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. -

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. -

Assessment of Heavy Metals and Water Quality Parameters of Buriganga River of Dhaka, Bangladesh: a Review
Quest Journals Journal of Research in Environmental and Earth Sciences Volume 6 ~ Issue 6 (2020) pp: 01-10 ISSN(Online) :2348-2532 www.questjournals.org Research Paper Assessment of heavy metals and water quality parameters of Buriganga river of Dhaka, Bangladesh: A review 1 2 2 2 Amena Ferdousi , M. Mostafizur Rahman , Sajjadul Bari , Ayesha Siddiqua 1Department of Computer Science, Eastern University. 2Department of Mathematics, American International University-Bangladesh. ABSTRACT: The intention of this work is to mark out the literature survey of water pollution of Buriganga River. Themethod used for this write-up is a survey of scholarly journal articles, web materials, academic books, conference papers, project reports and freely accessible materials on the Buriganga river water pollution. All previouswriters whose works werechecked,concurredon water pollution and spatial variation of physicochemical parameters over time and location more than other sources in terms of both chemical and physical water toxins that shownuplifted values of majorchemical parameters (lead, cadmium, chromium, copper and some anions) beyond the acceptable/lower limits set by administrative bodies. Authors also agreed on the issuethat human, aquatic and physical environment are in alarming situation due to rising values of chemical parameters. From the survey and analyzing the output of past studies, we can conclude that Buriganga river is polluted and water must be treated before use both fordomestic and industrial purposes to avoid the spread of epidemics. Proposals of the scrutiny incorporate: (1) consistentsurvey of Buriganga river water pollution; (2) strict organization of directions water quality benchmarks and (3) Well-planned monitoring of the environments of water bodies by authorities and the local people. -
The Calculus of Heritage Preservation
June 25, 2019 The calculus of heritage preservation Ruins of Jahaj Bari, which was torn down violating a High Court order and without permission from the Waqf Estate that the land belongs to. Photo: Collected Adnan Zillur Morshed The clandestine demolition of Jahaj Bari in Old Dhaka on the night of Eid-ul-Fitr reveals the precarious state of historic preservation in Bangladesh. Such a senseless act of destruction—a kind of cultural violence—was possible because of a host of interrelated reasons. Among them are: a lack of clear policy guidelines for the preservation of “historic” buildings in private hands or waqf custodianship; a policy marginality of the very idea of historic preservation within government bureaucracies; pervasive lack of knowledge of heritage buildings (a newspaper journalist called Jahaj Bari an “ancient” building; there is no consensus as to when exactly the building was built); absence of broad public heritage awareness, further weakened by a disjointed culture of sentimental attitude toward preservation, often falsely isolated from the economics of preservation. The knocking down of Jahaj Bari received some news media coverage. Yet, the overall feeling was that this was merely a minor headache of the preservation specialist! There was no statement about it on the website of the Department of Archaeology, the government agency in charge of the country’s cultural patrimony. This agency recognises only 32 buildings in Old Dhaka as archaeologically significant. Jahaj Bari is not one of them. According to the Urban Study Group, a team of activists committed to the conservation of historic buildings, there are 2,200 “heritage” buildings in Old Dhaka. -
