Title: | The mobility study of some priority hazardous substances in the sediments of rivers polluted by industrial human activities | Authors: | Kim, Lidia | Keywords: | Heavy metals;Bioavailability;Extraction method;Sediment;Water;Polution;Mobile metals | Issue Date: | 2014 | Abstract: | The project concerns to establishment some optimal methods of extraction of mobile metal forms of Cd, As, Cu, Ni, Pb in sediments associated Certej mining area, Baiaga River. Within this project were elaborated and developed methods of extraction of mobile forms of metal compounds by mass spectrometry with inductively coupled plasma (ICP-MS) and was evaluated the bioavailability of metals to pass from sediments into surface water. The results obtained in the seven sampling campaigns and spatio-temporal evolution of total and mobile heavy metals emphasize a high contamination of sediment with As, Cd and Pb, of which Cd and As are present mostly in a bioavailable form, inducing a high degree of pollution on the aquatic environment by passing these metals from sediments into surface water. |
