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. -

(LST) of Turag River in Bangladesh: an Integrated Approach of Geospatial, Feld, and Laboratory Analyses
Research Article Evaluation of water quantity–quality, foodplain landuse, and land surface temperature (LST) of Turag River in Bangladesh: an integrated approach of geospatial, feld, and laboratory analyses Afsana Hossen Tania1 · Md. Yousuf Gazi1 · Md. Bodruddoza Mia1 Received: 3 October 2020 / Accepted: 21 December 2020 © The Author(s) 2021 OPEN Abstract Rapid urbanization, industrialization, and development activities are posing numerous threats to the rivers of Bangla- desh. In the recent decade, Turag River has been exposed to severe threats due to anthropogenic activities. The present research deals with the evaluation of water quantity–quality, landuse and landcover (LULC), and land surface tem- perature (LST) of Turag River and its foodplain by using an integrated approach of feld study, laboratory analysis, and geospatial techniques. LULC mapping of the study area has been done using multi-temporal Landsat satellite images by unsupervised method, Normalized Diference Vegetation Index (NDVI) and Normalized Diference Water Index indices (NDWI) approach. From LULC classifcation, the study shows that the average reduction of water bodies from 1989 to 2019 is about 60–66%, and the rate of reduction is about 14.25 ha per year. Due to anthropogenic activities and rapid urbanization, a large number of water bodies have been depleting. The average temperature of the river water from fled observed data is 30.23 °C and from image processed data is about 28.32 °C. The minimum and maximum values of pH, EC, TDS, and Eh are 6.87–8.44, 808–1192 μs/cm, 406–739 ppm, − 31 to – 150 mV, respectively. The concentration ranges of cations (Na, Ca, Mg, K, Fe, and Mn) are 85.43–247.60, 28.59–39.47, 11.1–13.58, 5.21–13.26l, .07–1.14, .006–.47 mg/l con- 3− − 2− secutively. -

Tnpsc Bits Tamil Nadu
• • November – 03 TNPSC BITS ❖ Indian Railways has launched “Meri Saheli” initiative for focused action on security of women across all zones. o Its objective is to provide safety and security to lady passengers travelling by trains for their entire journey from starting station to destination station. ❖ The state government of Karnataka has proposed a ban on government servants acting in films and television programmes. ❖ The Indian Navy test fired the Anti-Ship Missile from INS Kora in Bay of Bengal. TAMIL NADU Fossils at Perambalur ❖ More than 25 concretions (ammonium sediments) were found in Kunnam (Perambalur). ❖ The round-shaped Phosphatic nodules, called Uttatur potatoes, were also available in Kunnam and Karai areas. ❖ A fossilised tree and ammonite sediments were also found in Aanaivari stream in the area. ❖ The ammonite (ammonoids) was a large and diverse group of marine species ❖ It originated around 416 million years ago during the Devonian period. ❖ Ammonites survived three mass extinctions. ❖ Out of that, the Permian extinction is the most notable one ❖ It was a global warming brought on by volcanic activity about 252 million years ago. ❖ It killed 96 per cent of the planet’s marine species. ❖ Some years back, the Archaeological evidence suggests that dinosaurs lived in the Ariyalur area of Tamilnadu 6.5 billion years ago. ❖ But the remains of the eggs are rarely found. ❖ Earlier Ariyalur and Perambalur were submerged in the sea in present-day Tamil Nadu. ❖ Fossils in Kunnam might have formed about nine billion years ago when the depth of the sea was about 100 metres in the Turonian-Cenomanian Cretaceous period. -

Problems of Salination of Land in Coastal Areas of India and Suitable Protection Measures

K. Puram, New Delhi-110066 FOREWORD Salinity is a significant challenge and poses risks to sustainable development of Coastal regions of India. If left unmanaged, salinity has serious implications for water quality, biodiversity, agricultural productivity, supply of water for critical human needs and industry and the longevity of infrastructure. The Coastal Salinity has become a persistent problem due to ingress of the sea water inland. This is the most significant environmental and economical challenge and needs immediate attention. The coastal areas are more susceptible as these are pockets of development in the country. Most of the trade happens in the coastal areas which lead to extensive migration in the coastal areas. This led to the depletion of the coastal fresh water resources. Digging more and more deeper wells has led to the ingress of sea water into the fresh water aquifers turning them saline. The rainfall patterns, water resources, geology/hydro-geology vary from region to region along the coastal belt. -

The demand of water is increasing day by day. So, groundwater resources play a vital role for additional demand by farmers and Industries and domestic usage leads to rapid development of groundwater. About 63% of available groundwater resources are now being used. However, the development is not uniform all over the State, and in certain districts of Tamil Nadu, intensive groundwater development had led to declining water levels, increasing trend of Over Exploited and Critical Firkas, saline water intrusion, etc. ADMINISTRATIVE SET UP The total geographical area of the Dindigul distict is6, 26,664 hectares, which is about 4.82 percent of the total geographical area of Tamil Nadu state.Thedistrict, is well connected by roads and railway lines with other towns within and outside Tamil Nadu.This district comprising 359 villages has been divided into 7 Taluks, 14 Blocks and 40 Firkas. -
