Abstract: Noise is a disturbance to the human environment and will become a major threat to the quality of human lives. In last few decades, noise in urban areas have been increasing rapidly. Noise pollution was analysed in 10 different squares (road sections) during four different specified times (7-10 a m., 11 a m-2 pm, 3-6 pm, 7-10 pm ) to assess the level of noise pollution of the Rayagada township. The sources of noise at the studied sites were predominantly attributable to motor vehicular traffic. Noise descriptors such as L10, L50, L90, Leq, TN1 (Traffic Noise Index), NPL (Noise Pollution Level) and NC (Noise climate) were analysed to reveal the extent of noise pollution of this town L10, L50, L90, Leq, TNI, NPL and NC values of all 10 monitored sites ranged from 85.4 to 99.3 dB, from 72.6 to 86.5 dB, from 64.6 to 76.7 dB, from 80.4 to 99 dB, from 95.2 to 128.2 dB, from 95.1 to 159.2 dB, and from 13.3 to 30.3 dB, respectively. The present nosie assessment depicted that even the minimum values of Leq (80.4 dB), NPL (95.1 dB), TNI(95.2 dB) during day time were more than the permissible limit (70 dB). The number of vehicles passing through a fixed point on the studied road are counted to assess the traffic volume (Q) and the percentage of heavy trucks and buses to total traffic was also calculated to work out truck traffic mix ratio (P). Moreover, individual contribution to environmental noise by the air horn of different motor vehicles has also been assessed during day time. The episodic and impulsive noise levels of different tpes of vehicles were more than the traffic noise-limit i.e. 70 dB (A). A survey adopting questionnaire method amongst 241 local inhabitants had also been carried out to gather information regarding the effect of noise on human health.

Abstract: The Coastal-Oceanic ecosystem of Bangladesh contains a highly functional and structurally diverse ecology. The present sudy focusses an overivew of trace metals concentration in subsurface water and surficial sediment off Bangladesh coast in the Bay of Bengal. Samples were collected during spring on March and April 2007 and the concentration of trace metals in water were recorded as Ca 593.71+59.28? g/L, Mg 1029.02 + 104.77? g/L, Cu 0.56 +0.22 ? g/L, Fe 11.84 +2.77 ? g/L, Mn 4.74 + 2.24 ? g/L and Zn 1.66 +1.18 ? g/L and in sediment Ca 10.54 +2.50 ? g/g, Mg 5.55 +1.42 ? g/g, Cu 10.59 +7.47 mg/g, Fe 20.5+7.42mg/g, Mn 29.55 +7.91 mg/g and Zn 0.59 +0.17 mg/g respectively. Correlation co-efficient showed that trace metal in water and sediment were significantly interrelated. One-way ANNOVA showed that there is no significant differences in trace metals distribution in water and sediment throughout the Bangladesh coast. The finding of the present study is a baseline reference for developing water and sediment quality index of the coastal oceanic zone of Bangladesh.

Keywords: Abundance, Mahanadi river, Taladanda canal, zooplankton
Abstract: Zooplankton forms an important component of fish fries and helps to transfer energy from primary to secondary and tertiary levels in a food chain. Realizing the paucity of patent literature on the zooplankton population of sewage-fed river Mahanadi, studies were undertaken to assess the seasonal dynamics of zooplankton populations and nutrient status of water for a period of one year covering three seasons. Zooplankton population and water analysis was performed using standard procedure. Maximum population density was observed in the winter season followed by summer and lastly rainy. Higher zooplankton populations were encountered in Sikharpur (site IV). They corresponded to the fluctuation of prevailing conductivity, turbidity, dissolved oxygen, better organic load and chemical oxygen demand content of the said habitat. A total of 14 species belonging to six different groups were recorded during the study period. Lower concentration of zooplankton at Sikharpur site indicates polluted zone of the river. Our findings highlighted the deterioration of water quality in the river due to industralization and human activities. Proper biological and chemical treatment of domestic sewage and industrial effluents before discharge to river system is suggested.

Keywords: Dye, sorption, date palm, kinetics
Abstract: Acid activated date palm tree powder is proposed as an adsorbent for the removal of acid dye, Acid Blue 92, in this study. The influence of operating varaibles like solution pH, adsorbent dosage and initial dye concentration are studied thoroughly to evaluate the optimum conditions. Maximum adsorption was foudn to take place in pH 2.0 while equilibrium was achieved in 6 h. The mechanism of adsorption was explored by Pseudo-second order and Elovich models and it was found that this sorption process is well represented by Elovich model with a higher value of R2= 0.997. The physciochemical properties of the adsorbent are also studied.

Abstract: Puri city is situated near Bay of Bengal where there is a balanced interface of sea water and fresh water near the coast line. the city receives water from the ground water sources and the quality of ground water is being maintained. The main objective of the paper is to assess the quality of ground water using statistical techniques and the suitability of this water for its utility was verified using Indian drinking water standards. Goundwater samples were collected from various specific areas during post and pre-monsoon seasons and analyzed for physico-chemical and bacteriological parameters and compared with standards. The ground water is mainly polluted due to the domestic effluent, which contains detergents, human and animal excreta, industrial waste and cremation of human and animal bodies. The study showed that concentration of quality parameters were more in the city area as compared to the water fields due to the various anthropogenic activities taking place in the city. Based on the spatial and temporal assessment of groundwater quality, various mitigation measures were suggested for improving the groundwater quality of the Puri-city.

Keywords: Damodar river, water quality index, sensitivity index, water quality managment
Abstract: The objective of the study is to evaluate and compare the water quality of river Damodar for drinking purposes using Water Quality Index (WQI) and Sensitivity Index (SI) respectively. WQI gives information about spatial and seasonal variations of pollution load and to classify river water into five classes: Excellent, Acceptable, Slightly polluted, Polluted and Heavily polluted for drinkign purposes. However, SI gives an idea about whether quality of water is increasing or decreasing at same point during subsequent monitoring. Both were estimated using two separate computer programs; written in C language based on the eleven water quality parameters such as pH, DO, BOD, TDS, TSS, Cl-, NO3--N, SO42-, THARD, T-alkalinity, and T-coliform. A total 76 water samples were collected from 19 sampling points of a stretch D/S Tenughat dam to D/S Barakar river in mid-upper Damodar Valley to estimate spatial and seasonal variations in water quality for the year 2010. The values of WQI were found in the range of 66.2-75.6 in summer, while it was 55-76.0 in winter, affected mainly due to high values of total coliform, TSS and pH, exceeded the tolerable limits of IS:10:500 (1993) at almost all the sampling points. The results indicate that all sampling points were falling in the Acceptable (C2) to Slightly polluted (C3) range, except at Garga nalla [Polluted (C4) category]. This study demonstrates the application of WQI using computer programming tool for quick assessment of water quality of any water body and also can be used for effective water quality management.

Keywords: Wetland, images, degradation, drainage
Abstract: Degradation of wetland creates adverse impact on natural environment, ecosystem and on drainage congestion. The situation is more alarming in case of urban areas especially Dhaka and its adjacent areas. The objectives of the study are to determine the status of wetland reduction around Dhaka city in terms of extent of area and causes responsible for degradation. Satellite images of 1967, 1977, 1989, 1999, 2009 and 2010 have been used for preparing permanent wetland maps while satellite images of 1996 and 2009 have been used for preparing seasonal wetland status. Analysis showed that extends of permanent wetlands have been reduced in all the study areas during 1996-2009. Wetland degradation was found to be worse in eastern Dhaka followed by western Dhaka and Dhaka-Narayanganj-Demra (DND) areas. In case of Seasonal Wetlands, western Dhaka showed almost two-time more degradation than that of eastern Dhaka in caseof areal extension, when the same period of 1996-2009 is considered. Extensive increase of population and commercially productive use of land within the city are mainly responsible for this degradation. Demand driven urban growth that has profound adverse effects on the water resources and the wetland system in Dhaka have caused adverse impacts on the drainage systems. Unplanned urbanization has hampered the natural state of drainage, and hence caused suddent inundation and water-logging. Another major reason for seasonal wetland degrdation is loss of the connectivity of floodplains within the study area.

Keywords: Ecology, natural resource goverance, individual rights, collective capacity, Kole wetland, development, arresting development
Abstract: Valuing ecology on the basis of its contributions to environment protection is getting less social acceptance in contemporary development governance. Although, there are multiple models and approaches to tackle the question of ecology, the development governance still prefers to put economic value on ecology. The use value of ecology is becoming an administrative instrument, which often undermines the environment. The impact of this changing perception of ecology is well reflected in natural resource governance. It has become an issue of statisfying individual needs rather than sustainable utilization of resources. This goverannace is heading towards the project of arresting development; indeed it is becoming an unacceptable solution.

Abstract: Recently, mixed metal oxide (MMO) appears be a promising material for the removal of textile dyes. In our previous investigation with nickel-cobalt mixed oxide, anionic dye was removed (~70%) by the matrix. In the extension of our study, copper-cobalt mixed oxide is studied to search for a superior adsorbent. Results demonstrated copper-cobalt mixed oxide as a better option to other oxide adsorbents.
A simple chemical route was followed to prepare MMO matrix by precipitating the corresponding metal carbonates and heating the mixture of carbonates at 6500C under ambient atmosphere. IR, SEM and XRD methods were used to inspect the prepared MMO, while composition was studied by EDX analysis. UV-Vis was carried out for the adsorption studies. An anionic dye and a cationic dye were used to study the oxide matrix as adsorbent. It has been shown that anionic dyes can be removed completely at low pH with the MMO matrix.
