However, few studies have provided an overview of this area of research. The aim of this study was to look at the key trends in the research on prenatal exposure to air pollution. Data were retrieved from Web of Science, and the search was conducted based on the paper title, abstract, and keywords. The relevant literature searched was from 1994 to 2022, and 952 English documents were obtained. Of the total documents, 438 documents were included in the review and 83% (n = 365) of the documents were journal articles. Type of document, annual distribution of publications, and distribution of prenatal exposure by countries were extracted. Co-authorship and keywords co-occurrence analyses were also carried out. Of all the countries that published in this field, the United States of America. had the highest number of publications, followed by China. Among the different health and environmental disciplines, 62% (n = 273) of papers came from environmental science. There were limited collaborations among researchers from different countries and institutions. In conclusion, there should be more collaboration among the researchers in this field regarding institutions, countries, and disciplines.<\/jats:p>","DOI":"10.3390\/ijerph20043076","type":"journal-article","created":{"date-parts":[[2023,2,10]],"date-time":"2023-02-10T02:33:27Z","timestamp":1675996407000},"page":"3076","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Bibliometric Analysis of Literature on Prenatal Exposure to Air Pollution: 1994\u20132022"],"prefix":"10.3390","volume":"20","author":[{"given":"Bukola G.","family":"Olutola","sequence":"first","affiliation":[{"name":"School of Engineering, Science and Health, The Independent Institute of Education (IIEMSA), Roodepoort 1724, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paulina","family":"Phoobane","sequence":"additional","affiliation":[{"name":"School of Information Technology, The Independent Institute of Education (IIEMSA), Roodepoort 1724, South Africa"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sun, J., Zhou, Z., Huang, J., and Li, G.
