“…Irwin and colleagues (1997) showed that volatilization in soils accounted for about 20% and 30% of the loss of C 1 -methylnaphthalene and naphthalene, respectively, but for the 12 remaining HMW-PAHs, volatilization was not an important loss mechanism. Given that at low temperature the volatilization of short-chain alkanes is reduced (Yang et al 2009), volatilization of naphthalenes in our microcosms was probably smaller than what was observed in soils, and therefore most losses were likely due to biodegradation.…”

“…Nutrient concentrations should not be a limiting factor if a small amount of contamination occurs during the pre-bloom period, considering that 94% of the initial hydrocarbons were lost within 2 weeks in our oil-treated microcosms. So far, biostimulation (i.e., supply of limiting resources; Brakstad 2008) has been more successful than bioaugmentation in cold environments because the added microorganisms were stressed by the polar conditions and were outcompeted by indigenous species (Yang et al 2009). Biostimulation in winter or early spring, when nutrient concentrations in surface water are elevated, will likely have little effect.…”

Bioremediation of hydrocarbons is a promising mitigation strategy but challenges remain, particularly due to low microbial metabolic rates in cold, ice-covered seas.Hydrocarbon degradation potential of ice-associated microbes collected from the Northwest Passage was investigated. Microcosm incubations were run for 15 days at -1.7°C with and without oil to determine the effects of hydrocarbon exposure on microbial abundance, diversity and activity, and to estimate component-specific hydrocarbon loss. Diversity was assessed with automated ribosomal intergenic spacer analysis and ion torrent 16S rRNA gene sequencing. Bacterial activity was measured by 3 H-leucine uptake rates. After incubation, sub-ice and sea-ice communities degraded 94% and 48% of the initial hydrocarbons, respectively. Hydrocarbon exposure changed the composition of sea-ice and sub-ice communities; in sea-ice microcosms, Bacteroidetes (mainly Polaribacter) dominated whereas in sub-ice microcosms, Epsilonproteobacteria contribution increased, but that of Alphaproteobacteria and Bacteroidetes decreased. Sequencing data revealed a decline in diversity and increases in Colwellia and Moritella in oil-treated microcosms. Low concentration of dissolved organic matter (DOM) in sub-ice seawater may explain higher hydrocarbon degradation when compared to sea ice, where DOM was abundant and composed of labile exopolysaccharides.

“…Even after biostimulation, at least a week is needed for microorganisms to acclimate to the environment and the entire bioremediation process may require months and even years to complete (Atlas, 1995;Zahed et al, 2010). Other environmental factor such as temperature and oxygen are important as temperature affects the viscosity of crude oil and dissolved oxygen affects the metabolic activity of microorganisms (Yang et al, 2009).…”

Problem statement: Anthropogenic activities pollute the oceans with oil through land run off, vessels accidents, periodic tanker discharges and bilge discharges. Oil spills are environmental disasters that impact human, plants and wild life including birds, fish and mammals. Approach: In this study, the International Guidelines for Preventing Oils Spills and Response to Disasters were reviewed and the characteristics of oil spills were discussed. The advantages and disadvantages of various oil spill response methods were evaluated. A comparative analysis were performed on the currently available remediation technologies using 10 evaluation criteria that included cost, efficiency, time, impact on wild life, reliability, level of difficulty, oil recovery, weather, effect on physical/chemical characteristics of oil and the need for further treatment. The advantages and disadvantages of each response method were used to determine the score assigned to that method. Results: There are many government regualtions for individual countries that serve as prevention mesures for oil spills in the offshore environment. They have to do with the design of equipment and machinery used in the offshore environment and performing the necessary safety inspections. The primary objectives of response to oil spill are: to prevent the spill from moving onto shore, reduce the impact on marine life and speed the degradation of any unrecovered oil. There are several physical, chemical, thermal and biological remediation technologies for oil spills including booms, skimmers, sorbents, dispersants, insitu burning and bioremediation. Each technique has its advantages and disadvantages and the choice of a particular technique will depend on: type of oil, physical, biological and economical characteristics of the spill, location, weather and sea conditions, amount spilled and rate of spillage, depth of water column, time of the year and effectiveness of technique. Coclusion: Based on the comparative analysis, oil recovery with mechanical methods and the application of dispersants followed by bioremediation is the most effective response for marine oil spill.

“…A biorremediação é a mais vantajosa dentre estas técnicas testadas, visto que é mais viável economicamente e ainda apresenta menor risco de contaminação secundária (Atlas, 1995, Brito, 2009Juwarkar et al, 2010;Yang et al, 2009).…”

RESUMO -Tivemos como objetivo avaliar a potencialidade da biorremediação em derrames simulados de petróleo com solos da região da Restinga de Jurubatiba. Para isto foram instaladas colunas de experimentação com solo de praia (P1), solo úmido (P2) e um solo seco ao lado do óleoduto OCAB (P3). Foram utilizados Osmocote® (Osm) e NPK, sendo este último aplicado somente ao P3. Alíquotas de solo foram retiradas e realizou-se contagem das unidades formadoras de colônia (UFC). Os resultados mostraram que o crescimento dos microrganismos esteve intimamente ligado à degradação de hidrocarbonetos do petróleo. No P1 o uso de fertilizantes aumentou em 8 vezes a microbiota e levou à uma degradação total dos n-alcanos. No P2, a presença de Osm. aumentou a degradação em 70% comparativamente ao controle, degradando totalmente os n-alcanos. Para o P3 a aplicação do NPK levou a uma presença 2 vezes maior de bactérias comparado à aplicação do Osm. elevando em 48% degradação dos n-alcanos com relação ao controle.(um espaço) INTRODUÇÃOCom a alta demanda da produção e comercialização do petróleo e de seus derivados, os acidentes envolvendo derrames de óleo se tornaram mais frequentes, criando-se com isso uma maior preocupação mundial em relação aos riscos ambientais decorrentes de tais acontecimentos (Ling, 2003). O escoamento de petróleo e derivados entre as fontes de produção, refinarias e centros de consumo são realizados, dentre outras formas, por tubulações subterrâneas. Foram relatados diversos acidentes devido à problemas relacionados a estes dutos pois os mesmos estão sujeitos a erosão, deslizamentos de terra, corrosão, queda de rochas, atos de vandalismo, ação de terceiros, os quais podem ocasionar vazamentos e, em função da alta pressão com que os produtos são bombeados e da periculosidade das substâncias transportadas, os danos ambientais e sócio-econômicos raramente são pequenos (CETESB, 2012
