dc.description.abstractThe present study evaluate the relationship between the level of some metals in the particulate dust, and blood, urine, nails and hair of human exposed to metals contamination due to the dumpsites located within their residential areas. The concentrations of Zn, Pb Cu Cd and Hg are determined by Varian AA240FS Atomic Absorption Spectrometry. The results obtained revealed differences significant at p < 0.05 in levels of metals in dust samples across the seasons. Overall, the order of the bioavailability of these metals in the near the dumpsites followed the pattern: Cd > Zn > Pb > Hg > Cu; Hg> Zu. Cd> Cu> Pb and Zn> Hg> Cd > Pb > Cu for the dust nails and hair samples. The trend followed for the average concentrations of these metals across the sites followed the same pattern in both the urine and blood samples. Hg > Zn > Pb > Cd > Cu. The bioavailability of these metals some 300m away from the dumpsites revealed different distribution patterns Zn> Hg> Cd> Pb> Cu; Hg> Pb> Zn> Cu> Cd; Hg> Zn> Cd>Cu> Pb; ITg> Zn> Cd> Pb> Cu and Zn Cd> Cd> Pb=Hg for the dust Urine, blood, nails and hair samples respectively. The concentrations of the metals in the tissues of the residents in the dumpsites areas were higher than those recorded 300m away from the dumpsites (control sites). Moreover, one of the toxic metals, mercury was not even recorded in the tissues of the control site residents in the wet season, a clear indication of the level of pollution caused by the dumpsites.en_US
