国庆黄金周期间兵马俑博物馆室内气溶胶有机碳与元素碳特征

Characterization of Indoor Atmospheric Organic and Elemental Carbon Inside the Museum of the Terracotta Army During the National Days

为了研究碳气溶胶，包括有机碳与元素碳对陶质文物的表面腐蚀、彩绘脱失的影响，本文中于国庆黄金周期间（10月1-14日）对兵马俑博物馆一号坑（Pit No．1）和馆外（Outdoor）进行连续两周采集的碳气溶胶进行有机碳、元素碳组分的分析。结果表明：国庆黄金周期间（10月1～7日）馆内碳气溶胶明显高于馆外，有机碳与元素碳分别为馆外的2．3与1．6倍，馆内碳气溶胶占气溶胶组分的42．1％，表明受到大量游客的影响；10月8～14日期间馆内碳气溶胶略低于馆外，且与馆外浓度变化一致。

In order to research the effects of carbonaceous aerosol including organic carbon （OC） and element carbon （EC） on the color, surface erosion and deposition of terracotta figures, it was focused on carbonaceous aerosol sampling at indoor （Pit No. 1 ） and outdoor of the Museum of the Terracotta Army during the National Days. The results showed that the indoor carbonaceous aerosol was higher than that of outdoor especially during Oct. 1 st to 7th, the concentration of OC and EC was 2.3 and 1.6 fold of outdoor, and the indoor carbonaceous had account for 42.1% of aerosols, which was suggested the effect of mass visitors. The indoor carbonaceous aerosols declined during the following days （Oct. 8th to 14th） and showed the same variation trend with the outdoor aerosols.
