“…Найбільше накопичення Купруму, Цинку та Плюмбуму відбувається у шкірі, зябрах та печинці, а кадмію та меркурію -у нирках. Накопичення важких металів у організмі коропа звичайного та бичка-кругляка впливає на метаболічні процеси, викликати патологічні зміни у органах та призводити до загибелі риби (Hasan et al, 2023;Olagbemide & Owolabi, 2023;Páez-Osuna et al, 2023).…”

In the Odesa region, heavy metal contamination of fishery water bodies is a pressing problem. The accumulation of heavy metals in fish depends on the physiological and biochemical activity of the organism and the physical and chemical parameters of the water body. Most heavy metals enter the fish's body through the gills, skin, and digestive organs. Copper, zinc, and plumbum accumulate in the skin, gills, and liver, while cadmium and mercury accumulate in the kidneys. The level of heavy metal pollution in the water of the Khadzhibey estuary was measured and determined in 2022–2023. The following methods were used to determine the content of heavy metals in water: atomic emission spectroscopy using an EMAS-200 CCD instrument to determine cadmium, copper, zinc, and plumbum; cold vapor atomic absorption spectroscopy using the “Julia-2M” method to determine the content of mercury. Toxicological studies of water were carried out in the water hygiene and ecology laboratory of the Ukrainian Research Institute of Transport Medicine and at the Department of Veterinary Hygiene, Sanitation, and Expertise of Odesa State Agrarian University. The study found that the content of heavy metals in the water of the Khadzhibey estuary is not constant and fluctuates depending on the season. The maximum levels of heavy metals are observed in summer (plumbum and cadmium) and autumn (zinc, copper and mercury). It was found that cadmium, plumbum, copper, and mercury content does not exceed the maximum permissible levels for marine fisheries. The zinc content in the water of the Khadzhibey estuary exceeds the maximum permitted concentration by 2.65%. The zinc content in the studied water samples is a stress factor affecting the meat quality of common carp (Cyprinus carpio) and round goby (Neogobius melanostomus).

“…Certain fish tissues acquire many heavy metals from both natural and human sources. Different fish species' sections will have different pollutants because of the affinity between heavy metals and different fish tissues (Hasan et al, 2023). Researchers have examined economically important fish species to investigate their heavy metal content and nutritive value.…”

“…The unique structure of the gills allows for easy penetration of ions from water, making them the primary site for the direct absorption of heavy metals from the environment. In addition, heavy metal enrichment in the liver was associated with the induction and bonding of metallothionein, as the liver continuously accumulates, bio-transforms, and detoxifies heavy metals (Ghannam, 2021;Huang et al, 2022;Hasan et al, 2023). Results for fish muscles show that metals are within the allowable limits (FAO/WHO, 2015), while gills and liver are above the limits.…”

“…The human body contains less than 0.01% zinc (Zn) and copper (Cu), and the recommended daily allowance (RDA) is often less than 100 mg/day (Łuczyńska et al, 2022). Excessive (Cu) and (Zn) intake can lead to health complications such as kidney and liver damage (Hasan et al, 2023). On the contrary, nonessential and toxic metals like lead (Pb) and cadmium (Cd) have no biological purpose and can cause cancer.…”

Bardawil Lake is a unique aquatic ecosystem that provides a habitat for various fish and other aquatic organisms. This study aimed to analyze the quality of fish species to make sure this lake, like the rest of the other Egyptian lakes, suffers from the deterioration of fish product quality due to the accumulation of some heavy metals (Cd, Pb, Cu, and Zn) in various tissues from fish species that were caught from this lake. 35 fish samples were caught during spring, 2018; from seven different species: Mugil cephalus, Liza auratus, Sparus aurata, Dicentrarchus labrax, Siganus rivulatus, Anguilla angilla, and Solae Solea. The Association of Official Analytical Chemists methods using a spectrophotometer determined the biochemical composition. In contrast, atomic absorption spectrometry was employed to determine the heavy metals expressed by µg/g wet weight. Results exposed that the accumulation of essential micronutrient (Cu, Zn) content was higher than toxic elements (Cd & Pb) in muscles to Zn > Cu > Pb > Cd. Muscles < gills < liver in all metals except Pb muscles < liver < gills. The metals studied in the muscles were lower than those set by the WHO, and the EU standard. The carcinogenic risk with lower allowable limits of 1x10-6 to 1x10-4 in both normal and high consumption groups; target and total target hazard quotients (THQ & HI) in muscles were <1. The biochemical composition level was highest in the liver, except for protein, which was highest in muscle for all fish species. There is no evidence of harmful contaminants in the muscular tissue of the fish sampled from Bardawil Lake. However, customers should be aware that health concerns may be associated with eating too much fish

“…Many trace elements accumulate in some fish tissues from both natural and human sources. Because of the affinity between trace elements and various fish tissues, different portions of different fish species will contain different contaminants (Hasan et al, 2023). As a result, researchers analyzed economically significant fish species to learn more about trace element content and nutritional value (Huang et al, 2022).…”
