Assessment of heavy metals bioaccumulation by Eleusine indica from refuse dumpsites in Kaduna Metropolis, Nigeria
The levels of bioaccumulation of heavy metals (Pb, Cr, Zn, Cd, Mn and Cu) in Eleusine indica and waste soil samples from ten refuse dumpsites located in Kaduna Metropolis was assessed using atomic absorption spectrophotometer (AAS). The soil pH, electrical conductivity (EC), organic matter (OM) and available phosphorus (AP) were also determined. The results of analysis of the waste soils from the...
Spatiotemporal assessment of metal concentration in fish and periwinkles in selected locations of Lagos Lagoon, Nigeria
Fish and periwinkles, from nine locations in the Lagos Lagoon, were processed and analysed for the presence of heavy metals (chromium Cr, manganese Mn, iron Fe, nickel Ni, copper Cu, zinc Zn, cadmium Cd and lead Pb) during the dry and wet seasons. Results showed that significant differences existed in the levels of metals in periwinkle and fish caught from the different locations while the influence...
