SMPS (Scanning Mobility Particle Sizer)를 이용한 안산지역 대기중 초미세입자 (30~500 nm) 분포연구

Abstract

The fine particles in the range of 30∼500 nm are monitored at Hanyang University campus in Ansan using house made DMA(differential mobility analyzer) and commercial CPC (condensation particle counter, TSI inc.) in SMPS mode. The monitoring period is March 16th 2004 through May 7th, 2004. During the monitoring period, Aitken nuclei mode (30∼100 nm) particle concentration has a tendency of increase in the morning and evening hours. However, the accumulation mode (100∼500 nm) particle concentration stays rather stable than that of Aitken mode.
