“…The levels of (Cd, Pb, Cu and Zn) in the liver, gills, and muscles of seven species of fish (Mugil cephalus, Liza auratus, Sparus aurata, Dicentrarchus labrax, Siganus rivulatus, Anguilla Angilla, and Solae solea) collected from Bardwil Lake, Egypt presented in for cadmium detoxification, and the liver is the most efficient organ for copper (Garai et al, 2021). The human population is mostly exposed to heavy metals via their consumption of fish and other aquatic animals, where the gills are often believed to be the most vulnerable organ, and muscle is the most widely consumed edible component (Zaghloul et al, 2022). The accumulation of heavy metals in fish tissues varied depending on the size, species, and habitat of the fish, as well as the level of pollution in the water.…”

“…Metals accumulate and are selected in different ways depending on diet and lifestyle. One possible explanation for the higher concentrations of heavy metals in demersal fish is that these fish consume many substrates rich in heavy metals, which promotes heavy metals transfer and accumulation in fish at different trophic levels by the food web (Zaghloul et al, 2022).…”

“…The liver got the highest MPI value among the organs we studied, while the gills and muscles scored the lowest. However, the distribution of metals in fish changes depending on the route of exposure (Zaghloul et al, 2022). Metals may be absorbed by fish either via their diet or by contact with polluted water on their respiratory surfaces.…”

“…Consuming fish muscles from Bardawil Lake has no public health risk, but high-consumption individuals may have adverse consequences from ingesting Cd and Pb found in certain species. Predicting the probable impacts of pollutants on people requires considering the additive effect of contaminants on the population for non-carcinogenic risk (Zaghloul et al, 2022). According to USEPA (2018) recommendations, a THQ value of < 1 indicates no risk to human health or no damaging effects of heavy metals on human health from consuming fish daily.…”

“…Due to the quantity, diversity, and purity of its component amino acids, fish is an excellent protein supply (Barakat et al, 2022). Pollution bio-monitoring uses various fish organs, with the liver being a crucial organ for heavy metal accumulation in fish metabolism (Zaghloul et al, 2022). The muscle is essential to human nutrition and is an excellent instrument for health risk evaluation in heavy metal contamination.…”

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
