Abstract

Particulate Matter (PM) samples were collected using deposition gauges (0.2m x 0,15m) at the selected industrial areas within Ikeja LGA during the period of May to June 2015 for the wet season and the period of December 2015 over January 2016 for the dry season respectively. The collected samples were filtered and dried for the wet season while that of the dry season was rinsed with distilled water and then subjected to the same process as of the wet season. The Deposition Flux (DF) of the measured PM ranged from 38.01 – 197.11 g/m2.month in the wet season and ranged from 18.14 – 74.08 g/m2.month in the dry season. The DFs for Lagos State University Epe (LSUE) ranged from 57.65-62.96 g/m2.month and 42.39-51.06 g/m2.month in the wet and dry seasons, respectively. The Iron elemental ratio ranged from 0.002-3.885 in the wet and dry seasons. The Enrichment Factor ranged from 0.00- 8940.93 on both seasons. PM samples collected exceeded the United States Environmental Protection Agency (USEPA), World Health Organization (WHO) and reveals anthropogenic sources
