Abstract

Mosses plants have proven to be excellent indicators of atmospheric pollution, as they reflect metals concentration gradient and sources of deposition. The major objective of this study is to investigate the concentrations of some metals (Zn, Pb, Cd, Ni and Cu) content in moss plant (Polytrichum commune) collected at different microenvironments within Yaba College of Technology Campus, Lagos state, Southwestern – Nigeria. The samples of the plant were collected randomly between September and November, 2016 at 10 different locations at the Campus between 2 - 2.5 metres high from unplastered buildings in Lagos state. The samples were properly cleaned from all the debris, weighed and digested with a mixture of HN03 and H2O2 for 35 min. The concentrations of heavy metals were analyzed by Atomic Absorption Spectrophotometer (AAS) Perkin Elmer AA 200. Results show that the average concentrations of the heavy metals at Yaba College of Technology Campus were Zn 12.711µg/g, Pb 1.174 µg/g, Cu 9.095 µg/g, Ni 3.626 µg/g, and Cd 0.086 µg/g. The most polluted site is Students affairs unit (6.532 µg/g) while the least polluted is Bakassi hostel (1.031 µg/g). The levels of some of the heavy metals were present in concentrations greater than WHO threshold limiting values.
