A bibliometric and visualized analysis of research progress and frontiers on health effects caused by PM2.5

Abstract

Fine particulate matter (PM 2.5 ) is one of the major air pollutants. A large number of epidemiological and experimental studies have shown that PM 2.5 pollution can cause adverse health consequences, which has attracted more public attention. In order to have a deeper and more structured understanding of the research progress and frontiers on the impact of PM 2.5 on health, in this study, we used the bibliometrics software CiteSpace to analyze the relevant literature in this field. The results show that since 2000, the relevant literature has increased steadily, especially in the last 5 years, and the number of publications in China has increased rapidly. The United States has the most publications. The Chinese Academy of Sciences and Professor Joel Schwartz are the most published institution and author, respectively, and many articles have been published in the journal of Environmental Health Perspectives . Over time, studies on the health effects of PM 2.5 have gradually deepened. In addition to a more comprehensive study of its harmful effects, the related molecular mechanisms have also been further explored. We believe that countries and regions should strengthen cooperation and jointly solve the harm caused by PM 2.5 through the integration of multiple disciplines and fields. In addition, the adverse health consequences and its related mechanisms caused by exposure to ultrafine particle, different chemical components of PM 2.5 , as well as the intervention of the health effects caused by PM 2.5 need to be further studied.

Scientometric and multidimensional contents analysis of PM2.5 concentration prediction

“…Based on the visual bibliometric software CiteSpace for analysis, the options of discipline, country, institution, author, journal, and prominent papers are selected in the software to discuss the specific analysis results [ 23 , 24 , 29 ]. In the knowledge maps analysis of PM 2.5 concentration prediction research, the following three evaluation indexes are used: the frequency, the betweenness centrality, and the burst strength [ 30 , 31 ].…”

“…In addition, previous scientometric papers on air quality research mainly focused on Haze or PM 2.5 [ 19 , 20 ], indoor air quality [ 21 , 22 ], air pollution and human health and health effects caused by PM 2.5 [ 23 ], but there are lack reviews of predictive studies on air quality forecasting, especially for some key air pollutants concentration forecast. A few existing bibliometric reviews on air quality forecasting whose research objects are all air pollutants are mainly focused on employing AI techniques [ 24 ], while there is a lack of systematic and comprehensive review on PM 2.5 concentration prediction.…”

A Bibliometric Analysis on Research Regarding Residential Segregation and Health Based on CiteSpace

“…In this context, CiteSpace, as a visualization software for bibliometrics, has been broadly used for literature-based research and the writing of reviews [ 50 , 51 ]. Studies have been conducted using CiteSpace to provide a panoramic perspective on the development of various health disciplines [ 52 , 53 ]. The software identifies the central knowledge domain, key research topics, and development trends in a certain field through visual knowledge maps grounded in keyword co-occurrence, document co-citation clustering, and burst detection [ 54 , 55 ].…”

The Role of Environmental Health in the Prevention and Control of Environment-Related Diseases Worldwide

“…China, as one of the leading economies in the world, also added its PM2.5 concentration limit to its standards in 2012 (32).…”
