Roadside Sand Deposits as Toxic Metals' Receptacles along three Major Roads in Port Harcourt Metropolis, Nigeria
Authors(2) :-Christian Mathew, K. J. Orie
Roadside sand deposits are common sights along all roads in city centres like Port Harcourt in Nigeria. Studies have shown that, these sand deposits are receptacles for heavy metals emitted from varying sources. This study therefore, investigated the concentrations of four toxic metals Cadmium (Cd), Chromium (Cr), Lead (Pb) and Nickel (Ni) in roadside sand deposits. Three research questions were addressed using results of analyses of data obtained. Samples were collected along three major busy roads in Port Harcourt City using atomic absorption spectrophotometer, AAS. The results show that all four toxic metals except Cd were significantly available in the sand deposits with mean concentrations as follows: Cadmium 0.00 mg/kg, Chromium 2.81±2.21 mg/kg, Lead 1.09±0.70 mg/kg and Nickel 2.41±1.07 mg/kg. The detected concentrations were found to be high in relation to FEPA and WHO standards. The results also show that the mean concentrations are significantly different among the metals investigated but opposite is the case along the roads investigated. Therefore, the attention of environmental regulatory agencies is hereby drawn to this potential reservoir of environmental toxicants. The unsuspecting public, business operators, and others that depend on these roads for their livelihood are also enjoined to appreciate the dangers on these roads
