Abstract

In this study, indoor settled dust samples were collected from twenty one offices within the seven College buildings of the University of Agriculture Makurdi, Nigeria. The dust samples were analysed for the concentrations of Cadmium (Cd), Chromium (Cr) and Lead (Pb). The results of the analyses show toxic metals concentrations in the order of Cd < Cr
