This paper describes the concentration of selected heavy metals (Co, Cu, Ni, Pb, and Zn) in the Mamut river sediments and evaluate the degree of contamination of the river polluted by a disused copper mine. Based on the analytical results, copper showed the highest concentration in most of the river samples. A comparison with Interim Canadian Sediment Quality Guidelines (ICSQG) and Germany Sedi...

Heavy metal pollution is of particular concern as they have deleterious effects on biota through mobilization and accumulation in various trophic levels. The present study mainly focused on the water pollution by heavy metals in Cochin estuary and two adjoining rivers. The methods include seasonal collection of surface water from the study area and their subsequent heavy metal analysis. The stu...

This study aimed to identify specific river sources of fecal contamination by applying pulsed-field gel electrophoresis (PFGE) to environmental water samples from a recreational beach in Japan. The genotypes of all Enterococcus faecium and Enterococcus faecalis strains used as indicators of fecal pollution on the recreational beach and rivers were analyzed by PFGE, and the PFGE profiles of the ...

This paper presents a multi-criteria based tool for assessing the relative impact of diffuse-source pollution to the Great Barrier Reef (GBR) from the river basins draining into the GBR lagoon. The assessment integrates biophysical and ecological data of water quality and pollutant concentrations with socio-economic information pertaining to non-point source pollution and (potential) pollutant ...

Himalayan Journal of Sociology & Anthropology-Vol. III Pollution of Seti River in Pokhara An Anthropological Perspective Amrit Kumar Bhandari Abstract Seti River is one of important components of the ecology of Pokhara so it holds a great significance for maintaining ecological balance and fulfilling different types of needs of people here. But only a few people are aware of its real value whil...

Understanding the primary effects of anthropogenic activities and natural factors on river water quality is important in the study and efficient management of water resources. In this study, analysis of Variance (ANOVA), Principal component analysis (PCA), Pearson correlations, Multiple regression analysis (MRA) and Redundancy analysis (RDA) were applied as an integrated approach in a GIS envir...

Under rapid urban sprawl in Northeast China, land conversions are not only encroaching on the quantity of cultivated lands, but also posing a great threat to black soil conservation and food security. This study's aim is to explore the spatial relationship between comprehensive cultivated soil heavy metal pollution and peri-urban land use patterns in the black soil region. We applied spatial la...

Water is a valued natural resource for the existence of all living organisms. Management of the quality of this precious resource is, therefore, of special importance. In this study river water samples were collected and analysed for physicochemical and bacteriological evaluation of pollution in the Unity Road stream segment of Asa River in Ilorin, Nigeria. Juvenile samples of Clarias gariepinu...

Material flow analysis (MFA) is a promising tool for river water quality management. Based on orders-ofmagnitude estimations, the approach provides an overview of pollution problems and their dimensions in a river system, allowing to identify key sources and pathways of pollution, and to evaluate mitigation priorities. The current study aims at investigating MFA to assess river water quality pr...
