Determination of optimal sampling transects and pollutants for river sediments are essential and valuable. To determine if the concentration of some metals were highly correlated, correlations between heavy metals (As, Pb, Cd, Cr, Hg, Cu, Ni and Zn) were analyzed using statistic analysis software (SAS) based on monitoring data of heavy metals along the whole watercourse sediments of Dagu River. To...
Ion exchange (IE)-vapor generation (VG)-inductively coupled plasma (ICP)-mass spectrometry (MS) method has been employed to simultaneously determine trace amounts of As, Se, and Hg in acidic conditions. Before hydride generation, anion-exchange column was used to separate the analytes from the matrix. Effects of sample solution acidity, eluant conditions and concentrating time were investigated and...
