Organic contamination has been discussed with regard to the different rivers of the world. Various organic pollutants, detected in water and the sediment of the rivers, have been ...

Current pollution status of Yangtze River and controlling measures

by Inderscience Publishers  (May 15, 2008)

The concentration of Persistent Organic Pollutants in Yangtze River in China is increasing steadily, especially in the downstream, where the drainage is often discharged into the water body without any treatment. In this study, the pollution status, trend of mainstream and Three Gorges area are analysed based on the statistical data of the water ...

A hydrodynamic water quality model for propagation of pollutants in rivers

by IWA Publishing  (Jul. 1, 2010)

Numerical modelling can be a useful tool to assess a receiving water body's quality state. Indeed, the use of mathematical models in river water quality management has become a common practice to show the cause-effect relationship between emissions and water body quality and to design as well as assess the effectiveness of mitigation measures. In ...

Identification of River Sections for Domestic Water Supply along the Yangtze River in Jiangsu Province, China

by Springer  (Mar. 5, 2005)

This paper presents major findings from a recent study aiming to systematically determine suitable river sections for local domestic water supply along the Yangtze River in Jiangsu Province, China. On the basis of analysis on the current riverbank utilization and bank stability, accessible and stable river sections in the region were selected. The ...

Monitoring and assessing heavy metals in topsoils as potential diffuse pollutants in the Pyeongchang River Basin, Korea

by IWA Publishing  (Jun. 1, 2010)

Topsoils, mainly from crop fields, orchards, forests, and barns around the Pyeongchang River, were collected to investigate their heavy metal concentrations. Pollution load index, ecological risk index, and enrichment factor were applied to assess levels of heavy metal contamination for topsoils. The concentrations of cadmium (Cd) (1.7 mg/kg) and ...

Water quality assessment of a polluted urban river

by Inderscience Publishers  (Oct. 7, 2013)

Urban rivers in Latin America are heavily impacted by human activities that affect their functions and services. This paper shows the results of a water quality assessment for the Reconquista River, the second most polluted urban river in Argentina. They allowed the identification of the main processes of transport of pollutants and the ...

Using a constructed wetland for non-point source pollution control and river water quality purification: a case study in Taiwan

by IWA Publishing  (May 1, 2010)

The Kaoping River Rail Bridge Constructed Wetland, which was commissioned in 2004, is one of the largest constructed wetlands in Taiwan. This multi-function wetland has been designed for the purposes of non-point source (NPS) pollutant removal, wastewater treatment, wildlife habitat, recreation, and education. The major influents of this wetland ...

Modelling of point and diffuse pollution: application of the Moneris model in the Ipojuca river basin, Pernambuco State, Brazil

by IWA Publishing  (Jul. 19, 2013)

Emissions of pollutants and nutrients are causing several problems in aquatic ecosystems, and in general an excess of nutrients, specifically nitrogen and phosphorus, is responsible for the eutrophication process in water bodies. In most developed countries, more attention is given to diffuse pollution because problems with point pollution have ...
