Contamination levels, health risks and source apportionment of potentially toxic elements in road dusts of a densely populated African City
ET Odediran, JA Adeniran, RO Yusuf… - Environmental …, 2021 - Elsevier
Potentially toxic elements (PTEs) are increasingly becoming a health and ecological
concern, especially in cities with heavy traffic from rapid urbanization and industrialization.
Contamination levels, sources and health risks of ten PTEs (Fe, Pb, Zn, As, Co, Cr, Cu, Cd,
Mn and Ni) in twenty-five traffic hotspots (sites) of Ibadan-a densely populated African city
were investigated during the rainy and dry seasons. The possible sources of PTEs were
identified and quantified by combining positive matrix factorization (PMF) with existing and …
