This research reports the characteristic distribution and source apportionment of some heavy metals in dust of
Ikorodu area of Lagos State. The dust samples were collected randomly four times a month at ten different locations
in Ikorodu area. Dust samples were obtained by sweeping surface dust into plastic waste packer using plastic brush
and transferred into pre-labeled polythene bags. The samples were filtered through 75 μm stainless steel sieve,
weighed, digested with appropriate amount of HNO3 and H2O for 2 h. The concentrations of heavy metals were
analyzed using Atomic Absorption Spectrophotometer (AAS). Results showed that the percentage contribution of
each heavy metal at Ikorodu area were: Zn 79.4, Pb 14.8, Cu 0.9, Ni 4.9 and Cd 0.01. The most abundant heavy
metal was Zn 2869.70 mg/kg while the least was Cd 0.69 mg/kg. The most polluted site was
Residential Area 1 (993.674 mg/kg) while the least polluted was Industrial Area 3 (81.397 mg/kg). The major roads
(38.1%) had the highest concentration of heavy metal pollution while the agricultural area (5.7%) had the least
pollution. The sequence and distribution follow the pattern: Zn > Pb > Ni > Cu > Cd. The Principal Component
Analysis PCA showed that the major sources of heavy metals in Ikorodu dust are anthropogenic. Pearson
correlation analysis also showed that there was strong positive correlation (0.887) between the heavy metals. The
concentrations of Heavy metals Zn, Pb, Ni, Cu exceeded the recommended limits of the Federal Ministry of
Environment (FME), European communities (EC) and United Nations Environmental Programme (UNEP)
permissible levels for dust suggesting that the study area is polluted
