Determining the Concentration of Some Heavy Metals in Olt River.The Impact of the Heavy Metals from the Waste Waters from Rm.Valcea Chemical Plant over Natural Emissary River Olt

摘要

The pollution of water surfaces with heavy metals often has disastrous effects on environment.That is why the determination of heavy metals'concentrations at levels of ppm or ppb is strictly necessary.This paper presents a method for the determination of these components'(Ni,Cr,Zn,Fe,Cu)distribution on the Olt river course-their impact on the Olt river-as a result of the evacuation of waste water with toxic heavy metals from Rm.Valcea Chemical Platfom.The most toxic heavy metals determined were.Ni,Cr,Zn,Fe,Cu,.The concentration of these metals was determined by atomic absorption spectrometry method(AAS)using an analyzer type A ANALYST 700.
