摘要：大气中的颗粒物已经成为影响文物保存环境质量的重要因素之一,监测文物保存环境中颗粒物浓度、减少其对文物所造成的损害影响已成为一个重要的研究课题。目前国内在此方面的研究尚较缺乏。因此,本研究采用气体悬浮物粒子监测仪对某封闭式博物馆不同展厅空气中不同粒径颗粒物的数浓度进行了连续监测,并与游客流量及装饰材料的相关性进行了分析。结果表明,96%以上颗粒物为PM_(1.0)(等效体积粒径小于1.0μm),80%为PM_(0.3)(等效体积粒径小于0.3μm)。游客扰动对颗粒物数浓度的影响与粒径大小有关,PM_(1.0)数浓度没有明显的日变化,但1.0μm以上粗颗粒在开馆时段和夜间清扫时段出现明显的波动;节假日浓度明显高于工作日。上述研究表明,馆藏文物保存环境大气中的颗粒物污染监控应以细颗粒为主。
Air - borne particles have become an important factor affecting the preservation of cultural heritage objects. Monitoring the concentration of particles in the environment of cultural relics, with a view toward preven- ting damage to these relics has become an important research subject. Up to now there has been little research on this subject in China. A suspended airborne particle counter was used to continuously monitor size -fractionated particulate matter （PM） mass in different display halls of a closed museum, and their concentrations in response to visitors is discussed in this paper. The results indicate that over 95 % of the particles are PM05 （ particle diameter 〈 0.5 μm ） and nearly 80% are PM03 （ particle diameter 〈 0.3 μm）. The impact of visitors on PM number concentra- tion depends on the particle size. The concentration of PM1.0 particles changed little during the entire day, while those particles with PM 〈 1.0μm showed two peaks： during the morning opening time and during the nighttime cleaning time. The concentration of PM during the holidays was found to be significantly higher than on working days. The studies suggest that in the interest of preserving cuhural heritage objects, ambient air particulate pollution monitoring should focus on fine particles.
