並列タイトル等北九州市における大気中エアロゾルの特徴--発生，二次生成，削減機構とリスクアセスメント
一般注記The sampling campaign of atmospheric aerosols was carried out in Kitakyushu, Japan. Secondary inorganic aerosols (SIA) had the largest contribution (45%) for total particle mass concentration. Moreover, the reduction of TSO42- concentration showed the relatively large decreasing amount of inorganic aerosol mass concentration (IAM) and the significant increase of aerosol pH, with corresponding fitting equations of yIAM = -12.89x + 10.47x2, and ypH = 0.97x + 0.54x2, respectively (yIAM, ypH, and x presents the IAM variation [μg·m-3], inorganic aerosol pH variation [dimensionless], and concentration reduction ratio (CRR)/100 [dimensionless]). In addition, the exposure of particle-bound heavy metals could exert significant influences on the ecological environment and children’s health; control of ship emissions should be given priority. Overall, our results clearly demonstrate the characteristics of atmospheric particles, providing policy makers with basic and effective ideas for mitigating particle pollution from two perspectives of air quality and human health.
