Abstract
Air pollution has been recognized as a significant environmental risk factor with potentially adverse effects on women’s reproductive health. This study presents the existing literature on air pollution exposure and its link to spontaneous abortion (SAB) utilizing a systematic literature review (SLR) and bibliometric analysis (BA). Firstly, SLR was employed to collect relevant articles based on specified inclusion/exclusion criteria and formulated research questions. Secondly, BA was used to map and assess research trends, current knowledge, and structure using network analysis constructed on citation, co-citation, co-occurrence, and collaboration patterns among articles, authors, keywords, and institutions, respectively. Thematic analysis identified emerging and crucial research areas. This review encompasses 45 articles investigating short- and long-term exposure to single pollutants (n = 18) and multi-air pollutants (n = 27). Particulate matter–PM2.5 (n = 12 of 16) and PM10 (n = 10 of 14), and NO2 (n = 8 of 14) demonstrated the most consistent associations with SAB followed by SO2 (n = 5 of 9) and O3 (n = 3 of 6), while CO (n = 4 of 6), PAH (n = 1 of 2), BC, and heavy metal (n = 1 of 1 each) showed inconsistent associations. This study reports considerable heterogeneity between studies concerning study design, air pollution exposure assessment, and outcome assessment. Studies of this nature present immense challenges and demand a standard protocol and a multi-disciplinary strategy involving scientists, epidemiologists, governments, and policymakers. Finally, systematic mapping and analysis performed in this study provide valuable insights into future research paths, offering a roadmap for further investigation.
期刊介绍：
Air Quality, Atmosphere, and Health is a multidisciplinary journal which, by its very name, illustrates the broad range of work it publishes and which focuses on atmospheric consequences of human activities and their implications for human and ecological health.
It offers research papers, critical literature reviews and commentaries, as well as special issues devoted to topical subjects or themes.
International in scope, the journal presents papers that inform and stimulate a global readership, as the topic addressed are global in their import. Consequently, we do not encourage submission of papers involving local data that relate to local problems. Unless they demonstrate wide applicability, these are better submitted to national or regional journals.
Air Quality, Atmosphere & Health addresses such topics as acid precipitation; airborne particulate matter; air quality monitoring and management; exposure assessment; risk assessment; indoor air quality; atmospheric chemistry; atmospheric modeling and prediction; air pollution climatology; climate change and air quality; air pollution measurement; atmospheric impact assessment; forest-fire emissions; atmospheric science; greenhouse gases; health and ecological effects; clean air technology; regional and global change and satellite measurements.
This journal benefits a diverse audience of researchers, public health officials and policy makers addressing problems that call for solutions based in evidence from atmospheric and exposure assessment scientists, epidemiologists, and risk assessors. Publication in the journal affords the opportunity to reach beyond defined disciplinary niches to this broader readership.
