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. -
Revisit to Dhaka University As the Symbol of Bengal Partition Sowmit Chandra Chanda Dr
Academic Ramification in Colonial India: Revisit to Dhaka University as the Symbol of Bengal Partition Sowmit Chandra Chanda Dr. Neerja A. Gupta PhD Research Scholar under Dr. Neerja A. Director & Coordinator, Department of Gupta, Department of Diaspora and Diaspora and Migration Studies, SAP, Migration Studies, SAP, Gujarat Gujarat University, Ahmedabad, India. University, Ahmedabad, India. Abstract: It has been almost hundred years since University of Dhaka was established back in 1921. It was the 13th University built in India under the Colonial rule. It was that like of dream comes true object for those people who lived in the eastern part of Indian Sub-continent under Bengal presidency in the British period. But when the Bengal partition came into act in 1905, people from the new province of East Bengal and Assam were expecting a faster move from the government to establish a university in their capital city. But, with in 6 years, the partition was annulled. The people from the eastern part was very much disappointed for that, but they never left that demand to have a university in Dhaka. After some several reports and commissions the university was formed at last. But, in 1923, in the first convocation of the university, the chancellor Lord Lytton said this university was given to East Bengal as a ‘splendid Imperial compensation’. Which turns our attention to write this paper. If the statement of Lytton was true and honest, then certainly Dhaka University stands as the foremost symbol of both the Bengal Partition in the academic ramification. Key Words: Partition, Bengal Partition, Colony, Colonial Power, Curzon, University, Dhaka University etc. -
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. -

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.
