为明确焦化场地多环芳烃(PAHs)污染土壤修复技术研究现状及未来发展趋势,采用文献计量学方法统计分析了Web of Science(WoS)数据库中关于焦化场地PAHs污染土壤修复技术的文献资料,并从发文数量及其年度变化、发文国家及机构、发文作者、论文关键词、发文期刊以及共被引文献等方面进行分析.结果表明:WoS数据库中焦化场地PAHs污染修复技术研究型论文共 419 篇,近年来世界范围内该领域总体发文数量总体呈上升趋势;中国、美国和法国是该领域发文数量位居前三的国家,共计 98 家研究机构、1 070 名作者参与焦化场地PAHs污染修复领域研究;研究主要集中在自然科学领域,发文量排名前 3 的期刊分别是Science of The Total Envionment、Chemosphere和Environmental Science and Pollution Research;关键词分析表明,焦化场地PAHs的源解析、风险管控、修复技术将会成为未来主要研究方向.
Study Progress on the Remediation Technology of Polycyclic Aromatic Hydrocarbons Contaminated Soil in Coking Sites
In order to clarify the research status and future development trend of polycyclic aromatic hydrocarbons(PAHs)remediation technology in coking sites,bibliometrics method was used to statistically analyze the literature on polycyclic aromatic hydrocarbons remediation technology in the Web of Science(WoS)database.The results showed that there were 419 research papers on the remediation technology of polycyclic aromatic hydrocarbons in the coking site in the WoS database;China,the United States,and France are among the top three countries in terms of the number of publications in this field;A total of 98 research institutions and 1 070 authors participated in the research on polycyclic aromatic hydrocarbons remediation technology in coking sites;Keyword analysis shows that the remediation of polycyclic aromatic hydrocarbons in coking sites and the control of removal efficiency of various remediation methods are the focus of research.The combination of classic repair technology and other technologies can achieve better processing results and higher efficiency,which will also be the main research direction in the future.
