Microbial bioremediation of petroleum wastewater by phenol-degrading-bacteria holds promise in circumventing the issue of petroleum-spill related pollution. Herein, biodegradation of petroleum wastewater samples collected from oil refinery site was carried out in a fluidized bed bioreactor by Ca-alginate immobilized biomass of phenol-degrading strains of Bacillus cereus (AKG1 MTCC9817 and AKG2 ...

The most usual type of petroleum mulch, which has been successfully used to combat desertification in large areain Iran for more than thirty years, is produced by heavy residue petroleum cuts. The petroleum mulch consists of awide range of different heavy hydrocarbons such as Polycyclic Aromatic Hydrocarbons (PAHs). PAHs are present atlow level in petroleum mulch, where there is contact with wa...

the petroleum potential of the seyahou (ordovician) and sarchahan (lower silurian) formations in northern bandar abbas has not been investigated sufficiently. these sediments crop out as thinly laminated shales and are about 100 meters thick. a number of thirty-five selected samples were subjected to rock-eval pyrolysis followed by transmitted, reflected and uv light microscopy together with cl...

To investigate the antiarrthritic activity of petroleum-ether extract of Portulaca oleracea. The petroleum-ether extract of Portulaca oleracea was subjected to preliminary phytochemical screening. Acute toxicity studies were carried out in Male Wistar rats and anti-arthritic activity by Fruends adjuant arthritis model. Phytochemical evaluation revealed the presence of alkaloids, tannins, flavon...

Response issued draft vapor intrusion guidance (EPA, 2002), which specifically states that it is not recommended for Subtitle I underground storage tank (UST) sites. EPA's Office of Underground Storage Tanks (OUST) is thus currently developing guidance to address petroleum vapor intrusion (PVI) at UST sites. OUST has consulted on several occasions with experts in the field of vapor intrusion an...
