The largest issue that humans are currently experiencing in this region is water contamination, which is a very serious matter on many levels. Following its discovery and current global prevalence, oil began to pollute the environment through a variety of industries, including petrochemicals, oil derivatives which are among the most significant pollutants in aquatic environments and marine exploration operations. As a result, an increase in these activities resulted in an abundance of oil pollutants that have a significant impact on the environment, both in terms of quantity and systematic effects under various oil concentrations.
The aquatic system's impact from oil pollution varies as well, depending on the substance's chemical makeup and amount emitted where it accumulates to form a layer that floats on the water's surface. The thin layer of dark sleeping oil’s components, including oxygen, has a negative effect on the process of gaseous exchange. This layer also works to reduce evaporation in the environment, which affects how much rain falls. Additionally, the surface layer of the oil raises the temperature of the water beneath it, which causes a decrease in the amount of dissolved gases as physiological processes increase and the resulting lack of dissolved oxygen to cause the death of some organisms.
There are different types of damage that oil pollution causes to the water environment depending on its chemical composition and quantity. It forms a thin layer that is floating on the water's surface and reduces evaporation in the surrounding area, which negatively affects the process of oxygen exchange. Water lies beneath it, thus when physiological processes increase and dissolved oxygen levels rise, the number of dissolved gases falls and organisms die. Due to their capacity to infiltrate living things and gather within their tissues.
The process known as bioaccumulation occurs when these pollutants enter the bodies of aquatic organisms and are either eliminated from the body or stored in concentrations higher than those found in the surrounding environment. This process is caused by ions adhering to membranes in contact with water and water diffusing through semi-permeable membranes to the body fluid, indicating that the majority of the direct entry of substance chemical coating across the respiratory surface of fish is by diffusion.
The respiratory covering of both young and old fish is a wide and extremely thin barrier between water and blood where hazardous pollutants can enter the fish more quickly and easily through the gills than they can through other routes, such feeding.
As a result, numerous studies have shown how these hydrocarbons and crude oil affect breathing, development, reproduction and other physiological functions. Furthermore, in addition to well-sublethal effects and growth suppression, other studies have mentioned harmful effects on histological alterations. Low population density and behavior of fish, where the current study revealed variations in the degree of bioaccumulation between the various body tissues of the fish, as well as some blood alterations of the common carp fish that encounter these factors in freshwater rivers.
Bioaccumulation
Petroleum hydrocarbon bioaccumulation using fluorescence techniques, this technique can be used to measure the amount of hydrocarbons in fish tissues because fish are thought to be able to accumulate hydrocarbons in their tissues at higher concentrations than in their media. This is especially true in the tissues of their fatty organs, where numerous studies have shown that the majority of pollutants enter through the skin or gills because these organs serve as both entry points for all materials and as sites for the digestion of pollutants.
Pollutant levels within the aquatic system's live organisms rise as a result of this process, surpassing those in the water column.
Oil can cling to fish gills, blocking the interchange of dissolved oxygen with the surrounding water; this can restrict breathing by causing a thick coating of mucus to develop, which is then combined with oil compounds. When fish are exposed to certain low molecular weight petroleum compounds, their quick dissolving in water causes numbness, even at low concentrations because the compounds easily permeate through fatty tissues and cell membranes.
Although there are many different types of environmental pollutants, the most harmful ones are those that are carried by chemicals and have an impact on various environmental components, such as the aquatic system where aquatic life exists.
Even though these organisms are semi-aquatic, they spend their larval stages in the water medium, indicating the vitality of the aquatic environment. For this reason, this study on vital activity was conducted in light of these pollutants and it is evident that heavy metals have an impact on walking, a vital activity that reflects the extent of the toxic effect on aquatic organisms.
Heavy metals affect movement as an indicator of the toxicity of environmental pollution. Additionally, the presence of pollutants in the water environment has detrimental effects and damage to the environment, which in turn reflects on the health of humans and the living organisms that reside in this environment.
