Pollution assessment of light rare earth metals in sediments of the Ogun River

This research was aimed at determining the concentrations of light earth metals in sediments of the Ogun River as well as their pollution and contamination status. Sediment samples collected using a graduated hand held sediment grab were stored in polythene bags and transported to the laboratory in an ice chested cooler. At the laboratory, the sediment samples were air dried, pulverized and sieved. Induced Couple Plasma...

Benthic macroinvertebrates in the biomonitoring of a Nigerian coastal water

Most coastal waters are exposed to high influx of pollutants due to the obvious elevated human activities. In order to adequately evaluate the extent of toxicity of contaminants in the ecosystem, and their synergistic effects, marine ecologists prefer biomonitoring to chemical approach. The benthic macroinvertebrates, due to their sedentary mode of life and residence at the sediment-water microcosm, are regarded as the...
