Abstract: The quality of water is of vital concern for mankind since it is directly linked with human welfare. The tremendous increase in industrial activity during the last few decades and the release of obnoxius industrial wastes into the environment have been o considerable concern in recent years from the point of view of Environmental pollution. Environmental pollution on one hand and deforestation and population explosion on the other, are threatening the very existence of life on earth. At present, the menace of water-borne diseases and epidemics still looms at large on the horizons of developing countries. Polluted water is the culprit in all such cases. The major sources of water pollution ae domestic waste from urban and rural areas and industrial wastes which are discharged into natural water bodies. The physical condition of water (colour, taste and odour) might render it undrinkable.

Subject: Heavy metal concentrations in soils and sediments of Visakhapatnam mangroves with special references to pollution risk
Keywords: Mangrooves, tidal creek, sedimentquality, heavy metal pollution, ecological risk index.
Abstract: Distribution of metals in water bodies may consequently be accumulated in sediment and soil because of low solubility after that become sensitivity indicator for mangroves. Heavy metal pollution due to sewage and industrial effluents was recognized as a serious threat to mangrove ecosystems. Visakhapatnam intertidal creek, Vishakhapatnam Port entrance Channe (VEC), is one such area receiving huge quantities of city sewage and from the nearby industrial zone, which includes petrochemical and fertilizer industries. All these discharges reach the entrance channel through various branches of the Meghadri Gedda, a small river drain. The present study reports the heavy metals accumulated in the soils of the mangrove region and sediments of the drain beds associated with the Visakhapatnam Entrance Channel in an attempt to compare with the available guidelines related to soil and sediments of the coastal wetlands. About six heavy metal pollutants concentrations (Cd, Cr, Cu,Mn,Pb,Zn) were recorded from the Visakhapatnam Entrance Channel soils and sediments and the ecological risk of these metals was computed based on the risk indicators. Results of the study revealed that the accumulation of metals in the sediment was relatively high compared to that in soils. The ecological risk potential (Eir) recorded was in the order of Cd>Pb>Cr>Mn>Zn>Cu indicating that the ecological risk from Cd was high. The study suggests the need for the development of coastal and marine sediment quality guidelines for India.

Abstract: The present study has been made to evaluate the status of physico-chemical contaminants in river Ghaggar in Punjab State. It receives a huge amount of waste, as it passes through urban and industrial areas. Therefore, the assessment of water quality of river Ghaggar is done at seen sampling points in Punjab from 2002 to 2015 for pre-monsoon and post-monsoon seasons. The physico-chemical parameters, such as pH, electrical conductivity (EC), dissolved oxygen (DO), biological oxygen demand (BOD), chemical oxygen demand (COD), total coliorm ,faecal coliform and No3 have been analysed. The results were compared with water quality standards prescribed by Bureau of Indian Standards (BIS) and World Health Organization (WHO).The correlation coefficients were calculated to identify highly correlated parameters. The study suggest that the quality of river Ghaggar becomes extremely deteriorated due to industrial and domestic discharge in the river.

Keywords: Plantations, carbon sequestration, Hevea brasiliensis, Kanyakumari, CO2 mitigation
Abstract: The effects of atmospheric carbon dioxide (CO2) concentrations and mitigation of CO2 attracted attention and found a place in the budget of different states all over the world. Co2 mitigation gained prominenece from the second half of the 20 centuries with initiatives taken by the institutions of international importance. Biotic and abiotic sequestration techniques are validated with additionality, permanence and leakage and biotic carbon sequestration through terretrial ecosystems was identified as a viable option due to its low cost. In this context, the present paper attempted to estimate the carbon sequestration potential of Hevea brasiliensis plantations in Kanyakumari, the southern-most district of India. The development of market mechanism for sequestered carbon widened the investment opportunities and provides economics incentives to the plantares in counties enormous forest resources. The carbon flux of plantations will provide a time span for policy makers to arrive at a convincing solution for sustainable development. The present study estimated that the Hevea brasiliensis plantations of Kanyakumari district is sequestering 647069 t CO2 and thereby eligible to earn $19.41 million through carbon trading.

Subject: Artificial recharge by surface runoff harvesting from perennial rivers
Keywords: Artificial recharge, Surface runoff harvesting, perennial rivers
Abstract: A majority of cities and town in the whole country are dependent on groundwater for their drinking water supply. This resource is being exploited unrestrictedly due to shortage of surface water supply. The groundwater withdrawal has increased tremendously over the last few decades. The groundwater quality has been adversely affected due to various human activities. The need of the hour is urgent remedial management measures to overcome these problems and also to provide a sustainable resource for the future generations. Rainwater harvesting has been used in the past but this is beneficial only during the monsoon seasons. Therefore, it is essential to switchover to remedial measures, such as runoff water harvesting to recharge the groundwater and arrest the declining trend of groundwater level and quality deterioration. In our country majority of the rainfall reaches the sea and thus remains inaccessible for human consumption. In this paper, a novel technique for recharging the groundwater aquifer using surface water from the perennial rivers is being proposed so as to provide a constant subsurface recharge throughout the year. Moreover, this recharge can be used to fill the surrounding percolation tanks, ponds, etc. Which would immensely benefit the neighborhood in terms of crop irrigation and drinking water supply. In addition, this technique can reduce the soil erosion in the perennial rivers and enhance the fertility of the dry lands in the vicinity of the recharge area.

Abstract: Banana pseudostem acts as potential feedstock for biofuel production but, their conversion into fermentable sugars is a major complication. The present investigation reveals the production of ethanol from the banana pseudostem with the help of biological treatment using white rot fungi, like Phanerochaete chrysospreium carried out by SMC (submerge) and solid state (SSC) cultivation. The hydrolysis was done by Aspergilus niger, Aspergillus fumigates, Trichoderma reesei and mixed culture of all fungus. Finally, the fermentation was done by Saccharomyces cerevisae, Pichia stipitis and Candida shehatae. At solid state cultivation condition phanerochaete chrysosporium using Trichoderma reesai fermented by Pichia stiptis gives better result in case of pseudostem.

Keywords: PM 2.5, mass concentration, Beta attenuation monitor, gravimetric method
Abstract: Particulate air pollution, specifically PM 2.5 is known to cause cardiovascular diseases in human being9Wang et al., 2015). Because of its health effect, it is a major parameter of the National Ambient Air quality standards (NAAQS). In the National Ambient Air Quality Standards, three methods of the measurement of PM 2.5 are recommended. In this study, two such measurement methods were used simultaneously and compared at various locations at Raipur city in Chhattisgarh state. Gravimetric method has been one o he conventional methods for the measurement of PM 2.5 and has been approved by US EPA as reference method, also by many governing bodies. With the recent advancement in the field of technology there are several methods, which are almost equivalent to the gravimetric method. Among these, beta attenuation monitor (BAM) is the most widely acclaimed technology used all over the world for several years. In this work, PM 2.5 was sampled using a filter-based gravimetric sampling method and direct reading instruments (that is beta attenuation monitor) a location in Raipur city, namely Naya Raipur monitoring station during Diwali festival week and mass concentration results were compared. In general, we observed that the deviation in the results obtained by both the methods is larger when ambient relative humidity is high (>50%)

Abstract: In this present work, activated carbon (AC) prepared from Sterculia foetida seed sheels plant by the combination of hydrothermal and chemical activation method. To remove the heavy metal prepared activated carbon is used as an adsorbent. Here, it is demonstrated the use of hydrothermal carbonization-derived activated carbon for such an application. The morphology of carbon and activated carbon was characterized by scanning electron micoscopy (SEM).Fourier-transform infrared spectrometer (FTIR) was used to confirm activation. Surface area and pore size analysis results allow for comparison of the degree of activation. The experiments were conceded by to study the adsorption phenomenon by varying parameters, like contact time, metal concentration and adsorbent dosage. The data obtained from this study were assessed by Langmuir and Freundlich isotherm. Among the equilibrium data, Freundlich isotherm is well adapted and implies that the metal adsorption on activated carbon is heterogeneous. The kinetic data were established to follow closely the pseudo-second order model. The surface morphology of the activated carbon was observed by XRD and BET. The maximum adsorption efficiency of the activated carbon for the removal of mercury ion was determined 89%.

Subject: Experimental study on water for flow uniformity
Keywords: Flow separation, Velocity, film thickness, drag coeficient, spillway weir
Abstract: Many radioactive problems due to the non uniform cooling o reactor components in sodium cooled fast breeder reactors signified the importance of spillway weir system. The spillway weir profiles play a predominant role in the cooling of sodium cooled fast breeder reactor components and many chemical processing units. The profiling of weir had been a critical issue need to be considered regarding flow separation point of view. The separation of sodium flow causes entrainment of argon cover gas and hence reactivity problems. This paper describes the effect of sill way profile on flow separation studies, measurement of velocity of water for achieving uniform conditions, measurement of film thickness and drag coefficient of water for various flow rates. In this experiment, sodium had been simulated as water and argon as air considering the Froude number and Webner number and results are highlighted. This paper aims to bring out the suitable hydraulic design and production of profile which suits to minimize the flow separation of water over the crest of the weir. The thickness of water over the weir profile directly influences the flow separation. A water flow velocity meter had been used to measure the velocity of water in the upstream side and an ultrasonic sensor with Arduino and LCD setup had been for measuring the film thickness of water in cyclindrical coordinates. Based on the measurements taken, mean drag coefficient had been arrived.

Abstract: The challenge on environmental sustainability before India is taking a frightful shape when it comes to the pollution of water. The long stretch of Ganga which is regarded as the holy flow is being messed up by the different anthropogenic activities. Ganga has now become contaminated in its many arms giving rise to a question to our water availability. There has been a long tradition of idol immersion and is too popular in the Ghats of Kolkata whose harmful effects are creating alteration on various components of a river f which water and soil are the most prominent. In this study in order to curb such situation and to establish a rapid assessment the physico-chemical parameters of water samples were collected from different hotspot areas at before and after idol immersion activity and were analyzed as prescribed by APHA guideline. Soil samples were also collected from the same position and tested accordingly in the laboratory of School of water resources Engineering. Jadavpur University. Water quality index (WQI) was calculated using the result indicated an increase in pollution load after immersion and quality deterioration characteristics change as well. The water quality index values reflected that an overall water quality is getting deteriorated at a greater extent immediately when the idol immersion process is going on. The result also highlighted that higher amount of lead was used as a raw material received in the river Ganga which may come from idol immersion. Thus, it can be concluded that the overall health condition of river Ganga is getting hampered which may reduce the saturation value of dissolved oxygen and disturb the ecological flow at higher rate near by the bank.
