Day to day activities of urban population in normal routine conditions are largely affected by the operation of the urban water supply system. In addition, the working hours, pattern of shift duties and living standards in a society decide the quantum of water use at different times in a day. This demand pattern is an important parameter for water supply agencies in order to ensure safe and reliable water supply. In the present study, short term (hourly and daily) water demand is estimated for drinking as well as various other household activities. BIS standards of 135 lpcd and socioeconomic survey data are considered as the basis to derive a time series distribution of water consumption for different activities. Monte Carlo simulation (MCS) is performed to generate the random distribution of consumption pattern. The hourly water consumption for various activities shows persistent behavior with Hurst coefficient in the range of 0.592 to 0.837 and the peak flow factor of the estimated demand pattern is 5. This pattern is useful as a basis for design of service reservoir as well as pump scheduling. It is also an important parameter in the model study in performance assessment of water distribution system (WDS).

Multivariate statistical techniques, including cluster analysis, principal component analysis factor analysis and discriminant analysis, have been used to evaluate spatial variations and to interpret a large and complex water quality data set collected from the Godavari river basin. The data sets, containing 7 parameters, were generated during the 3-years (2007-2009) at 78 different sites along the river and its tributaries. Water quality indices based on four parameters (pH, DO, BOD and FC) calculated for all the sites were found to be medium to good, good to excellent and bad using modified NSF index. Three significant groups (cleaner, slightly and moderately polluted sites) were detected by CA method, and three latent factors were identified by PCA method. The results of DA revealed that only two parameters (i.e. pH and BOD) were necessary for analysis in spatial variation. 83.3% of the original sites were correctly.classified using discriminant function developed from the analysis.

In the present study, the feasibility of a bioengineered two-stages sequential batch reactor (BTSSBR) followed by filtration?adsorption process was investigated to treat the agrochemical effluent by overcoming factor affecting process stability such as microbial imbalance and substrate sensitivity. An air stripper stripped 90% of toxic ammonia, and combined with other streams for bio-oxidation and filtration?adsorption. The BTSSBR system achieved bio-oxidation at 6 days hydraulic retention time by fending off microbial imbalance and substrate sensitivity. The maximum reduction in COD and BOD by heterotrophic bacteria in the first reactor was 87% and 90%, respectively. Removal of toxic ammoniacal-nitrogen by autotrophic bacteria in a post-second stage bio-oxidation was 97%. The optimum filtration and adsorption of pollutants were achieved at a filtration rate of 10 and 9 m3 m?2 h?1, respectively. The treatment scheme comprising air stripper, BTSSBR and filtration?adsorption process showed a great promise for treating the agrochemical effluent.

A nationwide study was carried out to develop air pollution source profiles specific to India. Chemical speciation profiles are reported for 27 major non-vehicular sources of particulate matter (combustion and non-combustion) in six cities in India viz. Bengaluru, Chennai, Delhi, Kanpur, Mumbai and Pune. PM10 and PM2.5 samples were collected from these sources using three different modes of sampling viz. dilution, resuspension and source dominated sampling, depending on the nature of the source. Filter samples were analyzed for mass by gravimetric analysis, elements by Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES), water soluble ions by ion chromatography and elemental (EC) and organic carbon (OC) by thermal/optical reflectance. Reported profiles include 39 elements, 12 ions, EC and OC. Developed profiles are compared with similar profiles that have been reported previously.

The present status of existing crocodile species has increased the necessity to develop novel utilities for conservation. We have developed 18 microsatellite loci from the Indian Gharial (Gavialis gangeticus) intended for genomic explanation and applied them to study genetic variation. Polymorphism of each locus was assessed in 32 individuals for G. gangeticus India. The number of alleles per locus varied from 2 to 8 (mean 5.5) for Indian population. Observed and expected heterozygosity ranged from 0.73 to 1.00 and 0.50 to 0.81, respectively and the average polymorphic information content is 0.565. These selected markers are helpful for assessing population structure, intraspecific difference, and conservation and management of G. gangeticus.

All crocodilians are under various threats due to over exploitation and these species have been listed in Appendix I or II of CITES. Lack of molecular techniques for the forensic identification of confiscated samples makes it difficult to enforce the law. Therefore, we herein present a molecular method developed on the basis on 16S rRNA gene of mitochondrial DNA for identification of crocodile species. We have developed a set of 16S rRNA primers for PCR based identification of crocodilian species. These novel primers amplify partial 16S rRNA sequences of six crocodile species which can be later combined to obtain a larger region (1290 bp) of 16S rRNA gene. This 16S rRNA gene could be used as an effective tool for forensic authentication of crocodiles. The described primers hold great promise in forensic identification of crocodile species, which can aid in the effective enforcement of law and conservation of these species.

The biodiversity of India includes three crocodile species, Crocodylus palustris, Crocodylus porosus, and Gavialis gangeticus, whose status is threatened due to bushmeat crisis and illegal hunting. The crocodilian conservation management requires novel techniques to help forensic analysts to reveal species identity. DNA barcoding is a species identification technique, where a partial cytochrome c oxidase subunit 1 gene is used as a marker for species identification. Herein, the DNA barcoding technique is evaluated for three Indian crocodiles by analyzing an approximately 750-bp barcode region. The alignment result shows interspecific variations between sequences for discrimination of the three Indian crocodiles leading to species identification. The phylogenetic analyses also substantiate the established crocodilian relationships, which add further advantage to use this DNA barcoding approach for Indian crocodiles. This study provides preliminary evidences for the use of DNA barcoding technique in the identification of Indian crocodile species.

"Electronic waste or E-waste comprises of old, end-of-life electronic appliances such as computers, laptops, TVs, DVD players, refrigerators, freezers, mobile phones, MP3 players etc. which have been disposed of by their original users. E-waste contains many hazardous constituents that may negatively impact the environment and affect human health if not properly managed. The problem of E-waste has forced Environmental agencies of many countries to innovate, develop and adopt environmentally sound options and strategies for E-waste management, with a view to mitigate and control the ever growing threat of E-waste to the environment and human health. E-waste management is given the top priority in many developed countries, but in rapid developing countries like India, it is difficult to completely adopt or replicate the E-waste management system followed in developed countries due to many country specific issues viz. socio-economic conditions, lack of infrastructure, absence of appropriate legislations for E-waste, approach and commitments of the concerned, etc. The paper presents E-waste scenario in developing countries, E-waste composition, categorization, prospects of recoverable, recyclable and hazardous materials found in the E-waste, recycling and recovery options followed And the overview and need of the laws and regulation related to E-waste for better E-waste Management."

Water Quality Analysis of Surface Water: A Web Approach (Environmental Monitoring and Assessment)
(Meenal Chourasia,185(7) ,,5987-5992, Year: 2013)
|

The chemical, physical and biological characteristics of water with respect to its suitability describe its quality. Concentration of pesticides or fertilisers degrades the water quality and affects marine life. A comprehensive environmental data information system helps to perform and complete common tasks in less time with less effort for data verification, data calculations, graph generation, and proper monitoring, which helps in the further mitigation step. In this paper, focus is given to a web-based system developed to express the quality of water in the imprecise environment of monitoring data. Water samples were analyzed for eight different surface water parameters, in which four parameters such as pH, dissolved oxygen, biochemical oxygen demand, and fecal coliform were used for the water quality index calculation following MPCB Water Quality Standards of class A-II for best designated use. The analysis showed that river points in a particular year were in very bad category with certainty level of 0-38% which is unsuitable for drinking purposes; samples in bad category had certainty level that ranged from 38 to 50%; samples in medium to good category had certainty levels from 50 to 100%, and the remaining samples were in good to excellent category, suitable for drinking purposes, with certainty levels from 63 to 100%.
