This book was released on 2020 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fisheries populations and their ecosystems are negatively impacted by both chronic and acute inputs of pollutants, including oil spills such as the Deepwater Horizon platform blowout in 2010 in the Gulf of Mexico (GoM). After Deepwater Horizon, toxicological studies of demersal fishes of the northern GoM were undertaken to characterize impacts and to establish baseline contaminant levels in the aftermath of the spill. In this study, I quantify polycyclic aromatic hydrocarbon (PAH) concentrations in eight pelagic fish species to demonstrate oil exposure differences between species, region and time. Analysis of biliary PAH metabolite equivalents using high performance liquid chromatography was used to estimate short-term and acute exposure in pelagic fishes (n = 102). Hepatic PAH concentrations of 19 parental PAHs and their alkylated homologs in pelagic liver samples (n = 142) were quantified using QuEChERS extractions and GC/MS/MS to quantify long-term and chronic exposure. The hepatic ∑46PAH (sum of 46 parental and homolog PAH compounds) concentration ranges quantified for all species and regions (21.2 to 468 ng g-1 wet weight) are within the range found previously in the GoM region for demersal and reef fishes. Biliary PAH equivalent ∑3FAC concentrations (fluorescent aromatic compounds of three PAH indicators) ranged from 4,400 to 1,400,000 ng FAC g-1 bile, which were also within the same range as demersal and reef species in this region. However, mean biliary PAH concentrations measured in Yellowfin Tuna (855 μg FAC g-1) from the north central GoM were more than three times higher than Golden Tilefish (263 μg FAC g-1) and 20 times higher than Yellowedge Grouper (Hyporthodus flavolimbatus, 41 μg FAC g-1) collected in the same region. Significant negative relationships between PAH concentrations, biometrics (e.g. fish length), and putative indices of fish health including Fulton’s condition factor and the hepatosomatic index were identified for multiple species. Intraspecies and regional differences were also identified for Greater Amberjack, Seriola dumerili, and Yellowfin Tuna, Thunnus albacares, suggesting variation in PAH sources across region. Produced waters from oil and gas platform discharges among other sources including riverine input, atmospheric deposition, burning of fossil fuels, resuspension of contaminated sediments, and chronically leaking wells are likely contributing to regional differences within species. Furthermore, the high levels of PAH exposure in pelagic species compared to demersal and reef species, indicated by biliary fluorescent aromatic compounds (FACs), warrants further investigation to identify the prominent source of surface water PAHs and the specific physiological species differences that govern the observed high rates of exposure and metabolic clearance for species such as the Yellowfin Tuna.

Download or read book Scenarios and Responses to Future Deep Oil Spills written by Steven A. Murawski and published by Springer. This book was released on 2019-07-04 with total page 542 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has often been said that generals prepare for the next war by re-fighting the last. The Deepwater Horizon (DWH) oil spill was unlike any previous – an underwater well blowout 1,500 meters deep. Much has been learned in the wake of DWH and these lessons should in turn be applied to both similar oil spill scenarios and those arising from “frontier” explorations by the marine oil industry. The next deep oil well blowout may be at 3,000 meters or even deeper. This volume summarizes regional (Gulf of Mexico) and global megatrends in marine oil exploration and production. Research in a number of key areas including the behavior of oil and gas under extreme pressure, impacts on biological resources of the deep sea, and the fate of oil and gas released in spills is synthesized. A number of deep oil spills are simulated with detailed computer models, and the likely effects of the spills and potential mitigation measures used to combat them are compared. Recommended changes in policies governing marine oil exploration and development are proposed, as well as additional research to close critical and emerging knowledge gaps. This volume synthesizes state-of-the-art research in deep oil spill behavior and response. It is thus relevant for government and industry oil spill responders, policy formulators and implementers, and academics and students desiring an in-depth and balanced overview of key issues and uncertainties surrounding the quest for deep oil and potential impacts on the environment.

This book was released on 1989-03-31 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book shows how the biological transport, bioaccumulation, disposition, and toxicity of polycyclic aromatic hydrocarbons (PAH) in the aquatic environment are influenced by the ability or inability of organisms to metabolize these environmental pollutants. Written by leading scientists in the fields of PAH metabolism and toxicity in both aquatic and mammalian systems, this book discusses recent advances in the areas of PAH biogeochemistry and bioaccumulation, microbial degradation, enzymes of activation, and detoxication, metabolism of PAH, and laboratory and field studies on carcinogenic/toxic effects. Additionally, important similarities and differences in metabolism of PAH by aquatic and terrestrial organisms are featured. The discussion of bioavailability, metabolism, and subsequent toxic effects should aid in the assessment of the ecological consequences of PAH in the aquatic environment.

Pampanin and published by Bentham Science Publishers. This book was released on 2017-04-07 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although a lot is known about the influence of Polycyclic Aromatic Hydrocarbons (PAHs) on the marine environment, there are still many unanswered questions. Petrogenic Polycyclic Aromatic Hydrocarbons in the Aquatic Environment is a monograph that sums up basic knowledge about this topic while highlighting current research practices useful in studying the aquatic environment. It starts with an introduction to effect of PAH in the marine environment. It then proceeds to provide information on techniques to monitor PAH levels and investigate the affected environment in order to control the subsequent negative effects. Chapters also detail the carcinogenic and endocrine effects of PAHs on fish as well as the degradation of PAHs by microorganisms. This monograph is a useful reference for environmental science students and professionals learning about the role of PAH in the marine environment.

High concentration of atmospheric PM2.5 in Beijing have been reported since January 2013 and exposure to such high concentrations may cause respiratory, cardiac and lung diseases. Gathering contributions from international experts, this volume provides a valuable reference guide for global researchers and students interested in learning from the East Asian experience.
Download or read book Monitoring Polycyclic Aromatic Hydrocarbon PAH Bioavailability Near Offshore Produced Water Discharges written by TC. Sauer and published by . This book was released on 2000 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Produced water is the largest volume waste associated with production of oil and gas on offshore platforms. Produced water that meets effluent limitations for total oil and grease contains low concentrations of petroleum hydrocarbons, low molecular weight organic acids, and several metals. The U.S. EPA has expressed concern that some of these chemicals could be bioaccumulated to potentially toxic concentrations by marine organisms in the receiving waters of offshore produced water discharges. This paper presents the results of an intensive monitoring study to determine if marine animals bioaccumulate polycyclic aromatic hydrocarbons (PAHs) from produced water discharges to offshore waters of the Gulf of Mexico.

This book was released on 2015-01-03 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: As petroleum exploration expands into, and beyond the waters of the OCS, the potential exists, via accidental spills, to adversely impact pelagic recreational and commercial fisheries. Surface petroleum spills in pelagic waters of the OCS will primarily impact those species of fishes and crustaceans that inhabit the epipelagic zone of the open ocean. Members of this group include several species that command a high monetary and socio-economic value (e.g., tunas, wahoos, and billfishes), as well as ecologically important or indicator species (e.g., flying fishes, ocean sunfishes). Spills in the surface waters are also likely to impact floating Sargassum communities, which contain a diverse and often unique faunal assemblage of fishes and invertebrates and which also serve as important nursery habitats for many fishes belonging to the families Coryphaenidae, Carangidae, Pomacentridae, and Lobotidae.
