我国垃圾焚烧过程汞的现状研究——基于CNKI文献计量分析

Study on mercury pollution status in domestic waste incineration process based on CNKI literature measurement analysis

汞是环境中具有迁移性、持久性和生物蓄积性很强的重金属元素之一,其中燃煤发电和垃圾焚烧是环境中重要的人为汞排放源。为更好的了解我国国内垃圾焚烧过程中汞的研究状况,本文依据CNKI中国期刊全文数据库采用文献计量学方法对主题词为"垃圾焚烧"和"汞"的相关文献进行了统计分析,以客观反映国内垃圾焚烧过程中的汞污染现状。结果表明,国生活内对垃圾焚烧过程的汞的研究文献的数量基本呈上升趋势;该领域的研究以北京大学和清华大学等高校为主;研究重点向垃圾焚烧过程中汞污染的时空分布特征及对周边环境危害的方向偏重。

Mercury is one of the heavy metals in the environment with strong migration, persistence and bioaccumulation, among which coal-fired power generation and waste incineration are important anthropogenic sources in the environment. For a better understanding of our domestic study status of mercury in the process of waste incineration, this paper using the method of literature metrology subject to ＂waste incineration＂ and ＂mercury ＂ based on CNKI China journal full-text database. Statistical analysis of related literature to objectively reflect the current state of the mercury in the process of domestic waste incineration. The results showed that the number of domestic research literature is basically on the rise. The research in this field is dominated by the Peking University and Ts- inghua University and other colleges and universities. The research focus on the temporal and spatial distribution characteristics of mercury pollution in the garbage incineration process and direction of harm to the surrounding environment.
