“…Therefore, the PAHs remediation in the polluted ocean environments has become a critical issue and a global challenge [ 17 ]. Marine oil spills are mainly treated by various combinations of physical methods, chemical methods, and microbial degradation [ 18 , 19 , 20 ], and many new efficient methods have come out in recent years, such as photocatalyst and electro-activated oxidants, etc. [ 21 ].…”

Microbial degradation is a useful tool for inhibiting or preventing polycyclic aromatic hydrocarbons (PAHs) widely distributed in marine environment after oil spill accidents. This study aimed to evaluate the potential and diversity of bacteria Bacillus sp. PAH-2 on Benzo (a) anthracene (BaA), Pyrene (Pyr), and Benzo (a) pyrene (BaP), their composite system, aromatic components system, and crude oil. The seven-day degradation rates against BaA, Pyr, and BaP were 20.6%, 12.83%, and 17.49%, respectively. Further degradation study of aromatic components demonstrated PAH-2 had a high degradation rate of substances with poor stability of molecular structure. In addition, the degradation of PAHs in crude oil suggested PAH-2 not only made good use of PAHs in such a more complex structure of pollutants but the saturated hydrocarbons in the crude oil also showed a good application potential.

“…Regarding the trajectory of the free-rising oil droplet, it is also essentially a reflection of the degree of deformation of the oil droplet [29,43]. While the oil droplet is approximately spherical, the oil droplet basically rises in a straight line, and when the oil droplet is deformed, the trajectory begins to show slight deviations and trajectory oscillations-even a spiral can occur [22,28,29,44]. Further analysis of the oscillation amplitude and oscillation frequency of oil droplets reveals that the equivalent diameter of oil droplets is positively correlated with the amplitude of the motion trajectory as well as the oscillation frequency [29].…”

“…The other portion of the oil will be retained as droplets of varying sizes for a long time in water bodies and form a certain spatial distribution (disregarding the portion that evaporates into the air and enters the sediment) [17][18][19][20][21]. Among these, the surface oil film has been focused on by most researchers due to its practical applicability that can directly show the distance and range of oil spill impacts, while there are relatively few studies on the migration process of oil completely immersed in the water body [22]. Although there are some previous reviews on the basic physical mechanisms of insoluble particles moving in quiescent water, these reviews have mainly focused on deformable fluid particles, i.e., simply considering bubbles and droplets in combination, which has many limitations in practical applications and must be verified in detail on a case-by-case basis before use [23,24].…”

Accidentally spilled oil can cause great harm to the ecological balance of water once it enters the environmental waters. Clarifying its movement behavior and migration law in water has been the focus of environmental hydraulics research. This review starts from the mechanism of the oil spill migration process, and firstly reviews the kinematic characteristics of the smallest moving unit of the oil spill, the individual oil droplet, as well as focusing on several key aspects such as droplet shape, trajectory, terminal velocity and drag coefficient. Subsequently, considering the commonalities and differences between inland riverine and oceanic environments, different aspects of oil droplet collision, coalescence, breakage, particle size distribution, and vertical diffusion are discussed separately. Finally, the current status of research on the migration laws of accidental oil spills in environmental waters is summarized, and feasible future research directions are proposed to address the emerging research problems and research gaps.

“…Only a small portion of the oil rises to the surface to form an oil slick, while most of the oil exists in the water column in the form of oil droplets and mixtures. There is a significant difference between the amount of oil leaving the wellhead and the amount of oil reaching the sea surface, and providing a monitoring feedback mechanism is crucial as a guide for responding to the spill in the short term [5][6][7]. This feedback mechanism can be used to guide subsequent oil spill response work.…”

Acoustic monitoring is an efficient technique for oil spill detection, and the development of acoustic technology is conducive to achieving real-time monitoring of underwater oil spills, providing data references and guidance for emergency response work. Starting from the research background of oil spills, this review summarizes and evaluates the existing research on acoustic technology for monitoring underwater oil spills. Underwater oil spills are more complex than surface oil spills, and further research is needed to investigate the feasibility of acoustic technology in underwater oil spill monitoring, verify the accuracy of monitoring data, and assess its value. In the future, the impact mechanism and dynamic research of acoustic technology in oil spill monitoring should be explored, and the advantages and differences between acoustic technology and other detection techniques should be compared. The significance of auxiliary mechanisms combined with acoustic technology in oil spill monitoring should be studied. Moreover, acoustic research methods and experimental techniques should be enriched and improved to fully tap into the future value of acoustic technology.
