Abstract
Assessment of Heavy Metals Pollution in Surface Sediments of a Tidal Creek in the Niger Delta, Nigeria
Highlights
In the Niger Delta, the problem of water and sediment pollution has been of concern to all stakeholders, following the rate and extent of degeneration of the environment and water bodies by human activities, from industrial and domestic sources (Daka and Moslen, 2013; Moslen and Miebaka, 2017)
The value of Cd concentration obtained in this study accords with the 0.1332 0.6229 mg/kg range recorded at Abonema shoreline (Ideriah et al, 2012) in the Niger Delta
The results indicated higher concentration of heavy metals (Zn>Cr>Pb>Cd) at stations within the Azuabie creek compared to the control creek (Okujagu)
Summary
In the Niger Delta, the problem of water and sediment pollution has been of concern to all stakeholders, following the rate and extent of degeneration of the environment and water bodies by human activities, from industrial and domestic sources (Daka and Moslen, 2013; Moslen and Miebaka, 2017). Heavy metals are often major constituents of wastes discharged into the aquatic system which deposit into the underlying sediment. Heavy metal pollution is one of the challenges of coastal water pollution due to human activities such as oil exploration and exploitation, construction and fabrication of marine boats, disposal of industrial and domestic wastes and sailing (Moslen and Miebaka, 2016, 2017). A metropolitan creek (Azuabie creek) in Port Harcourt city is one of such creeks that is prone to both industrial and domestic wastes discharges. Daka and Moslen (2013) had identified major waste inputs into the creek to include run-off from surrounding lands, animal wastes from a major abattoir, human/domestic waste from a high density settlements along
