An insight into the current oil spills and on-site bioremediation approaches to contaminated sites in Nigeria.
Abstract Land oil spills in Nigeria have a long history of contaminating the soil, groundwater, vegetation, and streams with spill extension being the primary of numerous ordeals. These have left the host communities of oil fields and pipelines in crucial need of soil rehabilitation. Thus, this review provides insights into the current state of land oil spills and the effectiveness of on-site remediation approaches across communities. A total of 44 incidents of land oil spills of ≥ 500 bbl, amounting to 53,631 bbl between 2011 and 2019, was recorded by the Shell Petroleum Development Company, which primarily att...

Sorbent-based devices for the removal of spilled oil from water: a review
Environ Sci Pollut Res Int. 2021 Apr 12. doi: 10.1007/s11356-021-13775-z. Online ahead of print.ABSTRACTAlways, oil spills do cause serious and dire consequences for the environment, nature, and society that it consumes much time and socio-economic resources to overcome such consequences. Oil spills, hence, posed a big challenge in searching the advanced technologies and devices to recover spilled oil rapidly and efficiently. Indeed, sorbents have been found to play an extremely critical role in the spilled-oil remediation processes. Recently, a large number of various advanced sorbents and sorbent-based oil-collecting dev...

Adaptation of metabolite leakiness leads to symbiotic chemical exchange and to a resilient microbial ecosystem
by Jumpei F. Yamagishi, Nen Saito, Kunihiko Kaneko Microbial communities display remarkable diversity, facilitated by the secretion of chemicals that can create new niches. However, it is unclear why cells often secrete even essential metabolites after evolution. Based on theoretical results indicating that cells can enhance their own growth rate by leaking even essential metabolites, we show that such “leaker” cells can establish an asymmetric form of mutualism with “consumer” cells that consume the leaked chemicals: the consumer cells benefit from the uptake of the secreted metabolites, while the leaker cells al...

Houston Ship Channel Reopened to Limited Traffic
(GALVESTON, Texas) — The Coast Guard partially reopened one of the nation’s busiest seaports to ship traffic Tuesday, three days after a collision between a barge and a ship spilled up to 170,000 gallons of tar-like oil into the waters south of Houston. Authorities said ships were being allowed through the Houston Ship Channel after their assessment teams deemed it was clear enough for passage. More than 100 ships on both sides of the channel were awaiting the reopening. “The cleanup operations progress is to the point that there is minimal danger of contamination to the commercial maritime traffic and allowi...

Impact of dispersant on crude oil content of airborne fine particulate matter emitted from seawater after an oil spill.
Abstract Inhalation of PM2.5, particles with an aerodynamic diameter <2.5 μm, from sea spray after crude oil spills could present serious health concerns. The addition of dispersants to effectively spread the crude oil throughout the water column has been practiced in recent years. Here, we investigated the possibility of an increase in the toxic content of fine PM after adding dispersant. A laboratory setup consisted of a vertical tank filled with seawater, 31.5 L airspace for aerosol sampling, and a bubble generating nozzle that aerosolized the oily droplets. Four different cases were studied: no slick, 0....

Highly porous oil sorbent based on hollow fibers as the interceptor for oil on static and running water
Publication date: 15 March 2016 Source:Journal of Hazardous Materials, Volume 305 Author(s): Ting Dong, Shengbin Cao, Guangbiao Xu Highly porous fibrous assembly made by kapok and hollow PET fibers was prepared by the air-laying-bonding method, and used as the interceptor for oils on static and running water. SEM showed that the vast majority of kapok and PET fibers in the assembly was intact and retained their hollow lumens, with the assembly's porosity high to 98.03%. Oil sorption tests exhibited that kapok/PET assembly could absorb 63.00g/g of vegetable oil and 58.50g/g of used motor oil, with high oil retention af...

IJERPH, Vol. 14, Pages 1374: Modeling Skin Injury from Hot Spills on Clothing
g The present work analyzes scald burns from hot beverages, such as coffee and tea, spilled on the lap, i.e., an incident that may occur in daily life. The Pennes bioheat equation is solved numerically for small spills wetting the clothing, i.e., the fabric prevents the spilled liquid from draining away. Temperatures are analyzed in the wetted fabric and the skin layers and the resulting skin injury is calculated based on the basal layer temperature. Parameters influencing burn severity, such as clothing thickness, liquid temperature, removal of fabric and thermal effects of post scald water cooling are analyzed. The f...

Porous amorphous powder form phase-selective organogelator for rapid recovery of leaked aromatics and spilled oils
Publication date: 15 February 2020Source: Journal of Hazardous Materials, Volume 384Author(s): Baohao Zhang, Shipeng Chen, Hao Luo, Bao Zhang, Fumin Wang, Jian SongAbstractPhase-selective organogelators (PSOGs) have drawn wide attention due to their potential applications in recovery of leaked aromatics and spilled oils. However, powder form PSOGs with fast gelling abilities and broad applicabilities are still limited. Herein, we developed three D-gluconic acetal-based gelators with different alkyl chains, all of which show excellent gel properties for hydrocarbon solvents. The spectroscopic and X-ray results revealed that...

Identification of bilge oil with lubricant: Recent oil spill case studies
In this study, bilge oils with different fuel oil/lubricant ratios were prepared and analyzed using a modified version of the CEN/TR methodology (European Committee for Standardization, 2012). As the lubricant content of bilge oil increased, the intensity of the C20-C24 group, which is the commonly-used normalization compound group for fuel oil in the percentage weathering (PW) plot, also changed. Therefore, the mean area of the C15-C18 group, which was affected by the lubricant content, was used instead. Although heavy fuel oil is usually normalized to a hopane, bilge oil with a high lubricant content cannot be analyzed b...

Survival outcomes of rehabilitated riverine turtles following a freshwater diluted bitumen oil spill
Environ Pollut. 2022 Aug 14:119968. doi: 10.1016/j.envpol.2022.119968. Online ahead of print.ABSTRACTRehabilitation is often used to mitigate adverse effects of oil spills on wildlife. With an increase in production of alternatives to conventional crude oil such as diluted bitumen (dilbit), emergency spill responders and wildlife rehabilitators need information regarding the health and survival of free-ranging vertebrates exposed to dilbit under natural conditions. In 2010, one of the largest freshwater oil spills in the United States occurred in the Kalamazoo River in Michigan, when over 3.2 million liters of spilled dilb...

Long-term reproductive impairment in a seabird after the Prestige oil spill.
Abstract Large oil spills are dramatic perturbations on marine ecosystems, and seabirds are one of the worst affected organisms in such events. It has been argued that oil spills may have important long-term consequences on marine organisms, but supporting evidence remains scarce. The European shag (Phalacrocorax aristotelis) was strongly impacted at population level by the Prestige oil spill, the biggest spillage in the eastern North Atlantic. In this paper, we report on the long-term consequences on reproduction of this coastal seabird, using temporal and spatial replicated data (before-after-control-impact desi...
