The study examined the presence and health risks of 11 pharmaceutical compounds found in fish and shrimp from the Sea of Marmara, focusing on muscle tissues.
A total of 10 out of the 11 compounds were detected, with ibuprofen being the most prevalent at high concentrations.
The findings suggest that certain compounds, particularly various forms of estrogen, may pose health risks to humans who consume these seafood, highlighting a potential safety concern related to pharmaceutical contamination.

A comparison study analyzed anionic surfactant and phosphate levels in the Turkish Straits System during the fall of 2016 and spring of 2017.
Results showed higher anionic surfactant concentrations at the exit of the system while phosphate levels were lower, with higher phosphate values at the entrance linked to the eutrophic conditions of the Black Sea.
The research is significant for informing the Canal Istanbul Project, as the studied locations are near the proposed construction sites, creating a valuable data foundation.

A one-year study conducted in 2017 monitored the concentrations of alkyl benzene sulphonate (LAS), phosphate, and chlorophyll-a in surface water around the Prince Islands, collecting monthly samples from a single station on each island.
The study found that LAS concentrations ranged from 18.05 to 72.98 μg/L, phosphate from 18.32 to 31.18 mg/L, and chlorophyll-a from 0.31 to 6.35 μg/L throughout the year.
While there were no significant changes in concentrations within the year (p > 0.05), notable differences were found between the different stations (p < 0.05).

Investigations of total petroleum hydrocarbons (TPHs) and polycyclic aromatic hydrocarbons (PAHs) were conducted in the Turkish Straits System during autumn 2016 and spring 2017.
TPH levels ranged from 1.7 to 11.6 μg/l, while PAH concentrations varied from 120 to 2912 ng/g, indicating moderate to high pollution, particularly in areas affected by shipping.
Average petroleum flows were estimated at 1631 tons/year from the Black Sea to the Marmara Sea, and 8484 tons/year from the Marmara Sea to the Aegean Sea, with PAH origins attributed to both pyrolytic and petrogenic sources.

- The study focuses on analyzing polycyclic aromatic hydrocarbons (PAHs) in indigenous mussels (Mytilus galloprovincialis) collected from seven stations in Prince Islands in September 2015.
- Total PAH concentrations in the mussel samples ranged from 664 to 9083 ng/g.
- The PAH origins were identified as pyrolytic on Büyükada and a mix of pyrolytic and petrogenic on other islands based on various chemical ratios.

Researchers analyzed mussels from the Turkish Straits for PAH levels using high performance liquid chromatography (HPLC).
The mussels, chosen for their abundance and role as pollution indicators, revealed total PAH concentrations varying significantly across different locations.
The findings indicated that the Istanbul and Çanakkale Straits are more polluted than the Marmara Sea, with the highest PAH levels found in the Istanbul Strait.
