Abstract Fine particulate matter (PM2.5) samples were collected simultaneously at urban sites in Lagos (ULG site) and in Hong Kong (TC site) for four consecutive weeks in July and August 2017, in order to investigate the potential to apply successful pollution control measures from Hong Kong to Lagos. To compare chemical characteristics and sources of PM2.5 in these two regions, organic carbon (OC), elemental carbon (EC), water soluble ions (WSIs), and elements were analyzed for the first time. It was found that total carbon and elements were much more abundant (p
