Effects of Crude Oil, Dispersant, and Oil-Dispersant Mixtures on Human Fecal Microbiota in an In Vitro Culture System
The Deepwater Horizon oil spill of 2010 raised concerns that dispersant and dispersed oil, as well as crude oil itself, could contaminate shellfish and seafood habitats with hazardous residues that had potential implications for human health and the ecosystem. However, little is known about the effects of crude oil and dispersant on the human fecal microbiota. The aim of this research was to ev...
متن کاملComparative toxicity of oil, dispersant, and oil plus dispersant to several marine species.
Dispersants are a preapproved chemical response agent for oil spills off portions of the U.S. coastline, including the Texas-Louisiana coast. However, questions persist regarding potential environmental risks of dispersant applications in nearshore regions (within three nautical miles of the shoreline) that support dense populations of marine organisms and are prone to spills resulting from hum...
متن کاملStability Research on the Effect of Oil Spill Dispersant I-Separation Char- acteristics of Oil Spill Dispersant
With the continuous research and development of the low-toxic and high-efficiency oil spill dispersants (OSDs), there are an increasing number of evaluation methods for the effect of the OSDs. Currently, the majority of the OSDs effect evaluation is related with the testing of the emulsification in the laboratory, while the stability researches on the OSDs effect are still few. In this paper, t...
متن کاملDynamics of the hydrocarbon-degrading Cycloclasticus bacteria during mesocosm-simulated oil spills.
We used catalysed reported deposition - fluorescence in situ hybridization (CARD-FISH) to analyse changes in the abundance of the bacterial groups Alphaproteobacteria, Gammaproteobacteria and Bacteroidetes, and of hydrocarbon-degrading Cycloclasticus bacteria in mesocosms that had received polycyclic aromatic hydrocarbons (PAHs) additions. The effects of PAHs were assessed under four contrastin...
متن کاملPenicillin in oil-wax mixtures.
One of the main disadvantages of penicillin as a chemotherapeutic agent is that the kidney is able to eliminate it from the blood in a relatively short time, making it necessary that injections be repeated fairly frequently in order to maintain a therapeutic blood level for a long period. This is, of course, most undesirable from the patient's point of view and many workers have attempted to fi...
