“…The aliphatic compounds are relatively water soluble (Cohen et al 2001), whereas the higher molecular weight aromatic compounds are not as water soluble and are therefore normally present at very low concentrations in the WAF. The dispersant is hydrocarbon based, which allows for greater concentrations of the crude oil components to enter the water column.…”

The present study aimed to assess the impact of acute exposure to crude oil, dispersed oil, and dispersant alone on the liver of the rabbit fish (Siganus canaliculatus). Histopathological effects in the liver were observed at different time points (3 to 21 days) and different concentrations (3-100% water accommodated fraction [WAF]) to simulate a range of possible oil pollution events. The main alterations observed in this study include lipid accumulation, necrosis, bile stagnation, megalocytosis, cholangitis, and spongiosis hepatis. The liver of fish exposed to WAF, dispersed oil, or dispersant showed significant histopathologic alterations compared with the control fish (Mann-Whitney U test; p < .01). Reaction pattern indices (circulatory, degenerative, proliferative, and inflammatory changes) of treated fish differed significantly from the control groups. There was a significant correlation between exposure time and the occurrence of most lesions (Spearman correlation; p > .05). The present study indicates that oil pollution can cause important alterations to livers of adult rabbit fish and that the dispersed oil is slightly more toxic than crude oil or dispersant.

“…All of these procedures further damage marine ecosystems and, perhaps counterintuitively, increase the amount of time required for ecosystems to recover from the oil spill (Foster et al 1990). The chemical dispersants used to break down oil are toxic (Judson et al 2010, Castranova 2011, Sriram et al 2011, and the combination of oil and dispersant can have stronger negative effects on marine species than the oil alone (George 1961, De Vogelaere and Foster 1994, Cohen et al 2001, Vosyliene et al 2005. Although some algae may possess protective mechanisms against the toxic effects of dispersants (Wolfe et al 1999), protective mechanisms in mammals are as yet poorly understood.…”

ABSTRACT. As oil transportation worldwide continues to increase, many communities are at risk of oil spill disasters and must anticipate and prepare for them. Factors that influence oil spill consequences are myriad and range from the biophysical to the social. We provide a summary literature review and overview framework to help communities systematically consider the factors and linkages that would influence consequences of a potential oil spill. The focus is on spills from oil tanker accidents. Drawing primarily on empirical studies of previous oil spill disasters, we focused on several main domains of interest: the oil spill itself, disaster management, the physical marine environment, marine biology, human health, economy, and policy. Key variables that influence the severity of consequences are identified, and significant interactions between variables are delineated. The framework can be used to clarify the complexity of oil spill impacts, identify lessons that may be transferable from other oil spill disasters, develop scenarios for planning, and inform risk analysis and policy debates in localities that are seeking to understand and reduce their vulnerability to potential spill disasters. As a case study, the framework is used to consider potential oil spills and consequences in Vancouver, Canada. Major increases in oil tanker traffic are anticipated in this region, creating urgent new demands for risk information, disaster management planning, and policy responses. The case study identifies particular conditions that distinguish the Vancouver context from other historic events; in particular, proximity to a densely populated urban area, the type of oil being transported, financial compensation schemes, and local economic structure. Drawing lessons from other oil spill disasters is important but should be undertaken with recognition of these key differences. Some types of impacts that have been relatively inconsequential in previous events may be very significant in a Vancouver case.

“…The use of this indicator makes it possible to assess the quality of the aquatic environment and further predict possible changes in hydrobiocenoses [34,35]. It is known that functional activity of LDG increases with poisoning of hydrobionts with heavy metals, phenols [36][37][38][39], organic pollutants when inhibiting tissue respiration. The growth of LDH activity leads to increased utilization of lactate by various tissues, with the urgent need with tissue damage by toxic, anthropogenic and abiotic factors.…”

Abstract. The article shows the results of studies on the influence of heavy metal ions (manganese, nickel, lead) on the viability and metabolic enzyme activity of marbled crayfish Procambarus virginalis (Lyko, 2017) (Decapoda). Due to the fact that marbled crayfish got into the reservoirs of the Dnipropetrovsk region in 2015, it was necessary to study the possibilities of its adaptation to environmental factors of reservoirs for further prediction of its distribution or even acclimatization under conditions of toxicological contamination of the ponds of the steppe Prydniprovya. In the experiment with marbled crayfish, chronic effects of various concentrations of heavy metal ions on the physiological state and enzyme activity were investigated. The obtained results showed that among the investigated heavy metals nickel ions influenced the weight indexes and mortality of crustaceans the most negatively. According to the results of the research, significant changes were noted in the individual biochemical parameters of marbled crayfish under the influence of manganese, lead and nickel ions. The most significant changes in the activity of lactate dehydrogenase were detected in muscle tissues affected by manganese and nickel ions. A significant decrease in the activity of succinate dehydrogenase in muscle of marbled crayfish was determined after the action of heavy metal ions. Investigation of changes in the activity of alkaline phosphatase under the influence of the ions of manganese, lead and nickel has its own characteristics, which indicates certain violations in the tissues of cell membranes. Changes in the activity of enzymes were also reflected in the overall protein content. In conclusion, changes in these parameters may indicate a rapid biochemical response of crustaceans to the toxic effects of heavy metals.
