The interaction between plants and microorganisms, which is the driving force behind the decontamination of petroleum hydrocarbon (PHC) contamination in phytoremediation technology, is poorly understood. Here, we aimed at characterizing the variations between plant compartments in the microbiome of two willow cultivars growing in contaminated soils. A field experiment was set-up at a former pet...

Carbon nanofibers (CNF) with diameters of 20-130 nm with different morphologies were obtained from a botanical hydrocarbon: Turpentine oil, using ferrocene as catalyst source and sulfur as a promoter by simple spray pyrolysis method at 1,000 °C. The influence of sulfur concentration on the morphology of the carbon nanofibers was investigated. SEM, TEM, Raman, TGA/DTA, and BET surface area were ...

Drilling operations of petroleum generate oily wastes. The disposal of a significant amount of oil-based drill muds has caused soil contamination and critical environmental impacts in the last decades.The current study aimed to investigate the potential of microbial remediation for an aged oil-based drilling waste and to monitor the fluctuation in microbial population throughout a ...

We performed a quantitative trait locus (QTL) analysis of epicuticular hydrocarbon variation in 1650 F(2) males from crosses of Baja California and mainland Mexico populations of Drosophila mojavensis cultured on two major host cacti. Principal component (PC) analysis revealed five PCs that accounted for 82% of the total epicuticular hydrocarbon variation. Courtship trials with mainland females...

Background: Polycyclic aromatic hydrocarbons (PAHs), which consist of fused conjugated aromatic rings, not only are toxic to humans and other living organisms, but will also pollute groundwater. These compounds can be point source or non-point source and are one of the most widespread organic pollutants. Some of them are suspected carcinogens and are linked to other health problems. This study ...

due to the location of a domestic, industrial and agricultural zone near the caspian sea, this water body has long been under pressure and environmental threat. as a result of development of oil production activities in caspian region, such as oil exploration and extraction, a large volume of oil related pollutants is released annually into this important water body. considering the fact that h...

Hydrocarbon aspiration causes acute lung injury, which may lead to acute respiratory distress syndrome. Surfactant has been shown to be beneficial in experimentally-induced hydrocarbon-associated acute respiratory distress syndrome. However, there has not been a clinical study evaluating the effect of surfactant application on hydrocarbon aspiration in humans. We report a 17-month-old boy with ...

Sawdust evaluation in bioremediation of PMS hydrocarbon polluted agricultural soil was carried out. The effect of different parameters; total petroleum hydrocarbon, dehydrogenase activity, optical density and pH on bioremediation performance were evaluated. Studied parameters such as microbial dynamics and hydrocarbon removal were found to be higher in sawdust amended system and differed signif...

The drilling time data of gas logging are used to calculate drilling time ratio of the reservoir, and the total hydrocarbon data are used to calculate hydrocarbon contrast coefficient and to establish the drilling time ratio--hydrocarbon contrast coefficient crossplot. The standards of distinguishing the boundaries of hydrocarbon zones, hydrocarbonaceous water layers and dry layers are determin...
