Products Used To Clean Up Gulf Oil Spill May Have Made Things Worse, Study Finds
In the wake of the 2010 BP oil spill, cleanup crews dumped some 1.8 million gallons of chemical dispersants into the Gulf of Mexico. The substances were supposed to assist natural oil-eating bacteria in cleaning up the largest marine oil spill in history by breaking the oil into droplets the microbes could more easily consume. But the approach backfired, suggests a study published this month in the Proceedings of the National Academy of Sciences. "The dispersants did a great job in that they got the oil off the surface," University of Georgia marine scientist Samantha Joye, a co-author of the study, told the Asso...

Modelling the oil spill transport in inland waterways based on experimental study
Environ Pollut. 2021 May 28;284:117473. doi: 10.1016/j.envpol.2021.117473. Online ahead of print.ABSTRACTOil spills occurring either in oceans or inland waterways may cause serious economic losses and ecological damage. Previous studies pertaining to oil spills and their consequences are primarily based on marine environments, whereas few have focused on oil spills occurring in inland waterways characterised by pronounced flow advection transport effects, which differ from the marine environment. A generalised flume experiment is performed to investigate the spread and transport of oil spills, and the relationships between...

IJERPH, Vol. 19, Pages 9274: Numerical Study on the Influence of Model Uncertainties on the Transport of Underwater Spilled Oil
in Mu Oil pollution influences marine biology, ecology, and regional sustainable development capacity, but model uncertainties limit the ability of the numerical model to accurately predict the transport and fate of the underwater oil spill. Based on a three-dimensional underwater oil spill model validated by satellite images of the oil slick at the sea surface, the Penglai 19-3 oil spill accident in the Bohai Sea was simulated; in addition, several sensitivity experiments were set up to investigate the influence of model uncertainties in the background wind, current, start time of the oil spill, and spill site on the ...

A protocol for assessing the effectiveness of oil spill dispersants in stimulating the biodegradation of oil.
Abstract Dispersants are important tools in oil spill response. Taking advantage of the energy in even small waves, they disperse floating oil slicks into tiny droplets (<70 μm) that entrain in the water column and drift apart so that they do not re-agglomerate to re-form a floating slick. The dramatically increased surface area allows microbial access to much more of the oil, and diffusion and dilution lead to oil concentrations where natural background levels of biologically available oxygen, nitrogen, and phosphorus are sufficient for microbial growth and oil consumption. Dispersants are only used on subst...

Oil Spill Field Trial at Sea: Measurements of Benzene Exposure
Conclusions:The personal exposure to benzene downwind and close to the oil slick during spills of light crude oil was relatively high, with concentration levels approaching the occupational exposure limits for several participants. For bulk spill scenarios like in this study, cleanup should not be initiated the first 30 –60 min to allow for evaporation, while appropriate personal protective equipment should be used in continuous spills when working downwind and close to the oil slick.

Diagnostic ratios for the rapid evaluation of natural attenuation of heavy fuel oil pollution along shores.
Abstract Marine oil spills are typically followed by complex clean-up and monitoring operations of the shorelines affected. In this regard, determination of the changes in the chemical composition of the spilled product is crucial for evaluation purposes. The "GC-MS fingerprint" approach requires the identification of several key parameters in order to differentiate between weathering processes. In this context, we performed a 900-day study (eight sampling campaigns) of natural attenuation on a rocky shore affected by a heavy fuel oil spill. The residues coating the rocks were studied by extraction, separation and...

Bioherder Generated by Rhodococcus erythropolis as a Marine Oil Spill Treating Agent
In this study, the biosurfactant produced by Rhodococcus erythropolis M25 was evaluated and demonstrated as an effective herding agent. The impact of environmental and operational factors (e.g., temperature, herder dose, spilled oil amount, water salinity, and operation location) on its performance was investigated. A five-factor fractional design was applied to examine the importance of these factors and their impact on herding effectiveness and efficiency. The results of this study showed that higher temperature and a higher dose of herder could result in an increased oil slick thickness changing rate. Differences in wat...

Questions Remain Over U.S. Preparedness for the Next Oil Spill
In the midst of 2010 Deepwater Horizon oil spill, President Barack Obama’s administration declared a six-month moratorium on deepwater oil drilling. The spill was one of the country’s most devastating environmental disasters, and the freeze was intended to give the federal government time to assess what safety measures it had in place. But the moratorium passed, and drilling quickly resumed. Now, five years later, offshore oil drilling is more frequent and is done to even greater depth. Since the BP spill, the federal government has approved more than 20 ultra-deepwater drilling expeditions, according to the As...

Development of a statistical oil spill model for risk assessment.
Abstract To gain a better understanding of the impacts from potential risk sources, we developed an oil spill model using probabilistic method, which simulates numerous oil spill trajectories under varying environmental conditions. The statistical results were quantified from hypothetical oil spills under multiple scenarios, including area affected probability, mean oil slick thickness, and duration of water surface exposed to floating oil. The three sub-indices together with marine area vulnerability are merged to compute the composite index, characterizing the spatial distribution of risk degree. Integral of the...

Sensors, Vol. 17, Pages 1772: Hyperspectral and Radar Airborne Imagery over Controlled Release of Oil at Sea
bielle Remote sensing techniques are commonly used by Oil and Gas companies to monitor hydrocarbon on the ocean surface. The interest lies not only in exploration but also in the monitoring of the maritime environment. Occurrence of natural seeps on the sea surface is a key indicator of the presence of mature source rock in the subsurface. These natural seeps, as well as the oil slicks, are commonly detected using radar sensors but the addition of optical imagery can deliver extra information such as thickness and composition of the detected oil, which is critical for both exploration purposes and efficient cleanup ope...

Biosurfactant-modified palygorskite clay as solid-stabilizers for effective oil spill dispersion.
Abstract An effective and conventional remediation technique in marine oil spills is to apply chemical dispersants to emulsify oil slicks into small oil droplets. Still, the potential hazards of chemical dispersants onto the marine ecosystem have motivated the research for environmentally friendly alternative while keeping exceptional dispersion ability. Here, we showed that the mixture of palygorskite (PAL) and rhamnolipid (Rha) formed a biocompatible alternative to synthetic surfactants used for oil spill dispersion. The oil droplets dispersed by R-PAL presented a small average size and long-term stability, whic...

Metagenomic Insights Into the Mechanisms for Biodegradation of Polycyclic Aromatic Hydrocarbons in the Oil Supply Chain
Petroleum is a very complex and diverse organic mixture. Its composition depends on reservoir location and in situ conditions and changes once crude oil is spilled into the environment, making the characteristics associated with every spill unique. Polycyclic aromatic hydrocarbons (PAHs) are common components of the crude oil and constitute a group of persistent organic pollutants. Due to their highly hydrophobic, and their low solubility tend to accumulate in soil and sediment. The process by which oil is sourced and made available for use is referred to as the oil supply chain and involves three parts: (1) upstream, (2) ...
