Abstract
The aim of this work was to examine the impact of urban wastewaters on the
water quality of the Danube River in Serbia. Samples of water and sediments
for microbiological analysis and genotoxicity monitoring were collected from
6 sites during spring and/or autumn 2010. Sanitary analysis, i.e. enumeration
of total and fecal coliforms and intestinal enterococci, indicated moderate
to critical fecal contamination, while organic load assessment (oligotroph to
heterotroph ratio, index of phosphatase activity) revealed the category of
moderately polluted water. Mercury-resistant bacteria were detected in all
water samples, with high numbers at locations positioned downstream of
Belgrade. There was no correlation of the microbiological parameters of the
sediment and water samples. Genotoxicity monitoring, performed by the comet
assay on hemocytes of mussels Sinanodonta woodiana, indicated a significant
increase of DNA damage in mussels collected from the studied sites compared
with the control group.
