Abstract

The heavy metal contents of solid municipal wastes produced at various (sites) in Lagos (1), Ibadan (1), Ogbomoso (2), Ilorin (1), Osogbo (1), Ile-Ife (1), Ejigbo (2), Iwo (1) and Oyo (1) were measured. The solid municipal wastes produced in high density towns showed higher levels of iron, zinc, and cadmium (P <0.05). There is no significant difference (P <0.05) between the mean concentrations of other metals in the high and low density towns. The inter-element correlation and significance of some heavy metal levels in Nigerian environment are discussed.
