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}

However, a combination of crude implements, inadequate artificial fertilizers, all add to the tedious environmental setting in which farming is carried out. This study attempts to show how agroforestry practice yields much needed benefits in the study area. The study used multistage sampling; three zones in the state, Jigawa northwest, Jigawa northeast and Jigawa south. Out of each zone, 3 Local Government LGA were selected, out of which 50 respondents were purposively targeted from each community making an overall total 450 respondents. Descriptive statistics using mean, percentages and use of table and figures were used for the analysis. The results show that the benefits derived by the respondents are fertility maintenance 83%, fodder for livestock 81%, Micro-climate has moderation 66%. Increasingly as in other parts northern Nigeria, results show a number of tree species noted for their medicinal value are becoming extinct due to the pressures of demand both in forests and on farms. The study recommends boosting further research to conserve these disappearing species from extinction.","PeriodicalId":14546,"journal":{"name":"IOSR Journal of Environmental Science, Toxicology and Food Technology","volume":"51 1","pages":"31-38"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80174613","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}
