Situación socio económica y ambiental de los productores de Acatzingo Puebla por el derrame de hidrocarburo en suelos agrícolas.
Provedor de dados: 32
Autores: Rivera Pineda, Franklin.
En el presente estudio se aborda el siniestro ocurrido en el municipio de Acatzingo,  Puebla en enero del año 2002. El derrame afectó aproximadamente 50 ha de cultivo, con efectos socioambientales, económicos y de producción en familias campesinas del municipio. Para conocer su impacto ocho años después, se encuestaron 159 productores con características socioeconómicas y productivas similares, 80 con terrenos afectados por el siniestro y 79 no afectados directamente, con el propósito de comparar respuestas en el tiempo. El promedio de hectáreas para cultivo por productor es de 1.7 ha con una media de 0.5 a 0.9 ha que les fueron contaminadas. El estudio mostró que 46.3% de los productores afectados opinó que los suelos aún están contaminados pero un 74% de...

After the Cap: Risk Assessment, Citizen Science and Disaster Recovery
Provedor de dados: 7
Autores: McCormick, Sabrina; George Washington University; sabmc@gwu.edu.
I used the 2010 Deepwater Horizon oil spill to examine how crowdsourcing is used as a new form of citizen science that provides real time assessments of health-related exposures. Assessing risks of an oil spill, or disasters more generally, is a challenge complicated by the situated nature of knowledge-generation that results in differential perceptions and responses. These processes are critical in the case of the British Petroleum spill in the Gulf Coast since the identification of risks promises to have ramifications for multiple social actors, as well as the health status and long-term resilience of communities in the area. Qualitative interviews, ethnographic observations, and video data were collected with local social movement organizations,...

From frequent hurricanes to the Deepwater Horizon oil spill in coastal Louisiana: the impact of regulatory change
Provedor de dados: 7
Autores: Cheong, So-Min; University of Kansas, Department of Geography; somin@ku.edu.
The issue of whether adaptations to past disasters can impede adaptation to new disasters of a different type or intensity will be analyzed by examining the transition from frequent hurricanes to the Deepwater Horizon oil spill in coastal Louisiana. In particular, the effects of changed regulatory structures from the Stafford Act to the Oil Pollution Act of 1990 in response to the Deepwater Horizon oil spill are investigated. The article describes how the federal, state, and local governments adjust. In addition, it illustrates the shifting focus on the environment with the activation of the Oil Pollution Act and the Clean Water Act. It wraps up with a discussion of the uncertainty that is pervasive in the case of the oil spill derived from changed...

Community Adaptation to the Hebei-Spirit Oil Spill
Provedor de dados: 7
Autores: Cheong, So-Min; University of Kansas; somin@ku.edu.
The focus of the research is the significance of dependence for communities to survive and adapt in times of environmental disasters.  It shifts the emphasis on self-reliant communities for survival and examines the types and effects of dependence and external linkages by analyzing the range of community responses that include initial responses, early social impact, compensation, and conflicts after the Hebei-Spirit oil spill in December 2007 in Korea.  The findings reveal that dependence is necessary, and the effects of dependence can be both positive and negative depending on the relations between external entities and affected communities as well as the community capacity to absorb resources and information.

Partially supervised oil-slick detection by SAR imagery using kernel expansion
Provedor de dados: 5
Autores: Mercier, Grégoire; Ardhuin, Fanny.
Spaceborne synthetic aperture radar (SAR) is well adapted to detect ocean pollution independently from daily or weather conditions. In fact, oil slicks have a specific impact on ocean wave spectra. Initial wave spectra may be characterized by three kinds of waves, namely big, medium, and small, which correspond physically to gravity and gravity-capillary waves. The increase of viscosity, due to the presence of oil damps gravity-capillary waves. This induces not only a damping of the backscattering to the sensor but also a damping of the energy of the wave spectra. Thus, local segmentation of wave spectra may be achieved by the segmentation of a multiscale decomposition of the original SAR image. In this paper, a semisupervised oil-slick detection is...

A 3-year survey was made of several biological markers in mussels (Mytilus edulis) exposed in situ to the oil that came ashore after the wreck of the "Erika" tanker on the Brittany (France) coast in December 1999. The mussel response was assessed using a set of 7 biomarkers, most of them related to the metabolism of organic contaminants. After a series of validation tests, data was evaluated for only 5 biomarkers: acety1cholinesterase (AChE), glutathione S-transferase (GST), catalase (CAT), malondialdehyde (MDA) and deoxyribonucleic acid (DNA) adducts. No significant reductions in GST or CAT levels were observed, levels of DNA adducts and MDA were high during the 6 months immediately following the accident and levels of AChE were significantly lower during...

The choice of droplet size probability distribution function for oil spill modeling is not trivial
Provedor de dados: 5
Autores: Faillettaz, Robin; Paris, Claire B.; Vaz, Ana C.; Perlin, Natalie; Aman, Zachary M.; Schlüter, Michael; Murawski, Steven A.
The droplet size distribution (DSD) formed by gas-saturated oil jets is one of the most important characteristics of the flow to understand and model the fate of uncontrolled deep-sea oil spills. The shape of the DSD, generally modeled as a theoretical lognormal, Rosin-Rammler or non-fundamental distribution function, defines the size and the mass volume range of the droplets. Yet, the fundamental DSD shape has received much less attention than the volume median size (d50) and range of the DSD during ten years of research following the Deepwater Horizon (DWH) blowout. To better understand the importance of the distribution function of the droplet size we compare the oil rising time, surface oil mass, and sedimented and beached masses for different DSDs...

Effects of dispersant treated oil upon exploratory behaviour in juvenile European sea bass (Dicentrarchus labrax)
Provedor de dados: 5
Autores: Aimon, Cassandre; Lebigre, Christophe; Le Bayon, Nicolas; Le Floch, Stephane; Claireaux, Guy.
Accidental spills are pervasive pollution in aquatic ecosystems. Resorting to chemical dispersant is one of the most implemented strategies in response to oil spills, but it results in an increase in the bio-availability of oil compounds known to disturb fish neurosensory capacities and hence fish habitat use. While it has become well established that acute oil exposure can cause a range of physiological defects, sub-lethal consequences on animal behaviour have only received recent attention. Here we investigated the effect of an exposure to a 62 h- dispersant treated oil on the exploration tendency (exploratory activity, and avoidance of unfamiliar open areas) of juvenile European sea bass. Three different concentrations of chemically dispersed oil were...

Effect of coastal processes on the distribution and persistence of oil spilled by the Amoco-Cadiz - Preliminary conclusions
Provedor de dados: 5
Autores: D'Ozouville, Laurent; Gundlach, E.r.; Hayes, M.o.
The section of North Brittany contaminated by the "AMOCO-CADIZ" oil spill (17 March 1978) is a low-lying ria coastline dominated by dynamic processes favorable for the rapid dispersion of the oil. Aerial and ground surveys were made of the impacted area on 19 March - 2 April and 20 - 28 April 1978, to detail the distribution and persistence of oil along the shoreline. Oil deposition on the shoreline was primarily controlled by local geomorphology (e.g. rocky headlands, tombolos, crenulate bays, etc..) and wind-driven currents. Our results indicate that approximately 62.000 tons of oil was spread along 123 km of coastline and offshore rocks at the time of our first study. During the second study period, oil was distributed along 375 km of shoreline and...

Etat de la pollution par les hydrocarbures dans l'Aber Benoit
Provedor de dados: 5
Autores: Allen, G.; D'Ozouville, Laurent; L'Yavanc, Jacky.
The Aber Benoît, a small estuary on the North West coast of Brittany was polluted by oil from the Amoco Cadiz oil spill. Preliminary results from water and sediment samples taken in the estuary in May 1978, show that two months after the initial spill, high concentrations of hydrocarbures existed in the water and sediments of the estuary. The Aber Benoît shows a well developed salt wedge and upstream increasing suspended sediment concentrations. Oil was dispersed more or less evenly throughout the water column, in the entire length of the estuary. In the bottom sediments, oil had accumulated to depths of 30 cm. Sand bars appear to induce a trapping of oil in the estuary channel.

Influence of crude oil exposure on cardiac function and thermal tolerance of juvenile rainbow trout and European sea bass
Provedor de dados: 5
Autores: Anttila, Katja; Mauduit, Florian; Le Floch, Stephane; Claireaux, Guy; Nikinmaa, Mikko.
Oil spills pose a threat to aquatic organisms. However, the physiological effects of crude oil on cardiac function and on thermal tolerance of juvenile fish are still poorly understood. Consequently, in this paper, we will present results of two separate experiments where we exposed juvenile rainbow trout and European sea bass to crude oil and made cardiac thermal tolerances and maximum heart rate (fHmax) measurements after 1 week (rainbow trout) and 6-month recovery (sea bass). In both species, the fHmax was lower in crude oil-exposed fish than in the control ones at temperatures below the optimum but this difference disappeared at higher temperatures. More importantly, the oil-exposed fish had significantly higher Arrhenius break point temperature for...

Impacts of oil spills on altimeter waveforms and radar backscatter cross-section
Provedor de dados: 5
Autores: Cheng, Yongcun; Tournadre, Jean; Li, Xiaofeng; Xu, Qing; Chapron, Bertrand.
Ocean surface films can damp short capillary-gravity waves, reduce the surface mean square slope, and induce “sigma0 blooms” in satellite altimeter data. No study has ascertained the effect of such film on altimeter measurements due to lack of film data. The availability of Environmental Response Management Application (ERMA) oil cover, daily oil spill extent and thickness data acquired during the Deepwater Horizon (DWH) oil spill accident provides a unique opportunity to evaluate the impact of surface film on altimeter data. In this study, the Jason-1/2 passes nearest to the DWH platform are analyzed to understand the waveform distortion caused by the spill as well as the variation of σ0 as a function of oil thickness, wind speed and radar band. Jason-1/2...

BP Gulf Science Data Reveals Ineffectual Subsea Dispersant Injection for the Macondo Blowout
Provedor de dados: 5
Autores: Paris, Claire B.; Berenshtein, Igal; Trillo, Marcia L.; Faillettaz, Robin; Olascoaga, Maria J.; Aman, Zachary M.; Schlueter, Micheal; Joye, Samantha B.
After the Deepwater Horizon oil platform explosion, an estimated 172.2 million gallons of gas-saturated oil was discharged uncontrollably into the Gulf of Mexico, causing the largest deep-sea blowout in history. In an attempt to keep the oil submerged, massive quantities of the chemical dispersant Corexit (R) 9500 were deployed 1522 m deep at the gushing riser pipe of the Macondo prospect's wellhead. Understanding the effectiveness of this unprecedented subsea dispersant injection (SSDI) is critical because deepwater drilling is increasing worldwide. Here we use the comprehensive BP Gulf Science Data (GSD) to quantify petroleum dynamics throughout the 87-day long blowout. The spatio-temporal distribution of petroleum hydrocarbons revealed consistent higher...

Deepwater Horizon oil spill impacts on sea turtles could span the Atlantic
Provedor de dados: 5
Autores: Putman, Nathan F.; Abreu-grobois, F. Alberto; Iturbe-darkistade, Inaky; Putman, Emily M.; Richards, Paul M.; Verley, Philippe.
We investigated the extent that the 2010 Deepwater Horizon oil spill potentially affected oceanic-stage sea turtles from populations across the Atlantic. Within an ocean-circulation model, particles were backtracked from the Gulf of Mexico spill site to determine the probability of young turtles arriving in this area from major nesting beaches. The abundance of turtles in the vicinity of the oil spill was derived by forward-tracking particles from focal beaches and integrating population size, oceanic-stage duration and stage-specific survival rates. Simulations indicated that 321 401 (66 199-397 864) green (Chelonia mydas), loggerhead (Caretta caretta) and Kemp's ridley (Lepidochelys kempii) turtles were likely within the spill site. These predictions...

Human alteration of marine ecosystems is substantial and growing. Yet, no adequate methodology exists that provides reliable predictions of how environmental degradation will affect these ecosystems at a relevant level of biological organization. The primary objective of this study was to develop a methodology to evaluate a fish’s capacity to face a well-established environmental challenge, an exposure to chemically dispersed oil, and characterize the long-term consequences. Therefore, we applied high-throughput, non-lethal challenge tests to assess hypoxia tolerance, temperature susceptibility and maximal swimming speed as proxies for a fish’s functional integrity. These whole animal challenge tests were implemented before (1 month) and after (1 month)...

A Coupled Lagrangian-Earth System Model for Predicting Oil Photooxidation
Provedor de dados: 5
Autores: Vaz, Ana C; Faillettaz, Robin; Paris, Claire B.
During the Deepwater Horizon (DWH) blowout, photooxidation of surface oil led to the formation of persistent photooxidized compounds, still found in shoreline sediments a decade later. Studies demonstrated that photooxidation modified both biodegradation rates of the surface oil and the effectiveness of aerial dispersant applications. Despite the significant consequences of this weathering pathway, the lack of measurements prevented photooxidation to be accounted for in the DWH oil budget calculations and in most predictive models. Here we develop a Lagrangian photooxidation module that estimates the dose of solar radiation individual oil droplets receive while moving in the ocean, quantifies the likelihood of photooxidative changes, and continues to track...

Esquisse d'un bilan écologique provisoire de l'impact de la marée noire de l"Amoco-Cadiz" sur le littoral
Provedor de dados: 5
Autores: Chasse, C.
The wreckage of the tanker "AMOCO CADIZ" on the reefs of PORTSALL was the fourth oil spill in ten years on the coast of Brittany : it also is the largest known oil spill in the world. The patches at sea were driven eastward by westerly winds from March 17 to March 23. 140 Km of coast line was polluted. The oil spreaded more slowly towards the north west, south and north west where it spoiled some 375 Km of touristic sea coast and important fishing grounds. The coastline is six kilometers wide ; it includes islands and large reefs. The local tidal currents are very strong and reach more than three knots, during spring tides which may rise up to nine meters in a rough sea conditions. The turbulence of the water soon disper­sed the slicks and mixed the oil...

Autores: Chiffoleau, Jean-francois; Chauvaud, Laurent; Amouroux, David; Barats, Aurélie; Dufour, Aurélie; Pecheyran, Christophe; Roux, Nathalie.
Levels of nickel and vanadium, trace metals found in high concentration in the oil spilled from the "Erika" tanker off Brittany (France) in December 1999 (41 +/- 1 and 87 +/- 3 mg kg(-1) respectively), have been monitored over a one-year period following this accidental event in several benthic invertebrates. Ni and V in mussels (Mytilus edulis) and oysters (Crassostrea gigas) soft tissues were analysed twice a month by graphite furnace atomic absorption spectrometry and a scallop (Pecten maximus) shell daily growth bands were sampled every three bands by laser ablation and analysed by ICP-MS for these two contaminants. Survey data for mollusc tissues were compared with reference data arising from the national monitoring database. Ni concentrations in...

Evaluating the ecological impact of an oil spill is a complex issue requiring coherently articulated examination of the sequence of interactions that link the cell, where contaminants exert their effects, to the ecosystem, where interactions with human activities arise. This sequence of interactions traverses the frontiers between scientific disciplines (chemistry, toxicology, physiology, and fisheries ecology). Using the common sole (Solea solea L.) as a model species for the coastal habitats polluted by the "Erika" oil spill, our research project attempted to define indices of functional integrity that characterised the consequences of fuel exposure at the different biological levels. The coupling of field observations with experimental laboratory work...

Oil spill microcosms experiments were carried out to evaluate the effect of bioemulsificant exopolysaccharide (EPS2003) on quick stimulation of hydrocarbonoclastic bacteria. Early hours of oil spill, were stimulated using an experimental seawater microcosm, supplemented with crude oil and EPS2003 (SW+OIL+EPS2003); this system was monitored for 2 days and compared to control microcosm (only oil-polluted seawater, SW+OIL). Determination of bacterial abundance, heterotrophic cultivable and hydrocarbon-degrading bacteria were carried out. Community composition of marine bacterioplankton was determined by 16S rRNA gene clone libraries. Data obtained indicated that bioemulsificant addition stimulated an increase of total bacterial abundance and, in particular,...
