“…Cadmium is absorbed by fish organisms into the blood, and then taken up from the blood into the tissues. This metal is accumulated in fish tissues, especially in the liver, kidney and spleen, leading to their damage (Jasim 2017;Sun et al, 2019). The kidney is an important organ in the body and the major function of the kidney, in addition to excretory functions, is both to maintain homeostasis and erythropoiesis (Jayakumar et al, 2016;Kaur et al, 2018).…”

The present study was performed to determine the effect of melatonin on cadmium accumulation and haematological parameters changes in females of Prussian carp (Carassius gibelio B.). The fish were exposed to a sublethal concentration of cadmium (0.4 and 4.0 mg/L) without or with melatonin implant (containing 18 mg melatonin hormone) for 1, 4, 7, 10 and 13 weeks. After the 7th week, Cd-exposed fish were divided into two groups. The first group of fish were subjected to depuration in clear water, while the second group remained exposed to the same concentrations of cadmium. After the 10th and 13th weeks of exposure the kidney, spleen, heart and blood were taken in order to determine the cadmium concentration and to analyse haematological parameters. The results of this study showed an increase in the concentration of cadmium in the tissues and blood in fish exposed to the highest dose (4.0 mg/L) of cadmium in water with a dependence on the exposure duration. Additionally, it was shown that melatonin administration reduced the cadmium concentration in the tissues and blood, and melatonin had a protective effect against cadmium accumulation. Moreover, the results showed a significant increase in blood parameters (RBC, Ht and Hb) in fish treated with the highest dose of cadmium. However, implantation of melatonin in cadmium-treated fish resulted in marked improvements in haematological parameters. Thus, melatonin can be a good implementation to alleviate, at least partially, the toxicity of cadmium.

“…Metal concentrations that are too low have unfavorable physiological, histological and morphological impacts (Al-Taee et al, 2020). Contaminant levels in fishes are of special concern because they represented hazards for human and public health (Al-Sarraj, 2013;Jasim, 2017).…”

The Euphrates and Tigris rivers are the main vital water sources in Iraq, and therefore many studies have been conducted on them to find out the reasons for their pollution, and the most important sources of pollution are heavy metals. Heavy metals are usually present in nature. Some of them are necessary for life, but they can become toxic through their accumulation in living organisms, as they cannot be eliminated in ecosystems through natural processes, unlike most organic pollutants, where these elements are one of the dangerous pollutants that enter the freshwater environment and cause an imbalance in the ecological system. This is directly or indirectly reflected on the human beings. These elements enter the plant and animal bodies through the soil, water and air which have been categorized by their ability to bio-accumulate in the tissues of animals and elevate their concentration in the tissue and body fluids. Such bioaccumulation causes toxicity to living organisms and may affect human public health. Fishes are the most susceptible among the aquatic animals to the toxicity of heavy metals. They are a basic food source and animal protein, cheap and economical, with a high nutritional value and the human body needs them on a permanent and continuous basis. Fishes are also commonly used in assessing the health of aquatic organisms. This review is focused on the pathological effects of heavy metals in both fishes and humans.
