Nondestructive analysis of dumpsite soil and vegetable for elemental composition

In this study, dumpsite soils and vegetables were analyzed for total elemental composition using a 5SDH Tandem Pelletron accelerator available at Centre for Energy Research and Development, Obafemi Awolowo University Ile-Ife. The results at a 2.5 MeV energy revealed the presence of elements: Cu, Cr, Ni,Al, Si, P, S,Cl, K, Ca, Ti, Mn, Fe, Zn, Rb, Sr, Y, Zr  and Pb in the dump site soil, with the exception of...

Heavy metal bioaccumulation and oxidative stress in Austroaeschna inermis (Dragon fly) of the Lagos Urban ecosystem

Urban ecosystems are often characterized by the receipt of pollutants, especially heavy metals from diverse anthropogenic activities. To better understand the distribution of heavy metals (Cd, Cu, Pb, Mn and Zn), Austroaeschna inermis from five different sites (Unilag, Mile 12, Olushosun Dump site, Imoshe and Badagry) in Lagos, sediments from the respective sites were assessed. This was followed by assessment of lipid...
