Regulatory measures, such as emission controls, stricter air quality standards, and the promotion of cleaner technologies, are crucial in reducing PM emissions at the source. XRF analysis is a powerful tool for characterizing PM filters for air quality monitoring purposes. It provides valuable insights into the elemental composition of particulate matter, assists in source identification, facilitates real-time analysis, and supports quantitative assessment. By utilizing XRF techniques, environmental monitoring programs can better understand the bad impacts of PM on human health and the environment can be mitigated to support the aim of the United Nations Sustainable Development Goals (n. . Table provides a summary of relevant literature reporting the use of XRF based techniques for elemental analysis of PM loaded substrates, including details of sample preparation methods, XRF configuration, quantification approach, and elements analysed.
