Abstract:
To explore the feasibility of the application of LD 1 laser dust monitor to determination of inhalable particulates(IP) in indoor air of public places, and provide basis for establishment of national standard method of detection of IP in indoor air of public places LD 1 laser dust monitor and weighing filter paper method were applied in monitoring the concentration of IP in indoor air of 4 kinds of public places in Changzhou in four seasons simultaneously Significant correlation was observed between mass concentration and relative concentration ( r =0 7526, P
