Antioxidant Response and Oxidative Stress in the Respiratory Tree of Sea Cucumber (Apostichopus japonicus) Following Exposure to Crude Oil and Chemical Dispersant

Journal of Marine Science and Engineering, 2020
Sea cucumber (Apostichopus japonicus) is mainly cultured in the coastal zone, where it is easily threatened by accidental oil spills. Chemical dispersant is one of the efficient oil spill responses for mitigating the overall environmental damage of oil ...

Distribution of Polycyclic Aromatic Hydrocarbons in Sunken Oils in the Presence of Chemical Dispersant and Sediment

Journal of Marine Science and Engineering, 2019
The formation of sunken oils is mainly dominated by the interaction between spilled oils and sediments. Due to their patchiness and invisibility, cleaning operations become difficult. As a result, sunken oils may cause long-term and significant damage to

Effects of Dispersant on the Petroleum Hydrocarbon Biodegradation and Microbial Communities in Seawater from the Baltic Sea and Norwegian Sea

Microorganisms, 2023
Dispersants have been used in several oil spill accidents, but little information is available on their effectiveness in Baltic Sea conditions with low salinity and cold seawater.

Chemical characterization of oil and water accommodated fraction (WAF) at different temperatures

Results in Engineering, 2022
In this work, the formation and the chemical composition of Water Accommodated Fractions (WAFs) of Intermediate Fuel Oil 180, Naphthenic North Atlantic, and Marine Gas-Oil oils were studied at different temperatures (between 5 and 25 °C) with and without

Lethal and sublethal effects of oil, chemical dispersant, and dispersed oil on the ctenophore Mnemiopsis leidyi

Aquatic Biology, 2015
We established the lethal levels for water-accommodated fractions of Corexit® 9500A chemical dispersant, crude oil (WAF), and dispersed crude oil (CEWAF) for the ctenophore Mnemiopsis leidyi at both 15 and 23°C.

Chemical dispersants and quantification textural fractions by Bouyoucos and pipette methods

Acta Agronómica, 2015
An adequate individualization of particles is required for a correct granulometric analysis in order to quantify the real percent composition of particles in the soil. The aim of this study was to compare the percent of granulometric fractions determined

Remediation of crude oil-contaminated saline water using novel dispersants from fish and lobster wastes

Results in Engineering, 2021
The use of chemical dispersants for oil spill cleanup has been reported to harm marine ecosystem due to their toxic impacts. Finding bio-based alternatives to synthesize crude oil dispersants is essential.

Influence of Pseudomonas aeruginosa Presence in the Biodegradability study of Solvent-based and Water-based Dispersant in Oil Spill Handling

International Journal of Technology, 2014
Oil-Spill Dispersant (OSD) reduces interfacial tensions of oil and water turning oil spill into droplets that makes crude oil easier to be degraded by hydrocarbonoclastic bacteria such as Pseudomonas aeruginosa.
