Monitoring of priority hazardous substances from an industrial platform area

Abstract

This paper aims to establish the degree of pollution with priority hazardous substances in soil, water and sediments on the complex industrial platform Râmnicu Valcea. The studied area is a section of 20 km long in the lower basin of the Olt River. For the study were collected soil samples inside the platform, in the areas where they used priority hazardous substances and water and sediment samples from the Olt River and Govora River (tributary of the Olt River). The following priority hazardous substances have been determined: copper, nickel, lead, mercury, cadmium, zinc, chromium, cobalt, manganese, 1,2- dichloroethane, 1,1,2- trichlorethylene, perchlorethylene and 1,2,4- trichlorobenzene. The heavy metal content has been determined by inductively coupled plasma-mass spectrometry), while organochlorinated substances by chromatography coupled with mass spectrometry. These values are analyzed by comparing with admitted limits imposed by the regulations in force and the possible origin of pollution sources is discussed.
