Concentrations of elements in sediments were measured using an inductively coupled plasma-optical emission spectrometer (ICP-OES; Agilent 720ES, Darmstadt, Germany) with axial torch and echelle optic configuration, Charge Couple Device (CCD) detection system and full wavelength coverage from 167 nm to 785 nm. Operating parameters were as follows: Incident power was 1.20 kW, Plasma gas and auxiliary gas flow were 16.5 and 1.5 L•min -1 , respectively. Sample uptake and test time per repetition were 45 and 30 s, respectively. Although more elements were measured, the considerations in this work were limited to the elements As, Cd, Cr, Cu, Ni, Pb, S, and, Zn, as these were deemed most suitable for evaluating any industrial impact.
