In the title compound, 4-[3-(3-sulfonato-pyridin-1-ium-4-yl)prop-yl]pyridin-1-ium-3-sulfonate, C(13)H(14)N(2)O(6)S(2), the mol-ecule is zwitterionic, with the sulfonic acid proton transfered to the basic pyridine N atom. Also, the structure adopts a butterfly-like conformation with the sulfonate groups on opposite sides of the 'wings'. The dihedral angle between the two pyridinium rings is 83.5...

Workers in the petroleum industry are potentially exposed to a variety of petrochemicals, including benzene or benzene-containing liquids. Although a large number of studies of petroleum workers have been conducted to examine leukemia and other cancer risks, few existing studies have investigated cell-type-specific leukemias. One of the major reasons for the lack of cell-type-specific analysis ...

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...

In the rubber industry, plasticizers for rubber compounds mainly consist of petroleum derivatives. Consequently, the rubber industry is in constant competition with many petroleum consumers. This competition places an economic strain on rubber companies such as HEXPOL RUBBER COMPOUNDING L.L.C. In order to alleviate this strain, natural oil alternatives to petroleum plasticizers are of novel res...

There are many challenges associated with development of offshore petroleum fields. Subsea production facilities are increasingly used in the petroleum industry as the technology has matured and quality increased. The use of subsea technology has advantages as well as challenges. Based on a literature review this paper identifies some if the development challenges related to the design and oper...

The title compound {systematic name: poly[[μ(7)-(2R)-2-amino-3-sulfonato-propano-ato]disodium]}, [Na(2)(C(3)H(5)NO(5)S)](n), was obtained through solvent-thermal reaction of l-cysteic acid and aqueous sodium hydroxide. The monomer consists of two Na(+) cations that are coordinated to the deprotonated amino acid. The latter acts as donor utilizing all available coordination sites, viz. the amino...

Aquamicrobium defluvii W13Z1 was isolated from petroleum-contaminated drill cuttings from the Bohai Sea and could degrade petroleum hydrocarbon with 5% NaCl at 15°C. Here, we present the 4.8-Mb draft genome sequence of this strain, which may provide useful information about the mechanism of petroleum degradation in drill cuttings.

BACKGROUND In general, organic solvents are inhibiting many physiological enzymes and alter the behavioural functions, but the available scientific knowledge on laboratory solvent induced organ specific toxins are very limited. Hence, the present study was planned to determine the sub-chronic toxic effects of petroleum ether (boiling point 40-60°C), a laboratory solvent in Sprague-Dawley (SD) r...
