Bibliometric review reveals particulate matter disparities across global regions, highlighting the need for artificial intelligence and stricter standards.
Key Points
To assess global trends, major emission sources, health impacts, and mitigation strategies for particulate matter air pollution.
Conducted a systematic review and bibliometric analysis of 427 documents published between 1993 and 2025 retrieved from the Web of Science database.
Analyzed thematic evolution, collaboration networks, and publication patterns using VOSviewer and the Biblioshiny package in R Studio.
Scholarly output on particulate matter has increased substantially, led primarily by institutions in China, India, and the United States.
South and East Asian regions report the highest particulate matter concentrations due to industrial emissions, vehicle exhaust, and biomass burning, whereas the EU and USA maintain lower levels under strict regulations.
Critical monitoring deficiencies persist in remote regions, underscoring the necessity of low-cost sensors, artificial intelligence tools, and alignment with World Health Organization standards.
