选择2006年4月30日至5月10日,结合"五一"长假前后参观游客数量的变化,对莫高窟室内外总悬浮颗粒物(TSP)和污染气体进行了为期2周的加强连续观测,获得了莫高窟室内外大气环境污染的初步数据.在观测期内,室外、非开放洞窟[320窟]和开放洞窟[257窟]大气TSP的日平均质量浓度分别为1138.4μg·m~(-3)、228.5μg·m~(-3)和286.4μg·13~(-3).TSP中水溶性离子分析表明,Ca~(2+)、SO_4~(2-)、Na~+和Cl~-是水溶性无机离子的主要组分,且室外水溶性离子浓度高于窟内水平,长假前后水溶性组分浓度有明显变化.碳气溶胶分析显示,开放洞窟相对于室外和非开放洞窟具有较高的碳气溶胶的浓度水平.获得了研究区NH3和气态HNO3的浓度水平.游客数量对TSP质量浓度,水溶性离子浓度,碳气溶胶浓度和污染气体均有显著影响,旅游高峰期污染物质浓度显著增高. |

Mass concentrations,water-soluble ions,and total carbon(TC) of total suspended particle(TSP) were investigated from both indoor and outdoor conditions in Mogao Grottoes,Dunhuang,from April 30 to May 10,2006.The average outdoor mass concentration was 1138.4μg·m~(-3),while the indoor average mass concentrations were relatively very lower,about 228.5μg·m~(-3) and 286.4μg·m~(-3) for non-opening time and opening time,respectively.The water-soluble ions are predominated by Ca~(2+),SO~(2-)_4,Na~+ and Cl~-.The concentrations of water-soluble ions from outdoor aerosols were higher than those from indoor aerosols and the concentrations of water-soluble component varied significantly during the long-term vacation period.The TC concentrations collected during the opening time were higher than those collected during the non-opening time and those collected from the outside of the Grottoes.The concentrations of NH_3 and HNO_3 gasses were also obtained in this study.Our study showed that there was a remarkable increase in the pollution material concentrations at the peak of the tourist populations,indicating the significant influence from the tourists. |
