in this research the effects of crude oil on morphological and physiological characterization ofthe cyanobacterium microchaete tenera isc13 were investigated. isolated cyanobacterium treated with different oil concentrations (control, 1, 2.5, 5 and 7%) in carbonless bg110 medium. morphological characteristics such as morphology of filament, cellular shapes and sizes, relative position of hetero...
BACKGROUND Despite the growing awareness of the necessity of a sustainable development, the global economy continues to depend largely on the consumption of non-renewable energy resources. One such energy resource is fossil oil extracted from the seabed at offshore oil platforms. This type of oil production causes continuous environmental pollution from drilling waste, discharge of large amount...
The coastal zone, with their vast resources of food, energy, and minerals, not only are composed of various fragile ecosystems, but are scenes of a variety of often conflicting uses. At present, the uncontrolled development of the coastal zone and the almost haphazard exploitation of their natural resources threaten to turn the promise of economic prosperity into an environmental nightmare that...
Soil bacteria play a major role in ecological and biodegradable function processes in oil-contaminated soils. Here, we assessed the bacterial diversity and changes therein in oil-contaminated soils exposed to different periods of oil pollution using 454 pyrosequencing of 16S rRNA genes. No less than 24,953 valid reads and 6246 operational taxonomic units (OTUs) were obtained from all five studi...
The American oil shale industry is on the threshold of commercial industrial development. Potential occupational hazards include shalosis or oil shale pneumoconiosis, dermatoses, cancer of the skin, lung, and possibly other sites, and accidents. Air, water, and solid waste pollution problems are complicated by the aridity of the Green River oil shale formation located in Utah, Colorado, and Wyo...
An operational model for the prediction of circulation and transport of oil spill in the Black Sea is presented. The hydrodynamic block is developed on the basis of the DieCAST high-resolution low-dissipative model adapted to the Black Sea. The oil spill transport block is constructed on the basis of the random walk approach, which allows predicting motion of individual particles, the assembly ...
Taiwan has implemented a floating oil-price mechanism since 2007, which is aimed at connecting the domestic oil price with the international oil price. Given that the consumers’ behavior may change once the price truly responds to its cost and the air quality may consequently be improved, this study investigates the effect of oil price on the concentration of 7 air pollutants, taking the adopti...
Acute and chronic pollution of environments with crude oil does not bode well for biota living within the vicinity of polluted environments. This is due to environmental and public health concerns on the negative impact of crude oil pollution on living organisms. Enhancing microbial activities by adding nutrients and other amendments had proved effective in pollutant removal during bioremediati...
The expansion of oil palm cultivation in Indonesia has been driven by a strong world demand for food especially fats and oils. Commencing in the island of Sumatra, it spread out to other island like Kalimantan, Sulawesi and Irian but not to the island of Bali which was already well developed. The role of palm oil in developing remote inland regions and improving the standard of living of rural ...
Contamination of the environment in Kuwait occurred in 1990-1991 during the Iraqi invasion and due to explosion of more than 700 oil wells. Oil contamination caused serious damage to the environment. This study was conducted to estimate the extent and volume of contaminated soil by using remote sensing, GIS application and field survey.. A map of the area was developed by GIS showing four types...
