EVALUATION OF METALS AND PAH (POLYCYCLIC AROMATIC HYDROCARBONS) CONTAMINATION LEVEL FROM CLUJ-NAPOCA SOIL
Abstract
Four soil samples (3 from the city exits and one from the Central Park) from Cluj-Napoca were analyzed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and High Performance Liquid Chromatography (HPLC) techniques to establish their level of contamination with metals and polycyclic aromatic hydrocarbons (PAH). The results for metal analysis obtained by ICP-MS showed a contamination of all investigated samples with Ni and As above the normal limits foreseen by Romanian legislation. Also one of the sample presented contamination with Mn above the normal limits. The results for PAH obtained by HPLC show a small contamination with naphthalene, phenanthrene and total PAH in the west exit of Cluj-Napoca. These results suggest that a further investigation of the soil from Cluj-Napoca it is necessary before drawing final conclusions.The papers published in the journal are licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License, which permits unrestricted, non-commercial use, distribution and reproduction in any medium, provided the work is properly cited.
