Seasonal Variations in the Concentrations of Chemical Elements in the Organs of Selected Marine Fishes from the International Iraqi Waters, NW Arabian Gulf

September 11, 2021 Environment and Earth Science 0

Six different marine fish species: Cynoglossus arel, Carangoides chrysophrys, Euryglossa orientalis, Sardinella longiceps, Siganus canaliculatus, and Parastromateus niger were collected from fishing areas within the international waters of Iraq in the top of the Arabian Gulf located between Kuwait and Saudi Arabia to investigate the accumulation of certain heavy metals (Cd, Cu, Fe, Mn, Ni, Pb, and Zn All of the metals tested were found to accumulate at various amounts in the body. Zn and Fe were found to be the most abundant metals in various organs of the investigated fishes, while Pb was the least abundant. Other metals such as Cd, Cu, Mn, and Ni were alternately used in all organs and throughout the year. Despite having high amounts of Zn and Fe and being unaffected by ambient contaminants, the accumulation of heavy metals in their muscles was relatively modest.
