Potential Usage of Pufferfish Dentin as a Metal Accumulation Indicator
Çiftçi, Nuray | Ayas, Deniz
The pufferfish are non-indigenous species in the Mediterranean Sea that do not have predators in the food chain. Therefore, the determination of heavy metal accumulation in pufferfish species can be considered as natural chelation for the aquatic environment. The present study, the potential usage of dentin tissue as an indicator of heavy metal bioaccumulation was examined in pufferfish species. The accumulation of Co, Cu, Zn, Fe, Mo, Ni, Se, Al, Cd, Pb, As, Cr in dentin, liver, kidney and muscle tissues of four pufferfish species (Lagocephalus sceleratus, Lagocephalus spadiceus, Lagocephalus suezensis, and Torquigener flavimaculosus) were captured in the Göksu River and Yeşjlovacık coasts of Turkey by a commercial trawler. The different bioaccumulation levels were found in each species...
Metal levels of macroalgae from Iskenderun and Mersin Bay Turkey eastern Mediterranean
Çiftçi, Nuray | AYAS, Deniz
This study aimed to determine metals' concentrations (Cr, Se, Fe, Cu, Zn, Cd, V, As, Sr, Pb) in macroalgae species sampled from Iskenderun and Mersin Bay between June-October 2018, and these samples were from the depths of 0 to 2 meters. Inductively coupled plasma mass spectrometer (ICP-MS) technique was used for metal analysis. Differences in the metal levels were analyzed using the ANOVA method. Metal concentrations of samples were found as Fe> Sr> Zn> Cr> Cu> V> Se ≥ As> Pb> Cd and Fe> Sr> Zn> Cr> Pb≥ Cu> V> Se> As> Cd from Iskenderun Bay and Mersin Bay, respectively (p
