Atmosphic pollutants study of particles ionic species during high wind speed (>7 m s-1) near Taiwan strait in central Taiwan from 2004 to 2005

Abstract

This study monitored atmospheric pollutants during high wind speed (> 7 m s(-1)) at two sampling sites: Taichung Harbor (TH) and Wuci traffic (WT) during March 2004 to January 2005 in central Taiwan. The correlation coefficient (R (2)) between TSP, PM(2.5), PM(2.5-10) particle concentration vs. wind speed at the TH and WT sampling site during high wind speed (< 7 m s(-1)) were also displayed in this study. In addition, the correlation coefficients between TSP, PM(2.5) and PM(2.5-10) of ionic species vs. high wind speed were also observed. The results indicated that the correlation coefficient order was TSP > PM(2.5-10) > PM(2.5) for particle at both sampling sites near Taiwan strait. In addition, the concentration of Cl(-), NO(3) (-), SO(4) (2-), NH(4) (+), Mg(2+), Ca(2+) and Na(+) were also analyzed in this study.
