Geochemical sediment of the tropical Pinang River, Malaysia was carried out with the aim at documenting elemental concentrations and pollution level assessment. Concentration of selected heavy metals (Cu, Cd, Cr, Pb, Zn and Mn), rare earth elements, TOC and grain size distribution of sediments were determined at 100 m sampling interval along the river. Sediment size showed a positive correlatio...
Selected heavy metals (Cr, Cu, Ni, Pb and Zn) in surface sediments from the coastal Shandong Peninsula (Yellow Sea) have been determined to evaluate the spatial distribution and potential ecological risk. Results showed that heavy metal concentrations in the sediments generally met the criteria of China Marine Sediment Quality. However, both the enrichment factor (EF) and geoaccumulation index ...
Sungai merupakan tempat yang paling baik untuk melakukan pengamatan dari pencemaran logam berat pada sedimen terkandung didalamnya. Kegiatan industri daerah aliran sungai melibatkan penggunaan seperti tekstil, pelapisaan logam, cat/tinta warna, percetakan, bahan agrokimia. Penggunaan Geoaccumulation index (Ige) salah satu metode mengukur besaran kadar Sedimen dan tingkat dalam sedimen. Sehingga...
background: this study aimed to evaluate the pollution levels of surface water with heavy metals including pb, cd and cr in gheshlagh river, western iran. methods: water and sediment were sampled in five monitoring stations with three replicates in time along the river. the concentration of cr, pb and cd in both water and sediment samples were measured with graphite furnace atomic absorption sp...
