영문 초록

This study was carried out to investigate the concentrations of Ni, Cr and Cu, to analyze the correlations among those, and between concentrations and traffic volumes by type of car in roadside ambient air at Chongro-, Chungkechon- and Kangnam terminal- area in Seoul from October 1st to October 31st in 1997. The results were as follows ; 1. The means of concentrations of Ni in roadside ambient air were 34.1, 25.1 and 23.6 ng/m3 at Chungkechon, Kangnam terminal and Chongro area, respectively. The highest concentrations of Ni by time were 26.8 in the evening, 45.5 in the evening and 49.4 ng/m3 in the forenoon at Chongro, Chungkechon and Kangnam terminal area, respectively. 2. The means of concentrations of Cr in road side ambient air were 97.7, 80.1 and 70.9 ng/m3 at Chong, Chungkechon and Kangnam terminal area, respectively. The highest concentrations of Cu by time were 205.3 in the evening, 114.4 in the evening and 92.3 ng/m3 in the forenoon at Chongro, Chungkechon and Kangnam terminal area, respectively. 4. The tendencies of concentrations of Ni and Cr by time were similar to each other. Especially, at Kangnam terminal area, correlation coefficients between concentrations of Ni and Cr and the traffic volume of bus were high(r=0.997,0.975). 5. The tendency of concentration of Cu and the traffic volume of passenger car at each area were high(r=0.832, 0.968) 6. Correlation coefficients between Cu and Zn, and between Ni and Cr were 0.762 and 0.842, respectively. This means that the possibility of co-existence of Cu-Zn or Ni-Cr is very high.
