Heavy metals in sediments from River Ngada, Maiduguri Metropolis, Borno State, Nigeria

  The objective of this research was to determine the degree of heavy metal contamination in River Ngada and the extent to which the sediment quality of the river had deteriorated. In this study, metals such as Cu, Zn, Co, Mn, Mg, Fe, Cr, Cd As, Ni and Pb in the sediments were determined using Perkin-Elmer Analyst 300 Atomic Absorption Spectrophotometer. The extent of sediment quality deterioration was observed...

Modification and validation of a microwave-assisted digestion method for subsequent ICP-MS determination of selected heavy metals in sediment and fish samples in Agusan River, Philippines

  This study investigated, validated, and applied the optimum conditions for a modified microwave-assisted digestion method for subsequent ICP-MS determination of mercury, cadmium, and lead in two matrices relevant to water quality, that is, sediment and fish. Three different combinations of power, pressure, and time conditions for microwave-assisted digestion were tested, using two certified reference...
