ICP-MS DETERMINATIONS OF HEAVY METALS IN SURFACE WATERS FROM TRANSYLVANIA

This study proposed to investigate the quality of surface waters used as raw water source by Water Treatment Plants which provide drinking water for a large number of inhabitants. Studied area includes two districts from Transylvania, namely Cluj and Salaj. A wide number of metals were identified in all water samples; usually in most water samples the amounts or such toxic metals were between the ranges of few mu g/l. Inductively coupled plasma mass spectrometry (ICP-MS) is an analytical technique used for elemental determinations; the Perkin Elmer Elan DRC(e) ICP-MS instrument was used to perform water samples analysis.
