蝙蝠对快速工业化中重金属污染的指示作用研究

Some bats have become good models for the research of bioindicator due to bioaccumulation of heavy metals. Previous studies have quantified the residues in bat’s hair and preliminarily proved its suitability as indicator tissue for heavy metal pollution. However, the study areas thereof were mostly post-industrialization countries, so the concentrations were low and not able to reflect temporal and spatial pattern clearly. In order to have a systematic and comprehensive test of bats’ suitability as bioindicator based on the previous analysis, we collect hair samples of four bat species from Sichuan and Yunnan, measure cadmium (Cd), arsenic (As) and lead (Pb) concentrations, and then present their temporal and spatial patterns. Accompanied with the rapid industrialization of these regions during the past dozens of years, the situation of heavy metal pollution has become more and more serious. In terms of economy development, industrial structure, inner structure of industry, employment structure and urbanization, we evaluate the real-time regional industrialization of sampling sites to assess the effectiveness of bat as bioindicator of heavy metal contamination during the rapid industrialization.

重金属的生物富集使得一些蝙蝠类群成为研究生物指示的良好模型。前期的研究也对蝙蝠毛发重金属残留进行过检测，并初步证明其对污染源的指示作用。然而其研究区域多为后工业化国家，因此含量低，且难以反映出时空格局和变化。为了在前期的基础上更加系统以及全面地去验证蝙蝠作为重金属指示生物的有效性，我们将收集四川和云南多个采集地的四种蝙蝠毛发样品并测定其镉、砷和铅残留含量数据，之后分析其时空格局。伴随着该地区过去数十年间的快速工业化，重金属污染形势日趋严峻。我们从经济发展水平、产业结构、工业结构、就业结构、空间结构等多方面评价采集地当年的地区工业化水平，以评估蝙蝠对快速工业化进程中重金属污染的指示作用。
