Spectrometric Methods Used to Determine Heavy Metals and Total Cyanides in Accidental Polluted Soils

Abstract

The study presents the level of soil pollution in the area adjacentto three sedimentation ponds as a result of an environmental accidentin Baia Mare region of Romania. Soil samples from various sites havebeen collected and analyzed to det. the concn. of heavy metals (Cu,Pb, Zn) and total cyanides. The anal. methods used were ICP-AES forheavy metals and the colorimetry for total cyanides. The accuracyof both methods is detd. subject to the reproducibility of the results.The concns. detd. indicate deep pollution of the local ecosystem.[on SciFinder(R)]
