Abstract:

With the development of industry and agriculture, human activities are leading to the increasing pollution of soil polycyclic aromatic hydrocarbons (PAHs) such as heavy use of chemical fertilizer and pesticides, oil exploitation, transportation, etc. The pollution of PAHs in soil has become an urgent problem to be solved by the world. Studies showed that degradation was the most leading way to remove PAHs from soil. To further understand recent situation of soil PAHs degradation research, relevant literatures from 2000 to 2017 were studied with quantitative analysis by selecting the collection database of the Web of Science core. The results showed that the number of published papers generally increased on a world wide scale, the number of China’s publications ranked the first, followed by that of the United States. The number of published papers by Chinese Academy of Sciences and Nanjing Agricultural University ranked the top two among global research institutions. The key journals in this field were International Biodeterioration Biodegradation, Journal of Hazarodous Materials and Chemosphere, etc. At the same time, the key words of the 15 years were analyzed and the hot direction of PAHs degradation research was pointed out. Of which, the relevant research carried out by China was extremely important. This study describes the research status in the field of PAHs degradation in soil environment worldwide, and provides certain references for further research in this field in China.
