摘要：Particles have become an important factor in environmental quality of heritage preservation. Aiming to explore the air quality of the museum, this study conducted a series experiment in a museum in Shanghai, China. The result showed that the mass concentrations indoors of coarse particles, fine particles and ultrafine particles were about 20.50～24.38μg/m, 23.39～24.08μg/m and 16.02～17.48μg/m, respectively. Over 97 % of particles were belonged to PM1 (diameter 42-, NO3-, NH4+ peaked at the particle size ranged from 0.32 to 0.56μm; Na+, Cldistributed uniformly; K+ appeared bi-modals with peaks in the size ranges of 0.32～0.56μm and 3.2～5.6μm, respectively. Mg+ concentrated in size range of 3.2～5.6μm, and Ca+ in the particles with size range of 1.8～3.2μm. Total organic acids distributed uniformly, acetate ion mass concentration was 1.238μg/m which was higher than formate ion and oxalate ion.
