    • Authors: Priyanka Tiwari, Shelja K Juneja
      Pages: 1 - 13
      Abstract: This paper aims at management of floral waste generated from temples of Jaipur city through vermicomposting. In this study, flower waste consisted of variety of flowers out of which marigold was chosen as it was found in maximum amount. The vermibeds were prepared by mixing the marigold with cow dung in different proportions viz., 50:50, 60:40, 70:30, 80:20 and 90:10 and they were filled in the earthen pots, individually. Simultaneously, a control (without worms) for each of these concentrations was prepared and maintained. Eisenia foetida was introduced into each of these trays except the control. The bioconversion ratio i.e., waste into vermicompost was found to be high in 60:40 proportion than the others. Vermicompost obtained was analysed for various parameters like organic carbon, total nitrogen, phosphorus, potassium, calcium and magnesium. The amount of organic carbon, potassium and phosphorus was more in vermicompost samples for all the groups as compared to compost samples. It was concluded that floral waste with cow dung at 50:50, 60:40 and 70:30 ratios could be converted into a nutrient rich vermicompost. International Journal of Environment Vol. 5 (1) 2016,  pp: 1-13

    • Authors: Bernard Fei-Baffoe, Kenneth Osei, Eric Appiah Agyapong, Eugene Atta Nyankson
      Pages: 14 - 31
      Abstract: Co-composting organic solid waste with dewatered sewage sludge was carried out to determine its suitability for managing waste on a University campus. Windrow composting method was employed in which dewatered sewage sludge and organic solid waste were mixed at volume ratios: 1:1, 1:2, 1:3, 0:1 and 1:0 sludge/organic solid waste. Parameters such as pH, percentage N, C, P, K, Ca, Mg, organic matter, ash content and C/N ratio were determined weekly. Total and faecal coliform population were measured biweekly with Pb and Cd levels determined at the beginning and end of the composting. With the exception of ratio 1:0 sludge/organic solid waste, all other ratios attained a favourable Carbon to Nitrogen (C/N) ratio both at the start and end of the composting process. Levels of major nutrients measured were found to be favourable for use as organic fertilizer. There was a general decline in carbon and organic matter in all the compost piles except the sewage sludge pile (1:0). Apart from the compost ratio 1:0 sludge/organic solid waste, all other ratios attained a temperature of 55°C within 8 days of composting. Generally the compost ratios 1:2, 1:3 and 0:1 (sludge/organic solid waste) were found to be the most suitable for use as organic fertilizer.     International Journal of Environment Vol. 5 (1) 2016,  pp: 14-31

  • Assessment of surface water quality using hierarchical cluster analysis

    • Authors: Dheeraj Kumar Dabgerwal, Shailendra Kumar Tripathi
      Pages: 32 - 44
      Abstract: This study was carried out to assess the physicochemical quality river Varuna inVaranasi,India. Water samples were collected from 10 sites during January-June 2015. Pearson correlation analysis was used to assess the direction and strength of relationship between physicochemical parameters. Hierarchical Cluster analysis was also performed to determine the sources of pollution in the river Varuna. The result showed quite high value of DO, Nitrate, BOD, COD and Total Alkalinity, above the BIS permissible limit. The results of correlation analysis identified key water parameters as pH, electrical conductivity, total alkalinity and nitrate, which influence the concentration of other water parameters. Cluster analysis identified three major clusters of sampling sites out of total 10 sites, according to the similarity in water quality. This study illustrated the usefulness of correlation and cluster analysis for getting better information about the river water quality.International Journal of Environment Vol. 5 (1) 2016,  pp: 32-44

  • Determination of physiochemical properties of Gum Arabic as a suitable
           binder in emulsion house paint

    • Authors: Ali L. Yaumi, Ahmed M. Murtala, Habiba D. Muhd, Fatima M. Saleh
      Pages: 67 - 78
      Abstract: Gum Arabic “GA” is an organic adhesive produced from a tree called named Acacia Senegal. The gum has a wide range of industrial uses, especially in areas of feeds, textiles, and pharmaceuticals. It is used as emulsifier and serves mostly as stabilizer in both cosmetic and food products which contains oil water interface. GA sample was collected, formulated and prepared into various concentrations ranging from 20%w/v to 85%w/v. The quality and applicability of well characterized materials are directly related to their physical and chemical properties. From the physiochemical analysis, the result revealed that all the samples were slightly acidic (pH ranging from 4.81-6.41). This range is in good agreement with reported pH values for gum arabic and other Acacia gums by several authors. . The binding strength increases as the number of days increases for example in sample F (50%w/v) gum Arabic concentration increases from 1.5 in the 1st day to 1.97 in the 28th day. The samples prepared are denser than water which indicates that the density increases as the percentage concentration of the samples increases and the relative density of the gum solution is independent on time. The binding strength of sample G (75%w/v) gum concentration compared well to that of polyvinyl acetate (PVA). International Journal of Environment Vol. 5 (1) 2016,  pp: 67-78

  • Ecological study of periphyton diversity in crenic habitat of
           Sahashradhara (Garhwal Himalayas, India)

    • Authors: Anita Chauhan, Ramesh C. Sharma
      Pages: 79 - 95
      Abstract: A maiden attempt has been made to present a biodiversity of periphyton of the Sahashradhara springs, a group of one thousand springs and one of the most important clusters of limnocrenes and rheocrenes springs located in Doon Valley of Garhwal-Himalayas. The environmental monitoring of periphyton community of Sahashradhara springs was carried out for one complete annual cycle (October 2011-September 2012). Annual percentage composition of periphyton revealed that major contribution was represented by Bacillariophyceae (68-70%) followed by Chlorophyceae (26-28%) and Myxophyceae (3-5%). A total of 29 species of periphyton were recorded from different springs of Sahashradhara. A significant correlation between diversity of periphyton and environmental parameters- temperature, turbidity, conductivity, dissolved oxygen, free CO2, alkalinity, FPOM and CPOM was observed. Regression analysis was performed between density of periphyton and physico-chemical variables, which revealed that temperature, conductivity, alkalinity, CO2, TDS, CPOM and FPOM were found to have strong influence on the density and diversity of periphyton of Sahashradhara springs.International Journal of Environment Vol. 5 (1) 2016,  pp: 79-95

      Abstract: An experiment was conducted at the Agricultural Research Center of Al Ghab, General Commission for Scientific Agricultural Research (GCSAR), Syria, to evaluate the effect of some chemical application on the sugar losses reduction, and some quality traits in 2014/2015 season. Three slaked lime concentrations of 5, 10 and 15 percent, and three concentrations of calcium chloride of 2, 4, and 6%, and a mix of 5% slaked lime with 2% calcium chloride, beside the check (no treatment) (factor C). The second factor (D) was the storage durations of 6 days, and tow varieties (Factor V) were arranged as factorial experiment in RCBD with four replications. The varieties one of them was monogerm (Vico), while the other was multigerm (Reda), they were drilled in mid November, and storage roots were harvested late August. Weight percent loss and quality of beet samples such as sugar content, total soluble solids (TSS %), and purity% were determined throughout storage period. The results of analysis of variance ANOVA showed that effect of varieties was significant for TSS (brix %), sucrose%, root weight loss (P<0.05). All the studied traits were affected significantly (P<0.05) by storage duration. Chemical treatments had significant effect on all the studied traits (P<0.05), and the best treatment was with calcium chloride 6%. The percentage of variance confirmed that the most effective factor for the all studied traits was the storage period, followed by the varieties, and finally in a very low percent was the chemical treatments, because of that it is very urgent to send the harvested roots immediately to the factories to be processed within 24 hours, or treated with calcium chloride of 6% to preserve the sugar content as possible till manufacturing. Also the study concluded that the mutigerm variety Reda deteriorated less that the monogerm variety Vico, so Reda is recommended to be stored if necessary.International Journal of Environment Vol. 5 (1) 2016,  pp: 96-106

  • Impact of climatic variability on durum wheat (Triticum durum L.) yields
           in North Western of Algeria

    • Authors: Meterfi Baroudi, Wael El Zerey, Salaheddine Bachir Bouiadjra
      Pages: 107 - 120
      Abstract: In semi arid region of the South West of the Mediterranean basin, low rainfall, and thermal fluctuations cause water stress situations affecting at different levels, with varying intensities, the development of durum wheat yields. This work aims to study the major climatic factors that determine water environment of durum wheat in its reproductive period and assess their trend related to yields of the grain. Comparing diagrams of Bagnoul and Gaussen, established for two periods (1913-1937 and 1977-2014), highlighted an increase in the duration of the dry season due to rising temperatures, especially summer and a decrease in volume of the seasonal rainfall involving therefore water stress during the reproductive phase of cereal. The analysis of water regime in the past three decades, for the months of March, April and May, through the application of the approach of UNESCO-FAO, highlighted a very large variability in intensity of water stress during grain development period during the last years and also the tendency of the spring season months to be more drought. This reflects the complexity of the selection for yield components in this region. International Journal of Environment Vol. 5 (1) 2016,  pp: 107-120
