Metal(loid) accumulation and ecotoxicological assessment in cartilaginous fishes from the Northeastern Mediterranean
Çiftçi, Nuray | AYAS, Deniz
The present study was conducted with the objective of ascertaining the levels of selected metal(loid)s in the muscle, liver, spleen, kidney, stomach, intestinal, and gonad tissues of seven distinct cartilaginous species sampled from Northern Cyprus. This initiative was undertaken to address the dearth of metal bioaccumulation data for cartilaginous species and to elucidate the impact of metal pollution on these species, which are distinguished by their limited reproductive capacity. The samples were obtained from discarded species captured during commercial fishing activities. The metal concentrations in these tissues were subsequently determined using Inductively Coupled Plasma Mass Spectrophotometry (ICP-MS). The results indicated that the kidney tissue of Squalus blainville exhibited th...

Report of Stranding of Striped Dolphin Stenella coeruleoalba (Meyen, 1833) in Mersin Bay (Northeastern Mediterranean Sea, Turkey)
AYAS, Deniz | Çiftçi, Nuray
On 08 April 2019, a mature female striped dolphin Stenella coeruleoalba (Meyen, 1833), 185 cm in length (TL), was found dead across the shores of the Mersin Naval Museum, Mersin on the northeastern Mediterranean coast of Turkey. Striped dolphins may accidentally enter the fishing nets, which may be one of the reasons for their death. Although this species has been classified as Vulnerable in the IUCN list, considering the frequency of deaths among this species, the necessity to develop species conservation strategies for the Mediterranean was once again proven by the death of this individual.
The Comparison of Heavy Metal Level in Surface Water, Sediment and Biota Sampled from the Polluted and Unpolluted Sites in the Northeastern Mediterranean Sea

Sediment samples were analyzed in four different particle sizes which were < 63, 63 ≤ − < 125, 125 ≤ − < 250, 250 ≤ − < 500 μm mesh size. The metal levels in surface water, sediment, and biota samples were analysed with Inductively Coupled Plasma-Mass Spectrometer (ICP-MS). Statistical analysis of the data was...
A Mini-Review on Polycyclic Aromatic Hydrocarbons (PAHs) in Some Smoked Fish
Çiftçi, Nuray | AYAS, Deniz
The effects of sources that cause pollution in the environment in organisms can occur in different ways. The participation of polycyclic aromatic hydrocarbons (PAHs), one of the pollutants caused by organic materials, into aquatic ecosystems by washing from the atmosphere and soil causes accumulation in aquatic ecosystems and is easily transported to the upper trophic zones through the food chain. Consumption of these products with high nutritional value poses a threat to human health. The processing of these products, which are widely consumed as fresh, with different processes is another way to remain under the influence of PAH. As it is known, PAHs are formed as a result of pyrolysis and prosynthesis of organic materials that are not sufficiently burned. In this sense, smoked pr...
POLYCYCLIC AROMATIC HYDROCARBONS IN SEAFOOD FROM THE MEDITERRANEAN SEA.
Çiftçi, Nuray | AYAS, Deniz
Polycyclic aromatic hydrocarbons (PAHs) are organic compounds that are formed as a result of insufficientcombustion of organic compounds and cause pollution in the environment. While its natural resources arevolcanicactivities, forest fires, organic matter decomposition, its anthropogenic resources are fossil fuels andpetroleumderivatives. Aquatic ecosystems constitute the final discharge points of PAHs that mix with the atmosphereandsoil.The transmission of PAHs accumulated in aquatic organisms to the upper trophic zones through the foodchainistransmitted to humans by the consumption of seafood. It is known that there are more than a hundredPAHcompounds in the environment, but 16 of them are considered as priority pollutants due to their carcinogeniceffects.The Mediterranean is highly vul...
