Subsoil TPH contamination in two oil pipeline pumping stations and one pipeline right-of-way in north Mexico.

Summary of "Subsoil TPH contamination in two oil pipeline pumping stations and one pipeline right-of-way in north Mexico."

This investigation deals with the characterization carried out in zones around two pipeline pumping stations and one pipeline right-of-way in the north of Mexico. In particular those areas where contamination was evaluated: (a) south area of the separation ditch in the Avalos station, (b) the area between the separation ditch at the Avalos station, (c) km 194+420 of the Moctuzma station, and (d) km 286+900 in the Candelaria station. Results of this investigation showed that only four samples showed TPH values higher than the Mexican limit for 2004: AVA 1B, with 21,191mgkg(-1); AVA 1C, with 9348mgkg(-1); AVA 2B, with 13,970mgkg(-1); and MOC 2A, with 4108mgkg(-1).None of the sampled points showed the presence of PAHs at values higher than those found in the Mexican or American legislations. PAH were detected in the range of 0.0004 and 13.05mgkg(-1).It is suggested to implement surfactant soil washing as a remediation technique for the approximately 600m(3) that need to be treated.

Disabling osteochondrodysplasia with OSTEOSCLEROSIS, cone-shaped METAPHYSIS, and shortening of the DIAPHYSIS. It is endemic in parts of Siberia and northern China. Mineral deficiencies (e.g., selenium, iodine), fungal cereal contamination, and water contamination may be contributing factors in its etiology.

Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.
