Gulf of Mexico (GOM) ecosystems are interconnected by numerous physical and biological processes. After the Deepwater Horizon (DWH) disaster, these ecological processes facilitated dispersal oil-spill toxicants or were damaged broken. A considerable portion post-DWH research focused on higher levels organization (i.e., populations, communities, ecosystems) spanning at least four environments (o...
The primary sources of energy for countries rich in oil and gas like Iran are petroleum, petroleum products, and natural gas resources. Foreign investments in the petroleum industry are concluded in the form of collaboration agreements, and the key to developing countries’ success in such agreements is technological learning. In the present study, we use mixed-method research to analyze differe...
Petroleum products are used for various reasons by human beings at homes, in manufacturing and petrochemical industries. The individuals most frequently exposed are those working in enterprises concerned with petrol and diesel, like petrol pumps. Chronic exposure to these compounds causes CNS depression and affects the kidney, liver, blood and systems. Hence, the present study was undertaken to...
Petroleum is a complex mixture of lipophilic chemicals, some of which are likely to be substrates for the microsomal mixed function oxygenases. Petroleum retailers, by virtue of their occupational exposure potential, are a group likely to receive relatively heavy exposure to petroleum products in comparison with the general public. Urinary thioether output may provide a simple, non-invasive tec...
Comparative assessment of potential human health impacts is a critical step in evaluating both chemical alternatives and existing products on the market. Most alternatives assessments are conducted on a chemical-by-chemical basis and it is seldom acknowledged that humans are exposed to complex products, not individual substances. Indeed, substances of Unknown or Variable composition, Complex re...
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...
There is a need for reliable and fast means of monitoring refining, conversion, and upgrading processes aiming to increase the yield of light distillates, and thus, reducing the oil barrel bottoms. By simultaneously utilizing the FID and mass selective detectors while splitting the column effluent in a controlled way, it is possible to obtain identical gas chromatograms and total ion chromatogr...
