| Abstract: | The levels of the metals Pb, Zn, Cu, Cd, Ni, Mn, and Fe accumulated in acrocarpous mosses within inhabited parts of villages and towns in the southwest region of Nigeria were determined, and then used for a classification of the area into relative pollution zones. Ibadan City was found to be the most polluted in the study area. Other zones of “low” and “medium” polluted villages and towns were identified. The zonations based on metal levels in these mosses were to some extent similar to that already obtained in a separate study of the same area with epiphytic forest mosses. The enrichment factors show that the gradients between zones of different pollution levels were higher in mosses within the inhabited sites. |
