CONSIDERATIONS REGARDING Cu AND Ni DETERMINATION FROM MARINE ENVIRONMENTAL SAMPLES OF BLACK SEA USING FAAS

摘要

Our paper presents new results concerning Cu and Ni determination in marine biotope (sediment and water) and biocenosis (algae, crustaceans and fish) samples collected in 2005 and 2006 along the Romanian seacoast of Black Sea, between Mangalia and Varna Veche. The quantitative determinations were made by flame atomic absorption spectrometry (FAAS) technique. In all analyzed solid samples, the Cu concentration varied from 6.3650 to 20.6942 μg/g and Ni from 2.2831 to 82.7266 μg/g. In seawater samples, heavy metal concentrations were of μg/L levels.
