In order to clarify theconcentrations, morphology, and origin of particles
transported in the free troposphere around 3,000 m altitude size segregated collections of aerosols were carried out by use of a five-stage cascade impactor (Nano sampler). Concentrations and
transformation of aerosols during long-range transport were analyzed. Because of troubles in analyzing instrument, sample analyses have not finished yet.
Taiwan group did sampling for analysis of gaseous and
particulate mercury. Chemical analyses have not finished yet, either.
