Abstract
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.
