Rare earth element (REE) composition of atmospheric dust has recently been used to trace potential sources of dust pollution. The present study aimed to determine the sources of atmospheric pollution in the study area using REE patterns and determine their level of pollution. Twenty-five (25) atmospheric dust samples were collected in the study area, with five samples each from an industrial area, traffic area, dumpsite area, residential area and remote area in Ibadan, southwestern Nigeria. In addition, five (5) topsoil and tw
