Editorial statement
While it has been established for decades that particulate matter, especially the PM2.5 fraction, can be quantitatively linked to a variety of negative health outcomes from both long- and short-term exposure, our ability to conclusively link this to specific particle components or types has proved stubbornly elusive. If particular sources or chemical components were found to be the driving factors, these could lead to more effective interventions and regulations. Because of recent advances in our observational capabilities and fundamental understanding of particle composition and toxicity, this opinion piece argues that we are at a pivotal moment in this ongoing area of study, and summarises some recent advances in this area.

Short summary
This opinion paper explores how advances in aerosol science inform our understanding of the health impacts of outdoor particulate pollution. We advocate for a shift in the way we target PM pollution, focusing on the most harmful anthropogenic emissions. We highlight key observations, modelling developments, and emission measurements needed to achieve this shift.
