| Abstract: | Indoor airborne particles concentration of number and mass in the range of 5.6 nm～560 nm were measured by FMPS3091 with print operation,and indoor airborne pollution characteristics were analyzed in comparison with the background concentrations.Particle size distribution was described with fractal dimensions.Results indicated that the concentrations of number and mass of printer particle were far above than that of background respectively.The particles emitted from printer affected primarily on the number concentrations of those with size less than 143.3nm accounting for 99.5% of total number and size less than 93.1nm accounting for 92%.Fractal dimensions of size distribution generated by printer were in the range of 3.654 6～4.527 6.The concentrations of number and mass of printer particle which attenuated slowly could hold a relatively higher level after 10min. |
