Abstract
In this paper high-resolution continuum source atomic absorption
spectrometry (HRCS AAS) was used for the determination of metal concentrations in
Danube water collected in the river lower sector in SE Romania (Braila-Galati-Tulcea).
The evaluation of the water natural radioactivity was only performed in Galati sector
based on selected radiological parameters: gross alpha/beta activity and radionuclides
(210Po, 210Pb, natU, natTh and 226Ra) activity concentrations. The results indicate a
temporal and spatial variability of contaminant levels due to anthropogenic inputs and
seasonal conditions. For several heavy metals, the registered concentrations exceed the
legislated values, imposing a regular monitoring of water quality especially in the case
of using the water resource for human consumption, irrigation or aquaculture.
