| 摘 要： | 通过系统的野外采样并结合室内分析,将研究区分为3个区域:靠近污染源的铜绿山矿区附近、受矿区影响明显的大冶市区以及相对清洁的武汉市中国地质大学校园,研究了苔藓中和降尘中重金属元素质量分数分布特征和来源,进而进行了对应性分析,最后将研究区域与国内外其他地区进行了对比,结果表明:①铜、铁等元素的污染受矿源的影响较大,而铅、锌的污染则与交通等人类活动有较大关系;②苔藓植物对Cu和Zn有较强的吸附能力;③与其他地区相比,铜污染是大冶市有别于其他地区的首要污染特征;④苔藓植物可以较好地指示大气中的污染物来源.

| Abstract: | There are many researches using the moss to monitor the quality and environment changes.This paper studies the characteristics of the heavy metals in moss samples from a mining environment and makes a correlation analysis of the concentrations of the heavy metals in the moss and dust samples collected from the same location.Finally,these features in the studied area are compared with those in other areas.The following understandings are then obtained.Firstly,contents of Cu and Fe in moss are more influenced... |
