A major fraction of the petroleum hydrocarbons discharged during the 2010 Macondo oil spill became associated with and sank to the seafloor as marine snow flocs. This sedimentation pulse induced the development of distinct bacterial communities. Between May 2010 and July 2011, full-length 16S rRNA gene clone libraries demonstrated bacterial community succession in oil-polluted sediment samples ...
The potential for use of alternatives to total petroleum hydrocarbons (TPH) for remediation purposes was examined specifically for JP-4 fuel. The study objective was to determine the scientific basis for use of fuel constituents other than TPH in establishing soil cleanup standards at JP-4-contaminated sites. The general bases for TPH soil cleanup standards or goals were characterized. Problems...
In the present study, juvenile sea bass were exposed for 48 and 96 h to an Arabian light crude oil and their responses were assessed at the molecular and physiological levels. The aim of the study was therefore to assess (i) the short term effects of crude oil exposure by the measurement of several molecular biomarkers, (ii) the consequences of this short term exposure on fish health by using g...
In October 2007, a light crude oil spill took place in the off shore Kab121 oil well, 32 km north of the mouth of the Grijalva River, Tabasco, Mexico. In order to estimate the possible effects of oil spill on the biota in the area surrounding the spilled well, the level of different fractions of petroleum hydrocarbons were measured in fish, as well as the concentration of some chlorinated hydro...
Chemical spills and accidents contaminate the environment and disrupt societies and economies around the globe. In the United States there were approximately 172,000 chemical spills that affected US waterbodies from 2004 to 2014. More than 8000 of these spills involved non-petroleum-related chemicals. Traditional emergency responses or incident command structures (ICSs) that respond to chemical...
Abstract In 2019, the International Oil Spill Conference (IOSC) passed a significant milestone in turning 50 years old. Springing from aftermath both Torrey Canyon and Santa Barbara oil spills, New York City hosted first IOSC 1969, attracting attention participation of growing body practitioners particular form emergency response. Bringing together world leaders spill prevention, preparedness, ...
process mediated by or involving microorganisms in which a product of economic value is obtained is called fermentation (Casida, Jr., 1968). The terms industrial microbiology and fermentation are virtually synonymous in their scope, objectives and activities. The microbial product may be microbial cells (living or dead), microbial biomass, and components of microbial cells, intracellular or ext...
The demand for technological and industrial change has become heavily dependent on the availability use of petroleum products as a source energy socio-economic development. Notwithstanding, petrochemical are strongly related to global economic activities, their extensive distribution, refining processes, final routes into environment pose threat human health ecosystem. Additional environmental ...
Past petroleum-extraction activities in Ecuador have contaminated its Amazon region. To assess the environmental impact attributed to remediation regarding cleanup of these oil spills, two scenarios were studied according Life Cycle Analysis methodology: (1) No-action, which means leave contamination place without any further action and (2) Environmental remediation, where environmental-load re...
Nigeria had relied solely on her oil wealth at the expense of all other naturally endowed agricultural and enormous mineral resources that abound every landscape of the country. The worldwide economic melt-down that was experienced by the third quarter of 2008 in the United States of America coupled with the slide in foreign earning from crude oil export revenue at the international market, lea...
