The soil samples were collected from cultivated area that is not affected by spill and crude oil polluted site both in Bodo city in Gokana Local Government Area of River State and were taken to Campus II Delta State University, Abraka, Delta State. Four selected vital crops were sown on these soils to determine the plant growth response due to the presence of crude oil contamination. The unpolluted soil was used as a control as compared to the polluted one. The parameters analyzed were soil moisture content, pH, Electrical conductivity (E.C), total hydrocarbon content (THC), total organic carbon (TOC), total nitrogen, phosphorus, zinc, lead, cadmium, nickel, chromium, sand, silt and clay. The study revealed that there were adverse effects of crude oil pollution on soil nutrients, fertility as well as plant growth and production. It was also observed that the polluted agricultural land had high concentration of zinc, lead, cadmium and Chromium that are above the limit set in the National Standard for heavy metal pollution on soil. The people’s livelihood as well as their food security is a function of the healthy state of the soil for plant production for sustainability. Therefore, it is recommended that the UNEP Environmental Assessment Report on Ogoni land should be implemented with immediate effect to ameliorate the native effects of crude oil spill on vital food crops of the Ogoni people.","PeriodicalId":119603,"journal":{"name":"Nigerian Journal of Science and Environment","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128601837","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 mechanism behind this phenomenon is an oxygen-dependent reaction involving substrates generally termed luciferin, which is catalyzed by one or more of an assortment of unrelated enzyme called luciferases. The history of bioluminescence in fungi can be traced far back to 382 B.C. when it was first noted by Aristotle in his early writings. It is the nature of bioluminescent mushrooms to emit a greenish light at certain stages in their life cycle and this light has a maximum wavelength range of 520-530 nm. Luminescence in mushroom has been hypothesized to attract invertebrates that aids in spore dispersal and testing for pollutants (ions of mercury) in water supply. The metabolites from luminescent mushrooms are effectively bioactive in anti-moulds, anti-bacteria, anti-virus, especially in inhibiting the growth of cancer cell and very useful in areas of biology, biotechnology and medicine as luminescent markers for developing new luminescent microanalysis methods. Luminescent mushroom is a novel area of research in the world which is beneficial to mankind especially with regards to environmental pollution monitoring and biomedical applications. Bioluminescence in fungi is a beautiful phenomenon to observe which should be of interest to Scientists of all endeavors.","PeriodicalId":119603,"journal":{"name":"Nigerian Journal of Science and Environment","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126085705","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}

Nigeria like many developing countries, still do not have reliable data base for many of these sources for now. So here the study propose that a theoretical approach of estimating the amount of carbon dioxide (CO2) in kg that is emitted by n-litres of fuel which is a modification of the reference approach, can be a starting point in planning for the inventory of CO2 emission in Nigeria. The method is demonstrated to obtain an estimate of the CO2 emission in Nigeria from 2000 to 2014 from only the three major petroleum products which are Premium Motor Spirit (PMS), Diesel (AGO) and House Hold Kerosene (HHK) that can be obtained from government official agency. The results depict fluctuation in the CO2 emission in Nigeria in the 15 years period in agreement with the projection in the literature. The results also shown that for the total emission of CO2 in this period, the highest emission was from PMS with 73.60%, followed by AGO with 15.60% and the least emitter is HHK with 10.80%.

The experiment was carried out at the Forestry and Wildlife Research Farm, Delta State University, Asaba Campus. 27 breeder snails each of A. marginata and A. achatina species with average weight of 300 and 280 g respectively were purchased from the University of Ibadan Research Farm in Oyo State and were taken care of intensively. The breeder snails used for the experiment were distributed randomly in baskets filled with loamy soil to the depth of 10-15 cm; they were fed with different diets- pawpaw leaf, water leaf, cabbages and water melon, for 12 weeks. The parameters measured were weight, length and width of eggs, weight of hatchling, length of hatchling and aperture length of hatchling. The results of the experiment showed that there were significant differences (p<0.05) between the species-A. marginata and A. achatina in parameters such as weight of eggs, width of eggs, weight of hatchlings, length of hatchlings and the aperture length of hatchlings.

Also, 92.6% agreed that customary laws were used to conserve flora and fauna in the area, whereas, 97% agreed that applying appropriate sanctions on defaulters will help conservation.

Each group contains six birds each. Each bird was weighed and cyanide was administered according to their body weight every morning. The levels of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) was determined calorimetrically. The levels of lipid peroxidation, superoxide dismutase (SOD), catalase and glutathione peroxidase was also determined in the liver and organs of the birds by standard biochemical procedures. The results obtained showed a significant increase (P 0.05) in AST and ALT activity was recorded in Group C and D when compared with group B (cyanide control); similar result was recorded in alkaline phosphatase (ALP) activities. A significant decrease in lipid peroxidation level was also recorded in the liver and kidney of group C and D birds when compared with group B birds.

The experiment was carried out in a randomized complete block design at the experimental screen house of Plant Biology Biotechnology, University of Benin, for 15 weeks. The results (expressed in ppm or mg/l) showed that pH, Na, K, Ca, Mg, Fe, Zn, Mn, Cu, electrical conductivity (1067µg/cm), TDS (0.41 ppm), BOD (2.6 ppm), TSS (0.38 ppm) and chlorides (561.22 ppm) were within the accepted standards of WHO and NESREA. They showed that ballast water would be suitable for watering plants. The water enhanced the growth of the test plant. Significant difference was not observed at 5% level (P < 0.05) in the parameters tested for C. frutescens. Temperature increase was observed as the factor because the control plants cultivated outside the screen house flowered and fruited. Since high electrical conductivity and alkalinity observed in the ballast is an indication of toxicity, further study is therefore recommended to access the metal uptake and cytotoxicity of the test plant to know if the plant treated with ballast water would be suitable for consumption.","PeriodicalId":119603,"journal":{"name":"Nigerian Journal of Science and Environment","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133213140","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}
