ASSESSMENT OF RIVER WATER QUALITY IN CENTRAL AND EASTERN PARTS OF ROMANIA USING ATOMIC GF5AND OPTICAL METHODS
Journal Title: Journal of Science And Arts - Year 2010, Vol 12, Issue 1
Abstract
The main objective of this paper is to assess the water quality of some rivers from Brasov, Braila and Galati counties (Timis, Danube and Prut) using atomic and optical methods: Atomic Absorption Spectrometry (AAS), UV-VIS Spectrometry and Turbidimetry. The concentrations of Cd, Co, Cr, Cu, Fe, Ni, Pb and Zn in the water samples were determined by AAS technique using the AVANTA GBC spectrometer from Valahia University of Targoviste, with flame and hollow cathode lamps (HCL). The UV-VIS spectrometric and turbidimetric determinations were carried out at Physics Department, “Dunarea de Jos” University of Galati, using WTW - TURB 430 IRIR/T portable turbidimeter and Perkin Elmer Lambda 35 UV-VIS Spectrometer. The river water turbidity and absorbencies are correlated with the concentrations of heavy elements detected in the analyzed water samples. This study is part of a partnership project funded by National Plan of Research, Developing and Innovation, of implementation of high precision and sensibility methods for the biomonitoring of the environmental pollution in South, South-East and Central regions of Romania (Project 72-172/2008).

NANOMATERIALS PHYSICAL PROPERTIES SIMULATION AND MODELING APPLICATIONS
Modeling of nanomaterials requires realistic description of the system across various length and time scales. In order to illustrate how atomistic modeling is being used to determine the structure, physical, and chemical...
SOME ASPECTS REGARDING NOISE EXPOSURE DOSE MONITORING FOR WORKING PERSONNEL
There are many situations where there is the need to accurately assess the risk of exposure to high noise levels and to monitor any employees who are exposed to potentially damaging noise. Framed both on health assurance...
INVESTIGATION OF PROJECTILE MOTION ON THE INCLINED PLANE
In this paper the equations and relations of projectile motion on inclined planes are concluded from concepts such as angular momentum and torque. In addition to describing this concept explicitly, we have tried to clari...
