| contents | The seasonal evaluation of heavy metals in sardines from the Mediterranean coast of Damietta, Egypt. Ali, Aisha M Nawareg, Mona M Elgetany, Asmaa H Bahnasawy, Mohamed H Hopcroft, Russell R El-Tohamy, Wael S Metals, Heavy Animals Water Pollutants, Chemical Seasons Environmental Monitoring Egypt Fishes Seafood The accumulation of heavy metals in marine organisms' tissues threatens ecosystems and human populations that depend on seafood as a primary food source. The current study evaluated the impact of four metals-Cd, Cu, and Ni-in four organs (muscles, liver, gills, and gonads) of sardine (Sardinella spp.) collected seasonally from the Damietta coast. We investigated fish metal accumulation (μg/g) and human health risk. The results showed that heavy metal concentrations varied significantly (p < 0.001) by tissue and season. Zn and Cd were higher in the gills, while Cu and Ni were higher in the liver. Most metals were lowest in muscle. Among seasons, Zn was highest in autumn, Cu and Cd were highest in summer, and Ni in spring. The fish tissues were mostly contaminated with Cd and Ni, as indicated by the high pollution index values. The Target Hazard Quotient (THQ) occurred in the order of Cd > Ni > Zn > Cu. Cd may pose a threat through this fish's consumption, as its levels in internal organs exceed the authorities' limits-muscle levels were close to those limits. The estimated daily intake of all metals was below the permissible tolerable daily intake. Under average exposure conditions, the metals target and total hazard quotients yielded safe values |
