A physician-based case-control study of non-melanoma skin cancer was conducted to test the hypothesis that employment in the petroleum industry increased the risk of basal cell carcinoma (BCC), squamous cell carcinoma (SCC), or both (BCC+SCC). Other potential risk factors were also investigated. There were 174 cases of BCC, 59 cases of SCC, 72 cases of both and 229 controls completing a self-ad...

Continued use of petroleum sourced fuels is now widely recognized as unsustainable because of depleting supplies and the contribution of these fuels to the accumulation of carbon dioxide in the environment. Renewable, carbon neutral, transport fuels are necessary for environmental and economic sustainability. Biodiesel derived from oil crops is a potential renewable and carbon neutral alternati...

Use of chemical criteria in assessing the potential for adverse toxic effects in contaminated sites can under or overestimate the necessary level of site cleanup required. The use of ecotoxicity testing provides a more direct assessment of adverse environmental impact. A multi-trophic level soil ecotoxicity assessment was done on soil contaminated with crude oil distilled into five different fr...

Recently, utilization of renewable resources to replace petroleum as a primary feedstock for liquid fuels, chemicals and materials has become a topic of interest around the world. It is intriguing due to rising oil prices, the negative effects of petroleum on the environment and the advantages of renewable resources, such as their abundance and sustainability. Herein, the possibilities for biob...

The aim of the research was to compare the effects of various petroleum products, biodiesel, diesel oil, fuel oil and unleaded petrol on soil dehydrogenases, and to evaluate biostimulation with compost and urea in the restoration of homeostasis of the soil contaminated with these products. The obtained results allowed for defining the weight of dehydrogenases in monitoring of the environment su...

Petroleum coke is a valuable and potential source for clean energy storage if it could be modified legitimately and facilely. In the present study, porous carbon with high surface area and abundant oxygen-containing groups was prepared from petroleum coke by chemical activation and modification processes. The as-prepared carbon exhibits a high surface area (1129 m(2) · g(-1)) and stable microgr...

Since the realization that global sustainability depends on renewable sources of materials and energy, there has been an ever-increasing need to develop bio-based polymers that are able to replace petroleum-based polymers. Research in this field has shown strong potential in generating high-performance functionalized polymers from plant biomass. With the anticipated large-scale production of li...

The investigation was carried out to determine qualitatively the phytoconstituents from the methanol and petroleum ether extracts of Drynaria quercifolia Linn. rhizome. Among the phytochemical screening of these extract, methanolic extract showed high number of constituents like alcohol, carbohydrates, phytosterols, phenols, tannins, flavonoids, proteins and aminoacids, steroids, saponins, chol...

The present study aims qualitative screening of the phytochemicals present in the peel of Amorphophallus paeoniifolius (Jimikand/ Suran) for its utilization as a potential therapeutic. The peel extract was prepared by dissolving dried peel powder in solvents like water, methanol, petroleum ether, and chloroform and concentrated using a rotary vacuum evaporator. The standard qualitative test for...

The similarities and differences in reservoir engineering in the geothermal and petroleum industries are not familiar to many. This unfamiliarity frequently leads to aberrant perception of the risks and rewards of geothermal development in the minds of developers and financiers who are accustomed to the petroleum industry but are new to geothermal. This paper is a comparative survey of the stat...
