박점상,박근호 7개 국립대학교 환경연구 논문집 공동발행 위원회 2002 환경연구논문집 Vol.2 No.1
Suspended particles in the air were captured by high volume air sampler in the 29 sites of south Geyngsang area and measured total suspended particulate (TSP), heavy metals, and ion compounds. The results are following as; The average of TSP is 76.8㎍/㎥ throughout Gyeongnam area, and regional average is 124.9㎍/㎥ in industrial complex, 99.9㎍/㎥ road side area, and 52.9㎍/㎥ residential area. The highest level of TSP is 189.3㎍/㎥ in Yangsan industrial complex area. And the lowest is 34.1㎍/㎥ in Namhae residential area. The artificial contaminant(SO_4^2- and NO_3^-) have higher levels particularly road side area than industrial complex or residential area. Thus, it appears to be affected by emission gas of automobile. Fe is the heavy metal compound which of the highest concentration is 1.919㎍/㎥ in the air and Cd the lowest, 0.001㎍/㎥. In the regional aspect, it appesrs that industrial comples has high levels of Cl^-, Na^+, TSP, and heavry metals such as Zn, Pb and road side area has ion compounds such as SO_4^2-, NO_3^-. And there's no high level of concentration in residential area. The coefficient of correlation between Fe and Mn(P=0.000) is 0.999 in the industrial complex, that of Cr to Cd(P=0.003) is 0.997 in road side, and in the residential area that of Fe to Mn(P=0.000) is 0.867. Also, the correlation between Fe and Mn has totally the highest coefficient which is 0.995.
