“…The findings of the current study demonstrated that the LMW PAHs with logK ow values between 3.30 and 4.54 would preferentially partition to the water column rather than associate with sediment particles, which was consistent with the results from previous studies [42,58,59]. Moreover, the application of dispersant could enhance the OSE of HMW PAHs in the sunken oils, especially 4-ring PAHs, which might subsequently cause more severe consequences for marine benthonic organisms [13,18,60]. Therefore, the present study could improve the understanding of the impacts of HFO 380 spillage on aquatic organisms and be complementary to field studies on sunken oils.…”

“…Although the sinking oil has historically accounted for a small percentage of oil spill accidents [10], its environmental impacts on the benthos are of concern [11][12][13][14]. Field and laboratory exposures have demonstrated that the accumulation of sunken oils on the seafloor has far-reaching ecological implications adversely impacting benthic organisms, including corals, fish, and sea urchin [15][16][17][18]. Generally, it has already been considered that the main toxic components of the oil are polycyclic aromatic hydrocarbons (PAHs), a group of ubiquitous persistent organic pollutants, which are composed of two or more fused aromatic rings in linear, angular, or cluster arrangement [19].…”

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 marine benthonic organisms. In the present study, a bench experiment was designed and conducted to investigate the quantitative distribution of polycyclic aromatic hydrocarbons (PAHs) in sunken oils in the presence of chemical dispersant and sediment. The oil sinking efficiency (OSE) of 16 priority total PAHs in the sediment phase was analyzed with different dosages of dispersant. The results showed that the synergistic effect of chemical dispersant and sediment promoted the formation of sunken oils, and the content of PAHs partitioned in the sunken oils increased with the increase of dispersant-to-oil ratios (DORs). Furthermore, with the addition of chemical dispersant, due to the solubility and hydrophobicity of individual PAHs, the high molecular weight (HMW) PAHs with 4–6 rings tended to partition to sediment compared with low molecular weight (LMW) PAHs with 2–3 rings. The synergistic effect of chemical dispersant and sediment could enhance the OSE of HMW PAHs in sunken oils, which might subsequently cause certain risks for marine benthonic organisms.

“…The sensitivity of women and men to PAHs is different. This fact is present in other animal species (Duan, Xiong, Yang, Xiong, & Ding, 2018). The risk of accumulation of PAHs in adipose tissue in women is extremely higher than in men due to their higher body mass (A. J. .…”

Polycyclic aromatic hydrocarbons (PAHs) contain a large group of chemical compounds that have two or more aromatic rings in their structure. These materials are produced from the incomplete burning of organic materials (such as oil, coal, wood, etc.). Natural and human activities have caused these substances to widely enter the human life cycle and affect the body’s health and functioning. After entering the body, these substances accumulate in the lungs, brain, and fat tissue, therefore, due to the high-fat mass in women, this group is more vulnerable to PAH. With the increased concentration of many of these substances in the body, problems such as genetic toxicity, carcinogenesis and mutagenesis occur. In addition to a general look at these damages, specifically how the mutagenesis process and its effects on the body are examined in detail. PAHs can become more active metabolites (BP-7-trans-dihydrodiol, benzo [a] pyrene diol-epoxide) bind to DNA, and cause mutations in DNA strands by producing ROS. PAHs produce harmful metabolites by regulating the activity of xenobiotic pathway enzymes (cytochrome P450, epoxide hydrolase, and peroxidases). For all the above, it is necessary to investigate the mechanism of their effect on the body. Due to the importance of this issue, detailed and comprehensive information is not available in sufficient quantity in this case, thus, in this research, it has been mentioned in detail and at the end of their risk assessment, it has also been examined.

“…Several recent studies have reported that oil-derived PAHs could stimulate reactive oxygen species (ROS) production during their biotransformation, resulting in an elevation of ROS levels in marine organisms [2,29,30]. Overelevation of ROS levels could further induce oxidative damage of the biomacromolecules (including DNA, proteins, and lipids) [31,32], which is known as the primary mechanism involved in cell damage, apoptosis, and tissue injury in marine organisms exposed to oil-derived PAHs [29,[33][34][35][36]. Additionally, numerous studies have documented that elevated temperature could cause physiological (e.g., increased oxygen consumption) and histological (e.g., tissue injury) changes in marine organisms, and it has been suggested that elevated temperature could also disturb the balance between endogenous and exogenous ROS levels and thereby cause an incapacity of the antioxidant defense system [23,[37][38][39][40][41].…”

Currently, global climate change and oil pollution are two main environmental concerns for sea cucumber (Apostichopus japonicus) aquaculture. However, no study has been conducted on the combined effects of elevated temperature and oil pollution on sea cucumber. Therefore, in the present study, we treated sea cucumber with elevated temperature (26 °C) alone, water-accommodated fractions (WAF) of Oman crude oil at an optimal temperature of 16 °C, and Oman crude oil WAF at an elevated temperature of 26 °C for 24 h. Results showed that reactive oxygen species (ROS) level and total antioxidant capacity in WAF at 26 °C treatment were higher than that in WAF at 16 °C treatment, as evidenced by 6.03- and 1.31-fold-higher values, respectively. Oxidative damage assessments manifested that WAF at 26 °C treatment caused much severer oxidative damage of the biomacromolecules (including DNA, proteins, and lipids) than 26 °C or WAF at 16 °C treatments did. Moreover, compared to 26 °C or WAF at 16 °C treatments, WAF at 26 °C treatment induced a significant increase in cellular apoptosis by detecting the caspase-3 activity. Our results revealed that co-exposure to elevated temperature and crude oil could simulate higher ROS levels and subsequently cause much severer oxidative damage and cellular apoptosis than crude oil alone on sea cucumber.
