non-point pollution are an important factor in determining water quality and eutrophication of fresh water. the principle causes of this issue is high concentrations of nutrients in the water especially nitrogen and phosphorus. change of land use particularly affected on water nitrate load. therefore, understanding the correlations between land use and nitrate pollutant is a priority in order t...

Results of radar monitoring of the sea surface in the Russian sector of the Black Sea coastal zone are presented. The attention was focused on the detection of oil pollution as well as biogenic and anthropogenic surfactant films. The basic data were high resolution radar images obtained by synthetic aperture radars (SAR) on board Envisat and ERS-2 satellites of the European Space Agency. Spatia...

In this study, movement of phosphorus pollution which is leachate to groundwater was investigated in Seri Petalling Landfill. Visual MODFLOW was used to predict subsurface and surface migration of pollution within 10 years. The results of sample analysing of phosphorus has shown its concentration in place of landflill was 2.38 mg/l since the National Water Quality Standard for Malaysia defined ...

Water quality assessment at the watershed scale requires not only an investigation of water pollution and the recognition of main pollution factors, but also the identification of polluted risky regions resulted in polluted surrounding river sections. To realize this objective, we collected water samplings from 67 sampling sites in the Honghe River watershed of China with Grid GIS method to ana...

There is rapidly growing interest in the use of market-based (MB) instruments in environmental policy. The papers in this session discuss three relatively new areas for such policies: groundwater contamination, nonpoint source surface-water pollution and carbon sequestration. The papers point out the potential for MB policies in these areas, but significant challenges remain. This comment highl...

Azaarenes belong to the newly identified classes of anthropogenic pollutants. To our knowledge, this study presents the first result of pollution history of azaarenes and their controlling factors in estuary. To understand the transport mechanisms, surface sediment samples were collected from 18 sites of the Danshuei River during the summer and the winter of 2005. The highest concentrations of ...

a general overview on the prospective of various oxidation and combined processes in the treatment of tannery industry effluent are reported. various oxidation and combined processes such as uv/h2o2/hypochlorites, fenton and electro-oxidation, photo-chemical, photo-catalytic, electro-catalytic oxidation, wet air oxidation, ozonation, biological followed by ozone/uv/ h2o2, coagulation or ele...

Hydrological and pollutant fate models have long been developed for research purposes. Today, they find an application in integrated watershed management, as decision support systems (DSS). GIBSI is such a DSS designed to assist stakeholders in watershed management. It includes a watershed database coupled to a GIS and accessible through a user-friendly interface, as well as modelling tools tha...

Surfactants are amphipathic compounds having both lipophilic and hydrophilic structural moieties in its molecule. They are mostly produced on microbial surfaces or excreted extracellular hydrophobic and hydrophilic moieties. Due to such nature, solubility of hydrophilic molecules is increased alongwith reductions in surface and interfacial tensions at the oil/ water interface [1]. Surfactants a...
