Geochemical distribution and ecological risk level of inorganic pollutant of River Ethiope sediment

Abstract

This study assessed heavy metals concentration of River Ethiope, Delta State. The sediments was geochemically partitioned and analyzed using atomic absorption spectrophotometer in order to determined the concentration level and heavy fractions in Ethiope river sediments. Geochemically fraction results proved that 50% of the assessed metals were associated with Fe-Mn oxide fraction.

Environmental risk factor revealed that cu will posed a greater potential threat to aquatic organisms among the investigated metals. It is therefore, recommended that agencies of government such as federal ministry of environment should routinely monitored Ethiope river sediments in order to ensure reduction in the level of contamination by heavy metals.
