Description
Mauricio A. Correa-Ochoa and co-authors present a 2026 air quality study from Medellín, Colombia, a city set in a narrow Andean valley where pollution collects. The team measured what fine particles in the air are made of and where they come from.
They collected 112 samples between March 2019 and March 2020 and tested them for metals, ions, and carbon-based material. Statistical analysis separated five sources, led by resuspended mineral dust and secondary aerosols. Air mass tracking and satellite fire data showed smoke drifting in from the Magdalena, Orinoco, and Amazon basins during dry periods. The authors argue that local traffic controls must be paired with responses to regional burning episodes.
