Two open wells and a stream were monitored during a three year investigation. A total of 25 and 31 species of zooplankton were found in open wells and 11 and 12 taxa of macrozoobenthos at two sites of stream Sugavac. The saprobity index (S) was used to evaluate the water quality of these four sites. Statistical analysis showed that site S2 was the most polluted, with Oligochaeta and Chironomidae larvae dominating. Overall, beta mesosaprobic organisms have been prevailing at all four sites indicating that the water was polluted at moderate levels. All analyzed fish gills showed predominantly normal structure. Identified histopathological changes of gill structure indicated mild and reparable alterations. T... |
