The systematic review across all specified databases (Google Scholar, Web of Science, Science Direct, Scopus, and OpenGrey) was conducted between 1 October 2023 and 31 January 2024 to identify all studies reporting the concentration of microplastics across the world’s five oceans. All the keywords were interchangeably paired with the Boolean connectors and the truncations to identify studies between 1 January 2010 and 31 December 2023. The comprehensive literature search yielded a total of 7870 pertinent studies retrieved from five distinct databases, as follows: 951 in Google Scholar, 6541 in Web of Science, 183 in Science Direct, 185 in Scopus and 10 studies in OpenGrey. From each database, the studies were exported to Endnote 20 and Covidence software for further data management.
