One of the key aims of this research is to formulate a more effective, sustainable and politically feasible pollution management approach for the Buriganga River. This was pursued through several avenues, including the analysis of river and waste water quality; the assessment of the existing river pollution control system; and the economic analysis of three alternative policies for water pollut...
Heavy metals are known to cause deleterious effects on human health through food chain. Human health risks were evaluated from consumption of heavy metal contaminated fish from Buriganga River in Bangladesh. Whole body of five fish species (Puntius ticto, Puntius sophore, Puntius chola, Labeo rohita and Glossogobius giuris) were analyzed which contained various concentrations of Cd, As, Pb, Cr,...
The efforts of modern civilization to create an environment to meet human aspirations have successfully resulted in constant improvements of our lifestyle, but it has increased risks to human and ecological health. This situation has motivated many scientists throughout the world to analyze the environmental factors that can affect our health or ecology and to calculate the levels of risk. In B...
Four central rivers of Bangladesh were selected for this research. The name the is Buriganga, Dhaleshwari, Shitalakshya and Meghna. Electrical Conductivity (EC), pH, Total Dissolved Solid (TDS), Salinity four river waters evaluated. EC values water Meghna found to be 366.0, 299.2, 290.4 130.8 µS/cm respectively. Similarly, pH 7.67, 7.38, 7.30 7.18 higher Buriganga than that other three waters. ...
The physico-chemical properties of tannery and textile effluents and water of adjacent river (Buriganga and Karnatoli, Dhaka) at three different locations were studied. The physico-chemical properties such as Biological OxygenDemand (BOD), salinity, Total Dissolved Solid (TDS), Total Suspended Solid (TSS), Sodium (Na ), Potasium (K ), Calcium (Ca ), Iron (Fe ), Phophate (PO ), Chloride (Cl ), N...
In order to formulate an improved system to control pollution in the Buriganga River, it is necessary to evaluate the effectiveness of the existing management practices. This chapter discusses the performance of the present system in terms of several aspects such as relevant national policies, legislative framework, organisational capacity, monitoring and enforcement status and extent of public...
Water and sediment samples were collected from 20 location of the Buriganga river of Bangladesh during Summer and Winter 2009 to determine the spatial distribution, seasonal and temporal variation of different heavy metal contents. Sequential extraction procedure was employed in sediment samples for the geochemical partitioning of the metals. Total trace metal content in water and sediment samp...
the spatial and temporal distribution of heavy metals in water, sediment and fish (dry weight basis) of buriganga river, bangladesh were determined by atomic absorption spectrophotometer. in water concentration of pb, cd, ni, cu and cr varied seasonally and spatially from 58.17 to 72.45î¼g/l, 7.08 to 12.33î¼g/l, 7.15 to 10.32î¼g/l, 107.38 to 201.29î¼g/l and 489.27 to 645.26î¼g/l, respectively. ...
Buriganga, an economically important river located around the industrialized urban area of Dhaka city, Bangladesh. In this study, 17 water quality parameters (EC, pH, TSS, temperature, F-, Cl-, SO42-, Cr,...
