The present research is related to one of the basic component of the environment – waters with study area the Ogosta river catchment. It is based on the investigation of water samples collected during field research in the river monitoring area and laboratory analysis. The research is focused on the state of the pollution and quality of the water. The results can be used in the processes of environmental optimization and realization of the strategies for sustainable development in the region.
ABSTRACTHuman sapoviruses (SaVs) were quantified and characterized in an 18-month survey conducted along the Llobregat river catchment area in Spain. Sample types included freshwater, untreated and treated wastewater, and drinking water. All genogroups were recovered, and a seasonal distribution was observed. This is the first report of SaV quantification and genotyping in the environment outside Japan.
The results of studies of sea and river waters, soils of the territory adjacent to the Vanino transport and industrial hub are presented. Iron, manganese, copper and zinc have been identified as common priority pollutants of sea and river water. The quality of river waters of the Toki and Aya rivers, estimated by 14 hydrochemical indicators, is classified as "polluted". Local areas of peat-bog soil and brown soils belonging to the Toki river catchment area were identified as background areas in the studied territory.
