Heavy Metals Contamination in Water and Sediments of an Urban River in a Developing Country
Int. J. Environ. Sci. Tech., 8 (4), 723-736, Autumn 2011 ISSN 1735-1472 K. M. Mohiuddin et al. © IRSEN, CEERS, IAU Heavy metals contamination in water and sediments of an urban river in a developing country 1, 2*K. M. Mohiuddin; 3Y. Ogawa; 2H. M. Zakir; 1K. Otomo; 1N. Shikazono 1Laboratory of Geochemistry, School of Science for Open and Environmental Systems, Graduate School of Science and Technology, Keio University, Yokohama, Japan 2Department of Agricultural Chemistry, Bangladesh Agricultural University, Mymensingh, Bangladesh 3Graduate School of Environmental Studies, Tohoku University, Sendai, Japan Received 7 January 2011; revised 17 June 2011; accepted 3 August 2011 ABSTRACT: 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 samples were analyzed and compared with different standard and reference values. Concentration of total chromium, lead, cadmium, zinc, copper, nickel, cobalt and arsenic in water samples were greatly exceeded the toxicity reference values in both season. Concentration of chromium, lead, copper and nickel in sediment samples were mostly higher than that of severe effect level values, at which the sediment is considered heavily polluted. On average 72 % chromium, 92 % lead, 88 % zinc, 73 % copper, 63 % nickel and 68 % of total cobalt were associated with the first three labile sequential extraction phases, which portion is readily bioavailable and might be associated with frequent negative biological effects. -

Aquatic Ecology and Dangerous Substances: Bangladesh Perspective
Diffuse Pollution Conference Dublin 2003 8C Ecology: AQUATIC ECOLOGY AND DANGEROUS SUBSTANCES: BANGLADESH PERSPECTIVE Institute for Environment and Development Studies 5/12-15, Eastern view (5th floor), 50, D.I.T Extension Road, Dhaka -1000, Bangladesh. E-mail: [email protected] ; Phone: +880 2 9354128 ; Fax: +880 2 8315394 Bangladesh had always been predominantly and agricultural based country and in early days pollution was never even felt in this region. Since early sixties, of necessity, industries of various kinds started to spring up slowly. It appears in a survey that ecological imbalance is being caused continuously due to discharge of various industrial wastes into air and water bodies. It has also been found that the intensity of pollution caused by the factories and industrial units depend on their type, location, raw materials, chemical effects, production process and discharge of gaseous, liquid and solid pollutants to the natural environment. All of Bangladesh's sewage and industrial wastes are flushed directly into Ganges and Brahmaputra Rivers. There are wide spread fears that as the region develops in industrial infrastructure, industrial pollution will accelerate, compounding the problems posed by raw municipal wastes. About 900 polluting industries in Bangladesh dispose of untreated industrial wastes directly into rivers, although the effluents contain 10 to 100 times the allowable levels permissible for human health. The Ganges-Brahmaputra delta is the largest delta in the world and the rivers contribute one-third of the global sediment transport to the world oceans. The rivers flow through 10 per cent global population and carry untreated rural, urban, municipal and industrial wastes to the Bay of Bengal. -

5. PRELIMINARY FACILITY DESIGN 5.1 Preliminary Design of River
THE FEASIBILITY STUDY OF PADMA BRIDGE FINAL REPORT – EXECUTIVE SUMMARY - MARCH 2005 results of simulations suggest that the hydraulic design parameters for the preliminary designs are appropriate and adverse impacts due to the project construction will be minor in terms of hydrodynamics and river morphology for the design flood under 2003/04 conditions. The impacts, indicated as the differences in the ‘without project’ and ‘with project’ scenario conditions, are minor as a whole. For the design flood of the 100-year return period, the increment of the highest water level is almost negligible and only a +0.1m/sec increment would occur in the depth-averaged flow velocity. Two-dimensional Modeling and Simulation (2003/04 Padma 2-D Long-term Model): The long-term simulation represents the indicative tendency for riverbed scour or deposition for locations for periods of 5 and 10 years respectively. The simulation results suggest that no large impact in terms of mid- and long-term morphological processes would be expected from the project construction. (3) Estimate of Maximum Scour Depth Types of Riverbed Scour: Natural and structure-induced scours were taken into account in the estimation of maximum scour depth. The natural scour was estimated as the sum of bend and confluence scours that could occur simultaneously under the worst case scenario, while structure-induced scours such as those around the bank protection works and bridge piers were calculated under natural scour flow conditions. Design Maximum Scour Depth (DMSD): A total scour depth was calculated assuming the worst combination of the relevant types of scour. In order to account for extra scour, which may be induced by unforeseen and compounding structural influences, the total scour was multiplied by a factor of 1.20 to determine the design maximum scour depth (DMSD). -

In order to screen metal pollutant levels and to assess ecological risks, this study was conducted on water and sediment samples from the Buriganga River. A total of 13 metals in water and sedi- ment samples were determined by atomic absorption spectroscopy. For sediment samples, the geo- accumulation index (Igeo), contamination factor (CF), potential ecological risk index, and pollution load index (PLI) were calculated. The Igeo increased in order of Ag > Pb > Cu > Zn > Hg > Cd > Cr > Co > Ni > As > Se > Sb > Be > Tl in both summer and winter seasons. -

Wahidul Alam* and Mohammad Zafar Institute of Marine Sciences and Fisheries, University of Chittagong, Chittagong-4331, Bangladesh *Corresponding author’s e-mail: [email protected] [Received: 16 October 2012, Revised: 15 November 2012, Accepted: 15 December 2012] ABSTRACT This study was carried out to examine the presence of Salmonella spp. in soil and water sample along with some physio-chemical parameters of water at the Karnafuli river estuary during March-June 2012 from 3 stations. The ranges of measured parameters of water samples were 26.5- 32ºC, 0.0 – 5.0‰, 7.5 – 7.9 and 2.28 – 2.91mg/l for temperature, salinity, pH and dissolved oxygen (DO), respectively.. In the present investigation, it was observed that the values of physio chemical parameters in the estuarine area were fluctuated seasonally. Water temp, salinity and pH were within acceptable range according to EQSB and guidelines value of WHO but the concentration of DO decreased significantly indicating the deterioration of estuarine environment including water quality and soil conditions which are influenced by higher bacterial growth in the polluted estuarine zone. Maximum Salmonella spp. concentrations were observed 5cells/ml in soil from one station (St-1) out of 3 total sampling stations during the month of May. The occurrences of Salmonella spp. was not found many of the stations they were absent. -
