Analysis of PM₁₀ trends in open-pit mining: Assessing emission controls and WHO guideline compliance.

ABSTRACT: This study evaluated the concentrations, trends, and variability of PM₁₀ particulate matter in two Air Quality Monitoring Systems (CorpoGuajira's_AQMS and Cerrejón's_AQMS) in an open-pit coal mine in northeastern Colombia from 2010 to 2020. Additionally, different levels of emission controls were evaluated to achieve compliance with Colombian standards and international WHO guidelines. The results showed concentrations ranging from 24.14 μg/m³ to 46.46 μg/m³ in CorpoGuajira's_AQMS and 18.36 μg/m³ to 46.83 μg/m³ in Cerrejón's_AQMS. The concentrations of PM₁₀ at all the stations studied exceed the most recent annual guidelines of the World Health Organization (15 μg/m³); in contrast, the concentrations were below th
