Particulate matter dispersion patterns near Klotok landfill site

This study aims to investigate the spatial distribution of particulate matter (PM) emissions around the Klotok Landfill Site in Kediri, Indonesia. Direct measurements of Total Suspended Particulates (TSP), PM10, and PM2.5 were conducted using air samplers at various locations surrounding the landfill. The collected data were then processed and visualized using Surfer software to generate spatial distribution maps. The measured concentrations did not exceed the ambient air quality standards set by Regulation No. 22 of 2021, the values were close to the regulatory limits. The concentration near the weighbridge area with high truck traffic and in the eastern region is likely influenced by prevailing winds. The generated maps provide valuable insights into the extent and patterns of PM dispersion, which can be utilized for future management and mitigation strategies to minimize the health risks associated with particulate matter exposure near the landfill.
