The concentration of respirable dust at seven sampling stations in Jos metropolitan area, was measured weekly for three consecutive months (October 2012 to December 2012). Characterization of the dust particles shows that the concentration of fine dust (<2.5 µm) ranged from 55.0 -124.9 µg/m 3 while the coarse dust (2.5 -10 µm) varied from 20.0 -124.4 µg/m 3 . FAAS analysis of the respirable dust shows that the concentrations of heavy metals ranged from 0.121 -0.832 mg/kg Pb, 0.019 -0.111 mg/kgdoi:10.4236/ojap.2014.31002 fatcat:myd3osivlncklazdxte6sq5gre
