Abstract

Source apportionment of particulate matter (PM) on the premises of Obafemi Awolowo University Teaching Hospital, IleIfe,Nigeria was studied to assess the contribution of traffic to the PM on the premises of the facility. The coarse particulate fraction was the most dominant in the three sampling sites especially at the Phase 1 and Auditorium sites that were identified to be heavy and medium traffic areas with an average PM_2.5/PM₁₀ ratio of between 0.54:1 and 0.38:1. Six sources were identified for each size fraction of PM_2.5 and PM_2.5-10, including biomass burning, fuel combustion, soil, and sea salt plus vehicular emission for PM_2.5 while soil plus biomass burning, and sea salt plus vehicular emissions. This is an abstract of a paper presented at the 108th AWMA Annual Conference and Exhibition (Raleigh, NC 6/22-25/2015).
