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.

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. -

Ecological Risk Assessment of Heavy Metals in Sediment of the Louhajang River, Bangladesh
Research Article Published: 04 Apr, 2019 SF Journal of Environmental and Earth Science Ecological Risk Assessment of Heavy Metals in Sediment of the Louhajang River, Bangladesh Kormoker T1*, Proshad R2 and Islam MS2 1Department of Emergency Management, Patuakhali Science and Technology University, Dumki, Patuakhali, Bangladesh 2Department of Soil Science, Patuakhali Science and Technology University, Dumki, Patuakhali, Bangladesh Abstract Heavy metal pollution in sediment of the riverine ecosystem is regarded as a major problem in developing countries like Bangladesh. The present study was conducted to assess the contamination level of heavy metals and their ecological in sediments of the Louhajang River, Bangladesh. Certain indices, including the enrichment factor (EF), pollution load index (PLI), geoaccumulation index i (Igeo), and contamination factor (C f) were used to assess the ecological risk. The mean concentration of Cr, Ni, Cu, As, Cd, and Pb in sediments was 9.205, 7.676, 17.727, 8.999, 0.083, and 4.597 mg/ kg, respectively. Metals in sediment during winter were higher than summer season. Enrichment i factor (EF), contamination factor (C f), geoaccumulation index (Igeo), and pollution load index (PLI) revealed lower contamination of sediments by the studied heavy metals. The sum of toxic units at different sampling sites was less than 4, indicating a low toxicity of heavy metals in sediments of the study river. Considering the severity of potential ecological risk for single metal, the descending order of pollutants was As > Cu > Cd > Ni > Pb > Cr. In view of the potential ecological risk, sediments of Louhajang River showed low potential ecological risk. Keywords: Surface sediment; Heavy metal; Ecological risk; Bangladesh Introduction Contamination of heavy metals in the environment has attracted a wide concern due to the ever- increasing pollution of soil, sediment and water in many regions of the world, especially in some developing countries like Bangladesh [1-6]. -

The present study attempts to evaluate the degree of heavy metal pollution, contamination, and accumulative behavior in the sediment of the Dhaleswari river. The sediment samples were collected from fifteen different locations of the Dhaleswari river. Heavy metals were analyzed using the Flame Atomic Spectrophotometer (FAAS). The mean concentrations of Zn, Cu, Cr, Pb and Cd were 131.9, 48.89, 43.16, 33.23 and 0.37 mgkg-1, respectively. According to the United States Environmental Protection Agency (USEPA) Sediment Quality Guideline, the sediment of most of the locations were not polluted for Pb and Cd. But S-11 location for Cd (0.8 mg kg-1) was highly polluted. -

Mondal, S.K. Bala, G.M.T. Islam, M.A. Haque, M.R. Islam & S. Biswas Institute of Water and Flood Management, Bangladesh University of Engineering and Technology, Dhaka-1000, Bangladesh ABSTRACT: Hydrological and morphological studies of about 50 rivers in Bangladesh have been done over the last few years. The studies were conducted in relation to 188number of bridges proposed to be constructed on these rivers. The hydrological studies included estimation of flood discharge, level, velocity, hydraulic depth, flow area, etc., based on flood frequency and/or model studies. Flood frequency analysis was carried out using the Lognormal, Gumbel’s Extreme Value Type I, Pearson and Log Pearson probability distribution functions. One-dimensional hydrodynamic model was also used to generate design hydraulic parameters at the selected river locations. The morphological studies included assessment of stability of the river sites using time series satellite image analysis, quasi-three dimensional morphodynamic modeling, cross-sectional analy- sis and field observations. Spatial distribution of various parameters was then investigated. The findings indi- cate that some areas/rivers are hydro-morphologically more active and vulnerable than the others. Even the vulnerability of the same river varies depending on the location. Accordingly, hydraulic intervention in some rivers are found to be more challenging than in others. 1 INTRODUCTION Bangladesh is a country of rivers. -

Copyright © Strategic Foresight Group 2013 ISBN 978-81-88262-19-9 Design and production by MadderRed Printed at Mail Order Solutions India Pvt. Ltd., Mumbai, India PREFACE At the superficial level, relations between India and Bangladesh seem to be sailing through troubled waters. The failure to sign the Teesta River Agreement is apparently the most visible example of the failure of reason in the relations between the two countries. What is apparent is often not real. Behind the cacophony of critics, the Governments of the two countries have been working diligently to establish sound foundation for constructive relationship between the two countries. There is a positive momentum. There are also difficulties, but they are surmountable. The reason why the Teesta River Agreement has not been signed is that seasonal variations reduce the flow of the river to less than 1 BCM per month during the lean season. This creates difficulties for the mainly agrarian and poor population of the northern districts of West Bengal province in India and the north-western districts of Bangladesh. There is temptation to argue for maximum allocation of the water flow to secure access to water in the lean season. -
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. -
