr, Zn, Cu, Ni, Mn) in Seoul, Chungnam A and Gwangyang from August to December, in 2008 5 times each in the Seoul area, 5 times in and Chungnam A area and from August to November, in 2009 14 times in the Chungnam A area, 8 times in the Gwangyang area. The examined results showed high concentration level from PM1 through PM0.1in all three areas. These results were obtained the concentration of particles by diameter and statistically significant in Stage5 (1.0-0.56 μm) from the result of conducting Kruskal-Wallis H test (p < 0.05). In the case of the heavy metal concentration included in 0.10-0.056 μm, 0.056 μm, the lead concentration of Chungnam Asan area was 6.49 ng/m3 and 9.93 ng/m3, which was higher than 3.05 ng/m3 and 4.22 ng/m3 of Seoul, respectively. The concentration of iron in Seoul was 9.28 ng/m3 and 13.24 ng/m3, that appeared higher than 2.38 ng/m3 and 3.23 ng/m3 of Chungnam A area, respectively. The concentration level was similar to other metals except lead and iron in Chungnam A area and Seoul. From the concentration of heavy metal included in 0.10-0.056 μm, 0.056 μm, the lead concentration of Chungnam A area was 0.31 ng/m3 and 0.12 ng/m3 while Gwangyang was 0.28 ng/m3, 0.06 ng/m3. Thus Chungnam A area showed higher lead concentration than Gwangyang. The manganese concentration of Chungnam A area was 0.12 ng/m3 and 0.03 ng/m3while Gwangyang was 0.21 ng/m3 and 0.08 ng/m3. Therefore, the concentration of Gwangyang appeared higher than that of Chunnam A area. These two metals showed statistically significant in 0.056 μm (p < 0.05, p < 0.01). Among the concentration of heavy metal in all regions, the result demonstrated that the order of higher concentration is arsenic >iron > zinc > chrome > lead > nickel > copper > manganese.

Abstract

This study evaluated the distribution of the concentrations of nano-particles and heavy metals (08-Pb, Cr, Zn, As, Fe,09-Pb, Cr, Zn, Cu, Ni, Mn) in Seoul, Chungnam A and Gwangyang from August to December, in 2008 5 times each in the Seoul area, 5 times in and Chungnam A area and from August to November, in 2009 14 times in the Chungnam A area, 8 times in the Gwangyang area. The examined results showed high concentration level from PM1 through PM0.1in all three areas. These results were obtained the concentration of particles by diameter and statistically significant in Stage5 (1.0-0.56 μm) from the result of conducting Kruskal-Wallis H test (p < 0.05). In the case of the heavy metal concentration included in 0.10-0.056 μm, 0.056 μm, the lead concentration of Chungnam Asan area was 6.49 ng/m3 and 9.93 ng/m3, which was higher than 3.05 ng/m3 and 4.22 ng/m3 of Seoul, respectively. The concentration of iron in Seoul was 9.28 ng/m3 and 13.24 ng/m3, that appeared higher than 2.38 ng/m3 and 3.23 ng/m3 of Chungnam A area, respectively. The concentration level was similar to other metals except lead and iron in Chungnam A area and Seoul. From the concentration of heavy metal included in 0.10-0.056 μm, 0.056 μm, the lead concentration of Chungnam A area was 0.31 ng/m3 and 0.12 ng/m3 while Gwangyang was 0.28 ng/m3, 0.06 ng/m3. Thus Chungnam A area showed higher lead concentration than Gwangyang. The manganese concentration of Chungnam A area was 0.12 ng/m3 and 0.03 ng/m3while Gwangyang was 0.21 ng/m3 and 0.08 ng/m3. Therefore, the concentration of Gwangyang appeared higher than that of Chunnam A area. These two metals showed statistically significant in 0.056 μm (p < 0.05, p < 0.01). Among the concentration of heavy metal in all regions, the result demonstrated that the order of higher concentration is arsenic >iron > zinc > chrome > lead > nickel > copper > manganese.
