The analysis covers data for the period 1901–2010 with a spatial resolution of 0.5°x°0.5° of geographic longitude and latitude (GPCC data). The data is analysed in monthly and calendar year profiles. The periodical nature of precipitation is assessed and the trends in climate changes calculated. The characteristics of trend in climate changes are described by linear equations with indicated boundary values of coefficients determined at a 5% significance level. The analyses discussed confirm spatial and temporal variability of precipitation in the key river catchment areas in India, feeding the country's surface and underground water resources. The statistics contained in this study demonstrate the regional nature of water supply, indicate the need to complete regional analyses of temporal and spatial variations in the volumes of water feeding Indian resources, and confirm that regional and local plans must be developed to adapt to climate change, based on the accepted scenarios aimed to compensate climate change effects.","PeriodicalId":14546,"journal":{"name":"IOSR Journal of Environmental Science, Toxicology and Food Technology","volume":"12 1","pages":"51-73"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79712886","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The samples were obtained from the first outlet from the well that was available for the collection of the water by the users. Six of the wells grew numerous types of bacteria including coliforms and non-fermentative organisms. Two wells grew Salmonella and Shigella species respectively, while a third was recognized for the very big number of CFUs growing from the sample obtained. The three wells that did not grow organisms were obtained from a central tank in each building that was regularly chlorinated and from which the users collected their water supply, when needed. The results show that the substantial contamination obtained, prohibits the use of well-water in the region for any use, without proper treatment to avoid undesired medical consequences. Further studies and intervention of the public health authorities are needed, as the results of this study indicate that this problem seems to be of a bigger magnitude than presumed.","PeriodicalId":14546,"journal":{"name":"IOSR Journal of Environmental Science, Toxicology and Food Technology","volume":"72 1","pages":"81-85"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73880752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Physico-chemical parameters such as pH, total organic carbon (%TOC), total organic matter (%TOM), total nitrogen (TN), available phosphorus (P), available potassium (K) and total petroleum hydrocarbon (TPH) of the contaminated soil and soil amended with saw dust and rice bran were monitored during the study period. Homogenized sterilized soil (700g) each was amended with 150 g of saw dust, rice bran and inoculated with P.pulmonariusspawn,to establish A (soil + saw dust + rice bran + P.pulmonarius), B (soil + rice bran + P.pulmonarius), C (soil + saw dust + P.pulmonarius) and D (soil + saw dust + rice bran) experimental set-up. The experiment was allowed to run for 60 days with periodic sampling every 15 days intervals for analysis. The results revealed a sharp decrease in TPH concentration after 15 days, which progressively decreased further over the subsequent sampling intervals; with a corresponding increase in the removal rate of nitrogen, phosphorus and potassium. Set-up A and D emerged as the maximum and minimum for the removal of TPH components at the end of the bioremediation process as illustrated in the order: A (90.12%) > B (77.42%) > C (72.20%) > D (9.98%). It was observed that the saw dust and rice bran blend had sufficient amounts of nitrogen, phosphorus and potassium (NPK) to sustain biodegradation of crude oil components in the contaminated soil. Biodegradation of the hydrocarbon components of the crude oil was confirmed using gas chromatography and reduction of crude fractions with carbon atoms ranging from C10-C40 was observed. This study showed that P.pulmonarius is effective at decontaminating crude oil polluted soil.","PeriodicalId":14546,"journal":{"name":"IOSR Journal of Environmental Science, Toxicology and Food Technology","volume":"87 1","pages":"122-128"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76842739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present objective is to determine the analytical characteristics of different substrates generated in the State of Tabasco, and to determine theoretically its potential in obtaining biogas, thermal and electrical energy. The analytical results, indicate that pork and cow excreta, and the water lily, have the highest SVT content, with 82.82 ± 1.33%, 81.41 ± 1.43% and 81.19 ± 2.52% respectively. The theoretical biogas production was higher in pig substrates (20.21 m 3 d -1 ), chicken (15.73 m 3 d -1 ), dog (11.57 m 3 d -1 ) and lamb (9.25 m 3 d -1 ). In heat capacity, the chicken and pork substrates, present the highest theoretical capacity in substitution of LP gas with 5.02 and 6.45 kg d -1 , respectively. Finally, the theoretical values of electricity generation were presented in the substrate chicken, pork and lamb, with 2,156.71, 2,404.37 and 2,475.91 kW year -1 , respectively.

Based on biochemical, microbiological, and sensorial analysis, several indices were used to monitor the product quality over 60 days of refrigerated storage at 2 ±1°C. A different pattern of amine changes occurred following salting and smoking. Except for (his) and (spm); all others amines including cadaverine increased in cold smoked fillets throughout storage. The indices of atherogenicity (IA) and of thrombogenicity (IT) with values of 1.68 and 1.67 respectively, did not show a significant change during storage suggesting a stability of the fatty acids profile. However microbiological analysis limited the shelf life of thin-lipped grey mullet fillets up to 30 days of refrigerated storage. Increase of the microbial load was accompanied by a concomitant and significant (P < 0.05) rise of trimethylamine (TMA-N); volatile basic nitrogen (TVB-N) and change in sarcoplasmic and myofibrillar protein profiles in smoked fish fillet. The Ki and G values calculated from ATP-related compounds showed different pattern of change. Analysis of polycyclic aromatic hydrocarbons (PAHs) of fresh and smoked fillets showed undetectable level of benzo(a)pyrene (BaP) and the sum of PAHs (2.45 ng g −1 ) was far lower than the limit of acceptability. Data submitted to principal component analysis (PCA) showed that cold smoking process was positively correlated with results of TVB-N, TMA-N and HPX.","PeriodicalId":14546,"journal":{"name":"IOSR Journal of Environmental Science, Toxicology and Food Technology","volume":"12 1","pages":"24-37"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82224473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
