Abstract:

The concentration of selected metals including Li, Co, Ni, Ag and Au were determined in surface water of Ogbunabali creek, Port Harcourt, Rivers State, Nigeria, impacted by disposal of electronic wastes. Three (3) water samples (A, B and C) were collected into plastic sampling bottles along the Ogbunabali creek and transported to the laboratory for analysis. The water samples were digested using HNO3 and HCl and quantified using flame atomic absorption spectrophotometry. The concentration (in mgL-1) of metals obtained from the analysis were Li: 0.007, 0.0015 and 0.0009; Co: 1.6750, 1.8130 and 1.6620; Ni: 0.7564, 0.2480 and 0.8706; Ag: 0.0417, 0.0325 and 0.0398; and Au: 0.0510, 0.0381 and 0.0399 for samples A, B and C respectively. Some of the heavy metals (Li, Co, Ni, Ag and Au) analyzed were relatively high and above the WHO set limit. The analyzed metals could exert negative effects on human health and the environment. It is therefore concluded that deposition of e-wastes on landfill close to the creek leach the heavy metals used in producing them into the environment.
