随着工农业的发展,河流重金属污染问题越来越受到人们的重视。近年来,全球对河流重金属污染的研究力度不断增大。利用Web of Science引文数据库,对1979—2016年间收录的相关文献进行了计量分析。结果表明:河流重金属污染研究的文献量增长速度较快,西班牙、美国和法国等国的河流重金属污染研究论文综合影响力较高,中国发表论文的总量和总被引次数虽然最多,但篇平均被引次数较低。来自西班牙维尔瓦大学的Grande在该领域研究实力较强,Environmental Pollution是河流重金属污染研究领域最值得关注的期刊。研究的热点主要集中在河流沉积物,而汞、镉、铅、砷、锌、铜等是河流的主要重金属污染物,受关注度较高,同时基于生物监测的重金属污染评价也逐渐成为研究热点。
Abstract
Heavy metal pollution in river has received increasing attention around the world with the development of industry and agriculture. In the present paper, papers on heavy metal pollution in rivers indexed by the Web of Science from 1979 to 2016 are analyzed. Results indicate that the number of articles on heavy metal pollution in river is increasing rapidly. Articles in Spain, United States of America, and France are of strong comprehensive impact. Although the number of articles and total citations of Chinese articles are the highest all over the world, the average citation per article is lower. Grande, an author from University of Huelva in Spain is very competent in research on this field. Environmental Pollution is the most important journal in the research field of heavy metal pollution in river. Sediment in river is the hottest topic. Mercury, cadmium, lead, arsenic, zinc, and copper are the major heavy metal pollutants in river. The assessment of heavy metal pollution based on biological monitoring has also become a focus recently.
