Atmospheric aerosol particles were investigated at GNTECH university in Jinju city. Samples were collected using the Nanosampler period from January to December 2014. The Nanosampler is a 6 stage cascade impactor(1 stage : gt; $10{ mu}m$ , 2 stage : $2.5{ sim}10{ mu}m$ , 3 stage : $1.0{ sim}2.5{ mu}m$ , 4 stage : $0.5{ sim}10{ mu}m$ , 5 stage : $0.1{ sim}0.5{ mu}m$ , back-up : $0.1{ mu}m$ ) with the stages having 50% cut-off ranging from 0.1 to $10{ mu}m$ in aerodynamic diameter. The mass size distribution of Atmospheric aerosol particles was unimodal with peak at $1.0{ sim}2.5{ mu}m$ or $0.5{ sim}1.0{ mu}m$ . The annual average concentrations of TSP, $PM_{10}$ , $PM_{2.5}$ , $PM_1$ , $PM_{0.5}$ and $PM_{0.1}$ were $44.0{ mu}g/m^3$ , $40.3{ mu}g/m^3$ , $31.4{ mu}g/m^3$ , $18.0{ mu}g/m^3$ , $8.0{ mu}g/m^3$ , $3.0{ mu}g/m^3$ , respectively. On average $PM_{10}$ , $PM_{2.5}$ , $PM_1$ , $PM_{0.5}$ and $PM_{0.1}$ make up 0.91, 0.70, 0.41, 0.19 and 0.07 of TSP, respectively. The annual average of $PM_{2.5}/PM_{10}$ ratio was 0.77. |
