摘要：

Information about heavy metal burden of children in Nigeria related to playground soils and classroom dusts is lacking. Playground soil, classroom dust, blood and spot urine samples (n = 253) were collected from 6 urban and 2 semi-rural public schools in Ibadan North-West, Nigeria. Samples were analysed for Pb, Cu, Zn, Fe and Mn. Mean blood Pb levels in urban area (male, 41.66 +/- 8.78 mu g/dl vs. female, 40.64 +/- 5.46 mu g/dl) were twice as high as those in semi-rural area (male, 19.71 +/- 3.73 mu g/dl vs. female, 20.65 +/- 2.26 mu g/dl). Concentrations of Pb, Cu, Zn, and Fe in soil and dust samples in the urban schools were between 2- to 4-fold greater than that of semi-rural schools. No correlation was observed between blood and dust metals. A positive correlation (r = 0.168, p = 0.008) was observed between blood Pb and playground soil Pb. Pb burden in the children might be from their schools' playgrounds and other yet unidentified sources. (C) 2016 Elsevier B.V. All rights reserved.
