Master’s Thesis at the University of Basrah Investigates Parasites as Bioindicators of Heavy Metal Accumulation in Fish
The College of Agriculture at the University of Basrah examined a master’s thesis focusing on the study of parasitic worms as biological indicators for assessing the accumulation of certain heavy metals in the tissues of fish from the Shatt al-Arab River.
The study, presented by master’s student Yasmin Jaafar Razzaq, aimed to estimate the concentrations of elements such as chromium, lead, arsenic, aluminum, and boron, and to compare these levels between fish tissues and the parasites infecting them.
The results indicated that digeneans isolated from Tenualosa ilisha (saboor fish) were effective in reducing the accumulation of chromium and lead, while the acanthocephalan Neoechinorhynchus dimorphospinus demonstrated efficiency in reducing chromium levels in Acanthopagrus latus (green grunt fish).
