Chemical Characterization of PM1-2.5 and its Associations with PM1, PM2.5-10 and Meteorology in Urban and Suburban Environments

Abstract

This study investigated the PM1-2.5 (the intermodal fraction of particulate matter) representing the transition area between the fine and coarse size ranges. Due to this characteristic, PM1-2.5 may contain particles from both modes.

The aim of this work was to examine the associations between PM1-2.5 and the coarse (PM2.5-10)/fine (PM1) fraction under different meteorological conditions at various sites in the Czech Republic during winter and summer.
