[The investigation of air ion and particulates condition in Tianzhu Mountain].
In order to monitor the distribution of atmospheric air ion and particulates in Tianzhu Mountain region, two observation points were established in Tianzhu Mountain in April, 1989. The results showed that the average concentration of air anode ion was 680/cm3, cathode ion 650/cm3. the range of single electrode coefficient is comfortable feeling, air quality index is 0.71 up to standard B grade (clean air), Total average concentration of suspended particulates was 0.242 mg/m3, average concentration of inhalation particulates was 0.168 mg/m3. Seventy percent particulates had diameters less than 10 microns, and thirty percent greater than 10 microns in total suspended particulates.
