The demand for crude oil can’t be denied as it is a major source of energy (production of electricity, cooking gas, and facilitating transportation) and raw materials for various petroleum. Lack of mutagenic activity of crude and refined oils in the De Lora S () Interaction between polycyclic aromatic hydrocarbons, crude oil and oil dispersants in the Salmonella mutagenesis assay.

The variation of antimicrobial activity of present study might be due to distribution of antimicrobial substances, which varied from fraction to fraction of the crude Size: KB. The material covered by Microbiologically Influenced Corrosion: An Engineering Insight will be of benefit to professional and consultant engineers in power generating, oil and gas, marine, and.
ENVIRONMENTAL RESEA () The Mutagenicity of a Prudhoe Bay Crude Oil and Its Residues from an Experimental in Situ Burn' E. P. SHEPPARD, R. A. WELLS, AND P. E. GEORGHIOU3 Department of Chemistry, Memorial University of Newfoundland, St. John's, Newfoundland, AM 3X7, Canada Received Septem Fresh and weathered Prudhoe Bay crude oil Cited by: 7. To examine whether the antimicrobial activity of the present EOP sample was directly associated with DNA damage, the genotoxic potential of the crude oil was evaluated by SMART, performed on wing cells of D. melanosgaster, using ST and HB crosses (the latter is characterized by high levels of CYP, rendering it highly sensitive to promutagens and procarcinogens).Cited by: 9. Figure 9 indicates that the mutagenic activity of refinery particulate extracts is positively associated with the levels of oil and grease in the sample (r = ). Table 6. Mean and range of mutagenic activity (revertants per mg) of residues extracted from refinery effluents, and estimates of the rate of discharge of this material from the Cited by: 3. Asphalt base contain little paraffin wax and an asphaltic residue .The sulfur, oxygen and nitrogen contents are often relatively higher in comparison with paraffin base crudes, which contain little or no asphaltic materials. Mixed crude oil contains considerable amount of oxides of nitrogen and asphalt .Cited by:
Crude oil bioremediation of soils is limited by the bacteria activity in degrading the spills hydrocarbons. Native crude oil degrading bacteria were isolated from different crude oil polluted soils. Evaluation of the Relationship between PAH Content and Mutagenic Activity of Fumes from Roofing and Paving Asphalts and Coal Tar Pitch. crude oil source, or temperature at which the fume was generated correlated with mutagenic activity. The fume condensates were tested for mutagenic activity using a modified Ames by: Crude Oil. In their review of the carcinogenicity of petroleum hydrocarbons, Bingham et al. 3 cited several of the early researchers' work () on the carcinogenicity of crude-oil fractions from various sources when applied to the skin of mice. The distillate fractions in the –°C range were later found to be more carcinogenic than whole crude oil in mice and rabbits. Fractions 1, 3, and 4 were tested for embryotoxic and teratogenic activity on a weight-equivalent basis, i.e., 1 mg-eq of an Prudhoe Bay crude oil was obtained from Atlantic Richfield (Cherry Point Refinery, Wash.), and the fuel oil No. 2 was obtained from a local supplier of Imperial Oil Cited by:
