Metal Concentrations in Two Bioindicator Fish Species, Merlangius merlangus, Mullus Barbatus, Captured from the West Black Sea Coasts (Bartin) of Turkey

Abstract

The Black Sea is very vulnerable to originating from land based human activities and its health is equally dependent on the coastal and non-coastal states of its basin. Total concentrations of cadmium, copper, zinc, lead, nickel, aluminum, iron, manganese, boron and chromium concentrations were determined in Merlangius merlangus (whiting) and Mullus barbatus found in Amasra in the West Coast of the Black Sea (Turkey). The metal contents that were measured in head and muscle was expressed in μg g(-1) wet weight. On average, while the highest Fe (344.25 μg g(-1)), Mn (10.35 μg g(-1)), Cr (0.96 μg g(-1)) and Al (76.77 μg g(-1)) concentrations were measured in the heads of M. merlangus and the highest Zn (77.99 μg g(-1)), Cu(8.53 μg g(-1)), B (44.83 μg g(-1)), Ni (1.96 μg g(-1)), Cd (0.40 μg g(-1)) and Pb (6.80 μg g(-1)) concentrations were detected in the muscles of M. merlangus. There were significant differences between metal levels of muscles in these two species. In terms of permissible levels reported by WHO FAO and TSE, there is not any risk for human consumption for both M. merlangus and M. barbatus, for Pb.

“…The Ag concentrations found in muscle tissue of Green Tiger Prawn (P. semisulcatus) is lower than the other study done in the Northern East Mediterranean Sea [18] . The Al concentrations found in muscle tissue of Red Mullet (M. barbatus) and Grey Mullet (M. cephalus) are higher than the other study done in the Mediterranean Sea and the Black Sea [15,[18][19][20]25] . The As concentrations found in muscle tissue of Red Mullet (M. barbatus) and Grey Mullet (M. cephalus) are lower than the other study done in the Mediterranean Sea and the others [16,17,23,26] .…”

Níquel en alimentos y factores influyentes en sus niveles, ingesta, biodisponibilidad y toxicidad: una revisión

“…El grado de contaminación por este metal en distintas áreas se puede conocer a través de lo que se conoce como 'bioacumuladores' o 'indicadores biológicos' de contaminación, i.e. ciertos moluscos y crustáceos como el cangrejo rojo, líquenes, hongos y otras plantas que tienen la capacidad de acumularlo en elevadas concentraciones (Fındık & Çiçek, 2011).…”

The factors affecting heavy metal levels in the muscle tissues of whiting (merlangius merlangus) and red mullet (mullus barbatus)

“…Industrial wastes, mining activities and marine sediment geochemical structure are potential sources of heavy metals affecting aquatic ecosystem (Balkıs et al 2007;Alkan et al 2012). Fish, major components of aquatic ecosystems, are protein-rich foodstuffs (Fındık & Çiçek 2011) containing high amounts of unsaturated fatty acids. Moreover, they are very important both economically and ecologically due to their key roles in food webs dynamics.…”
