Elucidation of the Physicochemical Characteristics and Health Risk Assessment of Heavy Metals in the Sediment of Ajoki River, Ikpoba-Okha Local Government Area in Edo State, Nigeria

Sediments play a critical role in aquatic pollution studies, functioning both as sinks and potential secondary sources of contaminants. Over time, pollutants become embedded within sediment layers, serving as historical records of environmental pollution. This study assessed the physicochemical properties, pollutant levels and associated health risks in sediment from the Ajoki River, located in Ikpoba-Okha Local Government Area, Edo State, Nigeria. Samples were collected over a 12-month period, covering both the wet (May-October 2022) and dry (November 2022–April 2023) seasons.

Distribution and Risk of Metals in Soils of Refuse Dumpsites in Some Urban Towns in Delta State, Nigeria

Refuse dumpsites often contain materials capable of polluting surrounding soils. In this study, the spatial distribution of metals in soils of refuse dumpsites in three urban towns (Ughelli, Sapele, Orhuwhorun) in Delta State, Nigeria were examined. Soil samples were collected from three dumpsites in the aforementioned towns at depths 0-15 cm, 15-30 cm and 30-45 cm, respectively.
