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. -
WIDER Working Paper 2020/44-Structural Transformation
WIDER Working Paper 2020/44 Structural transformation, inequality dynamics, and inclusive growth in Bangladesh Selim Raihan1 and Sunera Saba Khan2 April 2020 Abstract: The Bangladesh economy has undergone significant structural changes over the last four decades. The share of agriculture in GDP has declined, while the significance of industry and service sectors has increased. These structural changes have been associated with persistent challenges such as lack of diversification, poor working conditions, low productivity, and high degree of informality, obstructing the progress towards inclusive economic growth. Though manufacturing is now an overwhelmingly salient component of Bangladesh’s export composition, this is due primarily to the rapid expansion of the ready-made garments sector: the performance of other industries has been rather weak. In order to become a sustained, inclusive driver of economic growth and employment creation, the manufacturing sector needs to focus on expanding and diversifying its base. This study looks at the major challenges, both policy-induced and structural, for the required structural transformation in the Bangladesh economy, aiming to tackle inequality and promote inclusive growth. Key words: Bangladesh, structural transformation, inclusive growth, inequality, ready-made garments JEL classification: O14, O25, O40, O53 1 University of Dhaka and SANEM (South Asian Network on Economic Modeling), Dhaka, Bangladesh, corresponding author: [email protected]; 2 SANEM, Dhaka, Bangladesh.

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. -
