摘要: 空气中颗粒物的粒径从几十埃到几百微米,差别很大。近年来由于消烟除尘技术的改进,空气中细颗粒与粗颗粒的比率逐年增高。Abstract: The mean concentration of in inhalable particles(IP) in the air of Dalian city was 0.17mg/m3 and was in direct correlation with the pollution level of total suspended particles(TSP).IP amounted to 50% of TSP.The concent rations of various harmful components were different in IP and TSP and were higher in winter than in other seasons.
